riastradh | ld.elf_so(1): Skip the ctype(3) guard pages.
These came in via libc_pic.a. They aren't very useful because
nothing mprotects them in ld.elf_so -- ld.elf_so ignores its own
constructors. We could fill them with gibberish in a feeble attempt
to highlight ctype(3) abuse...or we could just audit ld.elf_so and
save on the memory by.
This uses a .PATH.c reachover for the ctype_.c file rather than
pulling ctype_.pico out of libc_pic.a.
Sampling of space savings:

20-50% reduction in ld.elf_so size isn't too shabby (except this was
all just bloat I had inadvertently caused last month, oops).

Don't need it outside immediate _rtld_donelist_init callers.

rin | Drop -O[01] hacks for vax; no longer necessary for patched GCC 10
PR port-vax/57646: Import major vax toolchain fix by Kalvis Duckmanton
XXXRO: GCC 12 may require hacks for a while, but it turned out that
GCC 12 should be treated differently from older versions; a lot of new
files need -O[01] flags, while some may no longer require it.
I will take a look later.
Note that these hacks are not required if Kalvis's patches for GCC 12
are applied.
Keep doc/HACKS entries for a while (will be sync with update for GCC 12).

joerg | Move compatibility for pre-2.0 ELF binaries into separate file.
Early ELF binaries defined dlopen and friends in crt0.o by
using function pointers in the object handle passed from rtld.
This contract wastes space when many shared objects are allocated
and ties dynamic linker and rest of the system tightly together.
Fake the entry points in a static object and restrict them to the
platforms that had working ELF support at the time. Keep the magic and
version field used by modern crt0.o for all architectures. The checks
will be removed from crt0.o in a follow-up step.

Replace COMBREL with just-in-time check in _rtld_relocate_nonplt_objects.
The COMBREL logic predates thread-safety of the dynamic linker and
breaks the use of shared locks for the common symbol lookup case. It is
unlikely to provide any benefit for lazy binding or PLT lookups, so
provide equivalent functionality in the non-PLT relocation handling loop
by checking if the symbol used by the current relocation is the same as
the one used during the last lookup. No inter-object cachine is done as
it is also unlikely to be benefical.
Testing with Firefox startup on AMD64 shows a small performance gain by
the new method.

joerg | Add TLS support infrastructure. For dynamic binaries, ld.elf_so exports
_rtld_tls_allocate and _rtld_tls_free. libpthread uses this functions to
setup the thread private area of all new threads. ld.elf_so is
responsible for setting up the private area for the initial thread.
Similar functions are called from _libc_init for static binaries, using
dl_iterate_phdr to access the ELF Program Header.
Add test cases to exercise the different TLS storage models. Test cases
are compiled and installed on all platforms, but are skipped on
platforms not marked for TLS support.
This material is based upon work partially supported by
The NetBSD Foundation under a contract with Joerg Sonnenberger.
It is inspired by the TLS support in FreeBSD by Doug Rabson and the
clean ups of the DragonFly port of the original FreeBSD modifications.

mrg | remove almost all the ability to build netbsd with an a.out target.
we're ELF now, and there are many missing checks against OBJECT_FMT.
if we ever consider switching, the we can figure out what new ones
we need but for now it's just clutter.
this doesn't remove any of the support for exec_aout or any actually
required-for-boot a.out support, only the ability to build a netbsd
release in a.out format. ie, most of this code has been dead for
over a decade.
i've tested builds on vax, amd64, i386, mac68k, macppc, sparc, atari,
amiga, shark, cats, dreamcast, landisk, mmeye and x68k. this covers
the 5 MACHINE_ARCH's affected, and all the other arch code touched.
it also includes some actual run-time testing of sparc, i386 and
shark, and i performed binary comparison upon amiga and x68k as well.
some minor details relevant:

thorpej | Only use the MKDYNAMICROOT semantics (i.e. -rpath=/lib,/usr/lib and
-dynamic-linker=/libexec/ld.elf_so) if the BINDIR of the program being
built is /bin or /sbin.
The reason we do this is because now all programs *except* those in
/bin and /sbin (i.e. the "special cases") match the default the compiler
uses, which is what is used for things in e.g. xsrc, pkgsrc, and other
random 3rd party programs.
This is done by decoupling where a shlib is installed from how it
is located. Two new variables, SHLIBINSTALLDIR and SHLINKINSTALLDIR,
contain the former information, and key off MKDYNAMICROOT only. SHLIBDIR
and SHLINKDIR contain the latter, and key off MKDYNAMICROOT and BINDIR.
The SHLIBINSTALLDIR, SHLIBDIR, _LIBSODIR, SHLINKINSTALLDIR, and
SHLINKDIR parameters are moved to a new <bsd.shlib.mk>; see bsd.README
for usage details.

lukem | if SHLINKDIR != /usr/libexec, install compat symlink
|
| 1.41 | 28-Dec-2001 |
lukem | * Add user-controlled mk.conf variables
- SHLIBDIR Location to install shared libraries if ${USE_SHLIBDIR}
is "yes". Defaults to "/usr/lib".
- USE_SHLIBDIR If "yes", install shared libraries in ${SHLIBDIR}
instead of ${LIBDIR}. Defaults to "no".
Sets ${_LIBSODIR} to the appropriate value.
This may be set by individual Makefiles as well.
- SHLINKDIR Location of shared linker. Defaults to "/usr/libexec".
If != "/usr/libexec", change the dynamic-linker
encoded in shared programs
* Set USE_SHLIBDIR for libraries used by /bin and /sbin:
libc libcrypt libcrypto libedit libipsec libkvm libm libmi387
libtermcap libutil libz
* If ${_LIBSODIR} != ${LIBDIR}, add symlinks from ${LIBDIR}/${LIB}.so*
to ${_LIBSODIR}/${LIB}.so* for compatibility.
* Always install /sbin/init statically (for now)
The net effect of these changes depends on how the variables are set:
1.) If nothing is set or changed, there is no change from the
current behaviour:
- Static /bin, /sbin, and bits of /usr/*
- Dynamic rest
- Shared linker is /usr/libexec/ld*so
2.) If the following make variables are set:
LDSTATIC=
SHLINKDIR=/lib
SHLIBDIR=/lib
Then the behaviour becomes:
- Dynamic tools
- .so libraries used by /bin and /sbin are installed to /lib,
with symlinks from /usr/lib/lib*so to -> /lib/lib*so
where appropriate
- Shared linker is /lib/ld*so
3.) As per 2.), but add the following variable:
USE_SHLIBDIR=yes
This forces all .so's to be instaleld in /lib (with compat
symlinks), not just those tagged by their Makefiles to be.
Again, compat symlinks are installed

These updates to the build allow building against include files
and libs in the object tree, if you use a separate object tree,
while maintaining backward compatability with other build methods.
See the notes in src/share/mk/bsd.README for full details. Note
that the `make includes' target now only installs the include files
in the build directory (if you use one--otherwise they go in DESTDIR
just like before); `make install' will install include files in
DESTDIR.

PR/39240: Satoshi Suetake: Don't fail when attempting to resolve weak symbols
when we are doing immediate binding, leave them alone and they will be dealt
with later during lazy binding. From skrll@
Implement negative cache checks for symbol lookups.
Uses the Donelist idea from FreeBSD.
Use alloca(3) instead of local xmalloc for creating our DoneLists.
This allows threaded programs to use us a little better, PR lib/43005.
Implement dl_iterate_phdr.

riz | Apply patch (requested by mrg in ticket #1499):
src/compat version 2. this allows building any number of alternate
library / program target ABIs. rather than duplicating the list of
subdirs and Makefiles to build, it re-traverses the necessary ones.
details:
- add support for MAKEDIRTARGETENV to share/mk
- renames LD32DIR to MLIBDIR
- fixes library builds for some subdirs (more was built than needed)
- fixes /bin & /sbin apps in compat mode
- reduces complexity in src/compat and the rest of the tree
- updates ldd netbsd32 support

The SysV ABI specifies that the symbol hash function should return only 32
bits of hash. Unfortunately due to an implementation bu and the fact that
the return type is unsigned long which is 64 bits in LP64, this can fail
in some cases: "\xff\x0f\x0f\x0f\x0f\x0f\x12". See:

Replace COMBREL with just-in-time check in _rtld_relocate_nonplt_objects.
The COMBREL logic predates thread-safety of the dynamic linker and
breaks the use of shared locks for the common symbol lookup case. It is
unlikely to provide any benefit for lazy binding or PLT lookups, so
provide equivalent functionality in the non-PLT relocation handling loop
by checking if the symbol used by the current relocation is the same as
the one used during the last lookup. No inter-object cachine is done as
it is also unlikely to be benefical.
Testing with Firefox startup on AMD64 shows a small performance gain by
the new method.
Drop symbol number from default branch diagnostic, it isn't set at this
point and most likely not valid either.
Expand symnum, GCC's uninitialized used tracking is too imprecise.
Fix C&P bug. Deal with more MIPS hacks overriding def.
Add last_symnum, move up def and defobj.
Add back symnum, fix debug print.
Replace last use of r_type.
Fix indentation.

Use alignof and not size_t for platforms with non-natural base
alignments.
Mirror the ld.elf_so logic for handling aligning the TLS size.
Most noticable, recompute the start of the TLS area for variant I
relative to the TCB. This makes a difference when the segment size and
base alignment don't agree.
Fix PR/54074 and PR/54093 completely.
More similar to the ld.elf_so logic, it is necessary to align with
p_align first. Also, invert the #ifdef condition for consistency.
Should fix regression for static linking binaries:

Fix interactions of initial-exec TLS model and dlopen
(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.
This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.
(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.
(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.

joerg | Add TLS support infrastructure. For dynamic binaries, ld.elf_so exports
_rtld_tls_allocate and _rtld_tls_free. libpthread uses this functions to
setup the thread private area of all new threads. ld.elf_so is
responsible for setting up the private area for the initial thread.
Similar functions are called from _libc_init for static binaries, using
dl_iterate_phdr to access the ELF Program Header.
Add test cases to exercise the different TLS storage models. Test cases
are compiled and installed on all platforms, but are skipped on
platforms not marked for TLS support.
This material is based upon work partially supported by
The NetBSD Foundation under a contract with Joerg Sonnenberger.
It is inspired by the TLS support in FreeBSD by Doug Rabson and the
clean ups of the DragonFly port of the original FreeBSD modifications.

Add recent ld.elf_so test helpers debug info
ld.elf_so: Add new files to debug/shl.mi.
ld.elf_so: tls_extern dynamic_defabuse_eager must xfail differently.
If a symbol has already been resolved as dynamic TLS, any library
that tries to use it as static TLS cannot be dlopened.
ld.elf_so: Test another edge case of mismatched TLS models.
One library defines a symbol and _doesn't_ use it, so it has no
indication of whether the symbol is for static TLS or dynamic TLS,
and then two other libraries use it in different ways.
ld.elf_so: Test dynamic-then-static abuse via ctor.
ld.elf_so: Fix missing tab in debug/shl.mi in last change.
Fix interactions of initial-exec TLS model and dlopen
(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.
This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.
(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.
(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.
Avoid using uninitialized variable "symnum" when building with DEBUG
enabled by borrowing the rdbg_symname() macro from arch/x86_64.
ld.elf_so: Sprinkle more debug messages on dlopen and error.
PR pkg/57445
Fix MKDEBUGLIB build by adding these installed files to the debug
set list.
XXX
One could argue that these files are not of any use, so why install
them? I don't have a good argument either way, and this is (for
now) a simple work-around for PR bin/57455 Please feel free to
commit a different fix to avoid installing these files at all.
Fix markup of libh_ MKDEBUGLIB=yes only files
TLS variant I archs need to fudge the offset by the size of the TCB.
tests/libexec/ld.elf_so: Fix helper library makefiles.
1. Consolidate logic into a single helper.mk to reduce duplication.
2. Set NO* variables, not MK* variables which are reserved for user.
3. Avoid eager X!= in favour of lazy ${X:sh}.
4. Mark _g.a set list entries obsolete. Never should've been built!

ld.elf_so: New test for extern initial-exec TLS, PR toolchain/50277.
ld.elf_so: Fix extern TLS test to match PR toolchain/50277.
Now it's actually testing the problem.
ld.elf_so: Nix inadvertently committed private test program.
ld.elf_so: Fix set lists for MKDEBUG=yes builds with t_tls_extern.
ld.elf_so: Sprinkle tls debug messages.
ld.elf_so: Make tls alloc debug messages more detailed and greppable.
ld.elf_so: Test variations on PR toolchain/50277.
ld.elf_so: Test extern dynamic TLS too.
ld.elf_so: Factor out logic in TLS tests to make writing more easier.
No functional change intended.
ld.elf_so: Test TLS abuse of static def, dynamic use and vice versa.
ld.elf_so: Shorter test names.
No functional non-cosmetic change intended.
ld.elf_so: Separately test eager and lazy resolution of def tls ptr.
eager: before loading use library
lazy: after loading use library
Add recent ld.elf_so test helpers debug info
ld.elf_so: Add new files to debug/shl.mi.
ld.elf_so: tls_extern dynamic_defabuse_eager must xfail differently.
If a symbol has already been resolved as dynamic TLS, any library
that tries to use it as static TLS cannot be dlopened.
ld.elf_so: Test another edge case of mismatched TLS models.
One library defines a symbol and _doesn't_ use it, so it has no
indication of whether the symbol is for static TLS or dynamic TLS,
and then two other libraries use it in different ways.
ld.elf_so: Test dynamic-then-static abuse via ctor.
ld.elf_so: Fix missing tab in debug/shl.mi in last change.
Fix interactions of initial-exec TLS model and dlopen
(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.
This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.
(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.
(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.
Avoid using uninitialized variable "symnum" when building with DEBUG
enabled by borrowing the rdbg_symname() macro from arch/x86_64.
ld.elf_so: Sprinkle more debug messages on dlopen and error.
PR pkg/57445
Fix MKDEBUGLIB build by adding these installed files to the debug
set list.
One could argue that these files are not of any use, so why install
them? I don't have a good argument either way, and this is (for
now) a simple work-around for PR bin/57455 Please feel free to
commit a different fix to avoid installing these files at all.
Fix markup of libh_ MKDEBUGLIB=yes only files
TLS variant I archs need to fudge the offset by the size of the TCB.
tests/libexec/ld.elf_so: Fix helper library makefiles.
1. Consolidate logic into a single helper.mk to reduce duplication.
2. Set NO* variables, not MK* variables which are reserved for user.
3. Avoid eager X!= in favour of lazy ${X:sh}.
4. Mark _g.a set list entries obsolete. Never should've been built!

joerg | Add TLS support infrastructure. For dynamic binaries, ld.elf_so exports
_rtld_tls_allocate and _rtld_tls_free. libpthread uses this functions to
setup the thread private area of all new threads. ld.elf_so is
responsible for setting up the private area for the initial thread.
Similar functions are called from _libc_init for static binaries, using
dl_iterate_phdr to access the ELF Program Header.
Add test cases to exercise the different TLS storage models. Test cases
are compiled and installed on all platforms, but are skipped on
platforms not marked for TLS support.
This material is based upon work partially supported by
The NetBSD Foundation under a contract with Joerg Sonnenberger.
It is inspired by the TLS support in FreeBSD by Doug Rabson and the
clean ups of the DragonFly port of the original FreeBSD modifications.

Move compatibility for pre-2.0 ELF binaries into separate file.
Early ELF binaries defined dlopen and friends in crt0.o by
using function pointers in the object handle passed from rtld.
This contract wastes space when many shared objects are allocated
and ties dynamic linker and rest of the system tightly together.
Fake the entry points in a static object and restrict them to the
platforms that had working ELF support at the time. Keep the magic and
version field used by modern crt0.o for all architectures. The checks
will be removed from crt0.o in a follow-up step.

The SysV ABI specifies that the symbol hash function should return only 32
bits of hash. Unfortunately due to an implementation bug and the fact that
the return type is unsigned long which is 64 bits in LP64, this can fail
in some cases: "\xff\x0f\x0f\x0f\x0f\x0f\x12". See:

riastradh | ld.elf_so: Implement RELR relocations.
The SHT_RELR-type .relr.dyn section, pointed to by the DT_RELR
dynamic tag, holds compressed R_*_RELATIVE-type relocations,
substantially reducing the disk space occupied by many programs.
This commit adds support in ld.elf_so for relocating dynamically
linked executables with RELR relocations.

riastradh | ld.elf_so: Teach this to handle MIPS PIE rtld debug data.
Adapt t_rtld_r_debug to handle the two MIPS cases too.
XXX t_rtld_r_debug should be tested both as PIE and non-PIE to
exercise both cases.
Context:
The value of a DT_DEBUG .dynamic entry is initialized at load-time,
by ld.elf_so, to a pointer to a data structure set up by ld.elf_so
describing the shared objects loaded by the executable, so debuggers
can find them from, e.g., core dumps. None of this is really
documented anywhere that I can find. Best reference is this post on
the gdb mailing list from a quarter century ago saying there's no
real documentation:
https://web.archive.org/web/20250414021320/https://sourceware.org/pipermail/gdb/2000-April/004509.html
However, on MIPS, the .dynamic section is mapped read-only, so
ld.elf_so can't properly modify it (I imagine technically it could
with some mprotect shenanigans but that's not how it's done on MIPS).
Instead, the linker reserves a location in read/write memory and uses
a DT_MIPS_RLD_MAP entry with a pointer to that location.
However, in position-independent executables, the .dynamic entry
can't have an absolute pointer to that location because it's not
known up front. Instead, the the linker uses a DT_MIPS_RLD_MAP_REL
entry with the relative offset to that location from the Elf_Dyn
entry itself.
I would add a reference for this but it's basically a matter of UTSL
plus some oblique mentions on the web and mailing list discussions:

thorpej | PT_GNU_RELRO segments are arranged such that their vaddr + memsz ends
on a linker common page size boundary. However, if the common page size
used by the linker is less than the VM page size being used by the kernel,
this can end up in the middle of a VM page and when the region is write-
protected, this can cause objects in neighboring .data to get incorrectly
write-protected, resulting in a crash.
Avoid this situation by calculating the end of the RELRO region not by
rounding memsz up to the VM page size, but rather by adding vaddr + memsz
and then truncating to the VM page size.

|
| 1.40 | 09-Mar-2011 |
joerg | Add TLS support infrastructure. For dynamic binaries, ld.elf_so exports
_rtld_tls_allocate and _rtld_tls_free. libpthread uses this functions to
setup the thread private area of all new threads. ld.elf_so is
responsible for setting up the private area for the initial thread.
Similar functions are called from _libc_init for static binaries, using
dl_iterate_phdr to access the ELF Program Header.
Add test cases to exercise the different TLS storage models. Test cases
are compiled and installed on all platforms, but are skipped on
platforms not marked for TLS support.
This material is based upon work partially supported by
The NetBSD Foundation under a contract with Joerg Sonnenberger.
It is inspired by the TLS support in FreeBSD by Doug Rabson and the
clean ups of the DragonFly port of the original FreeBSD modifications.

move the defines for RTLD_ARCH_SUBDIR into a sub-sub-makefile so we can
grab these values via reach-over more easily.
some fixes for PR#40170:
- set NATIVE=yes in the environment for genscripts.sh
- set LIB_PATH to /usr/lib/{sparc,i386} for those scripts
- set use_sysroot to "yes", to enable LIB_PATH to work in genscripts.sh
- get rid of building an a.out-happy ldd (but keep supporting a.out
binaries for the ELF version.)
- convert a.out, elf32 and elf64 support into convience libraries and
link them right ones in. if elf_ldd() fails on 64 bit platforms,
try elf32_ldd() before aout_ldd().
now ldd on 64 bit platforms works for 32 bit binaries, aka PR#40199,
and it seems that all the issues from README are gone too.
add some (uintptr_t) to some casts, so these compile with ELFSIZE=32
*and _LP64. necessary for 32/64 bit combo ldd support.
- rework this a bunch to make it work inside /rescue/ldd.
- fix alpha build.
make sure we set LIBISPRIVATE.

PT_GNU_RELRO segments are arranged such that their vaddr + memsz ends
on a linker common page size boundary. However, if the common page size
used by the linker is less than the VM page size being used by the kernel,
this can end up in the middle of a VM page and when the region is write-
protected, this can cause objects in neighboring .data to get incorrectly
write-protected, resulting in a crash.
Avoid this situation by calculating the end of the RELRO region not by
rounding memsz up to the VM page size, but rather by adding vaddr + memsz
and then truncating to the VM page size.

Changes:
- Add a new field r_ldbase in the r_debug struct.
- Set r_version to 1.
This harmonizes the support with OpenBSD and Linux.
FreeBSD uses version 0 (or no version).
Solaris uses version 2 that is not implemented elsewhere and relies on
SVR4 specific design and interfaces.
Update the code comments as r_debug and link_map is used by other software
than GDB, namely: sanitizers, rump, LLDB.

mycroft | Move the definition of _rtld_list_main so ldd builds again.
|
| 1.20 | 03-Oct-2002 |
mycroft | As seen on tech-userlevel...
There are several optimizations here:
1) Objects on _rtld_list_main do not participate in the DAG structures
at all. This is okay because all symbols must be resolvable at
link/load time, and _rtld_list_main is always searched first, so
any references from those objects must necessarily be resolved to
other objects on _rtld_list_main.
(Making this work completely required setting obj->main a bit
earlier; hence the RTLD_MAIN hack.)
2) Objects on _rtld_list_main are not put on _rtld_list_global,
preventing an extra search.
3) A bit is used to keep track of whether an object is on
_rtld_list_global, so we don't have to do a silly linear search.
4) A small attempt is made to prevent objects being put on the DAG
lists multiple times (using a silly linear search).
The sum of this appears to be a ~10% (.3s) reduction in Mozilla's
startup time on my 800MHz box.
Also, make sure _rtld_objmain->path is always set, just to make the
debug output nicer.
|
| 1.19 | 23-Sep-2002 |
mycroft | Several small changes that shave 7-8% off the simple-exec-loop test:
* Rename _rtld_find_library() to _rtld_load_library(). It now calls
_rtld_load_object() if necessary to actually load the object, rather
than having the caller do it. To do this, it also takes the `mode'
argument that gets passed to _rtld_load_object().
* On a related note, remove _rtld_check_library(), and instead call
_rtld_load_object() to instead try actually loading the object. We
save two extra namei's and a bunch of redundant work (almost
literally the same code) this way.
* In _rtld_map_object(), mmap(2) the first page read-only, rather than
read(2)ing it.
* In _rtld_symlook_obj(), compare the *second* character of the symbol
name before calling strcmp(). (This first character is too
frequently `_', and turns out to not be helpful, in libc.)
* Also in _rtld_symlook_obj(), remove the bogus STT_FUNC special case
-- this also allows removing the `in_plt' argument to
_rtld_symlook_list() and _rtld_symlook_obj().
Also:
* In _rtld_obj_from_addr(), rather than trying to look up `_end' in
the each object, instead use obj->mapsize as the upper bound.

Fix interactions of initial-exec TLS model and dlopen
(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.
This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.
(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.
(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.

thorpej | PT_GNU_RELRO segments are arranged such that their vaddr + memsz ends
on a linker common page size boundary. However, if the common page size
used by the linker is less than the VM page size being used by the kernel,
this can end up in the middle of a VM page and when the region is write-
protected, this can cause objects in neighboring .data to get incorrectly
write-protected, resulting in a crash.
Avoid this situation by calculating the end of the RELRO region not by
rounding memsz up to the VM page size, but rather by adding vaddr + memsz
and then truncating to the VM page size.
Fixes PR toolchain/55043.

Replace COMBREL with just-in-time check in _rtld_relocate_nonplt_objects.
The COMBREL logic predates thread-safety of the dynamic linker and
breaks the use of shared locks for the common symbol lookup case. It is
unlikely to provide any benefit for lazy binding or PLT lookups, so
provide equivalent functionality in the non-PLT relocation handling loop
by checking if the symbol used by the current relocation is the same as
the one used during the last lookup. No inter-object cachine is done as
it is also unlikely to be benefical.
Testing with Firefox startup on AMD64 shows a small performance gain by
the new method.

joerg | Add TLS support infrastructure. For dynamic binaries, ld.elf_so exports
_rtld_tls_allocate and _rtld_tls_free. libpthread uses this functions to
setup the thread private area of all new threads. ld.elf_so is
responsible for setting up the private area for the initial thread.
Similar functions are called from _libc_init for static binaries, using
dl_iterate_phdr to access the ELF Program Header.
Add test cases to exercise the different TLS storage models. Test cases
are compiled and installed on all platforms, but are skipped on
platforms not marked for TLS support.
This material is based upon work partially supported by
The NetBSD Foundation under a contract with Joerg Sonnenberger.
It is inspired by the TLS support in FreeBSD by Doug Rabson and the
clean ups of the DragonFly port of the original FreeBSD modifications.

mycroft | Several small changes that shave 7-8% off the simple-exec-loop test:
* Rename _rtld_find_library() to _rtld_load_library(). It now calls
_rtld_load_object() if necessary to actually load the object, rather
than having the caller do it. To do this, it also takes the `mode'
argument that gets passed to _rtld_load_object().
* On a related note, remove _rtld_check_library(), and instead call
_rtld_load_object() to instead try actually loading the object. We
save two extra namei's and a bunch of redundant work (almost
literally the same code) this way.
* In _rtld_map_object(), mmap(2) the first page read-only, rather than
read(2)ing it.
* In _rtld_symlook_obj(), compare the *second* character of the symbol
name before calling strcmp(). (This first character is too
frequently `_', and turns out to not be helpful, in libc.)
* Also in _rtld_symlook_obj(), remove the bogus STT_FUNC special case
-- this also allows removing the `in_plt' argument to
_rtld_symlook_list() and _rtld_symlook_obj().
Also:
* In _rtld_obj_from_addr(), rather than trying to look up `_end' in
the each object, instead use obj->mapsize as the upper bound.

Return an error when there are too many segments rather than abort()ing.
This way `ldd /usr/libexec/ld.elf_so' doesn't core dump.

switch back to using a file mapping for the initial mapping of a new object.
this allows the kernel to use PMAP_PREFER() to give us better alignment on
platforms that care.

When allocating the entire address space of an object, map an anonymous
region first (using the data/bss protection) covering it, then overlay
the text and data regions at the appropriate offsets within the region,
and then unmap any gap between the text and data.
The previous method of maping the entire address space with the actual
file object itself is incorrect, as it may extend past the end of the
file if the section alignment is large enough.
This bug was the source of the libposix failure on the SPARC and another
similar failure (with libc!) on the Alpha (failure was accompanied by
a "uvn_io: size check fired" message on the console).

in serious need of cleaning and/or a fair bit of reworking. See the README

move the defines for RTLD_ARCH_SUBDIR into a sub-sub-makefile so we can
grab these values via reach-over more easily.
some fixes for PR#40170:
- set NATIVE=yes in the environment for genscripts.sh
- set LIB_PATH to /usr/lib/{sparc,i386} for those scripts
- set use_sysroot to "yes", to enable LIB_PATH to work in genscripts.sh
- get rid of building an a.out-happy ldd (but keep supporting a.out
binaries for the ELF version.)
- convert a.out, elf32 and elf64 support into convience libraries and
link them right ones in. if elf_ldd() fails on 64 bit platforms,
try elf32_ldd() before aout_ldd().
now ldd on 64 bit platforms works for 32 bit binaries, aka PR#40199,
and it seems that all the issues from README are gone too.
add some (uintptr_t) to some casts, so these compile with ELFSIZE=32
*and _LP64. necessary for 32/64 bit combo ldd support.
- rework this a bunch to make it work inside /rescue/ldd.
- fix alpha build.
make sure we set LIBISPRIVATE.
fixes build issues reported by moof.

Replace COMBREL with just-in-time check in _rtld_relocate_nonplt_objects.
The COMBREL logic predates thread-safety of the dynamic linker and
breaks the use of shared locks for the common symbol lookup case. It is
unlikely to provide any benefit for lazy binding or PLT lookups, so
provide equivalent functionality in the non-PLT relocation handling loop
by checking if the symbol used by the current relocation is the same as
the one used during the last lookup. No inter-object cachine is done as
it is also unlikely to be benefical.
Testing with Firefox startup on AMD64 shows a small performance gain by
the new method.
Drop symbol number from default branch diagnostic, it isn't set at this
point and most likely not valid either.
Expand symnum, GCC's uninitialized used tracking is too imprecise.
Fix C&P bug. Deal with more MIPS hacks overriding def.
Add last_symnum, move up def and defobj.
Add back symnum, fix debug print.
Replace last use of r_type.
Fix indentation.
Fix indentation.

ld.elf_so: tls_extern dynamic_defabuse_eager must xfail differently.
If a symbol has already been resolved as dynamic TLS, any library
that tries to use it as static TLS cannot be dlopened.
ld.elf_so: Test another edge case of mismatched TLS models.
One library defines a symbol and _doesn't_ use it, so it has no
indication of whether the symbol is for static TLS or dynamic TLS,
and then two other libraries use it in different ways.
ld.elf_so: Test dynamic-then-static abuse via ctor.
ld.elf_so: Fix missing tab in debug/shl.mi in last change.
Fix interactions of initial-exec TLS model and dlopen
(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.
This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.
(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.
(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.
Avoid using uninitialized variable "symnum" when building with DEBUG
enabled by borrowing the rdbg_symname() macro from arch/x86_64.

PT_GNU_RELRO segments are arranged such that their vaddr + memsz ends
on a linker common page size boundary. However, if the common page size
used by the linker is less than the VM page size being used by the kernel,
this can end up in the middle of a VM page and when the region is write-
protected, this can cause objects in neighboring .data to get incorrectly
write-protected, resulting in a crash.
Avoid this situation by calculating the end of the RELRO region not by
rounding memsz up to the VM page size, but rather by adding vaddr + memsz
and then truncating to the VM page size.
Fixes PR toolchain/55043.

riastradh | ld.elf_so: Implement RELR relocations.
The SHT_RELR-type .relr.dyn section, pointed to by the DT_RELR
dynamic tag, holds compressed R_*_RELATIVE-type relocations,
substantially reducing the disk space occupied by many programs.
This commit adds support in ld.elf_so for relocating dynamically
linked executables with RELR relocations.

riastradh | ld.elf_so(1): Defer RELRO a bit for eagerly-bound (-z now) programs.
GNU binutils links programs a little differently if they're eagerly
bound with -Wl,-z,now. In particular, the part of the .got relocated
for ifuncs is covered by the RELRO region in eagerly-bound programs
(-z now), but not in lazily-bound programs (default).
Presumably this is done under the premise that eagerly-bound programs
will resolve all ifuncs at startup _before_ mprotecting the main
object's RELRO region. But ld.elf_so was mprotecting it first, in
_rtld_do_copy_relocations, and then resolving ifuncs -- at which the
memory locations where it tries to write the resolutions will be
mapped read-only.
(In contrast, for lazily bound programs, ifuncs may also be resolved
lazily, so the locations they relocate are _not_ covered by the RELRO
region and we don't run into any trouble)
To avoid this trouble, for eagerly-bound programs, we defer the RELRO
mprotect of the main object by a little bit -- we move it from
_rtld_do_copy_relocations to just after _rtld_call_init_functions.

joerg | Move compatibility for pre-2.0 ELF binaries into separate file.
Early ELF binaries defined dlopen and friends in crt0.o by
using function pointers in the object handle passed from rtld.
This contract wastes space when many shared objects are allocated
and ties dynamic linker and rest of the system tightly together.
Fake the entry points in a static object and restrict them to the
platforms that had working ELF support at the time. Keep the magic and
version field used by modern crt0.o for all architectures. The checks
will be removed from crt0.o in a follow-up step.

Rework ifunc support to address a number of short comings:
- Move to a shared _rtld_call_ifunc for rel and rela architectures
- Architectures using rel format must patch IRELATIVE non-PLT
relocations like RELATIVE in additition to the later ifunc handling
- Consistently record the delta to the end of the relocation group for
non-PLT IRELATIVE relocations
Hidden ifunc is now supported on all ifunc platforms, even when using
-fno-plt. The combination of -fno-plt and relro is broken due to
incorrect GNU ld output though.

mycroft | Several small changes that shave 7-8% off the simple-exec-loop test:
* Rename _rtld_find_library() to _rtld_load_library(). It now calls
_rtld_load_object() if necessary to actually load the object, rather
than having the caller do it. To do this, it also takes the `mode'
argument that gets passed to _rtld_load_object().
* On a related note, remove _rtld_check_library(), and instead call
_rtld_load_object() to instead try actually loading the object. We
save two extra namei's and a bunch of redundant work (almost
literally the same code) this way.
* In _rtld_map_object(), mmap(2) the first page read-only, rather than
read(2)ing it.
* In _rtld_symlook_obj(), compare the *second* character of the symbol
name before calling strcmp(). (This first character is too
frequently `_', and turns out to not be helpful, in libc.)
* Also in _rtld_symlook_obj(), remove the bogus STT_FUNC special case
-- this also allows removing the `in_plt' argument to
_rtld_symlook_list() and _rtld_symlook_obj().
Also:
* In _rtld_obj_from_addr(), rather than trying to look up `_end' in
the each object, instead use obj->mapsize as the upper bound.

junyoung | Make immediate binding work again by actually implementing
_rtld_relocate_plt_objects(). Note that this is for i386 only;

| 1.65 | 06-Sep-2002 |
mycroft | Pass down an additional flag to _rtld_relocate_nonplt_objects() which
indicates whether we're relocating ld.elf_so itself. Use this in some places
rather than hackish tests on `dodebug'. (The Alpha and HPPA `dodebug' tests
were actually noops, because RTLD_RELOCATE_SELF is not set, and therefore
dodebug is always true.)
|
| 1.64 | 06-Sep-2002 |
mycroft | Introduce a new flag, `isdynamic', which is used to remember whether the
executable was of type ET_DYN. Use this instead of `mainprog' to determine
whether we need to do base-relative fixups of the PLT. (This allows loading
non-relocatable objects, should we desire to do that at some point...)
|
| 1.63 | 06-Sep-2002 |
mycroft | More const poisoning. Now the entire _rtld_bind() path useds a const Obj_Entry.
|
| 1.62 | 06-Sep-2002 |
mycroft | Split _rtld_relocate_plt_object() into two MD functions:
* _rtld_relocate_plt_lazy() fixes up all the relocs pointing to the PLT. (On
most platforms it just does a simple base-relative fixup; on SPARC it does
nothing.)
* _rtld_relocate_plt_object() does immediate binding for a PLT entry.
The basic gist is that this saves a bit of time on SPARC (where the iteration
through the pltrela table was gratuitous), and a little less time on all other
platforms. A whole lot of #ifdef'ed crap is moved out of reloc.c, too.
NOT tested on: hppa sh x86_64
|
| 1.61 | 05-Sep-2002 |
mycroft | A few things:
* Pass a symbol number to _rtld_find_symdef(), not a r_info.
* Don't try to do a symbol lookup when we find an unsupported relocation;
instead get the symbol name from the referencing object's strtab.
* Add preliminary support for `-z combreloc'-style startup optimization on
i386, `#ifdef COMBRELOC'.

riastradh | ld.elf_so(1): Defer RELRO a bit for eagerly-bound (-z now) programs.
GNU binutils links programs a little differently if they're eagerly
bound with -Wl,-z,now. In particular, the part of the .got relocated
for ifuncs is covered by the RELRO region in eagerly-bound programs
(-z now), but not in lazily-bound programs (default).
Presumably this is done under the premise that eagerly-bound programs
will resolve all ifuncs at startup _before_ mprotecting the main
object's RELRO region. But ld.elf_so was mprotecting it first, in
_rtld_do_copy_relocations, and then resolving ifuncs -- at which the
memory locations where it tries to write the resolutions will be
mapped read-only.
(In contrast, for lazily bound programs, ifuncs may also be resolved
lazily, so the locations they relocate are _not_ covered by the RELRO
region and we don't run into any trouble)
To avoid this trouble, for eagerly-bound programs, we defer the RELRO
mprotect of the main object by a little bit -- we move it from
_rtld_do_copy_relocations to just after _rtld_call_init_functions.

ld.elf_so(8): Make fork take a shared, not exclusive, lock.
We only need to ensure that there are no concurrent modifications to
the rtld data structures in flight, since the threads that began
those modifications will not exist in the child and will therefore be
unable to complete them in the child.
A shared lock suffices to ensure there are no such concurrent
modifications in flight; an exclusive lock is not necessary, and can
cause deadlock if fork is executed from a signal handler, which is
explicitly allowed by POSIX (and our own sigaction(2) man page) which
marks fork as async-signal-safe.

riastradh | ld.elf_so(1): Omit needless membar_enter.
The use of membar_enter is to separate atomic r/m/w on a lock from
the body of the critical section so two different critical sections
happen in order:
body of previous critical section;
exit critical section:
membar_exit();
atomic_r/m/w(lock stuff);
enter critical section:
atomic_r/m/w(lock stuff);
membar_enter();
body of next critical section;
_rtld_shared_enter does this, but it _also_ issued an extraneous
membar_enter before the atomic_r/m/w part, which doesn't impose any
semantically important order but may cost some performance.

joerg | Rename __atomic_fork to __locked_fork and give it &errno as argument.
rtld and libc use different storage, so the initial version would

thread-safe errno internally, but that's a more contained internal
issue.

thorpej | PT_GNU_RELRO segments are arranged such that their vaddr + memsz ends
on a linker common page size boundary. However, if the common page size
used by the linker is less than the VM page size being used by the kernel,
this can end up in the middle of a VM page and when the region is write-
protected, this can cause objects in neighboring .data to get incorrectly
write-protected, resulting in a crash.
Avoid this situation by calculating the end of the RELRO region not by
rounding memsz up to the VM page size, but rather by adding vaddr + memsz
and then truncating to the VM page size.

Implement _rtld_gnu_hash() for DT_GNU_HASH.
Adapt existing code to compute all Elf_Hash types, instead of only
the ELF/SYSV one.
Rename _rtld_elf_hash() to _rtld_sysv_hash() to match the GNU toolchain
terminology.
_rtld_gnu_hash() uses Dan Bernstein's string hash function posted eons ago
on comp.lang.c.

joerg | Move compatibility for pre-2.0 ELF binaries into separate file.
Early ELF binaries defined dlopen and friends in crt0.o by
using function pointers in the object handle passed from rtld.
This contract wastes space when many shared objects are allocated
and ties dynamic linker and rest of the system tightly together.
Fake the entry points in a static object and restrict them to the
platforms that had working ELF support at the time. Keep the magic and
version field used by modern crt0.o for all architectures. The checks
will be removed from crt0.o in a follow-up step.

Rework ifunc support to address a number of short comings:
- Move to a shared _rtld_call_ifunc for rel and rela architectures
- Architectures using rel format must patch IRELATIVE non-PLT
relocations like RELATIVE in additition to the later ifunc handling
- Consistently record the delta to the end of the relocation group for
non-PLT IRELATIVE relocations
Hidden ifunc is now supported on all ifunc platforms, even when using
-fno-plt. The combination of -fno-plt and relro is broken due to
incorrect GNU ld output though.

Don't block SIGTRAP so that on architectures where the debugger needs to

_rtld_tls_allocate and _rtld_tls_free. libpthread uses this functions to
setup the thread private area of all new threads. ld.elf_so is
responsible for setting up the private area for the initial thread.
Similar functions are called from _libc_init for static binaries, using
dl_iterate_phdr to access the ELF Program Header.
Add test cases to exercise the different TLS storage models. Test cases
are compiled and installed on all platforms, but are skipped on
platforms not marked for TLS support.
This material is based upon work partially supported by
The NetBSD Foundation under a contract with Joerg Sonnenberger.
It is inspired by the TLS support in FreeBSD by Doug Rabson and the
clean ups of the DragonFly port of the original FreeBSD modifications.

versions in the program's libc. This fix moves the GDB link map
entry for the dynamic linker to the end of the search list, where
its symbols will be found only if they are not found anywhere else."

junyoung | A bit speedup: in _rtld_load_object(), save the number of calls to
strcmp() by performing path name length comparison first. In the test
with Mozilla, the number was reduced to 1068 from 7182 (yes, we saved
6114 strcmp()!).

mycroft | Rearrange _rtld_map_object() a little, so that we don't have to have the first
page of the object double-mapped. Not that it matters much, but someone was
whinging about it.
While I'm at it, nuke obj->phdr and obj->phsize; they're unused.

mycroft | Move the definition of _rtld_list_main so ldd builds again.
|
| 1.84 | 03-Oct-2002 |
mycroft | As seen on tech-userlevel...
There are several optimizations here:
1) Objects on _rtld_list_main do not participate in the DAG structures
at all. This is okay because all symbols must be resolvable at
link/load time, and _rtld_list_main is always searched first, so
any references from those objects must necessarily be resolved to
other objects on _rtld_list_main.
(Making this work completely required setting obj->main a bit
earlier; hence the RTLD_MAIN hack.)
2) Objects on _rtld_list_main are not put on _rtld_list_global,
preventing an extra search.
3) A bit is used to keep track of whether an object is on
_rtld_list_global, so we don't have to do a silly linear search.
4) A small attempt is made to prevent objects being put on the DAG
lists multiple times (using a silly linear search).
The sum of this appears to be a ~10% (.3s) reduction in Mozilla's
startup time on my 800MHz box.
Also, make sure _rtld_objmain->path is always set, just to make the
debug output nicer.
|
| 1.83 | 03-Oct-2002 |
mycroft | Do not put objects on _rtld_list_main on any DAG member list -- any symbol we
will have already been found during the _rtld_list_main walk, so there's no
point in doing it again.

size in our local malloc(). Saves a system call.
Also, since we're now relocated early, we don't need to be careful to avoid
globals, so most of the VARPSZ hacks are eliminated.
|
| 1.68 | 24-Sep-2002 |
mycroft | Um, a little bit of sanity here:
l_addr is always supposed to be obj->relocbase -- or so says the GDB code that
uses it. So, set it to this on all platforms. It already was on VAX
explicitly, and on everything else except MIPS implicitly (because
mapbase==relocbase for all existing shlibs). For some silly/stupid reason, a
new field was created that the MIPS GDB currently uses.
Another MD #ifdef bites it.
|
| 1.67 | 23-Sep-2002 |
mycroft | Several small changes that shave 7-8% off the simple-exec-loop test:
* Rename _rtld_find_library() to _rtld_load_library(). It now calls
_rtld_load_object() if necessary to actually load the object, rather
than having the caller do it. To do this, it also takes the `mode'
argument that gets passed to _rtld_load_object().
* On a related note, remove _rtld_check_library(), and instead call
_rtld_load_object() to instead try actually loading the object. We
save two extra namei's and a bunch of redundant work (almost
literally the same code) this way.
* In _rtld_map_object(), mmap(2) the first page read-only, rather than
read(2)ing it.
* In _rtld_symlook_obj(), compare the *second* character of the symbol
name before calling strcmp(). (This first character is too
frequently `_', and turns out to not be helpful, in libc.)
* Also in _rtld_symlook_obj(), remove the bogus STT_FUNC special case
-- this also allows removing the `in_plt' argument to
_rtld_symlook_list() and _rtld_symlook_obj().
Also:
* In _rtld_obj_from_addr(), rather than trying to look up `_end' in
the each object, instead use obj->mapsize as the upper bound.

rather than hackish tests on `dodebug'. (The Alpha and HPPA `dodebug' tests
were actually noops, because RTLD_RELOCATE_SELF is not set, and therefore
dodebug is always true.)

"Fix a bug that showed up when debugging dynamically linked programs.
References from GDB to "printf" and various other functions would
find the versions in the dynamic linker itself, rather than the
versions in the program's libc. This fix moves the GDB link map
entry for the dynamic linker to the end of the search list, where
its symbols will be found only if they are not found anywhere else."
"printf" isn't true for us, but various libc symbols are, e.g. "malloc".

Implement __cxa_thread_atexit and __cxa_thread_atexit_impl. This
functions are used for destructors of thread_local objects.
If a pending destructor exists, prevent unloading of shared objects.
Introduce __dl_cxa_refcount interface for this purpose. When the last
reference is gone and the object has been dlclose'd before, the
unloading is finalized.
Ideally, __cxa_thread_atexit_impl wouldn't exist, but libstdc++ insists
on providing __cxa_thread_atexit as direct wrapper without further
patching.
Fix filename of new debug file
Add misising DEBUGLIB file
Avoid common declaration.
Drop TLS variant checks, emutls is enough for VAX and Sun2.

PR 57628: at the end of _rtld_init() explicitly initialize the ld.elf_so
local copy of the atomic access support functions for machines that do not
implement all required ops in hardware (like 32bit sparc).
XXX would be better to figure out a way to share this copy with libc
(thereby using half as many RAS sections). But even if we would share it,
we have to init it early enough for ld.elf_so internal uses.

ld.elf_so: tls_extern dynamic_defabuse_eager must xfail differently.
If a symbol has already been resolved as dynamic TLS, any library
that tries to use it as static TLS cannot be dlopened.
ld.elf_so: Test another edge case of mismatched TLS models.
One library defines a symbol and _doesn't_ use it, so it has no
indication of whether the symbol is for static TLS or dynamic TLS,
and then two other libraries use it in different ways.
ld.elf_so: Test dynamic-then-static abuse via ctor.
ld.elf_so: Fix missing tab in debug/shl.mi in last change.
Fix interactions of initial-exec TLS model and dlopen
(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.
This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.
(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.
(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.
Avoid using uninitialized variable "symnum" when building with DEBUG
enabled by borrowing the rdbg_symname() macro from arch/x86_64.
ld.elf_so: Sprinkle more debug messages on dlopen and error.
PR pkg/57445
Fix MKDEBUGLIB build by adding these installed files to the debug
set list.
One could argue that these files are not of any use, so why install
them? I don't have a good argument either way, and this is (for
now) a simple work-around for PR bin/57455 Please feel free to
commit a different fix to avoid installing these files at all.
Fix markup of libh_ MKDEBUGLIB=yes only files
TLS variant I archs need to fudge the offset by the size of the TCB.
tests/libexec/ld.elf_so: Fix helper library makefiles.
1. Consolidate logic into a single helper.mk to reduce duplication.
2. Set NO* variables, not MK* variables which are reserved for user.
3. Avoid eager X!= in favour of lazy ${X:sh}.
4. Mark _g.a set list entries obsolete. Never should've been built!

ld.elf_so(8): Make fork take a shared, not exclusive, lock.
We only need to ensure that there are no concurrent modifications to
the rtld data structures in flight, since the threads that began
those modifications will not exist in the child and will therefore be
unable to complete them in the child.
A shared lock suffices to ensure there are no such concurrent
modifications in flight; an exclusive lock is not necessary, and can
cause deadlock if fork is executed from a signal handler, which is
explicitly allowed by POSIX (and our own sigaction(2) man page) which
marks fork as async-signal-safe.

Introduce intermediate locking for fork, so that the dynamic linker is
in a consistent state. This most importantly avoids races between dlopen
and friends and fork, potentially resulting in dead locks in the child
when it itself tries to acquire locks.
Rename __atomic_fork to __locked_fork and give it &errno as argument.
rtld and libc use different storage, so the initial version would
incorrectly report the failure reason for fork().
There is still a small race condition inside ld.elf_so as it doesn't use
thread-safe errno internally, but that's a more contained internal
issue.

PT_GNU_RELRO segments are arranged such that their vaddr + memsz ends
on a linker common page size boundary. However, if the common page size
used by the linker is less than the VM page size being used by the kernel,
this can end up in the middle of a VM page and when the region is write-
protected, this can cause objects in neighboring .data to get incorrectly
write-protected, resulting in a crash.
Avoid this situation by calculating the end of the RELRO region not by
rounding memsz up to the VM page size, but rather by adding vaddr + memsz
and then truncating to the VM page size.

PR 57628: at the end of _rtld_init() explicitly initialize the ld.elf_so
local copy of the atomic access support functions for machines that do not
implement all required ops in hardware (like 32bit sparc).
XXX would be better to figure out a way to share this copy with libc
(thereby using half as many RAS sections). But even if we would share it,
we have to init it early enough for ld.elf_so internal uses.

The SysV ABI specifies that the symbol hash function should return only 32
bits of hash. Unfortunately due to an implementation bug and the fact that
the return type is unsigned long which is 64 bits in LP64, this can fail
in some cases: "\xff\x0f\x0f\x0f\x0f\x0f\x12". See:

Fix interactions of initial-exec TLS model and dlopen
(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.
This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.
(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.
(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.

bits of hash. Unfortunately due to an implementation bu and the fact that

kamil | Upgrade the SVR4 RTLD r_debug protocol to version 1
Changes:
- Add a new field r_ldbase in the r_debug struct.
- Set r_version to 1.
This harmonizes the support with OpenBSD and Linux.
FreeBSD uses version 0 (or no version).
Solaris uses version 2 that is not implemented elsewhere and relies on
SVR4 specific design and interfaces.
Update the code comments as r_debug and link_map is used by other software
than GDB, namely: sanitizers, rump, LLDB.

joerg | Rename __atomic_fork to __locked_fork and give it &errno as argument.
rtld and libc use different storage, so the initial version would
incorrectly report the failure reason for fork().
There is still a small race condition inside ld.elf_so as it doesn't use
thread-safe errno internally, but that's a more contained internal
issue.
|
| 1.139 | 16-Apr-2020 |
joerg | Introduce intermediate locking for fork, so that the dynamic linker is
in a consistent state. This most importantly avoids races between dlopen

joerg | Move compatibility for pre-2.0 ELF binaries into separate file.
Early ELF binaries defined dlopen and friends in crt0.o by
using function pointers in the object handle passed from rtld.
This contract wastes space when many shared objects are allocated
and ties dynamic linker and rest of the system tightly together.
Fake the entry points in a static object and restrict them to the
platforms that had working ELF support at the time. Keep the magic and
version field used by modern crt0.o for all architectures. The checks
will be removed from crt0.o in a follow-up step.

Rework ifunc support to address a number of short comings:
- Move to a shared _rtld_call_ifunc for rel and rela architectures
- Architectures using rel format must patch IRELATIVE non-PLT
relocations like RELATIVE in additition to the later ifunc handling
- Consistently record the delta to the end of the relocation group for
non-PLT IRELATIVE relocations
Hidden ifunc is now supported on all ifunc platforms, even when using
-fno-plt. The combination of -fno-plt and relro is broken due to
incorrect GNU ld output though.

Introduce __dl_cxa_refcount interface for this purpose. When the last
reference is gone and the object has been dlclose'd before, the
unloading is finalized.
Ideally, __cxa_thread_atexit_impl wouldn't exist, but libstdc++ insists
on providing __cxa_thread_atexit as direct wrapper without further
patching.

| 1.127 | 19-Jun-2017 |
joerg | Replace COMBREL with just-in-time check in _rtld_relocate_nonplt_objects.
The COMBREL logic predates thread-safety of the dynamic linker and
breaks the use of shared locks for the common symbol lookup case. It is
unlikely to provide any benefit for lazy binding or PLT lookups, so
provide equivalent functionality in the non-PLT relocation handling loop
by checking if the symbol used by the current relocation is the same as
the one used during the last lookup. No inter-object cachine is done as
it is also unlikely to be benefical.
Testing with Firefox startup on AMD64 shows a small performance gain by
the new method.

skrll | Resolve dlsym(3) and friends directly so that dlsym(RTLD_NEXT,...) works.
Previously dlsym resolved to the version in crt0.o or libc which would
mean that the caller's shared object couldn't be determined correctly
using __builtin_return_address(0).
Mainly from FreeBSD, but adapted by me. Benefits of this solutions are:
- backward comptibility maintained
- existing broken binaries are fixed with a new ld.elf_so
- __mainprog_obj can be removed from crt0.o
- we do the same thing as FreeBSD
Fixes PR 22067.
OKed by Jason and Christos.

junyoung | A bit speedup: in _rtld_load_object(), save the number of calls to
strcmp() by performing path name length comparison first. In the test
with Mozilla, the number was reduced to 1068 from 7182 (yes, we saved
6114 strcmp()!).

nathanw | Remove "extern const chat *_rtld_error_message;". There is no such

mycroft | Rearrange _rtld_map_object() a little, so that we don't have to have the first
page of the object double-mapped. Not that it matters much, but someone was
whinging about it.
While I'm at it, nuke obj->phdr and obj->phsize; they're unused.

mycroft | As seen on tech-userlevel...
There are several optimizations here:
1) Objects on _rtld_list_main do not participate in the DAG structures
at all. This is okay because all symbols must be resolvable at
link/load time, and _rtld_list_main is always searched first, so
any references from those objects must necessarily be resolved to
other objects on _rtld_list_main.
(Making this work completely required setting obj->main a bit
earlier; hence the RTLD_MAIN hack.)
2) Objects on _rtld_list_main are not put on _rtld_list_global,
preventing an extra search.
3) A bit is used to keep track of whether an object is on
_rtld_list_global, so we don't have to do a silly linear search.
4) A small attempt is made to prevent objects being put on the DAG
lists multiple times (using a silly linear search).
The sum of this appears to be a ~10% (.3s) reduction in Mozilla's
startup time on my 800MHz box.
Also, make sure _rtld_objmain->path is always set, just to make the
debug output nicer.
|
| 1.61 | 03-Oct-2002 |
mycroft | Do not put objects on _rtld_list_main on any DAG member list -- any symbol we
will have already been found during the _rtld_list_main walk, so there's no
point in doing it again.

junyoung | Nuke PAGESIZE.
|
| 1.54 | 24-Sep-2002 |
mycroft | Use/require AT_PAGESZ on all platforms. (The kernel has exported it for ~3
years now.) Use _rtld_pagesz instead of getpagesize() to determine the page
size in our local malloc(). Saves a system call.
Also, since we're now relocated early, we don't need to be careful to avoid
globals, so most of the VARPSZ hacks are eliminated.
|
| 1.53 | 23-Sep-2002 |
mycroft | Several small changes that shave 7-8% off the simple-exec-loop test:
* Rename _rtld_find_library() to _rtld_load_library(). It now calls
_rtld_load_object() if necessary to actually load the object, rather
than having the caller do it. To do this, it also takes the `mode'
argument that gets passed to _rtld_load_object().
* On a related note, remove _rtld_check_library(), and instead call
_rtld_load_object() to instead try actually loading the object. We
save two extra namei's and a bunch of redundant work (almost
literally the same code) this way.
* In _rtld_map_object(), mmap(2) the first page read-only, rather than
read(2)ing it.
* In _rtld_symlook_obj(), compare the *second* character of the symbol
name before calling strcmp(). (This first character is too
frequently `_', and turns out to not be helpful, in libc.)
* Also in _rtld_symlook_obj(), remove the bogus STT_FUNC special case
-- this also allows removing the `in_plt' argument to
_rtld_symlook_list() and _rtld_symlook_obj().
Also:
* In _rtld_obj_from_addr(), rather than trying to look up `_end' in
the each object, instead use obj->mapsize as the upper bound.

any efforts to make it work on other platforms are left to

|
| 1.49 | 13-Sep-2002 |
mycroft | Remove a dumb #ifdef -- if VARPSZ is not defined on sparc, the build will
bomb anyway.
|
| 1.48 | 12-Sep-2002 |
mycroft | Nuke -DRTLD_RELOCATE_SELF and `dodebug' from orbit.
|
| 1.47 | 12-Sep-2002 |
mycroft | Move another declaration that doesn't belong in MI source.
|
| 1.46 | 12-Sep-2002 |
mycroft | _rtld_bind_start() is not used in MI code, so declare it in the MD code.
|
| 1.45 | 06-Sep-2002 |
mycroft | Pass down an additional flag to _rtld_relocate_nonplt_objects() which
indicates whether we're relocating ld.elf_so itself. Use this in some places
rather than hackish tests on `dodebug'. (The Alpha and HPPA `dodebug' tests
were actually noops, because RTLD_RELOCATE_SELF is not set, and therefore
dodebug is always true.)
|
| 1.44 | 06-Sep-2002 |
mycroft | Introduce a new flag, `isdynamic', which is used to remember whether the
executable was of type ET_DYN. Use this instead of `mainprog' to determine
whether we need to do base-relative fixups of the PLT. (This allows loading
non-relocatable objects, should we desire to do that at some point...)
|
| 1.43 | 06-Sep-2002 |
mycroft | More const poisoning. Now the entire _rtld_bind() path useds a const Obj_Entry.
|
| 1.42 | 06-Sep-2002 |
mycroft | Re-poison a lot of consts, now that the mark shite is gone.
|
| 1.41 | 06-Sep-2002 |
mycroft | Split _rtld_relocate_plt_object() into two MD functions:
* _rtld_relocate_plt_lazy() fixes up all the relocs pointing to the PLT. (On
most platforms it just does a simple base-relative fixup; on SPARC it does
nothing.)
* _rtld_relocate_plt_object() does immediate binding for a PLT entry.
The basic gist is that this saves a bit of time on SPARC (where the iteration
through the pltrela table was gratuitous), and a little less time on all other
platforms. A whole lot of #ifdef'ed crap is moved out of reloc.c, too.
NOT tested on: hppa sh x86_64
|
| 1.40 | 05-Sep-2002 |
mycroft | Remove all of the `mark' code. This is responsible for the `undefined PLT
symbol' errors, probably because the increment gets interrupted occasionally by
a signal. In general, _rtld_bind() should not modify ANY internal state.
|
| 1.39 | 05-Sep-2002 |
mycroft | A few things:
* Pass a symbol number to _rtld_find_symdef(), not a r_info.
* Don't try to do a symbol lookup when we find an unsupported relocation;
instead get the symbol name from the referencing object's strtab.
* Add preliminary support for `-z combreloc'-style startup optimization on
i386, `#ifdef COMBRELOC'.
|
| 1.38 | 05-Sep-2002 |
mycroft | Rename _rtld_relocate_nonplt_object() to _rtld_relocate_nonplt_objects(),
and push the outer loop into it. This actually shaves a couple % off startup
time at least on PCs.

PR/39240: Satoshi Suetake: Don't fail when attempting to resolve weak symbols
when we are doing immediate binding, leave them alone and they will be dealt
with later during lazy binding. From skrll@
Implement negative cache checks for symbol lookups.
Uses the Donelist idea from FreeBSD.
Use alloca(3) instead of local xmalloc for creating our DoneLists.
This allows threaded programs to use us a little better, PR lib/43005.
Implement dl_iterate_phdr.
Somewhat taken from FreeBSD. Manual page from OpenBSD.

Implement __cxa_thread_atexit and __cxa_thread_atexit_impl. This
functions are used for destructors of thread_local objects.
If a pending destructor exists, prevent unloading of shared objects.
Introduce __dl_cxa_refcount interface for this purpose. When the last
reference is gone and the object has been dlclose'd before, the
unloading is finalized.
Ideally, __cxa_thread_atexit_impl wouldn't exist, but libstdc++ insists
on providing __cxa_thread_atexit as direct wrapper without further
patching.
Fix filename of new debug file
Add misising DEBUGLIB file
Avoid common declaration.
Drop TLS variant checks, emutls is enough for VAX and Sun2.

Replace COMBREL with just-in-time check in _rtld_relocate_nonplt_objects.
The COMBREL logic predates thread-safety of the dynamic linker and
breaks the use of shared locks for the common symbol lookup case. It is
unlikely to provide any benefit for lazy binding or PLT lookups, so
provide equivalent functionality in the non-PLT relocation handling loop
by checking if the symbol used by the current relocation is the same as
the one used during the last lookup. No inter-object cachine is done as
it is also unlikely to be benefical.
Testing with Firefox startup on AMD64 shows a small performance gain by
the new method.
Drop symbol number from default branch diagnostic, it isn't set at this
point and most likely not valid either.
Expand symnum, GCC's uninitialized used tracking is too imprecise.
Fix C&P bug. Deal with more MIPS hacks overriding def.
Add last_symnum, move up def and defobj.
Add back symnum, fix debug print.
Replace last use of r_type.
Fix indentation.
Fix indentation.

One library defines a symbol and _doesn't_ use it, so it has no
indication of whether the symbol is for static TLS or dynamic TLS,
and then two other libraries use it in different ways.
ld.elf_so: Test dynamic-then-static abuse via ctor.
ld.elf_so: Fix missing tab in debug/shl.mi in last change.
Fix interactions of initial-exec TLS model and dlopen
(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.
This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.
(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.
(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.
Avoid using uninitialized variable "symnum" when building with DEBUG
enabled by borrowing the rdbg_symname() macro from arch/x86_64.
ld.elf_so: Sprinkle more debug messages on dlopen and error.
PR pkg/57445
Fix MKDEBUGLIB build by adding these installed files to the debug
set list.
One could argue that these files are not of any use, so why install
them? I don't have a good argument either way, and this is (for
now) a simple work-around for PR bin/57455 Please feel free to
commit a different fix to avoid installing these files at all.
Fix markup of libh_ MKDEBUGLIB=yes only files
TLS variant I archs need to fudge the offset by the size of the TCB.
tests/libexec/ld.elf_so: Fix helper library makefiles.
1. Consolidate logic into a single helper.mk to reduce duplication.
2. Set NO* variables, not MK* variables which are reserved for user.
3. Avoid eager X!= in favour of lazy ${X:sh}.
4. Mark _g.a set list entries obsolete. Never should've been built!

Introduce intermediate locking for fork, so that the dynamic linker is
in a consistent state. This most importantly avoids races between dlopen
and friends and fork, potentially resulting in dead locks in the child
when it itself tries to acquire locks.
Rename __atomic_fork to __locked_fork and give it &errno as argument.
rtld and libc use different storage, so the initial version would
incorrectly report the failure reason for fork().
There is still a small race condition inside ld.elf_so as it doesn't use
thread-safe errno internally, but that's a more contained internal
issue.

The SysV ABI specifies that the symbol hash function should return only 32

the return type is unsigned long which is 64 bits in LP64, this can fail

Fix interactions of initial-exec TLS model and dlopen
(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.
This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.
(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.
(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.

_rtld_load_object() if necessary to actually load the object, rather
than having the caller do it. To do this, it also takes the `mode'
argument that gets passed to _rtld_load_object().
* On a related note, remove _rtld_check_library(), and instead call
_rtld_load_object() to instead try actually loading the object. We
save two extra namei's and a bunch of redundant work (almost
literally the same code) this way.

joerg | Replace COMBREL with just-in-time check in _rtld_relocate_nonplt_objects.
The COMBREL logic predates thread-safety of the dynamic linker and
breaks the use of shared locks for the common symbol lookup case. It is
unlikely to provide any benefit for lazy binding or PLT lookups, so
provide equivalent functionality in the non-PLT relocation handling loop
by checking if the symbol used by the current relocation is the same as
the one used during the last lookup. No inter-object cachine is done as
it is also unlikely to be benefical.
Testing with Firefox startup on AMD64 shows a small performance gain by
the new method.

- Add __name strong aliases of the dlfcn names in ld.elf_so, so that we have:

mycroft | As seen on tech-userlevel...
There are several optimizations here:
1) Objects on _rtld_list_main do not participate in the DAG structures
at all. This is okay because all symbols must be resolvable at
link/load time, and _rtld_list_main is always searched first, so
any references from those objects must necessarily be resolved to
other objects on _rtld_list_main.
(Making this work completely required setting obj->main a bit
earlier; hence the RTLD_MAIN hack.)
2) Objects on _rtld_list_main are not put on _rtld_list_global,
preventing an extra search.
3) A bit is used to keep track of whether an object is on
_rtld_list_global, so we don't have to do a silly linear search.
4) A small attempt is made to prevent objects being put on the DAG
lists multiple times (using a silly linear search).
The sum of this appears to be a ~10% (.3s) reduction in Mozilla's
startup time on my 800MHz box.
Also, make sure _rtld_objmain->path is always set, just to make the
debug output nicer.

mycroft | Several small changes that shave 7-8% off the simple-exec-loop test:
* Rename _rtld_find_library() to _rtld_load_library(). It now calls
_rtld_load_object() if necessary to actually load the object, rather
than having the caller do it. To do this, it also takes the `mode'
argument that gets passed to _rtld_load_object().
* On a related note, remove _rtld_check_library(), and instead call
_rtld_load_object() to instead try actually loading the object. We
save two extra namei's and a bunch of redundant work (almost
literally the same code) this way.
* In _rtld_map_object(), mmap(2) the first page read-only, rather than
read(2)ing it.
* In _rtld_symlook_obj(), compare the *second* character of the symbol
name before calling strcmp(). (This first character is too
frequently `_', and turns out to not be helpful, in libc.)
* Also in _rtld_symlook_obj(), remove the bogus STT_FUNC special case
-- this also allows removing the `in_plt' argument to
_rtld_symlook_list() and _rtld_symlook_obj().
Also:
* In _rtld_obj_from_addr(), rather than trying to look up `_end' in
the each object, instead use obj->mapsize as the upper bound.

tron | Apply patch (request by skrll in ticket #1702):
Bring "ld.elf_so" (mostly) in sync with NetBSD-current:
- MI and MD (e.g. under NetBSD-alpha) performance improvements
- RTLD_SELF, RTLD_NEXT, RTLD_DEFAULT support
- much better structured code
- closes PR bin/25464

tron | Pull up revision 1.16 via patch (requested by dmcmahill in ticket #1395):
Remove all of the `mark' code. This is responsible for the `undefined
PLT
symbol' errors, probably because the increment gets interrupted
occasionally by
a signal. In general, _rtld_bind() should not modify ANY internal
state.

| 1.35.2.1 | 19-Jul-2004 |
tron | Pull up revision 1.36 (requested by thorpej in ticket #676):
- Change the strong dlfcn names in libc to ___name, and make the __name
versions used by others in libc weak, so that we have:
name: weak
__name: weak
___name: strong
- Add __name strong aliases of the dlfcn names in ld.elf_so, so that
we have:
name: strong
__name: strong
This allows ld.elf_so to self-resolve both the name and __name variants
of the dlfcn functions, the former being required for dlfcn support in
applications, the latter being required for dlfcn support in libc.
Fixes the problem described in:

Replace COMBREL with just-in-time check in _rtld_relocate_nonplt_objects.
The COMBREL logic predates thread-safety of the dynamic linker and
breaks the use of shared locks for the common symbol lookup case. It is
unlikely to provide any benefit for lazy binding or PLT lookups, so
provide equivalent functionality in the non-PLT relocation handling loop
by checking if the symbol used by the current relocation is the same as
the one used during the last lookup. No inter-object cachine is done as
it is also unlikely to be benefical.
Testing with Firefox startup on AMD64 shows a small performance gain by
the new method.
Drop symbol number from default branch diagnostic, it isn't set at this
point and most likely not valid either.
Expand symnum, GCC's uninitialized used tracking is too imprecise.

joerg | Rename __atomic_fork to __locked_fork and give it &errno as argument.
rtld and libc use different storage, so the initial version would
incorrectly report the failure reason for fork().
There is still a small race condition inside ld.elf_so as it doesn't use
thread-safe errno internally, but that's a more contained internal
issue.
|
| 1.3 | 16-Apr-2020 |
joerg | Introduce intermediate locking for fork, so that the dynamic linker is
in a consistent state. This most importantly avoids races between dlopen
and friends and fork, potentially resulting in dead locks in the child
when it itself tries to acquire locks.

Implement __cxa_thread_atexit and __cxa_thread_atexit_impl. This

If a pending destructor exists, prevent unloading of shared objects.
Introduce __dl_cxa_refcount interface for this purpose. When the last
reference is gone and the object has been dlclose'd before, the
unloading is finalized.
Ideally, __cxa_thread_atexit_impl wouldn't exist, but libstdc++ insists
on providing __cxa_thread_atexit as direct wrapper without further
patching.

Implement __cxa_thread_atexit and __cxa_thread_atexit_impl. This
functions are used for destructors of thread_local objects.
If a pending destructor exists, prevent unloading of shared objects.
Introduce __dl_cxa_refcount interface for this purpose. When the last
reference is gone and the object has been dlclose'd before, the
unloading is finalized.
Ideally, __cxa_thread_atexit_impl wouldn't exist, but libstdc++ insists
on providing __cxa_thread_atexit as direct wrapper without further
patching.

Introduce intermediate locking for fork, so that the dynamic linker is
in a consistent state. This most importantly avoids races between dlopen
and friends and fork, potentially resulting in dead locks in the child
when it itself tries to acquire locks.
Rename __atomic_fork to __locked_fork and give it &errno as argument.
rtld and libc use different storage, so the initial version would
incorrectly report the failure reason for fork().
There is still a small race condition inside ld.elf_so as it doesn't use
thread-safe errno internally, but that's a more contained internal
issue.

DTV_MAX_INDEX(dtv) is an _inclusive_ upper bound, i.e., the actual
maximum value of the allowed indices. It is not an exclusive upper
bound -- it is not the number of allowed indices.
This off-by-one doesn't hurt correctness, but it may hurt performance
by using the slow path when the fast path would be safe.

joerg | Fix interactions of initial-exec TLS model and dlopen
(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.
This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.
(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.
(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.

_rtld_tls_allocate and _rtld_tls_free. libpthread uses this functions to
setup the thread private area of all new threads. ld.elf_so is
responsible for setting up the private area for the initial thread.
Similar functions are called from _libc_init for static binaries, using
dl_iterate_phdr to access the ELF Program Header.
Add test cases to exercise the different TLS storage models. Test cases
are compiled and installed on all platforms, but are skipped on
platforms not marked for TLS support.
This material is based upon work partially supported by
The NetBSD Foundation under a contract with Joerg Sonnenberger.
It is inspired by the TLS support in FreeBSD by Doug Rabson and the
clean ups of the DragonFly port of the original FreeBSD modifications.

ld.elf_so: New test for extern initial-exec TLS, PR toolchain/50277.
ld.elf_so: Fix extern TLS test to match PR toolchain/50277.

ld.elf_so: Nix inadvertently committed private test program.
ld.elf_so: Fix set lists for MKDEBUG=yes builds with t_tls_extern.

ld.elf_so: Factor out logic in TLS tests to make writing more easier.
No functional change intended.
ld.elf_so: Test TLS abuse of static def, dynamic use and vice versa.
ld.elf_so: Shorter test names.
No functional non-cosmetic change intended.
ld.elf_so: Separately test eager and lazy resolution of def tls ptr.
eager: before loading use library
lazy: after loading use library
Add recent ld.elf_so test helpers debug info
ld.elf_so: Add new files to debug/shl.mi.
ld.elf_so: tls_extern dynamic_defabuse_eager must xfail differently.
If a symbol has already been resolved as dynamic TLS, any library
that tries to use it as static TLS cannot be dlopened.
ld.elf_so: Test another edge case of mismatched TLS models.
One library defines a symbol and _doesn't_ use it, so it has no
indication of whether the symbol is for static TLS or dynamic TLS,
and then two other libraries use it in different ways.
ld.elf_so: Test dynamic-then-static abuse via ctor.
ld.elf_so: Fix missing tab in debug/shl.mi in last change.
Fix interactions of initial-exec TLS model and dlopen
(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.
This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.
(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.
(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.
Avoid using uninitialized variable "symnum" when building with DEBUG
enabled by borrowing the rdbg_symname() macro from arch/x86_64.
ld.elf_so: Sprinkle more debug messages on dlopen and error.
PR pkg/57445
Fix MKDEBUGLIB build by adding these installed files to the debug
set list.
One could argue that these files are not of any use, so why install
them? I don't have a good argument either way, and this is (for
now) a simple work-around for PR bin/57455 Please feel free to
commit a different fix to avoid installing these files at all.
Fix markup of libh_ MKDEBUGLIB=yes only files
TLS variant I archs need to fudge the offset by the size of the TCB.
tests/libexec/ld.elf_so: Fix helper library makefiles.
1. Consolidate logic into a single helper.mk to reduce duplication.
2. Set NO* variables, not MK* variables which are reserved for user.
3. Avoid eager X!= in favour of lazy ${X:sh}.
4. Mark _g.a set list entries obsolete. Never should've been built!

PR 54093: Align static TLS area to max_align_t.
Use alignof and not size_t for platforms with non-natural base
alignments.
Mirror the ld.elf_so logic for handling aligning the TLS size.
Most noticable, recompute the start of the TLS area for variant I
relative to the TCB. This makes a difference when the segment size and
base alignment don't agree.
Fix PR/54074 and PR/54093 completely.
More similar to the ld.elf_so logic, it is necessary to align with
p_align first. Also, invert the #ifdef condition for consistency.
Should fix regression for static linking binaries:

(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.
(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.
Avoid using uninitialized variable "symnum" when building with DEBUG
enabled by borrowing the rdbg_symname() macro from arch/x86_64.

Fix interactions of initial-exec TLS model and dlopen
(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.
This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.
(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory

The COMBREL logic predates thread-safety of the dynamic linker and

provide equivalent functionality in the non-PLT relocation handling loop
by checking if the symbol used by the current relocation is the same as
the one used during the last lookup. No inter-object cachine is done as
it is also unlikely to be benefical.
Testing with Firefox startup on AMD64 shows a small performance gain by
the new method.

ld.elf_so: Factor out logic in TLS tests to make writing more easier.
No functional change intended.
ld.elf_so: Test TLS abuse of static def, dynamic use and vice versa.
ld.elf_so: Shorter test names.
No functional non-cosmetic change intended.
ld.elf_so: Separately test eager and lazy resolution of def tls ptr.
eager: before loading use library
lazy: after loading use library
Add recent ld.elf_so test helpers debug info
ld.elf_so: Add new files to debug/shl.mi.
ld.elf_so: tls_extern dynamic_defabuse_eager must xfail differently.
If a symbol has already been resolved as dynamic TLS, any library
that tries to use it as static TLS cannot be dlopened.
ld.elf_so: Test another edge case of mismatched TLS models.
One library defines a symbol and _doesn't_ use it, so it has no
indication of whether the symbol is for static TLS or dynamic TLS,
and then two other libraries use it in different ways.
ld.elf_so: Test dynamic-then-static abuse via ctor.
ld.elf_so: Fix missing tab in debug/shl.mi in last change.
Fix interactions of initial-exec TLS model and dlopen
(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.
This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.
(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.
(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.
Avoid using uninitialized variable "symnum" when building with DEBUG
enabled by borrowing the rdbg_symname() macro from arch/x86_64.
ld.elf_so: Sprinkle more debug messages on dlopen and error.
PR pkg/57445
Fix MKDEBUGLIB build by adding these installed files to the debug
set list.
One could argue that these files are not of any use, so why install
them? I don't have a good argument either way, and this is (for
now) a simple work-around for PR bin/57455 Please feel free to
commit a different fix to avoid installing these files at all.
Fix markup of libh_ MKDEBUGLIB=yes only files
TLS variant I archs need to fudge the offset by the size of the TCB.
tests/libexec/ld.elf_so: Fix helper library makefiles.
1. Consolidate logic into a single helper.mk to reduce duplication.
2. Set NO* variables, not MK* variables which are reserved for user.
3. Avoid eager X!= in favour of lazy ${X:sh}.
4. Mark _g.a set list entries obsolete. Never should've been built!

First cut at an ELF shared loader. Originally from John Polstra's FreeBSD elf
kit, then hacked on by Matt Thomas <matt@3am-software.com>, then by me (to

Fix interactions of initial-exec TLS model and dlopen
(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.
This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.
(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.
(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.

joerg | Replace COMBREL with just-in-time check in _rtld_relocate_nonplt_objects.
The COMBREL logic predates thread-safety of the dynamic linker and
breaks the use of shared locks for the common symbol lookup case. It is
unlikely to provide any benefit for lazy binding or PLT lookups, so
provide equivalent functionality in the non-PLT relocation handling loop
by checking if the symbol used by the current relocation is the same as
the one used during the last lookup. No inter-object cachine is done as
it is also unlikely to be benefical.
Testing with Firefox startup on AMD64 shows a small performance gain by
the new method.

Add basic support for indirect functions. It allows providing a public
function symbol with an implementation choosen at run time.
Refactor calls to functions by address in ld.elf_so to create temporary
function descriptors on the stack, if the address is not leaked outside.
Limitations:
- no support for initialising static storage with function pointers
- no support for unnamed resolver functions

uint64_t on alpha.
Alpha no longer uses non-standard definitions of Elf64_Sword and
Elf64_Word. Remove the ability to override these types.

thorpej | Fix a serious performance problem for large programs on the Alpha.
Large programs need multiple GOTs. The lazy binding stub in the PLT
can be reached from any of these GOTs, but the dynamic linker only
has enough information to fix up the first GOT entry. Thus, calls
through the other GOTs went through the time-consuming lazy binding
process on every call.
This fix rewrites the PLT entries themselves to bypass the lazy binding
for those GOT entries that the dynamic linker can't fixup.
Fix from FreeBSD.
Note that now that we patch up the PLT, we need to put back the "imb"
that was removed from the binder exit path.
|
| 1.13 | 06-Sep-2002 |
mycroft | Pass down an additional flag to _rtld_relocate_nonplt_objects() which
indicates whether we're relocating ld.elf_so itself. Use this in some places
rather than hackish tests on `dodebug'. (The Alpha and HPPA `dodebug' tests
were actually noops, because RTLD_RELOCATE_SELF is not set, and therefore
dodebug is always true.)
|
| 1.12 | 06-Sep-2002 |
mycroft | Introduce a new flag, `isdynamic', which is used to remember whether the
executable was of type ET_DYN. Use this instead of `mainprog' to determine
whether we need to do base-relative fixups of the PLT. (This allows loading
non-relocatable objects, should we desire to do that at some point...)

mycroft | Re-poison a lot of consts, now that the mark shite is gone.
|
| 1.10 | 06-Sep-2002 |
mycroft | Split _rtld_relocate_plt_object() into two MD functions:
* _rtld_relocate_plt_lazy() fixes up all the relocs pointing to the PLT. (On
most platforms it just does a simple base-relative fixup; on SPARC it does
nothing.)
* _rtld_relocate_plt_object() does immediate binding for a PLT entry.
The basic gist is that this saves a bit of time on SPARC (where the iteration
through the pltrela table was gratuitous), and a little less time on all other
platforms. A whole lot of #ifdef'ed crap is moved out of reloc.c, too.
NOT tested on: hppa sh x86_64

* Pass a symbol number to _rtld_find_symdef(), not a r_info.
* Don't try to do a symbol lookup when we find an unsupported relocation;
instead get the symbol name from the referencing object's strtab.
* Add preliminary support for `-z combreloc'-style startup optimization on
i386, `#ifdef COMBRELOC'.

One library defines a symbol and _doesn't_ use it, so it has no

and then two other libraries use it in different ways.
ld.elf_so: Test dynamic-then-static abuse via ctor.
ld.elf_so: Fix missing tab in debug/shl.mi in last change.
Fix interactions of initial-exec TLS model and dlopen
(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.
This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.
(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.
(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.
Avoid using uninitialized variable "symnum" when building with DEBUG
enabled by borrowing the rdbg_symname() macro from arch/x86_64.

thorpej | Fix a serious performance problem for large programs on the Alpha.
Large programs need multiple GOTs. The lazy binding stub in the PLT
can be reached from any of these GOTs, but the dynamic linker only
has enough information to fix up the first GOT entry. Thus, calls
through the other GOTs went through the time-consuming lazy binding
process on every call.
This fix rewrites the PLT entries themselves to bypass the lazy binding
for those GOT entries that the dynamic linker can't fixup.
Fix from FreeBSD.
Note that now that we patch up the PLT, we need to put back the "imb"
that was removed from the binder exit path.

Fix interactions of initial-exec TLS model and dlopen
(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.
This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.
(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.
(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.

joerg | Replace COMBREL with just-in-time check in _rtld_relocate_nonplt_objects.
The COMBREL logic predates thread-safety of the dynamic linker and
breaks the use of shared locks for the common symbol lookup case. It is
unlikely to provide any benefit for lazy binding or PLT lookups, so
provide equivalent functionality in the non-PLT relocation handling loop
by checking if the symbol used by the current relocation is the same as
the one used during the last lookup. No inter-object cachine is done as
it is also unlikely to be benefical.
Testing with Firefox startup on AMD64 shows a small performance gain by
the new method.

most platforms it just does a simple base-relative fixup; on SPARC it does
nothing.)
* _rtld_relocate_plt_object() does immediate binding for a PLT entry.
The basic gist is that this saves a bit of time on SPARC (where the iteration
through the pltrela table was gratuitous), and a little less time on all other
platforms. A whole lot of #ifdef'ed crap is moved out of reloc.c, too.

Replace COMBREL with just-in-time check in _rtld_relocate_nonplt_objects.
The COMBREL logic predates thread-safety of the dynamic linker and
breaks the use of shared locks for the common symbol lookup case. It is
unlikely to provide any benefit for lazy binding or PLT lookups, so
provide equivalent functionality in the non-PLT relocation handling loop
by checking if the symbol used by the current relocation is the same as
the one used during the last lookup. No inter-object cachine is done as
it is also unlikely to be benefical.
Testing with Firefox startup on AMD64 shows a small performance gain by
the new method.
Drop symbol number from default branch diagnostic, it isn't set at this
point and most likely not valid either.
Expand symnum, GCC's uninitialized used tracking is too imprecise.
Fix C&P bug. Deal with more MIPS hacks overriding def.
Add last_symnum, move up def and defobj.
Add back symnum, fix debug print.
Replace last use of r_type.
Fix indentation.
Fix indentation.

ld.elf_so: New test for extern initial-exec TLS, PR toolchain/50277.
ld.elf_so: Fix extern TLS test to match PR toolchain/50277.
Now it's actually testing the problem.
ld.elf_so: Nix inadvertently committed private test program.
ld.elf_so: Fix set lists for MKDEBUG=yes builds with t_tls_extern.
ld.elf_so: Sprinkle tls debug messages.
ld.elf_so: Make tls alloc debug messages more detailed and greppable.
ld.elf_so: Test variations on PR toolchain/50277.
ld.elf_so: Test extern dynamic TLS too.
ld.elf_so: Factor out logic in TLS tests to make writing more easier.
No functional change intended.
ld.elf_so: Test TLS abuse of static def, dynamic use and vice versa.
ld.elf_so: Shorter test names.
No functional non-cosmetic change intended.
ld.elf_so: Separately test eager and lazy resolution of def tls ptr.
eager: before loading use library
lazy: after loading use library
Add recent ld.elf_so test helpers debug info
ld.elf_so: Add new files to debug/shl.mi.
ld.elf_so: tls_extern dynamic_defabuse_eager must xfail differently.
If a symbol has already been resolved as dynamic TLS, any library
that tries to use it as static TLS cannot be dlopened.
ld.elf_so: Test another edge case of mismatched TLS models.
One library defines a symbol and _doesn't_ use it, so it has no
indication of whether the symbol is for static TLS or dynamic TLS,
and then two other libraries use it in different ways.
ld.elf_so: Test dynamic-then-static abuse via ctor.
ld.elf_so: Fix missing tab in debug/shl.mi in last change.
Fix interactions of initial-exec TLS model and dlopen
(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.
This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.
(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.
(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.
Avoid using uninitialized variable "symnum" when building with DEBUG
enabled by borrowing the rdbg_symname() macro from arch/x86_64.
ld.elf_so: Sprinkle more debug messages on dlopen and error.
PR pkg/57445
Fix MKDEBUGLIB build by adding these installed files to the debug
set list.
One could argue that these files are not of any use, so why install
them? I don't have a good argument either way, and this is (for
now) a simple work-around for PR bin/57455 Please feel free to
commit a different fix to avoid installing these files at all.
Fix markup of libh_ MKDEBUGLIB=yes only files
TLS variant I archs need to fudge the offset by the size of the TCB.
tests/libexec/ld.elf_so: Fix helper library makefiles.
1. Consolidate logic into a single helper.mk to reduce duplication.
2. Set NO* variables, not MK* variables which are reserved for user.
3. Avoid eager X!= in favour of lazy ${X:sh}.
4. Mark _g.a set list entries obsolete. Never should've been built!

Add recent ld.elf_so test helpers debug info
ld.elf_so: Add new files to debug/shl.mi.
ld.elf_so: tls_extern dynamic_defabuse_eager must xfail differently.
If a symbol has already been resolved as dynamic TLS, any library
that tries to use it as static TLS cannot be dlopened.
ld.elf_so: Test another edge case of mismatched TLS models.
One library defines a symbol and _doesn't_ use it, so it has no
indication of whether the symbol is for static TLS or dynamic TLS,
and then two other libraries use it in different ways.
ld.elf_so: Test dynamic-then-static abuse via ctor.
ld.elf_so: Fix missing tab in debug/shl.mi in last change.
Fix interactions of initial-exec TLS model and dlopen
(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.
This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.
(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.
(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.
Avoid using uninitialized variable "symnum" when building with DEBUG
enabled by borrowing the rdbg_symname() macro from arch/x86_64.
ld.elf_so: Sprinkle more debug messages on dlopen and error.

Fix MKDEBUGLIB build by adding these installed files to the debug

One could argue that these files are not of any use, so why install
them? I don't have a good argument either way, and this is (for
now) a simple work-around for PR bin/57455 Please feel free to
commit a different fix to avoid installing these files at all.
Fix markup of libh_ MKDEBUGLIB=yes only files
TLS variant I archs need to fudge the offset by the size of the TCB.

1. Consolidate logic into a single helper.mk to reduce duplication.
2. Set NO* variables, not MK* variables which are reserved for user.
3. Avoid eager X!= in favour of lazy ${X:sh}.
4. Mark _g.a set list entries obsolete. Never should've been built!

joerg | Replace COMBREL with just-in-time check in _rtld_relocate_nonplt_objects.
The COMBREL logic predates thread-safety of the dynamic linker and
breaks the use of shared locks for the common symbol lookup case. It is
unlikely to provide any benefit for lazy binding or PLT lookups, so
provide equivalent functionality in the non-PLT relocation handling loop
by checking if the symbol used by the current relocation is the same as
the one used during the last lookup. No inter-object cachine is done as
it is also unlikely to be benefical.
Testing with Firefox startup on AMD64 shows a small performance gain by
the new method.

Add basic support for indirect functions. It allows providing a public

Refactor calls to functions by address in ld.elf_so to create temporary

- no support for initialising static storage with function pointers
- no support for unnamed resolver functions

mycroft | Split _rtld_relocate_plt_object() into two MD functions:
* _rtld_relocate_plt_lazy() fixes up all the relocs pointing to the PLT. (On
most platforms it just does a simple base-relative fixup; on SPARC it does
nothing.)
* _rtld_relocate_plt_object() does immediate binding for a PLT entry.
The basic gist is that this saves a bit of time on SPARC (where the iteration
through the pltrela table was gratuitous), and a little less time on all other
platforms. A whole lot of #ifdef'ed crap is moved out of reloc.c, too.

PR/39240: Satoshi Suetake: Don't fail when attempting to resolve weak symbols
when we are doing immediate binding, leave them alone and they will be dealt
with later during lazy binding. From skrll@
Implement negative cache checks for symbol lookups.
Uses the Donelist idea from FreeBSD.
Use alloca(3) instead of local xmalloc for creating our DoneLists.
This allows threaded programs to use us a little better, PR lib/43005.

Replace COMBREL with just-in-time check in _rtld_relocate_nonplt_objects.
The COMBREL logic predates thread-safety of the dynamic linker and
breaks the use of shared locks for the common symbol lookup case. It is
unlikely to provide any benefit for lazy binding or PLT lookups, so
provide equivalent functionality in the non-PLT relocation handling loop
by checking if the symbol used by the current relocation is the same as
the one used during the last lookup. No inter-object cachine is done as
it is also unlikely to be benefical.
Testing with Firefox startup on AMD64 shows a small performance gain by
the new method.
Drop symbol number from default branch diagnostic, it isn't set at this
point and most likely not valid either.
Expand symnum, GCC's uninitialized used tracking is too imprecise.
Fix C&P bug. Deal with more MIPS hacks overriding def.
Add last_symnum, move up def and defobj.
Add back symnum, fix debug print.
Replace last use of r_type.
Fix indentation.
Fix indentation.

ld.elf_so: New test for extern initial-exec TLS, PR toolchain/50277.
ld.elf_so: Fix extern TLS test to match PR toolchain/50277.
Now it's actually testing the problem.
ld.elf_so: Nix inadvertently committed private test program.
ld.elf_so: Fix set lists for MKDEBUG=yes builds with t_tls_extern.
ld.elf_so: Sprinkle tls debug messages.
ld.elf_so: Make tls alloc debug messages more detailed and greppable.
ld.elf_so: Test variations on PR toolchain/50277.
ld.elf_so: Test extern dynamic TLS too.
ld.elf_so: Factor out logic in TLS tests to make writing more easier.
No functional change intended.
ld.elf_so: Test TLS abuse of static def, dynamic use and vice versa.
ld.elf_so: Shorter test names.
No functional non-cosmetic change intended.
ld.elf_so: Separately test eager and lazy resolution of def tls ptr.
eager: before loading use library
lazy: after loading use library
Add recent ld.elf_so test helpers debug info
ld.elf_so: Add new files to debug/shl.mi.
ld.elf_so: tls_extern dynamic_defabuse_eager must xfail differently.
If a symbol has already been resolved as dynamic TLS, any library
that tries to use it as static TLS cannot be dlopened.
ld.elf_so: Test another edge case of mismatched TLS models.
One library defines a symbol and _doesn't_ use it, so it has no
indication of whether the symbol is for static TLS or dynamic TLS,
and then two other libraries use it in different ways.
ld.elf_so: Test dynamic-then-static abuse via ctor.
ld.elf_so: Fix missing tab in debug/shl.mi in last change.
Fix interactions of initial-exec TLS model and dlopen
(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.
This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.
(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.
(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.
Avoid using uninitialized variable "symnum" when building with DEBUG
enabled by borrowing the rdbg_symname() macro from arch/x86_64.
ld.elf_so: Sprinkle more debug messages on dlopen and error.
PR pkg/57445
Fix MKDEBUGLIB build by adding these installed files to the debug
set list.
One could argue that these files are not of any use, so why install
them? I don't have a good argument either way, and this is (for
now) a simple work-around for PR bin/57455 Please feel free to
commit a different fix to avoid installing these files at all.
Fix markup of libh_ MKDEBUGLIB=yes only files
TLS variant I archs need to fudge the offset by the size of the TCB.
tests/libexec/ld.elf_so: Fix helper library makefiles.
1. Consolidate logic into a single helper.mk to reduce duplication.
2. Set NO* variables, not MK* variables which are reserved for user.
3. Avoid eager X!= in favour of lazy ${X:sh}.
4. Mark _g.a set list entries obsolete. Never should've been built!

ld.elf_so: New test for extern initial-exec TLS, PR toolchain/50277.
ld.elf_so: Fix extern TLS test to match PR toolchain/50277.
Now it's actually testing the problem.
ld.elf_so: Nix inadvertently committed private test program.
ld.elf_so: Fix set lists for MKDEBUG=yes builds with t_tls_extern.
ld.elf_so: Sprinkle tls debug messages.
ld.elf_so: Make tls alloc debug messages more detailed and greppable.
ld.elf_so: Test variations on PR toolchain/50277.
ld.elf_so: Test extern dynamic TLS too.
ld.elf_so: Factor out logic in TLS tests to make writing more easier.
No functional change intended.
ld.elf_so: Test TLS abuse of static def, dynamic use and vice versa.
ld.elf_so: Shorter test names.
No functional non-cosmetic change intended.
ld.elf_so: Separately test eager and lazy resolution of def tls ptr.
eager: before loading use library
lazy: after loading use library
Add recent ld.elf_so test helpers debug info
ld.elf_so: Add new files to debug/shl.mi.
ld.elf_so: tls_extern dynamic_defabuse_eager must xfail differently.
If a symbol has already been resolved as dynamic TLS, any library
that tries to use it as static TLS cannot be dlopened.
ld.elf_so: Test another edge case of mismatched TLS models.
One library defines a symbol and _doesn't_ use it, so it has no
indication of whether the symbol is for static TLS or dynamic TLS,
and then two other libraries use it in different ways.
ld.elf_so: Test dynamic-then-static abuse via ctor.
ld.elf_so: Fix missing tab in debug/shl.mi in last change.
Fix interactions of initial-exec TLS model and dlopen
(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.
This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.
(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.
(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.
Avoid using uninitialized variable "symnum" when building with DEBUG
enabled by borrowing the rdbg_symname() macro from arch/x86_64.
ld.elf_so: Sprinkle more debug messages on dlopen and error.
PR pkg/57445
Fix MKDEBUGLIB build by adding these installed files to the debug
set list.
XXX
One could argue that these files are not of any use, so why install
them? I don't have a good argument either way, and this is (for
now) a simple work-around for PR bin/57455 Please feel free to
commit a different fix to avoid installing these files at all.
Fix markup of libh_ MKDEBUGLIB=yes only files
TLS variant I archs need to fudge the offset by the size of the TCB.
tests/libexec/ld.elf_so: Fix helper library makefiles.
1. Consolidate logic into a single helper.mk to reduce duplication.
2. Set NO* variables, not MK* variables which are reserved for user.
3. Avoid eager X!= in favour of lazy ${X:sh}.
4. Mark _g.a set list entries obsolete. Never should've been built!

joerg | Rework ifunc support to address a number of short comings:
- Move to a shared _rtld_call_ifunc for rel and rela architectures
- Architectures using rel format must patch IRELATIVE non-PLT
relocations like RELATIVE in additition to the later ifunc handling
- Consistently record the delta to the end of the relocation group for
non-PLT IRELATIVE relocations
Hidden ifunc is now supported on all ifunc platforms, even when using
-fno-plt. The combination of -fno-plt and relro is broken due to
incorrect GNU ld output though.

joerg | Fix interactions of initial-exec TLS model and dlopen
(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.
This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.
(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.
(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.

joerg | branches: 1.41.4; 1.41.12;
Rework ifunc support to address a number of short comings:
- Move to a shared _rtld_call_ifunc for rel and rela architectures
- Architectures using rel format must patch IRELATIVE non-PLT
relocations like RELATIVE in additition to the later ifunc handling
- Consistently record the delta to the end of the relocation group for
non-PLT IRELATIVE relocations
Hidden ifunc is now supported on all ifunc platforms, even when using
-fno-plt. The combination of -fno-plt and relro is broken due to
incorrect GNU ld output though.
|
| 1.40 | 06-Nov-2017 |
joerg | branches: 1.40.2;
init/fini for the main program is handled by crt0.o, so ifunc handling
is skipped right now as it iterates the same list. Don't repeat that
mistake and explicitly take care of it in the dynamic linker.

joerg | Replace COMBREL with just-in-time check in _rtld_relocate_nonplt_objects.
The COMBREL logic predates thread-safety of the dynamic linker and
breaks the use of shared locks for the common symbol lookup case. It is
unlikely to provide any benefit for lazy binding or PLT lookups, so
provide equivalent functionality in the non-PLT relocation handling loop
by checking if the symbol used by the current relocation is the same as
the one used during the last lookup. No inter-object cachine is done as
it is also unlikely to be benefical.
Testing with Firefox startup on AMD64 shows a small performance gain by
the new method.

Refactor calls to functions by address in ld.elf_so to create temporary
function descriptors on the stack, if the address is not leaked outside.
Limitations:

Initialize _rtld_sym_zero.st_value to -_rtld_objself.maprelocbase. Now when
the symbol is resolved, st_value + maprelocbase will equal 0 and the above
check in _rtld_bind will fire and a call to NULL will be avoided.

|

mycroft | Remove the `self' args to _rtld_relocate_objects() and
_rtld_relocate_nonplt_objects().
|

mycroft | Push the _rtld_bind() interface into MD code -- it's just a trivial wrapper
anyway.
|
| 1.15 | 17-Sep-2002 |
junyoung | Make immediate binding work again by actually implementing
_rtld_relocate_plt_objects(). Note that this is for i386 only;
any efforts to make it work on other platforms are left to
those who are using them...
|

mycroft | Nuke -DRTLD_RELOCATE_SELF and `dodebug' from orbit.
|

mycroft | _rtld_bind_start() is not used in MI code, so declare it in the MD code.
|
| 1.12 | 11-Sep-2002 |
mycroft | Split the `self' case out of _rtld_relocate_nonplt_objects, into a new function
_rtld_relocate_nonplt_self(), which is called from _rtld_start.
Now we're completely relocated before main() is called.
We also no longer need _GOT_END_, so junk the ld script.
This code assumes that ld.elf_so only contains RELATIVE relocs, but that's
supposed to be the case for -Bsymbolic anyway.
|
| 1.11 | 11-Sep-2002 |
junyoung | Add $NetBSD$.
|
| 1.10 | 09-Sep-2002 |
mycroft | Get rid of RTLD_RELOCATE_SELF on i386.
* Add a ld.so.script that exports _GOT_END_.
* Prebind the GOT in _rtld_start.
* Skip over GOT relocs in _rtld_relocate_nonplt_objects().
This makes debugging work better at least.
|
| 1.9 | 06-Sep-2002 |
mycroft | Pass down an additional flag to _rtld_relocate_nonplt_objects() which
indicates whether we're relocating ld.elf_so itself. Use this in some places
rather than hackish tests on `dodebug'. (The Alpha and HPPA `dodebug' tests
were actually noops, because RTLD_RELOCATE_SELF is not set, and therefore
dodebug is always true.)
|
| 1.8 | 06-Sep-2002 |
mycroft | Introduce a new flag, `isdynamic', which is used to remember whether the
executable was of type ET_DYN. Use this instead of `mainprog' to determine
whether we need to do base-relative fixups of the PLT. (This allows loading
non-relocatable objects, should we desire to do that at some point...)
|
| 1.7 | 06-Sep-2002 |
mycroft | Re-poison a lot of consts, now that the mark shite is gone.
|
| 1.6 | 06-Sep-2002 |
mycroft | Split _rtld_relocate_plt_object() into two MD functions:
* _rtld_relocate_plt_lazy() fixes up all the relocs pointing to the PLT. (On
most platforms it just does a simple base-relative fixup; on SPARC it does
nothing.)
* _rtld_relocate_plt_object() does immediate binding for a PLT entry.
The basic gist is that this saves a bit of time on SPARC (where the iteration
through the pltrela table was gratuitous), and a little less time on all other
platforms. A whole lot of #ifdef'ed crap is moved out of reloc.c, too.
NOT tested on: hppa sh x86_64
|
| 1.5 | 05-Sep-2002 |
mycroft | Partially fix up some debug printf()s that don't need to use defobj.
|
| 1.4 | 05-Sep-2002 |
mycroft | A few things:
* Pass a symbol number to _rtld_find_symdef(), not a r_info.
* Don't try to do a symbol lookup when we find an unsupported relocation;
instead get the symbol name from the referencing object's strtab.
* Add preliminary support for `-z combreloc'-style startup optimization on
i386, `#ifdef COMBRELOC'.
|
| 1.3 | 05-Sep-2002 |
mycroft | Rename _rtld_relocate_nonplt_object() to _rtld_relocate_nonplt_objects(),
and push the outer loop into it. This actually shaves a couple % off startup
time at least on PCs.
|
| 1.2 | 05-Sep-2002 |
mycroft | Split _rtld_relocate_nonplt_object() into separate MD files.
|
| 1.1 | 05-Sep-2002 |

ld.elf_so: New test for extern initial-exec TLS, PR toolchain/50277.
ld.elf_so: Fix extern TLS test to match PR toolchain/50277.
Now it's actually testing the problem.
ld.elf_so: Nix inadvertently committed private test program.
ld.elf_so: Fix set lists for MKDEBUG=yes builds with t_tls_extern.
ld.elf_so: Sprinkle tls debug messages.
ld.elf_so: Make tls alloc debug messages more detailed and greppable.
ld.elf_so: Test variations on PR toolchain/50277.
ld.elf_so: Test extern dynamic TLS too.
ld.elf_so: Factor out logic in TLS tests to make writing more easier.
No functional change intended.
ld.elf_so: Test TLS abuse of static def, dynamic use and vice versa.
ld.elf_so: Shorter test names.
No functional non-cosmetic change intended.
ld.elf_so: Separately test eager and lazy resolution of def tls ptr.
eager: before loading use library
lazy: after loading use library
Add recent ld.elf_so test helpers debug info
ld.elf_so: Add new files to debug/shl.mi.
ld.elf_so: tls_extern dynamic_defabuse_eager must xfail differently.
If a symbol has already been resolved as dynamic TLS, any library
that tries to use it as static TLS cannot be dlopened.
ld.elf_so: Test another edge case of mismatched TLS models.
One library defines a symbol and _doesn't_ use it, so it has no
indication of whether the symbol is for static TLS or dynamic TLS,
and then two other libraries use it in different ways.
ld.elf_so: Test dynamic-then-static abuse via ctor.
ld.elf_so: Fix missing tab in debug/shl.mi in last change.
Fix interactions of initial-exec TLS model and dlopen
(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.
This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.
(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.
(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.
Avoid using uninitialized variable "symnum" when building with DEBUG
enabled by borrowing the rdbg_symname() macro from arch/x86_64.
ld.elf_so: Sprinkle more debug messages on dlopen and error.
PR pkg/57445
Fix MKDEBUGLIB build by adding these installed files to the debug
set list.
XXX
One could argue that these files are not of any use, so why install
them? I don't have a good argument either way, and this is (for
now) a simple work-around for PR bin/57455 Please feel free to
commit a different fix to avoid installing these files at all.
Fix markup of libh_ MKDEBUGLIB=yes only files
TLS variant I archs need to fudge the offset by the size of the TCB.
tests/libexec/ld.elf_so: Fix helper library makefiles.
1. Consolidate logic into a single helper.mk to reduce duplication.
2. Set NO* variables, not MK* variables which are reserved for user.
3. Avoid eager X!= in favour of lazy ${X:sh}.
4. Mark _g.a set list entries obsolete. Never should've been built!

Fix interactions of initial-exec TLS model and dlopen
(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.
This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.
(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.
(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.

Add IRELATIVE support for ARM, X86 and PowerPC.
|
| 1.32 | 19-Jun-2017 |
joerg | Replace COMBREL with just-in-time check in _rtld_relocate_nonplt_objects.
The COMBREL logic predates thread-safety of the dynamic linker and
breaks the use of shared locks for the common symbol lookup case. It is
unlikely to provide any benefit for lazy binding or PLT lookups, so
provide equivalent functionality in the non-PLT relocation handling loop
by checking if the symbol used by the current relocation is the same as
the one used during the last lookup. No inter-object cachine is done as
it is also unlikely to be benefical.
Testing with Firefox startup on AMD64 shows a small performance gain by
the new method.

joerg | Add basic support for indirect functions. It allows providing a public
function symbol with an implementation choosen at run time.
Refactor calls to functions by address in ld.elf_so to create temporary
function descriptors on the stack, if the address is not leaked outside.
Limitations:
- no support for initialising static storage with function pointers
- no support for unnamed resolver functions

act like the other versions.
In _rtld_bind, if the result is 0, call _rtld_die.
Initialize _rtld_sym_zero.st_value to -_rtld_objself.maprelocbase. Now when
the symbol is resolved, st_value + maprelocbase will equal 0 and the above
check in _rtld_bind will fire and a call to NULL will be avoided.

_rtld_relocate_nonplt_objects().

anyway.

junyoung | Add $NetBSD$.
|
| 1.9 | 06-Sep-2002 |
mycroft | Pass down an additional flag to _rtld_relocate_nonplt_objects() which
indicates whether we're relocating ld.elf_so itself. Use this in some places
rather than hackish tests on `dodebug'. (The Alpha and HPPA `dodebug' tests
were actually noops, because RTLD_RELOCATE_SELF is not set, and therefore
dodebug is always true.)
|
| 1.8 | 06-Sep-2002 |
mycroft | Introduce a new flag, `isdynamic', which is used to remember whether the
executable was of type ET_DYN. Use this instead of `mainprog' to determine
whether we need to do base-relative fixups of the PLT. (This allows loading
non-relocatable objects, should we desire to do that at some point...)
|
| 1.7 | 06-Sep-2002 |
mycroft | Re-poison a lot of consts, now that the mark shite is gone.
|
| 1.6 | 06-Sep-2002 |
mycroft | Split _rtld_relocate_plt_object() into two MD functions:
* _rtld_relocate_plt_lazy() fixes up all the relocs pointing to the PLT. (On
most platforms it just does a simple base-relative fixup; on SPARC it does
nothing.)
* _rtld_relocate_plt_object() does immediate binding for a PLT entry.
The basic gist is that this saves a bit of time on SPARC (where the iteration
through the pltrela table was gratuitous), and a little less time on all other
platforms. A whole lot of #ifdef'ed crap is moved out of reloc.c, too.
NOT tested on: hppa sh x86_64

mycroft | A few things:
* Pass a symbol number to _rtld_find_symdef(), not a r_info.
* Don't try to do a symbol lookup when we find an unsupported relocation;
instead get the symbol name from the referencing object's strtab.
* Add preliminary support for `-z combreloc'-style startup optimization on
i386, `#ifdef COMBRELOC'.
|
| 1.3 | 05-Sep-2002 |
mycroft | Rename _rtld_relocate_nonplt_object() to _rtld_relocate_nonplt_objects(),
and push the outer loop into it. This actually shaves a couple % off startup
time at least on PCs.

ld.elf_so: New test for extern initial-exec TLS, PR toolchain/50277.
ld.elf_so: Fix extern TLS test to match PR toolchain/50277.
Now it's actually testing the problem.
ld.elf_so: Nix inadvertently committed private test program.
ld.elf_so: Fix set lists for MKDEBUG=yes builds with t_tls_extern.
ld.elf_so: Sprinkle tls debug messages.
ld.elf_so: Make tls alloc debug messages more detailed and greppable.
ld.elf_so: Test variations on PR toolchain/50277.
ld.elf_so: Test extern dynamic TLS too.
ld.elf_so: Factor out logic in TLS tests to make writing more easier.
No functional change intended.
ld.elf_so: Test TLS abuse of static def, dynamic use and vice versa.
ld.elf_so: Shorter test names.
No functional non-cosmetic change intended.
ld.elf_so: Separately test eager and lazy resolution of def tls ptr.
eager: before loading use library
lazy: after loading use library
Add recent ld.elf_so test helpers debug info
ld.elf_so: Add new files to debug/shl.mi.
ld.elf_so: tls_extern dynamic_defabuse_eager must xfail differently.
If a symbol has already been resolved as dynamic TLS, any library
that tries to use it as static TLS cannot be dlopened.
ld.elf_so: Test another edge case of mismatched TLS models.
One library defines a symbol and _doesn't_ use it, so it has no
indication of whether the symbol is for static TLS or dynamic TLS,
and then two other libraries use it in different ways.
ld.elf_so: Test dynamic-then-static abuse via ctor.
ld.elf_so: Fix missing tab in debug/shl.mi in last change.
Fix interactions of initial-exec TLS model and dlopen
(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.
This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.
(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.
(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.
Avoid using uninitialized variable "symnum" when building with DEBUG
enabled by borrowing the rdbg_symname() macro from arch/x86_64.
ld.elf_so: Sprinkle more debug messages on dlopen and error.
PR pkg/57445
Fix MKDEBUGLIB build by adding these installed files to the debug
set list.
XXX
One could argue that these files are not of any use, so why install
them? I don't have a good argument either way, and this is (for
now) a simple work-around for PR bin/57455 Please feel free to
commit a different fix to avoid installing these files at all.
Fix markup of libh_ MKDEBUGLIB=yes only files
TLS variant I archs need to fudge the offset by the size of the TCB.
tests/libexec/ld.elf_so: Fix helper library makefiles.
1. Consolidate logic into a single helper.mk to reduce duplication.
2. Set NO* variables, not MK* variables which are reserved for user.
3. Avoid eager X!= in favour of lazy ${X:sh}.
4. Mark _g.a set list entries obsolete. Never should've been built!

Fix interactions of initial-exec TLS model and dlopen
(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.
This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.
(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.
(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.

The COMBREL logic predates thread-safety of the dynamic linker and
breaks the use of shared locks for the common symbol lookup case. It is
unlikely to provide any benefit for lazy binding or PLT lookups, so
provide equivalent functionality in the non-PLT relocation handling loop
by checking if the symbol used by the current relocation is the same as
the one used during the last lookup. No inter-object cachine is done as
it is also unlikely to be benefical.
Testing with Firefox startup on AMD64 shows a small performance gain by
the new method.

mycroft | Resolve the GOT before doing relocations. Then, when doing relocations, for
symbols in the global part of the symbol table, use the updated GOT entry
rather than doing a lookup. (This provides the same effect as `-z combreloc'
on other platforms -- at most one lookup is done per symbol.)
Unfortunately, it is necessary to turn off lazy binding on MIPS. As the
comment says:
* XXX DANGER WILL ROBINSON!
* You might think this is stupid, as it intentionally
* defeats lazy binding -- and you'd be right.
* Unfortunately, for lazy binding to work right, we
* need to a way to force the GOT slots used for
* function pointers to be resolved immediately. This
* is supposed to be done automatically by the linker,
* by not outputting a PLT slot and setting st_value
* to 0, but GNU ld does not do so reliably.

mycroft | Snapshot of work to make MIPS ld.elf_so relocatable.
|
| 1.16 | 06-Sep-2002 |
mycroft | Pass down an additional flag to _rtld_relocate_nonplt_objects() which
indicates whether we're relocating ld.elf_so itself. Use this in some places
rather than hackish tests on `dodebug'. (The Alpha and HPPA `dodebug' tests
were actually noops, because RTLD_RELOCATE_SELF is not set, and therefore
dodebug is always true.)
|
| 1.15 | 06-Sep-2002 |
mycroft | Introduce a new flag, `isdynamic', which is used to remember whether the
executable was of type ET_DYN. Use this instead of `mainprog' to determine
whether we need to do base-relative fixups of the PLT. (This allows loading
non-relocatable objects, should we desire to do that at some point...)
|

|
| 1.12 | 06-Sep-2002 |
mycroft | Split _rtld_relocate_plt_object() into two MD functions:
* _rtld_relocate_plt_lazy() fixes up all the relocs pointing to the PLT. (On
most platforms it just does a simple base-relative fixup; on SPARC it does
nothing.)
* _rtld_relocate_plt_object() does immediate binding for a PLT entry.
The basic gist is that this saves a bit of time on SPARC (where the iteration
through the pltrela table was gratuitous), and a little less time on all other
platforms. A whole lot of #ifdef'ed crap is moved out of reloc.c, too.

* Don't try to do a symbol lookup when we find an unsupported relocation;
instead get the symbol name from the referencing object's strtab.
* Add preliminary support for `-z combreloc'-style startup optimization on
i386, `#ifdef COMBRELOC'.

Replace COMBREL with just-in-time check in _rtld_relocate_nonplt_objects.
The COMBREL logic predates thread-safety of the dynamic linker and
breaks the use of shared locks for the common symbol lookup case. It is
unlikely to provide any benefit for lazy binding or PLT lookups, so
provide equivalent functionality in the non-PLT relocation handling loop
by checking if the symbol used by the current relocation is the same as
the one used during the last lookup. No inter-object cachine is done as
it is also unlikely to be benefical.
Testing with Firefox startup on AMD64 shows a small performance gain by
the new method.
Drop symbol number from default branch diagnostic, it isn't set at this
point and most likely not valid either.
Expand symnum, GCC's uninitialized used tracking is too imprecise.
Fix C&P bug. Deal with more MIPS hacks overriding def.
Add last_symnum, move up def and defobj.
Add back symnum, fix debug print.
Replace last use of r_type.
Fix indentation.
Fix indentation.

ld.elf_so: New test for extern initial-exec TLS, PR toolchain/50277.

ld.elf_so: Test TLS abuse of static def, dynamic use and vice versa.
ld.elf_so: Shorter test names.
No functional non-cosmetic change intended.
ld.elf_so: Separately test eager and lazy resolution of def tls ptr.
eager: before loading use library
lazy: after loading use library
Add recent ld.elf_so test helpers debug info
ld.elf_so: Add new files to debug/shl.mi.
ld.elf_so: tls_extern dynamic_defabuse_eager must xfail differently.
If a symbol has already been resolved as dynamic TLS, any library
that tries to use it as static TLS cannot be dlopened.
ld.elf_so: Test another edge case of mismatched TLS models.
One library defines a symbol and _doesn't_ use it, so it has no
indication of whether the symbol is for static TLS or dynamic TLS,
and then two other libraries use it in different ways.
ld.elf_so: Test dynamic-then-static abuse via ctor.
ld.elf_so: Fix missing tab in debug/shl.mi in last change.
Fix interactions of initial-exec TLS model and dlopen
(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.
This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.
(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.
(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.
Avoid using uninitialized variable "symnum" when building with DEBUG
enabled by borrowing the rdbg_symname() macro from arch/x86_64.
ld.elf_so: Sprinkle more debug messages on dlopen and error.
PR pkg/57445
Fix MKDEBUGLIB build by adding these installed files to the debug
set list.
One could argue that these files are not of any use, so why install
them? I don't have a good argument either way, and this is (for
now) a simple work-around for PR bin/57455 Please feel free to
commit a different fix to avoid installing these files at all.
Fix markup of libh_ MKDEBUGLIB=yes only files
TLS variant I archs need to fudge the offset by the size of the TCB.
tests/libexec/ld.elf_so: Fix helper library makefiles.
1. Consolidate logic into a single helper.mk to reduce duplication.
2. Set NO* variables, not MK* variables which are reserved for user.
3. Avoid eager X!= in favour of lazy ${X:sh}.
4. Mark _g.a set list entries obsolete. Never should've been built!

Fix interactions of initial-exec TLS model and dlopen
(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.
This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.
(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.
(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.

The COMBREL logic predates thread-safety of the dynamic linker and

unlikely to provide any benefit for lazy binding or PLT lookups, so
provide equivalent functionality in the non-PLT relocation handling loop
by checking if the symbol used by the current relocation is the same as
the one used during the last lookup. No inter-object cachine is done as
it is also unlikely to be benefical.
Testing with Firefox startup on AMD64 shows a small performance gain by
the new method.

ld.elf_so: Test another edge case of mismatched TLS models.
One library defines a symbol and _doesn't_ use it, so it has no

and then two other libraries use it in different ways.

ld.elf_so: Fix missing tab in debug/shl.mi in last change.
Fix interactions of initial-exec TLS model and dlopen
(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.
This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.
(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.
(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.
Avoid using uninitialized variable "symnum" when building with DEBUG
enabled by borrowing the rdbg_symname() macro from arch/x86_64.

ld.elf_so: New test for extern initial-exec TLS, PR toolchain/50277.

ld.elf_so: Test TLS abuse of static def, dynamic use and vice versa.
ld.elf_so: Shorter test names.

eager: before loading use library
lazy: after loading use library
Add recent ld.elf_so test helpers debug info
ld.elf_so: Add new files to debug/shl.mi.
ld.elf_so: tls_extern dynamic_defabuse_eager must xfail differently.
If a symbol has already been resolved as dynamic TLS, any library
that tries to use it as static TLS cannot be dlopened.
ld.elf_so: Test another edge case of mismatched TLS models.
One library defines a symbol and _doesn't_ use it, so it has no
indication of whether the symbol is for static TLS or dynamic TLS,
and then two other libraries use it in different ways.
ld.elf_so: Test dynamic-then-static abuse via ctor.
ld.elf_so: Fix missing tab in debug/shl.mi in last change.
Fix interactions of initial-exec TLS model and dlopen
(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.
This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.
(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.
(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.
Avoid using uninitialized variable "symnum" when building with DEBUG
enabled by borrowing the rdbg_symname() macro from arch/x86_64.
ld.elf_so: Sprinkle more debug messages on dlopen and error.

commit a different fix to avoid installing these files at all.
Fix markup of libh_ MKDEBUGLIB=yes only files
TLS variant I archs need to fudge the offset by the size of the TCB.

1. Consolidate logic into a single helper.mk to reduce duplication.
2. Set NO* variables, not MK* variables which are reserved for user.
3. Avoid eager X!= in favour of lazy ${X:sh}.
4. Mark _g.a set list entries obsolete. Never should've been built!

The COMBREL logic predates thread-safety of the dynamic linker and
breaks the use of shared locks for the common symbol lookup case. It is
unlikely to provide any benefit for lazy binding or PLT lookups, so
provide equivalent functionality in the non-PLT relocation handling loop
by checking if the symbol used by the current relocation is the same as
the one used during the last lookup. No inter-object cachine is done as
it is also unlikely to be benefical.

the new method.

skrll | Support immediate PLT binding on powerpc. Thanks to Simon Burge for
testing.
I can see the finish line...
|
| 1.35 | 24-Jul-2003 |
skrll | branches: 1.35.6;
ANSIfy and de-__P().
|
| 1.34 | 21-Feb-2003 |
mycroft | Revert previous change.
|
| 1.33 | 11-Jan-2003 |
matt | Fix bug where only 2/3 of the PLT was being synched with the icache.
PLT entries are 12 bytes. Add a #define for that and replace the
explicit values with the PLT_ENTRY_SIZE. This bug can cause random
SIGILL signals to happen.
|
| 1.32 | 05-Oct-2002 |
mycroft | Minor cleanup.
|
| 1.31 | 26-Sep-2002 |
mycroft | Remove the `self' args to _rtld_relocate_objects() and
_rtld_relocate_nonplt_objects().
|
| 1.30 | 26-Sep-2002 |
mycroft | Update a comment.
|
| 1.29 | 26-Sep-2002 |
mycroft | Add a rdbg() in _rtld_bind().
|
| 1.28 | 25-Sep-2002 |
mycroft | Make this work with PLTs larger than 8192 entries (64KB). Not tested
exhaustively, but it works in some simple cases.
|
| 1.27 | 25-Sep-2002 |
mycroft | Push the _rtld_bind() interface into MD code -- it's just a trivial wrapper
anyway.
|
| 1.26 | 24-Sep-2002 |
mycroft | Ignore JMP_SLOT relocs when doing non-PLT relocations. The relalim trimming
hack doesn't always work, because ld(1) sometimes puts the sections in the
wrong order.
|
| 1.25 | 12-Sep-2002 |
mycroft | Remove one more `dodebug' argument.
|
| 1.24 | 12-Sep-2002 |
mycroft | Nuke -DRTLD_RELOCATE_SELF and `dodebug' from orbit.
|
| 1.23 | 12-Sep-2002 |
mycroft | _rtld_bind_start() is not used in MI code, so declare it in the MD code.
|
| 1.22 | 11-Sep-2002 |
mycroft | Implement _rtld_relocate_nonplt_self() here.
|
| 1.21 | 06-Sep-2002 |
mycroft | Pass down an additional flag to _rtld_relocate_nonplt_objects() which
indicates whether we're relocating ld.elf_so itself. Use this in some places
rather than hackish tests on `dodebug'. (The Alpha and HPPA `dodebug' tests
were actually noops, because RTLD_RELOCATE_SELF is not set, and therefore
dodebug is always true.)
|
| 1.20 | 06-Sep-2002 |
mycroft | Introduce a new flag, `isdynamic', which is used to remember whether the
executable was of type ET_DYN. Use this instead of `mainprog' to determine
whether we need to do base-relative fixups of the PLT. (This allows loading
non-relocatable objects, should we desire to do that at some point...)
|
| 1.19 | 06-Sep-2002 |
mycroft | More const poisoning. Now the entire _rtld_bind() path useds a const Obj_Entry.
|
| 1.18 | 06-Sep-2002 |
mycroft | Re-poison a lot of consts, now that the mark shite is gone.
|
| 1.17 | 06-Sep-2002 |
mycroft | Split _rtld_relocate_plt_object() into two MD functions:
* _rtld_relocate_plt_lazy() fixes up all the relocs pointing to the PLT. (On
most platforms it just does a simple base-relative fixup; on SPARC it does
nothing.)
* _rtld_relocate_plt_object() does immediate binding for a PLT entry.
The basic gist is that this saves a bit of time on SPARC (where the iteration
through the pltrela table was gratuitous), and a little less time on all other
platforms. A whole lot of #ifdef'ed crap is moved out of reloc.c, too.
NOT tested on: hppa sh x86_64
|
| 1.16 | 05-Sep-2002 |
mycroft | Partially fix up some debug printf()s that don't need to use defobj.
|
| 1.15 | 05-Sep-2002 |
mycroft | A few things:
* Pass a symbol number to _rtld_find_symdef(), not a r_info.
* Don't try to do a symbol lookup when we find an unsupported relocation;
instead get the symbol name from the referencing object's strtab.
* Add preliminary support for `-z combreloc'-style startup optimization on
i386, `#ifdef COMBRELOC'.
|
| 1.14 | 05-Sep-2002 |
mycroft | Rename _rtld_relocate_nonplt_object() to _rtld_relocate_nonplt_objects(),
and push the outer loop into it. This actually shaves a couple % off startup
time at least on PCs.
|
| 1.13 | 05-Sep-2002 |
mycroft | Split _rtld_relocate_nonplt_object() into separate MD files.
|
| 1.12 | 05-Sep-2002 |
junyoung | Remove unused arguments of _rtld_find_symdef().
|
| 1.11 | 05-Sep-2002 |
mycroft | Make _rtld_setup_pltgot() a consistent interface on all platforms.
|
| 1.10 | 10-Sep-2001 |
mycroft | branches: 1.10.2;
Reorganize PowerPC cold a little. The return value from _rtld_bind_pltgot()
was ambiguous in the case of a weak symbol that was not defined. This caused
RTLD_NOW to fail badly with shared libraries linked against the new crtbegin.o.
|

kleink | Sync with <sys/exec_elf.h> rev. 1.45: ElfNN_RelA -> ElfNN_Rela.

ok, the change from rev 1.33 was unnecessary after all,
only the second part of the previous revision was needed.
put the logic for the initial icache invalidation of the PLT
back the way it was, but in a way that makes clearer what's going on,
and add some comments explaining it.

Replace COMBREL with just-in-time check in _rtld_relocate_nonplt_objects.
The COMBREL logic predates thread-safety of the dynamic linker and
breaks the use of shared locks for the common symbol lookup case. It is
unlikely to provide any benefit for lazy binding or PLT lookups, so
provide equivalent functionality in the non-PLT relocation handling loop
by checking if the symbol used by the current relocation is the same as
the one used during the last lookup. No inter-object cachine is done as
it is also unlikely to be benefical.
Testing with Firefox startup on AMD64 shows a small performance gain by
the new method.
Drop symbol number from default branch diagnostic, it isn't set at this
point and most likely not valid either.
Expand symnum, GCC's uninitialized used tracking is too imprecise.
Fix C&P bug. Deal with more MIPS hacks overriding def.
Add last_symnum, move up def and defobj.
Add back symnum, fix debug print.
Replace last use of r_type.
Fix indentation.

and then two other libraries use it in different ways.

Fix interactions of initial-exec TLS model and dlopen
(1) If an initial-exec relocation was used for a non-local symbol

computation of the static TLS offset used the wrong DSO.
This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.
(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.
(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.

"Replace COMBREL with just-in-time check in _rtld_relocate_nonplt_objects."

joerg | Replace COMBREL with just-in-time check in _rtld_relocate_nonplt_objects.
The COMBREL logic predates thread-safety of the dynamic linker and
breaks the use of shared locks for the common symbol lookup case. It is
unlikely to provide any benefit for lazy binding or PLT lookups, so
provide equivalent functionality in the non-PLT relocation handling loop
by checking if the symbol used by the current relocation is the same as
the one used during the last lookup. No inter-object cachine is done as
it is also unlikely to be benefical.
Testing with Firefox startup on AMD64 shows a small performance gain by
the new method.

Drop symbol number from default branch diagnostic, it isn't set at this
point and most likely not valid either.
Expand symnum, GCC's uninitialized used tracking is too imprecise.
Fix C&P bug. Deal with more MIPS hacks overriding def.
Add last_symnum, move up def and defobj.
Add back symnum, fix debug print.
Replace last use of r_type.
Fix indentation.

ld.elf_so: New test for extern initial-exec TLS, PR toolchain/50277.
ld.elf_so: Fix extern TLS test to match PR toolchain/50277.
Now it's actually testing the problem.
ld.elf_so: Nix inadvertently committed private test program.
ld.elf_so: Fix set lists for MKDEBUG=yes builds with t_tls_extern.
ld.elf_so: Sprinkle tls debug messages.
ld.elf_so: Make tls alloc debug messages more detailed and greppable.
ld.elf_so: Test variations on PR toolchain/50277.
ld.elf_so: Test extern dynamic TLS too.
ld.elf_so: Factor out logic in TLS tests to make writing more easier.
No functional change intended.
ld.elf_so: Test TLS abuse of static def, dynamic use and vice versa.
ld.elf_so: Shorter test names.
No functional non-cosmetic change intended.
ld.elf_so: Separately test eager and lazy resolution of def tls ptr.
eager: before loading use library
lazy: after loading use library
Add recent ld.elf_so test helpers debug info
ld.elf_so: Add new files to debug/shl.mi.
ld.elf_so: tls_extern dynamic_defabuse_eager must xfail differently.
If a symbol has already been resolved as dynamic TLS, any library
that tries to use it as static TLS cannot be dlopened.
ld.elf_so: Test another edge case of mismatched TLS models.
One library defines a symbol and _doesn't_ use it, so it has no
indication of whether the symbol is for static TLS or dynamic TLS,
and then two other libraries use it in different ways.
ld.elf_so: Test dynamic-then-static abuse via ctor.
ld.elf_so: Fix missing tab in debug/shl.mi in last change.
Fix interactions of initial-exec TLS model and dlopen
(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.
This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.
(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.
(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.
Avoid using uninitialized variable "symnum" when building with DEBUG
enabled by borrowing the rdbg_symname() macro from arch/x86_64.
ld.elf_so: Sprinkle more debug messages on dlopen and error.
PR pkg/57445
Fix MKDEBUGLIB build by adding these installed files to the debug
set list.
One could argue that these files are not of any use, so why install
them? I don't have a good argument either way, and this is (for
now) a simple work-around for PR bin/57455 Please feel free to
commit a different fix to avoid installing these files at all.
Fix markup of libh_ MKDEBUGLIB=yes only files
TLS variant I archs need to fudge the offset by the size of the TCB.
tests/libexec/ld.elf_so: Fix helper library makefiles.
1. Consolidate logic into a single helper.mk to reduce duplication.
2. Set NO* variables, not MK* variables which are reserved for user.
3. Avoid eager X!= in favour of lazy ${X:sh}.
4. Mark _g.a set list entries obsolete. Never should've been built!

Add recent ld.elf_so test helpers debug info
ld.elf_so: Add new files to debug/shl.mi.
ld.elf_so: tls_extern dynamic_defabuse_eager must xfail differently.
If a symbol has already been resolved as dynamic TLS, any library
that tries to use it as static TLS cannot be dlopened.
ld.elf_so: Test another edge case of mismatched TLS models.
One library defines a symbol and _doesn't_ use it, so it has no
indication of whether the symbol is for static TLS or dynamic TLS,
and then two other libraries use it in different ways.
ld.elf_so: Test dynamic-then-static abuse via ctor.
ld.elf_so: Fix missing tab in debug/shl.mi in last change.
Fix interactions of initial-exec TLS model and dlopen
(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.
This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.
(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.
(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.
Avoid using uninitialized variable "symnum" when building with DEBUG
enabled by borrowing the rdbg_symname() macro from arch/x86_64.
ld.elf_so: Sprinkle more debug messages on dlopen and error.

Fix MKDEBUGLIB build by adding these installed files to the debug

XXX
One could argue that these files are not of any use, so why install
them? I don't have a good argument either way, and this is (for
now) a simple work-around for PR bin/57455 Please feel free to
commit a different fix to avoid installing these files at all.
Fix markup of libh_ MKDEBUGLIB=yes only files
TLS variant I archs need to fudge the offset by the size of the TCB.

1. Consolidate logic into a single helper.mk to reduce duplication.
2. Set NO* variables, not MK* variables which are reserved for user.
3. Avoid eager X!= in favour of lazy ${X:sh}.
4. Mark _g.a set list entries obsolete. Never should've been built!

mycroft | Split _rtld_relocate_plt_object() into two MD functions:
* _rtld_relocate_plt_lazy() fixes up all the relocs pointing to the PLT. (On
most platforms it just does a simple base-relative fixup; on SPARC it does
nothing.)
* _rtld_relocate_plt_object() does immediate binding for a PLT entry.
The basic gist is that this saves a bit of time on SPARC (where the iteration
through the pltrela table was gratuitous), and a little less time on all other
platforms. A whole lot of #ifdef'ed crap is moved out of reloc.c, too.

i386, `#ifdef COMBRELOC'.

lazy: after loading use library
Add recent ld.elf_so test helpers debug info
ld.elf_so: Add new files to debug/shl.mi.
ld.elf_so: tls_extern dynamic_defabuse_eager must xfail differently.
If a symbol has already been resolved as dynamic TLS, any library
that tries to use it as static TLS cannot be dlopened.
ld.elf_so: Test another edge case of mismatched TLS models.
One library defines a symbol and _doesn't_ use it, so it has no
indication of whether the symbol is for static TLS or dynamic TLS,
and then two other libraries use it in different ways.
ld.elf_so: Test dynamic-then-static abuse via ctor.
ld.elf_so: Fix missing tab in debug/shl.mi in last change.
Fix interactions of initial-exec TLS model and dlopen
(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.
This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.
(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.
(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.
Avoid using uninitialized variable "symnum" when building with DEBUG
enabled by borrowing the rdbg_symname() macro from arch/x86_64.
ld.elf_so: Sprinkle more debug messages on dlopen and error.
PR pkg/57445
Fix MKDEBUGLIB build by adding these installed files to the debug

XXX
One could argue that these files are not of any use, so why install
them? I don't have a good argument either way, and this is (for
now) a simple work-around for PR bin/57455 Please feel free to
commit a different fix to avoid installing these files at all.
Fix markup of libh_ MKDEBUGLIB=yes only files
TLS variant I archs need to fudge the offset by the size of the TCB.

1. Consolidate logic into a single helper.mk to reduce duplication.
2. Set NO* variables, not MK* variables which are reserved for user.
3. Avoid eager X!= in favour of lazy ${X:sh}.
4. Mark _g.a set list entries obsolete. Never should've been built!

joerg | Rework ifunc support to address a number of short comings:
- Move to a shared _rtld_call_ifunc for rel and rela architectures
- Architectures using rel format must patch IRELATIVE non-PLT
relocations like RELATIVE in additition to the later ifunc handling
- Consistently record the delta to the end of the relocation group for
non-PLT IRELATIVE relocations
Hidden ifunc is now supported on all ifunc platforms, even when using
-fno-plt. The combination of -fno-plt and relro is broken due to
incorrect GNU ld output though.

move the defines for RTLD_ARCH_SUBDIR into a sub-sub-makefile so we can
grab these values via reach-over more easily.
some fixes for PR#40170:
- set NATIVE=yes in the environment for genscripts.sh
- set LIB_PATH to /usr/lib/{sparc,i386} for those scripts
- set use_sysroot to "yes", to enable LIB_PATH to work in genscripts.sh
- get rid of building an a.out-happy ldd (but keep supporting a.out
binaries for the ELF version.)
- convert a.out, elf32 and elf64 support into convience libraries and
link them right ones in. if elf_ldd() fails on 64 bit platforms,
try elf32_ldd() before aout_ldd().
now ldd on 64 bit platforms works for 32 bit binaries, aka PR#40199,
and it seems that all the issues from README are gone too.
add some (uintptr_t) to some casts, so these compile with ELFSIZE=32
*and _LP64. necessary for 32/64 bit combo ldd support.
- rework this a bunch to make it work inside /rescue/ldd.
- fix alpha build.

joerg | Fix interactions of initial-exec TLS model and dlopen
(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.
This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.
(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.
(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.

- Architectures using rel format must patch IRELATIVE non-PLT
relocations like RELATIVE in additition to the later ifunc handling
- Consistently record the delta to the end of the relocation group for

Hidden ifunc is now supported on all ifunc platforms, even when using

incorrect GNU ld output though.

joerg | Replace COMBREL with just-in-time check in _rtld_relocate_nonplt_objects.
The COMBREL logic predates thread-safety of the dynamic linker and
breaks the use of shared locks for the common symbol lookup case. It is
unlikely to provide any benefit for lazy binding or PLT lookups, so
provide equivalent functionality in the non-PLT relocation handling loop
by checking if the symbol used by the current relocation is the same as
the one used during the last lookup. No inter-object cachine is done as
it is also unlikely to be benefical.
Testing with Firefox startup on AMD64 shows a small performance gain by
the new method.

* _rtld_relocate_plt_lazy() fixes up all the relocs pointing to the PLT. (On
most platforms it just does a simple base-relative fixup; on SPARC it does
nothing.)
* _rtld_relocate_plt_object() does immediate binding for a PLT entry.
The basic gist is that this saves a bit of time on SPARC (where the iteration
through the pltrela table was gratuitous), and a little less time on all other
platforms. A whole lot of #ifdef'ed crap is moved out of reloc.c, too.

* Add preliminary support for `-z combreloc'-style startup optimization on
i386, `#ifdef COMBRELOC'.

Replace COMBREL with just-in-time check in _rtld_relocate_nonplt_objects.
The COMBREL logic predates thread-safety of the dynamic linker and
breaks the use of shared locks for the common symbol lookup case. It is
unlikely to provide any benefit for lazy binding or PLT lookups, so
provide equivalent functionality in the non-PLT relocation handling loop
by checking if the symbol used by the current relocation is the same as
the one used during the last lookup. No inter-object cachine is done as
it is also unlikely to be benefical.
Testing with Firefox startup on AMD64 shows a small performance gain by
the new method.
Drop symbol number from default branch diagnostic, it isn't set at this
point and most likely not valid either.
Expand symnum, GCC's uninitialized used tracking is too imprecise.
Fix C&P bug. Deal with more MIPS hacks overriding def.
Add last_symnum, move up def and defobj.
Add back symnum, fix debug print.
Replace last use of r_type.
Fix indentation.
Fix indentation.

ld.elf_so: Nix inadvertently committed private test program.
ld.elf_so: Fix set lists for MKDEBUG=yes builds with t_tls_extern.
ld.elf_so: Sprinkle tls debug messages.
ld.elf_so: Make tls alloc debug messages more detailed and greppable.
ld.elf_so: Test variations on PR toolchain/50277.
ld.elf_so: Test extern dynamic TLS too.
ld.elf_so: Factor out logic in TLS tests to make writing more easier.
No functional change intended.
ld.elf_so: Test TLS abuse of static def, dynamic use and vice versa.
ld.elf_so: Shorter test names.
No functional non-cosmetic change intended.
ld.elf_so: Separately test eager and lazy resolution of def tls ptr.
eager: before loading use library
lazy: after loading use library
Add recent ld.elf_so test helpers debug info
ld.elf_so: Add new files to debug/shl.mi.
ld.elf_so: tls_extern dynamic_defabuse_eager must xfail differently.
If a symbol has already been resolved as dynamic TLS, any library
that tries to use it as static TLS cannot be dlopened.
ld.elf_so: Test another edge case of mismatched TLS models.
One library defines a symbol and _doesn't_ use it, so it has no
indication of whether the symbol is for static TLS or dynamic TLS,
and then two other libraries use it in different ways.
ld.elf_so: Test dynamic-then-static abuse via ctor.
ld.elf_so: Fix missing tab in debug/shl.mi in last change.
Fix interactions of initial-exec TLS model and dlopen
(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.
This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.
(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.
(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.
Avoid using uninitialized variable "symnum" when building with DEBUG
enabled by borrowing the rdbg_symname() macro from arch/x86_64.
ld.elf_so: Sprinkle more debug messages on dlopen and error.
PR pkg/57445
Fix MKDEBUGLIB build by adding these installed files to the debug
set list.
XXX
One could argue that these files are not of any use, so why install
them? I don't have a good argument either way, and this is (for
now) a simple work-around for PR bin/57455 Please feel free to
commit a different fix to avoid installing these files at all.
Fix markup of libh_ MKDEBUGLIB=yes only files
TLS variant I archs need to fudge the offset by the size of the TCB.
tests/libexec/ld.elf_so: Fix helper library makefiles.
1. Consolidate logic into a single helper.mk to reduce duplication.
2. Set NO* variables, not MK* variables which are reserved for user.
3. Avoid eager X!= in favour of lazy ${X:sh}.
4. Mark _g.a set list entries obsolete. Never should've been built!

ld.elf_so: Add new files to debug/shl.mi.
ld.elf_so: tls_extern dynamic_defabuse_eager must xfail differently.
If a symbol has already been resolved as dynamic TLS, any library
that tries to use it as static TLS cannot be dlopened.
ld.elf_so: Test another edge case of mismatched TLS models.
One library defines a symbol and _doesn't_ use it, so it has no
indication of whether the symbol is for static TLS or dynamic TLS,
and then two other libraries use it in different ways.
ld.elf_so: Test dynamic-then-static abuse via ctor.
ld.elf_so: Fix missing tab in debug/shl.mi in last change.
Fix interactions of initial-exec TLS model and dlopen
(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.
This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.
(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.
(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.
Avoid using uninitialized variable "symnum" when building with DEBUG
enabled by borrowing the rdbg_symname() macro from arch/x86_64.
ld.elf_so: Sprinkle more debug messages on dlopen and error.
PR pkg/57445
Fix MKDEBUGLIB build by adding these installed files to the debug

One could argue that these files are not of any use, so why install
them? I don't have a good argument either way, and this is (for
now) a simple work-around for PR bin/57455 Please feel free to
commit a different fix to avoid installing these files at all.
Fix markup of libh_ MKDEBUGLIB=yes only files
TLS variant I archs need to fudge the offset by the size of the TCB.
tests/libexec/ld.elf_so: Fix helper library makefiles.
1. Consolidate logic into a single helper.mk to reduce duplication.
2. Set NO* variables, not MK* variables which are reserved for user.
3. Avoid eager X!= in favour of lazy ${X:sh}.
4. Mark _g.a set list entries obsolete. Never should've been built!

The COMBREL logic predates thread-safety of the dynamic linker and
breaks the use of shared locks for the common symbol lookup case. It is
unlikely to provide any benefit for lazy binding or PLT lookups, so
provide equivalent functionality in the non-PLT relocation handling loop
by checking if the symbol used by the current relocation is the same as
the one used during the last lookup. No inter-object cachine is done as
it is also unlikely to be benefical.

it.
|

mycroft | Remove the `self' args to _rtld_relocate_objects() and
_rtld_relocate_nonplt_objects().

mycroft | Remove vestigal comments about _rtld_bind_start_0() -- it works now.
|
| 1.29 | 26-Sep-2002 |
mycroft | Make room for the argument save area in _rtld_start(). The PLT stub already
made room from _rtld_bind_start(), but add a comment explaining the instruction
it uses.

|

Also, fix more bugs in the large-PLT case -- my test program works now.
|
| 1.26 | 25-Sep-2002 |
mycroft | Swap registers %o0 and %o1 in the binder stub to say one instruction.
Fix an obvious bug in the 64-bit PLT fixup: the SLLX was by 12 bits, when it
should be 32.
Fix what *appear* to be two bugs in the >32768 PLT entry stub:
* One division was wrong (/14 rather than /24).
* We need to subtract 1048576 (to make the offset relative to the beginning of
the upper section), not add it.
This path is still untested, and buggy.
|

mycroft | Prototype different functions.
|
| 1.19 | 12-Sep-2002 |
mycroft | _rtld_bind_start() is not used in MI code, so declare it in the MD code.
|
| 1.18 | 11-Sep-2002 |
mycroft | Do self-relocation similar to sparc.
|
| 1.17 | 06-Sep-2002 |
mycroft | Expand the comment about the R_TYPE(RELATIVE) special-case, as it's not quite
obvious from the code. Also, just do it all the time, as an optimization.
|
| 1.16 | 06-Sep-2002 |
mycroft | Make the reloc tables const.
|
| 1.15 | 06-Sep-2002 |
mycroft | Pass down an additional flag to _rtld_relocate_nonplt_objects() which
indicates whether we're relocating ld.elf_so itself. Use this in some places
rather than hackish tests on `dodebug'. (The Alpha and HPPA `dodebug' tests
were actually noops, because RTLD_RELOCATE_SELF is not set, and therefore
dodebug is always true.)
|
| 1.14 | 06-Sep-2002 |
mycroft | Re-poison a lot of consts, now that the mark shite is gone.
|
| 1.13 | 06-Sep-2002 |
mycroft | Split _rtld_relocate_plt_object() into two MD functions:
* _rtld_relocate_plt_lazy() fixes up all the relocs pointing to the PLT. (On
most platforms it just does a simple base-relative fixup; on SPARC it does
nothing.)
* _rtld_relocate_plt_object() does immediate binding for a PLT entry.
The basic gist is that this saves a bit of time on SPARC (where the iteration
through the pltrela table was gratuitous), and a little less time on all other
platforms. A whole lot of #ifdef'ed crap is moved out of reloc.c, too.
NOT tested on: hppa sh x86_64
|
| 1.12 | 06-Sep-2002 |
mycroft | Repair a slight biff I made earlier -- do not exit the loop in
_rtld_relocate_nonplt_objects() early.
|
| 1.11 | 05-Sep-2002 |
mycroft | Partially fix up some debug printf()s that don't need to use defobj.
|
| 1.10 | 05-Sep-2002 |
mycroft | A few things:
* Pass a symbol number to _rtld_find_symdef(), not a r_info.
* Don't try to do a symbol lookup when we find an unsupported relocation;
instead get the symbol name from the referencing object's strtab.
* Add preliminary support for `-z combreloc'-style startup optimization on
i386, `#ifdef COMBRELOC'.
|
| 1.9 | 05-Sep-2002 |
mycroft | Rename _rtld_relocate_nonplt_object() to _rtld_relocate_nonplt_objects(),
and push the outer loop into it. This actually shaves a couple % off startup
time at least on PCs.
|
| 1.8 | 05-Sep-2002 |
mycroft | Split _rtld_relocate_nonplt_object() into separate MD files.
|

Replace COMBREL with just-in-time check in _rtld_relocate_nonplt_objects.
The COMBREL logic predates thread-safety of the dynamic linker and
breaks the use of shared locks for the common symbol lookup case. It is
unlikely to provide any benefit for lazy binding or PLT lookups, so
provide equivalent functionality in the non-PLT relocation handling loop
by checking if the symbol used by the current relocation is the same as
the one used during the last lookup. No inter-object cachine is done as
it is also unlikely to be benefical.
Testing with Firefox startup on AMD64 shows a small performance gain by
the new method.
Drop symbol number from default branch diagnostic, it isn't set at this
point and most likely not valid either.
Expand symnum, GCC's uninitialized used tracking is too imprecise.
Fix C&P bug. Deal with more MIPS hacks overriding def.
Add last_symnum, move up def and defobj.
Add back symnum, fix debug print.
Replace last use of r_type.
Fix indentation.
Fix indentation.

ld.elf_so: New test for extern initial-exec TLS, PR toolchain/50277.
ld.elf_so: Fix extern TLS test to match PR toolchain/50277.
Now it's actually testing the problem.
ld.elf_so: Nix inadvertently committed private test program.
ld.elf_so: Fix set lists for MKDEBUG=yes builds with t_tls_extern.
ld.elf_so: Sprinkle tls debug messages.
ld.elf_so: Make tls alloc debug messages more detailed and greppable.
ld.elf_so: Test variations on PR toolchain/50277.
ld.elf_so: Test extern dynamic TLS too.
ld.elf_so: Factor out logic in TLS tests to make writing more easier.
No functional change intended.
ld.elf_so: Test TLS abuse of static def, dynamic use and vice versa.
ld.elf_so: Shorter test names.
No functional non-cosmetic change intended.
ld.elf_so: Separately test eager and lazy resolution of def tls ptr.
eager: before loading use library
lazy: after loading use library
Add recent ld.elf_so test helpers debug info
ld.elf_so: Add new files to debug/shl.mi.
ld.elf_so: tls_extern dynamic_defabuse_eager must xfail differently.
If a symbol has already been resolved as dynamic TLS, any library
that tries to use it as static TLS cannot be dlopened.
ld.elf_so: Test another edge case of mismatched TLS models.
One library defines a symbol and _doesn't_ use it, so it has no
indication of whether the symbol is for static TLS or dynamic TLS,
and then two other libraries use it in different ways.
ld.elf_so: Test dynamic-then-static abuse via ctor.
ld.elf_so: Fix missing tab in debug/shl.mi in last change.
Fix interactions of initial-exec TLS model and dlopen
(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.
This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.
(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.
(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.
Avoid using uninitialized variable "symnum" when building with DEBUG
enabled by borrowing the rdbg_symname() macro from arch/x86_64.
ld.elf_so: Sprinkle more debug messages on dlopen and error.
PR pkg/57445
Fix MKDEBUGLIB build by adding these installed files to the debug
set list.
XXX
One could argue that these files are not of any use, so why install
them? I don't have a good argument either way, and this is (for
now) a simple work-around for PR bin/57455 Please feel free to
commit a different fix to avoid installing these files at all.
Fix markup of libh_ MKDEBUGLIB=yes only files
TLS variant I archs need to fudge the offset by the size of the TCB.
tests/libexec/ld.elf_so: Fix helper library makefiles.
1. Consolidate logic into a single helper.mk to reduce duplication.
2. Set NO* variables, not MK* variables which are reserved for user.
3. Avoid eager X!= in favour of lazy ${X:sh}.
4. Mark _g.a set list entries obsolete. Never should've been built!

joerg | Replace COMBREL with just-in-time check in _rtld_relocate_nonplt_objects.
The COMBREL logic predates thread-safety of the dynamic linker and
breaks the use of shared locks for the common symbol lookup case. It is
unlikely to provide any benefit for lazy binding or PLT lookups, so
provide equivalent functionality in the non-PLT relocation handling loop
by checking if the symbol used by the current relocation is the same as
the one used during the last lookup. No inter-object cachine is done as
it is also unlikely to be benefical.
Testing with Firefox startup on AMD64 shows a small performance gain by
the new method.

indicates whether we're relocating ld.elf_so itself. Use this in some places
rather than hackish tests on `dodebug'. (The Alpha and HPPA `dodebug' tests
were actually noops, because RTLD_RELOCATE_SELF is not set, and therefore
dodebug is always true.)
|
| 1.8 | 06-Sep-2002 |
mycroft | Introduce a new flag, `isdynamic', which is used to remember whether the
executable was of type ET_DYN. Use this instead of `mainprog' to determine
whether we need to do base-relative fixups of the PLT. (This allows loading
non-relocatable objects, should we desire to do that at some point...)

mycroft | Re-poison a lot of consts, now that the mark shite is gone.

mycroft | Split _rtld_relocate_plt_object() into two MD functions:
* _rtld_relocate_plt_lazy() fixes up all the relocs pointing to the PLT. (On
most platforms it just does a simple base-relative fixup; on SPARC it does
nothing.)
* _rtld_relocate_plt_object() does immediate binding for a PLT entry.
The basic gist is that this saves a bit of time on SPARC (where the iteration
through the pltrela table was gratuitous), and a little less time on all other
platforms. A whole lot of #ifdef'ed crap is moved out of reloc.c, too.

* Don't try to do a symbol lookup when we find an unsupported relocation;
instead get the symbol name from the referencing object's strtab.
* Add preliminary support for `-z combreloc'-style startup optimization on
i386, `#ifdef COMBRELOC'.

- Consistently record the delta to the end of the relocation group for

Hidden ifunc is now supported on all ifunc platforms, even when using
-fno-plt. The combination of -fno-plt and relro is broken due to
incorrect GNU ld output though.

Fix interactions of initial-exec TLS model and dlopen
(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.
This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.
(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.
(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.

Rework ifunc support to address a number of short comings:

- Consistently record the delta to the end of the relocation group for
non-PLT IRELATIVE relocations

The COMBREL logic predates thread-safety of the dynamic linker and

unlikely to provide any benefit for lazy binding or PLT lookups, so
provide equivalent functionality in the non-PLT relocation handling loop
by checking if the symbol used by the current relocation is the same as
the one used during the last lookup. No inter-object cachine is done as
it is also unlikely to be benefical.
Testing with Firefox startup on AMD64 shows a small performance gain by
the new method.

Initialize _rtld_sym_zero.st_value to -_rtld_objself.maprelocbase. Now when

mycroft | Split _rtld_relocate_plt_object() into two MD functions:
* _rtld_relocate_plt_lazy() fixes up all the relocs pointing to the PLT. (On
most platforms it just does a simple base-relative fixup; on SPARC it does
nothing.)
* _rtld_relocate_plt_object() does immediate binding for a PLT entry.
The basic gist is that this saves a bit of time on SPARC (where the iteration
through the pltrela table was gratuitous), and a little less time on all other
platforms. A whole lot of #ifdef'ed crap is moved out of reloc.c, too.

* Add preliminary support for `-z combreloc'-style startup optimization on
i386, `#ifdef COMBRELOC'.

ld.elf_so: New test for extern initial-exec TLS, PR toolchain/50277.
ld.elf_so: Fix extern TLS test to match PR toolchain/50277.
Now it's actually testing the problem.
ld.elf_so: Nix inadvertently committed private test program.
ld.elf_so: Fix set lists for MKDEBUG=yes builds with t_tls_extern.
ld.elf_so: Sprinkle tls debug messages.
ld.elf_so: Make tls alloc debug messages more detailed and greppable.
ld.elf_so: Test variations on PR toolchain/50277.
ld.elf_so: Test extern dynamic TLS too.
ld.elf_so: Factor out logic in TLS tests to make writing more easier.
No functional change intended.
ld.elf_so: Test TLS abuse of static def, dynamic use and vice versa.
ld.elf_so: Shorter test names.
No functional non-cosmetic change intended.
ld.elf_so: Separately test eager and lazy resolution of def tls ptr.
eager: before loading use library
lazy: after loading use library
Add recent ld.elf_so test helpers debug info
ld.elf_so: Add new files to debug/shl.mi.
ld.elf_so: tls_extern dynamic_defabuse_eager must xfail differently.
If a symbol has already been resolved as dynamic TLS, any library
that tries to use it as static TLS cannot be dlopened.
ld.elf_so: Test another edge case of mismatched TLS models.
One library defines a symbol and _doesn't_ use it, so it has no
indication of whether the symbol is for static TLS or dynamic TLS,
and then two other libraries use it in different ways.
ld.elf_so: Test dynamic-then-static abuse via ctor.
ld.elf_so: Fix missing tab in debug/shl.mi in last change.
Fix interactions of initial-exec TLS model and dlopen
(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.
This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.
(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.
(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.
Avoid using uninitialized variable "symnum" when building with DEBUG
enabled by borrowing the rdbg_symname() macro from arch/x86_64.
ld.elf_so: Sprinkle more debug messages on dlopen and error.
PR pkg/57445
Fix MKDEBUGLIB build by adding these installed files to the debug
set list.
XXX
One could argue that these files are not of any use, so why install
them? I don't have a good argument either way, and this is (for
now) a simple work-around for PR bin/57455 Please feel free to
commit a different fix to avoid installing these files at all.
Fix markup of libh_ MKDEBUGLIB=yes only files
TLS variant I archs need to fudge the offset by the size of the TCB.
tests/libexec/ld.elf_so: Fix helper library makefiles.
1. Consolidate logic into a single helper.mk to reduce duplication.
2. Set NO* variables, not MK* variables which are reserved for user.
3. Avoid eager X!= in favour of lazy ${X:sh}.
4. Mark _g.a set list entries obsolete. Never should've been built!
