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.

Various fixes / changes from Ryo Shimizu / Toru Nishimura to make this
work.
_rtld_call_ifunc copied from other rela platforms by me - not tested in
any way.
|
| 1.6 | 28-Aug-2017 |
nisimura | explain AARCH64 PLT design
|
| 1.5 | 23-Aug-2017 |
nisimura | - avoid caddr_t. use Elf_Addr instead.
- iron out rdbg() errors.
|
| 1.4 | 10-Aug-2017 |
joerg | Add IRELATIVE support for ARM, X86 and PowerPC.
|
| 1.3 | 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.
|
| 1.2 | 25-Aug-2014 |
joerg | branches: 1.2.8;
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
Inspired by FreeBSD's r228435 by kib@freebsd.org.

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: 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.

(1) If an initial-exec relocation was used for a non-local symbol

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

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

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.

| 1.18 | 13-Sep-2002 |
mycroft | Do not use the implicit addend on REFQUAD relocs (same as GLOB_DAT).
|
| 1.17 | 12-Sep-2002 |
mycroft | Nuke -DRTLD_RELOCATE_SELF and `dodebug' from orbit.
|
| 1.16 | 12-Sep-2002 |
mycroft | _rtld_bind_start() is not used in MI code, so declare it in the MD code.
|
| 1.15 | 11-Sep-2002 |
mycroft | Implement _rtld_relocate_nonplt_self() on Alpha.
|
| 1.14 | 08-Sep-2002 |
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...)
|
| 1.11 | 06-Sep-2002 |
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
|
| 1.9 | 05-Sep-2002 |
mycroft | Partially fix up some debug printf()s that don't need to use defobj.
|
| 1.8 | 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'.
|
| 1.7 | 05-Sep-2002 |
mycroft | Fix one indentation error.
|
| 1.6 | 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.
|
| 1.5 | 05-Sep-2002 |
mycroft | Split _rtld_relocate_nonplt_object() into separate MD files.
|
| 1.4 | 05-Sep-2002 |
mycroft | Make _rtld_setup_pltgot() a consistent interface on all platforms.
|
| 1.3 | 04-Sep-2002 |
mycroft | There is no need to do an imb after each call to the binder, because we only
patch the GOT, not the PLT. However, do an imb when setting up the PLT thunk,
just in case.
|
| 1.2 | 14-Dec-2001 |
thorpej | branches: 1.2.2;
Add code to peek into the PLT and determine which PLT entry format
is being used.
|
| 1.1 | 13-Dec-2001 |
thorpej | Supply two lazy binding routines for Alpha: one that works with the
old PLT format, and one that works with the new.
XXX We currently always use _rtld_bind_start_old() in
_rtld_setup_alpha_pltgot(). We need to add code to peek
into one of the PLT entries to see which format it's in
and pick the correct binding routine.

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.

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: 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!

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.
|
| 1.9 | 04-Sep-2002 |

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

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:
- 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.

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.

function descriptors on the stack, if the address is not leaked outside.

Refactor common code to _rtld_relocate_plt_object to i386 and arm so they
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.

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...)

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 | Partially fix up some debug printf()s that don't need to use defobj.

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.

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.

joerg | branches: 1.50.2;
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

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

Refactor common code to _rtld_relocate_plt_object to i386 and arm so they

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.

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.)
|
| 1.10 | 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.
|
| 1.8 | 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'.

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.

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.

supposed to be the case for -Bsymbolic anyway.

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.

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.

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

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.
NOT tested on: hppa sh x86_64

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'.

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.

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

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: 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: 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: 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 | 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.

(all via patch)
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!

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

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

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.
Testing with Firefox startup on AMD64 shows a small performance gain by
the new method.

skrll | Correct the in_plt parameter of a couple of _rtld_find_symdef calls.
The mips_reloc.c case is a no-op as _rtld_symlook_obj ignores in_plt for
MIPS.
OK'ed by Charles.
|
| 1.37 | 05-Oct-2002 |
mycroft | Minor cleanup.
|
| 1.36 | 26-Sep-2002 |
mycroft | Add an iffy heuristic that allows us to do lazy binding with new objects, but
detect old objects and deal with them.
|
| 1.35 | 25-Sep-2002 |
mycroft | Minor cleanup, for clarity.
|
| 1.34 | 25-Sep-2002 |
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.

thorpej | It is possible for reloc entries to point to unaligned locations; handle
this.
|
| 1.32 | 13-Sep-2002 |
mycroft | In _rtld_bind_mips(), if the symbol is undefined, die.
|
| 1.31 | 13-Sep-2002 |
mycroft | Add an explanatory comment.
|
| 1.30 | 13-Sep-2002 |
mycroft | The sense of the SHN_ABS test has always been reversed. Fortunately nobody
ever tried to reference stuff like _DYNAMIC_LINK and _gp_disp in C code...
|
| 1.29 | 13-Sep-2002 |
mycroft | Put back the lazy binding. For some bizarre reason, the linker occasionally
does not create a PLT entry for a symbol, so we test st_value!=0 to see
whether we can do a PLT fixup.
|
| 1.28 | 13-Sep-2002 |
mycroft | Er, turn off lazy binding for the moment. It doesn't seem to be fully working.
|
| 1.27 | 13-Sep-2002 |
mycroft | Simplify the GOT relocation code somewhat.
|
| 1.26 | 13-Sep-2002 |
mycroft | Actually do lazy binding on this platform.
|
| 1.25 | 13-Sep-2002 |
mycroft | Remove an old comment.
|
| 1.24 | 13-Sep-2002 |
mycroft | _rtld_bind() is not used on MIPS. Should probably move it to MD code.
|
| 1.23 | 12-Sep-2002 |
mycroft | Nuke -DRTLD_RELOCATE_SELF and `dodebug' from orbit.
|
| 1.22 | 12-Sep-2002 |
mycroft | _rtld_bind_start() is not used in MI code, so declare it in the MD code.
|
| 1.21 | 12-Sep-2002 |
mycroft | Slight tweak.
|
| 1.20 | 12-Sep-2002 |
mycroft | The GOT is Elf_Addr[], not Elf_Word[]...
|
| 1.19 | 12-Sep-2002 |
mycroft | Clean up a little.
|
| 1.18 | 12-Sep-2002 |
mycroft | Move GOT relocation code from _rtld_setup_pltgot() to
_rtld_relocate_nonplt_objects(). Add GOT self-relocation in
_rtld_relocate_nonplt_self().
MIPS ld.elf_so can now relocate itself.
|
| 1.17 | 12-Sep-2002 |
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...)
|
| 1.14 | 06-Sep-2002 |
mycroft | More const poisoning. Now the entire _rtld_bind() path useds a const Obj_Entry.
|
| 1.13 | 06-Sep-2002 |
mycroft | Re-poison a lot of consts, now that the mark shite is gone.
|
| 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.
NOT tested on: hppa sh x86_64
|
| 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 MIPS relocation goo into mips_reloc.c.
|
| 1.7 | 05-Sep-2002 |
junyoung | Remove unused arguments of _rtld_find_symdef().
|
| 1.6 | 05-Sep-2002 |
mycroft | Make _rtld_setup_pltgot() a consistent interface on all platforms.
|
| 1.5 | 24-Nov-2001 |
rafal | branches: 1.5.2;
Fix bug found by Izumi Tsutsui -- if _rtld_find_symdef returned NULL, the
runtime linker would crash. Restore behavior similar to version 1.3, where
the runtime linker continues on, ignoring the symbol.
|
| 1.4 | 14-Oct-2001 |
rafal | Fix how underfined weak symbols are treated -- before, ld.so would do nothing
with them, rather than defaulting them to zero. This caused breakage with
the drawf EH stuff and init/fini code when they weren't used by the caller
(and hence the appropriate handlers were left undefined). Also fix an un-
initialized variable in symbol.c that only MIPS MD code tripped over.
|
| 1.3 | 07-Nov-1999 |
mycroft | branches: 1.3.4;
Make this more likely to compile with ld.elf_so changes. (But this is

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.

1. Consolidate logic into a single helper.mk to reduce duplication.
2. Set NO* variables, not MK* variables which are reserved for user.

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.

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!

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 | branches: 1.63.2;
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.

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.

eager: before 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.

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!

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: New test for extern initial-exec TLS, 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: 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.

Fix MKDEBUGLIB build by adding these installed files to the debug

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

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.
Testing with Firefox startup on AMD64 shows a small performance gain by
the new method.

joerg | Add TLS support for AMD64, i386 and SH3.
This material is based upon work partially supported by
The NetBSD Foundation under a contract with Joerg Sonnenberger.
|
| 1.28 | 06-Aug-2010 |
joerg | Reduce header pollution for mdreloc.c. Make Obj_Entry argument of
_rtld_relocate_nonplt_objects non-const in preparation for TLS support.

jmmv | Remove trailing \n in calls to _rtld_error: a newline is automatically
added by a call to the function.
|
| 1.25 | 16-Mar-2009 |
lukem | Fix const issues (cast const pointers to "const uint8_t *" instead of "caddr_t")

matt | Refactor common code to _rtld_relocate_plt_object to i386 and arm so they
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.
|
| 1.22 | 21-May-2006 |
mrg | branches: 1.22.20;
avoid more GCC4 uninitialised variable problems. (sh3 known, vax guessed.)

skrll | Add __RCSID.
|

|
| 1.18 | 05-Jul-2003 |
marcus | Removed unused function.
|
| 1.17 | 05-Jul-2003 |
tsutsui | Add function prototype declarations.
|
| 1.16 | 02-Jul-2003 |
marcus | Bugfix: Don't pick addend both from reloc and contents at the same time.
|
| 1.15 | 30-Jun-2003 |
marcus | Updated to work with current rtld code.
|
| 1.14 | 03-Oct-2002 |
mycroft | Skip the lazy PLT relocation if relocbase==0 (useful if libraries are loaded
at their VMA address).
|
| 1.13 | 26-Sep-2002 |
mycroft | Remove the `self' args to _rtld_relocate_objects() and
_rtld_relocate_nonplt_objects().
|
| 1.12 | 12-Sep-2002 |
mycroft | Nuke -DRTLD_RELOCATE_SELF and `dodebug' from orbit.
|
| 1.11 | 12-Sep-2002 |
mycroft | _rtld_bind_start() is not used in MI code, so declare it in the MD code.
|
| 1.10 | 11-Sep-2002 |
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
|
| 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 |
mycroft | Make _rtld_setup_pltgot() a consistent interface on all platforms.
|
| 1.19.4.2 | 28-May-2004 |
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
|
| 1.19.4.1 | 24-Jul-2003 |

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.

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: Test another edge case of mismatched TLS models.

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.

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.

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.

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.
|
| 1.54 | 29-Mar-2018 |
joerg | Move the complex logic for dynamically writing branches from ld.elf_so
into a header for reuse in crt0.o for static ifunc support. Change the
existing logic for sparc64 to use the Bicc variant of ba,a as it allows
+-8MB displacement compared to the BPcc variant's +-1MB. Teach the sparc
variant the same trick for using ba,a and not sethi+jmp when possible.

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.

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 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.

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.

Remove a debug assert that does not hold for PIE (e.g. phdr = 0x40, but
obj has not been mapped at 0, so obj->phdr is 0x100040).

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: 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: 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 | 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 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.

skrll | ANSIfy and de-__P().
|

fvdl | Replace return -1 in rtld_bind with _rtld_die() call.
|

fvdl | Implement self-relocation as is required now.
|

mycroft | Skip the lazy PLT relocation if relocbase==0 (useful if libraries are loaded
at their VMA address).
|
| 1.19 | 26-Sep-2002 |
mycroft | Remove the `self' args to _rtld_relocate_objects() and
_rtld_relocate_nonplt_objects().

mycroft | Partly fix this port -- still needs a self-reloc function.

mycroft | Nuke -DRTLD_RELOCATE_SELF and `dodebug' from orbit.
|
| 1.16 | 12-Sep-2002 |
mycroft | _rtld_bind_start() is not used in MI code, so declare it in the MD code.
|
| 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 | 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...)
|
| 1.13 | 06-Sep-2002 |
mycroft | Re-poison a lot of consts, now that the mark shite is gone.
|
| 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.
NOT tested on: hppa sh x86_64
|
| 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.
|
| 1.7 | 05-Sep-2002 |

|
| 1.6 | 05-Sep-2002 |

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.

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: 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!

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
