 1.151  02-May-2025  riastradh ld.elf_so(1): Skip the ctype(3) guard pages.

These came in via libc_pic.a. They aren't very useful because
nothing mprotects them in ld.elf_so -- ld.elf_so ignores its own
constructors. We could fill them with gibberish in a feeble attempt
to highlight ctype(3) abuse...or we could just audit ld.elf_so and
save on the memory by.

This uses a .PATH.c reachover for the ctype_.c file rather than
pulling ctype_.pico out of libc_pic.a.

Sampling of space savings:

79680 1048 1860 82588 1429c ld.elf_so.after/ld.elf_so

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

Don't need it outside immediate _rtld_donelist_init callers.

 1.148  07-Oct-2023  rin Drop -O[01] hacks for vax; no longer necessary for patched GCC 10

PR port-vax/57646: Import major vax toolchain fix by Kalvis Duckmanton

XXXRO: GCC 12 may require hacks for a while, but it turned out that
GCC 12 should be treated differently from older versions; a lot of new
files need -O[01] flags, while some may no longer require it.

I will take a look later.

Note that these hacks are not required if Kalvis's patches for GCC 12
are applied.

Keep doc/HACKS entries for a while (will be sync with update for GCC 12).

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

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

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

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

 1.103  09-Mar-2011  joerg Add TLS support infrastructure. For dynamic binaries, ld.elf_so exports
_rtld_tls_allocate and _rtld_tls_free. libpthread uses this functions to
setup the thread private area of all new threads. ld.elf_so is
responsible for setting up the private area for the initial thread.
Similar functions are called from _libc_init for static binaries, using
dl_iterate_phdr to access the ELF Program Header.

Add test cases to exercise the different TLS storage models. Test cases
are compiled and installed on all platforms, but are skipped on
platforms not marked for TLS support.

This material is based upon work partially supported by
The NetBSD Foundation under a contract with Joerg Sonnenberger.

It is inspired by the TLS support in FreeBSD by Doug Rabson and the
clean ups of the DragonFly port of the original FreeBSD modifications.

 1.97  06-Jul-2010  mrg remove almost all the ability to build netbsd with an a.out target.
we're ELF now, and there are many missing checks against OBJECT_FMT.
if we ever consider switching, the we can figure out what new ones
we need but for now it's just clutter.

this doesn't remove any of the support for exec_aout or any actually
required-for-boot a.out support, only the ability to build a netbsd
release in a.out format. ie, most of this code has been dead for
over a decade.

i've tested builds on vax, amd64, i386, mac68k, macppc, sparc, atari,
amiga, shark, cats, dreamcast, landisk, mmeye and x68k. this covers
the 5 MACHINE_ARCH's affected, and all the other arch code touched.
it also includes some actual run-time testing of sparc, i386 and
shark, and i performed binary comparison upon amiga and x68k as well.


some minor details relevant:
- move shlib.[ch] from ld.aout_so into ldconfig proper, and cut them
down to only the parts ldconfig needs
- remove various unused source files
- switch amiga bootblocks to using elf2bb.h instead of aout2bb.h

 1.65  21-Feb-2004  skrll Move common LDFLAGS into Makefile from arch/*/Makefile.inc
 1.64  21-Oct-2003  lukem Rework how MAKEVERBOSE operates:

* Don't bother prefixing commands with a line of ${_MKCMD}\
and instead rely upon "make -s". This is less intrusive on
all the Makefiles than the former. Idea from David Laight.

* Rename the variables use to print messages. The scheme now is:
_MKMSG_FOO Run _MKMSG 'foo'
_MKTARGET_FOO Run _MKMSG_FOO ${.TARGET}
From discussion with Alistair Crooks.
 1.63  19-Oct-2003  lukem rework to use the newer _MKMSGCREATE (et al) macros

run with a fully dynamic userland (modulo a few remaining
gremlins affecting a couple of binaries).
 1.60  26-Feb-2003  uwe Do not add ${LIBC_PIC} to DPADD if MKPICINSTALL is "no".
 1.59  05-Oct-2002  junyoung Disable DEBUG again.
 1.58  05-Oct-2002  junyoung Don't call _rtld_process_mapping() with null string.
 1.57  27-Sep-2002  thorpej Only use the MKDYNAMICROOT semantics (i.e. -rpath=/lib,/usr/lib and
-dynamic-linker=/libexec/ld.elf_so) if the BINDIR of the program being
built is /bin or /sbin.

The reason we do this is because now all programs *except* those in
/bin and /sbin (i.e. the "special cases") match the default the compiler
uses, which is what is used for things in e.g. xsrc, pkgsrc, and other
random 3rd party programs.

This is done by decoupling where a shlib is installed from how it
is located. Two new variables, SHLIBINSTALLDIR and SHLINKINSTALLDIR,
contain the former information, and key off MKDYNAMICROOT only. SHLIBDIR
and SHLINKDIR contain the latter, and key off MKDYNAMICROOT and BINDIR.

The SHLIBINSTALLDIR, SHLIBDIR, _LIBSODIR, SHLINKINSTALLDIR, and
SHLINKDIR parameters are moved to a new <bsd.shlib.mk>; see bsd.README
for usage details.
 1.56  26-Sep-2002  mycroft *poof*
-fomit-frame-pointer works on 68k.
 1.55  26-Sep-2002  mycroft -vomit-frame-pointer is buggy on 68k. *sigh*
 1.54  26-Sep-2002  mycroft By default, compile without DEBUG, and with -fomit-frame-pointer.
 1.53  13-Sep-2002  mycroft Turn DEBUG back on by default. It doesn't take much space.
 1.52  31-Aug-2002  mycroft Turn off DEBUG by default, and compile with -O3. (Tested on Alpha, ARM,
x86 and PowerPC.)
 1.51  19-Aug-2002  lukem Use ${NETBSDSRCDIR}/some/path instead of ${.CURDIR}/../../some/path
 1.50  10-Aug-2002  thorpej Build for "armeb".
 1.49  10-Jul-2002  fredette Add support for dynamic linking on HP PA-RISC.
 1.48  01-Mar-2002  tv branches: 1.48.2;
Don't bomb if the ${DPADD} files are missing -- we want at least one of
them, where the other may not exist, and the linker will fail for us if
both don't exist.
 1.47  04-Feb-2002  thorpej Use ${MACHINE_CPU} to assign ARCHSUBDIR.
 1.46  03-Feb-2002  thorpej Add support for dynamic linking on the SuperH. From Marcus Comstedt,
with some bug fixes (namely, don't forget to consider the addend when
processing relocations) from me.
 1.45  23-Jan-2002  skrll Install the man page on a.out systems as well so that the man set is the
same for all.
 1.44  04-Jan-2002  tv Revert rev. 1.30 (partly). If MKPICINSTALL=no in mk.conf, libc_pic.a will
NOT be installed by the time we build here.

However, allow the link to look in both src/lib/libc and $DESTDIR/usr/lib.
 1.43  28-Dec-2001  lukem - Allow RTLD_DEFAULT_LIBRARY_PATH to be overridden.
- If ${SHLIBDIR} != ${LIBDIR}, then set RTLD_DEFAULT_LIBRARY_PATH to
${SHLIBDIR}:${LIBDIR}
 1.42  28-Dec-2001  lukem if SHLINKDIR != /usr/libexec, install compat symlink
 1.41  28-Dec-2001  lukem * Add user-controlled mk.conf variables
- SHLIBDIR Location to install shared libraries if ${USE_SHLIBDIR}
is "yes". Defaults to "/usr/lib".

- USE_SHLIBDIR If "yes", install shared libraries in ${SHLIBDIR}
instead of ${LIBDIR}. Defaults to "no".
Sets ${_LIBSODIR} to the appropriate value.
This may be set by individual Makefiles as well.

- SHLINKDIR Location of shared linker. Defaults to "/usr/libexec".
If != "/usr/libexec", change the dynamic-linker
encoded in shared programs

* Set USE_SHLIBDIR for libraries used by /bin and /sbin:
libc libcrypt libcrypto libedit libipsec libkvm libm libmi387
libtermcap libutil libz

* If ${_LIBSODIR} != ${LIBDIR}, add symlinks from ${LIBDIR}/${LIB}.so*
to ${_LIBSODIR}/${LIB}.so* for compatibility.

* Always install /sbin/init statically (for now)


The net effect of these changes depends on how the variables are set:

1.) If nothing is set or changed, there is no change from the
current behaviour:
- Static /bin, /sbin, and bits of /usr/*
- Dynamic rest
- Shared linker is /usr/libexec/ld*so

2.) If the following make variables are set:
LDSTATIC=
SHLINKDIR=/lib
SHLIBDIR=/lib
Then the behaviour becomes:
- Dynamic tools
- .so libraries used by /bin and /sbin are installed to /lib,
with symlinks from /usr/lib/lib*so to -> /lib/lib*so
where appropriate
- Shared linker is /lib/ld*so

3.) As per 2.), but add the following variable:
USE_SHLIBDIR=yes
This forces all .so's to be instaleld in /lib (with compat
symlinks), not just those tagged by their Makefiles to be.
Again, compat symlinks are installed
 1.40  14-Dec-2001  thorpej Don't put compiler options into CPPFLAGS.
 1.39  31-Oct-2001  skrll Add a man page for ld.elf_so.

 1.36  14-Jan-2001  christos back out previous commit; I found a better way of handling the missing
dependencies.
 1.35  14-Jan-2001  christos Don't use ${OBJS} in the dependency line, cause it is not defined yet.
Also add a .NOTMAIN for good measure.
 1.34  10-Nov-2000  mycroft When dlopen()ing with RTLD_GLOBAL, also make dependent libraries RTLD_GLOBAL.
 1.33  14-Jul-2000  matt Split DEBUG into two lines to make it easier to enable each separately.
 1.32  03-Jul-2000  matt If OBJECT_FMT is ELF and MACHINE_ARCH = vax, build ld.elf_so
 1.31  26-Mar-2000  mycroft Don't try to get libc_pic from the libc compile directory. If we're doing a
build, libc has already been installed.
 1.30  05-Jul-1999  thorpej Protect certain definitions from view by crt0, by wrapping them in
#ifdef _RTLD_SOURCE.

Should fix the "variable page size" build error of crt0 on the SPARC.
 1.29  07-May-1999  thorpej Don't even make depend if we're not going to build ld.elf_so. this is
especially important if the assembler syntax is different.
 1.28  29-Apr-1999  kleink Always use ${MACHINE_ARCH} rather than ${MACHINE}, and reorder architectures
a bit.
 1.27  29-Apr-1999  kleink Add m68k code.
 1.26  19-Mar-1999  thorpej Move the link.h files for the different shlib formats via repository copy,
and rename them to match the executable format. Introduce a new link.h
file which automatically picks the correct header based on the target of
the toolchain.

 1.24  03-Mar-1999  christos Make this compile without -DRTLD_LOADER and fix printf format problems on
the alpha.
 1.23  03-Mar-1999  jonathan Makefile ${MACHINE_ARCH} changes for mips{eb,el}, as suggested by
Izumi Tsutsui <tsutsui@ceres.dti.ne.jp>
 1.22  24-Feb-1999  christos Cleanup global variable access so rtld can be self relocating. Also KNF
reloc.c and move md sparc parts to arch/sparc/mdreloc.c
Now we don't need to load at address 0 on the i386 and the mips should be
trivial to fix.
 1.21  21-Feb-1999  kleink Replace home-grown header file installation with INCS/INCSDIR; from Erik
Bertelsen in PR bin/6869.
 1.20  13-Feb-1999  lukem convert from NOxxx= to MKxxx=no.

 1.18  10-Jan-1999  christos Add i386 bits
 1.17  24-Nov-1998  tsubai Add powerpc support.
 1.16  13-Sep-1998  mrg remove MD asm as(1) comments from sysident.h, placing them in a comment
above the asm() block. now we can share sysident.h across all ports..
change ld.elf_so to be for $MACHINE == sparc64 not sparc (yet!).
 1.15  27-Aug-1998  tv Use -L for libc's objdir in case NOPICINSTALL is set in mk.conf.
 1.14  13-Aug-1998  christos Don't install the ELF link.h in a.out systems!@#$#@
 1.13  04-Aug-1998  tv Use NOPIC to mean "no shared libraries", not NOSHLIB.
 1.12  25-Mar-1998  mhitch Add support for mips.
 1.11  23-Feb-1998  jonathan More table-driven changes for different toolchains:
* new bsd.own.mk variable OBJECT_FMT with values "a.out" or "ELF".
* use OBJECT_FMT in Makefile tests that depend on toolchain.
* Add new bsd.own.mk variable NOSHLIB that, if set indicates a given
port doesnt yet do shared libraries. Set on powerpc.
* Document new feature-test variables in src/share/mk/bsd.README.
Tested on i386, mips, fakedup Alpha environment.
 1.10  25-Oct-1997  cjs Link with the stuff we compiled, rather that whatever random stuff happens
to be installed on the system we're compiling on.
 1.9  23-Oct-1997  jonathan Install our ELF-aware link.h into /usr/include on mips hosts.
 1.8  22-Oct-1997  lukem use CPPFLAGS instead of CFLAGS
 1.7  23-Jun-1997  mrg branches: 1.7.2;

 1.6  31-May-1997  cjs Back out BUILDDIR and NOINSTALL changes.
 1.5  26-May-1997  cjs branches: 1.5.2;
These updates to the build allow building against include files
and libs in the object tree, if you use a separate object tree,
while maintaining backward compatability with other build methods.
See the notes in src/share/mk/bsd.README for full details. Note
that the `make includes' target now only installs the include files
in the build directory (if you use one--otherwise they go in DESTDIR
just like before); `make install' will install include files in
DESTDIR.
 1.4  17-Apr-1997  thorpej STRIP -> STRIPFLAG (sign, I guess I forgot to check this one in last night)
 1.3  10-Apr-1997  cgd pull in arch-specific Makefile.inc only if it exists
 1.2  24-Mar-1997  christos - Makefile cleanups
 1.1  16-Dec-1996  cgd First cut at an ELF shared loader. Originally from John Polstra's FreeBSD elf
kit, then hacked on by Matt Thomas <matt@3am-software.com>, then by me (to
make it work with new versions of the toolchain, etc.). This runs, but it's
in serious need of cleaning and/or a fair bit of reworking. See the README
file for more information, and a list of things to do.

PR/39240: Satoshi Suetake: Don't fail when attempting to resolve weak symbols
when we are doing immediate binding, leave them alone and they will be dealt
with later during lazy binding. From skrll@
Implement negative cache checks for symbol lookups.
Uses the Donelist idea from FreeBSD.
Use alloca(3) instead of local xmalloc for creating our DoneLists.
This allows threaded programs to use us a little better, PR lib/43005.
Implement dl_iterate_phdr.
Somewhat taken from FreeBSD. Manual page from OpenBSD.
 1.87.2.1  06-Jan-2011  riz Apply patch (requested by mrg in ticket #1499):

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

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

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

PR 54093: Align static TLS area to max_align_t.
Use alignof and not size_t for platforms with non-natural base
alignments.

Mirror the ld.elf_so logic for handling aligning the TLS size.
Most noticable, recompute the start of the TLS area for variant I
relative to the TCB. This makes a difference when the segment size and
base alignment don't agree.

Fix PR/54074 and PR/54093 completely.
More similar to the ld.elf_so logic, it is necessary to align with
p_align first. Also, invert the #ifdef condition for consistency.

Should fix regression for static linking binaries:
