2005-03-14Oops, fix typo.Joakim Tjernlund
2005-03-14Make mips at least compileEric Andersen
2005-03-14Fix up x86 so it compiles again.Eric Andersen
2005-03-14Simplify PT_INTERP handling.Joakim Tjernlund
Add prototype for _dl_boot()
2005-03-14Generalize optimized relative reloc procesing.Joakim Tjernlund
Add elf_machine_dynamic() and elf_machine_load_address() for all archs. elf_machine_dynamic() replaces the #ifdef mess to get at the GOT. elf_machine_load_address() is needed to execute ldso directly, this is not complete yet. I probably broke one or two archs(only tested PPC) so please try and report problems. For a report to be useful you need to enable __SUPPORT_LD_DEBUG_EARLY__ and __SUPPORT_LD_DEBUG__
2005-03-14Force suid apps to do unlazy binding of the PLT relocs.Joakim Tjernlund
See http://bugs.gentoo.org/show_bug.cgi?id=71609 for more details. Reported by Peter Mazinger.
2005-03-10Use DT_RELCONT_IDX to optimize the relocation of R_PPC_RELATIVEJoakim Tjernlund
relocs. All RELA arches can probably copy this. REL archs will have to delete the "+ rpnt->r_addend" from the loop.

2004-12-11That last patch had some garbage in it... PIC != PIEEric Andersen
2004-12-11Partial commit of a patch from Alexandre Oliva:Eric Andersen
Here's an updated version of the patch I posted about a month ago. It leaves -nostdinc alone, and uses -print-file-name=include instead of -print-search-dirs to figure out where GCC's internal headers are. Please let me know whether there are any portions of this patch you'd like me to break into smaller pieces, to rework, or to give up trying to get into uClibc :-) Thanks,
2004-11-17Add BIND NOW support to MIPS.Joakim Tjernlund
Mips did not honour the LD_BIND_NOW env. variable or the DT_BIND_NOW flag in the dynamic section.
2004-11-10Add RTLD_LOCAL support for dlopened libs. Reported byJoakim Tjernlund
Andrew de Quincey, who has been most helpful getting this sorted out, thanks. Thanks also to Peter Mazinger who did alot of testing. Removed all traces of dl_parse_copy_information() since it is no longer used.
2004-11-02- Remove dynamic_size from struct elf_resolve.Joakim Tjernlund
- Replace all open coded dynamic handling with a function. Reduces size. - Fold special MIPS dynamic code into the dynamic_info item. - Add RELRO support. - Support linking with "-z now". - prepare for DT_RELACOUNT/DT_RELCOUNT optimization. - Add -z now to ld.so linking, this is what ld.so does anyway so let the linker know that.
2004-10-27Jocke's patch was almost right. Just needed move the DT_MIPS_RLD_MAP testManuel Novoa III
up a bit. Native and remote debugging of shared libs and threaded apps now works on mips.
2004-10-14unmap ld.so.cache when dlopen() returns.Joakim Tjernlund
2004-10-14Don't SEGV if library not found.Joakim Tjernlund
2004-10-12Mark Rakes writes:Joakim Tjernlund
without LDSO_CACHE_SUPPORT turned on, LDSO_CONF and LDSO_CACHE are not defined anywhere, but still used by ldconfig.c This patch allows ldconfig to build again, although there may be a cleaner way to fix this???? Applied with minor modification.
2004-10-11Undo previous change. Leave SUID programs alone until I know what to doJoakim Tjernlund
with them.
2004-10-11Don't use ld.so.cache for SUID programs.Joakim Tjernlund
2004-10-07Remove _dl_parse_copy_information() for CRIS per Peter Kjellerstedts request.Joakim Tjernlund
2004-10-07Remove usage of _dl_parse_copy_information() from generic code.Joakim Tjernlund
Remove definition of _dl_parse_copy_information() for powerpc. Remaining archs can do the same. Make debugging output of "relocation processing: xxx" a bit more sane.
2004-10-06Don't complain if ld.so.cache is missing.Joakim Tjernlund
2004-10-06Peter S. Mazinger writes:Joakim Tjernlund
Hello! Here is the modified unsecvars patch that applies to cvs.
2004-10-06Puts common defines into dl-defs.h (in ldso/include) from dl-elf.h andJoakim Tjernlund
dl-cache.h and make use of it. Also disables the lib-path-redundancy check for the case the cache is not used. Makes use of _PRELOAD_FILE_SUPPORT. From Peter Mazinger.
2004-10-06Remove unneeded -D<somedefine>, and use instead #ifdef __somedefine__Joakim Tjernlund
From Peter Mazinger.
2004-10-05Peter Kjellerstedt writes:Joakim Tjernlund
After the addition of a configuration option for enabling the support of /etc/ld.so.cache, I thought it might be a good idea to add one for the support of the /etc/ld.so.preload file too. So here it is. While doing this, I also noticed that the dynamic linker would hang indefinitely if either LD_PRELOAD or /etc/ld.so.preload contained a library which was already loaded, so I made a patch for that too. And of course, I could not resist from doing a little clean up of comments and indentation, so here is a patch for that too.
2004-10-03This patch from Mike Frysinger, extended from an earlier patch from Peter S.Eric Andersen
Mazinger implements the changes suggested by me on the uclibc list.

2004-09-28Remove /usr/X11R6/lib from search path.Joakim Tjernlund
Search in UCLIBC_RUNTIME_PREFIX"lib" before UCLIBC_RUNTIME_PREFIX"usr/lib". X11 users should enable USE_CACHE in Rules.mak, add /usr/X11R6/lib to /etc/ld.so.conf and run ldconfig.
2004-09-23Don't allow undefined global symbols to pass.Joakim Tjernlund
Move COPY relocs back to _dl_do_reloc(). White space cleanup.

2004-09-23Make powerpc look more like the other archs.Joakim Tjernlund
2004-09-17Added back dl_iterate_phdr in ldso(with some small changes).Joakim Tjernlund
Someone needs to test if it works to build and run gcj.
