| | | | | | | | | 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.

| | | | | | 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.

| | | | | | Hello! Here is the modified unsecvars patch that applies to cvs.

| | | | | | | | | | | | | | | | 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.
* This patch from Mike Frysinger, extended from an earlier patch from Peter S.Eric Andersen2004-10-035-15/+13

* Remove /usr/X11R6/lib from search path.Joakim Tjernlund2004-09-281-5/+2
| | | | | | | | 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.

* Bugfix: Add r_addend to final address. The r_addend is mostly zeroJoakim Tjernlund2004-09-171-8/+6
| | | | | | | but can be nonzero for JMP relocs as well. All Rela arches need to do this, test and send a patch :) Remove unneeded test in R_PPC_COPY.
* Don't allow undefined global symbols to pass(all archs needs fixing,Joakim Tjernlund2004-09-171-10/+16
| | | | | | | | | | | but powerpc). If you are using buildroot and soft floating point, you may have to rebuild the libm.so library, copy it to staging_dir/lib and rebuild your application. Move handling of R_386_COPY back into _dl_do_reloc(all archs should do this). Adjust the first argument to _dl_memcpy as it looks wrong to have symtab[symtab_index].st_value as destination for the mem copy.

* #include "dl-startup.c into ldso.c, making ldso one compilation unit.Joakim Tjernlund2004-08-272-2/+3
| | | | | | | | | | | | Now all functions and vaiables can be made static to reduce relocs. Basicly, all variables should be merged into one struct variable and then export that struct. Exported functions should be exported as functions pointers in the above struct. This will reduce the number of relocs inside ldso to a handful. Add -Bsymbolic to linker for ldso. This will resolve all functions (all JMP_SLOT goes away) and the remaining relocs are transformed into RELATIVE relocs.

| | | | | | | | | | | | | | | misread this code and removed it, sorry. I printed the values of _dl_brkp and _dl_envp in ldso and got this when executing: ls: __curbrk: 0x300c16e0 __environ: 0x1008372c ldd: __curbrk: 0x300776e0 __environ: 0x3007759c why is__environ in the app when executing ls but not ldd?

* Let ldso find libc's malloc function and set _dl_malloc_function.Joakim Tjernlund2004-08-262-10/+4

* Relocations of the application's global GOT entries were not being run, andEric Andersen2004-08-263-78/+44
| | | | | | | | only the global GOT entry relocations for the loaded shared libs were being handled. This made applications segfault when using un-fixedup symbols. After many hours debugging to track down the problem, this patch makes the mips port happy again. -Erik

| | | | | | | | | | | | "I fixed the _dl_parse_copy_information in the same way than for the powerpc and it works fine for me. You may luck at the patch for the powerpc/elfinterp.c, where I change the paramter of a dl_dprintf statement. Now we use the same parameters than for the relocation copy." Arch mantainers, please do the same. When all arches has been fixed, we can remove of _dl_parse_copy_information, it is just a waste of CPU cycles.

| | | | | | | | | | | | | | Hi Manuel & Erik I think I know why MIPS is broken. _dl_perform_mips_global_got_relocations() is broken. It will due to my latest changes reloctate ldso. This function needs to die and its job should be done inside _dl_parse_relocation_information(). It is mostly a copy and paste job, Also PERFORM_BOOTSTRAP_GOT and PERFORM_BOOTSTRAP_RELOCATION should be fixed, they use symbols which aren't passed as arguments. Jocke
