2009-07-27Fix STB_GNU_UNIQUE handling for > 30 unique symbols.Jakub Jelinek1-2/+3
There were several issues when the initial 31 entries hashtab filled up. size * 3 <= tab->n_elements is always false, table can't have more elements than its size. I assume from libiberty/hashtab.c this meant to be check for 3/4 full. Even after fixing that, _dl_higher_prime_number (31) apparently returns 31, only _dl_higher_prime_number (32) returns 61. And, size variable wasn't updated during reallocation, which means during reallocation the insertion of the new entry was done into a wrong spot. All this lead to a hang in ld.so, because a search with n_elements 31 size 31 wouldn't ever terminate.
2009-07-26Define NT_GNU_GOLD_VERSION.Ulrich Drepper1-0/+3
2009-07-23Minor optimization of unloading prevention patch.Ulrich Drepper1-5/+5
References to unique symbols from copy relocations can only come from executables which cannot be unloaded anyway. Optimize the code to set the unload flag a bit.
2009-07-23Fix comment.Ulrich Drepper1-1/+1
2009-07-23Some more fixes for the unique symbol handling.Ulrich Drepper1-5/+4
The hash value can be zero, so we need a different test for empty slots. And unify the way we prevent a DSO from being unloaded.
2009-07-23Handle unloading of DSO with a unique symbol definition.Ulrich Drepper2-5/+48
2009-07-16Remove warning and little optimization.Ulrich Drepper1-0/+1
The prototype for _dl_higher_prime_number was missing. While at it, the function is now marked with internal_function.
2009-07-15Fix build issue with modules for audit test on machines != x86-64.Ulrich Drepper1-3/+5
2009-07-10Add AVX support to ld.so auditing for x86-64.H.J. Lu7-2/+554
2009-07-10Remove do-lookup.h.Ulrich Drepper3-388/+366
It is not necessary/useful anymore to have the content separate from dl-lookup.c.
2009-07-09Implement STB_GNU_UNIQUE handling.Ulrich Drepper11-11/+291
Some symbols have to be identified process-wide by their name. This is particularly important for some C++ features (e.g., class local static data and static variables in inline functions). This cannot completely be implemented with ELF functionality so far. The STB_GNU_UNIQUE binding helps by ensuring the dynamic linker will always use the same definition for all symbols with the same name and this binding.

2009-06-15libc part of prelink IFUNC support.Jakub Jelinek1-6/+11
The dl-lookup.c changes are needed for prelink (support in prelink checked into SVN, tested for both i?86 and x86-64), dl-irel.h just something I discovered by code inspection.
2009-06-03Test for ELF IFUNC functionality.H.J. Lu24-1/+627
2009-06-03Terminate correct buffer.Ulrich Drepper1-1/+1
Little typo could cause additional characters to be printed.

2009-05-15Test DSOs for executable stack.Ulrich Drepper2-2/+170
Add a text program, built to run on the host, to check all newly built DSOs for executable stacks and fail if the stack information is missing or indicates executable stacks.
