2009-07-23Minor optimization of unloading prevention patch.Ulrich Drepper
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 Drepper
2009-07-23Some more fixes for the unique symbol handling.Ulrich Drepper
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 Drepper
2009-07-16Remove warning and little optimization.Ulrich Drepper
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 Drepper
2009-07-10Add AVX support to ld.so auditing for x86-64.H.J. Lu
2009-07-10Remove do-lookup.h.Ulrich Drepper
It is not necessary/useful anymore to have the content separate from dl-lookup.c.
2009-07-09Implement STB_GNU_UNIQUE handling.Ulrich Drepper
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.

2009-07-07Clean up code for hash table handling in ld.so.Ulrich Drepper

2009-06-22Clean up whitespaces in last patch.Ulrich Drepper
2009-06-22Add more IFUNC tests.H.J. Lu
Mostly tests around not-exported IFUNC functions, IFUNC in statically linked binaries and PIEs, etc.
2009-06-17Use +link-pie Makefile rule to link PIE ifunc tests.H.J. Lu
2009-06-16Don't treat bug reporting message as a format string.Andreas Schwab
2009-06-16Consolidate PIE linking Makefile rules.H.J. Lu
2009-06-15libc part of prelink IFUNC support.Jakub Jelinek
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. Lu
2009-06-03Terminate correct buffer.Ulrich Drepper
Little typo could cause additional characters to be printed.
2009-05-31Finish IFUNC support for x86 and x86-64.Ulrich Drepper
Add support for the IRELAIVE relocation and IFUNC in static executables.
2009-05-16Remove redundant .gitignore files.Andreas Schwab
2009-05-15rename each .cvsignore file to .gitignoreJim Meyering
2009-05-15Test DSOs for executable stack.Ulrich Drepper
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.
