* Minor optimization of unloading prevention patch.Ulrich Drepper2009-07-231-5/+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.
* Fix comment.Ulrich Drepper2009-07-231-1/+1
|
* Some more fixes for the unique symbol handling.Ulrich Drepper2009-07-231-5/+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.
* Handle unloading of DSO with a unique symbol definition.Ulrich Drepper2009-07-232-5/+48
|
* Remove warning and little optimization.Ulrich Drepper2009-07-161-0/+1
| | | | | The prototype for _dl_higher_prime_number was missing. While at it, the function is now marked with internal_function.
* Fix build issue with modules for audit test on machines != x86-64.Ulrich Drepper2009-07-151-3/+5
|
* Add AVX support to ld.so auditing for x86-64.H.J. Lu2009-07-107-2/+554
|
* Remove do-lookup.h.Ulrich Drepper2009-07-103-388/+366
| | | | | It is not necessary/useful anymore to have the content separate from dl-lookup.c.
* Implement STB_GNU_UNIQUE handling.Ulrich Drepper2009-07-0911-11/+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.
* Define STB_GNU_UNIQUE.Ulrich Drepper2009-07-071-0/+1
|
* Clean up code for hash table handling in ld.so.Ulrich Drepper2009-07-071-0/+64

|
* Add more IFUNC tests.H.J. Lu2009-06-2218-5/+399
| | | | | Mostly tests around not-exported IFUNC functions, IFUNC in statically linked binaries and PIEs, etc.
* Use +link-pie Makefile rule to link PIE ifunc tests.H.J. Lu2009-06-171-16/+2
|
* Don't treat bug reporting message as a format string.Andreas Schwab2009-06-161-2/+2
|
* Consolidate PIE linking Makefile rules.H.J. Lu2009-06-161-8/+1
|
* libc part of prelink IFUNC support.Jakub Jelinek2009-06-151-6/+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.
* Test for ELF IFUNC functionality.H.J. Lu2009-06-0324-1/+627
|
* Terminate correct buffer.Ulrich Drepper2009-06-031-1/+1
| | | | Little typo could cause additional characters to be printed.
* Finish IFUNC support for x86 and x86-64.Ulrich Drepper2009-05-311-2/+4
| | | | Add support for the IRELAIVE relocation and IFUNC in static executables.
* Remove redundant .gitignore files.Andreas Schwab2009-05-161-6/+0
|
* rename each .cvsignore file to .gitignoreJim Meyering2009-05-151-0/+0
|
* Test DSOs for executable stack.Ulrich Drepper2009-05-152-2/+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.
