* Improve printing of lookup scopesUlrich Drepper2011-08-161-1/+1
| | | | | | The scope of a new object should be printed earlier and when the scope of an already loaded object is extended only the changes should be printed.

* Don't deadlock in __dl_iterate_phdr while (un)loading objects.Andreas Schwab2010-05-031-0/+4
|
* Mark _dl_random attribute_relro in the header file.Richard Henderson2010-03-261-1/+1
| | | | | | | | It's already so marked in dl-sysdep.c. Failure to so mark in the header file leads the compiler to believe that the variable should be addressable via the .sdata section. Signed-off-by: Richard Henderson <rth@twiddle.net>
* ld.so: Adjust the auxv if ld.so is directly invoked.Andreas Krebbel2010-01-151-2/+3
| | | | | | | | If a binary gets invoked by passing it as argument to ld.so the stack still holds the auxiliary vector of ld.so when entering the _start routine of the executable. So the invocation via ld.so is not fully transparent to the executable. This causes problems if the executable wants to scan the auxv itself.
* Define IPTOS_CLASS_* macros according to RFC 2474.Philip Prindeville2010-01-141-12/+31

|
* Replace hand-coded unwind tables from x86-64 pthread_once.Ulrich Drepper2009-07-171-7/+36
|
* Remove warning and little optimization.Ulrich Drepper2009-07-161-0/+4
| | | | | The prototype for _dl_higher_prime_number was missing. While at it, the function is now marked with internal_function.
* Implement STB_GNU_UNIQUE handling.Ulrich Drepper2009-07-091-0/+15
| | | | | | | | | 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.
* Extend pt_chown to drop privileges.Ulrich Drepper2009-06-161-2/+3
| | | | | | If libcap is available, use it to drop privileges in pt_chown before starting the work to change the permissions and ownership of the slave device.
* Finish IFUNC support for x86 and x86-64.Ulrich Drepper2009-05-311-0/+23
| | | | Add support for the IRELAIVE relocation and IFUNC in static executables.
