2013-05-29Avoid crashing in LD_DEBUG when program name is unavailableSiddhesh Poyarekar1-8/+5
Resolves: #15465 The program name may be unavailable if the user application tampers with argc and argv[]. Some parts of the dynamic linker caters for this while others don't, so this patch consolidates the check and fallback into a single macro and updates all users.

2012-09-19rtld: limit self loading check to normal mode onlyDmitry V. Levin1-1/+2
Commit glibc-2.14~10 disallowed rtld self loading to avoid a segfault that used to happen when rtld was loading itself in normal mode. Unfortunately, that commit disallowed all modes of self loading, including those that used to work before. This change limits the check for self loading to normal mode only, so that instruments like ldd could handle rtld properly.
2012-07-30Fix lots of bitrot for stub configurations.Roland McGrath1-0/+2
2012-07-27Add SystemTap static probes to the runtime linker. [BZ #14298]Gary Benson1-0/+3
2012-06-22Fix invalid memory access in do_lookup_x.Andreas Schwab1-0/+2
[BZ #13579] Do not free l_initfini and allow it to be reused on subsequent dl_open calls for the same library. This fixes the invalid memory access in do_lookup_x when the previously free'd l_initfini was accessed through l_searchlist when a library had been opened for the second time.
2012-05-14Use _dl_fatal_printf instead of a private variant.Roland McGrath1-1/+1
2012-04-11New ld.so argument --inhibit-ldcache to disable ld.so.cache lookupSiddhesh Poyarekar1-0/+9
It may sometimes be desirable to make the dynamic linker only pick up libraries from the library path and rpath and not look at the ld.so.cache that ldconfig generates. An example of such a use case is the glibc testsuite where the dynamic linker must not be influenced by any external paths or caches. This change adds a new option --inhibit-ldcache that when used, tells the dynamic linker to not use ld.so.cache even if it is available.
2012-04-05Fix DL_DEBUG_UNUSED to elide the VDSO and handle PLT references properly.David S. Miller1-1/+14
* elf/rtld.c (dl_main): If DL_DEBUG_UNUSED is enabled, turn off lazy binding. * elf/dl-lookup (_dl_lookup_symbol_x): If DL_DEBUG_UNUSED, ignore undefined symbol errors. * elf/rtlc.c (dl_main): Skip VDSO when checking for unused DT_NEEDED entries.

2011-09-10Simplify malloc initializationUlrich Drepper1-0/+1
Singificantly reduce the code needed at malloc initialization. In the process getpagesize is simplified by always initializing GLRO(dl_pagesize).
2011-08-30Relocate objects in dependency orderAndreas Schwab1-8/+4
2011-08-16Improve printing of lookup scopesUlrich Drepper1-1/+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.

2010-01-15ld.so: Adjust the auxv if ld.so is directly invoked.Andreas Krebbel1-11/+30
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.
2009-07-09Implement STB_GNU_UNIQUE handling.Ulrich Drepper1-1/+6
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.
