* Rely on HP_TIMING_AVAIL implies HP_SMALL_TIMING_AVAILRichard Henderson2014-07-031-13/+5
|
* Remove HP_TIMING_DIFF_INIT and dl_hp_timing_overheadRichard Henderson2014-07-031-3/+0
| | | | | Without HP_TIMING_ACCUM, dl_hp_timing_overhead is write-only. If we remove it, there's no point in HP_TIMING_DIFF_INIT either.

* BZ #16613: Support TLS in audit libraries.Carlos O'Donell2014-02-251-1/+6
| | | | | | | | | | | This commit fixes a bug where the dynamic loader would crash when loading audit libraries, via LD_AUDIT, where those libraries used TLS. The dynamic loader was not considering that the audit libraries would use TLS and failed to bump the TLS generation counter leaving TLS usage inconsistent after loading the audit libraries. https://sourceware.org/ml/libc-alpha/2014-02/msg00569.html

* Avoid crashing in LD_DEBUG when program name is unavailableSiddhesh Poyarekar2013-05-291-8/+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.

* rtld: limit self loading check to normal mode onlyDmitry V. Levin2012-09-191-1/+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.
* Fix lots of bitrot for stub configurations.Roland McGrath2012-07-301-0/+2

* Add SystemTap static probes to the runtime linker. [BZ #14298]Gary Benson2012-07-271-0/+3
|
* Fix invalid memory access in do_lookup_x.Andreas Schwab2012-06-221-0/+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.
* Use _dl_fatal_printf instead of a private variant.Roland McGrath2012-05-141-1/+1
|
* New ld.so argument --inhibit-ldcache to disable ld.so.cache lookupSiddhesh Poyarekar2012-04-111-0/+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.
* Fix DL_DEBUG_UNUSED to elide the VDSO and handle PLT references properly.David S. Miller2012-04-051-1/+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.

* Remove last use of USE___THREADAndreas Schwab2011-09-121-135/+3
|
* Simplify malloc initializationUlrich Drepper2011-09-101-0/+1
| | | | | | Singificantly reduce the code needed at malloc initialization. In the process getpagesize is simplified by always initializing GLRO(dl_pagesize).
* Relocate objects in dependency orderAndreas Schwab2011-08-301-8/+4
|
* 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.
* Warning patrol.Roland McGrath2011-08-141-1/+1
|
* Implement LD_DEBUG=scopesUlrich Drepper2011-08-131-2/+14
