2013-12-02Return fixed version of breaking of RPATH when $ORIGIN contains colonsOndřej Bílka
2013-11-18Revert b75891075bece24be9fd85618f18af4a2daf7f1cOndřej Bílka
2013-11-18Fix breaking of RPATH when $ORIGIN contains colons. Fixes bug 10253Ondřej Bílka
We first expanded origin and then split string by colons. This misbehaves when $ORIGIN contain colon so we first split string, then expand $ORIGIN.

2013-06-28[BZ #15022] Correct global-scope dlopen issues in static executables.Maciej W. Rozycki
This change creates a link map in static executables to serve as the global search list for dlopen. It fixes a problem with the inability to access the global symbol object and a crash on an attempt to map a DSO into the global scope. Some code that has become dead after the addition of this link map is removed too and test cases are provided.
2013-05-29Avoid crashing in LD_DEBUG when program name is unavailableSiddhesh Poyarekar
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.

2013-01-02Update copyright notices with scripts/update-copyrights.Joseph Myers
2012-11-26Cast to __intptr_t before casting pointer to int64H.J. Lu
2012-10-30Invoke DL_AFTER_LOAD if definedChris Metcalf
This hook is useful for any arch-specific functionality that should be done on loaded objects. For the tile architecture, the hook is already provided (though we switch to using the new macro name with this commit) and implements a simulator notifier so that the simulator can load Elf symbols to match the object and generate better error messages for PC's. Also, remove a spurious definition of DL_UNMAP in dl-runtime.c
2012-10-20Retry read in ld.so if the entire ELF header is not read inSiddhesh Poyarekar
[BZ #13601] A read operation could return less than requested data for a number of reasons.

2012-07-27Add SystemTap static probes to the runtime linker. [BZ #14298]Gary Benson
2012-04-11New ld.so argument --inhibit-ldcache to disable ld.so.cache lookupSiddhesh Poyarekar
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.

2010-03-18Future safety in checking ELF header.Ulrich Drepper
If we should use further fields in the e_ident array in the ELF header of files we want zero to mean the default. Enforce zero for now so that non-optional features indicated by nonzero values are not go unnoticed when using an old dynamic linker.
2010-03-16Extended ELF ABI version handling only for Linux.Ulrich Drepper
If the OSABI is generic we should not allow the ABI version to be nonzero. Move all the new functionality into Linux-specific files.
