* Remove INTDEF / INTUSE / INTVARDEF (bug 14132).Joseph Myers2014-11-051-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Completing the removal of the obsolete INTDEF / INTUSE mechanism, this patch removes the final use - that for _dl_starting_up - replacing it by rtld_hidden_def / rtld_hidden_proto. Having removed the last use, the mechanism itself is also removed. Tested for x86_64 that installed stripped shared libraries are unchanged by the patch. (This is not much of a test since this variable is only defined and used in the !HAVE_INLINED_SYSCALLS case.) [BZ #14132] * include/libc-symbols.h (INTUSE): Remove macro. (INTDEF): Likewise. (INTVARDEF): Likewise. (_INTVARDEF): Likewise. (INTDEF2): Likewise. (INTVARDEF2): Likewise. * elf/rtld.c [!HAVE_INLINED_SYSCALLS] (_dl_starting_up): Use rtld_hidden_def instead of INTVARDEF. * sysdeps/generic/ldsodefs.h [IS_IN_rtld] (_dl_starting_up_internal): Remove declaration. (_dl_starting_up): Use rtld_hidden_proto. * elf/dl-init.c [!HAVE_INLINED_SYSCALLS] (_dl_starting_up): Remove declaration. [!HAVE_INLINED_SYSCALLS] (_dl_starting_up_internal): Likewise. (_dl_init) [!HAVE_INLINED_SYSCALLS]: Don't use INTUSE with _dl_starting_up. * elf/dl-writev.h (_dl_writev): Likewise. * sysdeps/powerpc/powerpc64/dl-machine.h [!HAVE_INLINED_SYSCALLS] (DL_STARTING_UP_DEF): Use __GI__dl_starting_up instead of _dl_starting_up_internal.
* Don't use INTDEF/INTUSE with _dl_mcount (bug 14132).Joseph Myers2014-11-051-1/+1
| | | | | | | | | | | | | | | | | | | Continuing the removal of the obsolete INTDEF / INTUSE mechanism, this patch replaces its use for _dl_mcount with use of rtld_hidden_def / rtld_hidden_proto. Tested for x86_64 that installed stripped shared libraries are unchanged by the patch. [BZ #14132] * elf/dl-profile.c (_dl_mcount): Use rtld_hidden_def instead of INTDEF. * sysdeps/generic/ldsodefs.h (_dl_mcount_internal): Remove declaration. (_dl_mcount): Use rtld_hidden_proto. * elf/dl-runtime.c (_dl_profile_fixup): Don't use INTUSE with _dl_mcount. * elf/rtld.c (_rtld_global_ro): Likewise.
* Don't use INTDEF/INTUSE with _dl_argv (bug 14132).Joseph Myers2014-11-041-20/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Continuing the removal of the obsolete INTDEF / INTUSE mechanism, this patch replaces its use for _dl_argv with rtld_hidden_data_def and rtld_hidden_proto. Some places in .S files that previously used _dl_argv_internal or INTUSE(_dl_argv) now use __GI__dl_argv directly (there are plenty of existing examples of such direct use of __GI_*). A single place in rtld.c previously used _dl_argv without INTUSE, apparently accidentally, while the rtld_hidden_proto mechanism avoids such accidential omissions. As a consequence, this patch *does* change the contents of stripped ld.so. However, the installed stripped shared libraries are identical to those you get if instead of this patch you change that single _dl_argv use to use INTUSE, without any other changes. Tested for x86_64 (testsuite as well as comparison of installed stripped shared libraries as described above). [BZ #14132] * sysdeps/generic/ldsodefs.h (_dl_argv): Use rtld_hidden_proto. [IS_IN_rtld] (_dl_argv_internal): Do not declare. (rtld_progname): Make macro definition unconditional. * elf/rtld.c (_dl_argv): Use rtld_hidden_data_def instead of INTDEF. (dlmopen_doit): Do not use INTUSE with _dl_argv. (dl_main): Likewise. * elf/dl-sysdep.c (_dl_sysdep_start): Likewise. * sysdeps/alpha/dl-machine.h (RTLD_START): Use __GI__dl_argv instead of _dl_argv_internal. * sysdeps/powerpc/powerpc32/dl-start.S (_dl_start_user): Use __GI__dl_argv instead of INTUSE(_dl_argv). * sysdeps/powerpc/powerpc64/dl-machine.h (RTLD_START): Use __GI__dl_argv instead of _dl_argv_internal.

* 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 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.

* 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.
