Andreas Arnez	f315524e03	* elf/setup-vdso.h (setup_vdso): Fix missing string termination.	2013-08-20 14:03:04 +02:00
Ryan S. Arnold	1ae8bfe07c	Add GLRO(dl_hwcap2) for new AT_HWCAP2 auxv_t a_type.	2013-06-28 16:50:48 -05:00
Pierre Ynard	0432680e8c	Test for mprotect failure in dl-load.c (bug 12492).	2013-06-28 21:43:42 +00:00
Nathan Froyd	ce61a2ad2e	Mark packed structure element used with atomic operation aligned.	2013-06-28 21:42:19 +00:00
Maciej W. Rozycki	f91f1c0fb8	[BZ #15022 ] Correct global-scope dlopen issues in static executables. 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.	2013-06-28 16:22:20 +01:00
Maciej W. Rozycki	b003710377	[BZ #15022 ] Avoid repeated calls to DL_STATIC_INIT for the same module.	2013-06-26 19:14:29 +01:00
Ryan S. Arnold	c18c701d03	Add AT_HWCAP2 as a new auxv_t a_type to elf.h.	2013-06-26 08:50:20 -05:00

Roland McGrath	bfcacbdec0	Use rtld-CPPFLAGS in rtld-%.os rules for generated sources.	2013-06-18 16:29:25 -07:00
Roland McGrath	f4a29fba07	Don't let ld.so that failed its sanity check land in place.	2013-06-13 10:26:44 -07:00
Ondrej Bilka	350635a59a	Fix leading whitespaces.	2013-06-06 20:36:07 +02:00
Joseph Myers	9c84384cc1	Remove trailing whitespace.	2013-06-05 20:44:03 +00:00
Siddhesh Poyarekar	b937534868	Avoid crashing in LD_DEBUG when program name is unavailable 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.	2013-05-29 21:34:12 +05:30
Carlos O'Donell	13e23af76e	Update comments in ldconfig.c and dl-hwcaps.c. In dl-hwcaps.c the comment read that rounding was done to ElfW(Addr), but it's actually rounded to ElfW(Word). In ldconfig.c we make each comment a sentence and mention that the "tls" pseudo-hwcap is just for legacy installations where TLS was optional. --- 2013-05-22 Carlos O'Donell <carlos@redhat.com> * elf/ldconfig.c (is_hwcap_platform): Make comments full setences. (main): Mention "tls" pseudo-hwcap is legacy. * elf/dl-hwcaps.c (_dl_important_hwcaps): Correct rounding comment.	2013-05-22 23:22:36 -04:00
Ryan S. Arnold	e054f49430	Add #include <stdint.h> for uint[32\|64]_t usage (except installed headers).	2013-05-16 11:32:54 -05:00
Carlos O'Donell	141af660d8	Add comments to vDSO hwcap loading process. Loading of the vDSO pseudo-hwcap from the type 2 GNU note is a rather arcane and poorly documented process. Given that I had a chance to review this code today I thought I would add all of the things I had to lookup to verify the validity of the process. With a single .note.GNU the vDSO can register up to 64 flags, though in practice you are limited to 64 - _DL_FIRST_EXTRA bits which on x86 is 12 bits. The only use of this that I know of is in the Xen support in Linux where they use the 1st bit to indicate "nosegneg". I see "We use bit 1 to avoid bugs in some versions of glibc when bit 0 is used; the choice is otherwise arbitrary.", but no reference to a glibc bug anywhere. The code as-is should support bit zero, so we still have that free for future use. The kernel, glibc, and ld.so.cache must coordinate to ensure that bit values don't go too high and are used consistently. --- 2013-05-13 Carlos O'Donell <carlos@redhat.com> * elf/dl-hwcaps.c (_dl_important_hwcaps): Comment vDSO hwcap loading. * elf/ldconfig.c (is_hwcap_platform): Comment each hwcap check. (main): Comment "tls" pseudo-hwcap.	2013-05-14 00:06:35 -04:00
Florian Weimer	4c0fe6fe42	Use stat64 instead of stat in installed programs This ensures reliable operation on file systems with inode numbers which do not fit into 32 bits.	2013-05-10 11:42:17 +02:00
Carlos O'Donell	3612972234	Add more comments to dlclose() algorithm. The algorithm for scanning dependencies upon dlclose is less than immediately obvious. This patch adds two bits of comments that explain why you start the dependency search at l_initfini[1], and why you need to restart the search. --- 2013-05-09 Carlos O'Donell <carlos@redhat.com> * elf/dl-close.c (_dl_close_worker): Add comments.	2013-05-09 17:37:15 -04:00

Carlos O'Donell	7208a313b9	dl_open_worker: Memset all of seen array. The seen array was doubled in size recently, but the memset to clear the array was not adjusted. We adjust the memset to always be correct regardless of the size of seen. --- 2013-04-06 Carlos O'Donell <carlos@redhat.com> [BZ #15309] * elf/dl-open.c (dl_open_worker): memset all of seen array.	2013-04-06 17:00:02 -04:00

Carlos O'Donell	b39949d211	ARM: Support loading unmarked objects from cache. ARM now supports loading unmarked objects from the dynamic loader cache. Unmarked objects can be used with the hard-float or soft-float ABI.

Siddhesh Poyarekar	9c6ea9facb	Fix stack size and address inconsistency due to executable stack When a stack is marked executable due to loading a DSO that requires an executable stack, the logic tends to leave out a portion of stack after the first frame, thus causing a difference in the value returned by pthread_getattr_np before and after the stack is marked executable. It ought to be possible to fix this by marking the rest of the stack as executable too, but in the interest of marking as less of the stack as executable as possible, the path this fix takes is to make pthread_getattr_np also look at the first frame as the underflow end of the stack and compute size and stack top accordingly. The above happens only for the main process stack. NPTL thread stacks are not affected by this change.	2012-05-26 09:48:26 +05:30

Siddhesh Poyarekar	73d65cc378	New ld.so argument --inhibit-ldcache to disable ld.so.cache lookup 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.	2012-04-11 00:13:52 +05:30

Martin von Gagern	d26dfc60ed	Fix handling of static TLS in dlopen'ed objects When dynamically loading a library along with several dependencies, calls to _dl_add_to_slotinfo and _dl_update_slotinfo can become intermixed. As a consequence, _dl_update_slotinfo will update the generation counter of the dtv although not all of the slots belonging to that generation have been added. Subsequent calls to _dl_add_to_slotinfo will add more slots to the same generation, for which no storage will be allocated, as the dtv generation checks will claim no work is necessary. This will lead to uninitialized dtv entries and will likely cause a SIGSEGV when thread local variables are accessed.	2011-05-14 21:25:43 -04:00

When an AVX or SSE register value in pltenter is modified, we have to make sure that the SSE part value is the same in both lr_xmm and lr_vector fields so that pltexit will get the correct value from either lr_xmm or lr_vector fields. AVX-enabled pltenter should update both lr_xmm and lr_vector fields to support stacked AVX/SSE pltenter functions.	2009-08-08 10:54:42 -07:00

Ulrich Drepper	b48a267b8f	Preserve SSE registers in runtime relocations on x86-64. SSE registers are used for passing parameters and must be preserved in runtime relocations. This is inside ld.so enforced through the tests in tst-xmmymm.sh. But the malloc routines used after startup come from libc.so and can be arbitrarily complex. It's overkill to save the SSE registers all the time because of that. These calls are rare. Instead we save them on demand. The new infrastructure put in place in this patch makes this possible and efficient.	2009-07-29 08:33:03 -07:00

Jakub Jelinek	09cd1f5754	Fix STB_GNU_UNIQUE handling for > 30 unique symbols. There were several issues when the initial 31 entries hashtab filled up. size * 3 <= tab->n_elements is always false, table can't have more elements than its size. I assume from libiberty/hashtab.c this meant to be check for 3/4 full. Even after fixing that, _dl_higher_prime_number (31) apparently returns 31, only _dl_higher_prime_number (32) returns 61. And, size variable wasn't updated during reallocation, which means during reallocation the insertion of the new entry was done into a wrong spot. All this lead to a hang in ld.so, because a search with n_elements 31 size 31 wouldn't ever terminate.	2009-07-27 07:25:57 -07:00
