| 2009-07-21 | Minor cleanups in x86-64 strstr. | Ulrich Drepper | |
| 2009-07-20 | Better check for optimization in new x86-64 strstr/strcasestr. | Ulrich Drepper | |
| 2009-07-20 | SSE4.2 strstr/strcasestr for x86-64. | H.J. Lu | |
| This patch implements SSE4.2 strstr/strcasestr, using Knuth-Morris-Pratt string searching algorithm. | |||
| 2009-07-20 | Use correct index for _NL_CTYPE_NONASCII_CASE. | Ulrich Drepper | |
| 2009-07-20 | Check generated locale for non-ASCII 8-bit characters with case conversion. | Ulrich Drepper | |
| If a locale does not have 8-bit characters with case conversion which are different from the ASCII conversion (±0x20) then we can perform some optimizations. These will follow later. | |||
| 2009-07-20 | Minor optimizations of last x86-64 condvar changes. | Ulrich Drepper | |
| 2009-07-19 | Support requeueing for condvars using PI mutex. x86-64 only. | Ulrich Drepper | |
| Add support for the new FUTEX_WAIT_REQUEUE_PI and FUTEX_CMP_REQUEUE_PI options of futex. | |||
| 2009-07-19 | Make x86-64 pthread_cond_timedwait more robust. | Ulrich Drepper | |
| It just happens that __pthread_enable_asynccancel doesn't modify the $rdi register. But this isn't guaranteed. Hence we reload the register after the calls. | |||

| 2009-07-18 | Optimize x86-64 pthread_cond_timedwait. | Ulrich Drepper | |
| Instead of actively registering an unwind buffer we now use the exception handling functionality of the gcc runtime. | |||

| 2009-07-17 | Revert "Fix lock handling in memory hander of nscd." | Ulrich Drepper | |
| This reverts commit 137028b4d7e50f71906c1656c27079eac5a1d085. Conflicts: ChangeLog | |||
| 2009-07-17 | Add missing BZ number in ChangeLog. | Ulrich Drepper | |
| 2009-07-16 | Handle overly large answer buffers in resolver. | Ulrich Drepper | |
| In EDNS0 records the maximum result size is transmitted in a 16 bit value. Large buffer sizes were handled incorrectly by using only the low 16 bits. Fix this by limiting the size to 0xffff. | |||
| 2009-07-16 | Fix lock handling in memory hander of nscd. | Petr Baudis | |
| The commit 20e498bd removes the pthread_mutex_rdlock() calls, but not the corresponding pthread_mutex_unlock() calls. Also, the database lock is never unlocked in one branch of the mempool_alloc() if. I think unreproducible random assert(dh->usable) crashes in prune_cache() were caused by this. But an easy way to make nscd threads hang with the broken locking was. | |||
| 2009-07-16 | Use correct release semantic in list update. | Andreas Schwab | |
| nscd uses lockfree lists and we need to ensure the correct release semantics is used when adding to the list. | |||
| 2009-07-16 | Fix race in corruption check. | Ulrich Drepper | |
| With atomic fastbins the checks performed can race with concurrent modifications of the arena. If we detect a problem re-do the test after getting the lock. | |||
| 2009-07-16 | Use rel semantics of cas instead of acq semantics with full barrier before ↵ | Jakub Jelinek | |
| it in _int_free The following patch fixes catomic_compare_and_exchange_*_rel definitions (which were never used and weren't correct) and uses catomic_compare_and_exchange_val_rel in _int_free. Comparing to the pre-2009-07-02 --enable-experimental-malloc state the generated code should be identical on all arches other than ppc/ppc64 and on ppc/ppc64 should use lwsync instead of isync barrier. | |||
| 2009-07-16 | Remove warning and little optimization. | Ulrich Drepper | |
| The prototype for _dl_higher_prime_number was missing. While at it, the function is now marked with internal_function. | |||
| 2009-07-16 | Optimize restoring of ymm registers on x86-64. | Ulrich Drepper | |
| The patch mainly reduces the code size but also avoids some jumps. | |||
| 2009-07-16 | Fix up whitespaces in new memcmp for x86-64. | Ulrich Drepper | |
| 2009-07-16 | memcmp implementation for x86-64 using SSE2. | H.J. Lu | |
| 2009-07-15 | Fix thinko in AVX audit patch. | Ulrich Drepper | |
| Don't use AVX instructions too often. | |||
| 2009-07-15 | Fix typo in last change. | Ulrich Drepper | |
| 2009-07-15 | Secure AVX changes for auditing code. | Ulrich Drepper | |
| The original AVX patch used a function pointer to handle the difference between machines with and without AVX support. This is insecure. A well-placed memory exploit could lead to redirection of the execution. Using a variable and several tests is a bit slower but cannot be exploited in this way. | |||
| 2009-07-15 | Fix build issue with modules for audit test on machines != x86-64. | Ulrich Drepper | |
| 2009-07-10 | Add AVX support to ld.so auditing for x86-64. | H.J. Lu | |
| 2009-07-10 | Remove do-lookup.h. | Ulrich Drepper | |
| It is not necessary/useful anymore to have the content separate from dl-lookup.c. | |||
| 2009-07-10 | Fix comment in Linux's <sys/epoll.h>. | Ulrich Drepper | |
| 2009-07-09 | Implement STB_GNU_UNIQUE handling. | Ulrich Drepper | |
| 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. | |||
| 2009-07-07 | Define STB_GNU_UNIQUE. | Ulrich Drepper | |
| 2009-07-07 | Clean up code for hash table handling in ld.so. | Ulrich Drepper | |
| 2009-07-06 | Optimize test for valid ELF symbol types in lookup function. | Ulrich Drepper | |
| 2009-07-05 | Fix wrong PPC_FEATURE_* values. | Andreas Schwab | |
| Nothing uses these wrong values yet, but it fixes a warning due to conflicting definitions in <asm/cputable.h>. | |||
| 2009-07-03 | Minor cleanups in recently added files. | Ulrich Drepper | |
| 2009-07-03 | Align functions to 16-byte boundary. | Ulrich Drepper | |
| Some of the new multi-arch string functions for x86-64 were not aligned to 16 byte boundarie,s possibly creating unnecessary cache line misses and delays. | |||
