* BZ #15536: Fix ulp for 128-bit IBM long double.Carlos O'Donell2013-06-033-12/+35
| | | | | | | | In 128-bit IBM long double the precision of the type decreases as you approach subnormal numbers, equaling that of a double for subnormal numbers. Therefore adjust the computation in ulp to use 2^(MIN_EXP - MANT_DIG) which is correct for FP_SUBNORMAL for all types.
* Revert po and pot files changes.Carlos O'Donell2013-05-314-3/+9
| | | | | Upstream TP should modify PO files and POT file should be empty template.

* Set reasonable limits for xdr_requests.Patsy Franklin2013-05-303-7/+26
| | | | | [BZ #15553] Increased the current limits large enough to load large key and data values, but small enough to not pose a DoS threat.
* [BZ #14256]Jeff Law2013-05-304-20/+29
| | | | | | * manual/errno.texi (ESTALE): Update to account for more than just NFS file systems. * sysdeps/gnu/errlist.c: Regenerated.
* Avoid crashing in LD_DEBUG when program name is unavailableSiddhesh Poyarekar2013-05-2941-103/+220
| | | | | | | | | 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.

* Add descriptive titles to po files and header.Carlos O'Donell2013-05-284-3/+9
| | | | | | | | | | | | | | Added descriptive titles to the Belarusian, English (American), and Chinese (simplified) po/pot files. --- 2013-05-28 Carlos O'Donell <carlos@redhat.com> * po/be.po: Add descriptive title. * po/zh_CN.po: Likewise. * po/header.pot: Likewise.
* localedef: include file name in error messagesMike Frysinger2013-05-252-2/+8
| | | | | | | | | | When mkstemp fails, the error message the user gets back is: cannot create temporary file: No such file or directory That isn't terribly useful in figuring out why, so include the full filename we tried to create in the error output.

| | | | | This patch add inline functions to change the Program Priority Register from ISA 2.05.
* Correctly compute ulp near zero.Carlos O'Donell2013-05-242-48/+103
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current value used for ulp near zero is wrong, and this commit fixes it such that ulp(0) is the smallest subnormal value nearest to zero, which makes the most sense for testing values near zero. Note that this is not what Java does; they use the nearest normal value, which is less accurate than what we want for glibc. Note that there is no correct implementation of ulp since there is no strict mathmatical definition that is accepted by all groups using IEEE 754. Previously with the large ulp values near zero there were tests that previously passed, but were in fact billions of ulp away from the precise answer. With this commit we now need to disable one of the cpow tests which is revealed to be inaccurate (bug 14473). --- 2013-05-24 Carlos O'Donell <carlos@redhat.com> * math/libm-test.inc (MAX_EXP): Define. (ULPDIFF): Define. (ulp): New function. (check_float_internal): Use ULPDIFF. (cpow_test): Disable failing test. (check_ulp): Test ulp() implemetnation. (main): Call check_ulp before starting tests.
* tile: improve detection for missing -mcmodel=large supportChris Metcalf2013-05-244-4/+41
| | | | | | | | | | | | | The existing test avoided passing -mcmodel=large if the compiler didn't support it. However, we need to test not just the compiler support, but also the toolchain (as and ld) support, so make the test more complete. In addition, we have to avoid using the hwN_plt() assembly operators if that support is missing, so guard the uses with #ifdef NO_PLT_PCREL. This allows us to properly build glibc with the current community binutils, which doesn't yet have the PC-relative PLT operator support. The -mcmodel=large support is in gcc 4.8, but the toolchain support won't be present in the community until binutils 2.24.

* Initialize wide struct info.Ondrej Bilka2013-05-243-3/+12
| | | | | | | | Fixes 15381. Using wide character function is on byte oriented memstream is undefined behaviour. This behaviour was masked by not initializing wide struct info. We now initialize it to cause a predictable crash.

* Update comments in ldconfig.c and dl-hwcaps.c.Carlos O'Donell2013-05-223-8/+16
| | | | | | | | | | | | | | | | | 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.

| | | | | | Adds new SIGBUS error codes for hardware poison signals, syncing with the current kernel headers (v3.9). It also adds si_trapno field for alpha.
* Fix _nl_find_msg malloc failure case, and callers.Carlos O'Donell2013-05-224-7/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes two issues, and perhaps should be two distinct commits, but I present it here as one for the sake of completeness. Commit 006dd86111c44572dbd3b26e9c63dd0f834d7762 fails to check malloc's return in intl/dcigettext.c (_nl_find_msg): ~~~ freemem_size = INITIAL_BLOCK_SIZE; newmem = (transmem_block_t *) malloc (freemem_size); ... newmem->next = transmem_list; transmem_list = newmem; ~~~ If malloc fails then newmem is NULL then newmem->next results in a fault. The fix is easy enough, check for newmem != NULL, and fall through to the error condition below which returns (char *) -1 e.g. resource error. The problem is that returning (char *) -1 will break all sorts of other code, so while what we did is correct, the real failure case fix is slightly broader. There are 4 other places where _nl_find_msg is called, one is OK, the other three are fixed to handle -1 error return value. No regressions on x86-64 or x86. However, no regressions isn't really a useful metric for this code. The change was tested as documented here: http://sourceware.org/glibc/wiki/Testing/WhiteBox using SystemTap for fault injection to simulate malloc failure. --- 2013-05-03 Carlos O'Donell <carlos at redhat.com> [BZ #15441] * intl/dcigettext.c (DCIGETTEXT): Skip translating if _nl_find_msg returns -1. (_nl_find_msg): Return -1 if recursive call returned -1. If newmem is null return -1. * intl/loadmsgcat.c (_nl_load_domain): If _nl_find_msg returns -1 abort loading the domain.

* Test getaddrinfo return valueDmitry V. Levin2013-05-213-1/+74
| | | | | | This helps testing for regression of BZ#15339. Creation of network isolated environments is a privileged operation and therefore is not included to the test.
* Set EAI_SYSTEM only when h_errno is NETDB_INTERNALSiddhesh Poyarekar2013-05-214-10/+26
| | | | | | | | | | | | Fixes BZ #15339. NSS_STATUS_UNAVAIL may mean that a necessary input resource is not available. This could occur in a number of cases including when the network is down, system runs out of file descriptors, etc. The correct differentiator in such a case is the h_errno, which gives the nature of failure. In case of failures other than a simple 'not found', we set h_errno as NETDB_INTERNAL and let errno be the identifier for the exact error.

* Faster memset on x64Ondrej Bilka2013-05-202-1315/+96
| | | | | | | | | This implementation speed up memset in several ways. First is avoiding expensive computed jump. Second is using fact that arguments of memset are most of time aligned to 8 bytes. Benchmark results on: kam.mff.cuni.cz/~ondra/benchmark_string/memset_profile_result27_04_13.tar.bz2
* Faster memcpy on x64.Ondrej Bilka2013-05-205-8/+195
| | | | | | | | | We add new memcpy version that uses unaligned loads which are fast on modern processors. This allows second improvement which is avoiding computed jump which is relatively expensive operation. Tests available here: http://kam.mff.cuni.cz/~ondra/memcpy_profile_result27_04_13.tar.bz2
