* New pthread_barrier algorithm to fulfill barrier destruction requirements.Torvald Riegel2016-01-1518-764/+419
| | | | | | | | | | The previous barrier implementation did not fulfill the POSIX requirements for when a barrier can be destroyed. Specifically, it was possible that threads that haven't noticed yet that their round is complete still access the barrier's memory, and that those accesses can happen after the barrier has been legally destroyed. The new algorithm does not have this issue, and it avoids using a lock internally.
* Fix race in tst-mqueue5Paul E. Murphy2016-01-152-2/+24
| | | | | | | | | | | | | | | | | The check is done on line 117 by a thread spawned from do_child(), forked from do_test(). This test generates a signal in the forked process. Either thread may handle the signal, and on ppc, it happens to be done on do_child, on the thread which is not doing the check on line 117. This exposes a race condition whereby the test incorrectly fails as the signal is caught during or after the check. This is mitigated by ensuring the signal is blocked in the child thread while thread is running.
* Have iconv accept redundant escape sequences in IBM900, IBM903, IBM905,Martin Sebor2016-01-158-61/+136
| | | | | | | | | | | | | | | | | | IBM907, and IBM909. Patch for bug #17197 changes the encoder to avoid generating redundant shift sequences. However, those sequences may already be present in data encododed by prior versions of the encoder. This change modifies the decoder to also avoid rejecting redundant shift sequences. [BZ #19432] * iconvdata/Makefile: Add bug-iconv11. * iconvdata/bug-iconv11.c: New test. * iconvdata/ibm930.c: Do not reject redundant shift sequences. * iconvdata/ibm933.c: Same. * iconvdata/ibm935.c: Same. * iconvdata/ibm937.c: Same. * iconvdata/ibm939.c: Same.

* Set index_Fast_Unaligned_Load for Excavator family CPUsAmit Pawar2016-01-142-0/+14
| | | | | | | | | | | | | GLIBC benchtest testcases shows SSE2_Unaligned based implementations are performing faster compare to SSE2 based implementations for routines: strcmp, strcat, strncat, stpcpy, stpncpy, strcpy, strncpy and strstr. Flag index_Fast_Unaligned_Load is set for Excavator family 0x15h CPU's. This makes SSE2_Unaligned based implementations as default for these routines. [BZ #19467] * sysdeps/x86/cpu-features.c (init_cpu_features): Set index_Fast_Unaligned_Load flag for Excavator family CPUs.
* Add __private_ss to s390 struct tcbhead.Marcin Kościelnicki2016-01-142-0/+8
| | | | | | | | | | Preparation for gcc -fsplit-stack support (gcc bug #68191). The new field is basically identical to the one on x86. Its TCB offset needs to be constant, as it'll be hardcoded in gcc. ChangeLog: * sysdeps/s390/nptl/tls.h (struct tcbhead_t): Add __private_ss field.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds some new header definitions from Linux 4.4: * MCL_ONFAULT is added to bits/mman.h / bits/mman-linux.h (this was already done for hppa). * PTRACE_SECCOMP_GET_FILTER is added to sys/ptrace.h. Along with it, the older PTRACE_GETSIGMASK and PTRACE_SETSIGMASK, added in Linux 3.11 but missed at the time, are also added. Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch). * bits/mman-linux.h [!MCL_CURRENT] (MCL_ONFAULT): New macro. * sysdeps/unix/sysv/linux/alpha/bits/mman.h (MCL_ONFAULT): Likewise. * sysdeps/unix/sysv/linux/powerpc/bits/mman.h (MCL_ONFAULT): Likewise. * sysdeps/unix/sysv/linux/sparc/bits/mman.h (MCL_ONFAULT): Likewise. * sysdeps/unix/sysv/linux/sys/ptrace.h (PTRACE_GETSIGMASK): New enum constant and macro.

* Fix isinf/isnan declaration conflict with C++11Adhemerval Zanella2016-01-112-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | GLIBC declares isinf and isnan as expected by Unix98 and for C99 programs these functions are hidden by the generics inf and isnan macros. However C++11 defines isinf and isnan with the same semantics as C99 but requires that they are functions not macros (C++11 26.8 [c.math] paragraph 10). This then results in a conflict for perfectly valid C++11 programs: -- using std::isinf; using std::isnan; double d1 = isinf(1.0); double d2 = isnan(1.0); d.cc:3:12: error: ‘constexpr bool std::isinf(double)’ conflicts with a previous declaration using std::isinf; [...] /usr/include/bits/mathcalls.h:201:1: note: previous declaration ‘int isinf(double)’ __MATHDECL_1 (int,isinf,, (_Mdouble_ __value)) __attribute__ ((__const__)); [...] -- This patch fixes the prototypes by leaving the obsolete functions defined for C++98 code (since they do not conflict with any standard function in C++98), however preventing them on C++11. No issues found in libstdc++ tests and check on x86_64 and i686 with glibc testsuite. Patch from Jonathan Wakely <jwakely.gcc@gmail.com>. [BZ #19439] * math/bits/mathcalls.h [!__cplusplus || __cplusplus < 201103L] (isinf): Do not declare prototype. [!__cplusplus || __cplusplus < 201103L] (isnan): Likewise.
* Force rereading TZDEFRULES after it was used to set DST rules only (bug #19253)Andreas Schwab2016-01-115-2/+76
| | | | | | | If the TZDEFRULES file was used to set the DST rules when $TZ didn't provide any we need to make sure that the next time it is used we recompute everything as __tzfile_default changes some setting from what is provided by TZDEFRULES.
* Fix doc quoting problems with Texinfo 5Paul Eggert2016-01-102-0/+23
| | | | | | | | | | | | | | | Without this change, in the info file output, Texinfo 5 quotes code in text with undirected single quotes 'like this' and generates code examples that with many PDF readers cannot be cut out of PDFs and pasted into code. * manual/libc.texinfo: Configure the libc manual like the GNU Emacs manual, by using @documentencoding and setting txicodequoteundirected and txicodequotebacktick. This way, Texinfo 5 quotes code in text with directed single quotes ‘like this’ and produces examples that can be cut out of PDFs. This change causes Texinfo 5 to generate info files that contain UTF-8 characters in the set {'‘', '’', '“', '”', 'Ä', 'ä', 'ö', '−', '–', '—', '©', '⇒', '•', '…'}, which is OK nowadays.

* hppa: fix dladdr [BZ #19415]John David Anglin2016-01-083-17/+55
| | | | | | | | | | | | | | | The attached patch fixes dladdr on hppa. Instead of using the generic version of _dl_lookup_address, we use an implementation more or less modeled after __canonicalize_funcptr_for_compare() in gcc. The function pointer is analyzed and if it points to the trampoline used to call _dl_runtime_resolve just before the global offset table, then we call _dl_fixup to resolve the function pointer. Then, we return the instruction pointer from the first word of the descriptor. The change fixes the testcase provided in [BZ #19415] and the Debian nss package now builds successfully.

* xstat: only check to see if __ASSUME_ST_INO_64_BIT is definedMike Frysinger2016-01-075-5/+13
| | | | | | | | We define __ASSUME_ST_INO_64_BIT by default for Linux targets, and then undef it for alpha/sh targets. But the code that uses it looks at its value (as 0/1) rather than whether it's defined (like all other assume knobs). Change the code to see if it's defined to fix build Wundef build errors for alpha/sh.

* hppa: Add MAP_HUGETLB and MAP_STACK defines [BZ #19285]Helge Deller2016-01-022-13/+16
| | | | | | | | | The attached patch adds some upstream defines like MAP_HUGETLB and MAP_STACK in mman.h for the hppa architecture. The existing MADV_xxK_PAGES defines were dropped upstream, because they were originally added many years ago based on a proposed patch for the Linux kernel which was never applied. So, this patch drops those unneeded defines.

* Fix linux personality syscall wrapperDmitry V. Levin2015-12-3116-3/+139
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The personality system call, starting with linux kernel commit v2.6.29-6609-g11d06b2a1e5658f448a308aa3beb97bacd64a940, always successfully changes the personality if requested. The syscall wrapper, however, still can return an error in the following cases: - the value returned by the system call looks like an error due to architecture limitations of 32-bit kernels; - a personality greater than 0xffffffff is passed to the system call, and the 64-bit kernel does not have commit v2.6.35-rc1-372-g485d527686850d68a0e9006dd9904f19f122485e that would truncate this value to unsigned int; - on sparc64, the value returned by the system call looks like an error due to sparc64 kernel sign extension bug. The solution is three-fold: - move generic syscalls.list personality entry to generic 64-bit syscalls.list file; - for each 32-bit architecture that use negated errno semantics, add a NOERRNO personality entry to their syscalls.list file; - for sparc64 and 32-bit architectures that use dedicated registers to flag syscall errors, add a wrapper around personality syscall; if the system call return value is flagged as an error, this wrapper returns the negated "would be errno" value, otherwise it returns the system call return value; on sparc64, it also truncates the personality argument to unsigned int before passing it to the kernel.

* malloc: Test various special cases related to allocation failuresFlorian Weimer2015-12-293-1/+452
| | | | | | | | | | | | | | | | This test case exercises unusual code paths in allocation functions, related to allocation failures. Specifically, the test can reveal the following bugs: (a) calloc returns non-zero memory on fallback to sysmalloc. (b) calloc can self-deadlock because it fails to release the arena lock on certain allocation failures. (c) pvalloc can dereference a NULL arena pointer. (a) and (b) appear specific to a faulty downstream backport. (c) was fixed as part of commit 10ad46bc6526edc5c7afcc57112da96917ff3629. The test for (a) was inspired by a reproducer supplied by Jeff Layton.
* localedata: bg_BG: use colon as time separator [BZ #19385]Damyan Ivanov2015-12-292-2/+8
| | | | | | | | | | | | | The only official source is the "Official spelling dictionary of the Bulgarian language, Prosveta 2012", which states there are three ways to separate time components: comma, colon and dot. That same dictionary doesn't say which one is preferred. So I turned to the mailing list of the translators of free software in Bulgarian. The consensus is that colon is the only separator that is widely used in Bulgarian texts and everything else will just be confusing.

* Do not violate mutex destruction requirements.Torvald Riegel2015-12-235-13/+44
| | | | | | | | | | | | | | | | | | POSIX and C++11 require that a thread can destroy a mutex if no other thread owns the mutex, is blocked on the mutex, or will try to acquire it in the future. After destroying the mutex, it can reuse or unmap the underlying memory. Thus, we must not access a mutex' memory after releasing it. Currently, we can load the private flag after releasing the mutex, which is fixed by this patch. See https://sourceware.org/bugzilla/show_bug.cgi?id=13690 for more background. We need to call futex_wake on the lock after releasing it, however. This is by design, and can lead to spurious wake-ups on unrelated futex words (e.g., when the mutex memory is reused for another mutex). This behavior is documented in the glibc-internal futex API and in recent drafts of the Linux kernel's futex documentation (see the draft_futex branch of git://git.kernel.org/pub/scm/docs/man-pages/man-pages.git).

* powerpc: Export __parse_hwcap_and_convert_at_platform to libc.a.Carlos Eduardo Seo2015-12-222-0/+13
| | | | | | | | | Commit 67385a01d229751569b6aac067ffdcd813a15d7a added a new feature for powerpc, where we store HWCAP/Platform bits in the TCB. In the dynamic linking case, we use the versioned symbol '__parse_hwcap_and_convert_at_platform' to verify if this feature is available. However, the same symbol was not exported to libc.a, making it not possible for GCC to check for it prior to link time.
