2016-05-18Update libm-test.inc comment about NaN signs.Joseph Myers
libm-test.inc has a comment about signs of NaNs not being tested. This is out of date since: commit ce66581742e7ae1d6ce59e5d2d4859b2ae41218c Author: Joseph Myers <joseph@codesourcery.com> Date: Sat Nov 16 12:48:35 2013 +0000 Test signs of NaNs in libm-test.inc where appropriate.

Clear the destination buffer updated by the previous run in bench-memcpy.c and test-memcpy.c to catch the error when the following implementations do not copy anything. [BZ #19907] * benchtests/bench-memcpy.c (do_one_test): Clear the destination buffer updated by the previous run. * string/test-memcpy.c (do_one_test): Likewise. * benchtests/bench-memmove.c (do_one_test): Add a comment. * string/test-memmove.c (do_one_test): Likewise.
2016-05-17Do not declare grantpt, ptsname, unlockpt in stdlib.h for XPG3 (bug 20094).Joseph Myers
stdlib.h declares grantpt, ptsname, unlockpt for __USE_XOPEN. This patch corrects the condition to __USE_XOPEN_EXTENDED (these functions are new in XPG4). Tested for x86_64 and x86 (testsuite, and that installed shared libraries are unchanged by the patch). [BZ #20094] * stdlib/stdlib.h (grantpt): Declare if [__USE_XOPEN_EXTENDED], not [__USE_XOPEN]. (unlockpt): Likewise. (ptsname): Likewise. * conform/Makefile (test-xfail-XPG3/stdlib.h/conform): Remove variable.
2016-05-17Make sys/stat.h define S_IFSOCK, S_ISSOCK for XPG4 (bug 20076).Joseph Myers
sys/stat.h should define S_IFSOCK and S_ISSOCK for XPG4 (XNS), but does not. This patch corrects the relevant header conditionals. Tested for x86_64 and x86 (testsuite, and that installed shared libraries are unchanged by the patch). [BZ #20076] * io/sys/stat.h (S_IFSOCK): Define for [__USE_XOPEN_EXTENDED] instead of [__USE_UNIX98]. (S_ISSOCK): Likewise. * conform/Makefile (test-xfail-XPG4/sys/stat.h/conform): Remove variable.
2016-05-17Fix stdlib.h rand_r namespace (bug 20074).Joseph Myers
stdlib.h declares rand_r if __USE_POSIX; i.e., POSIX.1:1990. But rand_r was added along with threads, so the condition should be __USE_POSIX199506. This patch corrects the condition. Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch). [BZ #20074] * stdlib/stdlib.h (rand_r): Declare if [__USE_POSIX199506], not if [__USE_POSIX]. * conform/Makefile (test-xfail-XPG4/stdlib.h/conform): Remove variable.
2016-05-17Correct ttyslot header declaration conditions (bug 20051).Joseph Myers
UNIX98 and XPG4 have ttyslot in <stdlib.h>. glibc, however, has it in <unistd.h>, for __USE_MISC || (__USE_XOPEN_EXTENDED && !__USE_UNIX98), but no supported standard has it in <unistd.h>. This patch adds a properly conditioned declaration to <stdlib.h> (only enabled for the relevant standards, not for __USE_MISC or __USE_GNU). The <unistd.h> declaration is restricted to __USE_MISC. Some relevant XFAILs are removed. Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch). [BZ #20051] * posix/unistd.h [__USE_XOPEN_EXTENDED && !__USE_UNIX98] (ttyslot): Do not declare. * stdlib/stdlib.h [__USE_XOPEN_EXTENDED && !__USE_XOPEN2K] (ttyslot): New prototype. * conform/Makefile (test-xfail-XPG4/unistd.h/conform): Remove variable. (test-xfail-UNIX98/stdlib.h/conform): Likewise.
2016-05-17Fix tst-cancel17/tst-cancelx17, which sometimes segfaults while exiting.Stefan Liebler
The testcase tst-cancel[x]17 ends sometimes with a segmentation fault. This happens in one of 10000 cases. Then the real testcase has already exited with success and returned from do_test(). The segmentation fault occurs after returning from main in _dl_fini(). In those cases, the aio_read(&a) was not canceled because the read request was already in progress. In the meanwhile aio_write(ap) wrote something to the pipe and the read request is able to read the requested byte. The read request hasn't finished before returning from do_test(). After it finishes, it writes the return value and error code from the read syscall to the struct aiocb a, which lies on the stack of do_test. The stack of the subsequent function call of _dl_fini or _dl_sort_fini, which is inlined in _dl_fini is corrupted. In case of S390, it reads a zero and decrements it by 1: unsigned int k = nmaps - 1; struct link_map **runp = maps[k]->l_initfini; The load from unmapped memory leads to the segmentation fault. The stack corruption also happens on other architectures. I saw them e.g. on x86 and ppc, too. This patch adds an aio_suspend call to ensure, that the read request is finished before returning from do_test(). ChangeLog: * nptl/tst-cancel17.c (do_test): Wait for finishing aio_read(&a).
2016-05-13tst-mallocfork2: Fix race condition, use fewer resourcesFlorian Weimer
The first SIGUSR1 signal could arrive when sigusr1_sender_pid was still 0. As a result, kill would send SIGSTOP to the entire process group. This would cause the test to hang before printing any output. This commit also adds a sched_yield to the signal source, so that it does not flood the parent process with signals it has never a chance to handle. Even with these changes, tst-mallocfork2 still fails reliably after the fix in commit commit 56290d6e762c1194547e73ff0b948cd79d3a1e03 (Increase fork signal safety for single-threaded processes) is backed out.
2016-05-13conformtest: Correct some stdlib.h expectations for XPG3.Joseph Myers
This patch corrects some spurious conformtest stdlib.h expectations for XPG3 (not based on a full review of the expectations for that standard, so other issues may remain). Tested for x86_64 and x86. * conform/data/stdlib.h-data (a64l): Do not expect for [XPG3]. (ecvt): Likewise. (fcvt): Likewise. (gcvt): Likewise. (getsubopt): Likewise. (grantpt): Likewise.

2016-05-13conformtest: Do not expect strdup in string.h for XPG3.Joseph Myers
This patch corrects a spurious conformtest expectation of strdup in string.h for XPG3. Tested for x86_64 and x86. * conform/data/string.h-data (strdup): Do not expect for [XPG3]. * conform/Makefile (test-xfail-XPG3/string.h/conform): Remove variable.
2016-05-13Call init_cpu_features only if SHARED is definedH.J. Lu
In static executable, since init_cpu_features is called early from __libc_start_main, there is no need to call it again in dl_platform_init. [BZ #20072] * sysdeps/i386/dl-machine.h (dl_platform_init): Call init_cpu_features only if SHARED is defined. * sysdeps/x86_64/dl-machine.h (dl_platform_init): Likewise.

* sysdeps/x86/cacheinfo.c (init_cacheinfo): Check and support non-inclusive caches on Intel processors.
2016-05-13malloc: Rewrite dumped heap for compatibility in __malloc_set_stateFlorian Weimer
This will allow us to change many aspects of the malloc implementation while preserving compatibility with existing Emacs binaries. As a result, existing Emacs binaries will have a larger RSS, and Emacs needs a few more milliseconds to start. This overhead is specific to Emacs (and will go away once Emacs switches to its internal malloc). The new checks to make free and realloc compatible with the dumped heap are confined to the mmap paths, which are already quite slow due to the munmap overhead. This commit weakens some security checks, but only for heap pointers in the dumped main arena. By default, this area is empty, so those checks are as effective as before.
2016-05-12conformtest: Correct time.h XPG3 expectations.Joseph Myers
This patch corrects spurious conformtest expectations of getdate and getdate_err for XPG3. (This is not based on a full review of the expectations, so there may be other issues where the header and tests agree but are both incorrect.) Tested for x86_64 and x86. * conform/data/time.h-data (getdate_err): Do not expect for [XPG3]. (getdate): Likewise. * conform/Makefile (test-xfail-XPG3/time.h/conform): Remove variable.
2016-05-12conformtest: Correct some unistd.h expectations for XPG3, XPG4.Joseph Myers
The conformtest tests of unistd.h fail for XPG3 because of various expectations that are incorrect for XPG3. This patch corrects those bogus expectations, and one bogus expectation for XPG4. (This is not based on a full review of the standards so there may well still be other bugs in the expectations for this header.) Tested for x86_64 and x86. * conform/data/unistd.h-data (F_LOCK): Do not expect for [XPG3]. (F_ULOCK): Likewise. (F_TEST): Likewise. (F_TLOCK): Likewise. (useconds_t): Likewise.

2016-05-12Declare gethostname for XPG4 (bug 20054).Joseph Myers
unistd.h declares gethostname for __USE_UNIX98 || __USE_XOPEN2K. But it's also in XPG4 (XNS volume - C438 - not the main definitions of system interfaces and headers in C435). This patch corrects the condition. Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch). [BZ #20054] * posix/unistd.h (gethostname): Declare if [__USE_XOPEN_EXTENDED], not [__USE_UNIX98]. * conform/data/unistd.h-data (gethostname): Do not expect for [XPG3].
2016-05-12conformtest: Do not expect S_IF* in fcntl.h.Joseph Myers
The conform/ tests for fcntl.h are failing for XPG3 and XPG4 because of missing S_IFSOCK. This is a case of a bogus test. The relevant wording requiring such constants is, in current POSIX (and this requirement dates back as far as XPG4), "The <fcntl.h> header shall define the symbolic constants for file modes for use as values of mode_t as described in <sys/stat.h>.". Note that this is *file modes* not *file types*. That makes sense, since the point is presumably for use with functions such as open that are declared in fcntl.h, where file modes are relevant but file types aren't. So this patch removes all those spurious S_IF* expectations for fcntl.h (the macros are generally still *allowed* through the permission to make everything from sys/stat.h visible). Tested for x86_64 and x86. * conform/data/fcntl.h-data [!POSIX] (S_IFMT): Do not expect. [!POSIX] (S_IFBLK): Likewise. [!POSIX] (S_IFCHR): Likewise. [!POSIX] (S_IFIFO): Likewise. [!POSIX] (S_IFREG): Likewise. [!POSIX] (S_IFDIR): Likewise. [!POSIX] (S_IFLNK): Likewise. [!POSIX] (S_IFSOCK): Likewise. * conform/Makefile (test-xfail-XPG3/fcntl.h/conform): Remove variable.

2016-05-12This is an optimized memset for AArch64. Memset is split into 4 main cases:Wilco Dijkstra
small sets of up to 16 bytes, medium of 16..96 bytes which are fully unrolled. Large memsets of more than 96 bytes align the destination and use an unrolled loop processing 64 bytes per iteration. Memsets of zero of more than 256 use the dc zva instruction, and there are faster versions for the common ZVA sizes 64 or 128. STP of Q registers is used to reduce codesize without loss of performance. The speedup on test-memset is 1% on Cortex-A57 and 8% on Cortex-A53. * sysdeps/aarch64/memset.S (__memset): Rewrite of optimized memset.
2016-05-12Increase fork signal safety for single-threaded processes [BZ #19703]Florian Weimer
This provides a band-aid and addresses the scenario where fork is called from a signal handler while the process is in the malloc subsystem (or has acquired the libio list lock). It does not address the general issue of async-signal-safety of fork; multi-threaded processes are not covered, and some glibc subsystems have fork handlers which are not async-signal-safe.
2016-05-12getaddrinfo: Convert from extend_alloca to struct scratch_bufferFlorian Weimer
2016-05-11Declare tcgetsid for XPG4 (bug 20055).Joseph Myers
termios.h should declare tcgetsid for XPG4, but only does so for __USE_UNIX98 || __USE_XOPEN2K8 at present. This patch fixes the declaration conditions. A spurious conformtest expectation of this declaration for XPG3 is removed, and two XFAILs that are fixed by these changes are also removed. Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch). [BZ #20055] * termios/termios.h (pid_t): Define for [__USE_XOPEN_EXTENDED] instead of [__USE_UNIX98]. (tcgetsid): Declare for [__USE_XOPEN_EXTENDED] instead of [__USE_UNIX98]. * conform/data/termios.h-data (tcgetsid): Do not expect for [XPG3]. * conform/Makefile (test-xfail-XPG3/termios.h/conform): Remove variable.

__malloc_initialize_hook is deprecated.
2016-05-11S390: Use fPIC to avoid R_390_GOT12 relocation in gcrt1.o.Stefan Liebler
if glibc is build with -march=z900 | -march=z990, the startup file gcrt1.o (used if you link with gcc -pg) contains R_390_GOT12 | R_390_GOT20 relocations. Thus, an entry in the GOT can be addressed relative to the GOT pointer with a 12 | 20 bit displacement value. The startup files should not contain R_390_GOT12, R_390_GOT20 relocations, but R_390_GOTENT ones. This patch removes the overrides of pic-ccflag and the default pic-ccflag = -fPIC in Makeconfig is used instead to get the R_390_GOTENT relocations in gcrt1.o. ChangeLog: * sysdeps/s390/s390-32/Makefile (pic-ccflag): Remove. * sysdeps/s390/s390-64/Makefile: Likewise.

Merge x86 ifunc-defines.sym with x86 cpu-features-offsets.sym. Remove x86 ifunc-defines.sym and rtld-global-offsets.sym. No code changes on i686 and x86-64. * sysdeps/i386/i686/multiarch/Makefile (gen-as-const-headers): Remove ifunc-defines.sym. * sysdeps/x86_64/multiarch/Makefile (gen-as-const-headers): Likewise. * sysdeps/i386/i686/multiarch/ifunc-defines.sym: Removed. * sysdeps/x86/rtld-global-offsets.sym: Likewise. * sysdeps/x86_64/multiarch/ifunc-defines.sym: Likewise. * sysdeps/x86/Makefile (gen-as-const-headers): Remove rtld-global-offsets.sym. * sysdeps/x86_64/multiarch/ifunc-defines.sym: Merged with ... * sysdeps/x86/cpu-features-offsets.sym: This. * sysdeps/x86/cpu-features.h: Include <cpu-features-offsets.h> instead of <ifunc-defines.h> and <rtld-global-offsets.h>.
2016-05-10Fix sys/stat.h fchmod namespace (bug 20073).Joseph Myers
sys/stat.h declares fchmod if __USE_POSIX (i.e. POSIX.1:1990). But it was actually added in 1993 and also in XPG4. This patch changes the conditions to the correct __USE_POSIX199309 || __USE_XOPEN_EXTENDED. Tested for x86_64 and x86 (testsuite, and that installed shared libraries are unchanged by the patch). [BZ #20073] * io/sys/stat.h (fchmod): Declare for [__USE_POSIX199309 || __USE_XOPEN_EXTENDED], not [__USE_POSIX]. * conform/Makefile (test-xfail-XPG3/sys/stat.h/conform): Remove variable.
2016-05-10conformtest: Correct some sys/stat.h expectations for XPG3.Joseph Myers
This patch fixes various conformtest sys/stat.h expectations that were incorrect for XPG3 (not based on a full review, so not necessarily an exhaustive set of such corrections). Most of these corrections fix spurious failures shown in testing (but that for fchmod introduces a correct failure, as that function is wrongly declared for XPG3, so this doesn't eliminate any XFAILs). Tested for x86_64 and x86. * conform/data/sys/stat.h-data [XPG3] (S_IFLNK): Do not expect. [XPG3] (S_IFSOCK): Likewise. [XPG3] (S_ISVTX): Likewise. [XPG3] (S_ISLNK): Likewise.

2016-05-10conformtest: Fix st_blksize, st_blocks expectations for XPG3, XPG4.Joseph Myers
The conformtest expectations expect the struct stat fields st_blksize and st_blocks to be of types blksize_t and blkcnt_t. But XPG4 does not have those types, using long instead, and XPG3 does not have these fields at all. This patch adjusts the expectations for those standards, XFAILing them for XPG4 to allow for systems where the typedefs don't correspond to long. Tested for x86_64 and x86. * conform/data/sys/stat.h-data (st_blksize): Do not expect for [XPG3]. Expect type long and XFAIL for [XPG4]. (st_blocks): Likewise.
2016-05-10Declare pthread_atfork in unistd.h for UNIX98 (bug 20044).Joseph Myers
For UNIX98 (only), unistd.h should declare pthread_atfork, but that declaration is missing. This patch adds it. Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch). [BZ #20044] * posix/unistd.h [__USE_UNIX98 && !__USE_XOPEN2K] (pthread_atfork): New prototype. * conform/Makefile (test-xfail-UNIX98/unistd.h/conform): Remove variable.
2016-05-10Declare cuserid in unistd.h for UNIX98 and before (bug 20043).Joseph Myers
For UNIX98 and older X/Open standards, unistd.h should have a declaration of the legacy cuserid function, but such a declaration is missing. This patch adds that missing declaration. Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch). [BZ #20043] * posix/unistd.h [__USE_XOPEN && !__USE_XOPEN2K] (cuserid): New prototype.

2016-05-09conformtest: Remove some bogus sys/types.h expectations for XPG3 and XPG4.Joseph Myers
The conformtest tests for sys/types.h for XPG3 and XPG4 fail because of missing blksize_t. This is a bug in the expectations; that type is not part of those standards. This patch stops the tests from expecting it, and some other types that also are not part of XPG3 and XPG4. Tested for x86_64 and x86. * conform/data/sys/types.h-data (blkcnt_t): Do not expect for [XPG3 || XPG4]. (blksize_t): Likewise.

2016-05-09S390: Add support for vdso getcpu symbol.Stefan Liebler
This patch adds support for symbol __kernel_getcpu in vDSO, which is available with kernel 4.5. Now sched_getcpu is using this symbol if available in mapped vDSO by defining macro HAVE_GETCPU_VSYSCALL. If not available at runtime, the former syscall is used.

2016-05-04getnameinfo: Return EAI_OVERFLOW in more cases [BZ #19787]Florian Weimer
The AF_LOCAL and AF_INET/AF_INET6 non-numerci service conversion did not return EAI_OVERFLOW if the supplied buffer was too small, silently returning truncated data. In the AF_INET/AF_INET6 numeric cases, the snprintf return value checking was incorrect.
2016-05-04getnameinfo: Avoid calling strnlen on uninitialized bufferFlorian Weimer
In the numeric AF_INET/AF_INET6 case, if inet_ntop fails as the result of a short host buffer, we used to call strnlen on the uninitialized host buffer.

2016-05-04powerpc: Fix operand prefixesGabriel F. T. Gomes
The file sysdeps/powerpc/sysdeps.h defines aliases for condition register operands. E.g.: 'cr7' means condition register 7. On the one hand, this increases readability, as it makes it easier for readers to know whether the operand is a condition register, a general purpose register or an immediate. On the other hand, this permits that condition registers be written as if they were general purpose, and vice-versa, thus reducing the readability of the code. This commit removes some of these unintentional misuses. The changes have no effect on the final code. Checked with objdump.
2016-05-04CVE-2016-1234: glob: Do not copy d_name field of struct dirent [BZ #19779]Florian Weimer
Instead, we store the data we need from the return value of readdir in an object of the new type struct readdir_result. This type is independent of the layout of struct dirent.
