* PowerPC: Fix __fe_mask_env exportAdhemerval Zanella2013-11-132-2/+2
| | | | Change SHLIB_COMPAT calls to GLIBC_2_19 for __fe_nomask_env symbol.
* Set arch_minimum_kernel to 3.4.0 for x32H.J. Lu2013-11-132-0/+6
| | | | x32 ABI support was added in Linux kernel 3.4.0.
* PowerPC: Fix __fe_mask_env exportAdhemerval Zanella2013-11-133-6/+10
| | | | | This patch does not export __fe_mask_env anymore, only providing a compatibility symbol. It fixes BZ#14143.
* PowerPC: Fix vDSO missing ODP entriesAdhemerval Zanella2013-11-083-5/+28
| | | | | | | This patch fixes the vDSO symbol used directed in IFUNC resolver where they do not have an associated ODP entry leading to undefined behavior in some cases. It adds an artificial OPD static entry to such cases and set its TOC to non 0 to avoid triggering lazy resolutions.
* Restrict shm_open and shm_unlink to SHMDIR. Fixes bugs 14752 and 15763.Ondřej Bílka2013-10-311-6/+8

* rename configure.in to configure.acMike Frysinger2013-10-304-2/+2
| | | | | | | Autoconf has been deprecating configure.in for quite a long time. Rename all our configure.in and preconfigure.in files to .ac. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* PowerPC SIGSTKSZAlan Modra2013-10-041-0/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | http://sourceware.org/ml/libc-alpha/2013-08/msg00093.html This copies the sparc version of sigstack.h, which gives powerpc #define MINSIGSTKSZ 4096 #define SIGSTKSZ 16384 Before the VSX changes, struct rt_sigframe size was 1920 plus 128 for __SIGNAL_FRAMESIZE giving ppc64 exactly the default MINSIGSTKSZ of 2048. After VSX, ucontext increased by 256 bytes. Oops, we're over MINSIGSTKSZ, so powerpc has been using the wrong value for quite a while. Add another ucontext for TM and rt_sigframe is now at 3872, giving actual MINSIGSTKSZ of 4000. The glibc testcase that I was looking at was tst-cancel21, which allocates 2*SIGSTKSZ (not because the test is trying to be conservative, but because the test actually has nested signal stack frames). We blew the allocation by 48 bytes when using current mainline gcc to compile glibc (le ppc64). The required stack depth in _dl_lookup_symbol_x from the top of the next signal frame was 10944 bytes. I guess you'd want to add 288 to that, implying an actual SIGSTKSZ of 11232. * sysdeps/unix/sysv/linux/powerpc/bits/sigstack.h: New file.
* PowerPC makecontextAlan Modra2013-10-042-4/+10
| | | | | | | | | | | http://sourceware.org/ml/libc-alpha/2013-08/msg00092.html Use conditional form of branch and link to avoid destroying the cpu link stack used to predict blr return addresses. * sysdeps/unix/sysv/linux/powerpc/powerpc32/makecontext.S: Use conditional form of branch and link when obtaining pc. * sysdeps/unix/sysv/linux/powerpc/powerpc64/makecontext.S: Likewise.
* PowerPC LE _dl_hwcap accessAlan Modra2013-10-043-16/+16
| | | | | | | | | | | http://sourceware.org/ml/libc-alpha/2013-08/msg00091.html More LE support, correcting word accesses to _dl_hwcap. * sysdeps/unix/sysv/linux/powerpc/powerpc32/getcontext-common.S: Use HIWORD/LOWORD. * sysdeps/unix/sysv/linux/powerpc/powerpc32/setcontext-common.S: Ditto. * sysdeps/unix/sysv/linux/powerpc/powerpc32/swapcontext-common.S: Ditto.
* tst-fanotify: fix styleMike Frysinger2013-09-281-8/+9

* Add O_TMPFILE to <fcntl.h>Andreas Schwab2013-09-112-0/+5

* Coordinate IPv6 definitions for Linux and glibcCarlos O'Donell2013-09-061-0/+12
| | | | | | | | | | This change synchronizes the glibc headers with the Linux kernel headers and arranges to coordinate the definition of structures already defined the Linux kernel UAPI headers. It is now safe to include glibc's netinet/in.h or Linux's linux/in6.h in any order in a userspace application and you will get the same ABI. The ABI is guaranteed by UAPI and glibc.
* tst-fanotify: skip when we get back EPERMMike Frysinger2013-09-051-5/+8
| | | | | | | | Since fanotify_init requires CAP_SYS_ADMIN in order to work (which usually means running as root), we need to handle that error case too. Reported-by: Andreas Jaeger <aj@suse.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* tst-fanotify: new simple testMike Frysinger2013-09-022-1/+57
| | | | | | Basic test for the fanotify functions. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* PowerPC: fix backtrace to handle signal trampolinesAdhemerval Zanella2013-08-202-0/+23
| | | | | | This patch fixes backtrace for PPC32 and PPC64 to correctly handle signal trampolines. The 'debug/tst-backtrace6.c' also check for SA_SIGINFO handling, where is triggers another vDSO symbols for PPC32.

Return delayed error code. Remove GETDENTS_64BIT_ALIGNED conditional. * sysdeps/unix/sysv/linux/wordsize-64/readdir_r.c: Do not define GETDENTS_64BIT_ALIGNED. * sysdeps/unix/sysv/linux/i386/readdir64_r.c: Likewise. * manual/filesys.texi (Reading/Closing Directory): Document ENAMETOOLONG return value of readdir_r. Recommend readdir more strongly. * manual/conf.texi (Limits for Files): Add portability note to NAME_MAX, PATH_MAX. (Pathconf): Add portability note for _PC_NAME_MAX, _PC_PATH_MAX.
* PowerPC: use _dl_static_init to set GLRO(gl_pagesize)Adhemerval Zanella2013-07-234-0/+129
| | | | | | This patch fixes dlfcn/tststatic5 for PowerPC where pagesize variable was not properly initialized in certain cases. This patch is based on other architecture code.
* CVE-2013-2207, BZ #15755: Disable pt_chown.Carlos O'Donell2013-07-211-2/+3
| | | | | | | | | | | | | | | | | | | | | | | The helper binary pt_chown tricked into granting access to another user's pseudo-terminal. Pre-conditions for the attack: * Attacker with local user account * Kernel with FUSE support * "user_allow_other" in /etc/fuse.conf * Victim with allocated slave in /dev/pts Using the setuid installed pt_chown and a weak check on whether a file descriptor is a tty, an attacker could fake a pty check using FUSE and trick pt_chown to grant ownership of a pty descriptor that the current user does not own. It cannot access /dev/pts/ptmx however. In most modern distributions pt_chown is not needed because devpts is enabled by default. The fix for this CVE is to disable building and using pt_chown by default. We still provide a configure option to enable hte use of pt_chown but distributions do so at their own risk.
* BZ #15711: Avoid circular dependency for syscall.hCarlos O'Donell2013-07-161-2/+9
| | | | | | | | | | | | | | | | | | The generated header is compiled with `-ffreestanding' to avoid any circular dependencies against the installed implementation headers. Such a dependency would require the implementation header to be installed before the generated header could be built (See bug 15711). In current practice the generated header dependencies do not include any of the implementation headers removed by the use of `-ffreestanding'. --- 2013-07-15 Carlos O'Donell <carlos@redhat.com> [BZ #15711] * sysdeps/unix/sysv/linux/Makefile ($(objpfx)bits/syscall%h): Avoid system header dependency with -ffreestanding. ($(objpfx)bits/syscall%d): Likewise.

* New API to set default thread attributesSiddhesh Poyarekar2013-06-1510-0/+40
| | | | | | | This patch introduces two new convenience functions to set the default thread attributes used for creating threads. This allows a programmer to set the default thread attributes just once in a process and then run pthread_create without additional attributes.
* Improve precision of clock() function on LinuxSiddhesh Poyarekar2013-06-131-20/+16
| | | | | | | Resolves #12515. Use CLOCK_PROCESS_CPUTIME_ID instead of times to get better precision in the value returned by clock.
* Fix symbol definitions for __clock_* functionsSiddhesh Poyarekar2013-06-112-5/+5
| | | | | | __clock_gettime and other __clock_* functions could result in an extra PLT reference within libc.so if it actually gets used. None of the code currently uses them, which is why this probably went unnoticed.
