* PowerPC: use _dl_static_init to set GLRO(gl_pagesize)Adhemerval Zanella2013-07-235-0/+137
| | | | | | 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.

| | | | * tst-cancel4.c (WRITE_BUFFER_SIZE): Increase to 16384.
* tile BZ #15759: Fix bug in _dl_unmapChris Metcalf2013-07-223-4/+17
| | | | | | We returned without calling __munmap if not in the simulator. Now we call a separate sim_dlclose() function to make the control flow work correctly.

* CVE-2013-2207, BZ #15755: Disable pt_chown.Carlos O'Donell2013-07-2111-7/+100
| | | | | | | | | | | | | | | | | | | | | | | 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.
* Update Sparc ULPs.David S. Miller2013-07-202-0/+10

* BZ #15711: Avoid circular dependency for syscall.hCarlos O'Donell2013-07-163-3/+17
| | | | | | | | | | | | | | | | | | 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.

| | | | | | * math/libm-test.inc (casin_test_data): Annotate more cases of missing underflows from atanl/atan2l due to bug 15319. (casinh_test_data): Likewise.

* tile: use _dl_static_init to set GLRO(gl_pagesize)Chris Metcalf2013-07-075-0/+134
| | | | | | A recently-added test (dlfcn/tststatic5) pointed out that tile was not properly initializing the variable pagesize in certain cases. This change just copies the existing code from MIPS.

* tile: use soft-fp for fma() and fmaf()Chris Metcalf2013-07-074-8/+105
| | | | | | The sfp-machine.h is based on the gcc version, but extended with required new macros by comparison with other architectures and by investigating the hardware support for FP on tile.

* Add lock elision to NEWS fileAndi Kleen2013-07-021-0/+6
|
* Add a configure option to enable lock elision and disable by defaultAndi Kleen2013-07-028-0/+50
| | | | Can be enabled with --enable-lock-elision=yes at configure time.
* Disable elision for any pthread_mutexattr_settype callAndi Kleen2013-07-022-0/+10
| | | | | | | | | | PTHREAD_MUTEX_NORMAL requires deadlock for nesting, DEFAULT does not. Since glibc uses the same value (0) disable elision for any call to pthread_mutexattr_settype() with a 0 value. This implies that a program can disable elision by doing pthread_mutexattr_settype(&attr, PTHREAD_MUTEX_NORMAL) Based on a original proposal by Rich Felker.
* Add elision to pthread_mutex_{try,timed,un}lockAndi Kleen2013-07-0214-24/+267
| | | | | | | | | | | | | | | | | | | | | | | Add elision paths to the basic mutex locks. The normal path has a check for RTM and upgrades the lock to RTM when available. Trylocks cannot automatically upgrade, so they check for elision every time. We use a 4 byte value in the mutex to store the lock elision adaptation state. This is separate from the adaptive spin state and uses a separate field. Condition variables currently do not support elision. Recursive mutexes and condition variables may be supported at some point, but are not in the current implementation. Also "trylock" will not automatically enable elision unless some other lock call has been already called on the lock. This version does not use IFUNC, so it means every lock has one additional check for elision. Benchmarking showed the overhead to be negligible.
* Add minimal test suite changes for elision enabled kernelsAndi Kleen2013-07-023-1/+28
| | | | | | tst-mutex5 and 8 test some behaviour not required by POSIX, that elision changes. This changes these tests to not check this when elision is enabled at configure time.
* Add new internal mutex type flags for elision.Andi Kleen2013-07-023-9/+43
| | | | | | | | | | Add Enable/disable flags used internally Extend the mutex initializers to have the fields needed for elision. The layout stays the same, and this is not visible to programs. These changes are not exposed outside pthread
