* ARM: Fix clone build for ARMv4Will Newton2014-01-242-7/+7
| | | | | | | | | | | | | | | ARMv4 does not have the blx instruction, so use the BLX macro which handles abstracting this for us. Build tested for armv7, armv4t and armv4. ports/ChangeLog.arm: 2014-01-24 Will Newton <will.newton@linaro.org> [BZ #16499] * sysdeps/unix/sysv/linux/arm/clone.S: Use BLX macro instead of blx instruction directly.
* Adjust pointers to triplets in netgroup query data (BZ #16474)Siddhesh Poyarekar2014-01-243-2/+18
| | | | | | | | | The _nss_*_getnetgrent_r query populates the netgroup results in the allocated buffer and then sets the result triplet to point to strings in the buffer. This is a problem when the buffer is reallocated since the pointers to the triplet strings are no longer valid. The pointers need to be adjusted so that they now point to strings in the reallocated buffer.

* S/390: Increase tst-tls7 test case timeoutStefan Liebler2014-01-232-1/+5

* PowerPC: Fix gettimeofday ifunc selectionAdhemerval Zanella2014-01-204-5/+18
| | | | | | | | | | | | The IFUNC selector for gettimeofday runs before _libc_vdso_platform_setup where __vdso_gettimeofday is set. The selector then sets __gettimeofday (the internal version used within GLIBC) to use the system call version instead of the vDSO one. This patch changes the check if vDSO is available to get its value directly instead of rely on __vdso_gettimeofday. This patch changes it by getting the vDSO value directly. It fixes BZ#16431.

* Don't check asynchronous cancellation on systemH.J. Lu2014-01-182-1/+5
| | | | | | | | | | | | | | | | | | | | Since asynchronous cancellation was removed from system by commit c4dd57c300aa05ab2f957d571c321237a58d0368 Author: Ondřej Bílka <neleai@seznam.cz> Date: Tue Jan 14 16:07:50 2014 +0100 Do not enable asynchronous cancellation in system. Fixes bug 14782. We needlessly enabled thread cancellation before it was necessary. As only call that needs to be guarded is waitpid which is cancellation point we could remove cancellation altogether. we shouldn't check asynchronous cancellation on system.

* s390: implement sotruss supportMike Frysinger2014-01-162-0/+66
| | | | | | | | | | | | | See commit 41b1792698a335d3a85381921a84a16e9635f36a for testcase. Note: while this works on s390x, the s390 code hangs when using -e. But it hangs regardless of this code (the hang seems to occur before the exit func is even called). I didn't look too closely at it as it seems to be an issue external to this file, so this code shouldn't make the situation any worse.

* PowerPC: Fix ftime gettimeofday internal call returning bogus dataAdhemerval Zanella2014-01-163-4/+44
| | | | | | | | | | | | This patches fixes BZ#16430 by setting a different symbol for internal GLIBC calls that points to ifunc resolvers. For PPC32, if the symbol is defined as hidden (which is the case for gettimeofday and time) the compiler will create local branches (symbol@local) and linker will not create PLT calls (required for IFUNC). This will leads to internal symbol calling the IFUNC resolver instead of the resolved symbol. For PPC64 this behavior does not occur because a call to a function in another translation unit might use a different toc pointer thus requiring a PLT call.
* Fix math/test-fpucw-*.c for sysdeps test-fpucw.c overrides.Joseph Myers2014-01-163-2/+7
| | | | | | | | | | | | | | | | | | | | | | | ARM has an override of the test math/test-fpucw.c, to disable (for soft-float testing) definitions of hard-float macros in fpu_control.h that the header normally defines not only when building for hard-float, but also when building for soft-float with _LIBC defined so that libc code can dynamically test whether VFP hardware is present. (_LIBC is defined when building tests, although ideally it wouldn't be.) The override doesn't work for the derived tests test-fpucw-*.c because they use #include "" instead of <> to include test-fpucw.c, so always get the math/ version instead of the ARM sysdeps override. This patch changes them to use <> so the sysdeps override is effective. (test-fpucw-ieee-static.c doesn't need a change because it includes test-fpucw-ieee.c, which isn't itself being overridden, which in turn includes test-fpucw.c with a #include changed by this patch.) Tested for ARM (big-endian soft-float, non-VFP hardware). * math/test-fpucw-ieee.c: Use <> in #include of test-fpucw.c. * math/test-fpucw-static.c: Likewise.

* Don't use alloca in addgetnetgrentX (BZ #16453)Siddhesh Poyarekar2014-01-163-32/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | addgetnetgrentX has a buffer which is grown as per the needs of the requested size either by using alloca or by falling back to malloc if the size is larger than 1K. There are two problems with the alloca bits: firstly, it doesn't really extend the buffer since it does not use the return value of the extend_alloca macro, which is the location of the reallocated buffer. Due to this the buffer does not actually extend itself and hence a subsequent write may overwrite stuff on the stack. The second problem is more subtle - the buffer growth on the stack is discontinuous due to block scope local variables. Combine that with the fact that unlike realloc, extend_alloca does not copy over old content and you have a situation where the buffer just has garbage in the space where it should have had data. This could have been fixed by adding code to copy over old data whenever we call extend_alloca, but it seems unnecessarily complicated. This code is not exactly a performance hotspot (it's called when there is a cache miss, so factors like network lookup or file reads will dominate over memory allocation/reallocation), so this premature optimization is unnecessary. Thanks Brad Hubbard <bhubbard@redhat.com> for his help with debugging the problem.

* ARM: Don't apply pointer encryption to the frame pointerWill Newton2014-01-145-11/+20
| | | | | | | | | | | | | | | | | | | | | The frame pointer register is rarely used for that purpose on ARM and applications that look at the contents of the jmp_buf may be relying on reading an unencrypted value. For example, Ruby uses the contents of jmp_buf to find the root set for garbage collection so relies on this pointer value being unencrypted. Without this patch the Ruby testsuite fails with a segmentation fault. ports/ChangeLog.arm: 2013-01-14 Will Newton <will.newton@linaro.org> * sysdeps/arm/__longjmp.S: Don't apply pointer encryption to fp register. * sysdeps/arm/setjmp.S: Likewise. * sysdeps/arm/include/bits/setjmp.h (JMP_BUF_REGLIST): Add fp to register list, remove a4. * sysdeps/unix/sysv/linux/arm/sysdep.h (PTR_MANGLE_LOAD): New macro.

* Rename header.pot to pot.header.Carlos O'Donell2014-01-083-4/+9
| | | | | | | | | | | The Translation Project has asked us to rename the pot header file `header.pot' to something else. Their scripts automatically look for pot files and the file `header.pot' is not actually a pot file but a header that we use when regenerating `libc.pot.' This commit renames `header.pot' to `pot.header' to avoid causing errors or complicating the TP project scripts.

* PowerPC: remove wrong truncl implementation for PowerPC64Adhemerval Zanella2014-01-084-125/+9
| | | | | | | | | | | | | | | The truncl assembly implementation (sysdeps/powerpc/powerpc64/fpu/s_truncl.S) returns wrong results for some inputs where first double is a exact integer and the precision is determined by second long double. Checking on implementation comments and history, I am very confident the assembly implementation was based on a version before commit 5c68d401698a58cf7da150d9cce769fa6679ba5f that fixes BZ#2423 (Errors in long double (ldbl-128ibm) rounding functions in glibc-2.4). By just removing the implementation and make the build select sysdeps/ieee754/ldbl-128ibm/s_truncl.c instead it fixes tgammal issues regarding wrong result sign.

* Fix ldbl-128ibm expm1l on large arguments (bug 16408).Joseph Myers2014-01-083-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes bug 16408, ldbl-128ibm expm1l returning NaN for some large arguments. The basic problem is that the approach of converting the exponent to the form n * log(2) + y, where -0.5 <= y <= 0.5, then computing 2^n * expm1(y) + (2^n - 1) falls over when 2^n overflows (starting slightly before the point where expm1 overflows, when y is negative and n is the least integer for which 2^n overflows). The ldbl-128 code, and the x86/x86_64 code, make expm1l fall back to expl for large positive arguments to avoid this issue. This patch makes the ldbl-128ibm code do the same. (The problem appears for the particular argument in the testsuite because the ldbl-128ibm code also uses an overflow threshold that's for ldbl-128 and is too big for ldbl-128ibm, but the problem described applies for large non-overflowing cases as well, although during the freeze is not a suitable time for making the expm1 tests cover cases close to overflow more thoroughly.) This leaves some code for large positive arguments in expm1l that is now dead. To keep the code for ldbl-128 and ldbl-128ibm similar, and to avoid unnecessary changes during the freeze, the patch doesn't remove it; instead I propose to file a bug in Bugzilla as a reminder that this code (for overflow, including errno setting, and for arguments of +Inf) is no longer needed and should be removed from both those expm1l implementations. Tested powerpc32. * sysdeps/ieee754/ldbl-128ibm/s_expm1l.c (__expm1l): Use __expl for large positive arguments.
* Use separate libc.abilist for MIPS o32 soft float.Joseph Myers2014-01-073-0/+2268
| | | | | | | | | | | | | | | | | | | | Examining MIPS test results showed an ABI test failure that I must have missed in 2.18 testing: hard-float and soft-float o32 no longer have the same set of symbols (because of the __mips_fpu_getcw and __mips_fpu_setcw functions, present for hard-float only, used by fpu_control.h for hard-float MIPS16) and so need separate ABI test baselines (they always were ABI-incompatible - the function-calling interface is different - but previously had the same set of symbols and versions so didn't need separate baselines). Tested for hard-float and soft-float o32. * sysdeps/unix/sysv/linux/mips/mips32/nptl/libc.abilist: Move to .... * sysdeps/unix/sysv/linux/mips/mips32/fpu/nptl/libc.abilist: ... here. * sysdeps/unix/sysv/linux/mips/mips32/nofpu/nptl/libc.abilist: New file.
