* setenv fix memory leak when setting large, duplicate string (BZ #17658)Eric Biggers2015-01-073-4/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | glibc maintains a binary tree of environment strings it malloc()ed itself. However, it's possible for it to malloc() a string, then find that an identical string is already in the tree. In this case, the memory is leaked and is not freed if the application later calls __libc_freeres(). Fix this by freeing 'new_value' when it's unneeded. Test case: #include <stdlib.h> #include <string.h> int main() { char *p = calloc(100000, 1); memset(p, 'A', 99999); setenv("TESTVAR", p, 1); setenv("TESTVAR", p, 1); free(p); } Leak that was reported by valgrind: 100,008 bytes in 1 blocks are definitely lost in loss record 1 of 1 at 0x4C29F90: malloc (in /usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so) by 0x4E6B3D4: __add_to_environ (setenv.c:176) by 0x4C31B8F: setenv (in /usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so) by 0x400642: main (in /mnt/tmpfs/a.out)
* Fix incorrect mount table entry parsing in __getmntent_rVladimir A. Nazarenko2015-01-064-9/+41
| | | | | | | | | When mount entry contains only four fields and have more then one space or tab at the and, mp.mnt_freq and mp.mnt_passno will be set to some specific values as side effect from parsing of previus mount entry. It is because sscanf(""," %d %d ", &a, &b) returns -1, but this case is unprocessed. Values of mp.mnt_freq and mp.mnt_passno stays unchanged. This patch is attempt to fix described issue by removing trailing tabs and spaces.
* Fix libm fesetround namespace (bug 17748).Joseph Myers2015-01-0722-39/+112
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Continuing the fixes for C90 libm functions calling C99 fe* functions, this patch fixes the case of fesetround by making it a weak alias of __fesetround and making the affected code call __fesetround.

* resolv: fix rotate optionAurelien Jarno2015-01-062-1/+7
| | | | | | | | | | | | | | | | | | The rotate option doesn't work correctly, and only send the query to the same server (the second in the list). The rotation code in itself is not broken, but the nsaddrs structure is reinitialized each time at the beginning of __libc_res_nsend unless RES_STAYOPEN is enabled. This is due to a call to __res_iclose from the end of __libc_res_nsend when answers from the name server have been received. This function closes all the sockets, but doesn't free the addresses (it can do that, but in that case the second argument is false). This patch change the code of __res_iclose to clear statp->_u._ext.nsinit only when the addresses are actually freed. * resolv/res_init.c (__res_iclose): Only clear nsinit if the addresses have been freed.

| | | | | | | | | | | | | | | | sysdeps/unix/sysv/linux/mips/mips64/n64/posix_fadvise.c defines posix_fadvise64 as a strong alias for posix_fadvise (for !SHLIB_COMPAT(libc, GLIBC_2_2, GLIBC_2_3_3) - i.e., for static linking, which is the case when this matters), but it should be a weak alias. This patch makes it a weak alias. Tested for MIPS that this fixes the observed linknamespace test failures. [BZ #17796] * sysdeps/unix/sysv/linux/mips/mips64/n64/posix_fadvise.c [!SHLIB_COMPAT(libc, GLIBC_2_2, GLIBC_2_3_3)] (posix_fadvise64): Define as weak alias not strong alias.

* tile: check error properly for vDSO callsChris Metcalf2015-01-054-6/+27
| | | | | | | | The tile vDSO vsyscalls were not properly setting the error value. Conventionally, tile returns the same "non-negative success, negative errno" value that x86 does (in r0), but it also returns "zero or positive errno" in r1, which is what the regular syscall code checks. This change uses that convention for the vDSO calls as well.
* lround: provide cast for wordsize-64 version if neededChris Metcalf2015-01-054-6/+39
| | | | | | | | | Platforms with 64-bit registers where 32-bit values need to have the high 32 bits set in a particular way need to have an explicit cast when using the 64-bit sysdeps/ieee754/dbl-64/wordsize-64 version of llround() as lround(). This includes tilegx32, and likely MIPS. x32 does not need this, and AArch64 ILP32 will not either. Require it to be specified in sysdep.h to be explicit.
* Fix ARM posix_fadvise64 namespace (bug 17793).Joseph Myers2015-01-053-2/+6
| | | | | | | | | | | | | | ARM posix_fadvise calls __posix_fadvise64_l64, to which posix_fadvise64 is a strong alias, but posix_fadvise is a POSIX function and posix_fadvise64 isn't. This patch changes it into a weak alias. Tested for ARM that this fixes the corresponding linknamespace test failures. [BZ #17793] * sysdeps/unix/sysv/linux/arm/posix_fadvise64.c (posix_fadvise64): Define as weak alias not strong alias.
* Fix isblank / isascii / toascii namespace (bug 17635).Joseph Myers2015-01-057-26/+73
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use of isblank brings in isascii and toascii, but isblank is a C99 function and the other two aren't; similarly, isascii and toascii are UNIX98 functions and bring in isblank, which isn't. (Not a conformance issue because of the is* and to* reservation, but still contrary to glibc practice.) This patch fixes this by splitting isblank out of ctype-extn.c to a separate ctype-c99.c. isblank_l is also moved to a separate file, ctype-c99_l.c (non-XSI POSIX.1-2008 has isblank_l, but isascii / toascii are marked OB XSI). (In principle all these functions could go in separate files - that's optimal for static linking - but they are also all very small, and splitting them all out is not needed to fix the present bug.) Tested for x86_64 (testsuite, and that installed stripped shared libraries are unchanged by the patch - the ordering in which new and existing sources are listed in ctype/Makefile is arranged so functions go in the same order so that this comparison works). [BZ #17635] * ctype/ctype-c99.c: New file. isblank implementation moved from ... * ctype/ctype-extn.c: ... here. (__isblank_l): Move to ... * ctype/ctype-c99_l.c: ... here.

| | | | | | | | | | | | | | | | | | | | | | | | On systems using sysdeps/unix/sysv/linux/wordsize-64, posix_fadvise64 and posix_fallocate64 (non-POSIX) are strong aliases for posix_fadvise and posix_fallocate (POSIX), meaning references to the latter wrongly bring in definitions of the former. They should be weak aliases; this patch makes them so. Tested for x86_64 (testsuite, and that disassembly of installed shared libraries is unchanged by the patch).

* powerpc: POWER7 strcpy optimization for unaligned stringsRajalakshmi Srinivasaraghavan2014-12-313-82/+268
| | | | | | | | | | | | | | | | This patch optimizes strcpy for ppc64/power7 for unaligned source or destination address. The source or destination address is aligned to doubleword and data is shifted based on the alignment and added with the previous loaded data to be written as a doubleword. For each load, cmpb instruction is used for faster null check. The word aligned optimization is also removed, since the new unaligned code path shows better results handling word-aligned strings. More combination of unaligned inputs is also added in benchtest to measure the improvement.The new optimization shows 2 to 80% of performance improvement for longer string though it does not show big difference on string size less than 16 due to additional checks.
* Clean up powerpc fegetround / __fegetround inlines.Joseph Myers2014-12-3110-56/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The natural fix for some linknamespace test failures, where C90 libm functions call C99 <fenv.h> functions, is to make fe* into weak aliases for __fe* and call __fe* from within libm as needed. To do this, the __fe* names need to be available for that purpose - that is, they must not be used for something other than aliases of fe*. On powerpc, however, __fegetround is an inline function in fenv_libc.h, with no corresponding fegetround inline function; fegetround has an equivalent macro expansion in bits/fenvinline.h, but that is disabled if __NO_MATH_INLINES (which is defined for building libm). I see no need for that disabling; it's not even clear that __NO_MATH_INLINES should affect <fenv.h>, and the results of fegetround are completely defined so there is no semantic effect of that disabling at all outside glibc. The x86 inline feraiseexcept is conditioned on __USE_EXTERN_INLINES not __NO_MATH_INLINES (but that's an inline function rather than a macro). This patch removes the __NO_MATH_INLINES conditional on that fegetround macro, so resulting in it being expanded inline inside glibc. In turn, this means that direct calls to __fegetround from C99 functions in ldbl-128ibm can be changed to calls to fegetround, so that nofpu fenv_libc.h files don't need to define __fegetround at all and, by changing ldbl-128ibm files to use <fenv.h> not <fenv_libc.h>, non-e500 nofpu no longer needs an fenv_libc.h file. The other macros in fenvinline.h are left conditional on __NO_MATH_INLINES, although since the only case where this should make a difference is one involving undefined behavior (if the argument to the function is not a valid exception macro). The out-of-line definition for fegetround uses __fegetround (the inline function removed by this patch). So this continues to work, the fenvinline.h header is made to define __fegetround, and then to define fegetround to call __fegetround. Tested for powerpc32 (hard float) that installed stripped shared libraries are unchanged by this patch; also tested that powerpc-nofpu build still works. (This patch does not itself fix any bugs; it simply cleans things up in preparation for separate bug fixes.) * sysdeps/powerpc/bits/fenvinline.h (fegetround): Rename macro to __fegetround and redefine to call __fegetround.

* Fix libm feraiseexcept namespace (bug 17723).Joseph Myers2014-12-3044-71/+211

This causes linknamespace test failures - except on x86 / x86_64, where feraiseexcept is inline (for the relevant constant arguments) in bits/fenv.h. This patch fixes this by making those functions call __feraiseexcept instead. All changes are applied to all architectures rather than considering the possibility that some might not be needed in some cases (e.g. x86) as it seems most maintainable to keep architectures consistent. Where __feraiseexcept does not exist, it is added, with feraiseexcept made a weak alias; where it is a strong alias, it is made weak. libm_hidden_def / libm_hidden_proto are used with __feraiseexcept (this might in some cases improve code generation for existing calls to __feraiseexcept in some code on some architectures). Where there are dummy feraiseexcept macros (on architectures without floating-point exceptions support, to avoid compile errors from references to undefined FE_* macros), corresponding dummy __feraiseexcept macros are added. And on x86, to ensure __feraiseexcept calls still get inlined, the inline function in bits/fenv.h is refactored so that most of it can be reused in an inline __feraiseexcept in a separate include/bits/fenv.h. Calls are changed in C90/UNIX98 functions, but generally not in functions missing from those standards. They are also changed in libc_fe* functions (on the basis that those might be used in any libm function), and in feupdateenv (on the same basis - may be used, via default libc_*, in any libm function - of course feupdateenv will need changing to __feupdateenv in a subsequent patch to make that fully namespace-clean). No __feraiseexcept is added corresponding to the feraiseexcept in powerpc bits/fenvinline.h, because that macro definition is conditional on !defined __NO_MATH_INLINES, and glibc libm is built with -D__NO_MATH_INLINES, so changing internal calls to use __feraiseexcept should make no difference. Tested for x86_64 (testsuite; the only change in disassembly of installed shared libraries is a slight code reordering in clog10, of no apparent significance). Also tested for MIPS, where (in the configuration tested) it eliminates math.h linknamespace failures for n32 and n64 (some for o32 remain because of other issues).
