* powerpc: Fix compiler warning on some syscallsAdhemerval Zanella2015-01-085-8/+18
| | | | | | | | | | | | | | | | | GCC 5.0 emits an warning when using sizeof on array function parameters and powerpc internal syscall macros add a check for such cases. More specifically, on powerpc64 and powerpc32 sysdep.h: if (__builtin_classify_type (__arg3) != 5 && sizeof (__arg3) > 8) \ __illegally_sized_syscall_arg3 (); \ And for sysdeps/unix/sysv/linux/utimensat.c build GCC emits: error: ‘sizeof’ on array function parameter ‘tsp’ will return size of ‘const struct timespec *’ This patch uses the address of first struct member instead of the struct itself in syscall macro.

* posix/regcomp: initialize union structure tag to avoid warningChris Metcalf2015-01-072-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | We see some surprising warnings on tilegx with gcc 4.8.2: In file included from regex.c:66:0: regcomp.c: In function ‘parse_expression’: regcomp.c:2849:15: error: ‘end_elem’ may be used uninitialized in this function [-Werror=maybe-uninitialized] else if (br_elem->type == COLL_SYM) ^ regcomp.c:3109:34: note: ‘end_elem’ was declared here bracket_elem_t start_elem, end_elem; ^ regcomp.c:3109:22: error: ‘start_elem’ may be used uninitialized in this function [-Werror=maybe-uninitialized] bracket_elem_t start_elem, end_elem; ^ These warnings are not seen on x86, and in fact if I compile the preprocessed tile sources with the x86 gcc 4.8.2, I don't see the warnings. I do see eqiuvalent warnings if I compile the x86-preprocessed source code with tilegx gcc 4.8.2. The fix here is to initialize the union type field appropriately in a couple of places where we pass a union pointer to a subroutine that "knows" what type the union is. Setting the type explicitly seems like a more robust way to manage such a data structure in any case.

* 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.

* 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.

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.

* Fix wordsize-64 posix_fadvise64, posix_fallocate64 namespace (bug 17777).Joseph Myers2015-01-055-9/+18
| | | | | | | | | | | | | | | | | | | | | | | | 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). [BZ #17777] * sysdeps/unix/sysv/linux/wordsize-64/posix_fadvise.c (posix_fadvise64): Define as weak alias not strong alias. * sysdeps/unix/sysv/linux/wordsize-64/posix_fallocate.c (posix_fallocate64): Likewise. * conform/Makefile (test-xfail-XOPEN2K/fcntl.h/linknamespace): Remove variable.

Also tested for ARM (soft-float) that fegetround failures disappear from the linknamespace test failures (feholdexcept, fesetenv, fesetround and feupdateenv remain to be addressed before bug 17748 is fully fixed, although this patch may suffice to fix the failures in some cases, when the libc_fe* functions are implemented but there is no architecture-specific sqrt implementation in use so there were failures from fegetround used by sqrt but no other such failures).

* Fix MIPS TIOCSER_TEMT namespace (bug 17782).Joseph Myers2015-01-023-2/+8
| | | | | | | | | | | | sysdeps/unix/sysv/linux/mips/bits/termios.h defines TIOCSER_TEMT unconditionally, but it's in the user's namespace. This patch conditions it on __USE_MISC, as on powerpc. I've filed bug 17783 for the residual inconsistency in conditions on this macro (sparc defines it for __USE_GNU only). [BZ #17782] * sysdeps/unix/sysv/linux/mips/bits/termios.h (TIOCSER_TEMT): Condition macro definition on [__USE_MISC].

| | | | | | | | | | | sysdeps/unix/sysv/linux/mips/bits/sigaction.h gives sa_flags type unsigned int, but POSIX says it should be signed int. This patch gives it the correct type (the layout is unchanged, so there are no ABI issues involved). [BZ #17781] * sysdeps/unix/sysv/linux/mips/bits/sigaction.h (struct sigaction): Change type of sa_flags field to int.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some C90 libm functions call fegetenv via libc_feholdsetround* functions in math_private.h.
