2015-01-09MicroBlaze: Fix BZ17791 - Remove fixed page size macros and othersMatthew Fortune
Microblaze apparently has a variable page size (see thread below) and should not hard-code any page-size related macros. Also remove macros that are only used for BFD's trad-core support which is not relavant for microblaze also according to the thread starting here: https://sourceware.org/ml/libc-ports/2013-11/msg00028.html This patch is neither built nor tested but mirrors a MIPS patch that fixes the same issue.

2015-01-08powerpc: Fix compiler warning on some syscallsAdhemerval Zanella
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.

2015-01-07posix/regcomp: initialize union structure tag to avoid warningChris Metcalf
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.

2015-01-07setenv fix memory leak when setting large, duplicate string (BZ #17658)Eric Biggers
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)
2015-01-06Fix incorrect mount table entry parsing in __getmntent_rVladimir A. Nazarenko
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.
2015-01-07Fix libm fesetround namespace (bug 17748).Joseph Myers
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. An existing __fesetround function in fenv_libc.h for powerpc is renamed to __fesetround_inline. Tested for x86_64 (testsuite, and that disassembly of installed shared libraries is unchanged by the patch). Also tested for ARM (soft-float) that fesetround failures disappear from the linknamespace test results (feupdateenv remains to be addressed to complete fixing bug 17748).

2015-01-06resolv: fix rotate optionAurelien Jarno
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.

2015-01-05Fix MIPS n64 posix_fadvise namespace (bug 17796).Joseph Myers
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.

* sysdeps/mips/dl-machine.h (elf_machine_load_address): Replace bltzal with addiupc. (RTLD_START): Ditto.
2015-01-05tile: check error properly for vDSO callsChris Metcalf
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.
2015-01-05lround: provide cast for wordsize-64 version if neededChris Metcalf
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.
2015-01-05Fix ARM posix_fadvise64 namespace (bug 17793).Joseph Myers
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.
