2013-12-01locale: don't crash if locale-archive contains all zeroslocale-SIGFPEAurelien Jarno
In case of power failure followed by filesystem issues locale-archive can end-up containing all zeros. In that case all calls to setlocale() generate a SIGFPE. This renders a system with a default non-C locale unbootable. Avoid this by ignoring the locale instead of generating a SIGFPE.

2013-11-28Get canonical name in getaddrinfo from hosts file for AF_INET (fixes 16077)Siddhesh Poyarekar
AF_INET lookup in hosts file uses _nss_files_gethostbyname2_r, which is not capable of returning a canonical name if it has found one. This change adds _nss_files_gethostbyname3_r, which wraps around _nss_files_gethostbyname2_r and then returns result.h_name as the canonical name.

2013-11-27MIPS: Fix RLIM64_INFINITY constant for O32 and N32 ABIsAurelien Jarno
Fix the RLIM64_INFINITY constant for O32 and N32 ABIs to match the kernel one. Change the getrlimit64/setrlimit64 into old compat symbols, and provide the Linux generic getrlimit64/setrlimit64 functions as GLIBC_2_19 version.
2013-11-27MIPS: Add wrappers to get/setrlimit64 to fix RLIM64_INFINITY constantAurelien Jarno
RLIM64_INFINITY was supposed to be a glibc convention rather than anything seen by the kernel, but it ended being passed to the kernel through the prlimit64 syscall. On O32 and N32 ABIs, we therefore end-up with different values on the userland and kernel side: * On the kernel side, the value is defined for all architectures as include/uapi/linux/resource.h: #define RLIM64_INFINITY (~0ULL) * On the GNU libc side, the value is defined in ports/sysdeps/unix/sysv/linux/mips/bits/resource.h: For the O32 and N32 ABI: # define RLIM64_INFINITY 0x7fffffffffffffffULL and for the N64 ABI: # define RLIM64_INFINITY 0xffffffffffffffffUL This was not a problem until the prlimit64 syscall was wired in the 2.6.36 kernel. Given the GLIBC uses the prlimit64 syscall to implement getrlimit64 and setrlimit64, pam_limits.so is setting the limits to a very big value instead of infinity. As a normal user process can later only decrease the value and not increase it, it will later get and EPERM error when trying to set the value to infinity with setrlimit. The GLIBC has this constant for more than 7 years, and as it is defined in a header file, it means a lot of binaries are in the wild. This patch fixes that by adding a wrapper to fix the value passed to or received from the kernel, before or after calling the prlimit64 syscall.

The event code is PTRACE_EVENT_SECCOMP, not PTRAVE_EVENT_SECCOMP. This patch fixes the V->C typo. There are no ABI issues since the number remains the same for the code. Code using the old wrong name will need to be updated.

2013-11-25PowerPC: Set/restore rounding mode only when neededAdhemerval Zanella
This patch helps some math functions performance by adding the libc_fexxx variant of inline functions to handle both FPU round and exception set/restore and by using them on the libc_fexxx_ctx functions. It is based on already coded fexxx family functions for PPC with fpu.

2013-11-21Use __glibc_block in public headers.Meador Inge
As detailed in PR11157, the use of '__block' is known to interfere with keywords in some environments, such as the Clang -fblocks extension. Recently a similar issue was raised concerning the use of '__unused' and a '__glibc' prefix was proposed to create a glibc implementation namespace for these sorts of issues [1]. This patches takes that approach. [1] https://sourceware.org/ml/libc-alpha/2012-02/msg00047.html [2] http://lists.debian.org/debian-glibc/2013/11/msg00020.html
2013-11-21Don't use broken DL_AUTO_FUNCTION_ADDRESS()Guy Martin
On hppa and ia64, the macro DL_AUTO_FUNCTION_ADDRESS() uses the variable fptr[2] in it's own scope. The content of fptr[] is thus undefined right after the macro exits. Newer gcc's (>= 4.7) reuse the stack space of this variable triggering a segmentation fault in dl-init.c:69. To fix this we rewrite the macros to make the call directly to init and fini without needing to pass back a constructed function pointer.

2013-11-20linux-generic: fix alignment of struct stat/statfs for nios2Chung-Lin Tang
The hard alignment of 8 was appropriate for most platforms for which 8-byte values are 8-byte aligned, but this is not true for the nios2 platform, so only align to the alignment of the 8-byte type on the platform. Remove the explicit alignment of struct statfs as it's redundant.
