2013-10-04IBM long double mechanical changes to support little-endianAlan Modra1-0/+16
http://sourceware.org/ml/libc-alpha/2013-07/msg00001.html This patch starts the process of supporting powerpc64 little-endian long double in glibc. IBM long double is an array of two ieee doubles, so making union ibm_extended_long_double reflect this fact is the correct way to access fields of the doubles. * sysdeps/ieee754/ldbl-128ibm/ieee754.h (union ibm_extended_long_double): Define as an array of ieee754_double. (IBM_EXTENDED_LONG_DOUBLE_BIAS): Delete. * sysdeps/ieee754/ldbl-128ibm/printf_fphex.c: Update all references to ibm_extended_long_double and IBM_EXTENDED_LONG_DOUBLE_BIAS. * sysdeps/ieee754/ldbl-128ibm/e_exp10l.c: Likewise. * sysdeps/ieee754/ldbl-128ibm/e_expl.c: Likewise. * sysdeps/ieee754/ldbl-128ibm/ldbl2mpn.c: Likewise. * sysdeps/ieee754/ldbl-128ibm/math_ldbl.h: Likewise. * sysdeps/ieee754/ldbl-128ibm/mpn2ldbl.c: Likewise. * sysdeps/ieee754/ldbl-128ibm/s_nearbyintl.c: Likewise. * sysdeps/ieee754/ldbl-128ibm/strtold_l.c: Likewise. * sysdeps/ieee754/ldbl-128ibm/x2y2m1l.c: Likewise.

2013-10-03Fix erroneous (and circular) implied pattern rule for linkobj/libc.so.Brooks Moses1-0/+6
[BZ #15915] As described in the bug, the pattern rule for lib%.so files in Makerules includes linkobj/libc.so as a dependency. However, the explicit rule for linkobj/libc.so is in the top-level Makefile. Thus, the subdirectory makefiles that include Makerules end up with an erroneous makefile pattern rule for linkobj/libc.so that includes itself as a dependency. The result is make warnings whenever rules for other .so files are resolved -- and, on occasion, actual makefile failures when a race condition causes the implicit rule to actually be used. This patch moves the explicit rules for linkobj/libc.so into Makerules to clear up this problem. It also elaborates a couple of comments that I'd initially found confusing.

2013-09-28don't use Bash-specific ${parameter/pattern/string} expansionPatrick 'P. J.' McDermott1-0/+6
sysdeps/unix/make-syscalls.sh and sysdeps/unix/Makefile use GNU Bash's ${parameter/pattern/string} parameter expansion. Non-Bash shells (e.g. dash or BusyBox ash when built with CONFIG_ASH_BASH_COMPAT disabled) don't support this expansion syntax. So glibc will fail to build when $(SHELL) expands to a path that isn't provided by Bash. An example build failure: for dir in [...]; do \ test -f $dir/syscalls.list && \ { sysdirs='[...]' \ asm_CPP='gcc -c -I[...] -D_LIBC_REENTRANT -include include/libc-symbols.h -DASSEMBLER -g -Wa,--noexecstack -E -x assembler-with-cpp' \ /bin/sh sysdeps/unix/make-syscalls.sh $dir || exit 1; }; \ test $dir = sysdeps/unix && break; \ done > [build-dir]/sysd-syscallsT sysdeps/unix/make-syscalls.sh: line 273: syntax error: bad substitution This patch simply replaces the three instances of the Bash-only syntax in these files with an echo and sed command substitution.

2013-09-23Check for integer overflow in cache size computation in strcollSiddhesh Poyarekar1-0/+6
strcoll is implemented using a cache for indices and weights of collation sequences in the strings so that subsequent passes do not have to search through collation data again. For very large string inputs, the cache size computation could overflow. In such a case, use the fallback function that does not cache indices and weights of collation sequences. Fixes CVE-2012-4412.
2013-09-23Fall back to non-cached sequence traversal and comparison on malloc failSiddhesh Poyarekar1-0/+10
strcoll currently falls back to alloca if malloc fails, resulting in a possible stack overflow. This patch implements sequence traversal and comparison without caching indices and rules. Fixes CVE-2012-4424.
2013-09-23BZ #15754: Fix test case for ARM.Carlos O'Donell1-0/+5
Statically built binaries use __pointer_chk_guard_local, while dynamically built binaries use __pointer_chk_guard. Provide the right definition depending on the test case we are building.
2013-09-23BZ #15754: CVE-2013-4788Carlos O'Donell1-0/+30
The pointer guard used for pointer mangling was not initialized for static applications resulting in the security feature being disabled. The pointer guard is now correctly initialized to a random value for static applications. Existing static applications need to be recompiled to take advantage of the fix. The test tst-ptrguard1-static and tst-ptrguard1 add regression coverage to ensure the pointer guards are sufficiently random and initialized to a default value.
