* Fix erroneous (and circular) implied pattern rule for linkobj/libc.so.Brooks Moses2013-10-033-33/+41
| | | | | | | | | | | | | | | | | [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.
* ARM: Add pointer encryption support.Will Newton2013-10-037-6/+109
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for pointer encryption in glibc internal structures in C and assembler code. Pointer encryption is a glibc security feature described here: https://sourceware.org/glibc/wiki/PointerEncryption The ARM implementation uses global variables instead of thread pointer relative accesses to get the value of the pointer encryption guard because accessing the thread pointer can be very expensive on older ARM cores. ports/ChangeLog.arm: 2013-10-03 Will Newton <will.newton@linaro.org> * sysdeps/arm/__longjmp.S (__longjmp): Demangle fp, sp and lr when restoring register values. * sysdeps/arm/include/bits/setjmp.h (JMP_BUF_REGLIST): Remove sp and lr from list and replace fp with a4. * sysdeps/arm/jmpbuf-unwind.h (_jmpbuf_sp): New function.

| | | | | | | | Fixes BZ #15988. The check had a typo - it checked for PTHREAD_MUTEX_ROBUST_NP instead of PTHREAD_MUTEX_ROBUST_NORMAL_NP. It has now been replaced by the already existing convenience macro USE_REQUEUE_PI.

* don't use Bash-specific ${parameter/pattern/string} expansionPatrick 'P. J.' McDermott2013-09-283-3/+11
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* Check for integer overflow in cache size computation in strcollSiddhesh Poyarekar2013-09-235-1/+84
| | | | | | | | | | | 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.
* Fall back to non-cached sequence traversal and comparison on malloc failSiddhesh Poyarekar2013-09-233-35/+254
| | | | | | | | 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.
* BZ #15754: Fix test case for ARM.Carlos O'Donell2013-09-233-1/+14
| | | | | | | 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.
* BZ #15754: CVE-2013-4788Carlos O'Donell2013-09-2319-5/+351
| | | | | | | | | | | | 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.
