* BZ #15754: CVE-2013-4788Carlos O'Donell2013-09-231-0/+16
| | | | | | | | | | | | 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.
* Fix static-binary lazy FPU context allocationMaciej W. Rozycki2013-09-091-4/+1
| | | | | | | | | | | | | | | | | | | Long ago static startup did not parse the auxiliary vector and therefore could not get at any `AT_FPUCW' tag to check whether upon FPU context allocation the kernel would use a FPU control word setting different to that provided by the `__fpu_control' variable. Static startup therefore always initialized the FPU control word, forcing immediate FPU context allocation even for binaries that otherwise never used the FPU. As from GIT commit f8f900ecb9096ec47f5b7bb7626e29223c69061a static startup supports parsing the auxiliary vector, so now it can avoid explicit initialization of the FPU control word, just as can dynamic startup, in the usual case where the setting written to the FPU control word would be the same as the kernel uses. This defers FPU context allocation until the binary itself actually pokes at the FPU. Note that the `AT_FPUCW' tag is usually absent from the auxiliary vector in which case _FPU_DEFAULT is assumed to be the kernel default.

* Declare __ehdr_start with hidden visibility.Maciej W. Rozycki2013-04-251-1/+2
| | | | | | | | This avoids a linker bug triggering for MIPS SVR4 binaries: http://sourceware.org/bugzilla/show_bug.cgi?id=15365 and regardless serves as a documentation of intent.

* Revert GLIBC_PTHREAD_DEFAULT_STACKSIZE changes.Carlos O'Donell2013-03-012-3/+3
| | | | | | | This reverts the change that allows the POSIX Thread default stack size to be changed by the environment variable GLIBC_PTHREAD_DEFAULT_STACKSIZE. It has been requested that more discussion happen before this change goes into 2.18.
