* ia64: setjmp/longjmp: stop saving/restoring fpsr [BZ #16379]Mike Frysinger2013-12-303-10/+10
| | | | | | | | | The new tst-setjmp-fp test has been failing on IA64 because the setjmp and longjmp helpers take care of saving/restoring the fpsr register. Per the C standards, this is incorrect, so disable that logic. URL: https://sourceware.org/bugzilla/show_bug.cgi?id=16379 Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* MIPS: Fix RLIM64_INFINITY constant for O32 and N32 ABIsAurelien Jarno2013-11-277-30/+60
| | | | | | | 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.
* MIPS: Add wrappers to get/setrlimit64 to fix RLIM64_INFINITY constantAurelien Jarno2013-11-272-0/+119
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Don't use broken DL_AUTO_FUNCTION_ADDRESS()Guy Martin2013-11-214-48/+64
| | | | | | | | | | | | 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.
* linux-generic: fix alignment of struct stat/statfs for nios2Chung-Lin Tang2013-11-202-6/+6
| | | | | | | | | 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.

* PowerPC floating point little-endian [1 of 15]Alan Modra2013-10-041-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | http://sourceware.org/ml/libc-alpha/2013-08/msg00081.html This is the first of a series of patches to ban ieee854_long_double and the ieee854_long_double macros when using IBM long double. union ieee854_long_double just isn't correct for IBM long double, especially when little-endian, and pretending it is OK has allowed a number of bugs to remain undetected in sysdeps/ieee754/ldbl-128ibm/. This changes the few places in generic code that use it. * stdio-common/printf_size.c (__printf_size): Don't use union ieee854_long_double in fpnum union. * stdio-common/printf_fphex.c (__printf_fphex): Likewise.

* ARM: Add pointer encryption support.Will Newton2013-10-036-6/+94
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* BZ #15754: CVE-2013-4788Carlos O'Donell2013-09-232-0/+9
| | | | | | | | | | | | 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.
