2013-12-30ia64: longjmp_chk: support signal stacks [BZ #16372]Mike Frysinger
The sp check has to be moved up to the start of the func since it now makes a system call and that'll clobber a lot of registers. URL: https://sourceware.org/bugzilla/show_bug.cgi?id=16372 Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2013-12-30ia64: setjmp/longjmp: stop saving/restoring fpsr [BZ #16379]Mike Frysinger
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>

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.

2013-11-22ARM: Fix memcpy computed-jump calculations for ARM_ALWAYS_BX case.Roland McGrath
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.

2013-10-04PowerPC floating point little-endian [1 of 15]Alan Modra
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. Use signbit macro to retrieve sign from long double. * stdio-common/printf_fp.c (___printf_fp): Use signbit macro to retrieve sign from long double. * sysdeps/ieee754/ldbl-128ibm/printf_fphex.c: Adjust for fpnum change. * sysdeps/ieee754/ldbl-128/printf_fphex.c: Likewise. * sysdeps/ieee754/ldbl-96/printf_fphex.c: Likewise. * sysdeps/x86_64/fpu/printf_fphex.c: Likewise. * math/test-misc.c (main): Don't use union ieee854_long_double. ports/ * sysdeps/ia64/fpu/printf_fphex.c: Adjust for fpnum change.

2013-10-03ARM: Add pointer encryption support.Will Newton
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. (_JMPBUF_UNWINDS_ADJ): Call _jmpbuf_sp. * sysdeps/arm/setjmp.S (__sigsetjmp): Mangle fp, sp and lr before storing register values. * sysdeps/arm/sysdep.h (LDST_GLOBAL): New macro. * sysdeps/unix/sysv/linux/arm/sysdep.h (PTR_MANGLE): New macro. (PTR_DEMANGLE): Likewise. (PTR_MANGLE2): Likewise. (PTR_DEMANGLE2): Likewise.
