2014-02-05Fix tst-setgetname for Linux kernels < 2.6.33.Carlos O'Donell1-0/+6
Support for /proc/self/task/$tid/comm as added in Linux 2.6.33, therefore since the test tst-setgetname relies on this functionality to operate we must skip the test in kernels < 2.6.33. We wrap the checks with __ASSUME_PROC_PID_TASK_COMM such that in the future when we move arch_minimum_kernel to 2.6.33 we can remove this code.

2014-01-20PowerPC: Fix gettimeofday ifunc selectionAdhemerval Zanella2-4/+10
The IFUNC selector for gettimeofday runs before _libc_vdso_platform_setup where __vdso_gettimeofday is set. The selector then sets __gettimeofday (the internal version used within GLIBC) to use the system call version instead of the vDSO one. This patch changes the check if vDSO is available to get its value directly instead of rely on __vdso_gettimeofday. This patch changes it by getting the vDSO value directly. It fixes BZ#16431.
2014-01-16PowerPC: Fix ftime gettimeofday internal call returning bogus dataAdhemerval Zanella2-4/+36
This patches fixes BZ#16430 by setting a different symbol for internal GLIBC calls that points to ifunc resolvers. For PPC32, if the symbol is defined as hidden (which is the case for gettimeofday and time) the compiler will create local branches (symbol@local) and linker will not create PLT calls (required for IFUNC). This will leads to internal symbol calling the IFUNC resolver instead of the resolved symbol. For PPC64 this behavior does not occur because a call to a function in another translation unit might use a different toc pointer thus requiring a PLT call.

2013-12-22Flatten sysdeps/unix/bsd/bsd4.4 into sysdeps/unix/bsd.Joseph Myers1-1/+1
As discussed in <https://sourceware.org/ml/libc-alpha/2012-04/msg00840.html> and <https://sourceware.org/ml/libc-alpha/2012-04/msg00989.html>, it seems appropriate to flatten sysdeps/unix/bsd/bsd4.4 into sysdeps/unix/bsd. The bulk of the patch is just moving files. The only other changes are: update paths in sysdeps/mach/hurd/Implies and sysdeps/unix/sysv/linux/wait3.c; merge the two syscalls.list files, with the removal of syscalls that were in sysdeps/unix/bsd/syscalls.list but overridden in the bsd4.4 directory by .c files there. Tested x86_64. The installed shared libraries are identical before and after the patch except for libc.so where the move of wait3.c (included by sysdeps/unix/sysv/linux/wait3.c) affects debug info, but the disassembly is unchanged. * sysdeps/mach/hurd/Implies: Change unix/bsd/bsd4.4 to unix/bsd. * sysdeps/unix/bsd/syscalls.list (chflags): Add entry from sysdeps/unix/bsd/bsd4.4/syscalls.list.

2013-12-04PowerPC64 ELFv2 ABI 6/6: Bump ld.so soname version numberUlrich Weigand5-7/+190
To avoid having a ELFv2 binary accidentally picking up an old ABI ld.so, this patch bumps the soname to ld64.so.2. In theory (or for testing purposes) this will also allow co-installing ld.so versions for both ABIs on the same system. Note that the kernel will already be able to load executables of both ABIs. However, there is currently no plan to use that theoretical possibility in a any supported distribution environment ... Note that in order to check which ABI to use, we need to invoke the compiler to check the _CALL_ELF macro; this is done in a new configure check in sysdeps/unix/sysv/linux/powerpc/powerpc64/configure.ac, replacing the hard-coded value of default-abi in the Makefile.
2013-12-04PowerPC64 ELFv2 ABI 4/6: Stack frame layout changesUlrich Weigand5-59/+43
This updates glibc for the changes in the ELFv2 relating to the stack frame layout. These are described in more detail here: http://gcc.gnu.org/ml/gcc-patches/2013-11/msg01149.html http://gcc.gnu.org/ml/gcc-patches/2013-11/msg01146.html Specifically, the "compiler and linker doublewords" were removed, which has the effect that the save slot for the TOC register is now at offset 24 rather than 40 to the stack pointer. In addition, a function may now no longer necessarily assume that its caller has set up a 64-byte register save area its use. To address the first change, the patch goes through all assembler files and replaces immediate offsets in instructions accessing the ABI-defined stack slots by symbolic offsets. Those already were defined in ucontext_i.sym and used in some of the context routines, but that doesn't really seem like the right place for those defines. The patch instead defines those symbolic offsets in sysdeps.h, in two variants for the old and new ABI, and uses them systematically in all assembler files, not just the context routines. The second change only affected a few assembler files that used the save area to temporarily store some registers. In those cases where this happens within a leaf function, this patch changes the code to store those registers to the "red zone" below the stack pointer. Otherwise, the functions already allocate a stack frame, and the patch changes them to add extra space in these frames as temporary space for the ELFv2 ABI.
2013-12-04PowerPC64 ELFv2 ABI 2/6: Remove function descriptorsUlrich Weigand3-1/+12
This patch adds support for the ELFv2 ABI feature to remove function descriptors. See this GCC patch for in-depth discussion: http://gcc.gnu.org/ml/gcc-patches/2013-11/msg01141.html This mostly involves two types of changes: updating assembler source files to the new logic, and updating the dynamic loader. After the refactoring in the previous patch, most of the assembler source changes can be handled simply by providing ELFv2 versions of the macros in sysdep.h. One somewhat non-obvious change is in __GI__setjmp: this used to "fall through" to the immediately following __setjmp ENTRY point. This is no longer safe in the ELFv2 since ENTRY defines both a global and a local entry point, and you cannot simply fall through to a global entry point as it requires r12 to be set up. Also, makecontext needs to be updated to set up registers according to the new ABI for calling into the context's start routine. The dynamic linker changes mostly consist of removing special code to handle function descriptors. We also need to support the new PLT and glink format used by the the ELFv2 linker, see: https://sourceware.org/ml/binutils/2013-10/msg00376.html In addition, the dynamic linker now verifies that the dynamic libraries it loads match its own ABI. The hack in VDSO_IFUNC_RET to "synthesize" a function descriptor for vDSO routines is also no longer necessary for ELFv2.
2013-12-04PowerPC64 ELFv2 ABI 1/6: Code refactoringUlrich Weigand1-3/+1
This is the first patch to support the new ELFv2 ABI in glibc. As preparation, this patch simply refactors some of the powerpc64 assembler code to move all code related to creating function descriptors (.opd section) or using function descriptors (function pointer call) into a central place in sysdep.h. Note that most locations creating .opd entries were already using macros in sysdep.h, this patch simply extends this to the remaining places. No relevant change in generated code expected.
