2014-09-12Remove configuration name patterns from shlib-versions.Joseph Myers
This patch removes the first column (patterns matching configuration names) from shlib-versions, leaving shlib-versions entry selection based purely on sysdeps directories. An implication of this removal is that the default for any non-Linux ports using NPTL will be the same SONAMEs for NPTL libraries as for Linux (as those defaults, previously limited to .*-.*-linux.*, are left in nptl/shlib-versions and nptl_db/shlib-versions). Special host_os handling in configure.ac that was purely for shlib-versions is removed. (The host_os setting is still used for libc-abis - see <https://sourceware.org/ml/libc-alpha/2014-01/msg00375.html> regarding that - but no entries there are affected by this change.) Tested on x86_64 and x86 that the installed shared libraries are unchanged by this patch. * scripts/soversions.awk: Do not handle configuration names. * Makeconfig ($(common-objpfx)soversions.i): Do not pass cpu, vendor and os variables to soversions.awk. * configure.ac: Do not modify gnu-* host_os. * configure: Regenerated * shlib-versions: Remove first column with configuration names. * nptl/shlib-versions: Likewise. * nptl_db/shlib-versions: Likewise. * sysdeps/hppa/shlib-versions: Likewise. * sysdeps/m68k/shlib-versions: Likewise. * sysdeps/mach/hurd/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/aarch64/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/alpha/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/arm/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/hppa/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/ia64/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/m68k/coldfire/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/microblaze/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/mips/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc64/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/s390/s390-64/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/sh/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc32/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc64/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/tile/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/x86_64/64/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/x86_64/x32/shlib-versions: Likewise. libidn/ChangeLog: * shlib-versions: Remove first column with configuration names.
2014-09-12Use %ifdef in sysdeps/unix/sysv/linux/powerpc/powerpc64/shlib-versions.Joseph Myers
This patch makes sysdeps/unix/sysv/linux/powerpc/powerpc64/shlib-versions use %ifdef conditionals around the different symbol version definitions for big and little endian. (It doesn't actually change the host patterns used for those definitions; the point is to make it possible to remove the first column from shlib-versions by eliminating the last case where it would be harmful for it to be treated as .*-.*-.*.) The conditional is based on the ELFv1/ELFv2 distinction rather than BE/LE, since that's what's already tested in configure and used for the ld.so soname in the Makefiles. (Of course if BE ELFv2 were supported in future, it would get new symbol versions and so need new conditionals.) * sysdeps/unix/sysv/linux/powerpc/powerpc64/configure.ac (HAVE_ELFV2_ABI): AC_DEFINE in ELFv2 case. * sysdeps/unix/sysv/linux/powerpc/powerpc64/configure: Regenerated. * config.h.in (HAVE_ELFV2_ABI): New macro undefine. * sysdeps/unix/sysv/linux/powerpc/powerpc64/shlib-versions: Condition symbol version definitions on [HAVE_ELFV2_ABI].
2014-09-12Move OS-specific shlib-versions entries to sysdeps files.Joseph Myers
This patch moves OS-specific entries in the top-level shlib-versions file to appropriate sysdeps directories. I left the entries in nptl/shlib-versions and nptl_db/shlib-versions unchanged; I think it can be for those doing non-Linux NPTL-using ports to figure out whether those entries should actually be OS-independent or should move to sysdeps. Given these two patches, I think the only further change needed before the first column of shlib-versions can be eliminated will be changing sysdeps/unix/sysv/linux/powerpc/powerpc64/shlib-versions to use %ifdef to distinguish BE and LE configurations, instead of relying on the powerpc64-.*-linux.* and powerpc.*le-.*-linux.* patterns. Tested on x86_64 that the installed shared libraries are unchanged by this patch. * shlib-versions: Remove OS-specific entries. Moved to files in sysdeps. * sysdeps/mach/hurd/shlib-versions: New file. * sysdeps/unix/sysv/linux/shlib-versions: Likewise.
2014-09-12Move architecture-specific shlib-versions entries to sysdeps files.Joseph Myers
This patch eliminates another way in which ex-ports and non-ex-ports architectures differ, by moving architecture-specific entries from the top-level shlib-versions file and that in nptl/ to appropriate sysdeps directories. As with my previous patch <https://sourceware.org/ml/libc-alpha/2014-06/msg00949.html>, I do not change the regular expressions used; even where the present expressions seem more general, I believe they are in fact specific to the chosen sysdeps directory, because any port that matches the expression but not the sysdeps directory does not currently exist, and so would use different symbol versions if added in future (and an intended goal of these changes is to eliminate the first column in shlib-versions completely rather than having two different mechanisms in use for system-specific configuration). Tested on x86_64 that this does not change the installed shared libraries. (x86_64 of course does not provide much test coverage for this patch - what should be architecture-specific contents in shlib-versions for x86_64 is currently abi-*-ld-soname Makefile settings, until gnu/lib-names.h is generated more like gnu/stubs.h so those can move back to shlib-versions.) * nptl/shlib-versions: Remove architecture-specific entries. Moved to files in sysdeps. * shlib-versions: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc64/shlib-versions: New file. * sysdeps/unix/sysv/linux/s390/s390-64/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/sh/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc32/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc64/shlib-versions: Likewise.
2014-09-12Add new Linux 3.16 constants to netinet/udp.h.Joseph Myers
This patch adds the new constants UDP_NO_CHECK6_TX and UDP_NO_CHECK6_RX from Linux 3.16 to sysdeps/gnu/netinet/udp.h. (I believe the existing constants there are already Linux-specific, possibly with the intention that other OSes should adopt the same values if possible if adopting the features in question.) Tested on x86_64. * sysdeps/gnu/netinet/udp.h (UDP_NO_CHECK6_TX): New macro. (UDP_NO_CHECK6_RX): Likewise.

2014-09-12Complete the removal of __gconv_translit_findFlorian Weimer
Prior to the 2.20 release, the function was just changed to fail unconditionally, in commit a1a6a401ab0a3c9f15fb7eaebbdcee24192254e8. This commit removes the function completely, including gconv bits which depend on it. This changes the gconv ABI, which is not a public interface.
2014-09-12Enhance tst-xmmymm.sh to detect zmm register usage in ld.so (BZ #16194)Siddhesh Poyarekar
2d63a517e4084ec80403cd9f278690fa8b676cc4 added support to save and restore zmm register in the dynamic linker, but did not enhance test-xmmymm.sh to detect accidental usage of these registers. The patch below adds that check. The script has also been renamed to tst-ld-sse-use.sh. To see the minimal changes, run `git show -M`. [BZ #16194] * sysdeps/x86/tst-xmmymm.sh: Rename file to... * sysdeps/x86/tst-ld-sse-use.sh: ... this. Check for zmm register usage. * sysdeps/x86/Makefile: Adjust.

2014-09-10Return failure in getnetgrent only when all netgroups have been searched ↵Siddhesh Poyarekar
(#17363) The netgroups lookup code fails when one of the groups in the search tree is empty. In such a case it only returns the leaves of the tree after the blank netgroup. This is because the line parser returns a NOTFOUND status when the netgroup exists but is empty. The __getnetgrent_internal implementation needs to be fixed to try remaining groups if the current group is entry. This patch implements this fix. Tested on x86_64. [BZ #17363] * inet/getnetgrent_r.c (__internal_getnetgrent_r): Try next group if the current group is empty.
2014-09-10PowerPC: memset optimization for POWER8/PPC64Adhemerval Zanella
This patch adds an optimized memset implementation for POWER8. For sizes from 0 to 255 bytes, a word/doubleword algorithm similar to POWER7 optimized one is used. For size higher than 255 two strategies are used: 1. If the constant is different than 0, the memory is written with altivec vector instruction; 2. If constant is 0, dbcz instructions are used. The loop is unrolled to clear 512 byte at time. Using vector instructions increases throughput considerable, with a double performance for sizes larger than 1024. The dcbz loops unrolls also shows performance improvement, by doubling throughput for sizes larger than 8192 bytes.
2014-09-10PowerPC: multiarch bzero cleanup for PPC64Adhemerval Zanella
This patch cleanups the multiarch bzero for powerpc64 by remove the multiarch objects and use instead the the memset embedded implementation presented in each multiarch optimization. The code generate is essentially the same, but the TB_TOCLESS (which is not essential).
2014-09-10Turn on -Werror=implicit-function-declarationFlorian Weimer
GCC 4.4, the minimum compiler version, supports this option. Unlike other warnings, -Wimplicit-function-declaration warnings should be independent of compiler versions, so this change should not cause compiler-specific build failures.

2014-09-07HPPA: Transition to new non-addon NPTL.Carlos O'Donell
Merge roland/nptl-hppa to master, update and test for hppa-linux-gnu. This commit squashes and commits the work done by Roland McGrath on roland/nptl-hppa to migrate hppa to the new non-addon NPTL. Some additional tweaks were required for tcb-offsets.sym to work correctly along with clone.S (unique to hppa).

2014-09-06[BZ #17354] tile: Fix up corner cases with signed relocationsChris Metcalf
Some types of relocations technically need to be signed rather than unsigned: in particular ones that are used with moveli or movei, or for jump and branch. This is almost never a problem. Jump and branch opcodes are pretty much uniformly resolved by the static linker (unless you omit -fpic for a shared library, which is not recommended). The moveli and movei opcodes that need to be sign-extended generally are for positive displacements, like the construction of the address of main() from _start(). However, tst-pie1 ends up with main below _start (in a different module) and the test failed due to signedness issues in relocation handling. This commit treats the value as signed when shifting (to preserve the high bit) and also sign-extends the value generated from the updated bundle when comparing with the desired bundle, which we do to make sure no overflow occurred. As a result, the tst-pie1 test now passes.

2014-08-28i386 TLS_INIT_TP might produce bogus asm changing stack pointer [BZ #17319]Mark Wielaard
TLS_INIT_TP in sysdeps/i386/nptl/tls.h uses some hand written asm to generate a set_thread_area that might result in exchanging ebx and esp around the syscall causing introspection tools like valgrind to loose track of the user stack. Just use INTERNAL_SYSCALL which makes sure esp isn't changed arbitrarily. Before the patch the code would generate: mov $0xf3,%eax movl $0xfffff,0x8(%esp) movl $0x51,0xc(%esp) xchg %esp,%ebx int $0x80 xchg %esp,%ebx Using INTERNAL_SYSCALL instead will generate: movl $0xfffff,0x8(%esp) movl $0x51,0xc(%esp) xchg %ecx,%ebx mov $0xf3,%eax int $0x80 xchg %ecx,%ebx Thanks to Florian Weimer for analysing why the original code generated the bogus esp usage: _segdescr.desc happens to be at the top of the stack, so its address is in %esp. The asm statement says that %3 is an input, so its value will not change, and GCC can use %esp as the input register for the expression &_segdescr.desc. But the constraints do not fully describe the asm statement because the %3 register is actually modified, albeit only temporarily. [BZ #17319] * sysdeps/i386/nptl/tls.h (TLS_INIT_TP): Use INTERNAL_SYSCALL to call set_thread_area instead of hand written asm. (__NR_set_thread_area): Removed define. (TLS_FLAG_WRITABLE): Likewise. (__ASSUME_SET_THREAD_AREA): Remove check. (TLS_EBX_ARG): Remove define. (TLS_LOAD_EBX): Likewise.
