* Move execve to syscalls.list (bug 14138).Joseph Myers2014-10-013-35/+7
| | | | | | | | | | | | | | Continuing the move of syscall definitions to syscalls.list, where previous cleanups have made this possible, this patch moves the definition of execve. (In this case, it was the removal of bounded pointers support, rather than old kernel support, which made the move possible.) Tested for x86_64. [BZ #14138] * sysdeps/unix/sysv/linux/execve.c: Remove file. * sysdeps/unix/sysv/linux/syscalls.list (execve): Add syscall.

* Move some *at definitions to syscalls.list (bug 14138).Joseph Myers2014-09-309-272/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Continuing the move of syscall definitions to syscalls.list, where the removal of support for old kernel versions has made this possible, this patch moves definitions of various *at functions in sysdeps/unix/sysv/linux/. These particular moves are straightforward: there are no #includes of these source files, no special architecture-specific versions, no special symbol version handling and no aliases. Each source file can be replaced by a single line in sysdeps/unix/sysv/linux/syscalls.list. Tested for x86_64. [BZ #14138] * sysdeps/unix/sysv/linux/syscalls.list (fchownat): New syscall.

* stdlib/tst-strtod-round.c: Fix build on ARMWill Newton2014-09-303-1/+9
| | | | | | | | | | | | | | | | | Building this test on ARM fails because the prototypes for the long double variants of the math functions are unavailable. Add an additional include guard to math.h that enables long double math function declarations if _LIBC_TEST is defined and define _LIBC_TEST in stdlib/tst-strtod-round.c. ChangeLog: 2014-09-30 Will Newton <will.newton@linaro.org> * math/math.h: Define long double math functions if _LIBC_TEST is defined. * stdlib/tst-strtod-round.c: Define _LIBC_TEST.

* Run tst-ld-sse-use.sh with bash.Joseph Myers2014-09-292-1/+6
| | | | | | | | | | | | | | tst-ld-sse-use.sh is a bash script, not a POSIX shell script, and so needs to be run with $(BASH) not $(SHELL) to avoid errors of the form: ../sysdeps/x86/tst-ld-sse-use.sh: 41: ../sysdeps/x86/tst-ld-sse-use.sh: declare: not found (when /bin/sh is dash). This patch makes that change. Tested for x86_64. * sysdeps/x86/Makefile ($(objpfx)tst-ld-sse-use.out): Run script with $(BASH) not $(SHELL).
* Correctly size profiling reloc table (bug 17411)Carlos O'Donell2014-09-293-3/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During auditing or profiling modes the dynamic loader builds a cache of the relocated PLT entries in order to reuse them when called again through the same PLT entry. This way the PLT entry is never completed and the call into the resolver always results in profiling or auditing code running. The problem is that the PLT relocation cache size is not computed correctly. The size of the cache should be "Size of a relocation result structure" x "Number of PLT-related relocations". Instead the code erroneously computes "Size of a relocation result" x "Number of bytes worth of PLT-related relocations". I can only assume this was a mistake in the understanding of the value of DT_PLTRELSZ which is the number of bytes of PLT-related relocs. We do have a DT_RELACOUNT entry, which is a count for dynamic relative relocs, but we have no DT_PLTRELCOUNT and thus we need to compute it. This patch corrects the computation of the size of the relocation table used by the glibc profiling code. For more details see: https://sourceware.org/ml/libc-alpha/2014-09/msg00513.html [BZ #17411] * elf/dl-reloc.c (_dl_relocate_object): Allocate correct amount for l_reloc_result.

* Remove shlib-versions entries redundant with DEFAULT entries.Joseph Myers2014-09-265-10/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a shlib-versions file has a DEFAULT line, it's not necessary to specify the same default minimum symbol version on the lines for individual libraries. If those lines otherwise duplicate the default SONAME for the library in question, they can be removed completely. This patch makes such cleanups: version entries for ld.so are removed (leaving just the definition of the architecture-specific dynamic linker name) and entries for libpthread are removed completely (since the default is libpthread.so.0). Tested for x86_64 that the installed shared libraries are unchanged by this patch. There are various architectures (hppa, ia64, mips, sh, sparc64) that define minimum symbol versions (or in the case of mips, omission of symbol versions) only for particular libraries without a DEFAULT line. None of these are equivalent to something simpler with a DEFAULT line because all have some other libraries, not explicitly mentioned, with symbol versions that would be omitted were such a line used. In the mips case I'm pretty sure it was a mistake not to omit the 2.1 symbols for libthread_db; for the others I don't know if it was a mistake or deliberate that some symbols in various libraries have 2.0 or 2.1 versions despite other libraries having a 2.2 minimum. This concludes the shlib-versions cleanups I'm aware of. * sysdeps/unix/sysv/linux/powerpc/powerpc64/shlib-versions: Do not specify symbol version for ld.so.

* Clean up gnu/lib-names.h generation (bug 14171).Joseph Myers2014-09-2616-65/+148
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch eliminates the mixture of SONAME information in shlib-versions files and SONAME information used to generate gnu/lib-names.h in makefiles, with the information in the makefiles being removed so all this information comes from the shlib-versions files. So that gnu/lib-names.h supports multiple ABIs, it is changed to be generated on the same basis as gnu/stubs.h: when there are multiple ABIs, gnu/lib-names.h is a wrapper header (the same header installed whatever ABI is being built) and separate headers such as gnu/lib-names-64.h contain the substantive contents (only one such header being installed by any glibc build). The rules for building gnu/lib-names.h were moved from Makeconfig to Makerules because they need to come after sysdeps makefiles are included (now that "ifndef abi-variants" is a toplevel conditional on the rules rather than $(abi-variants) being evaluated later inside the commands for a rule). Tested for x86_64 and x86 that the installed shared libraries are unchanged by this patch, and examined the installed gnu/lib-names*.h headers by hand. Also tested the case of a single ABI (where there is just a single header installed, again like stubs.h) by hacking abi-variants to empty for x86_64.

* Move some setrlimit definitions to syscalls.list (bug 14138).Joseph Myers2014-09-2311-43/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bug 14138 is followup cleanup after removal of support for old Linux kernel versions: moving syscalls to syscalls.list where the only reason for using C definitions was kernel version conditionals that are no longer present. This patch deals with the case of setrlimit (sysdeps/unix/sysv/linux/i386/setrlimit.c, included by various other architectures). Where needed (where there is also a compat symbol for setrlimit@GLIBC_2.0), new syscalls.list entries are added. Where not needed (where there is no such compat symbol and the minimum symbol version for libc is 2.2 or later), no such entries are added as that in sysdeps/unix/syscalls.list will suffice. Thus arm and sh need no such entries, while m68k and powerpc need entries only in a subdirectory syscalls.list file rather than for all configurations that previously used setrlimit.c. (setrlimit@@GLIBC_2.2 and setrlimit@GLIBC_2.0 are now semantically identical - the new symbol version was about a change of types from signed to unsigned and the former compatibility code for dealing with large unsigned arguments on old kernels is no longer needed or present, having been removed with support for pre-2.4 kernels. However, making the two versions into aliases doesn't work at present: the case of having both default and non-default symbol versions on the same syscalls.list line results in a compat_symbol call in code built for static libc, which doesn't compile. I don't suppose it would be hard to generate SHARED conditionals from make-syscalls.sh to fix this, but in any case this patch doesn't make things any worse, as the functions weren't aliases before the patch either.) Tested for x86, and ran ABI tests for ARM as an example of an architecture where the setrlimit.c file was just removed without adding syscalls.list entries.

The principle of removing this option was agreed in the thread starting at <https://sourceware.org/ml/libc-alpha/2013-07/msg00174.html>. Tested for x86_64 and x86 that the installed shared libraries other than libc.so are unchanged by this patch and that libc.so disassembly and symbol versions are unchanged (debug info changes because of changed line numbers in csu/version.c).

* Make __extern_always_inline usable on clang++ againSiddhesh Poyarekar2014-09-162-2/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The fix for BZ #17266 (884ddc5081278f488ef8cd49951f41cfdbb480ce) removed changes that had gone into cdefs.h to make __extern_always_inline usable with clang++. This patch adds back support for clang to detect if GNU inlining semantics are available, this time without breaking the gcc use case. The check put here is based on the earlier patch and assertion[1] that checking if __GNUC_STDC_INLINE__ or __GNUC_GNU_INLINE__ is defined is sufficient to determine that clang++ suports GNU inlining semantics. Tested with a simple program that builds with __extern_always_inline with the patch and fails compilation without it. #include <stdio.h> #include <sys/cdefs.h> extern void foo_alias (void) __asm ("foo"); __extern_always_inline void foo (void) { puts ("hi oh world!"); return foo_alias (); } void foo_alias (void) { puts ("hell oh world"); } int main () { foo (); } [1] https://sourceware.org/ml/libc-alpha/2012-12/msg00306.html [BZ #17266] * misc/sys/cdefs.h: Define __extern_always_inline for clang 4.2 and newer.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The check for only __GNUC_STDC_INLINE__ and __GNUC_GNU_INLINE__ may not be sufficient since those flags were added during initial support for C99 inlining semantics. There is also a problem with always defining __extern_inline and __extern_always_inline, since it enables inline wrapper functions even when GNU inlining semantics are not guaranteed. This, along with the possibility of such wrappers using redirection (btowc for example) could result in compiler generating an infinitely recusrive call to the function. In fact it was such a recursion that led to this code being written the way it was; see: https://bugzilla.redhat.com/show_bug.cgi?id=186410 The initial change was to fix bugs 14530 and 13741, but they can be resolved by checking if __fortify_function and/or __extern_always_inline are defined, as it has been done in this patch. In addition, I have audited uses of __extern_always_inline to make sure that none of the uses result in compilation errors. There is however a regression in this patch for llvm, since it reverts the llvm expectation that __GNUC_STDC_INLINE__ or __GNUC_GNU_INLINE__ definition imply proper extern inline semantics. 2014-09-16 Siddhesh Poyarekar <siddhesh@redhat.com> Jakub Jelinek <jakub@redhat.com> [BZ #17266] * libio/stdio.h: Check definition of __fortify_function instead of __extern_always_inline to include bits/stdio2.h. * math/bits/math-finite.h [__USE_XOPEN || __USE_ISOC99]: Also check if __extern_always_inline is defined.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* Use %ifdef in sysdeps/unix/sysv/linux/powerpc/powerpc64/shlib-versions.Joseph Myers2014-09-125-2/+21
| | | | | | | | | | | | | | | | | | | | | | | 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].
* Move OS-specific shlib-versions entries to sysdeps files.Joseph Myers2014-09-124-22/+21
| | | | | | | | | | | | | | | | | | | | | | | 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.
* Move architecture-specific shlib-versions entries to sysdeps files.Joseph Myers2014-09-128-18/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* Add new Linux 3.16 constants to netinet/udp.h.Joseph Myers2014-09-122-0/+9
| | | | | | | | | | | | | 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.

* Complete the removal of __gconv_translit_findFlorian Weimer2014-09-1220-287/+75
| | | | | | | | | 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.
* Enhance tst-xmmymm.sh to detect zmm register usage in ld.so (BZ #16194)Siddhesh Poyarekar2014-09-123-6/+14
| | | | | | | | | | | | | | | | 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.

* Return failure in getnetgrent only when all netgroups have been searched ↵Siddhesh Poyarekar2014-09-103-1/+16
| | | | | | | | | | | | | | | | (#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.
* PowerPC: memset optimization for POWER8/PPC64Adhemerval Zanella2014-09-108-9/+533
| | | | | | | | | | | | | | | | | | | 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.
* PowerPC: multiarch bzero cleanup for PPC64Adhemerval Zanella2014-09-1011-91/+32
| | | | | | | | 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).
