2015-11-06Simplify the abilist formatFlorian Weimer1-58/+9
The new format lists the version on each line, as in: VERSION SYMBOL TYPE [VALUE] This makes it easier to process the files with line-oriented tools. The abilist files were converted with this awk script: /^[^ ]/ { version = $1 } /^ / { print version, substr($0, 2) } And sorted under the "C" locale with sort.
2015-11-05Add script to list fixed bugs for the NEWS file.Joseph Myers1-0/+46
This patch adds a script to list fixed bugs for the NEWS file, as proposed in <https://sourceware.org/ml/libc-alpha/2015-10/msg01043.html>, with the bugs listed in the format proposed in <https://sourceware.org/ml/libc-alpha/2015-11/msg00088.html>. * scripts/list-fixed-bugs.py: New file.

Linker in binutils 2.26 and newer generate GOT references instead PLT references when -z now is passed to linker. We need to extend scripts/localplt.awk to allow PLT or GOT references. [BZ #19007] * scripts/localplt.awk: Also allow GOT references. * sysdeps/unix/sysv/linux/i386/localplt.data: Mark _Unwind_Find_FDE, calloc, memalign, realloc and __libc_memalign with "+ REL R_386_GLOB_DAT". * sysdeps/x86_64/localplt.data: Mark calloc, memalign, realloc and __libc_memalign with "+ RELA R_X86_64_GLOB_DAT".
2015-10-06Remove scripts/rpm2dynsym.sh.Joseph Myers1-36/+0
The file scripts/rpm2dynsym.sh appears to be unused anywhere in glibc. This patch removes this script. Tested for x86_64 and x86 (testsuite, and that installed shared libraries are unchanged by the patch). * scripts/rpm2dynsym.sh: Remove file.

On x86, linker in binutils 2.26 and newer consolidates R_*_JUMP_SLOT with R_*_GLOB_DAT relocation against the same symbol. This patch extends local PLT reference check to support alternate relocations. [BZ #18078] * scripts/check-localplt.awk: Support alternate relocations. * scripts/localplt.awk: Also check relocations in DT_RELA/DT_REL sections. * sysdeps/unix/sysv/linux/i386/localplt.data: Mark free and malloc entries with + REL R_386_GLOB_DAT. * sysdeps/x86_64/localplt.data: New file.

2015-01-02Update copyright dates not handled by scripts/update-copyrights.Joseph Myers1-1/+1
I've updated copyright dates in glibc for 2015. This is the patch for the changes not generated by scripts/update-copyrights and subsequent build / regeneration of generated files. Apart from the files updated last time (of which sotruss.ksh had moved to sotruss.sh during the year) this also updates nptl/version.c (missed from 2006 until October) and sysdeps/unix/sysv/linux/lddlibc4.c (missed since 2009). * NEWS: Update copyright dates. * catgets/gencat.c (print_version): Likewise. * csu/version.c (banner): Likewise. * debug/catchsegv.sh: Likewise. * debug/pcprofiledump.c (print_version): Likewise. * debug/xtrace.sh (do_version): Likewise. * elf/ldconfig.c (print_version): Likewise. * elf/ldd.bash.in: Likewise. * elf/pldd.c (print_version): Likewise. * elf/sotruss.sh: Likewise. * elf/sprof.c (print_version): Likewise. * iconv/iconv_prog.c (print_version): Likewise. * iconv/iconvconfig.c (print_version): Likewise. * locale/programs/locale.c (print_version): Likewise. * locale/programs/localedef.c (print_version): Likewise. * login/programs/pt_chown.c (print_version): Likewise. * malloc/memusage.sh (do_version): Likewise. * malloc/memusagestat.c (print_version): Likewise. * malloc/mtrace.pl: Likewise. * manual/libc.texinfo: Likewise. * nptl/version.c (banner): Likewise. * nscd/nscd.c (print_version): Likewise. * nss/getent.c (print_version): Likewise. * nss/makedb.c (print_version): Likewise. * posix/getconf.c (main): Likewise. * scripts/test-installation.pl: Likewise. * sysdeps/unix/sysv/linux/lddlibc4.c (main): Likewise.

2015-01-02Remove uses of sprintf in gen-posix-conf-vars.awkSiddhesh Poyarekar1-5/+2
Simply some code by replacing sprintf in the awk script.
2014-12-31Use one-dimension arrays in gen-posix-conf-vars.awkSiddhesh Poyarekar1-23/+23
True multi-dimensional arrays were introduced in awk 4.0 and we support awk versions as early as 3.12. Use a single subscript of the form prefix_conf instead of two dimensions to work around this limitation. We also need one additional array of just the conf names subscripted by the prefix_conf to print the names for the specifications. * scripts/gen-posix-conf-vars.awk: Don't use multi-dimensional arrays.
2014-12-29Make type for spec variable size as size_tSiddhesh Poyarekar1-1/+1
2014-12-29Use posix-conf-vars.list to generate spec arraySiddhesh Poyarekar1-0/+28
This patch adds support to generate the spec array in getconf from the conf.list. The generated code is mostly unchanged. the only changes are due to the change in layout of the spec and val arrays in the ELF. The val array can also be auto-generated from posix-conf-vars.list once the remaining macros are added to it. * posix/posix-conf-vars.list (SPEC:XBS5): Add sysconf prefix. * posix/confstr.c: Define NEED_SPEC_ARRAY to 0. * posix/posix-envs.def: Likewise. * sysdeps/posix/sysconf.c: Likewise. * posix/getconf.c: Define NEED_SPEC_ARRAY to 1. (specs): Remove array. * scripts/gen-posix-conf-vars.awk: Support generation of specs array.
2014-12-29Remove Wundef warnings for specification macrosSiddhesh Poyarekar1-0/+61
This patch adds a file posix-conf-vars.list that is used to generate macros to determine if a macro is defined as set, unset or not defined. gen-posix-conf-vars.awk processes this file and generates a header (posix-conf-vars-def.h) with these macros. A new header posix-conf-vars.h includes this generated header and defines accessor macros for the generated macros. Tested on x86_64. * posix/Makefile (before-compile): Add posix-conf-vars-def.h. ($(objpfx)posix-conf-vars-def.h): New target. * posix/posix-conf-vars.list: New file. * posix/posix-conf-vars.h: New file. * posix/confstr.c: Include posix-conf-vars.h. (confstr): Use CONF_IS_* macros. * posix/posix-envs.def: Include posix-conf-vars.h. Use CONF_IS_* macros. * scripts/gen-posix-conf-vars.awk: New file.
2014-11-19Auto-generate libc-modules.hSiddhesh Poyarekar1-0/+34
Remove libc-modules.h from the tree and auto-generate it from soversions.i and the list of modules in the built-modules variable defined in Makeconfig. Macros generated have increasing numbered values, with built-modules having lower values starting from 1, following which a separator value LIBS_BEGIN is added and then finally the library names from soversions.i are appended to the list. This allows us to conveniently differentiate between the versioned libraries and other built modules, which is needed in errno.h and netdb.h to decide whether to use an internal symbol or an external one. Verified that generated code remains unchanged on x86_64. * Makeconfig (built-modules): List non-library modules to be built. (module-cppflags): Include libc-modules.h for everything except shlib-versions.v.i. (CPPFLAGS): Use it. (before-compile): Add libc-modules.h. ($(common-objpfx)libc-modules.h, $(common-objpfx)libc-modules.stmp): New targets. (common-generated): Add libc-modules.h and libc-modules.stmp. ($(common-objpfx)Versions.v.i): Depend on libc-modules.h. * include/libc-symbols.h: Don't include libc-modules.h. * include/libc-modules.h: Remove file. * scripts/gen-libc-modules.awk: New script to generate libc-modules.h. * sysdeps/unix/Makefile ($(common-objpfx)sysd-syscalls): Depend on libc-modules.stmp.
2014-09-26Clean up gnu/lib-names.h generation (bug 14171).Joseph Myers1-2/+1
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 $(abi-variants) being evaluated later inside the commands for a rule). Tested for x86_64 and x86 that the installed shared libraries are unchanged by this patch, and examined the installed gnu/lib-names*.h headers by hand. Also tested the case of a single ABI (where there is just a single header installed, again like stubs.h) by hacking abi-variants to empty for x86_64. [BZ #14171] * Makeconfig [$(build-shared) = yes] ($(common-objpfx)soversions.mk): Don't handle SONAMEs specified in makefiles. [$(build-shared) = yes && $(soversions.mk-done) = t] ($(common-objpfx)gnu/lib-names.h): Remove rule.

2014-09-16Remove bitrotten --enable-oldest-abi (bug 6652).Joseph Myers2-10/+1
This patch removes the --enable-oldest-abi configure option, which has long been bitrotten (as reported in bug 6652). 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). [BZ #6652] * Makeconfig (soversions-default-setname): Remove variable. ($(common-objpfx)soversions.i): Don't pass default_setname to soversions.awk. * Makerules ($(common-objpfx)abi-versions.h): Don't pass oldest_abi to abi-versions.awk. * config.h.in (GLIBC_OLDEST_ABI): Remove macro undefine. * config.make.in (oldest-abi): Remove variable. * configure.ac (--enable-oldest-abi): Remove configure option. * configure: Regenerated. * csu/version.c (banner) [GLIBC_OLDEST_ABI]: Remove conditional text. * scripts/abi-versions.awk: Do not handle oldest_abi variable. * scripts/soversions.awk: Do not handle default_setname variable. * sysdeps/mach/hurd/configure.ac: Do not handle oldest_abi variable. * sysdeps/mach/hurd/configure: Regenerated. * sysdeps/unix/sysv/linux/configure.ac: Do not handle oldest_abi variable. * sysdeps/unix/sysv/linux/configure: Regenerated.
2014-09-12Remove configuration name patterns from shlib-versions.Joseph Myers1-41/+23
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.
2014-06-27Remove shlib-versions ABI names support.Joseph Myers1-13/+0
shlib-versions files can contain ABI lines that map triplets to a canonical ABI name. This name was once used for various purposes where test baseline files for different ABIs went in a single directory; now these purposes use sysdeps files, generation of headers which have per-ABI variants uses abi-variants and related Makefile variables and the shlib-versions ABI names are unused. This patch duly removes those lines and associated build system support for them. Tested for x86_64 (both a full testsuite run and confirming the installed shared libraries are unchanged by the patch). * Makeconfig ($(common-objpfx)soversions.mk): Do not generate abi-name definition. * scripts/soversions.awk: Do not handle or generate ABI lines. * shlib-versions: Remove ABI entries. * sysdeps/powerpc/nofpu/shlib-versions: Remove file. * sysdeps/x86_64/x32/shlib-versions: Remove ABI entry.
2014-06-26Update scripts/list-sources.sh for ports repository merge.Joseph Myers1-14/+0
scripts/list-sources.sh includes handling of ports that has been obsolete ever since the ports repository was merged into the libc repository. This patch removes that handling. Tested by regenerating libc.pot and examining the resulting changes. * scripts/list-sources.sh: Do not handle ports specially.
2014-06-26Update miscellaneous files from upstream sources.Joseph Myers4-362/+189
This patch updates miscellaneous files from their upstream sources: texinfo.tex from Texinfo, config.guess and config.sub from config.git, install-sh from automake and move-if-change from gnulib. Tested x86_64 that installed shared libraries are unchanged by the patch; also looked at the generated libc.pdf manual. * manual/texinfo.tex: Update to version 2014-05-05.10 with trailing whitespace removed. * scripts/config.guess: Update to version 2014-03-23. * scripts/config.sub: Update to version 2014-05-01 * scripts/install-sh: Update to version 2013-12-25.23. * scripts/move-if-change: Update from gnulib.
2014-06-16Pass $TIMEOUTFACTOR to tests also in cross testingAndreas Schwab1-1/+1
2014-06-06Don't require test wrappers to preserve environment variables, use more ↵Joseph Myers1-23/+22
consistent environment. One wart in the original support for test wrappers for cross testing, as noted in <https://sourceware.org/ml/libc-alpha/2012-10/msg00722.html>, is the requirement for test wrappers to pass a poorly-defined set of environment variables from the build system to the system running the glibc under test. Although some variables are passed explicitly via $(test-wrapper-env), including LD_* variables that simply can't be passed implicitly because of the side effects they'd have on the build system's dynamic linker, others are passed implicitly, including variables such as GCONV_PATH and LOCPATH that could potentially affect the build system's libc (so effectively relying on any such effects not breaking the wrappers). In addition, the code in cross-test-ssh.sh for preserving environment variables is fragile (it depends on how bash formats a list of exported variables, and could well break for multi-line variable definitions where the contents contain things looking like other variable definitions). This patch moves to explicitly passing environment variables via $(test-wrapper-env). Makefile variables that previously used $(test-wrapper) are split up into -before-env and -after-env parts that can be passed separately to the various .sh files used in testing, so those files can then insert environment settings between the two parts. The common default environment settings in make-test-out are made into a separate makefile variable that can also be passed to scripts, rather than many scripts duplicating those settings (for testing an installed glibc, it is desirable to have the GCONV_PATH setting on just one place, so just that one place needs to support it pointing to an installed sysroot instead of the build tree). The default settings are included in the variables such as $(test-program-prefix), so that if tests do not need any non-default settings they can continue to use single variables rather than the split-up variables. Although this patch cleans up LC_ALL=C settings (that being part of the common defaults), various LANG=C and LANGUAGE=C settings remain. Those are generally unnecessary and I propose a subsequent cleanup to remove them. LC_ALL takes precedence over LANG, and while LANGUAGE takes precedence over LC_ALL, it only does so for settings other than LC_ALL=C. So LC_ALL=C on its own is sufficient to ensure the C locale, and anything that gets LC_ALL=C does not need the other settings. While preparing this patch I noticed some tests with .sh files that appeared to do nothing beyond what the generic makefile support for tests can do (localedata/tst-wctype.sh - the makefiles support -ENV variables and .input files - and localedata/tst-mbswcs.sh - just runs five tests that could be run individually from the makefile). So I propose another subsequent cleanup to move those to using the generic support instead of special .sh files.
