* Move execve to syscalls.list (bug 14138).Joseph Myers2014-10-012-35/+1
| | | | | | | | | | | | | | 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 Myers2014-09-308-272/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Remove shlib-versions entries redundant with DEFAULT entries.Joseph Myers2014-09-264-10/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Myers2014-09-2611-22/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Myers2014-09-2310-43/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Remove bitrotten --enable-oldest-abi (bug 6652).Joseph Myers2014-09-162-12/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

* Remove configuration name patterns from shlib-versions.Joseph Myers2014-09-1217-71/+71
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.)

* Use %ifdef in sysdeps/unix/sysv/linux/powerpc/powerpc64/shlib-versions.Joseph Myers2014-09-123-2/+10
| | | | | | | | | | | | | | | | | | | | | | | 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 Myers2014-09-121-0/+2
| | | | | | | | | | | | | | | | | | | | | | | 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 Myers2014-09-125-0/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Fix powerpc32 __get_clockfreq for non-power4 (bug 17263).Joseph Myers2014-08-131-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In my powerpc32 testing I've observed misc/test-gettimebasefreq failing. This is a glibc build (soft-float, though that's not relevant here) without any --with-cpu and without any special configuration of the default CPU for GCC either. In particular, it's one not using sysdeps/powerpc/powerpc32/power4/hp-timing.h (although in fact the processor I'm using for testing is POWER4-based), so hp_timing_t is 32-bit not 64-bit. But the VDSO call being used by INTERNAL_VSYSCALL_NO_SYSCALL_FALLBACK is generating a 64-bit result (high part in r3, low part in r4). The code extracting that result, however, expects a result of the type hp_timing_t as passed to INTERNAL_VSYSCALL_NO_SYSCALL_FALLBACK, meaning that only r3 (= 0) is used and the value in r4 is ignored. This patch fixes this by always using uint64_t as the type in INTERNAL_VSYSCALL_NO_SYSCALL_FALLBACK - reflecting the actual ABI (unconditional in the kernel) of that VDSO call. This is the minimal change for this issue - no check for overflow, no change of the type of the timebase_freq variable or the return type of __get_clockfreq to something other than hp_timing_t (such a change would simply move the implicit conversions to the over callers of that function), no change to hp_timing_t itself. Tested for powerpc32 soft float. [BZ #17263] * sysdeps/unix/sysv/linux/powerpc/get_clockfreq.c: Include <stdint.h>. (__get_clockfreq): Use uint64_t instead of hp_timing_t in INTERNAL_VSYSCALL_NO_SYSCALL_FALLBACK call.
* PowerPC: Fix termios definitionsAdhemerval Zanella2014-08-062-50/+73
| | | | | | | | | | | This patch fixes the incorrect guard by __USE_MISC of struct winsize and struct termio in powerpc termios header. Current states leads to build failures if the program defines _XOPEN_SOURCE, but not _DEFAULT_SOURCE or either _BSD_SOURCE or _SVID_SOURCE. Without any definition, __USE_MISC will not be defined and neither the struct definitions. This patch copies the default Linux ioctl-types.h by adjusting only the character control field (c_cc) size in struct termio.

* ia64: define nocancel entry points in PSEUDOMike Frysinger2014-08-041-0/+19
| | | | | | | | | | | | | | The previous set of not-cancel.h headers (prior to the commit 2fbdf5339aaeaa423bd661524f7ec7af41fa2606) did not require the arch to define nocancel entry points, so ia64 never did. However, after the various files were merged, it became a hard requirement for arches which mean ia64 failed to build. Here we add dedicated entry points. It'd be nice to merge with the existing stubs like other arches do, but the ia64 asm does not lend itself to interleaving of functions. If someone has a suggestion on merging these, that'd be great, but at least now we build & pass tests again.

* Refactor handling of /lib64 etc. cases, move out of sysdeps/gnu/configure.ac.Joseph Myers2014-07-1714-88/+136
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch continues removing architecture-specific cases from non-architecture-specific files by moving the logic to use directories such as /lib64 out of sysdeps/gnu/configure.ac. A new macro LIBC_SLIBDIR_RTLDDIR is created that sysdeps configure scripts can use to declare the library directories to be used; the logic was previously duplicated in configure fragments for aarch64, mips and x32 as well as in sysdeps/gnu/configure.ac. This macro is used directly in sysdeps/gnu/configure.ac only to provide the /lib default (the logic saying that with --prefix=/usr shared libraries go in /lib not /usr/lib); the architecture cases formerly there are moved into various new or existing configure.ac files. The new macro is also used in the various architecture fragments that already had such logic. In the x32 there was previously a configure fragment, but it was a directly written one without a .ac file; now a .ac file is used there instead to generate configure. Tested x86_64 that the installed shared libraries, and the directory structure of the installation, are unchanged by this patch. There is an old bug report - bug 6441 - about library directories changing after reconfiguring. If this is still applicable - and I haven't attempted to confirm it or review the old patch pointed to in that bug - then this patch should reduce the number of places needing changing in any fix. * aclocal.m4 (LIBC_SLIBDIR_RTLDDIR): New macro. * sysdeps/gnu/configure.ac: Use LIBC_SLIBDIR_RTLDDIR. Remove cases for individual architectures. * sysdeps/gnu/configure: Regenerated. * sysdeps/unix/sysv/linux/aarch64/configure.ac: Use LIBC_SLIBDIR_RTLDDIR. * sysdeps/unix/sysv/linux/aarch64/configure: Regenerated. * sysdeps/unix/sysv/linux/mips/configure.ac: Use LIBC_SLIBDIR_RTLDDIR. * sysdeps/unix/sysv/linux/mips/configure: Regenerated. * sysdeps/unix/sysv/linux/powerpc/powerpc64/configure.ac: Use LIBC_SLIBDIR_RTLDDIR. * sysdeps/unix/sysv/linux/powerpc/powerpc64/configure: Regenerated. * sysdeps/unix/sysv/linux/s390/s390-64/configure.ac: New file. * sysdeps/unix/sysv/linux/s390/s390-64/configure: New generated file. * sysdeps/unix/sysv/linux/sparc/sparc64/configure.ac: New file. * sysdeps/unix/sysv/linux/sparc/sparc64/configure: New generated file. * sysdeps/unix/sysv/linux/x86_64/64/configure.ac: New file. * sysdeps/unix/sysv/linux/x86_64/64/configure: New generated file. * sysdeps/unix/sysv/linux/x86_64/x32/configure.ac: New file. * sysdeps/unix/sysv/linux/x86_64/x32/configure: Generate.
* Move architecture shlib-versions files to Linux-specific directories.Joseph Myers2014-07-1711-0/+80
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Various architectures have files such as sysdeps/<arch>/shlib-versions whose contents are in fact entirely Linux-specific, relating only to the symbol / shared library versions for the port to Linux on that architecture, when any future port to a different OS on that architecture would use the symbol version of the glibc release it goes in, as standard for new ports. This patch moves such files under sysdeps/unix/sysv/linux/, merging in the contents of sysdeps/<arch>/nptl/shlib-versions in the process. The only bits not moved are those relating to libgcc_s versions, which don't appear OS-specific in the same way that glibc's symbol versions so. It deliberately does not change the regular expressions given for matching configurations in each file; some match only Linux although not Linux-specific, or match other OSes although Linux-specific. It is with a view to at least the following further cleanups: * Move architecture-specific content from the toplevel shlib-versions and nptl/shlib-versions into sysdeps shlib-versions files, so eliminating another difference between ex-ports and non-ex-ports architectures. * Likewise, for OS-specific content in shlib-versions files. * At that point, the first field in shlib-versions files (the regular expression matching a configuration triplet) should be redundant, so eliminate that field and leave shlib-versions selection working purely on a sysdeps basis (with limited use of %ifdef in shlib-versions files when needed) rather than having its own separate mechanism to select what configuration information is relevant. * Move the build of gnu/lib-names.h to a similar mechanism to that used for gnu/stubs.h (each library build installing a version of the header specifically for that build), so we can eliminate the duplication of soname information in the makefiles and get it purely from shlib-versions files again. There may be other cleanups possible as well (in particular, I'm not sure that all cases where the same "Earliest symbol set" information is repeated for many different libraries actually should need to repeat it rather than specifying it just once for DEFAULT for the given configuration, and separately specifying any non-default choices of soname).
