* Add LFS support for fts functions (bug 11460)Mark Wielaard2015-11-061-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | fts didn't have large-file support yet and fts.h had an #error preventing usage when _FILE_OFFSET_BITS was set. This required nasty workarounds for programs using fts with LFS. This patch implements LFS support for fts by adding FTS64 and FTENT64 variants plus fts64 functions. Which are simple aliases for 64bit off_t arches. Also includes a simple testcase for some of the fts functions with or without LFS enabled. [BZ #11460] * io/Makefile (routines): Add fts64. (tests): Add tst-fts and tst-fts-lfs. (CFLAGS-fts64.c): New. * io/Versions (GLIBC_2.23): New. * io/fts.c: Replace FTS with FTSOBJ, FTSENT with FTSENTRY. Use function defines FTS_OPEN, FTS_CLOSE, FTS_READ, FTS_SET and FTS_CHILDREN. Define FTSOBJ, FTSENTRY, FTS_OPEN, FTS_CLOSE, FTS_READ, FTS_SET, FTS_CHILDREN, INO_T, STAT and LSTAT if necessary. * io/fts.h (FTS64): New if _USE_LARGEFILE64. (FTSENT64): Likewise.

In most cases, there are no errors. But we still call __x86.get_pc_thunk.reg. This patch adds INLINE_SYSCALL_ERROR_RETURN_VALUE so that i386 can optimize setting errno by branching to the internal __syscall_error without PLT.

* alpha: drop __ASSUME_FDATASYNCMike Frysinger2015-09-173-52/+0
| | | | | | Since we require a new enough kernel all the time, the __ASSUME_FDATASYNC define has been hardcoded to 1. That means we can delete the alpha file for fdatasync now and rely on the syscalls list like other ports.
* libio: fmemopen rewrite to POSIX complianceAdhemerval Zanella2015-07-081-0/+3

It fixes some long-stading glibc fmemopen issues, such as: * it changes the way fseek with SEEK_END works on fmemopen to seek relative to buffer size instead of first '\0'. This is default mode and 'b' opening mode does not change internal behavior (bz#6544). * fix apending opening mode to use as start position either first null byte of len specified in function call (bz#13152 and #13151). * remove binary option 'b' and internal different handling (bz#12836) * fix seek/SEE_END with negative values (bz#14292). A compatibility symbol is provided to with old behavior for older symbols version (2.2.5). * include/stdio.h (fmemopen): Remove hidden prototype. (__fmemopen): Add new hidden prototype. * libio/Makefile: Add oldfmemopen object. * libio/Versions [GLIBC_2.22]: Add new fmemopen symbol. * libio/fmemopen.c (__fmemopen): Function rewrite to be POSIX compliance. * libio/oldfmemopen.c: New file: old fmemopen implementation for symbol compatibility. * stdio-common/Makefile [tests]: Add new tst-fmemopen3. * stdio-common/psiginfo.c [psiginfo]: Call __fmemopen instead of fmemopen. * stdio-common/tst-fmemopen3.c: New file: more fmemopen tests, focus on append and read mode. * sysdeps/unix/sysv/linux/aarch64/libc.abilist [GLIBC_2.22]: Add fmemopen. * sysdeps/unix/sysv/linux/alpha/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/arm/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/i386/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/ia64/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/m68k/coldfire/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/m68k/m680x0/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/microblaze/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/mips/mips32/fpu/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/mips/mips32/nofpu/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n32/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n64/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc32/fpu/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc32/nofpu/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc64/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/s390/s390-64/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/sh/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc32/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc64/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/tile/tilegx/tilegx32/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/tile/tilegx/tilegx64/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/tile/tilepro/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/x86_64/64/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/x86_64/x32/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/hppa/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/nios2/libc.abilist [GLIBC_2.22]: Likewise.

* Fix semaphore destruction (bug 12674).Carlos O'Donell2015-01-211-5/+0
| | | | | | | | | | | | | This commit fixes semaphore destruction by either using 64b atomic operations (where available), or by using two separate fields when only 32b atomic operations are available. In the latter case, we keep a conservative estimate of whether there are any waiting threads in one bit of the field that counts the number of available tokens, thus allowing sem_post to atomically both add a token and determine whether it needs to call futex_wake.

* Fix libm feraiseexcept namespace (bug 17723).Joseph Myers2014-12-301-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Various C90 and UNIX98 libm functions call feraiseexcept, which is not in those standards. This causes linknamespace test failures - except on x86 / x86_64, where feraiseexcept is inline (for the relevant constant arguments) in bits/fenv.h. This patch fixes this by making those functions call __feraiseexcept instead. All changes are applied to all architectures rather than considering the possibility that some might not be needed in some cases (e.g. x86) as it seems most maintainable to keep architectures consistent. Where __feraiseexcept does not exist, it is added, with feraiseexcept made a weak alias; where it is a strong alias, it is made weak. libm_hidden_def / libm_hidden_proto are used with __feraiseexcept (this might in some cases improve code generation for existing calls to __feraiseexcept in some code on some architectures). Where there are dummy feraiseexcept macros (on architectures without floating-point exceptions support, to avoid compile errors from references to undefined FE_* macros), corresponding dummy __feraiseexcept macros are added. And on x86, to ensure __feraiseexcept calls still get inlined, the inline function in bits/fenv.h is refactored so that most of it can be reused in an inline __feraiseexcept in a separate include/bits/fenv.h. Calls are changed in C90/UNIX98 functions, but generally not in functions missing from those standards. They are also changed in libc_fe* functions (on the basis that those might be used in any libm function), and in feupdateenv (on the same basis - may be used, via default libc_*, in any libm function - of course feupdateenv will need changing to __feupdateenv in a subsequent patch to make that fully namespace-clean). No __feraiseexcept is added corresponding to the feraiseexcept in powerpc bits/fenvinline.h, because that macro definition is conditional on !defined __NO_MATH_INLINES, and glibc libm is built with -D__NO_MATH_INLINES, so changing internal calls to use __feraiseexcept should make no difference. Tested for x86_64 (testsuite; the only change in disassembly of installed shared libraries is a slight code reordering in clog10, of no apparent significance). Also tested for MIPS, where (in the configuration tested) it eliminates math.h linknamespace failures for n32 and n64 (some for o32 remain because of other issues).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For maximum paranoia we run ld.so through the normal set of tests for all of the shared libraries. This includes running ld.so through check-localplt, check-textrel, and check-execstack. While none of these should trigger any failures given the way ld.so is built, it might possibly fail if a developer does something wrong. This paranoia was triggered by a discussion over the use of __strcpy vs. strcpy [1] and if the symbol could leak and use the libc.so version. The check-localplt test fails right away because localplt.data needs updating for all arches. By default we add 6 new symbols: __tls_get_addr, __libc_memalign, malloc, calloc, realloc and free. Other machines like i386, power, and s390 require some different symbol sets e.g. ___tls_get_addr vs. __tls_get_addr for i386.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | glibc has lots of __libc_* function names that no longer serve any purpose (are not used for any calls or exported at a public symbol version).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

* Move architecture shlib-versions files to Linux-specific directories.Joseph Myers2014-07-171-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

* Remove __ASSUME_ATFCTS conditionals in sysdeps/unix/sysv/linux/.Joseph Myers2014-06-202-70/+2

Several fchownat.c files that were only present because of differences in the fallback syscalls used (depending on the architecture-specific names of chown-related syscalls for 32-bit uids) are removed. Files that looks like they could be replaced by syscalls.list entries have the standard "Consider moving to syscalls.list." comment (see bug 14138) added. Conditionals on the relevant __NR_* syscall numbers being defined are also removed, since my analysis indicated that the relevant syscalls are always defined for all relevant kernel versions using any affected file. Much of the removed fallback code had unbounded stack allocations, so this reduces the number of cases to consider for anyone reviewing uses of alloca and VLAs in glibc. There remain tests of __ASSUME_ATFCTS in io/openat.c (to determine whether to define __have_atfcts) and sysdeps/posix/getcwd.c (which also uses __have_atfcts); thus, the definition of __ASSUME_ATFCTS remains in kernel-features.h. The logical condition relevant there is whether openat64_not_cancel_3 is known to work. Hurd doesn't use this version of getcwd at all, so the conditionals in getcwd.c are always true in glibc. However, this code is also used in gnulib. So the best way to deal with the conditionals there may be for gnulib people to deal with merging all relevant changes in both directions between the glibc and gnulib versions of this file, at the end of which the openat conditionals should be in whatever form is best for gnulib, and hardcoded in the _LIBC case to having openat supported. Tested by comparing before-and-after disassembly of installed (stripped) shared libraries, on x86_64 and x86. On x86 the patch made no change to the disassembly; on x86_64, the only changes were in readlinkat, where formerly the return value from the readlinkat syscall was stored in an int variable before being converted to ssize_t for the return, and now the return value is returned directly without truncation to int. I think it's clearly correct not to truncate the return value (although I also think the truncation would not have been a user-visible bug because the kernel would never have returned a value it could have affected). * include/fcntl.h (__atfct_seterrno): Remove prototype.

* Add adaptive elision to rwlocksAndi Kleen2014-06-131-0/+2
| | | | | | | | | | | | | | | | | | | This patch relies on the C version of the rwlocks posted earlier. With C rwlocks it is very straight forward to do adaptive elision using TSX. It is based on the infrastructure added earlier for mutexes, but uses its own elision macros. The macros are fairly general purpose and could be used for other elision purposes too. This version is much cleaner than the earlier assembler based version, and in particular implements adaptation which makes it safer. I changed the behavior slightly to not require any changes in the test suite and fully conform to all expected behaviors (generally at the cost of not eliding in various situations). In particular this means the timedlock variants are not elided. Nested trylock aborts.

Specifically, __ASSUME_O_CLOEXEC (O_CLOEXEC flag to open) and __ASSUME_SOCK_CLOEXEC (SOCK_NONBLOCK and SOCK_CLOEXEC flags to socket) are supported on all architectures as of 2.6.32 or the minimum kernel version for the architecture if later. For __ASSUME_IN_NONBLOCK, __ASSUME_PIPE2, __ASSUME_EVENTFD2, __ASSUME_SIGNALFD4 and __ASSUME_DUP3, the relevant syscalls were added for alpha in 2.6.33 but otherwise the features are available as of 2.6.32. For __ASSUME_UTIMES, support is everywhere in 2.6.32 except for asm-generic architectures and hppa. Although those were the main cases of duplication among kernel-features.h files, some other cases of unnecessary definitions were also cleaned up: the hppa file defined various macros that were either no longer used at all, or defined by the main file by default anyway, the ia64 file had duplicative definitions of __ASSUME_PSELECT and __ASSUME_PPOLL, while mips had such a definition of __ASSUME_IPC64. Really, rather than being defined in the main file then undefined for asm-generic architectures, __ASSUME_UTIMES should become an hppa-specific macro. Given that __ASSUME_ATFCTS and __ASSUME_UTIMENSAT are now always true, the only live __ASSUME_UTIMES conditional is in sysdeps/unix/sysv/linux/utimes.c, which is not used for asm-generic architectures. I think the desired state would be an hppa-specific file (that includes sysdeps/unix/sysv/linux/utimes.c if __ASSUME_UTIMES, and otherwise has fallback code), with the fallback code being removed from the main utimes.c. But I think that's most reasonably a separate cleanup once __ASSUME_ATFCTS and __ASSUME_UTIMESAT have both had conditional code cleaned up. Given this patch, I think it's straightforward to move non-ex-ports architectures to having their own kernel-features.h files, like ex-ports architectures, rather than conditionals in the main file (i.e., such a move won't require the architecture-specific file to contain anything that isn't genuinely architecture-specific), and would encourage architecture maintainers to do so. Tested x86_64 that the installed shared libraries are unchanged by this patch. Note that on some architectures this *will* cause __ASSUME_* macros to be defined in cases where they weren't previously but should have been (but this is just optimization, not a fix to a user-visible bug, so doesn't need a bug report in Bugzilla). * sysdeps/unix/sysv/linux/kernel-features.h (__ASSUME_UTIMES): Define unconditionally.

Nothing actually tests __ASSUME_RECVMMSG for function availability, but implicit in the definition in kernel-features.h is the idea that it makes sense when the syscall is available and socketcall is not being used. As with accept4, there are architectures where the syscall was added later than the socketcall operation, meaning that assuming glibc is built with recent enough kernel headers, it does not attempt to use socketcall for these operations and __ASSUME_RECVMMSG gets defined for kernels >= 2.6.33 even when the syscall was only added later. This patch splits the macro into separate macros like those used for accept4; having similar macro structure in both cases (and for sendmmsg once I've dealt with that) seems likely to be less confusing than having a different structure on the basis of nothing actually needing to assume the recvmmsg function works. Appropriate definitions are added for all architectures. Architecture-specific note: Tile's kernel-features.h says "TILE glibc support starts with 2.6.36", which is accurate in that 2.6.36 was the first kernel version with Tile support, and on that basis I've made that header define __ASSUME_RECVMMSG_SYSCALL unconditionally. However, Tile's configure.ac has arch_minimum_kernel=2.6.32. Since arch_minimum_kernel is meant to reflect only kernel.org kernel versions, I think that should change to 2.6.36. (If using glibc with kernel versions from before a port went in kernel.org, it's your responsibility to change arch_minimum_kernel in a local patch, and at the same time to adjust any __ASSUME_* definitions that may not be correct for your older kernel; for developing the official glibc it should only ever be necessary to consider what official kernel.org releases support.)

* Fix __ASSUME_ACCEPT4 issues (bug 16609).Joseph Myers2014-02-201-3/+3

As previously noted, __ASSUME_ACCEPT4 is used in two ways: * In OS-independent code, to mean "accept4 can be assumed to work rather than fail with ENOSYS". It doesn't matter whether it's implemented with socketcall or a separate syscall. * In Linux-specific code, to mean "the socketcall multiplex syscall can be assumed to handle the accept4 operation. When used in Linux-specific code, it *never* refers to anything relating to the accept4 syscall, only to the socketcall multiplexer. This patch splits the macro into separate __ASSUME_ACCEPT4_SOCKETCALL, __ASSUME_ACCEPT4_SYSCALL and __ASSUME_ACCEPT4 to clarify the different cases involved. A macro __ASSUME_SOCKETCALL is added for convenience in writing logic relating to all socketcall architectures. In addition, to address the issue of architectures where socketcall support for accept4 was added before a separate syscall was added (and so the separate syscall should not be used unless known to be present or fallback to socketcall is available), a fourth macro __ASSUME_ACCEPT4_SYSCALL_WITH_SOCKETCALL is added to indicate that the syscall became available at the same time as socketcall support. This is then used in the relevant places in a conditional determining whether to undefine __NR_accept4 (the simple approach to avoiding the syscall's presence causing problems; I didn't try to implement runtime fallback from the syscall to socketcall). Architecture-specific note: alpha defined __ASSUME_ACCEPT4 for 2.6.33 and later, but actually the syscall was added for alpha in 3.2, so this patch uses the correct condition for __ASSUME_ACCEPT4_SYSCALL there. Tested x86_64, including that disassembly of the installed shared libraries is unchanged by this patch.

The only non-mechanical part of this patch is the changes to features.h; everything else is simple substitution of __USE_MISC for the old macros. Thus, this patch leaves obviously redundant conditionals such as "defined __USE_MISC || defined __USE_MISC", and does not update #endif comments where they referred to BSD or SVID in words instead of the literal macro name. This is intended to facilitate patch review by separating the less mechanical changes from these purely mechanical changes into a separate patch. (I do intend to integrate all the changes from <https://sourceware.org/ml/libc-alpha/2013-12/msg00226.html>, which I believe includes all the trailing comment updates, in subsequent patches.)
