* Move architecture shlib-versions files to Linux-specific directories.Joseph Myers2014-07-171-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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). Tested x86_64 that the installed shared libraries are unchanged by this patch. * sysdeps/aarch64/shlib-versions: Move to ... * sysdeps/unix/sysv/linux/aarch64/shlib-versions: ... here. * sysdeps/alpha/shlib-versions: Move to ... * sysdeps/unix/sysv/linux/alpha/shlib-versions: ... here. * sysdeps/arm/shlib-versions: Move to ... * sysdeps/unix/sysv/linux/arm/shlib-versions: ... here. * sysdeps/hppa/shlib-versions: Move all contents except for libgcc_s entry to ... * sysdeps/unix/sysv/linux/hppa/shlib-versions: ... here.

* Remove __ASSUME_ATFCTS conditionals in sysdeps/unix/sysv/linux/.Joseph Myers2014-06-201-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch cleans up for __ASSUME_ATFCTS now always being true for the supported Linux kernel versions by removing conditional code in sysdeps/unix/sysv/linux. 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.

* Reduce kernel-features.h duplication.Joseph Myers2014-05-141-14/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch reduces duplication between different architectures' kernel-features.h files by making the architecture-independent file define various macros unconditionally (instead of only for a particular list of architectures), with the architecture-specific files then undefining the macros if necessary. 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.

* Correct robust mutex / PI futex kernel assumptions (bug 9894).Joseph Myers2014-03-311-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch continues fixing __ASSUME_* issues in preparation for moving to a 2.6.32 minimum kernel version by addressing assumptions on robust mutex and PI futex support availability. Those assumptions are bug 9894, but to be clear this patch does not address all the issues from that bug about wrong version assumptions, only those still applicable for --enable-kernel=2.6.32 or later (with the expectation that the move to that minimum kernel will obsolete the other parts of the bug). The patch is independent of <https://sourceware.org/ml/libc-alpha/2014-03/msg00585.html>, my other pending-review patch preparing for the kernel version change; the two together complete all the changes I believe are needed in preparation regarding any macro in sysdeps/unix/sysv/linux/kernel-features.h that would be affected by such a change. (I have not checked the correctness of macros whose conditions are unaffected by such a change, or macros only defined in other kernel-features.h files.) As discussed in that bug, robust mutexes and PI futexes need futex_atomic_cmpxchg_inatomic to be implemented, in addition to certain syscalls needed for robust mutexes (and architecture-independent kernel pieces for all the features in question). That is, as I understand it, they need futex_atomic_cmpxchg_inatomic to *work* (not return an ENOSYS error). The issues identified in my analysis relate to ARM, M68K, MicroBlaze, MIPS and SPARC. On ARM, whether futex_atomic_cmpxchg_inatomic works depends on the kernel configuration. As of 3.13, the condition for *not* working is CONFIG_CPU_USE_DOMAINS && CONFIG_SMP. As of 2.6.32 it was simply CONFIG_SMP that meant the feature was not implemented. I don't know if there are any circumstances in which we can say "we can assume a userspace glibc binary built with these options will never run on a kernel with the problematic configuration", but at least for now I'm just undefining the relevant __ASSUME_* macros for ARM. On M68K, two of the three macros are undefined for kernels before 3.10, but as far as I can see __ASSUME_FUTEX_LOCK_PI is in the same group needing futex_atomic_cmpxchg_inatomic support and so should be undefined as well. On MicroBlaze the required support was added in 2.6.33. On MIPS, the support depends on cpu_has_llsc in the kernel - that is, actual hardware LL/SC support (GCC and glibc for MIPS GNU/Linux rely on the instructions being supported in some way, but it may be kernel emulation; futex_atomic_cmpxchg_inatomic doesn't work with that emulation). The same condition as in GCC for indicating LL/SC support may not be available is used for undefining the macros in glibc, __mips == 1 || defined _MIPS_ARCH_R5900. (Maybe we could in fact desupport MIPS processors without the hardware support in glibc.) On SPARC, 32-bit kernels don't support futex_atomic_cmpxchg_inatomic; __arch64__ || __sparc_v9__ is used as the condition for binaries that won't run on 32-bit kernels. This patch is not tested beyond the sanity check of an x86_64 build.

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.
