* S390: Add new hwcap values for new cpu architecture arch13.Stefan Liebler2019-03-221-0/+4
| | | | | | | | | | | | | | | | | | | | | | The new hwcap values indicate support for: -"Vector-Enhancements Facility 2" (tag "vxe2", hwcap 2^15) -"Vector-Packed-Decimal-Enhancement Facility" (tag "vxp", hwcap 2^16) -"Enhanced-Sort Facility" (tag "sort", hwcap 2^17) -"Deflate-Conversion Facility" (tag "dflt", hwcap 2^18) The vxe2 hwcap is also marked as important hwcap. ChangeLog: * sysdeps/s390/dl-procinfo.c (_dl_s390_cap_flags): Add vxe2, vxp, dflt, sort flags. * sysdeps/s390/dl-procinfo.h: Add HWCAP_S390_VXRS_EXT2, HWCAP_S390_VXRS_PDE, HWCAP_S390_SORT, HWCAP_S390_DFLT capabilities. (HWCAP_IMPORTANT): Add HWCAP_S390_VXRS_EXT2. * sysdeps/unix/sysv/linux/s390/bits/hwcap.h (HWCAP_S390_VXRS_EXT2, HWCAP_S390_VXRS_PDE, HWCAP_S390_SORT, HWCAP_S390_DFLT): Define.
* Add AArch64 HWCAPs from Linux 5.0.Joseph Myers2019-03-192-2/+6
| | | | | | | | | | | | | | | | This patch adds new AArch64 HWCAPs from Linux 5.0 to the AArch64 bits/hwcap.h and dl-procinfo.c. Tested (compilation only) with build-many-glibcs.py for aarch64-linux-gnu. * sysdeps/unix/sysv/linux/aarch64/bits/hwcap.h (HWCAP_SB): New macro. (HWCAP_PACA): Likewise. (HWCAP_PACG): Likewise. * sysdeps/unix/sysv/linux/aarch64/dl-procinfo.c (_DL_HWCAP_COUNT): Increase to 32. (_dl_aarch64_cap_flags): Add new entries for new HWCAPs.
* Update syscall-names.list for Linux 5.0.Joseph Myers2019-03-151-2/+3
| | | | | | | | | | | | | | | | This patch updates sysdeps/unix/sysv/linux/syscall-names.list for Linux 5.0. Based on testing with build-many-glibcs.py, the only new entry needed is for old_getpagesize (a newly added __NR_* name for an old syscall on ia64). (Because 5.0 changes how syscall tables are handled in the kernel, checking diffs wasn't a useful way of looking for new syscalls in 5.0 as most of the syscall tables were moved to the new representation without actually adding any syscalls to them.) Tested with build-many-glibcs.py. * sysdeps/unix/sysv/linux/syscall-names.list: Update kernel version to 5.0. (old_getpagesize): New syscall.
* Remove obsolete, never-implemented XSI STREAMS declarationsFlorian Weimer2019-03-1410-76/+0
| | | | | | | | | | | | | | | | | | | The stub implementations are turned into compat symbols. Linux actually has two reserved system call numbers (for getpmsg and putpmsg), but these system calls have never been implemented, and there are no plans to implement them, so this patch replaces the wrappers with the generic stubs. According to <https://bugzilla.redhat.com/show_bug.cgi?id=436349>, the presence of the XSI STREAMS declarations is a minor portability hazard because they are not actually implemented. This commit does not change the TIRPC support code in sunrpc/rpc_svcout.c. It uses additional XTI functionality and therefore never worked with glibc. Reviewed-by: Carlos O'Donell <carlos@redhat.com>
* Fix output of LD_SHOW_AUXV=1.Stefan Liebler2019-03-133-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Starting with commit 1616d034b61622836d3a36af53dcfca7624c844e the output was corrupted on some platforms as _dl_procinfo was called for every auxv entry and on some architectures like s390 all entries were represented as "AT_HWCAP". This patch is removing the condition and let _dl_procinfo decide if an entry is printed in a platform specific or generic way. This patch also adjusts all _dl_procinfo implementations which assumed that they are only called for AT_HWCAP or AT_HWCAP2. They are now just returning a non-zero-value for entries which are not handled platform specifc. ChangeLog: * elf/dl-sysdep.c (_dl_show_auxv): Remove condition and always call _dl_procinfo. * sysdeps/unix/sysv/linux/s390/dl-procinfo.h (_dl_procinfo): Ignore types other than AT_HWCAP. * sysdeps/sparc/dl-procinfo.h (_dl_procinfo): Likewise. * sysdeps/unix/sysv/linux/i386/dl-procinfo.h (_dl_procinfo): Likewise. * sysdeps/powerpc/dl-procinfo.h (_dl_procinfo): Adjust comment in the case of falling back to generic output mechanism. * sysdeps/unix/sysv/linux/arm/dl-procinfo.h (_dl_procinfo): Likewise.
* C-SKY: mark lr as undefined to stop unwindingMao Han2019-03-112-2/+7
| | | | | | | | | | Mark the lr register as undefined at the start of execution, so unwind will stop at this frame. run-backtrace-*.sh from elfutils testsuite will fail without this patch. * sysdeps/csky/abiv2/start.S: Mark lr as undefined. * sysdeps/unix/sysv/linux/csky/abiv2/clone.S: Likewise. * sysdeps/unix/sysv/linux/csky/abiv2/setcontext.S: Likewise.
* C-SKY: remove user_regs definitionMao Han2019-03-112-46/+12
| | | | | | | | | | | | C-SKY GDB dose not use this file for ptrace and coredump. ptrace can use pt_regs definition from linux kernel directly. The old definition only got 34 regs instead of 38 regs from linux kernel, which will corrupted the memory after ptrace PTRACE_GETREGSET call. * sysdeps/unix/sysv/linux/csky/sys/procfs.h: Use linux definition directly. * sysdeps/unix/sysv/linux/csky/sys/user.h: Remove user_regs definition.
* C-SKY: fix sigcontext miss matchMao Han2019-03-112-66/+62
| | | | | | | | | | | | C-SKY defines SIGCONTEXT as siginfo_t *_si, struct ucontext_t * for __profil_counter. ucontext_t get an extra __mask field which is miss match with the struct sigcontext from linux kernel. The time value from gprof report will be always zero without this patch. This patch also fix the registers sequence in register-dump.h. * sysdeps/unix/sysv/linux/csky/register-dump.h: Adjust offset change. * sysdeps/unix/sysv/linux/csky/sys/ucontext.h: Remove __mask field in mcontext_t

| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes further coding style issues where code should have broken lines before operators in accordance with the GNU Coding Standards but instead was breaking lines after them. Tested for x86_64, and with build-many-glibcs.py. * stdio-common/vfscanf-internal.c (ARG): Break lines before rather than after operators. * sysdeps/mach/hurd/setitimer.c (timer_thread): Likewise.

* nptl: Assume __ASSUME_FUTEX_CLOCK_REALTIME supportAdhemerval Zanella2019-03-053-218/+0
| | | | | | | | | | | | | | | | | | | | | | | | | This patch assumes realtime clock support for nptl and thus removes all the associated code. For __pthread_mutex_timedlock the fallback usage for the case where lll_futex_timed_wait_bitset it not set define is also removed. The generic lowlevellock-futex.h always define it, so for NPTL code the check always yield true. Checked on x86_64-linux-gnu and i686-linux-gnu. * nptl/nptl-init.c (__have_futex_clock_realtime, __have_futex_clock_realtime): Remove definition. (__pthread_initialize_minimal_internal): Remove FUTEX_CLOCK_REALTIME check test for !__ASSUME_FUTEX_CLOCK_REALTIME. * nptl/pthread_mutex_timedlock.c (__pthread_mutex_timedlock): Assume __ASSUME_FUTEX_CLOCK_REALTIME support. * sysdeps/unix/sysv/linux/i386/lowlevellock.S: Likewise. * sysdeps/unix/sysv/linux/x86_64/lowlevellock.S: Likewise. * sysdeps/unix/sysv/linux/kernel-features.h (__ASSUME_FUTEX_CLOCK_REALTIME): Remove. * sysdeps/nptl/lowlevellock-futex.h (lll_futex_timed_wait_bitset): Adjust comment.
* ldbl-opt: Add error and error_at_line (bug 23984)Gabriel F. T. Gomes2019-03-018-0/+16
| | | | | | | | | | On platforms where long double may have the same format as double (-mlong-double-64), error and error_at_line do not take that into account and might produce wrong output if a long double conversion is requested by the format string ('%Lf'). This patch adds compatibility functions for this situation and redirects calls via header magic. Tested for powerpc, powerpc64 and powerpc64le.
* ldbl-opt: Add err, errx, verr, verrx, warn, warnx, vwarn, and vwarnx (bug 23984)Gabriel F. T. Gomes2019-03-018-0/+64
| | | | | | | | | | | | | | | When support for long double format with 128-bits (-mlong-double-128) was added for platforms where long double had the same format as double, such as powerpc, compatibility versions for the functions listed in the commit title were missed. Since the older format of long double can still be used (with -mlong-double-64), using these functions with a format string that requests the printing of long double variables will produce wrong outputs. This patch adds the missing compatibility functions and header magic to redirect calls to them when -mlong-double-64 is in use. Tested for powerpc, powerpc64 and powerpc64le.
* ldbl-opt: Add argp_error and argp_failure (bug 23983)Gabriel F. T. Gomes2019-03-018-0/+16
| | | | | | | | | | The functions argp_error and argp_failure are missing support for printing long double values when long double has the same format as double. This patch adds the new functions __nldbl_argp_error and __nldbl_argp_failure, as well as header magic to redirect calls to them when -mlong-double-64 is in use. Tested for powerpc, powerpc64 and powerpc64le.

* misc/tst-clone3: Fix waiting for exited thread.Stefan Liebler2019-02-181-8/+15
| | | | | | | | | | | | | | | | | | | | | | | From time to time the test misc/tst-clone3 fails with a timeout. Then futex_wait is blocking. Usually ctid should be set to zero due to CLONE_CHILD_CLEARTID and the futex should be waken up. But the fail occures if the thread has already exited before ctid is set to the return value of clone(). Then futex_wait() will block as there will be nobody who wakes the futex up again. This patch initializes ctid to a known value before calling clone and the kernel is the only one who updates the value to zero after clone. If futex_wait is called then it is either waked up due to the exited thread or the futex syscall fails as *ctid_ptr is already zero instead of the specified value 1. ChangeLog: * sysdeps/unix/sysv/linux/tst-clone3.c (do_test): Initialize ctid with a known value and remove update of ctid after clone. (wait_tid): Adjust arguments and call futex_wait with ctid_val as assumed current value of ctid_ptr.
* io: Consolidate lockf implementationAdhemerval Zanella2019-02-159-78/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With internal fcntl64 internal (commit 06ab719d), it is possible to consolidate lockf implementation by using the LFS fcntl interface instead of using arch and system-specific implementations. For Linux, the i386 implementation is used as generic implementation by replacing the direct syscall with fcntl64 call. The LFS symbol alias for default LFS ABI (__OFF_T_MATCHES_OFF64_T) is used to avoid the duplicate symbol (instead of overriding the implementation with an empty file). For Hurd lockf64 semantic is changed: previous generic lockf64 implementation returned EOVERFLOW if LEN input is larger than 32-bit off_t. However, Hurd fcntl64 implementation for F_GETLK64, F_SETLK64, and F_SETLKW64 do accept off64_t inputs (__f_setlk accepts only off64_t inputs).

* nptl: Reinstate pthread_timedjoin_np as a cancellation point (BZ#24215)Adhemerval Zanella2019-02-148-226/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch ce7eb0e90315 ("nptl: Cleanup cancellation macros") changed the join sequence for internal common __pthread_timedjoin_ex to use the new macro lll_wait_tid. The idea was this macro would issue the cancellable futex operation depending whether the timeout is used or not. However if a timeout is used, __lll_timedwait_tid is called and it is not a cancellable entrypoint. This patch fixes it by simplifying the code in various ways: - Instead of adding the cancellation handling on __lll_timedwait_tid, it moves the generic implementation to pthread_join_common.c (called now timedwait_tid with some fixes to use the correct type for pid). - The llvm_wait_tid macro is removed, along with its replication on x86_64, i686, and sparc arch-specific lowlevellock.h. - sparc32 __lll_timedwait_tid is also removed, since the code is similar to generic one. - x86_64 and i386 provides arch-specific __lll_timedwait_tid which is also removed since they are similar in functionality to generic C code and there is no indication it is better than compiler generated code. New tests, tst-join8 and tst-join9, are provided to check if pthread_timedjoin_np acts as a cancellation point. Checked on x86_64-linux-gnu, i686-linux-gnu, sparcv9-linux-gnu, and aarch64-linux-gnu.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The clone.S patch fixes 2 elfutils testsuite unwind failures, where the backtrace gets stuck repeating __thread_start until we hit the backtrace limit. This was confirmed by building and installing a patched glibc and then building elfutils and running its testsuite. Unfortunately, the testcase isn't working as expected and I don't know why. The testcase passes even when my clone.S patch is not installed. The testcase looks logically similarly to the elfutils testcases that are failing. Maybe there is a subtle difference in how the glibc unwinding works versus the elfutils unwinding? I don't have good gdb pthread support yet, so I haven't found a way to debug this. Anyways, I don't know if the testcase is useful or not. If the testcase isn't useful then maybe the clone.S patch is OK without a testcase?

* Avoid "inline" after return type in function definitions.Joseph Myers2019-02-061-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | One group of warnings seen with -Wextra is warnings for static or inline not at the start of a declaration (-Wold-style-declaration). This patch fixes various such cases for inline, ensuring it comes at the start of the declaration (after any static). A common case of the fix is "static inline <type> __always_inline"; the definition of __always_inline starts with __inline, so the natural change is to "static __always_inline <type>". Other cases of the warning may be harder to fix (one pattern is a function definition that gets rewritten to be static by an including file, "#define funcname static wrapped_funcname" or similar), but it seems worth fixing these cases with inline anyway.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Austin Group issue #411 [1] proposes that posix_spawn file action posix_spawn_file_actions_adddup2 resets the close-on-exec when source and destination refer to same file descriptor. It solves the issue on multi-thread applications which uses close-on-exec as default, and want to hand-chose specifically file descriptor to purposefully inherited into a child process. Current approach to achieve this scenario is to use two adddup2 file actions and a temporary file description which do not conflict with any other, coupled with a close file action to avoid leaking the temporary file descriptor. This approach, besides being complex, may fail with EMFILE/ENFILE file descriptor exaustion. This can be more easily accomplished with an in-place removal of FD_CLOEXEC. Although the resulting adddup2 semantic is slight different than dup2 (equal file descriptors should be handled as no-op), the proposed possible solution are either more complex (fcntl action which a limited set of operations) or results in unrequired operations (dup3 which also returns EINVAL for same file descriptor).
