2019-03-01ldbl-opt: Add argp_error and argp_failure (bug 23983)Gabriel F. T. Gomes
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.

2019-02-18misc/tst-clone3: Fix waiting for exited thread.Stefan Liebler
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.
2019-02-15io: Consolidate lockf implementationAdhemerval Zanella
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). Checked on i686-linux-gnu and x86_64-linux-gnu along with a i686-gnu build. * io/Makefile (tests): Add tst-lockf. * io/lockf.c (lockf): Use __fcntl and only define for !__OFF_T_MATCHES_OFF64_T. * io/lockf64.c (__lockf64): Call __fcntl64 and alias to lockf for __OFF_T_MATCHES_OFF64_T case. * io/tst-lockf.c: New file. * sysdeps/unix/sysv/linux/i386/lockf64.c: Remove file. * sysdeps/unix/sysv/linux/arm/lockf64.c: Likewise. * sysdeps/unix/sysv/linux/m68k/lockf64.c: Likewise. * sysdeps/unix/sysv/linux/mips/mips32/lockf64.c: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n32/lockf64.c: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc32/lockf64.c: Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/lockf64.c: Likewise. * sysdeps/unix/sysv/linux/sh/lockf64.c: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc32/lockf64.c: Likewise.
2019-02-14nptl: Reinstate pthread_timedjoin_np as a cancellation point (BZ#24215)Adhemerval Zanella
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.

2019-02-13RISC-V: Fix elfutils testsuite unwind failures.Jim Wilson
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?

2019-02-06Avoid "inline" after return type in function definitions.Joseph Myers
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.

2019-01-03nptl: Cleanup cancellation macrosAdhemerval Zanella
This patch wraps all uses of *_{enable,disable}_asynccancel and and *_CANCEL_{ASYNC,RESET} in either already provided macros (lll_futex_timed_wait_cancel) or creates new ones if the functionality is not provided (SYSCALL_CANCEL_NCS, lll_futex_wait_cancel, and lll_futex_timed_wait_cancel). Also for some generic implementations, the direct call of the macros are removed since the underlying symbols are suppose to provide cancellation support.

2019-01-03posix: Clear close-on-exec for posix_spawn adddup2 (BZ#23640)Adhemerval Zanella
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). Checked on aarch64-linux-gnu.

This patch updates the Linux kernel version in tst-mman-consts.py to 4.20 (meaning that's the version for which glibc is expected to have the same constants as the kernel, up to the exceptions listed in the test).

2019-01-02ARM: fix kernel assisted atomics with GCC 8 (bug 24034)Aurelien Jarno
The pre-ARMv7 CPUs are missing atomic compare and exchange and/or barrier instructions. Therefore those are implemented using kernel assistance, calling a kernel function at a specific address, and passing the arguments in the r0 to r4 registers. This is done by specifying registers for local variables. The a_ptr variable is placed in the r2 register and declared with __typeof (mem). According to the GCC documentation on local register variables, if mem is a constant pointer, the compiler may substitute the variable with its initializer in asm statements, which may cause the corresponding operand to appear in a different register. This happens in __libc_start_main with the pointer to the thread counter for static binaries (but not the shared ones): # ifdef SHARED unsigned int *ptr = __libc_pthread_functions.ptr_nthreads; # ifdef PTR_DEMANGLE PTR_DEMANGLE (ptr); # endif # else extern unsigned int __nptl_nthreads __attribute ((weak)); unsigned int *const ptr = &__nptl_nthreads; # endif This causes static binaries using threads to crash when the GNU libc is built with GCC 8 and most notably tst-cancel21-static. To fix that, use the same trick than for the volatile qualifier, defining a_ptr as a union. Changelog: [BZ #24034] * sysdeps/unix/sysv/linux/arm/atomic-machine.h (__arm_assisted_compare_and_exchange_val_32_acq): Use uint32_t rather than __typeof (...) for the a_ptr variable.

This patch adds the IPV6_MULTICAST_ALL constant from Linux 4.20 to bits/in.h. Tested for x86_64. * sysdeps/unix/sysv/linux/bits/in.h (IPV6_MULTICAST_ALL): New macro.
2019-01-01Add PACKET_IGNORE_OUTGOING from Linux 4.20 to netpacket/packet.h.Joseph Myers
This patch adds the PACKET_IGNORE_OUTGOING constant from Linux 4.20 to netpacket/packet.h. Tested for x86_64. * sysdeps/unix/sysv/linux/netpacket/packet.h (PACKET_IGNORE_OUTGOING): New macro.
2019-01-01Add HWCAP_SSBS from Linux 4.20 to AArch64 bits/hwcap.h.Joseph Myers
This patch adds the HWCAP_SSBS constant from Linux 4.20 to the AArch64 bits/hwcap.h. Tested with build-many-glibcs.py for aarch64-linux-gnu. * sysdeps/unix/sysv/linux/aarch64/bits/hwcap.h (HWCAP_SSBS): New macro.
2019-01-01Update syscall-names.list for Linux 4.20.Joseph Myers
This patch updates sysdeps/unix/sysv/linux/syscall-names.list for Linux 4.20. Although there are no new syscalls, the riscv_flush_icache syscall has moved to asm/unistd.h (previously in asm/syscalls.h) and so now needs to be added to the list. Tested with build-many-glibcs.py. * sysdeps/unix/sysv/linux/syscall-names.list: Update kernel version to 4.20. (riscv_flush_icache): New syscall.

2018-12-31riscv: Use __has_include__ to include <asm/syscalls.h> [BZ #24022]H.J. Lu
<asm/syscalls.h> has been removed by commit 27f8899d6002e11a6e2d995e29b8deab5aa9cc25 Author: David Abdurachmanov <david.abdurachmanov@gmail.com> Date: Thu Nov 8 20:02:39 2018 +0100 riscv: add asm/unistd.h UAPI header Marcin Juszkiewicz reported issues while generating syscall table for riscv using 4.20-rc1. The patch refactors our unistd.h files to match some other architectures. - Add asm/unistd.h UAPI header, which has __ARCH_WANT_NEW_STAT only for 64-bit - Remove asm/syscalls.h UAPI header and merge to asm/unistd.h - Adjust kernel asm/unistd.h So now asm/unistd.h UAPI header should show all syscalls for riscv. <asm/syscalls.h> may be restored by Subject: [PATCH] riscv: restore asm/syscalls.h UAPI header Date: Tue, 11 Dec 2018 09:09:35 +0100 UAPI header asm/syscalls.h was merged into UAPI asm/unistd.h header, which did resolve issue with missing syscalls macros resulting in glibc (2.28) build failure. It also broke glibc in a different way: asm/syscalls.h is being used by glibc. I noticed this while doing Fedora 30/Rawhide mass rebuild. The patch returns asm/syscalls.h header and incl. it into asm/unistd.h. I plan to send a patch to glibc to use asm/unistd.h instead of asm/syscalls.h In the meantime, we use __has_include__, which was added to GCC 5, to check if <asm/syscalls.h> exists before including it. Tested with build-many-glibcs.py for riscv against kernel 4.19.12 and 4.20-rc7. [BZ #24022] * sysdeps/unix/sysv/linux/riscv/flush-icache.c: Check if <asm/syscalls.h> exists with __has_include__ before including it.
2018-12-21Update nios2, sparc32 localplt.data for difftime changes (bug 24023).Joseph Myers
The recent difftime changes introduced localplt test failures on nios2 and sparc32, two configurations where some soft-fp functions are defined in / exported from libc.so, and where the difftime changes affected the particular set of floating-point operations used in libc.so. This patch adds those functions to localplt.data, alongside other such functions already there. (In the sparc32 case, and more generally on any platform where long double is a software floating-point type, it would probably be more efficient to avoid using long double at all in difftime, but that's a pre-existing issue.) Tested with build-many-glibcs.py for its nios2 and sparcv9 configurations. [BZ #24023] * sysdeps/unix/sysv/linux/nios2/localplt.data: Allow __floatundidf PLT reference in libc.so. * sysdeps/unix/sysv/linux/sparc/sparc32/localplt.data: Allow _Q_lltoq and _Q_qtod PLT references in libc.so.
