* [PATCH] pthread_once hangs when init routine throws an exception [BZ #18435]Jakub Jelinek2021-03-043-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This is another attempt at making pthread_once handle throwing exceptions from the init routine callback. As the new testcases show, just switching to the cleanup attribute based cleanup does fix the tst-once5 test, but breaks the new tst-oncey3 test. That is because when throwing exceptions, only the unwind info registered cleanups (i.e. C++ destructors or cleanup attribute), when cancelling threads and there has been unwind info from the cancellation point up to whatever needs cleanup both unwind info registered cleanups and THREAD_SETMEM (self, cleanup, ...) registered cleanups are invoked, but once we hit some frame with no unwind info, only the THREAD_SETMEM (self, cleanup, ...) registered cleanups are invoked. So, to stay fully backwards compatible (allow init routines without unwind info which encounter cancellation points) and handle exception throwing we actually need to register the pthread_once cleanups in both unwind info and in the THREAD_SETMEM (self, cleanup, ...) way. If an exception is thrown, only the former will happen and we in that case need to also unregister the THREAD_SETMEM (self, cleanup, ...) registered handler, because otherwise after catching the exception the user code could call deeper into the stack some cancellation point, get cancelled and then a stale cleanup handler would clobber stack and probably crash. If a thread calling init routine is cancelled and unwind info ends before the pthread_once frame, it will be cleaned up through self->cleanup as before. And if unwind info is present, unwind_stop first calls the self->cleanup registered handler for the frame, then it will call the unwind info registered handler but that will already see __do_it == 0 and do nothing.
* nptl: Move elision implementations into libcFlorian Weimer2021-02-231-0/+29
| | | | | | | | | | | | | | | | | | The elision interfaces are closely aligned between the targets that implement them, so declare them in the generic <lowlevellock.h> file. Empty .c stubs are provided, so that fewer makefile updates under sysdeps are needed. Also simplify initialization via __libc_early_init. The symbols __lll_clocklock_elision, __lll_lock_elision, __lll_trylock_elision, __lll_unlock_elision, __pthread_force_elision move into libc. For the time being, non-hidden references are used from libpthread to access them, but once that part of libpthread is moved into libc, hidden symbols will be used again. (Hidden references seem desirable to reduce the likelihood of transactions aborts.)
* linux: Fix __sem_check_add_mapping search_semAdhemerval Zanella2021-02-091-1/+1

* linux: Fix __sem_check_add_mapping name lengthAdhemerval Zanella2021-02-091-0/+1
| | | | | | | | Take in consideration the trailling NULL since sem_search uses strcmp to compare entries. Checked on x86_64-linux-gnu and powerpc-linux-gnu (where it triggered a nptl/tst-sem7 regression).
* pthread: Remove alloca usage from __sem_check_add_mappingAdhemerval Zanella2021-02-081-6/+17

* pthread: Refactor semaphore codeAdhemerval Zanella2021-02-084-165/+221
| | | | | | | | | | | The internal semaphore list code is moved to a specific file, sem_routine.c, and the internal usage is simplified to only two functions (one to insert a new semaphore and one to remove it from the internal list). There is no need to expose the internal locking, neither how the semaphore mapping is implemented. No functional or semantic change is expected, tested on x86_64-linux-gnu.
* linux: Require /dev/shm as the shared memory file systemFlorian Weimer2021-02-082-18/+26
| | | | | | | | | | | | | | | | | | | | | Previously, glibc would pick an arbitrary tmpfs file system from /proc/mounts if /dev/shm was not available. This could lead to an unsuitable file system being picked for the backing storage for shm_open, sem_open, and related functions. This patch introduces a new function, __shm_get_name, which builds the file name under the appropriate (now hard-coded) directory. It is called from the various shm_* and sem_* function. Unlike the SHM_GET_NAME macro it replaces, the callers handle the return values and errno updates. shm-directory.c is moved directly into the posix subdirectory because it can be implemented directly using POSIX functionality. It resides in libc because it is needed by both librt and nptl/htl. In the sem_open implementation, tmpfname is initialized directly from a string constant. This happens to remove one alloca call. Checked on x86_64-linux-gnu.
* Update copyright dates with scripts/update-copyrightsPaul Eggert2021-01-02257-257/+257
| | | | | | | | | | | | | | | | I used these shell commands: ../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright (cd ../glibc && git commit -am"[this commit message]") and then ignored the output, which consisted lines saying "FOO: warning: copyright statement not found" for each of 6694 files FOO. I then removed trailing white space from benchtests/bench-pthread-locks.c and iconvdata/tst-iconv-big5-hkscs-to-2ucs4.c, to work around this diagnostic from Savannah: remote: *** pre-commit check failed ... remote: *** error: lines with trailing whitespace found remote: error: hook declined to update refs/heads/master

* y2038: Convert aio_suspend to support 64 bit timeLukasz Majewski2020-11-301-25/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The aio_suspend function has been converted to support 64 bit time. This change uses (in aio_misc.h): - __futex_abstimed_wait64 (instead of futex_reltimed_wait) - __futex_abstimed_wait_cancellable64 (instead of futex_reltimed_wait_cancellable) from ./sysdeps/nptl/futex-helpers.h The aio_suspend() accepts relative timeout, which then is converted to absolute one. The i686-gnu port (HURD) do not define DONT_NEED_AIO_MISC_COND and as it doesn't (yet) support 64 bit time it uses not converted pthread_cond_timedwait(). The __aio_suspend() is supposed to be run on ports with __TIMESIZE !=64 and __WORDSIZE==32. It internally utilizes __aio_suspend_time64() and hence the conversion from 32 bit struct timespec to 64 bit one is required. For ports supporting 64 bit time the __aio_suspend_time64() will be used either via alias (to __aio_suspend when __TIMESIZE==64) or redirection (when -D_TIME_BITS=64 is passed).

* nptl: Fix PTHREAD_PRIO_PROTECT timed lockAdhemerval Zanella2020-11-272-2/+23
| | | | | | | | | | | | | | | | | The 878fe624d4 changed lll_futex_timed_wait, which expects a relative timeout, with a __futex_abstimed_wait64, which expects an absolute timeout. However the code still passes a relative timeout. Also, the PTHREAD_PRIO_PROTECT support for clocks different than CLOCK_REALTIME was broken since the inclusion of pthread_mutex_clocklock (9d20e22e46) since lll_futex_timed_wait always use CLOCK_REALTIME. This patch fixes by removing the relative time calculation. It also adds some xtests that tests both thread and inter-process usage. Checked on x86_64-linux-gnu.

| | | | | | | | | | | | | | | | #26801] Linux futex FUTEX_LOCK_PI operation only supports CLOCK_REALTIME, so pthread_mutex_clocklock operation with priority aware mutexes may fail depending of the input timeout.

* C11 threads: Fix inaccuracies in testsuiteCorinna Vinschen2020-09-073-3/+3
| | | | | | | | | | | | | | | | - tst-mtx-recursive.c: mtx_init fails to use mtx_plain. Per C11 specs, using mtx_recursive alone is not supported. This isn't catched because mtx_plain is defined as 0. - tst-thrd-sleep.c: thrd_sleep returns 0 on success, a negative value on failure. Testing against thrd_success is incorrect. - tst-tss-basic.c: tss_set is incorrectly checkd for a non-0 value. The test should test aginst C11 threads error codes. This isn't catched because thrd_success is defined as 0. Note that all three tests fail on FreeBSD, which defines all mutex type values, as well as all C11 threads error codes with non-0 values.

* Change most internal uses of __gettimeofday to __clock_gettime.Zack Weinberg2019-10-302-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since gettimeofday will shortly be implemented in terms of clock_gettime on all platforms, internal code should use clock_gettime directly; in addition to removing a layer of indirection, this will allow us to remove the PLT-bypass gunk for gettimeofday. (We can't quite do that yet, but it'll be coming later in this patch series.) In many cases, the changed code does fewer conversions. The changed code always assumes __clock_gettime (CLOCK_REALTIME) cannot fail. Most of the call sites were assuming gettimeofday could not fail, but a few places were checking for errors. POSIX says clock_gettime can only fail if the clock constant is invalid or unsupported, and CLOCK_REALTIME is the one and only clock constant that's required to be supported. For consistency I grepped the entire source tree for any other places that checked for errors from __clock_gettime (CLOCK_REALTIME), found one, and changed it too. (For the record, POSIX also says gettimeofday can never fail.) (It would be nice if we could declare that GNU systems will always support CLOCK_MONOTONIC as well as CLOCK_REALTIME; there are several places where we are using CLOCK_REALTIME where _MONOTONIC would be more appropriate, and/or trying to use _MONOTONIC and then falling back to _REALTIME. But the Hurd doesn't support CLOCK_MONOTONIC yet, and it looks like adding it would involve substantial changes to gnumach's internals and API. Oh well.) A few Hurd-specific files were changed to use __host_get_time instead of __clock_gettime, as this seemed tidier. We also assume this cannot fail. Skimming the code in gnumach leads me to believe the only way it could fail is if __mach_host_self also failed, and our Hurd-specific code consistently assumes that can't happen, so I'm going with that. With the exception of support/support_test_main.c, test cases are not modified, mainly because I didn't want to have to figure out which test cases were testing gettimeofday specifically. The definition of GETTIME in sysdeps/generic/memusage.h had a typo and was not reading tv_sec at all. I fixed this. It appears nobody has been generating malloc traces on a machine that doesn't have a superseding definition. There are a whole bunch of places where the code could be simplified by factoring out timespec subtraction and/or comparison logic, but I want to keep this patch as mechanical as possible. Checked on x86_64-linux-gnu, i686-linux-gnu, powerpc64le-linux-gnu, powerpc64-linux-gnu, powerpc-linux-gnu, and aarch64-linux-gnu.

* time: Introduce function to check correctness of nanoseconds valueLukasz Majewski2019-10-271-4/+2
| | | | | | | | | | | | | | | The valid_nanoseconds () static inline function has been introduced to check if nanoseconds value is in the correct range - greater or equal to zero and less than 1000000000. The explicit #include <time.h> has been added to files where it was missing. The __syscall_slong_t type for ns has been used to avoid issues on x32. Tested with: - scripts/build-many-glibcs.py - make PARALLELMFLAGS="-j12" && make PARALLELMFLAGS="-j12" xcheck on x86_64
