* Remove "Contributed by" linesSiddhesh Poyarekar2021-09-031-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | We stopped adding "Contributed by" or similar lines in sources in 2012 in favour of git logs and keeping the Contributors section of the glibc manual up to date. Removing these lines makes the license header a bit more consistent across files and also removes the possibility of error in attribution when license blocks or files are copied across since the contributed-by lines don't actually reflect reality in those cases. Move all "Contributed by" and similar lines (Written by, Test by, etc.) into a new file CONTRIBUTED-BY to retain record of these contributions. These contributors are also mentioned in manual/contrib.texi, so we just maintain this additional record as a courtesy to the earlier developers. The following scripts were used to filter a list of files to edit in place and to clean up the CONTRIBUTED-BY file respectively. These were not added to the glibc sources because they're not expected to be of any use in future given that this is a one time task: https://gist.github.com/siddhesh/b5ecac94eabfd72ed2916d6d8157e7dc https://gist.github.com/siddhesh/15ea1f5e435ace9774f485030695ee02 Reviewed-by: Carlos O'Donell <carlos@redhat.com>
* y2038: Add support for 64-bit time on legacy ABIsAdhemerval Zanella2021-06-151-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A new build flag, _TIME_BITS, enables the usage of the newer 64-bit time symbols for legacy ABI (where 32-bit time_t is default). The 64 bit time support is only enabled if LFS (_FILE_OFFSET_BITS=64) is also used. Different than LFS support, the y2038 symbols are added only for the required ABIs (armhf, csky, hppa, i386, m68k, microblaze, mips32, mips64-n32, nios2, powerpc32, sparc32, s390-32, and sh). The ABIs with 64-bit time support are unchanged, both for symbol and types redirection. On Linux the full 64-bit time support requires a minimum of kernel version v5.1. Otherwise, the 32-bit fallbacks are used and might results in error with overflow return code (EOVERFLOW). The i686-gnu does not yet support 64-bit time. This patch exports following rediretions to support 64-bit time: * libc: adjtime adjtimex clock_adjtime clock_getres clock_gettime clock_nanosleep clock_settime cnd_timedwait ctime ctime_r difftime fstat fstatat futimens futimes futimesat getitimer getrusage gettimeofday gmtime gmtime_r localtime localtime_r lstat_time lutimes mktime msgctl mtx_timedlock nanosleep nanosleep ntp_gettime ntp_gettimex ppoll pselec pselect pthread_clockjoin_np pthread_cond_clockwait pthread_cond_timedwait pthread_mutex_clocklock pthread_mutex_timedlock pthread_rwlock_clockrdlock pthread_rwlock_clockwrlock pthread_rwlock_timedrdlock pthread_rwlock_timedwrlock pthread_timedjoin_np recvmmsg sched_rr_get_interval select sem_clockwait semctl semtimedop sem_timedwait setitimer settimeofday shmctl sigtimedwait stat thrd_sleep time timegm timerfd_gettime timerfd_settime timespec_get utime utimensat utimes utimes wait3 wait4 * librt: aio_suspend mq_timedreceive mq_timedsend timer_gettime timer_settime * libanl: gai_suspend Reviewed-by: Lukasz Majewski <lukma@denx.de> Reviewed-by: Carlos O'Donell <carlos@redhat.com> Tested-by: Carlos O'Donell <carlos@redhat.com>

* y2038: nptl: Convert pthread_rwlock_{clock|timed}{rd|wr}lock to support 64 ↵Lukasz Majewski2020-10-041-3/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | bit time The pthread_rwlock_clockrdlock, pthread_rwlock_clockwrlock, pthread_rwlock_timedrdlock and pthread_rwlock_timedwrlock have been converted to support 64 bit time. This change uses new futex_abstimed_wait64 function in ./sysdeps/nptl/futex-helpers.c, which uses futex_time64 where possible. The pthread_rwlock_{clock|timed}{rd|wr}lock only accepts absolute time. Moreover, there is no need to check for NULL passed as *abstime pointer to the syscalls as those calls have exported symbols marked with __nonull attribute for abstime. For systems with __TIMESIZE != 64 && __WORDSIZE == 32: - Conversions between 64 bit time to 32 bit are necessary - Redirection to pthread_rwlock_{clock|timed}{rd|wr}lock will provide support for 64 bit time Build tests: ./src/scripts/build-many-glibcs.py glibcs Run-time tests: - Run specific tests on ARM/x86 32bit systems (qemu): https://github.com/lmajewski/meta-y2038 and run tests: https://github.com/lmajewski/y2038-tests/commits/master Above tests were performed with Y2038 redirection applied as well as without to test the proper usage of both __pthread_rwlock_{clock|timed}{rd|wr}lock64 and __pthread_rwlock_{clock|timed}{rd|wr}lock.

* Add and use new glibc-internal futex API.Torvald Riegel2015-07-101-47/+10
| | | | | | | | | | | | | | | | | | | | This adds new functions for futex operations, starting with wait, abstimed_wait, reltimed_wait, wake. They add documentation and error checking according to the current draft of the Linux kernel futex manpage. Waiting with absolute or relative timeouts is split into separate functions. This allows for removing a few cases of code duplication in pthreads code, which uses absolute timeouts; also, it allows us to put platform-specific code to go from an absolute to a relative timeout into the platform-specific futex abstractions.. Futex operations that can be canceled are also split out into separate functions suffixed by "_cancelable". There are separate versions for both Linux and NaCl; while they currently differ only slightly, my expectation is that the separate versions of lowlevellock-futex.h will eventually be merged into futex-internal.h when we get to move the lll_ functions over to the new futex API.
* Fix missing wake-ups in pthread_rwlock_rdlock.Torvald Riegel2015-06-041-0/+17
| | | | | | | | | This adds wake-ups that would be missing if assuming that for a non-writer-preferring rwlock, if one thread has acquired a rdlock and does not release it, another thread will eventually acquire a rdlock too despite concurrent write lock acquisition attempts. BZ 14958 is about supporting this assumption. Strictly speaking, this isn't a valid test case, but nonetheless worth supporting (see comment 7 of BZ 14958).

* Fix pthreads getrlimit, gettimeofday namespace (bug 17682).Joseph Myers2014-12-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some pthreads functions use getrlimit and gettimeofday, but these functions are XSI, not base POSIX; this is a namespace issue for dynamic linking as well as static linking. This patch makes them use __getrlimit and __gettimeofday instead - the former needed to be newly exported from libc.so at GLIBC_PRIVATE (and so now needs libc_hidden_proto / libc_hidden_def), the latter was already exported. Tested for x86_64 (testsuite, and that disassembly of installed shared libraries is unchanged by the patch).

* Include <kernel-features.h> explicitly where required.Joseph Myers2014-06-201-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes files using __ASSUME_* macros include <kernel-features.h> explicitly, rather than relying on some other header (such as tls.h, lowlevellock.h or pthreadP.h) to include it implicitly. (I omitted cases where I've already posted or am testing the patch that stops the file from needing __ASSUME_* at all.) This accords with the general principle of making source files include the headers for anything they use, and also helps make it safe to remove <kernel-features.h> includes from any file that doesn't use __ASSUME_* (some of those may be stray includes left behind after increasing the minimum kernel version, others may never have been needed or may have become obsolete after some other change).

* [S390,PPC] Implement FUTEX_WAIT_BITSET for timedwait functionsSiddhesh Poyarekar2012-11-051-1/+20
| | | | | | | | | | | | | | Since the FUTEX_WAIT operation takes a relative timeout, the pthread_cond_timedwait and other timed function implementations have to get a relative timeout from the absolute timeout parameter it gets before it makes the futex syscall. This value is then converted back into an absolute timeout within the kernel. This is a waste and has hence been improved upon by a FUTEX_WAIT_BITSET operation (OR'd with FUTEX_CLOCK_REALTIME to make the kernel use the realtime clock instead of the default monotonic clock). This was implemented only in the x86 and sh assembly code and not in the C code. This patch implements support for FUTEX_WAIT_BITSET whenever available (since linux-2.6.29) for s390 and powerpc.
