* nptl: Move pthread_getspecific, __pthread_getspecific into libcFlorian Weimer2021-03-1861-58/+128

* nptl: Move part of TCB initialization from libpthread to __tls_init_tpFlorian Weimer2021-03-181-29/+0
| | | | | | | | | | | | | | | | | This initalization should only happen once for the main thread's TCB. At present, auditors can achieve this by not linking against libpthread. If libpthread becomes part of libc, doing this initialization in libc would happen for every audit namespace, or too late (if it happens from the main libc only). That's why moving this code into ld.so seems the right thing to do, right after the TCB initialization. For !__ASSUME_SET_ROBUST_LIST ports, this also moves the symbol __set_robust_list_avail into ld.so, as __nptl_set_robust_list_avail. It also turned into a proper boolean flag. Inline the __pthread_initialize_pids function because it seems no longer useful as a separate function.
* nptl: Move pthread_setcanceltype into libcFlorian Weimer2021-03-1829-29/+0
| | | | | | | | No new symbol version is required because there was a forwarder. The symbol has been moved using scripts/move-symbol-to-libc.py. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>

* nptl: Move pthread_exit into libcFlorian Weimer2021-03-1829-29/+0
| | | | | | | | | | | | | | The pthread_exit symbol was moved using scripts/move-symbol-to-libc.py. No new symbol version is needed because there was a forwarder. The new tests nptl/tst-pthread_exit-nothreads and nptl/tst-pthread_exit-nothreads-static exercise the scenario that pthread_exit is called without libpthread having been linked in. This is not possible for the generic code, so these tests do not live in sysdeps/pthread for now. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
* nptl: Move __pthread_unwind_next into libcFlorian Weimer2021-03-1863-56/+65
| | | | | | | | | | | | | | | | | | | It's necessary to stub out __libc_disable_asynccancel and __libc_enable_asynccancel via rtld-stubbed-symbols because the new direct references to the unwinder result in symbol conflicts when the rtld exception handling from libc is linked in during the construction of librtld.map. unwind-forcedunwind.c is merged into unwind-resume.c. libc now needs the functions that were previously only used in libpthread. The GLIBC_PRIVATE exports of __libc_longjmp and __libc_siglongjmp are no longer needed, so switch them to hidden symbols. The symbol __pthread_unwind_next has been moved using scripts/move-symbol-to-libc.py. Reviewed-by: Adhemerva Zanella <adhemerval.zanella@linaro.org>
* nptl: Move pthread_once and __pthread_once into libcFlorian Weimer2021-03-1861-58/+128
| | | | | | | | | | | And also the fork generation counter, __fork_generation. This eliminates the need for __fork_generation_pointer. call_once remains in libpthread and calls the exported __pthread_once symbol. pthread_once and __pthread_once have been moved using scripts/move-symbol-to-libc.py.
* nptl: Move __pthread_cleanup_upto into libcFlorian Weimer2021-03-181-5/+2
| | | | | | | | This internal symbol is used as part of the longjmp implementation. Rename the file from nptl/pt-cleanup.c to nptl/pthread_cleanup_upto.c so that the pt-* files remain restricted to libpthread. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>

* nptl: Remove longjmp, siglongjmp from libpthreadFlorian Weimer2021-03-1829-153/+28
| | | | | | | | | | | | | | The definitions in libc are sufficient, the forwarders are no longer needed. The symbols have been moved using scripts/move-symbol-to-libc.py. s390-linux-gnu and s390x-linux-gnu need a new version placeholder to keep the GLIBC_2.19 symbol version in libpthread.

* nptl: Move legacy cancelation handling into libc as compat symbolsFlorian Weimer2021-03-1861-116/+128
| | | | | | | | | | | | | | | This affects _pthread_cleanup_pop, _pthread_cleanup_pop_restore, _pthread_cleanup_push, _pthread_cleanup_push_defer. The symbols have been moved using scripts/move-symbol-to-libc.py. No new symbol versions are added because the symbols are turned into compatibility symbols at the same time. __pthread_cleanup_pop and __pthread_cleanup_push are added as GLIBC_PRIVATE symbols because they are also used internally, for glibc's own cancellation handling.

* io: Return UNSUPPORTED if filesystem do not support 64 bit timestampsAdhemerval Zanella2021-03-123-3/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some Linux filesystems might not fully support 64 bit timestamps [1], which make some Linux specific tests to fail when they check for the functionality. This patch adds a new libsupport function, support_path_support_time64, that returns whether the target file supports or not 64 bit timestamps. The support is checked by issuing a utimensat and verifying both the last access and last modification time against a statx call. The tests that might fail are also adjusted to check the file support as well: $ dd if=/dev/zero of=loopbackfile.img bs=100M count=1 1+0 records in 1+0 records out 104857600 bytes (105 MB, 100 MiB) copied, 0,0589568 s, 1,8 GB/s $ sudo losetup -fP loopbackfile.img $ mkfs.xfs loopbackfile.img meta-data=loopbackfile.img isize=512 agcount=4, agsize=6400 blks = sectsz=512 attr=2, projid32bit=1 = crc=1 finobt=1, sparse=1, rmapbt=0 = reflink=1 data = bsize=4096 blocks=25600, imaxpct=25 = sunit=0 swidth=0 blks naming =version 2 bsize=4096 ascii-ci=0, ftype=1 log =internal log bsize=4096 blocks=1368, version=2 = sectsz=512 sunit=0 blks, lazy-count=1 realtime =none extsz=4096 blocks=0, rtextents=0 $ mkdir loopfs $ sudo mount -o loop /dev/loop0 loopfs/ $ sudo chown -R azanella:azanella loopfs $ TMPDIR=loopfs/ ./testrun.sh misc/tst-utimes error: ../sysdeps/unix/sysv/linux/tst-utimes.c:55: File loopfs//utimesfECsK1 does not support 64-bit timestamps [1] https://bugzilla.redhat.com/show_bug.cgi?id=1795576

* tst: Fix tst-timerfd testLukasz Majewski2021-03-021-11/+4
| | | | | | | | | | | | | | | | | | | There were following problems discovered for tst-timerfd test: 1. Do not set the struct itimerspec's it_interval tv_sec to 2 seconds. After this change the timerfd will trigger only once (the it_value is only set in this case). 2. The 'val1' variable (including the call to timerfd_gettime) is not needed anymore, as it is just enough to read the struct itimerspec after sleep. As a consequence the 'val2' has been renamed to 'val'. 3. After calling timerfd_gettime, the value of struct itimerspec time, when timer is running, is the remaining time. In the case of this test it would be less than 1 second. As a result the TEST_COMPARE macro logic had to be adjusted. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
