2021-03-23tst: Provide test for selectLukasz Majewski
This change adds new test to assess select()'s timeout related functionality (the rdfs set provides valid fd - stderr - but during normal program operation there is no data to be read, so one just waits for timeout). To be more specific - two use cases are checked: - if select() times out immediately when passed struct timeval has zero values of tv_usec and tv_sec. - if select() times out after timeout specified in passed argument Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>

2021-03-15Build libc-start with stack protector for SHAREDSiddhesh Poyarekar
This does not change the emitted code since __libc_start_main does not return, but is important for formal flags compliance. This also cleans up the cosmetic inconsistency in the stack protector flags in csu, especially the incorrect value of STACK_PROTECTOR_LEVEL.

2021-03-15Build get-cpuid-feature-leaf.c without stack-protector [BZ #27555]Siddhesh Poyarekar
__x86_get_cpuid_feature_leaf is called during early startup, before the stack check guard is initialized and is hence not safe to build with stack-protector. Additionally, IFUNC resolvers for static tst-ifunc-isa tests get called too early for stack protector to be useful, so fix them to disable stack protector for the resolver functions. This fixes all failures seen with --enable-stack-protector=all configuration. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>

2021-03-15elf: ld.so --help calls _dl_init_paths without a main map [BZ #27577]Florian Weimer
In this case, use the link map of the dynamic loader itself as a replacement. This is more than just a hack: if we ever support DT_RUNPATH/DT_RPATH for the dynamic loader, reporting it for ld.so --help (without further command line arguments) would be the right thing to do. Fixes commit 332421312576bd7095e70589154af99b124dd2d1 ("elf: Always set l in _dl_init_paths (bug 23462)").

2021-03-12elf: Always set l in _dl_init_paths (bug 23462)Carlos O'Donell
After d1d5471579eb0426671bf94f2d71e61dfb204c30 ("Remove dead DL_DST_REQ_STATIC code.") we always setup the link map l to make the static and shared cases the same. The bug is that in elf/dl-load.c (_dl_init_paths) we conditionally set l only in the #ifdef SHARED case, but unconditionally use it later. The simple solution is to remove the #ifdef SHARED conditional, because it's no longer needed, and unconditionally setup l for both the static and shared cases. A regression test is added to run a static binary with LD_LIBRARY_PATH='$ORIGIN' which crashes before the fix and runs after the fix. Co-Authored-By: Florian Weimer <fweimer@redhat.com>

Both htl and nptl uses a different data structure to implement atfork handlers. The nptl one was refactored by 27761a1042d to use a dynarray which simplifies the code. This patch moves the nptl one to be the generic implementation and replace Hurd linked one. Different than previous NPTL, Hurd also uses a global lock, so performance should be similar. Checked on x86_64-linux-gnu, i686-linux-gnu, and with a build for i686-gnu.

2021-03-12io: Return UNSUPPORTED if filesystem do not support 64 bit timestampsAdhemerval Zanella
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
2021-03-11test-container: Always copy test-specific support files [BZ #27537]DJ Delorie
There's a small chance that a fresh checkout will result in some of the test-specific container files will have the same timestamp and size, which breaks the rsync logic in test-container, resulting in tests running with the wrong support files. This patch changes the rsync logic to always copy the test-specific files, which normally would always be copied anyway. The rsync logic for the testroot itself is unchanged.
