2022-02-18glibc: fix create thread failed in unprivileged processHongxu Jia
Since upstream commit [d8ea0d0168 Add an internal wrapper for clone, clone2 and clone3] applied, start a unprivileged container (docker run without --privileged), it creates a thread failed in container. In commit d8ea0d0168, it calls __clone3 if HAVE_CLONE3_WAPPER is defined. If __clone3 returns -1 with ENOSYS, fall back to clone or clone2. As known from [1], cloneXXX fails with EPERM if CLONE_NEWCGROUP, CLONE_NEWIPC, CLONE_NEWNET, CLONE_NEWNS, CLONE_NEWPID, or CLONE_NEWUTS was specified by an unprivileged process (process without CAP_SYS_ADMIN) [1] https://man7.org/linux/man-pages/man2/clone3.2.html So if __clone3 returns -1 with EPERM, fall back to clone or clone2 could fix the issue.

OpenEmbedded isn't an upstream or a patch repository. These are optimisations which for reasons unknown were never merged into upstream glibc.

2021-11-23glibc: ptest: Add running glibc time related test suite (Y2038) with ptestLukasz Majewski
This patch introduces new recipe - namely 'glibc-tests', which builds and installs time related (to check if Y2038 support works) glibc test suite to OE/Yocto built image. It reuses code from already available 'glibc-testsuite' recipe, which is run with 'bitbake glibc-testsuite -c check' and uses qemu to execute remotely (via SSH) tests on some emulated machine. This recipe installs time related glibc tests on some rootfs image. Afterwards, those tests can be executed on the real hardware, to facilitate validation of it with Y2038 problem compliance. To test time related subset - one needs to call: ptest-runner glibc-tests then change the date after Y2038 threshold for 32 bit systems: date -s "20 JAN 2038 18:00:00" and then run ptest-runner again. To facilitate debugging, source files are provided by default with the unstripped debugging symbols. Such approach would reduce the already complex recipe (as it inherits base glibc one), so there is no need to also install *-dbg and *-src packages.

2021-11-10meta: use ln -rs instead of lnrRoss Burton
lnr is a script in oe-core that creates relative symlinks, with the same behaviour as `ln --relative --symlink`. It was added back in 2014[1] as not all of the supported host distributions at the time shipped coreutils 8.16, the first release with --relative. However the oldest coreutils release in the supported distributions is now 8.22 in CentOS 7, so lnr can be deprecated and users switched to ln.

2021-05-20glibc: Add 8GB VM usage cap for usermode test suiteRichard Purdie
We've noticed that: MACHINE=qemuarm oe-selftest -r glibc.GlibcSelfTest.test_glibc ends up with one process growing to about the size of system memory and triggering the OOM killer. This has been taking out other builds running on the system on the autobuilders and is one cause of our intermittent failures. This was tracked down to: WORKDIR=XXX/tmp/work/armv7vet2hf-neon-poky-linux-gnueabi/glibc-testsuite/2.33-r0 BUILDDIR=$WORKDIR/build-arm-poky-linux-gnueabi QEMU_SYSROOT=$WORKDIR/recipe-sysroot QEMU_OPTIONS="$WORKDIR/recipe-sysroot-native/usr/bin/qemu-arm -r 3.2.0" \ $WORKDIR/check-test-wrapper user env GCONV_PATH=$BUILDDIR/iconvdata LOCPATH=$BUILDDIR/localedata LC_ALL=C $BUILDDIR/elf/ld-linux-armhf.so.3 \ --library-path $BUILDDIR:$BUILDDIR/math:$BUILDDIR/elf:$BUILDDIR/dlfcn:$BUILDDIR/nss:$BUILDDIR/nis:$BUILDDIR/rt:$BUILDDIR/resolv:$BUILDDIR/mathvec:$BUILDDIR/support:$BUILDDIR/nptl \ $BUILDDIR/nptl/tst-pthread-timedlock-lockloop although other glibc tests appear to use 16GB of memory before failing anyway. By capping the VM size to 8GB, we see the same number of failures but no OOM situations. There may be some issue in qemu or the test which could be improved to avoid this entirely but this provides a necessary and useful safeguard to other builds and doensn't appear to make the situation worse. On a loaded system OOM may not occur as the test timeout may be triggered first. An experiment with a 5GB limit showed an additional 7 failures.
