Hello! The kernel team has applied the fix to their pre-release branch.
They have a 5-week release cycle, so we should be seeing a new Bionic

It seems the s390x failure on bionic is fixed by the patch(es) for bug
1895132. I'm not 100% sure why it is returning the normal ENOSYS for
invalid syscalls except while running under systemd-nspawn, but it might
be due to the different syscall entry path taken when _TIF_TRACE is set,
and that
Interestingly, faccessat2() does correctly return ENOSYS when using a
simple chroot instead of systemd-nspawn:
ubuntu@test-s390x:~/h$ sudo systemd-nspawn
Spawning container h on /home/ubuntu/h.

libseccomp and the inability to easily handle and distinguish newly
added syscalls between
To paper over the faccessat2 issue, a libseccomp update is enough *if*
the container runtime already knows about the faccessat2 system call and
mentions it in its profiles. But with the current design, every new
system call will need similar updates to several components (not just
libseccomp) just
I've been scratching my head over this regression [1] for a while now,

after upgrading glibc, `which` is broken; that of course also uses
