Bug#911384: Attaching egress BPF program to cgroup: Invalid argument

[Helge Kreutzmann]

Package: systemd
Version: 239-10
Severity: normal

After upgrading to a a 4.18 kernel (not Debian, self compiled) I get
several
Attaching egress BPF program to cgroup /sys/fs/cgroup/unified/system.slice/systemd-*.service failed: Invalid argument

where * is one of login, journald, udevd, hostnamed.

I do not see a pattern, which of the above are logged after which
system boot.

I read [1] and [2] which said it should be fixed (it dit not occur
under a 4.17 kernel).
