[SRU Xenial 0/1] CVE-2021-29154

[Thadeu Lima de Souza Cascardo]

[Impact]

See https://www.openwall.com/lists/oss-security/2021/04/08/1.

[Test case]

Ran LTP bpf tests and test_kmod.sh from kselftests, that use the test_bpf
module.

[Regression potential]

Some BPF code might fail to load and this might prevent seccomp, systemd, etc,
from correctly running services, so boot may fail and safeguards might not run.
