Comment 13 for bug 1964636

I can easily reproduce with stgraber's instructions on an arm64 VM running 20.04 with the 5.4 kernel.

Maciej asked me to provide the output of the following commands:

in the LXD container:

root@c1:~# echo 'profile snap-test { capability bpf, }' | apparmor_parser --preprocess ; echo $?
Warning from stdin (line 1): apparmor_parser: Warning capping number of jobs to 0 * # of cpus == '16'AppArmor parser error, in stdin line 1: Invalid capability bpf.
0

on the host:

ubuntu@anbox-streaming-stack-0:~$ echo 'profile snap-test { capability bpf, }' | apparmor_parser --preprocess ; echo $?
AppArmor parser error, in stdin line 1: Invalid capability bpf.
profile snap-test { capability bpf1
