[GIT PULL] Audit patches for v5.8

[Paul Moore <paul@paul-moore.com>]

Hi Linus,

Here is the set of audit patches for the v5.8 merge window, all
patches pass our test suite and as of a few minutes ago they also
merge cleanly with the top of your tree.  Unfortunately I just noticed
that one of the commit subject lines is truncated - sorry about that,
it's my fault not Richard's - but since the important part is there
("add subj creds to NETFILTER_CFG") I opted to leave it as-is and not
disrupt the git log.  If you would rather have the subject line fixed,
let me know and I'll correct it.

A quick summary of the significant patches:

- Record information about binds/unbinds to the audit multicast
socket.  This helps identify which processes have/had access to the
information in the audit stream.

- Cleanup and add some additional information to the netfilter
configuration events collected by audit.

- Fix some of the audit error handling code so we don't leak network
namespace references.

Thanks,
-Paul
