[PATCH ghak25 v2 7/9] netfilter: ebtables audit table registration

From: Richard Guy Briggs
Date: Mon Jan 06 2020 - 13:56:19 EST


Generate audit NETFILTER_CFG records on ebtables table registration.

Previously this was only being done for all x_tables operations and
ebtables table replacement.

Call new audit_nf_cfg() to store table parameters for later use with
syscall records.

Here is a sample accompanied record:
type=NETFILTER_CFG msg=audit(1494907217.558:5403): table=filter family=7 entries=0
