    audit: add subj creds to NETFILTER_CFG record to · 9d44a121

    Some table unregister actions seem to be initiated by the kernel to
    garbage collect unused tables that are not initiated by any userspace
    actions.  It was found to be necessary to add the subject credentials to
    cover this case to reveal the source of these actions.  A sample record:
    
    The uid, auid, tty, ses and exe fields have not been included since they
    are in the SYSCALL record and contain nothing useful in the non-user
    context.
    
    Here are two sample orphaned records:
    
      type=NETFILTER_CFG msg=audit(2020-05-20 12:14:36.505:5) : table=filter family=ipv4 entries=0 op=register pid=1 subj=kernel comm=swapper/0
    
      type=NETFILTER_CFG msg=audit(2020-05-20 12:15:27.701:301) : table=nat family=bridge entries=0 op=unregister pid=30 subj=system_u:system_r:kernel_t:s0 comm=kworker/u4:1
