And I've just closed it since the associated SYSCALL setsockopt record
lists all that information.
AUDIT_NETFILTER_CFG sometimes comes out of the kernel with no syscall record.
Try this,
ausearch --start today -m netfilter_cfg | less
You should see at least one that has no syscall record. This begs the question
of why there is even a SYSCALL record? AUDIT_NETFILTER_CFG is not extra
information that is gathered to help explain what the syscall means. Its a
change to system configuration in its own right. It should not be attached to a
syscall record - especially if its not consistent. It should be complete and
stand on its own.
