[PATCH 0/2] audit: log binding and unbinding to netlink multicast socket

[Steve Grubb]

Hello,

I am resurrecting this old patch. Its been cleaned up by adding a simple task 
logging function which should, in the future, serve almost all kernel logging 
needs. The cleaned up bind and unbind functions call it to create the preamble 
and then finish with specific data items for bind/unbinding.

In essence, this patch logs connecting and disconnecting to the audit netlink 
multicast socket. This is needed so that during investigations a security 
officer can tell who or what had access to the audit trail. This helps to meet 
the FAU_SAR.2 SFR for Common Criteria.

Sample output:
type=UNKNOWN[1330] audit(1480532106.644:2): pid=1 uid=0 auid=4294967295 
tty=(none) ses=4294967295 subj=kernel comm="systemd" exe="/usr/lib/systemd/
systemd" nlnk-grp=1 op=connect res=1
