/* The netlink messages for the audit system is divided into blocks:

* 1000 - 1099 are for commanding the audit system

* 1100 - 1199 user space trusted application messages

* 1200 - 1299 messages internal to the audit daemon

* 1300 - 1399 audit event messages

* 1400 - 1499 SE Linux use

* 1500 - 1599 kernel LSPP events

* 1600 - 1699 kernel crypto events

* 1700 - 1799 kernel anomaly records

* 1800 - 1899 kernel integrity events

* 1900 - 1999 future kernel use

* 2000 is for otherwise unclassified kernel audit messages (legacy)

* 2001 - 2099 unused (kernel)

* 2100 - 2199 user space anomaly records

* 2200 - 2299 user space actions taken in response to anomalies

* 2300 - 2399 user space generated LSPP events

* 2400 - 2499 user space crypto events

* 2500 - 2999 future user space (maybe integrity labels and related events)

*

* Messages from 1000-1199 are bi-directional. 1200-1299 & 2100 - 2999 are

* exclusively user space. 1300-2099 is kernel --> user space

* communication.
