30/* The netlink messages for the audit system is divided into blocks:
31 * 1000 - 1099 are for commanding the audit system
32 * 1100 - 1199 user space trusted application messages
33 * 1200 - 1299 messages internal to the audit daemon
34 * 1300 - 1399 audit event messages
35 * 1400 - 1499 SE Linux use
36 * 1500 - 1599 kernel LSPP events
37 * 1600 - 1699 kernel crypto events
38 * 1700 - 1799 kernel anomaly records
39 * 1800 - 1999 future kernel use (maybe integrity labels and related events)
40 * 2000 is for otherwise unclassified kernel audit messages (legacy)
41 * 2001 - 2099 unused (kernel)
42 * 2100 - 2199 user space anomaly records
43 * 2200 - 2299 user space actions taken in response to anomalies
44 * 2300 - 2399 user space generated LSPP events
45 * 2400 - 2499 user space crypto events
46 * 2500 - 2999 future user space (maybe integrity labels and related events)
47 *
48 * Messages from 1000-1199 are bi-directional. 1200-1299 & 2100 - 2999 are
49 * exclusively user space. 1300-2099 is kernel --> user space
50 * communication.
