Hello Steve, 

Thanks for your detailed explanation.
But I found two cases for "CONFIG_CHANGE" message miss "key" field.

for example1:
1. # touch temp_file
2. # auditctl -w `pwd`/temp_file -k temp_file
3. # rm -f temp_file
The "CONFIG_CHANGE" message is "type=CONFIG_CHANGE msg=audit(1217667917.265:1027): op=updated rules specifying path="/root/temp_file" with dev=4294967295 ino=4294967295  list=0 res=1".

for example2:
1. # auditctl -e 2
2. # auditctl -a exit,always -S open -k temp_file
The "CONFIG_CHANGE" message is "type=CONFIG_CHANGE msg=audit(1217668048.831:1031): user pid=13202 uid=0 auid=0 ses=1 subj=root:system_r:auditctl_t:s0-s0:c0.c1023 audit_enabled=2 res=0".

Are they OK or error?
