You have to consider the lists that they are on. Each list is evaluated from
first to last. Any event that is created is sent to the exclude filter for
potential action.
Examples:
entry,always -S chmod - should see a record for chmod
exclude,always -S all - should never see any sys calls
Combined, should I expect a chmod record?
Yes. The exclude filter only removes records by message type.
exclude,always -F msgtype=SYSCALL
would be a valid use of it.
From my experiments with the current code, if any one rule
instructs
audit to log the action, auditd will log it (i.e. I'll see a chmod
record). I'm wondering if this is the intended functionality.
I suspect we should have an error when you try to load a rule like in you
example.
