[PATCH] Exclude messages by message type
- Add a new, 5th filter called "exclude".
- And add a new field AUDIT_MSGTYPE.
- Define a new function audit_filter_exclude() that takes a message type
as input and examines all rules in the filter. It returns '1' if the
message is to be excluded, and '0' otherwise.
- Call the audit_filter_exclude() function near the top of
audit_log_start() just after asserting audit_initialized. If the
message type is not to be audited, return NULL very early, before
doing a lot of work.
[combined with followup fix for bug in original patch, Nov 4, same author]
[combined with later renaming AUDIT_FILTER_EXCLUDE->AUDIT_FILTER_TYPE
and audit_filter_exclude() -> audit_filter_type()]
