To summarize, we need to disambiguate the 1805, as both
ima_parse_rule() and ima_audit_measurement() are using the same number
with different formats. The main usage of 1805 that we are aware of
is ima_audit_measurement(). Yet the "type=" name for
ima_audit_measurement() should be INTEGRITY_IMA_AUDIT, not
INTEGRITY_RULE.
option 1: breaks both uses
1805 - INTEGRITY_IMA_AUDIT - ima_audit_measurement()
1806 - INTEGRITY_POLICY_RULE - ima_parse_rule()
option 2: breaks the most common usage
1805 - INTEGRITY_RULE - ima_parse_rule()
1806 - INTEGRITY_IMA_AUDIT - ima_audit_measurement()
option 3: leaves the most common usage with the wrong name, and breaks
the other less common usage
1805 - INTEGRITY_RULE - ima_audit_measurement()
1806 - INTEGRITY_POLICY_RULE - ima_parse_rule()
So option 3 is the best option?
Mimi
