The AUDIT_INTEGRITY_RULE is used for auditing IMA policy rules and the IMA "audit" policy action. This patch defines AUDIT_INTEGRITY_POLICY_RULE to reflect the IMA policy rules.
With this change we now call integrity_audit_msg_common() to get common integrity auditing fields. This now produces the following record when parsing an IMA policy rule: type=UNKNOWN[1806] msg=audit(1527004216.690:311): action=dont_measure \ fsmagic=0x9fa0 pid=1613 uid=0 auid=0 ses=2 \ subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 \ op=policy_update cause=parse_rule comm="echo" exe="/usr/bin/echo" \ tty=tty2 res=1 Signed-off-by: Stefan Berger <[email protected]> --- include/uapi/linux/audit.h | 3 ++- security/integrity/ima/ima_policy.c | 5 +++-- 2 files changed, 5 insertions(+), 3 deletions(-) diff --git a/include/uapi/linux/audit.h b/include/uapi/linux/audit.h index 4e61a9e05132..776e0abd35cf 100644 --- a/include/uapi/linux/audit.h +++ b/include/uapi/linux/audit.h @@ -146,7 +146,8 @@ #define AUDIT_INTEGRITY_STATUS 1802 /* Integrity enable status */ #define AUDIT_INTEGRITY_HASH 1803 /* Integrity HASH type */ #define AUDIT_INTEGRITY_PCR 1804 /* PCR invalidation msgs */ -#define AUDIT_INTEGRITY_RULE 1805 /* policy rule */ +#define AUDIT_INTEGRITY_RULE 1805 /* IMA "audit" action policy msgs */ +#define AUDIT_INTEGRITY_POLICY_RULE 1806 /* IMA policy rules */ #define AUDIT_KERNEL 2000 /* Asynchronous audit record.
