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. Since we defined a new message type we can now also call audit_log_task_info() for task specific fields. This now produces the following record when parsing an IMA policy rule: type=UNKNOWN[1807] msg=audit(1527722337.757:338): action=audit \ func=BPRM_CHECK mask=MAY_EXEC ppid=1613 pid=1657 auid=0 uid=0 \ gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=tty4 ses=4 \ comm="echo" exe="/usr/bin/echo" \ subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 res=1 Signed-off-by: Stefan Berger <stefanb@linux.vnet.ibm.com> --- include/uapi/linux/audit.h | 1 + security/integrity/ima/ima_policy.c | 12 +++++++++--- 2 files changed, 10 insertions(+), 3 deletions(-)
