Subject: result logged in integrity audit message
Date: Fri, 5 Jun 2020 20:13:56 -0700 [thread overview]
Message-ID: <4c41ce1e-3f97-5b14-8152-5411a3debb57@linux.microsoft.com> (raw)
Hi Mimi,
In integrity audit message function the inverse of "result" is being
logged for "res=". Please see below. Is this intentional?
void integrity_audit_msg(int audit_msgno, struct inode *inode,
const unsigned char *fname, const char *op,
const char *cause, int result, int audit_info)
{
...
audit_log_format(ab, " res=%d", !result);
}
The callers of this function are passing an error code (-ENOMEM,
-EINVAL, etc.) in the "result" parameter. But that error code is lost -
instead "res" is set to 0.
For example,
audit: type=1804 audit(1591411737.631:3): pid=1 uid=0 auid=4294967295
ses=4294967295 subj=kernel op=ima_alloc_key_entry cause=ENOMEM
comm="swapper/0" name=".builtin_trusted_keys" res=0
thanks,
-lakshmi
