-Subject: net: Use ns_capable_noaudit() when determining net sysctl permissions
-
-From: Tyler Hicks <tyhicks@canonical.com>
-
-commit d6e0d306449bcb5fa3c80e7a3edf11d45abf9ae9 upstream.
-
-The capability check should not be audited since it is only being used
-to determine the inode permissions. A failed check does not indicate a
-violation of security policy but, when an LSM is enabled, a denial audit
-message was being generated.
-
-The denial audit message caused confusion for some application authors
-because root-running Go applications always triggered the denial. To
-prevent this confusion, the capability check in net_ctl_permissions() is
-switched to the noaudit variant.
