Subject: [PATCH ghak138 v2 4/4] audit: move audit_return_fixup before the filters
Date: Thu, 25 Aug 2022 15:32:40 -0400 [thread overview]
Message-ID: <0129ccc2378a772a7c38090ce2cea0fda44c8479.1661449312.git.rgb@redhat.com> (raw)
In-Reply-To: <cover.1661449312.git.rgb@redhat.com>
The success and return_code are needed by the filters. Move
audit_return_fixup() before the filters. This was causing syscall
auditing events to be missed.
Link: https://github.com/linux-audit/audit-kernel/issues/138
Fixes: 12c5e81d3fd0 ("audit: prepare audit_context for use in calling contexts beyond syscalls")
