Subject: [PATCH 5/6] ima: verify kernel firmware signatures when using a preallocated buffer
Date: Tue, 1 May 2018 09:48:22 -0400 [thread overview]
Message-ID: <1525182503-13849-6-git-send-email-zohar@linux.vnet.ibm.com> (raw)
In-Reply-To: <1525182503-13849-1-git-send-email-zohar@linux.vnet.ibm.com>
Don't differentiate between kernel_read_file_id READING_FIRMWARE and
READING_FIRMWARE_PREALLOC_BUFFER enumerations.
Fixes: a098ecd firmware: support loading into a pre-allocated buffer (since 4.8)
