From 06b53b02945e3021addc6af2da3ac999d2221d23 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Thomas=20Wei=C3=9Fschuh?= Date: Mon, 9 Jan 2023 23:59:41 +0000 Subject: [PATCH] certs: make blacklisted hash available in klog MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit One common situation triggering this log statement are duplicate hashes reported by the system firmware. These duplicates should be removed from the firmware. Without logging the blacklisted hash triggering the issue however the users can not report it properly to the firmware vendors and the firmware vendors can not easily see which specific hash is duplicated. While changing the log message also use the dedicated ERR_PTR format placeholder for the returned error value.
