From 8c2f516c99f0b7e59c53158f4d7a7fe229c5aea8 Mon Sep 17 00:00:00 2001 From: Bruno Meneguele Date: Fri, 4 Sep 2020 16:41:00 -0300 Subject: integrity: include keyring name for unknown key request Depending on the IMA policy rule a key may be searched for in multiple keyrings (e.g. .ima and .platform) and possibly not found. This patch improves feedback by including the keyring "description" (name) in the error message.
