From 770abc381f374339729c4e4eae18d6e17e6fb314 Mon Sep 17 00:00:00 2001 From: David Howells Date: Thu, 16 Jan 2020 12:23:01 +0800 Subject: [PATCH] afs: Fix SELinux setting security label on /afs [ Upstream commit bcbccaf2edcf1b76f73f890e968babef446151a4 ] Make the AFS dynamic root superblock R/W so that SELinux can set the security label on it. Without this, upgrades to, say, the Fedora filesystem-afs RPM fail if afs is mounted on it because the SELinux label can't be (re-)applied. It might be better to make it possible to bypass the R/O check for LSM label application through setxattr.
