Subject: SELinux testsuite failure in overlayfs with v4.20-rc kernels
Date: Thu, 13 Dec 2018 09:18:58 +1100 (AEDT) [thread overview]
Message-ID: <alpine.LRH.2.21.1812130915190.5053@namei.org> (raw)
The SELinux testsuite is failing in the overlayfs tests in current -rc
kernels. I bisected the issue to
commit 007ea44892e6fa963a0876a979e34890325c64eb
Author: Miklos Szeredi <mszeredi@redhat.com>

ovl: relax permission checking on underlying layers
Make permission checking more consistent:
- special files don't need any access check on underling fs
- exec permission check doesn't need to be performed on underlying fs

Reverting this commit fixes the testsuite failure.
Is there any more information on the rationale for the change?
