Hallyn" <serge@...lyn.com>, selinux@...ho.nsa.gov, linux-security-module@...r.kernel.org Subject: [PATCH] selinux: Fix SBLABEL_MNT for NFS mounts Labelling of files in a NFSv4.2 currently fails with ENOTSUPP because the mount point doesn't have SBLABEL_MNT. Add specific condition for NFS4 filesystems so it gets correctly labeled. Signed-off-by: Tomeu Vizoso <tomeu.vizoso@...labora.com> Cc: J. Bruce Fields <bfields@...hat.com> --- Hi, cannot remotely say that I currently understand how selinux is expected to work within NFS mounts, but this change allowed me to fully boot AOSP with its rootfs and ramdisk on a single NFS share.
