when selinux is on it can change quota usage due to extra xattr blocks. Mounting with a context prevents this. We already do so for xfs in general because so many things look at detailed on-disk format, and extra xattrs confuses those tests. For other filesystems, we've left selinux alone so far, as that seemed the best way to test. However, it throws quota accounting off, so add a fixup in _qmount() Signed-off-by: Eric Sandeen <sandeen@xxxxxxxxxx> --- diff --git a/common.quota b/common.quota index d32e285..87a766c 100644 --- a/common.quota +++ b/common.quota @@ -131,8 +131,17 @@ _choose_prid() _qmount() { + # SELinux adds extra xattrs which can mess up our expected usage. + # So, mount with a context, and they won't be created + # nfs_t is a "liberal" context so we can use it. + # Only set it if we didn't inherit SELINUX_MOUNT_OPTIONS for + # all mounts anyway. + if [ -z "$SELINUX_MOUNT_OPTIONS" -a -x /usr/sbin/selinuxenabled ] && /usr/sbin/selinuxenabled; then + QUOTA_SELINUX_MOUNT_OPTIONS="-o context=system_u:object_r:nfs_t:s0" + fi + umount $SCRATCH_DEV >/dev/null 2>&1 - _scratch_mount || _fail "qmount failed" + _scratch_mount $QUOTA_SELINUX_MOUNT_OPTIONS || _fail "qmount failed" chmod ugo+rwx $SCRATCH_MNT } _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
