UBUNTU: SAUCE: apparmor: Add the ability to mediate mount
Add the ability for apparmor to do mediation of mount operations. Mount
rules require an updated apparmor_parser (2.8 series) for policy compilation.
The basic form of the rules are.
[audit] [deny] mount [conds]* [device] [ -> [conds] path],
[audit] [deny] remount [conds]* [path],
[audit] [deny] umount [conds]* [path],
[audit] [deny] pivotroot [oldroot=<value>] <path>
remount is just a short cut for mount options=remount
where [conds] can be
fstype=<expr>
options=<expr>
Example mount commands
mount, # allow all mounts, but not umount or pivotroot
mount fstype=procfs, # allow mounting procfs anywhere
mount options=(bind, ro) /foo -> /bar, # readonly bind mount
mount /dev/sda -> /mnt,
mount /dev/sd** -> /mnt/**,
mount fstype=overlayfs options=(rw,upperdir=/tmp/upper/,lowerdir=/) -> /mnt/
umount,
umount /m*,
