apparmor: add mount mediation
Add basic mount mediation. That allows controlling based on basic
mount parameters. It does not include special mount parameters for
apparmor, super block labeling, or any triggers for apparmor namespace
parameter modifications on pivot root.
default userspace policy rules have the form of
MOUNT RULE = ( MOUNT | REMOUNT | UMOUNT )
MOUNT = [ QUALIFIERS ] 'mount' [ MOUNT CONDITIONS ] [ SOURCE FILEGLOB ]
[ '->' MOUNTPOINT FILEGLOB ]
REMOUNT = [ QUALIFIERS ] 'remount' [ MOUNT CONDITIONS ]
MOUNTPOINT FILEGLOB
UMOUNT = [ QUALIFIERS ] 'umount' [ MOUNT CONDITIONS ] MOUNTPOINT FILEGLOB
MOUNT CONDITIONS = [ ( 'fstype' | 'vfstype' ) ( '=' | 'in' )
MOUNT FSTYPE EXPRESSION ]
[ 'options' ( '=' | 'in' ) MOUNT FLAGS EXPRESSION ]
MOUNT FSTYPE EXPRESSION = ( MOUNT FSTYPE LIST | MOUNT EXPRESSION )
MOUNT FSTYPE LIST = Comma separated list of valid filesystem and
virtual filesystem types (eg ext4, debugfs, etc)
MOUNT FLAGS EXPRESSION = ( MOUNT FLAGS LIST | MOUNT EXPRESSION )
MOUNT FLAGS LIST = Comma separated list of MOUNT FLAGS.
MOUNT FLAGS = ( 'ro' | 'rw' | 'nosuid' | 'suid' | 'nodev' | 'dev' |
'noexec' | 'exec' | 'sync' | 'async' | 'remount' |
'mand' | 'nomand' | 'dirsync' | 'noatime' | 'atime' |
'nodiratime' | 'diratime' | 'bind' | 'rbind' | 'move' |
'verbose' | 'silent' | 'loud' | 'acl' | 'noacl' |
'unbindable' | 'runbindable' | 'private' | 'rprivate' |
'slave' | 'rslave' | 'shared' | 'rshared' |
'relatime' | 'norelatime' | 'iversion' | 'noiversion' |
'strictatime' | 'nouser' | 'user' )
MOUNT EXPRESSION = ( ALPHANUMERIC | AARE ) ...
PIVOT ROOT RULE = [ QUALIFIERS ] pivot_root [ oldroot=OLD PUT FILEGLOB ]
[ NEW ROOT FILEGLOB ]
SOURCE FILEGLOB = FILEGLOB
MOUNTPOINT FILEGLOB = FILEGLOB
eg.
mount,
mount /dev/foo,
mount options=ro /dev/foo -> /mnt/,
mount options in (ro,atime) /dev/foo -> /mnt/,
mount options=ro options=atime,
