When the kernel calls svc_reserve to downsize the expected size of an RPC

the packet. If a client mounts a NFSv2/3 with sec=krb5i/p, and does I/O then

Add ownership information to mounts.
A new mount flag, MS_SETUSER is used to make a mount owned by a user.
If this flag is specified, then the owner will be set to the current
real user id and the mount will be

In AppArmor, we are interested in pathnames relative to the namespace root.
This is the same as d_path() except for the root where the search ends. Add

The owner doesn't need sysadmin capabilities to call umount().
Similar behavior as umount(8) on mounts having user=UID option in
/etc/mtab. The difference is that umount also checks /etc/fstab,

Add sysctl variables for accounting and limiting the number of user
mounts.
The maximum number of user mounts is set to 1024 by default. This
won't in itself enable user mounts, setting a mount to be owned by

There are numerous problems reported Ubuntu Launchpad, Gentoo Forums
and Sabayon Forums.
