Dag-Erling Smørgrav c4d9a19be3 Fix the length calculation for the final block of a sendfile(2)

transmission which could be tricked into rounding up to the nearest
page size, leaking up to a page of kernel memory.  [13:11]

In IPv6 and NetATM, stop SIOCSIFADDR, SIOCSIFBRDADDR, SIOCSIFDSTADDR
and SIOCSIFNETMASK at the socket layer rather than pass them on to the
link layer without validation or credential checks.  [SA-13:12]

Prevent cross-mount hardlinks between different nullfs mounts of the
same underlying filesystem.  [SA-13:13]
