Merge branch 'ip-Use-rb-trees-for-IP-frag-queue'
Peter Oskolkov says:
====================
ip: Use rb trees for IP frag queue.
This patchset
* changes IPv4 defrag behavior to match that of IPv6: overlapping
fragments now cause the whole IP datagram to be discarded (suggested
by David Miller): there are no legitimate use cases for overlapping
fragments;
* changes IPv4 defrag queue from a list to a rb tree (suggested
by Eric Dumazet): this change removes a potential attach vector.
Upcoming patches will contain similar changes for IPv6 frag queue,
as well as a comprehensive IP defrag self-test (temporarily delayed).
