Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/klassert/ipsec
Steffen Klassert says:
====================
pull request (net): ipsec 2016-05-04
1) The flowcache can hit an OOM condition if too
many entries are in the gc_list. Fix this by
counting the entries in the gc_list and refuse
new allocations if the value is too high.
2) The inner headers are invalid after a xfrm transformation,
so reset the skb encapsulation field to ensure nobody tries
access the inner headers. Otherwise tunnel devices stacked
on top of xfrm may build the outer headers based on wrong
informations.
3) Add pmtu handling to vti, we need it to report
pmtu informations for local generated packets.
Please pull or let me know if there are problems.
