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. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
