Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/klassert/ipsec
Steffen Klassert says:
====================
1) We used the wrong netlink attribute to verify the
lenght of the replay window on async events. Fix this by
using the right netlink attribute.
2) Policy lookups can not match the output interface on forwarding.
Add the needed informations to the flow informations.
3) We update the pmtu when we receive a ICMPV6_DEST_UNREACH message
on IPsec with ipv6. This is wrong and leads to strange fragmented
packets, only ICMPV6_PKT_TOOBIG messages should update the pmtu.
Fix this by removing the ICMPV6_DEST_UNREACH check from the IPsec
protocol error handlers.
4) The legacy IPsec anti replay mechanism supports anti replay
windows up to 32 packets. If a user requests for a bigger
anti replay window, we use 32 packets but pretend that we use
the requested window size. Fix from Fan Du.
5) If asynchronous events are enabled and replay_maxdiff is set to
zero, we generate an async event for every received packet instead
of checking whether a timeout occurred. Fix from Thomas Egerer.
6) Policies need a refcount when the state resolution timer is armed.
Otherwise the timer can fire after the policy is deleted.
7) We might dreference a NULL pointer if the hold_queue is empty,
add a check to avoid this.
