Steffen Klassert says:

====================
1) The transport header did not point to the right place after
   esp/ah processing on tunnel mode in the receive path. As a
   result, the ECN field of the inner header was not set correctly,
   fixes from Li RongQing.

2) We did a null check too late in one of the xfrm_replay advance
   functions. This can lead to a division by zero, fix from
   Nickolai Zeldovich.

3) The size calculation of the hash table missed the muiltplication
   with the actual struct size when the hash table is freed.
   We might call the wrong free function, fix from Michal Kubecek.

4) On IPsec pmtu events we can't access the transport headers of
   the original packet, so force a relookup for all routes
   to notify about the pmtu event.
