2017-05-19xfrm: fix state migration copy replay sequence numbersAntony Antony
During xfrm migration copy replay and preplay sequence numbers from the previous state. Here is a tcpdump output showing the problem. 10.0.10.46 is running vanilla kernel, is the IKE/IPsec responder. After the migration it sent wrong sequence number, reset to 1. The migration is from 10.0.0.52 to 10.0.0.53.

2017-05-19batman-adv: fix memory leak when dropping packet from other gatewayAndreas Pape
The skb must be released in the receive handler since b91a2543b4c1 ("batman-adv: Consume skb in receive handlers"). Just returning NET_RX_DROP will no longer automatically free the memory.

2017-05-17tcp: switch TCP TS option (RFC 7323) to 1ms clockEric Dumazet
TCP Timestamps option is defined in RFC 7323 Traditionally on linux, it has been tied to the internal 'jiffies' variable, because it had been a cheap and good enough generator. For TCP flows on the Internet, 1 ms resolution would be much better than 4ms or 10ms (HZ=250 or HZ=100 respectively) For TCP flows in the DC, Google has used usec resolution for more than two years with great success [1] Receive size autotuning (DRS) is indeed more precise and converges faster to optimal window size. This patch converts tp->tcp_mstamp to a plain u64 value storing a 1 usec TCP clock. This choice will allow us to upstream the 1 usec TS option as discussed in IETF 97.

2017-05-17net: sched: introduce tcf block infractructureJiri Pirko
Currently, the filter chains are direcly put into the private structures of qdiscs. In order to be able to have multiple chains per qdisc and to allow filter chains sharing among qdiscs, there is a need for common object that would hold the chains. This introduces such object and calls it "tcf_block". Helpers to get and put the blocks are provided to be called from individual qdisc code. Also, the original filter_list pointers are left in qdisc privs to allow the entry into tcf_block processing without any added overhead of possible multiple pointer dereference on fast path.
