2017-02-07	tcp: replace dst_confirm with sk_dst_confirm	Julian Anastasov	1	-0/+2
	When same struct dst_entry can be used for many different neighbours we can not use it for pending confirmations. Use the new sk_dst_confirm() helper to propagate the indication from received packets to sock_confirm_neigh(). Reported-by: YueHaibing <yuehaibing@huawei.com> Fixes: 5110effee8fd ("net: Do delayed neigh confirmation.") Fixes: f2bb4bedf35d ("ipv4: Cache output routes in fib_info nexthops.")

2017-02-03	tcp: clear pfmemalloc on outgoing skb	Eric Dumazet	1	-0/+7
	Josef Bacik diagnosed following problem : I was seeing random disconnects while testing NBD over loopback. This turned out to be because NBD sets pfmemalloc on it's socket, however the receiving side is a user space application so does not have pfmemalloc set on its socket. This means that sk_filter_trim_cap will simply drop this packet, under the assumption that the other side will simply retransmit. Well we do retransmit, and then the packet is just dropped again for the same reason. It seems the better way to address this problem is to clear pfmemalloc in the TCP transmit path. pfmemalloc strict control really makes sense on the receive path.

2017-02-01	tcp: fix 0 divide in __tcp_select_window()	Eric Dumazet	1	-2/+4
	syszkaller fuzzer was able to trigger a divide by zero, when TCP window scaling is not enabled. SO_RCVBUF can be used not only to increase sk_rcvbuf, also to decrease it below current receive buffers utilization. If mss is negative or 0, just return a zero TCP window.
