2013-12-22ipv4: consistent reporting of pmtu data in case of corkingHannes Frederic Sowa
We report different pmtu values back on the first write and on further writes on an corked socket. Also don't include the dst.header_len (respectively exthdrlen) as this should already be dealt with by the interface mtu of the outgoing (virtual) interface and policy of that interface should dictate if fragmentation should happen. Instead reduce the pmtu data by IP options as we do for IPv6. Make the same changes for ip_append_data, where we did not care about options or dst.header_len at all.

2013-12-21ipv6: move ip6_sk_accept_pmtu from generic pmtu update path to ipv6 oneHannes Frederic Sowa
In commit 93b36cf3425b9b ("ipv6: support IPV6_PMTU_INTERFACE on sockets") I made a horrible mistake to add ip6_sk_accept_pmtu to the generic sctp_icmp_frag_needed path. This results in build warnings if IPv6 is disabled which were luckily caught by Fengguang's kbuild bot. But it also leads to a kernel panic IPv4 frag-needed packet is received.

Thanks to commits 41063e9 (ipv4: Early TCP socket demux) and 421b388 (udp: ipv4: Add udp early demux) it is now possible to parse UID and GID socket info also for incoming TCP and UDP connections. Having this info available, it is convenient to let NFQUEUE parse it in order to improve and refine the traffic analysis in userspace.

2013-12-20tcp: autocork should not hold first packet in write queueEric Dumazet
Willem noticed a TCP_RR regression caused by TCP autocorking on a Mellanox test bed. MLX4_EN_TX_COAL_TIME is 16 us, which can be right above RTT between hosts. We can receive a ACK for a packet still in NIC TX ring buffer or in a softnet completion queue. Fix this by always pushing the skb if it is at the head of write queue. Also, as TX completion is lockless, it's safer to perform sk_wmem_alloc test after setting TSQ_THROTTLED. erd:~# MIB="MIN_LATENCY,MEAN_LATENCY,MAX_LATENCY,P99_LATENCY,STDDEV_LATENCY" erd:~# ./netperf -H remote -t TCP_RR -- -o $MIB | tail -n 1 (repeat 3 times) Before patch : 18,1049.87,41004,39631,6295.47 17,239.52,40804,48,2912.79 18,348.40,40877,54,3573.39 After patch : 18,22.84,4606,38,16.39 17,21.56,2871,36,13.51 17,22.46,2705,37,11.83 Reported-by: Willem de Bruijn <willemb@google.com> Signed-off-by: Eric Dumazet <edumazet@google.com> Fixes: f54b311142a9 ("tcp: auto corking") Signed-off-by: David S.

In nft's nft_exthdr_eval() routine we process IPv6 extension header through invoking ipv6_find_hdr(), but we call it with an uninitialized offset variable that contains some stack value. In ipv6_find_hdr() we then test if the value of offset != 0 and call skb_header_pointer() on that offset in order to map struct ipv6hdr into it. Fix it up by initializing offset to 0 as it was probably intended to be.

git://git.kernel.org/pub/scm/linux/kernel/git/klassert/ipsec-next Steffen Klassert says: ==================== pull request (net-next): ipsec-next 2013-12-19 1) Use the user supplied policy index instead of a generated one if present. From Fan Du. 2) Make xfrm migration namespace aware. From Fan Du. 3) Make the xfrm state and policy locks namespace aware. From Fan Du. 4) Remove ancient sleeping when the SA is in acquire state, we now queue packets to the policy instead. This replaces the sleeping code. 5) Remove FLOWI_FLAG_CAN_SLEEP. This was used to notify xfrm about the posibility to sleep. The sleeping code is gone, so remove it. 6) Check user specified spi for IPComp. Thr spi for IPcomp is only 16 bit wide, so check for a valid value. From Fan Du. 7) Export verify_userspi_info to check for valid user supplied spi ranges with pfkey and netlink. From Fan Du. 8) RFC3173 states that if the total size of a compressed payload and the IPComp header is not smaller than the size of the original payload, the IP datagram must be sent in the original non-compressed form. These packets are dropped by the inbound policy check because they are not transformed. Document the need to set 'level use' for IPcomp to receive such packets anyway. From Fan Du. Please pull or let me know if there are problems. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2013-12-19ipv6: always set the new created dst's from in ip6_rt_copyLi RongQing
ip6_rt_copy only sets dst.from if ort has flag RTF_ADDRCONF and RTF_DEFAULT. but the prefix routes which did get installed by hand locally can have an expiration, and no any flag combination which can ensure a potential from does never expire, so we should always set the new created dst's from. This also fixes the new created dst is always expired since the ort, which is created by RA, maybe has RTF_EXPIRES and RTF_ADDRCONF, but no RTF_DEFAULT.
