| | | | * | | cfg80211: check wdev->netdev in connection workJohannes Berg2013-05-23

Skip any wdevs that have no netdev to fix this. Cc: stable@vger.kernel.org Reported-by: YanBo <dreamfly281@gmail.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>

This required a new hook for IPv6 functions in the netfilter core to avoid hard dependencies with the ipv6 subsystem when this match is only used for IPv4. * fix connection reuse case in IPVS. Currently, if an reused connection are directed to the same server. If that server is down, those connection would fail. Therefore, clear the connection and choose a new server among the available ones. * fix possible non-nul terminated string sent to user-space if ipt_ULOG is used as the default netfilter logging stub, from Chen Gang. * fix mark logging of IPv6 packets in xt_LOG, from Michal Kubecek. This bug has been there since 2.6.26. * Fix breakage ip_vs_sh due to incorrect structure layout for RCU, from Jan Beulich. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

[..] If I remove the --limit-iface-in from the non-working scenario, so just use the -m addrtype --dst-type LOCAL it works! This happens when LOCAL type matching is requested with --limit-iface-in, and the default ipv6 route is via the interface the packet we test arrived on. Because xt_addrtype uses ip6_route_output, the ipv6 routing implementation creates an unwanted cached entry, and the packet won't make it to the real/expected destination. Silently ignoring --limit-iface-in makes the routing work but it breaks rule matching (--dst-type LOCAL with limit-iface-in is supposed to only match if the dst address is configured on the incoming interface; without --limit-iface-in it will match if the address is reachable via lo). The test should call ipv6_chk_addr() instead. However, this would add a link-time dependency on ipv6. There are two possible solutions: 1) Revert the commit that moved ipt_addrtype to xt_addrtype, and put ipv6 specific code into ip6t_addrtype. 2) add new "nf_ipv6_ops" struct to register pointers to ipv6 functions. While the former might seem preferable, Pablo pointed out that there are more xt modules with link-time dependeny issues regarding ipv6, so lets go for 2).

| * | | | | ipv4: fix redirect handling for TCP packetsMichal Kubecek2013-05-28

This leads to __build_flow_key() getting pointer to IPv4 header of the ICMP redirect packet rather than pointer to the embedded IPv4 header of the packet initiating the redirect. As a result, handling of ICMP redirects initiated by TCP packets is broken. Issue was introduced by 4895c771c ("ipv4: Add FIB nexthop exceptions.")

We must clear IPCB in ip_tunnel_xmit() sooner in case dst_link_failure() is called. Or else skb->cb[] might contain garbage from GSO segmentation layer. A similar fix was tested on linux-3.9, but gre code was refactored in linux-3.10. I'll send patches for stable kernels as well. Many thanks to Daniel for providing reports, patches and testing !

The bug is triggered by sacked_out decreasing relative to prior_sacked, but packets_out remaining the same as pior_packets. This is because the snapshot of prior_packets is taken after tcp_sacktag_write_queue() while prior_sacked is captured before tcp_sacktag_write_queue(). The problem is: tcp_sacktag_write_queue (tcp_match_skb_to_sack() -> tcp_fragment) adjusts the pcount for packets_out and sacked_out (MSS change or other reason). As a result, this delta in pcount is reflected in (prior_sacked - sacked_out) but not in (prior_packets - packets_out). This patch does the following: 1) initializes prior_packets at the start of tcp_ack() so as to capture the delta in packets_out created by tcp_fragment. 2) introduces a new "previous_packets_out" variable that snapshots packets_out right before tcp_clean_rtx_queue, so pkts_acked can be correctly computed as before. 3) Computes pkts_acked using previous_packets_out, and computes newly_acked_sacked using prior_packets.

VHT requires the Wide Bandwidth Channel Switch subelement to be present in the Channel Switch Wrapper element, so the code for that is probably ok (see 802.11ac Draft 4, 8.4.2.165.)

This happens if GSO segmentation is done before stacked device for example. Result is we can send packets from a given TCP flow to different TX queues (if using multiqueue NICS). This generates OOO problems and spurious SACK & retransmits. Fix this by keeping socket pointer set for all segments. This means that every segment must also have a destructor, and the original gso skb truesize must be split on all segments, to keep precise sk->sk_wmem_alloc accounting.

Adding struct net *net in call to nf_logfn() will secure that there always is a vaild net ptr.

| | * | | | | netfilter: nf_{log,queue}: fix compilation without CONFIG_PROC_FSPablo Neira Ayuso2013-05-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes the following compilation error: net/netfilter/nf_log.c:373:38: error: 'struct netns_nf' has no member named 'proc_netfilter' if procfs is not set. The netns support for nf_log, nfnetlink_log and nfnetlink_queue_core requires CONFIG_PROC_FS in the removal path of their respective /proc interface since net->nf.proc_netfilter is undefined in that case.
