2014-01-15net: Add trace events for all receive entry points, exposing more skb fieldsBen Hutchings1-39/+61
The existing net/netif_rx and net/netif_receive_skb trace events provide little information about the skb, nor do they indicate how it entered the stack. Add trace events at entry of each of the exported functions, including most fields that are likely to be interesting for debugging driver datapath behaviour. Split netif_rx() and netif_receive_skb() so that internal calls are not traced. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>

The existing net/net_dev_xmit trace event provides little information about the skb that has been passed to the driver, and it is not simple to add more since the skb may already have been freed at the point the event is emitted. Add a separate trace event before the skb is passed to the driver, including most fields that are likely to be interesting for debugging driver datapath behaviour.

This patch adds a function to set up the partial checksum offset for IP packets (and optionally re-calculate the pseudo-header checksum) into the core network code. The implementation was previously private and duplicated between xen-netback and xen-netfront, however it is not xen-specific and is potentially useful to any network driver.

2014-01-14inet_diag: fix inet_diag_dump_icsk() to use correct state for timewait socketsNeal Cardwell1-1/+4
Fix inet_diag_dump_icsk() to reflect the fact that both TCP_TIME_WAIT and TCP_FIN_WAIT2 connections are represented by inet_timewait_sock (not just TIME_WAIT), and for such sockets the tw_substate field holds the real state, which can be either TCP_TIME_WAIT or TCP_FIN_WAIT2. This brings the inet_diag state-matching code in line with the field it uses to populate idiag_state. This is also analogous to the info exported in /proc/net/tcp, where get_tcp4_sock() exports sk->sk_state and get_timewait4_sock() exports tw->tw_substate. Before fixing this, (a) neither "ss -nemoi" nor "ss -nemoi state fin-wait-2" would return a socket in TCP_FIN_WAIT2; and (b) "ss -nemoi state time-wait" would also return sockets in state TCP_FIN_WAIT2. This is an old bug that predates 05dbc7b ("tcp/dccp: remove twchain").

2014-01-13net: gro: change GRO overflow strategyEric Dumazet1-2/+15
GRO layer has a limit of 8 flows being held in GRO list, for performance reason. When a packet comes for a flow not yet in the list, and list is full, we immediately give it to upper stacks, lowering aggregation performance. With TSO auto sizing and FQ packet scheduler, this situation happens more often. This patch changes strategy to simply evict the oldest flow of the list. This works better because of the nature of packet trains for which GRO is efficient. This also has the effect of lowering the GRO latency if many flows are competing. Tested : Used a 40Gbps NIC, with 4 RX queues, and 200 concurrent TCP_STREAM netperf. Before patch, aggregate rate is 11Gbps (while a single flow can reach 30Gbps) After patch, line rate is reached.

This new ip_no_pmtu_disc mode only allowes fragmentation-needed errors to be honored by protocols which do more stringent validation on the ICMP's packet payload. This knob is useful for people who e.g. want to run an unmodified DNS server in a namespace where they need to use pmtu for TCP connections (as they are used for zone transfers or fallback for requests) but don't want to use possibly spoofed UDP pmtu information. Currently the whitelisted protocols are TCP, SCTP and DCCP as they check if the returned packet is in the window or if the association is valid.

2014-01-13ipv6: introduce ip6_dst_mtu_forward and protect forwarding path with itHannes Frederic Sowa1-1/+22
In the IPv6 forwarding path we are only concerend about the outgoing interface MTU, but also respect locked MTUs on routes. Tunnel provider or IPSEC already have to recheck and if needed send PtB notifications to the sending host in case the data does not fit into the packet with added headers (we only know the final header sizes there, while also using path MTU information). The reason for this change is, that path MTU information can be injected into the kernel via e.g. icmp_err protocol handler without verification of local sockets. As such, this could cause the IPv6 forwarding path to wrongfully emit Packet-too-Big errors and drop IPv6 packets.

2014-01-13ipv4: introduce ip_dst_mtu_maybe_forward and protect forwarding path against ↵Hannes Frederic Sowa4-8/+17
pmtu spoofing While forwarding we should not use the protocol path mtu to calculate the mtu for a forwarded packet but instead use the interface mtu. We mark forwarded skbs in ip_forward with IPSKB_FORWARDED, which was introduced for multicast forwarding. But as it does not conflict with our usage in unicast code path it is perfect for reuse. I moved the functions ip_sk_accept_pmtu, ip_sk_use_pmtu and ip_skb_dst_mtu along with the new ip_dst_mtu_maybe_forward to net/ip.h to fix circular dependencies because of IPSKB_FORWARDED. Because someone might have written a software which does probe destinations manually and expects the kernel to honour those path mtus I introduced a new per-namespace "ip_forward_use_pmtu" knob so someone can disable this new behaviour. We also still use mtus which are locked on a route for forwarding. The reason for this change is, that path mtus information can be injected into the kernel via e.g. icmp_err protocol handler without verification of local sockets. As such, this could cause the IPv4 forwarding path to wrongfully emit fragmentation needed notifications or start to fragment packets along a path. Tunnel and ipsec output paths clear IPCB again, thus IPSKB_FORWARDED won't be set and further fragmentation logic will use the path mtu to determine the fragmentation size. They also recheck packet size with help of path mtu discovery and report appropriate errors.

2014-01-12batman-adv: consider outgoing interface in OGM sendingSimon Wunderlich3-64/+115
The current OGM sending an aggregation functionality decides on which interfaces a packet should be sent when it parses the forward packet struct. However, with the network wide multi interface optimization the outgoing interface is decided by the OGM processing function. This is reflected by moving the decision in the OGM processing function and add the outgoing interface in the forwarding packet struct. This practically implies that an OGM may be added multiple times (once per outgoing interface), and this also affects aggregation which needs to consider the outgoing interface as well.

Beyond that, ath9k, brcmfmac, mwifiex, and wil6210 get their usual level of attention. The wl1251 driver gets a number of updates, and there are a handful of other bits here and there. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2014-01-10net: core: explicitly select a txq before doing l2 forwardingJason Wang5-19/+30
Currently, the tx queue were selected implicitly in ndo_dfwd_start_xmit(). The will cause several issues: - NETIF_F_LLTX were removed for macvlan, so txq lock were done for macvlan instead of lower device which misses the necessary txq synchronization for lower device such as txq stopping or frozen required by dev watchdog or control path. - dev_hard_start_xmit() was called with NULL txq which bypasses the net device watchdog. - dev_hard_start_xmit() does not check txq everywhere which will lead a crash when tso is disabled for lower device. Fix this by explicitly introducing a new param for .ndo_select_queue() for just selecting queues in the case of l2 forwarding offload. netdev_pick_tx() was also extended to accept this parameter and dev_queue_xmit_accel() was used to do l2 forwarding transmission. With this fixes, NETIF_F_LLTX could be preserved for macvlan and there's no need to check txq against NULL in dev_hard_start_xmit(). Also there's no need to keep a dedicated ndo_dfwd_start_xmit() and we can just reuse the code of dev_queue_xmit() to do the transmission. In the future, it was also required for macvtap l2 forwarding support since it provides a necessary synchronization method.

For the NFC bits, Samuel says: "This pull request only contains one fix for a regression introduced with commit e29a9e2ae165620d. Without this fix, we can not establish a p2p link in target mode. Only initiator mode works." For the iwlwifi bits, Emmanuel says: "It only includes new device IDs so it's not vital. If you have a pull request to net.git anyway, I'd happy to have this in." ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
