* net_sched: better precise estimation on packet length for untrusted packetsJason Wang2013-03-261-1/+7
| | | | | | | | | | | gso_segs were reset to zero when kernel receive packets from untrusted source. But we use this zero value to estimate precise packet len which is wrong. So this patch tries to estimate the correct gso_segs value before using it in qdisc_pkt_len_init().

* netback: set transport header before passing it to kernelJason Wang2013-03-261-0/+12
| | | | | | | | | | | | | | | | | Currently, for the packets receives from netback, before doing header check, kernel just reset the transport header in netif_receive_skb() which pretends non l4 header. This is suboptimal for precise packet length estimation (introduced in 1def9238: net_sched: more precise pkt_len computation) which needs correct l4 header for gso packets. The patch just reuse the header probed by netback for partial checksum packets and tries to use skb_flow_dissect() for other cases, if both fail, just pretend no l4 header.

* packet: set transport header before doing xmitJason Wang2013-03-261-0/+21
| | | | | | | | | | | | | Set the transport header for 1) some drivers (e.g ixgbe needs l4 header to do atr) 2) precise packet length estimation (introduced in 1def9238) needs l4 header to compute header length. So this patch first tries to get l4 header for packet socket through skb_flow_dissect(), and pretend no l4 header if skb_flow_dissect() fails.

* Merge branch '6lowpan'David S. Miller2013-03-266-30/+128
|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Tony Cheneau says: ==================== This patchset fixes serious bugs within the 6LoWPAN modules. I wrote a script (available at [1]) to prove the issues are real. One can try and see that without these patches, most of the test fail (e.g. packet dropped by the receiver or node crashing). With all patches applied, all tests succeed. The tests themselves are very basic: sending ICMP packets, sending UDP packets, sending TCP packets, varying size of the packets. This actually triggers some 6LoWPAN specific code, namely fragmentation, packet reassembly and header compression. This code passed the checkpatch.pl tool with a few warnings, that I believe are OK. It should apply cleanly on the latest net-next. [1]: https://github.com/tcheneau/linux802154-regression-tests ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

| * firewire net, ipv4 arp: Extend hardware address and remove driver-level ↵YOSHIFUJI Hideaki / 吉藤英明2013-03-264-135/+82
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | packet inspection. Inspection of upper layer protocol is considered harmful, especially if it is about ARP or other stateful upper layer protocol; driver cannot (and should not) have full state of them. IPv4 over Firewire module used to inspect ARP (both in sending path and in receiving path), and record peer's GUID, max packet size, max speed and fifo address. This patch removes such inspection by extending our "hardware address" definition to include other information as well: max packet size, max speed and fifo. By doing this, The neighbour module in networking subsystem can cache them. Note: As we have started ignoring sspd and max_rec in ARP/NDP, those information will not be used in the driver when sending. When a packet is being sent, the IP layer fills our pseudo header with the extended "hardware address", including GUID and fifo. The driver can look-up node-id (the real but rather volatile low-level address) by GUID, and then the module can send the packet to the wire using parameters provided in the extendedn hardware address. This approach is realistic because IP over IEEE1394 (RFC2734) and IPv6 over IEEE1394 (RFC3146) share same "hardware address" format in their address resolution protocols. Here, extended "hardware address" is defined as follows: union fwnet_hwaddr { u8 u[16]; struct { __be64 uniq_id; /* EUI-64 */ u8 max_rec; /* max packet size */ u8 sspd; /* max speed */ __be16 fifo_hi; /* hi 16bits of FIFO addr */ __be32 fifo_lo; /* lo 32bits of FIFO addr */ } __packed uc; }; Note that Hardware address is declared as union, so that we can map full IP address into this, when implementing MCAP (Multicast Cannel Allocation Protocol) for IPv6, but IP and ARP subsystem do not need to know this format in detail. One difference between original ARP (RFC826) and 1394 ARP (RFC2734) is that 1394 ARP Request/Reply do not contain the target hardware address field (aka ar$tha). This difference is handled in the ARP subsystem. CC: Stephan Gatzka <stephan.gatzka@gmail.com> Signed-off-by: YOSHIFUJI Hideaki <yoshfuji@linux-ipv6.org> Signed-off-by: David S.

As I noted earlier, RFC 2734:1999 and RFC 3146:2001 were apparently | written with a too simplistic notion of IEEE 1394 bus topology, resulting | in max_rec and sspd in ARP-1394 and NDP-1394 to be useless, IMO. | | Consider a bus like this: | | A ---- B ==== C | | A, B, C are all IP-over-1394 capable nodes. ---- is an S400 cable hop, | and ==== is an S800 cable hop. | | In case of unicasts or multicasts in which node A is involved as | transmitter or receiver, as well as in case of broadcasts, the speeds | S100, S200, S400 work and speed S400 is optimal. | | In case of anything else, IOW in case of unicasts or multicasts in which | only nodes B and C are involved, the speeds S100, S200, S400, S800 work | and speed S800 is optimal. | | Clearly, node A should indicate sspd = S400 in its ARP or NDP packets. | But which sspd should nodes B and C set there? Maybe they set S400, which | would work but would waste half of the available bandwidth in the second | case. Or maybe they set S800, which is OK in the second case but would | prohibit any communication with node A if blindly taken for correct. | | On the other hand, firewire-core *always* gives us the correct and optimum | peer-to-peer speed and asynchronous packet payload, no matter how simple | or complex the bus topology is and no matter in which temporal order nodes | join the bus and are discovered.

| * netfilter: nf_conntrack: speed up module removal path if netns in useVladimir Davydov2013-03-193-20/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The patch introduces nf_conntrack_cleanup_net_list(), which cleanups nf_conntrack for a list of netns and calls synchronize_net() only once for them all. This should reduce netns destruction time. I've measured cleanup time for 1k dummy net ns.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | nfqnl_build_packet_message() actually copy the packet inside the netlink message, while it can instead use zero copy. Make sure the skb 'copy' is the last component of the cooked netlink message, as we cant add anything after it. Patch cooked in Copenhagen at Netfilter Workshop ;) Still to be addressed in separate patches : -GRO/GSO packets are segmented in nf_queue() and checksummed in nfqnl_build_packet_message(). Proper support for GSO/GRO packets (no segmentation, and no checksumming) needs application cooperation, if we want no regressions.
