| * NFC: LLCP raw socket supportThierry Escande2012-09-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds support for socket of type SOCK_RAW to LLCP. sk_buff are copied and sent to raw sockets with a 2 bytes extra header: The first byte header contains the nfc adapter index. The second one contains flags: - 0x01 - Direction (0=RX, 1=TX) - 0x02-0x80 - Reserved A raw socket has to be explicitly bound to a nfc adapter. This is achieved by specifying the adapter index to be bound to in the dev_idx field of the sockaddr_nfc_llcp struct passed to bind().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | xmit callback provided by a driver encapsulates upper layers data and sends it to the hardware. So, HCI does not know the exact amount of data being sent and thus can't handle partially sent frames properly. Therefore, the driver must return 0 for completely sent frame or negative for failure.

| * | NFC: Changed HCI and PN544 HCI driver to use the new HCI LLC CoreEric Lapuyade2012-09-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The previous shdlc HCI driver and its header are removed from the tree. PN544 now registers directly with HCI and passes the name of the llc it requires (shdlc). HCI instantiation now allocates the required llc instance.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | NFC is using a number of custom ordered workqueues w/ WQ_MEM_RECLAIM. WQ_MEM_RECLAIM is unnecessary unless NFC is gonna be used as transport for storage device, and all use cases match one work item to one ordered workqueue - IOW, there's no actual ordering going on at all and using system_nrt_wq gives the same behavior.

Section 4.2. Default Tunnel Egress Behaviour. o If the inner ECN field is Not-ECT, the decapsulator MUST NOT propagate any other ECN codepoint onwards. This is because the inner Not-ECT marking is set by transports that rely on dropped packets as an indication of congestion and would not understand or respond to any other ECN codepoint [RFC4774]. Specifically: * If the inner ECN field is Not-ECT and the outer ECN field is CE, the decapsulator MUST drop the packet. * If the inner ECN field is Not-ECT and the outer ECN field is Not-ECT, ECT(0), or ECT(1), the decapsulator MUST forward the outgoing packet with the ECN field cleared to Not-ECT. This patch moves the ECN decap logic out of the individual tunnels into a common place. It also adds logging to allow detecting broken systems that set ECN bits incorrectly when tunneling (or an intermediate router might be changing the header). Overloads rx_frame_error to keep track of ECN related error. Thanks to Chris Wright who caught this while reviewing the new VXLAN tunnel.

This page is used to build fragments for skbs. Its done to increase probability of coalescing small write() into single segments in skbs still in write queue (not yet sent) But it wastes a lot of memory for applications handling many mostly idle sockets, since each socket holds one page in sk->sk_sndmsg_page Its also quite inefficient to build TSO 64KB packets, because we need about 16 pages per skb on arches where PAGE_SIZE = 4096, so we hit page allocator more than wanted. This patch adds a per task frag allocator and uses bigger pages, if available. An automatic fallback is done in case of memory pressure. (up to 32768 bytes per frag, thats order-3 pages on x86) This increases TCP stream performance by 20% on loopback device, but also benefits on other network devices, since 8x less frags are mapped on transmit and unmapped on tx completion. Alexander Duyck mentioned a probable performance win on systems with IOMMU enabled. Its possible some SG enabled hardware cant cope with bigger fragments, but their ndo_start_xmit() should already handle this, splitting a fragment in sub fragments, since some arches have PAGE_SIZE=65536 Successfully tested on various ethernet devices.

The rule: --weekdays Mo --timestart 23:00 --timestop 01:00 looks correct, but it will first match on monday from midnight to 1 a.m. and then again for another hour from 23:00 onwards. This permits userspace to explicitly ignore the day transition and match for a single, continuous time period instead.

* | | | | | | tcp: TCP Fast Open Server - take SYNACK RTT after completing 3WHSNeal Cardwell2012-09-22

Previously we were always taking an RTT sample in tcp_v4_syn_recv_sock(). However, for TCP Fast Open connections tcp_v4_conn_req_fastopen() calls tcp_v4_syn_recv_sock() at the time we receive the SYN. So for TFO we must wait until tcp_rcv_state_process() to take the RTT sample. To fix this, we wait until after TFO calls tcp_v4_syn_recv_sock() before we set the snt_synack timestamp, since tcp_synack_rtt_meas() already ensures that we only take a SYNACK RTT sample if snt_synack is non-zero. To be careful, we only take a snt_synack timestamp when a SYNACK transmit or retransmit succeeds. Signed-off-by: Neal Cardwell <ncardwell@google.com> Signed-off-by: David S.
