2012-07-19net-tcp: Fast Open client - cookie-less modeYuchung Cheng
In trusted networks, e.g., intranet, data-center, the client does not need to use Fast Open cookie to mitigate DoS attacks. In cookie-less mode, sendmsg() with MSG_FASTOPEN flag will send SYN-data regardless of cookie availability.

2012-07-19net-tcp: Fast Open client - sendmsg(MSG_FASTOPEN)Yuchung Cheng
sendmsg() (or sendto()) with MSG_FASTOPEN is a combo of connect(2) and write(2). The application should replace connect() with it to send data in the opening SYN packet. For blocking socket, sendmsg() blocks until all the data are buffered locally and the handshake is completed like connect() call. It returns similar errno like connect() if the TCP handshake fails. For non-blocking socket, it returns the number of bytes queued (and transmitted in the SYN-data packet) if cookie is available. If cookie is not available, it transmits a data-less SYN packet with Fast Open cookie request option and returns -EINPROGRESS like connect(). Using MSG_FASTOPEN on connecting or connected socket will result in simlar errno like repeating connect() calls. Therefore the application should only use this flag on new sockets. The buffer size of sendmsg() is independent of the MSS of the connection. Signed-off-by: Yuchung Cheng <ycheng@google.com> Acked-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.

2012-07-17tcp: implement RFC 5961 3.2Eric Dumazet
Implement the RFC 5691 mitigation against Blind Reset attack using RST bit. Idea is to validate incoming RST sequence, to match RCV.NXT value, instead of previouly accepted window : (RCV.NXT <= SEG.SEQ < RCV.NXT+RCV.WND) If sequence is in window but not an exact match, send a "challenge ACK", so that the other part can resend an RST with the appropriate sequence. Add a new sysctl, tcp_challenge_ack_limit, to limit number of challenge ACK sent per second. Add a new SNMP counter to count number of challenge acks sent.

2012-07-11tcp: TCP Small QueuesEric Dumazet
This introduce TSQ (TCP Small Queues) TSQ goal is to reduce number of TCP packets in xmit queues (qdisc & device queues), to reduce RTT and cwnd bias, part of the bufferbloat problem. sk->sk_wmem_alloc not allowed to grow above a given limit, allowing no more than ~128KB [1] per tcp socket in qdisc/dev layers at a given time. TSO packets are sized/capped to half the limit, so that we have two TSO packets in flight, allowing better bandwidth use. As a side effect, setting the limit to 40000 automatically reduces the standard gso max limit (65536) to 40000/2 : It can help to reduce latencies of high prio packets, having smaller TSO packets. This means we divert sock_wfree() to a tcp_wfree() handler, to queue/send following frames when skb_orphan() [2] is called for the already queued skbs. Results on my dev machines (tg3/ixgbe nics) are really impressive, using standard pfifo_fast, and with or without TSO/GSO. Without reduction of nominal bandwidth, we have reduction of buffering per bulk sender : < 1ms on Gbit (instead of 50ms with TSO) < 8ms on 100Mbit (instead of 132 ms) I no longer have 4 MBytes backlogged in qdisc by a single netperf session, and both side socket autotuning no longer use 4 Mbytes. As skb destructor cannot restart xmit itself ( as qdisc lock might be taken at this point ), we delegate the work to a tasklet. We use one tasklest per cpu for performance reasons. If tasklet finds a socket owned by the user, it sets TSQ_OWNED flag. This flag is tested in a new protocol method called from release_sock(), to eventually send new segments. [1] New /proc/sys/net/ipv4/tcp_limit_output_bytes tunable [2] skb_orphan() is usually called at TX completion time, but some drivers call it in their start_xmit() handler. These drivers should at least use BQL, or else a single TCP session can still fill the whole NIC TX ring, since TSQ will have no effect.

Define two new "compatible" values for Ethernet PHYs. "ethernet-phy-ieee802.3-c22" and "ethernet-phy-ieee802.3-c45" are used to indicate a PHY uses the corresponding protocol. If a PHY is "compatible" with "ethernet-phy-ieee802.3-c45", we indicate this so that get_phy_device() can properly probe the device. If get_phy_device() fails, it was probably due to failing the probe of the PHY identifier registers. Since we have the device tree telling us the PHY exists, go ahead and add it anyhow with a phy_id of zero. There may be a driver match based on the "compatible" property.

2012-06-25stable: Allow merging of backports for serious user-visible performance issuesMel Gorman
Distribution kernel maintainers routinely backport fixes for users that were deemed important but not "something critical" as defined by the rules. To users of these kernels they are very serious and failing to fix them reduces the value of -stable. The problem is that the patches fixing these issues are often subtle and prone to regressions in other ways and need greater care and attention. To combat this, these "serious" backports should have a higher barrier to entry. This patch relaxes the rules to allow a distribution maintainer to merge to -stable a backported patch or small series that fixes a "serious" user-visible performance issue. They should include additional information on the user-visible bug affected and a link to the bugzilla entry if available. The same rules about the patch being already in mainline still apply.

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging Pull staging tree fixes from Greg Kroah-Hartman: "Here are a number of small fixes for the drivers/staging tree, as well as iio and pstore drivers (which came from the staging tree in the 3.5-rc1 merge). All of these are tiny, but resolve issues that people have been reporting. There's also a documentation update to reflect what the iio drivers really are doing, which is good to get straightened out.

2012-06-18batman-adv: Add get_ethtool_stats() supportMartin Hundebøll
Added additional counters in a bat_stats structure, which are exported through the ethtool api. The counters are specific to batman-adv and includes: forwarded packets and bytes management packets and bytes (aggregated OGMs at this point) translation table packets New counters are added by extending "enum bat_counters" in types.h and adding corresponding descriptive string(s) to bat_counters_strings in soft-iface.c. Counters are increased by calling batadv_add_counter() and incremented by one by calling batadv_inc_counter().
