After moving the skfp driver, issues with the #include pathing to their locel headers was somehow exposed. Several headers had the incorrect path, so they were not able to be found during compile time. This patch fixes up the path issues to the local headers that need to be included. CC: "Maciej W.

Virtual Machines with emulated e1000 network adapter running on Parallels' server were seeing kernel panics due to the e1000 driver dereferencing an unexpected NULL pointer retrieved from buffer_info->skb. The problem has been addressed for the e1000e driver, but not for the e1000. Since the two drivers share similar code in the affected area, a port of the following e1000e driver commit solves the issue for the e1000 driver: commit 9ed318d5 Author: Tom Herbert <therbert@google.com> Date: Wed May 5 14:02:27 2010 +0000 e1000e: save skb counts in TX to avoid cache misses In e1000_tx_map, precompute number of segements and bytecounts which are derived from fields in skb; these are stored in buffer_info. When cleaning tx in e1000_clean_tx_irq use the values in the associated buffer_info for statistics counting, this eliminates cache misses on skb fields.

Patch series 109f6e39..7361c36c back in 2.6.36 added functionality to allow credentials to work across pid namespaces for packets sent via UNIX sockets. However, the atomic reference counts on pid and credentials caused plenty of cache bouncing when there are numerous threads of the same pid sharing a UNIX socket. This patch mitigates the problem by eliminating extraneous reference counts on pid and credentials on both send and receive path of UNIX sockets. I found a 2x improvement in hackbench's threaded case. On the receive path in unix_dgram_recvmsg, currently there is an increment of reference count on pid and credentials in scm_set_cred. Then there are two decrement of the reference counts. Once in scm_recv and once when skb_free_datagram call skb->destructor function unix_destruct_scm. One pair of increment and decrement of ref count on pid and credentials can be eliminated from the receive path. Until we destroy the skb, we already set a reference when we created the skb on the send side. On the send path, there are two increments of ref count on pid and credentials, once in scm_send and once in unix_scm_to_skb. Then there is a decrement of the reference counts in scm_destroy's call to scm_destroy_cred at the end of unix_dgram_sendmsg functions. One pair of increment and decrement of the reference counts can be removed so we only need to increment the ref counts once. By incorporating these changes, for hackbench running on a 4 socket NHM-EX machine with 40 cores, the execution of hackbench on 50 groups of 20 threads sped up by factor of 2.

This patch implements Proportional Rate Reduction (PRR) for TCP. PRR is an algorithm that determines TCP's sending rate in fast recovery. PRR avoids excessive window reductions and aims for the actual congestion window size at the end of recovery to be as close as possible to the window determined by the congestion control algorithm. PRR also improves accuracy of the amount of data sent during loss recovery. The patch implements the recommended flavor of PRR called PRR-SSRB (Proportional rate reduction with slow start reduction bound) and replaces the existing rate halving algorithm. PRR improves upon the existing Linux fast recovery under a number of conditions including: 1) burst losses where the losses implicitly reduce the amount of outstanding data (pipe) below the ssthresh value selected by the congestion control algorithm and, 2) losses near the end of short flows where application runs out of data to send. As an example, with the existing rate halving implementation a single loss event can cause a connection carrying short Web transactions to go into the slow start mode after the recovery. This is because during recovery Linux pulls the congestion window down to packets_in_flight+1 on every ACK. A short Web response often runs out of new data to send and its pipe reduces to zero by the end of recovery when all its packets are drained from the network. Subsequent HTTP responses using the same connection will have to slow start to raise cwnd to ssthresh. PRR on the other hand aims for the cwnd to be as close as possible to ssthresh by the end of recovery. A description of PRR and a discussion of its performance can be found at the following links: - IETF Draft: http://tools.ietf.org/html/draft-mathis-tcpm-proportional-rate-reduction-01 - IETF Slides: http://www.ietf.org/proceedings/80/slides/tcpm-6.pdf http://tools.ietf.org/agenda/81/slides/tcpm-2.pdf - Paper to appear in Internet Measurements Conference (IMC) 2011: Improving TCP Loss Recovery Nandita Dukkipati, Matt Mathis, Yuchung Cheng Signed-off-by: NNandita Dukkipati <nanditad@google.com> Signed-off-by: NDavid S.

1) Blocks can be configured with non-static frame-size. 2) Read/poll is at a block-level(as opposed to packet-level). 3) Added poll timeout to avoid indefinite user-space wait on idle links. 4) Added user-configurable knobs: 4.1) block::timeout. 4.2) tpkt_hdr::sk_rxhash. Changes: C1) tpacket_rcv() C1.1) packet_current_frame() is replaced by packet_current_rx_frame() The bulk of the processing is then moved in the following chain: packet_current_rx_frame() __packet_lookup_frame_in_block fill_curr_block() or retire_current_block dispatch_next_block or return NULL(queue is plugged/paused) Signed-off-by: NChetan Loke <loke.chetan@gmail.com> Signed-off-by: NDavid S.
