Enable the tx/rx aggregation which could contain one or more packets for each bulk in/out. This could reduce the loading of the host controller by sending less bulk transfer.

2013-08-15Merge branch 'x-netns'David S. Miller
Nicolas Dichtel says: ==================== This series is a follow up of the previous series whcih adds this functionality for sit tunnels. The goal is to add x-netns support for the module ipip and ip6_tunnel, ie. the encapsulation addresses and the network device are not owned by the same namespace. Note that the two first patches are cleanups. Example to configure an ipip tunnel: modprobe ipip ip netns add netns1 ip link add ipip1 type ipip remote 10.16.0.121 local 10.16.0.249 ip l s ipip1 netns netns1 ip netns exec netns1 ip l s lo up ip netns exec netns1 ip l s ipip1 up ip netns exec netns1 ip a a dev ipip1 192.168.2.123 remote 192.168.2.121 or an ip6_tunnel: modprobe ip6_tunnel ip netns add netns1 ip link add ip6tnl1 type ip6tnl remote 2001:660:3008:c1c3::121 local 2001:660:3008:c1c3::123 ip l s ip6tnl1 netns netns1 ip netns exec netns1 ip l s lo up ip netns exec netns1 ip l s ip6tnl1 up ip netns exec netns1 ip a a dev ip6tnl1 192.168.1.123 remote 192.168.1.121 ip netns exec netns1 ip -6 a a dev ip6tnl1 2001:1235::123 remote 2001:1235::121 v2: remove the patch 1/3 of the v1 series (already included) use net_eq() add patch 1/4 and 2/4 ====================- Signed-off-by: David S.

2013-08-15ip6tnl: add x-netns supportNicolas Dichtel
This patch allows to switch the netns when packet is encapsulated or decapsulated. In other word, the encapsulated packet is received in a netns, where the lookup is done to find the tunnel. Once the tunnel is found, the packet is decapsulated and injecting into the corresponding interface which stands to another netns. When one of the two netns is removed, the tunnel is destroyed.

Commit cab70040dfd95ee32144f02fade64f0cb94f31a0 ("net: igmp: Reduce Unsolicited report interval to 1s when using IGMPv3") and 2690048c01f32bf45d1c1e1ab3079bc10ad2aea7 ("net: igmp: Allow user-space configuration of igmp unsolicited report interval") by William Manley made igmp unsolicited report intervals configurable per interface and corrected the interval of unsolicited igmpv3 report messages resendings to 1s. Same needs to be done for IPv6: MLDv1 (RFC2710 7.10.): 10 seconds MLDv2 (RFC3810 9.11.): 1 second Both intervals are configurable via new procfs knobs mldv1_unsolicited_report_interval and mldv2_unsolicited_report_interval. (also added .force_mld_version to ipv6_devconf_dflt to bring structs in line without semantic changes) v2: a) Joined documentation update for IPv4 and IPv6 MLD/IGMP unsolicited_report_interval procfs knobs. b) incorporate stylistic feedback from William Manley v3: a) add new DEVCONF_* values to the end of the enum (thanks to David Miller) Cc: Cong Wang <xiyou.wangcong@gmail.com> Cc: William Manley <william.manley@youview.com> Cc: Benjamin LaHaise <bcrl@kvack.org> Cc: YOSHIFUJI Hideaki <yoshfuji@linux-ipv6.org> Signed-off-by: Hannes Frederic Sowa <hannes@stressinduktion.org> Signed-off-by: David S.

2013-08-13tcp: reset reordering est. selectively on timeoutYuchung Cheng
On timeout the TCP sender unconditionally resets the estimated degree of network reordering (tp->reordering). The idea behind this is that the estimate is too large to trigger fast recovery (e.g., due to a IP path change). But for example if the sender only had 2 packets outstanding, then a timeout doesn't tell much about reordering. A sender that learns about reordering on big writes and loses packets on small writes will end up falsely retransmitting again and again, especially when reordering is more likely on big writes. Therefore the sender should only suspect that tp->reordering is too high if it could have gone into fast recovery with the (lower) default estimate.

2013-08-13gianfar: Add flow control supportClaudiu Manoil
eTSEC has Rx and Tx flow control capabilities that may be enabled through MACCFG1[Rx_Flow, Tx_Flow] bits. These bits must not be set however when eTSEC is operated in Half-Duplex mode. Unfortunately, the driver currently sets these bits unconditionally. This patch adds the proper handling of the PAUSE frame capability register bits by implementing the ethtool -A interface. When pause autoneg is enabled, the controller uses the phy's capability to negotiate PAUSE frame settings with the link partner and reconfigures its Rx_Flow and Tx_Flow settings to match the capabilities of the link partner. If pause autoneg is off, the PAUSE frame generation may be forced manually (ethtool -A). Flow control is disabled by default now. This implementation is inspired by the tg3 driver.

2013-08-10net: attempt high order allocations in sock_alloc_send_pskb()Eric Dumazet
Adding paged frags skbs to af_unix sockets introduced a performance regression on large sends because of additional page allocations, even if each skb could carry at least 100% more payload than before. We can instruct sock_alloc_send_pskb() to attempt high order allocations. Most of the time, it does a single page allocation instead of 8. I added an additional parameter to sock_alloc_send_pskb() to let other users to opt-in for this new feature on followup patches.

2013-08-10af_unix: improve STREAM behavior with fragmented memoryEric Dumazet
unix_stream_sendmsg() currently uses order-2 allocations, and we had numerous reports this can fail. The __GFP_REPEAT flag present in sock_alloc_send_pskb() is not helping. This patch extends the work done in commit eb6a24816b247c ("af_unix: reduce high order page allocations) for datagram sockets. This opens the possibility of zero copy IO (splice() and friends) The trick is to not use skb_pull() anymore in recvmsg() path, and instead add a @consumed field in UNIXCB() to track amount of already read payload in the skb. There is a performance regression for large sends because of extra page allocations that will be addressed in a follow-up patch, allowing sock_alloc_send_pskb() to attempt high order page allocations.

2013-08-09ath9k: use software queueing for multicast trafficFelix Fietkau
Create a per-vif dummy node entry for keeping the multicast software queues. This helps in setups with a lot of mulitcast traffic that could otherwise potentially drown out unicast traffic to stations. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W.

2013-08-09ath9k: use software queues for un-aggregated data packetsFelix Fietkau
This is a first step for improving fairness between legacy and 802.11n traffic, and it should also improve reliability of resets and channel changes by keeping the hardware queue depth very short. When an aggregation session is torn down, all packets in the retry queue will be removed from the BAW and freed. For all subframes that have not been transmitted yet, the A-MPDU flag will be cleared, and a sequence number allocated. This ensures that the next A-MPDU session will get the correct initial sequence number. This happens both on aggregation session start and stop.

2013-08-09ath9k: fix clearing expired A-MPDU subframes in tx completionFelix Fietkau
When the tid aggregation state has been marked as inactive, free completed tx packets immediately. When a new aggregation session has not been initialized yet, the BAW checks do not recognize it as expired. Might fix potential stalls in setting up a new aggregation session.

2013-08-09ath9k: fix block ack window tracking checkFelix Fietkau
When a packet has been tracked as part of the BlockAck window and added to the hardware queue, it can end up back in the TID queue again with fi->retries still set to 0 (e.g. if the frame was filtered). Keep an extra bit for the BAW tracking status to fix this corner case. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2013-08-09ath9k: simplify ath_tx_form_aggrFelix Fietkau
The check for ATH_AMPDU_SUBFRAME_DEFAULT is unnecessary, since it's set to half the maximum BlockAck Window size, which is already the maximum value that h_baw could possibly have. Also remove unnecessary variables. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
