2016-02-09bonding: 3ad: apply ad_actor settings changes immediatelyNikolay Aleksandrov3-3/+42
Currently the bonding allows to set ad_actor_system and prio while the bond device is down, but these are actually applied only if there aren't any slaves yet (applied to bond device when first slave shows up, and to slaves at 3ad bind time). After this patch changes are applied immediately and the new values can be used/seen after the bond's upped so it's not necessary anymore to release all and enslave again to see the changes.

Nikolay Borisov says: ==================== Namespaceify more of the tcp sysctl knobs This patch series continues making more of the tcp-related sysctl knobs be per net-namespace. Most of these apply per socket and have global defaults so should be safe and I don't expect any breakages. Having those per net-namespace is useful when multiple containers are hosted and it is required to tune the tcp settings for each independently of the host node. I've split the patches to be per-sysctl but after the review if the outcome is positive I'm happy to either send it in one big blob or just. ==================== Signed-off-by: David S.

2016-02-07virtio_net: add ethtool support for set and get of settingsNikolay Aleksandrov1-0/+60
This patch allows the user to set and retrieve speed and duplex of the virtio_net device via ethtool. Having this functionality is very helpful for simulating different environments and also enables the virtio_net device to participate in operations where proper speed and duplex are required (e.g. currently bonding lacp mode requires full duplex). Custom speed and duplex are not allowed, the user-supplied settings are validated before applying. Example: $ ethtool eth1 Settings for eth1: ... Speed: Unknown! Duplex: Unknown! (255) $ ethtool -s eth1 speed 1000 duplex full $ ethtool eth1 Settings for eth1: ... Speed: 1000Mb/s Duplex: Full Based on a patch by Roopa Prabhu.

Yuchung Cheng says: ==================== tcp: congestion control refactoring This patch set refactors the sequence of congestion control, loss recovery, and transmission logic in TCP ack processing. The design goal is to decouple and sequence them in the following order: 0. ACK accounting: free or tag sent packets [unchanged] 1. loss recovery: identify lost/ecn packets and update congestion state 2. congestion control: up/down cwnd and pacing rate based on (1) 3. transmission: send new or retransmit old based on (1) and (2) This refactoring makes the cwnd changes more clear because it's done in one place. The packet accounting is also more robust especially for connections that do not support SACK.

2016-02-07tcp: make congestion control more robust against reorderingYuchung Cheng1-1/+1
This change enables congestion control to update cwnd based on not only packet cumulatively acked but also packets delivered out-of-order. This makes congestion control robust against packet reordering because it may raise cwnd as long as packets are being delivered once reordering has been detected (i.e., it only cares the amount of packets delivered, not the ordering among them).

2016-02-07tcp: new delivery accountingYuchung Cheng2-6/+16
This patch changes the accounting of how many packets are newly acked or sacked when the sender receives an ACK. The current approach basically computes newly_acked_sacked = (prior_packets - prior_sacked) - (tp->packets_out - tp->sacked_out) where prior_packets and prior_sacked out are snapshot at the beginning of the ACK processing. The new approach tracks the delivery information via a new TCP state variable "delivered" which monotically increases as new packets are delivered in order or out-of-order. The reason for this change is that the current approach is brittle that produces negative or inaccurate estimate. 1) For non-SACK connections, an ACK that advances the SND.UNA could reset the DUPACK counters (tp->sacked_out) in tcp_process_loss() or tcp_fastretrans_alert(). This inflates the inflight suddenly and causes under-estimate or even negative estimate. Here is a real example: before after (processing ACK) packets_out 75 73 sacked_out 23 0 ca state Loss Open The old approach computes (75-23) - (73 - 0) = -21 delivered while the new approach computes 1 delivered since it considers the 2nd-24th packets are delivered OOO. 2) MSS change would re-count packets_out and sacked_out so the estimate is in-accurate and can even become negative. E.g., the inflight is doubled when MSS is halved. 3) Spurious retransmission signaled by DSACK is not accounted The new approach is simpler and more robust. For SACK connections, tp->delivered increments as packets are being acked or sacked in SACK and ACK processing. For non-sack connections, it's done in tcp_remove_reno_sacks() and tcp_add_reno_sack(). When an ACK advances the SND.UNA, tp->delivered is incremented by the number of packets ACKed (less the current number of DUPACKs received plus one packet hole). Upon receiving a DUPACK, tp->delivered is incremented assuming one out-of-order packet is delivered. Upon receiving a DSACK, tp->delivered is incremtened assuming one retransmission is delivered in tcp_sacktag_write_queue().

2016-02-07tcp: move cwnd reduction after recovery state procesingYuchung Cheng1-32/+28
Currently the cwnd is reduced and increased in various different places. The reduction happens in various places in the recovery state processing (tcp_fastretrans_alert) while the increase happens afterward. A better sequence is to identify lost packets and update the congestion control state (icsk_ca_state) first. Then base on the new state, up/down the cwnd in one central place. It's more clear to reason cwnd changes.

2016-02-07xen-netback: implement dynamic multicast controlPaul Durrant2-8/+82
My recent patch to the Xen Project documents a protocol for 'dynamic multicast control' in netif.h. This extends the previous multicast control protocol to not require a shared ring reconnection to turn the feature off. Instead the backend watches the "request-multicast-control" key in xenstore and turns the feature off if the key value is written to zero. This patch adds support for dynamic multicast control in xen-netback.

2016-02-07be2net: SRIOV Queue distribution should factor in EQ-count of VFsSriharsha Basavapatna2-9/+10
The SRIOV resource distribution logic for RX/TX queue counts is not optimal when a small number of VFs are enabled. It does not take into account the VF's EQ count while computing the queue counts. Because of this, the VF gets a large number of queues, though it doesn't have sufficient EQs, resulting in wasted queue resources. And the PF gets a smaller share of queues though it has more EQs.
