Jiri Pirko says: ==================== net: return offloaded stats as default and expose original sw stats The problem we try to handle is about offloaded forwarded packets which are not seen by kernel. Let me try to draw it: port1 port2 (HW stats are counted here) \ / \ / \ / --(A)---- ASIC --(B)-- | (C) | CPU (SW stats are counted here) Now we have couple of flows for TX and RX (direction does not matter here): 1) port1->A->ASIC->C->CPU For this flow, HW and SW stats are equal. 2) port1->A->ASIC->C->CPU->C->ASIC->B->port2 For this flow, HW and SW stats are equal. 3) port1->A->ASIC->B->port2 For this flow, SW stats are 0. The purpose of this patchset is to provide facility for user to find out the difference between flows 1+2 and 3. In other words, user will be able to see the statistics for the slow-path (through kernel). Also note that HW stats are what someone calls "accumulated" stats. Every packet counted by SW is also counted by HW. Not the other way around. As a default the accumulated stats (HW) will be exposed to user so the userspace apps can react properly. This patchset add the SW stats (flows 1+2) under offload related stats, so in the future we can expose other offload related stat in a similar way. --- v9->v10: - patch 2/3 - removed unnecessary ()s as pointed out by Nik v8->v9: - patch 2/3 - add using of idxattr and prividx v7->v8: - patch 2/3 - move helping const from uapi to rtnetlink - cancel driver xstat nesting if it is empty v6->v7: - patch 1/3: - ndo interface changed to get the wanted stats type as an input. - change commit message. - patch 2/3: - create a nesting for offloaded stat and put SW stats under it. - change the ndo call to indicate which offload stats we wants. - change commit message. - patch 3/3: - change ndo implementation to match the changes in the previous patches. - change commit message. v5->v6: - patch 2/4 was dropped as requested by Roopa - patch 1/3: - comment changed to indicate that default stats are combined stats - commit massage changed - patch 2/3: (previously 3/4) - SW stats return nothing if there is no SW stats ndo v4->v5: - updated cover letter - patch3/4: - using memcpy directly to copy stats as requested by DaveM v3->v4: - patch1/4: - fixed "return ()" pointed out by EricD - patch2/4: - fixed if_nlmsg_size as pointed out by EricD v2->v3: - patch1/4: - added dev_have_sw_stats helper - patch2/4: - avoided memcpy as requested by DaveM - patch3/4: - use new dev_have_sw_stats helper v1->v2: - patch3/4: - fixed NULL initialization ==================== Signed-off-by: NDavid S.

Instead of using flow stats per NUMA node, use it per CPU. When using megaflows, the stats lock can be a bottleneck in scalability. On a E5-2690 12-core system, usual throughput went from ~4Mpps to ~15Mpps when forwarding between two 40GbE ports with a single flow configured on the datapath. This has been tested on a system with possible CPUs 0-7,16-23. After module removal, there were no corruption on the slab cache.

As David and Marcelo's suggestion, ENOMEM err shouldn't return back to user in transmit path. Instead, sctp's retransmit would take care of the chunks that fail to send because of ENOMEM. This patch is only to do some release job when alloc_skb fails, not to return ENOMEM back any more. Besides, it also cleans up sctp_packet_transmit's err path, and fixes some issues in err path: - It didn't free the head skb in nomem: path. - No need to check nskb in no_route: path. - It should goto err: path if alloc_skb fails for head. - Not all the NOMEMs should free nskb.

Every time when sctp calls sctp_outq_flush, it sends out the chunks of control queue, retransmit queue and data queue. Even if some trunks are failed to transmit, it still has to flush all the transports, as it's the only chance to clean that transmit_list. So the latest transmit error here should be returned back. This transmit error is an internal error of sctp stack. I checked all the places where it uses the transmit error (the return value of sctp_outq_flush), most of them are actually just save it to sk_err. Except for sctp_assoc/endpoint_bh_rcv, they will drop the chunk if it's failed to send a REPLY, which is actually incorrect, as we can't be sure the error that sctp_outq_flush returns is from sending that REPLY. So it's meaningless for sctp_outq_flush to return error back. This patch is to save transmit error to sk_err in sctp_outq_flush, the new error can update the old value. Eventually, sctp_wait_for_* would check for it. Signed-off-by: NXin Long <lucien.xin@gmail.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Last patch "sctp: do not return the transmit err back to sctp_sendmsg" made sctp_primitive_SEND return err only when asoc state is unavailable. In this case, chunks are not enqueued, they have no chance to be freed if we don't take care of them later. This Patch is actually to revert commit 1cd4d5c4 ("sctp: remove the unused sctp_datamsg_free()"), commit 69b5777f ("sctp: hold the chunks only after the chunk is enqueued in outq") and commit 8b570dc9 ("sctp: only drop the reference on the datamsg after sending a msg"), to use sctp_datamsg_free to free the chunks of current msg.

Once a chunk is enqueued successfully, sctp queues can take care of it. Even if it is failed to transmit (like because of nomem), it should be put into retransmit queue. If sctp report this error to users, it confuses them, they may resend that msg, but actually in kernel sctp stack is in charge of retransmit it already. Besides, this error probably is not from the failure of transmitting current msg, but transmitting or retransmitting another msg's chunks, as sctp_outq_flush just tries to send out all transports' chunks.

Data Chunks are only sent by sctp_primitive_SEND, in which sctp checks the asoc's state through statetable before calling sctp_outq_tail. So there's no need to check the asoc's state again in sctp_outq_tail. Besides, sctp_do_sm is protected by lock_sock, even if sending msg is interrupted by timer events, the event's processes still need to acquire lock_sock first. It means no others CMDs can be enqueue into side effect list before CMD_SEND_MSG to change asoc->state, so it's safe to remove it. This patch is to remove redundant asoc->state check from sctp_outq_tail. Signed-off-by: NXin Long <lucien.xin@gmail.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

the test creates 3 namespaces with veth connected via bridge. First two namespaces simulate two different hosts with the same IPv4 and IPv6 addresses configured on the tunnel interface and they communicate with outside world via standard tunnels. Third namespace creates collect_md tunnel that is driven by BPF program which selects different remote host (either first or second namespace) based on tcp dest port number while tcp dst ip is the same. This scenario is rough approximation of load balancer use case. The tests check both traditional tunnel configuration and collect_md mode.

With large BDP TCP flows and lossy networks, it is very important to keep a low number of skbs in the write queue. RACK and SACK processing can perform a linear scan of it. We should avoid putting any payload in skb->head, so that SACK shifting can be done if needed. With this patch, we allow to pack ~0.5 MB per skb instead of the 64KB initially cooked at tcp_sendmsg() time. This gives a reduction of number of skbs in write queue by eight. tcp_rack_detect_loss() likes this. We still allow payload in skb->head for first skb put in the queue, to not impact RPC workloads.

To improve the memory consumption scheme, we omit the flow that demands and splits high-order pages in Striding RQ, and stay with a single Striding RQ flow that uses order-0 pages. Moving to fragmented memory allows the use of larger MPWQEs, which reduces the number of UMR posts and filler CQEs. Moving to a single flow allows several optimizations that improve performance, especially in production servers where we would anyway fallback to order-0 allocations: - inline functions that were called via function pointers. - improve the UMR post process. This patch alone is expected to give a slight performance reduction. However, the new memory scheme gives the possibility to use a page-cache of a fair size, that doesn't inflate the memory footprint, which will dramatically fix the reduction and even give a performance gain.

This means that mac80211 doesn't look at frames anymore but rather relies on a notification that will come from the device when a PS transition occurs or when a PS-Poll / trigger frame is detected by the device. iwlwifi will need this capability but still needs mac80211 to take care of the TIM IE. Today, if a driver sets AP_LINK_PS, mac80211 will not update the TIM IE. Change mac80211 to check existence of the set_tim driver callback rather than using AP_LINK_PS to decide if the driver handles the TIM IE internally or not.

John Crispin says: ==================== net-next: dsa: add QCA8K support This series is based on the AR8xxx series posted by Matthieu Olivari in may 2015. The following changes were made since then * fixed the nitpicks from the previous review * updated to latest API * turned it into an mdio device * added callbacks for fdb, bridge offloading, stp, eee, port status * fixed several minor issues to the port setup and arp learning * changed the namespacing as this driver to qca8k The driver has so far only been tested on qca8337/N. It should work on other QCA switches such as the qca8327 with minor changes. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>
