Unlike ipv4 code here it's possible to reuse ip6_tnl_xmit() function for both collect_md and traditional tunnels. bpf_skb_[gs]et_tunnel_key() helpers and ovs (in the future) are the users.

Similar to gre, vxlan, geneve tunnels allow IPIP tunnels to operate in 'collect metadata' mode. bpf_skb_[gs]et_tunnel_key() helpers can make use of it right away. ovs can use it as well in the future (once appropriate ovs-vport abstractions and user apis are added). Note that just like in other tunnels we cannot cache the dst, since tunnel_info metadata can be different for every packet.

2016-09-17tcp: prepare skbs for better sack shiftingEric Dumazet1-7/+24
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.

Tariq Toukan says: ==================== mlx5e Order-0 pages for Striding RQ In this series, we refactor our Striding RQ receive-flow to always use fragmented WQEs (Work Queue Elements) using order-0 pages, omitting the flow that allocates and splits high-order pages which would fragment and deplete high-order pages in the system. The first patch gives a slight degradation, but opens the opportunity to using a simple page-cache mechanism of a fair size. The page-cache, implemented in patch 3, not only closes the performance gap but even gives a gain. In patch 2 we re-organize the code to better manage the calls for alloc/de-alloc pages in the RX flow.

2016-09-17net/mlx5e: Single flow order-0 pages for Striding RQTariq Toukan5-304/+184
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. Performance tests: The following results were measured on a freshly booted system, giving optimal baseline performance, as high-order pages are yet to be fragmented and depleted.

2016-09-16tcp: fix a stale ooo_last_skb after a replaceEric Dumazet1-1/+2
When skb replaces another one in ooo queue, I forgot to also update tp->ooo_last_skb as well, if the replaced skb was the last one in the queue. To fix this, we simply can re-use the code that runs after an insertion, trying to merge skbs at the right of current skb. This not only fixes the bug, but also remove all small skbs that might be a subset of the new one. Example: We receive segments 2001:3001, 4001:5001 Then we receive 2001:8001 : We should replace 2001:3001 with the big skb, but also remove 4001:50001 from the queue to save space. packetdrill test demonstrating the bug 0.000 socket(..., SOCK_STREAM, IPPROTO_TCP) = 3 +0 setsockopt(3, SOL_SOCKET, SO_REUSEADDR, [1], 4) = 0 +0 bind(3, ..., ...) = 0 +0 listen(3, 1) = 0 +0 < S 0:0(0) win 32792 <mss 1000,sackOK,nop,nop,nop,wscale 7> +0 > S. 0:0(0) ack 1 <mss 1460,nop,nop,sackOK,nop,wscale 7> +0.100 < . 1:1(0) ack 1 win 1024 +0 accept(3, ..., ...) = 4 +0.01 < . 1001:2001(1000) ack 1 win 1024 +0 > . 1:1(0) ack 1 <nop,nop, sack 1001:2001> +0.01 < . 1001:3001(2000) ack 1 win 1024 +0 > . 1:1(0) ack 1 <nop,nop, sack 1001:2001 1001:3001> Fixes: 9f5afeae5152 ("tcp: use an RB tree for ooo receive queue") Signed-off-by: Eric Dumazet <edumazet@google.com> Reported-by: Yuchung Cheng <ycheng@google.com> Cc: Yaogong Wang <wygivan@google.com> Signed-off-by: David S.

There are a couple of points of note: (1) There is one non-fix patch that adjusts the call ref tracking tracepoint to make kernel API-held refs on calls more obvious. This is a prerequisite for the patch that fixes prealloc refcounting. (2) The final patch alters how jumbo packets that partially exceed the receive window are handled. Previously, space was being left in the Rx buffer for them, but this significantly hurts performance as the Rx window can't be increased to match the OpenAFS Tx window size. Instead, the excess subpackets are discarded and an EXCEEDS_WINDOW ACK is generated for the first. To avoid the problem of someone trying to run the kernel out of space by feeding the kernel a series of overlapping maximal jumbo packets, we stop allowing jumbo packets on a call if we encounter more than three jumbo packets with duplicate or excessive subpackets. ==================== Reviewed-by: Steve Wise <swise@opengridcomputing.com> Signed-off-by: David S.

2016-09-16openvswitch: avoid deferred execution of recirc actionsLance Richardson1-2/+28
The ovs kernel data path currently defers the execution of all recirc actions until stack utilization is at a minimum. This is too limiting for some packet forwarding scenarios due to the small size of the deferred action FIFO (10 entries). For example, broadcast traffic sent out more than 10 ports with recirculation results in packet drops when the deferred action FIFO becomes full, as reported here: http://openvswitch.org/pipermail/dev/2016-March/067672.html Since the current recursion depth is available (it is already tracked by the exec_actions_level pcpu variable), we can use it to determine whether to execute recirculation actions immediately (safe when recursion depth is low) or defer execution until more stack space is available. With this change, the deferred action fifo size becomes a non-issue for currently failing scenarios because it is no longer used when there are three or fewer recursions through ovs_execute_actions().

Or Gerlitz says: ==================== net/sched: cls_flower: Add ports masks This series adds the ability to specify tcp/udp ports masks for TC/flower filter matches. I also removed an unused fields from the flower keys struct and clarified the format of the recently added vlan attibutes. v1--> v2 changes: * fixes typo in patch #2 title and change log (Sergei) * added acks provided by Jiri on v1 FWIW, by mistake the cover letter of V1 (but not the patches) carried V2 tag, hope this doesn't create too much confusion. ==================== Signed-off-by: David S.
