2023-05-23gve: Support IPv6 Big TCP on DQCoco Li
Add support for using IPv6 Big TCP on DQ which can handle large TSO/GRO packets. See https://lwn.net/Articles/895398/. This can improve the throughput and CPU usage. Perf test result: ip -d link show $DEV gso_max_size 185000 gso_max_segs 65535 tso_max_size 262143 tso_max_segs 65535 gro_max_size 185000 For performance, tested with neper using 9k MTU on hardware that supports 200Gb/s line rate. In single streams when line rate is not saturated, we expect throughput improvements. When the networking is performing at line rate, we expect cpu usage improvements. Tcp_stream (unidirectional stream test, T=thread, F=flow): skb=180kb, T=1, F=1, no zerocopy: throughput average=64576.88 Mb/s, sender stime=8.3, receiver stime=10.68 skb=64kb, T=1, F=1, no zerocopy: throughput average=64862.54 Mb/s, sender stime=9.96, receiver stime=12.67 skb=180kb, T=1, F=1, yes zerocopy: throughput average=146604.97 Mb/s, sender stime=10.61, receiver stime=5.52 skb=64kb, T=1, F=1, yes zerocopy: throughput average=131357.78 Mb/s, sender stime=12.11, receiver stime=12.25 skb=180kb, T=20, F=100, no zerocopy: throughput average=182411.37 Mb/s, sender stime=41.62, receiver stime=79.4 skb=64kb, T=20, F=100, no zerocopy: throughput average=182892.02 Mb/s, sender stime=57.39, receiver stime=72.69 skb=180kb, T=20, F=100, yes zerocopy: throughput average=182337.65 Mb/s, sender stime=27.94, receiver stime=39.7 skb=64kb, T=20, F=100, yes zerocopy: throughput average=182144.20 Mb/s, sender stime=47.06, receiver stime=39.01 Signed-off-by: Ziwei Xiao <ziweixiao@google.com> Signed-off-by: Coco Li <lixiaoyan@google.com> Reviewed-by: Simon Horman <simon.horman@corigine.com> Link: https://lore.kernel.org/r/20230522201552.3585421-1-ziweixiao@google.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2023-05-23Merge branch 'splice-net-replace-sendpage-with-sendmsg-msg_splice_pages-part-1'Jakub Kicinski
David Howells says: ==================== splice, net: Replace sendpage with sendmsg(MSG_SPLICE_PAGES), part 1 Here's the first tranche of patches towards providing a MSG_SPLICE_PAGES internal sendmsg flag that is intended to replace the ->sendpage() op with calls to sendmsg(). MSG_SPLICE_PAGES is a hint that tells the protocol that it should splice the pages supplied if it can and copy them if not. This will allow splice to pass multiple pages in a single call and allow certain parts of higher protocols (e.g. sunrpc, iwarp) to pass an entire message in one go rather than having to send them piecemeal. This should also make it easier to handle the splicing of multipage folios. A helper, skb_splice_from_iter() is provided to do the work of splicing or copying data from an iterator. If a page is determined to be unspliceable (such as being in the slab), then the helper will give an error. Note that this facility is not made available to userspace and does not provide any sort of callback. This set consists of the following parts: (1) Define the MSG_SPLICE_PAGES flag and prevent sys_sendmsg() from being able to set it. (2) Add an extra argument to skb_append_pagefrags() so that something other than MAX_SKB_FRAGS can be used (sysctl_max_skb_frags for example). (3) Add the skb_splice_from_iter() helper to handle splicing pages into skbuffs for MSG_SPLICE_PAGES that can be shared by TCP, IP/UDP and AF_UNIX. (4) Implement MSG_SPLICE_PAGES support in TCP. (5) Make do_tcp_sendpages() just wrap sendmsg() and then fold it in to its various callers. (6) Implement MSG_SPLICE_PAGES support in IP and make udp_sendpage() just a wrapper around sendmsg(). (7) Implement MSG_SPLICE_PAGES support in IP6/UDP6. (8) Implement MSG_SPLICE_PAGES support in AF_UNIX. (9) Make AF_UNIX copy unspliceable pages.

2023-05-23nfp: add L4 RSS hashing on UDP trafficJaco Coetzee
Add layer 4 RSS hashing on UDP traffic to allow for the utilization of multiple queues for multiple connections on the same IP address. Previously, since the introduction of the driver, RSS hashing was only performed on the source and destination IP addresses of UDP packets thereby limiting UDP traffic to a single queue for multiple connections on the same IP address. The transport layer is now included in RSS hashing for UDP traffic, which was not previously the case. The reason behind the previous limitation is unclear - either a historic limitation of the NFP device, or an oversight.

Without matching on a meta data values slow path works based on VF's MAC addresses. It causes a problem when the VF wants to use more than one MAC address (e.g. when it is in trusted mode). Parse all meta data in the same place where protocol type fields are parsed. Add description for the currently implemented meta data. It is important to note that depending on DDP not all described meta data can be available.

2023-05-19ice: use src VSI instead of src MAC in slow-pathMichal Swiatkowski
The use of a source MAC to direct packets from the VF to the corresponding port representor is only ok if there is only one MAC on a VF. To support this functionality when the number of MACs on a VF is greater, it is necessary to match a source VSI instead of a source MAC. Let's use the new switch API that allows matching on metadata. If MAC isn't used in match criteria there is no need to handle adding rule after virtchnl command. Instead add new rule while port representor is being configured. Remove rule_added field, checking for sp_rule can be used instead. Remove also checking for switchdev running in deleting rule as it can be called from unroll context when running flag isn't set. Checking for sp_rule covers both context (with and without running flag). Rules are added in eswitch configuration flow, so there is no need to have replay function.

2023-05-19ice: allow matching on meta dataMichal Swiatkowski
Add meta data matching criteria in the same place as protocol matching criteria. There is no need to add meta data as special words after parsing all lookups. Trade meta data in the same why as other lookups. The one difference between meta data lookups and protocol lookups is that meta data doesn't impact how the packets looks like. Because of that ignore it when filling testing packet. Match on tunnel type meta data always if tunnel type is different than TNL_LAST.
