Get originating device from tuple offload metadata match ingress_ifindex, and set flow_source hint to either LOCAL for vf/sf reps, UPLINK for uplink/wire/tunnel devices/bond, or ANY (as before this patch) for all others. This allows lower layer (software steering or firmware) to insert the tuple rule only in one table (either rx or tx) instead of two (rx and tx). Signed-off-by:

Driver offloading ct tuples can use the information of which devices received the packets that created the offloaded connections, to more efficiently offload them only to the relevant device. Add new act_ct nf conntrack extension, which is used to store the skb devices before offloading the connection, and then fill in the tuple iifindex so drivers can get the device via metadata dissector match.

Use dma_set_mask_and_coherent() instead of unrolling it with some dma_set_mask()+dma_set_coherent_mask(). Moreover, as stated in [1], dma_set_mask() with a 64-bit mask will never fail if dev->dma_mask is non-NULL. So, if it fails, the 32 bits case will also fail for the same reason. That said, 'high_dma' can only be 1 after a successful dma_set_mask_and_coherent(). Simplify code and remove some dead code accordingly, including a now useless parameter to vxge_device_register().

Colin Foster says: ==================== lynx pcs interface cleanup The current Felix driver (and Seville) rely directly on the lynx_pcs device. There are other possible PCS interfaces that can be used with this hardware, so this should be abstracted from felix. The generic phylink_pcs is used instead. While going through the code, there were some opportunities to change some misleading variable names. Those are included in this patch set. v1->v2 * compile-time fixes for freescale parts ==================== Signed-off-by: -

v3: - Report 'backlog' (bytes) instead of 'qlen' (number of packets) v2: - Fix sparse warning (use rcu_dereference) This patch adds support for the queue depth in IOAM trace data fields. The draft [1] says the following: The "queue depth" field is a 4-octet unsigned integer field. This field indicates the current length of the egress interface queue of the interface from where the packet is forwarded out. The queue depth is expressed as the current amount of memory buffers used by the queue (a packet could consume one or more memory buffers, depending on its size). An existing function (i.e., qdisc_qstats_qlen_backlog) is used to retrieve the current queue length without reinventing the wheel. Note: it was tested and qlen is increasing when an artificial delay is added on the egress with tc. [1] https://datatracker.ietf.org/doc/html/draft-ietf-ippm-ioam-data#section-5.4.2.7Signed-off-by:

This implements TCP ULP for SMC, helps applications to replace TCP with SMC protocol in place. And we use it to implement transparent replacement. This replaces original TCP sockets with SMC, reuse TCP as clcsock when calling setsockopt with TCP_ULP option, and without any overhead. To replace TCP sockets with SMC, there are two approaches: - use setsockopt() syscall with TCP_ULP option, if error, it would fallback to TCP. - use BPF prog with types BPF_CGROUP_INET_SOCK_CREATE or others to replace transparently. BPF hooks some points in create socket, bind and others, users can inject their BPF logics without modifying their applications, and choose which connections should be replaced with SMC by calling setsockopt() in BPF prog, based on rules, such as TCP tuples, PID, cgroup, etc... BPF doesn't support calling setsockopt with TCP_ULP now, I will send the patches after this accepted. Signed-off-by:

Tony Lu says: ==================== RDMA device net namespace support for SMC This patch set introduces net namespace support for linkgroups. Path 1 is the main approach to implement net ns support. Path 2 - 4 are the additional modifications to let us know the netns. Also, I will submit changes of smc-tools to github later. Currently, smc doesn't support net namespace isolation. The ibdevs registered to smc are shared for all linkgroups and connections. When running applications in different net namespaces, such as container environment, applications should only use the ibdevs that belongs to the same net namespace. This adds a new field, net, in smc linkgroup struct. During first contact, it checks and find the linkgroup has same net namespace, if not, it is going to create and initialized the net field with first link's ibdev net namespace. When finding the rdma devices, it also checks the sk net device's and ibdev's net namespaces. After net namespace destroyed, the net device and ibdev move to root net namespace, linkgroups won't be matched, and wait for lgr free. If rdma net namespace exclusive mode is not enabled, it behaves as before. Steps to enable and test net namespaces: 1. enable RDMA device net namespace exclusive support rdma system set netns exclusive # default is shared 2. create new net namespace, move and initialize them ip netns add test1 rdma dev set mlx5_1 netns test1 ip link set dev eth2 netns test1 ip netns exec test1 ip link set eth2 up ip netns exec test1 ip addr add ${HOST_IP}/26 dev eth2 3. setup server and client, connect N <-> M ip netns exec test1 smc_run sockperf server --tcp # server ip netns exec test1 smc_run sockperf pp --tcp -i ${SERVER_IP} # client 4. netns isolated linkgroups (2 * 2 mesh) with their own linkgroups - server LG-ID LG-Role LG-Type VLAN #Conns PNET-ID 00000100 SERV SINGLE 0 0 00000200 SERV SINGLE 0 0 00000300 SERV SINGLE 0 0 00000400 SERV SINGLE 0 0 - client LG-ID LG-Role LG-Type VLAN #Conns PNET-ID 00000100 CLNT SINGLE 0 0 00000200 CLNT SINGLE 0 0 00000300 CLNT SINGLE 0 0 00000400 CLNT SINGLE 0 0 ==================== Signed-off-by: -

Currently, rdma device supports exclusive net namespace isolation, however linkgroup doesn't know and support ibdev net namespace. Applications in the containers don't want to share the nics if we enabled rdma exclusive mode. Every net namespaces should have their own linkgroups. This patch introduce a new field net for linkgroup, which is standing for the ibdev net namespace in the linkgroup. The net in linkgroup is initialized with the net namespace of link's ibdev. It compares the net of linkgroup and sock or ibdev before choose it, if no matched, create new one in current net namespace. If rdma net namespace exclusive mode is not enabled, it behaves as before.
