IB/mlx5: Return the administrative GUID if exists

2020-02-14T21:52:56Z

commit 4bbd4923d1f5627b0c47a9d7dfb5cc91224cfe0c upstream. A user can change the operational GUID (a.k.a affective GUID) through link/infiniband. Therefore it is preferred to return the currently set GUID if it exists instead of the operational. This way the PF can query which VF GUID will be set in the next bind. In order to align with MAC address, zero is returned if administrative GUID is not set. For example, before setting administrative GUID: $ ip link show ib0: mtu 4092 qdisc mq state UP mode DEFAULT group default qlen 256 link/infiniband 00:00:00:08:fe:80:00:00:00:00:00:00:52:54:00:c0:fe:12:34:55 brd 00:ff:ff:ff:ff:12:40:1b:ff:ff:00:00:00:00:00:00:ff:ff:ff:ff vf 0 link/infiniband 00:00:00:08:fe:80:00:00:00:00:00:00:52:54:00:c0:fe:12:34:55 brd 00:ff:ff:ff:ff:12:40:1b:ff:ff:00:00:00:00:00:00:ff:ff:ff:ff, spoof checking off, NODE_GUID 00:00:00:00:00:00:00:00, PORT_GUID 00:00:00:00:00:00:00:00, link-state auto, trust off, query_rss off Then: $ ip link set ib0 vf 0 node_guid 11:00:af:21:cb:05:11:00 $ ip link set ib0 vf 0 port_guid 22:11:af:21:cb:05:11:00 After setting administrative GUID: $ ip link show ib0: mtu 4092 qdisc mq state UP mode DEFAULT group default qlen 256 link/infiniband 00:00:00:08:fe:80:00:00:00:00:00:00:52:54:00:c0:fe:12:34:55 brd 00:ff:ff:ff:ff:12:40:1b:ff:ff:00:00:00:00:00:00:ff:ff:ff:ff vf 0 link/infiniband 00:00:00:08:fe:80:00:00:00:00:00:00:52:54:00:c0:fe:12:34:55 brd 00:ff:ff:ff:ff:12:40:1b:ff:ff:00:00:00:00:00:00:ff:ff:ff:ff, spoof checking off, NODE_GUID 11:00:af:21:cb:05:11:00, PORT_GUID 22:11:af:21:cb:05:11:00, link-state auto, trust off, query_rss off Fixes: 9c0015ef0928 ("IB/mlx5: Implement callbacks for getting VFs GUID attributes") Link: https://lore.kernel.org/r/20200116120048.12744-1-leon@kernel.org Signed-off-by: Danit Goldberg Signed-off-by: Leon Romanovsky Signed-off-by: Jason Gunthorpe Signed-off-by: Greg Kroah-Hartman

Danit Goldberg says: ==================== This series extends RTNETLINK to provide IB port and node GUIDs, which were configured for Infiniband VFs. The functionality to set VF GUIDs already existed for a long time, and here we are adding the missing "get" so that netlink will be symmetric and various cloud orchestration tools will be able to manage such VFs more naturally. The iproute2 was extended too to present those GUIDs. - ip link show For example: - ip link set ib4 vf 0 node_guid 22:44:33:00:33:11:00:33 - ip link set ib4 vf 0 port_guid 10:21:33:12:00:11:22:10 - ip link show ib4 ib4: mtu 4092 qdisc noop state DOWN mode DEFAULT group default qlen 256 link/infiniband 00:00:0a:2d:fe:80:00:00:00:00:00:00:ec:0d:9a:03:00:44:36:8d brd 00:ff:ff:ff:ff:12:40:1b:ff:ff:00:00:00:00:00:00:ff:ff:ff:ff vf 0 link/infiniband 00:00:0a:2d:fe:80:00:00:00:00:00:00:ec:0d:9a:03:00:44:36:8d brd 00:ff:ff:ff:ff:12:40:1b:ff:ff:00:00:00:00:00:00:ff:ff:ff:ff, spoof checking off, NODE_GUID 22:44:33:00:33:11:00:33, PORT_GUID 10:21:33:12:00:11:22:10, link-state disable, trust off, query_rss off ==================== Based on the mlx5-next branch from git://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux for dependencies * branch 'ib-guids': (35 commits) IB/mlx5: Implement callbacks for getting VFs GUID attributes IB/ipoib: Add ndo operation for getting VFs GUID attributes IB/core: Add interfaces to get VF node and port GUIDs net/core: Add support for getting VF GUIDs net/mlx5: Add new chain for netfilter flow table offload net/mlx5: Refactor creating fast path prio chains net/mlx5: Accumulate levels for chains prio namespaces net/mlx5: Define fdb tc levels per prio net/mlx5: Rename FDB_* tc related defines to FDB_TC_* defines net/mlx5: Simplify fdb chain and prio eswitch defines IB/mlx5: Load profile according to RoCE enablement state IB/mlx5: Rename profile and init methods net/mlx5: Handle "enable_roce" devlink param net/mlx5: Document flow_steering_mode devlink param devlink: Add new "enable_roce" generic device param net/mlx5: fix spelling mistake "metdata" -> "metadata" net/mlx5: fix kvfree of uninitialized pointer spec IB/mlx5: Introduce and use mlx5_core_is_vf() net/mlx5: E-switch, Enable metadata on own vport net/mlx5: Refactor ingress acl configuration ...

net/mlx5: Add new chain for netfilter flow table offload

2019-11-13T21:49:33Z

Netfilter tables (nftables) implements a software datapath that comes after tc ingress datapath. The datapath supports offloading such rules via the flow table offload API. This API is currently only used by NFT and it doesn't provide the global priority in regards to tc offload, so we assume offloading such rules must come after tc. It does provide a flow table priority parameter, so we need to provide some supported priority range. For that, split fastpath prio to two, flow table offload and tc offload, with one dedicated priority chain for flow table offload. Next patch will re-use the multi chain API to access this chain by allowing access to this chain by the fdb_sub_namespace.
