2019-04-22RDMA/mlx5: Allow inserting a steering rule to the FDBMark Bloch2-0/+2
Allow this only via mlx5 raw create flow API, legacy verbs are not supported. To accommodate that, we add a new attribute to matcher creation to indicate the type of flow table to be used. MLX5_IB_ATTR_FLOW_MATCHER_FT_TYPE With this new attribute MLX5_IB_ATTR_FLOW_MATCHER_FLOW_FLAGS is no longer needed, we keep it for compatibility but at most only a single attribute can be passed of the two. When inserting a flow rule to the FDB we require that a DEVX FT is provided as a destination, no other configuration is allowed.

Provide an option to change the net namespace of a rdma device through a netlink command. When multiple rdma devices exists in a system, and when containers are used, this will limit rdma device visibility to a specified net namespace. An example command to change net namespace of mlx5_1 device to the previously created net namespace 'foo' is: $ ip netns add foo $ rdma dev set mlx5_1 netns foo Signed-off-by: Parav Pandit <[email protected]> Signed-off-by: Jason Gunthorpe <[email protected]>
2019-04-18IB/mlx5: Fix scatter to CQE in DCT QP creationGuy Levi1-0/+1
When scatter to CQE is enabled on a DCT QP it corrupts the mailbox command since it tried to treat it as as QP create mailbox command instead of a DCT create command. The corrupted mailbox command causes userspace to malfunction as the device doesn't create the QP as expected. A new mlx5 capability is exposed to user-space which ensures that it will not enable the feature on DCT without this fix in the kernel.

Add netlink command that enables/disables sharing rdma device among multiple net namespaces. Using rdma tool, $rdma sys set netns shared (default mode) When rdma subsystem netns mode is set to shared mode, rdma devices will be accessible in all net namespaces. Using rdma tool, $rdma sys set netns exclusive When rdma subsystem netns mode is set to exclusive mode, devices will be accessible in only one net namespace at any given point of time. If there are any net namespaces other than default init_net exists, while executing this command, it will fail and mode cannot be changed. To change this mode, netlink command is used instead of sysctl, because netlink command allows to auto load a module.

2019-02-19RDMA/core: Add RDMA_NLDEV_CMD_NEWLINK/DELLINK supportSteve Wise1-2/+8
Add support for new LINK messages to allow adding and deleting rdma interfaces. This will be used initially for soft rdma drivers which instantiate device instances dynamically by the admin specifying a netdev device to use. The rdma_rxe module will be the first user of these messages. The design is modeled after RTNL_NEWLINK/DELLINK: rdma drivers register with the rdma core if they provide link add/delete functions. Each driver registers with a unique "type" string, that is used to dispatch messages coming from user space. A new RDMA_NLDEV_ATTR is defined for the "type" string. User mode will pass 3 attributes in a NEWLINK message: RDMA_NLDEV_ATTR_DEV_NAME for the desired rdma device name to be created, RDMA_NLDEV_ATTR_LINK_TYPE for the "type" of link being added, and RDMA_NLDEV_ATTR_NDEV_NAME for the net_device interface to use for this link. The DELLINK message will contain the RDMA_NLDEV_ATTR_DEV_INDEX of the device to delete.

2019-02-04RDMA/IWPM: Support no port mapping requirementsSteve Wise1-0/+24
A soft iwarp driver that uses the host TCP stack via a kernel mode socket does not need port mapping. In fact, if the port map daemon, iwpmd, is running, then iwpmd must not try and create/bind a socket to the actual port for a soft iwarp connection, since the driver already has that socket bound. Yet if the soft iwarp driver wants to interoperate with hard iwarp devices that -are- using port mapping, then the soft iwarp driver's mappings still need to be maintained and advertised by the iwpm protocol. This patch enhances the rdma driver<->iwcm interface to allow an iwarp driver to specify that it does not want port mapping. The iwpm kernel<->iwpmd interface is also enhanced to pass up this information on map requests. Care is taken to interoperate with the current iwpmd version (ABI version 3) and only use the new NL attributes if iwpmd supports ABI version 4. The ABI version define has also been created in rdma_netlink.h so both kernel and user code can share it. The iwcm and iwpmd negotiate the ABI version to use with a new HELLO netlink message.

Instead of sharing nl attribute enums for both request and response messages, we create separate enums for each IWPM message request and reply. This allows us to extend any given IWPM message by adding new attributes for just that message. These new enums are created, though, in a way to avoid breaking ABI version 3.

2018-09-17IB/rxe: Revise the ib_wr_opcode enumJason Gunthorpe1-1/+19
This enum has become part of the uABI, as both RXE and the ib_uverbs_post_send() command expect userspace to supply values from this enum. So it should be properly placed in include/uapi/rdma. In userspace this enum is called 'enum ibv_wr_opcode' as part of libibverbs.h. That enum defines different values for IB_WR_LOCAL_INV, IB_WR_SEND_WITH_INV, and IB_WR_LSO. These were introduced (incorrectly, it turns out) into libiberbs in 2015. The kernel has changed its mind on the numbering for several of the IB_WC values over the years, but has remained stable on IB_WR_LOCAL_INV and below. Based on this we can conclude that there is no real user space user of the values beyond IB_WR_ATOMIC_FETCH_AND_ADD, as they have never worked via rdma-core. This is confirmed by inspection, only rxe uses the kernel enum and implements the latter operations. rxe has clearly never worked with these attributes from userspace. Other drivers that support these opcodes implement the functionality without calling out to the kernel. To make IB_WR_SEND_WITH_INV and related work for RXE in userspace we choose to renumber the IB_WR enum in the kernel to match the uABI that userspace has bee using since before Soft RoCE was merged. This is an overall simpler configuration for the whole software stack, and obviously can't break anything existing.

2018-09-05RDMA/mlx5: Extend packet reformat verbsMark Bloch2-0/+4
We expose new actions: L2_TO_L2_TUNNEL - A generic encap from L2 to L2, the data passed should be the encapsulating headers. L3_TUNNEL_TO_L2 - Will do decap where the inner packet starts from L3, the data should be mac or mac + vlan (14 or 18 bytes). L2_TO_L3_TUNNEL - Will do encap where is L2 of the original packet will not be included, the data should be the encapsulating header.

2018-09-05RDMA/mlx5: Add new flow action verb - packet reformatMark Bloch2-0/+11
For now, only add L2_TUNNEL_TO_L2 option. This will allow to perform generic decap operation if the encapsulating protocol is L2 based, and the inner packet is also L2 based. For example this can be used to decap VXLAN packets.
