RDMA/IWPM: Support no port mapping requirements

2019-02-04T23:26:02Z

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.

RDMA/IWPM: refactor the IWPM message attribute names

2019-02-04T23:26:02Z

In order to add new IWPM_NL attributes, the enums for the IWPM commands attributes are refactored such that a new attribute can be added without breaking ABI version 3. 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.

RDMA/iwpm: Properly mark end of NL messages

2017-09-29T15:32:42Z

Commit 1a1c116f3dcf removes nlmsg_len calculation in ibnl_put_attr causing netlink messages to be rejected due to incorrect length. Add nlmsg_end after all attributes are appended to calculate the nlmsg_len.

RDMA/netlink: Rename and remove redundant parameter from ibnl_multicast

RDMA/iwcm: Remove extra EXPORT_SYMBOLS

RDMA/core: Add wait/retry version of ibnl_unicast

2017-08-09T13:08:27Z

Add a wait/retry version of ibnl_unicast, ibnl_unicast_wait, and modify ibnl_unicast to not wait/retry. This eliminates the undesirable wait for future users of ibnl_unicast. Change Portmapper calls originating from kernel to user-space to use ibnl_unicast_wait and take advantage of the wait/retry logic in netlink_unicast.
