RDMA/iwcm: Allow AFONLY binding for IPv6 addresses

2021-03-10T19:30:45+00:00

Binding IPv6 address/port to AF_INET6 domain only is provided via rdma_set_afonly(), but was not signalled to the provider. Applications like NFS/RDMA bind the same port to both IPv4 and IPv6 addresses simultaneously and thus rely on it working correctly.

RDMA/include: Replace license text with SPDX tags

2020-07-29T17:48:36+00:00

The header files in RDMA subsystem are dual licensed and can be described by simple SPDX tag, so replace all of them at once together with making them use the same coding style for header guard defines.

RDMA/IWPM: Support no port mapping requirements

2019-02-04T23:26:02+00:00

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.
