IB/core: Add get FW version string to the core

2016-06-23T16:08:33Z

Allow for a common core function to get firmware version strings from the individual devices. In later patches this format can then then be used to pass a properly formated version string through the IPoIB layer. The problem with the current code in the IPoIB layer is that it is specific to certain hardware types. Furthermore, this gives us a common function through which the core can provide a common sysfs entry. Eventually we may want to remove the sysfs export but this provides for user space backwards compatibility. Reviewed-by: Dennis Dalessandro Signed-off-by: Ira Weiny Signed-off-by: Doug Ledford

IB/core: Fix query port failure in RoCE

2016-06-07T13:50:52Z

Currently ib_query_port always attempts to to read the subnet prefix by calling ib_query_gid(). For RoCE/iWARP there is no subnet manager and no subnet prefix. Fix this by querying GID[0] only for IB networks.

IB/core: fix an error code in ib_core_init()

2016-06-06T23:19:07Z

We should return the error code if ib_add_ibnl_clients() fails. The current code returns success. Fixes: 735c631ae99d ('IB/core: Register SA ibnl client during ib_core initialization') Signed-off-by: Dan Carpenter Reviewed-by: Mark Bloch Signed-off-by: Doug Ledford

IB/core: Add IP to GID netlink offload

2016-05-24T18:44:04Z

There is an assumption that rdmacm is used only between nodes in the same IB subnet, this why ARP resolution can be used to turn IP to GID in rdmacm. When dealing with IB communication between subnets this assumption is no longer valid. ARP resolution will get us the next hop device address and not the peer node's device address. To solve this issue, we will check user space if it can provide the GID of the peer node, and fail if not. We add a sequence number to identify each request and fill in the GID upon answer from userspace. Signed-off-by: Mark Bloch Signed-off-by: Doug Ledford

IB/core: Register SA ibnl client during ib_core initialization

2016-05-24T18:43:43Z

Move SA ibnl client registration to ib_core module init. This will allow us to register a single client to handle all RDMA_NL_LS operations and make it SA independent. Signed-off-by: Mark Bloch Signed-off-by: Doug Ledford

IB/core: Integrate IB address resolution module into core

2016-05-24T18:40:13Z

IB address resolution is declared as a module (ib_addr.ko) which loads itself before IB core module (ib_core.ko). It causes to the scenario where IB netlink which is initialized by IB core can't be used by ib_addr.ko. In order to solve it, we are converting ib_addr.ko to be part of IB core module.

IB/core: Add subnet prefix to port info

2016-03-21T20:34:06Z

The subnet prefix is a part of the port_info MAD returned and should be available at the ib_port_attr struct. We define it here and provide a default implementation in case the hardware driver does not provide one. The subnet prefix is required when creating the address vector to access the SA in networks where GRH must be used. Signed-off-by: Eli Cohen Reviewed-by: Or Gerlitz Signed-off-by: Doug Ledford
