rdma_accept - Called to accept a connection request or response. : Connection identifier associated with the request. : Information needed to establish the connection. This must be provided if accepting a connection request. If accepting a connection response, this parameter must be NULL.
Typically, this routine is only called by the listener to accept a connection request. It must also be called on the active side of a connection if the user is performing their own QP transitions.
In the case of error, a reject message is sent to the remote side and the state of the qp associated with the id is modified to error, such that any previously posted receive buffers would be flushed.
| int rdma_bind_addr | ( | struct rdma_cm_id * | id, |
| struct sockaddr * | addr | ||
| ) |
rdma_bind_addr - Bind an RDMA identifier to a source address and associated RDMA device, if needed.
: RDMA identifier. : Local address information. Wildcard values are permitted.
This associates a source address with the RDMA identifier before calling rdma_listen. If a specific local address is given, the RDMA identifier will be bound to a local RDMA device.
| int rdma_connect | ( | struct rdma_cm_id * | id, |
| struct rdma_conn_param * | conn_param | ||
| ) |
rdma_connect - Initiate an active connection request. : Connection identifier to connect. : Connection information used for connected QPs.
Users must have resolved a route for the rdma_cm_id to connect with by having called rdma_resolve_route before calling this routine.
This call will either connect to a remote QP or obtain remote QP information for unconnected rdma_cm_id's. The actual operation is based on the rdma_cm_id's port space.

| int rdma_create_qp | ( | struct rdma_cm_id * | id, |
| struct ib_pd * | pd, | ||
| struct ib_qp_init_attr * | qp_init_attr | ||
| ) |
rdma_create_qp - Allocate a QP and associate it with the specified RDMA identifier.
QPs allocated to an rdma_cm_id will automatically be transitioned by the CMA through their states.
| void rdma_destroy_id | ( | struct rdma_cm_id * | id | ) |
| void rdma_destroy_qp | ( | struct rdma_cm_id * | id | ) |
| int rdma_disconnect | ( | struct rdma_cm_id * | id | ) |
| int rdma_init_qp_attr | ( | struct rdma_cm_id * | id, |
| struct ib_qp_attr * | qp_attr, | ||
| int * | qp_attr_mask | ||
| ) |
rdma_init_qp_attr - Initializes the QP attributes for use in transitioning to a specified QP state. : Communication identifier associated with the QP attributes to initialize. : On input, specifies the desired QP state. On output, the mandatory and desired optional attributes will be set in order to modify the QP to the specified state. : The QP attribute mask that may be used to transition the QP to the specified state.
Users must set the ->qp_state to the desired QP state. This call will set all required attributes for the given transition, along with known optional attributes. Users may override the attributes returned from this call before calling ib_modify_qp.
Users that wish to have their QP automatically transitioned through its states can associate a QP with the rdma_cm_id by calling rdma_create_qp().
rdma_join_multicast - Join the multicast group specified by the given address. : Communication identifier associated with the request. : Multicast address identifying the group to join. : User-defined context associated with the join request, returned to the user through the private_data pointer in multicast events.
| void rdma_leave_multicast | ( | struct rdma_cm_id * | id, |
| struct sockaddr * | addr | ||
| ) |
| int rdma_listen | ( | struct rdma_cm_id * | id, |
| int | backlog | ||
| ) |
rdma_listen - This function is called by the passive side to listen for incoming connection requests.
Users must have bound the rdma_cm_id to a local address by calling rdma_bind_addr before calling this routine.
| int rdma_notify | ( | struct rdma_cm_id * | id, |
| enum ib_event_type | event | ||
| ) |
rdma_notify - Notifies the RDMA CM of an asynchronous event that has occurred on the connection. : Connection identifier to transition to established. : Asynchronous event.
This routine should be invoked by users to notify the CM of relevant communication events. Events that should be reported to the CM and when to report them are:
IB_EVENT_COMM_EST - Used when a message is received on a connected QP before an RTU has been received.
| int rdma_resolve_addr | ( | struct rdma_cm_id * | id, |
| struct sockaddr * | src_addr, | ||
| struct sockaddr * | dst_addr, | ||
| int | timeout_ms | ||
| ) |
rdma_resolve_addr - Resolve destination and optional source addresses from IP addresses to an RDMA address. If successful, the specified rdma_cm_id will be bound to a local device.
: RDMA identifier. : Source address information. This parameter may be NULL. : Destination address information. : Time to wait for resolution to complete.
| int rdma_resolve_route | ( | struct rdma_cm_id * | id, |
| int | timeout_ms | ||
| ) |
rdma_resolve_route - Resolve the RDMA address bound to the RDMA identifier into route information needed to establish a connection.
This is called on the client side of a connection. Users must have first called rdma_resolve_addr to resolve a dst_addr into an RDMA address before calling this routine.
| int rdma_set_afonly | ( | struct rdma_cm_id * | id, |
| int | afonly | ||
| ) |
| int rdma_set_reuseaddr | ( | struct rdma_cm_id * | id, |
| int | reuse | ||
| ) |
| void rdma_set_service_type | ( | struct rdma_cm_id * | id, |
| int | tos | ||
| ) |
rdma_set_service_type - Set the type of service associated with a connection identifier. : Communication identifier to associated with service type. : Type of service.
The type of service is interpretted as a differentiated service field (RFC 2474). The service type should be specified before performing route resolution, as existing communication on the connection identifier may be unaffected. The type of service requested may not be supported by the network to all destinations.
