RDMA/(core, ulp): Convert register/unregister event handler to be void

2017-08-24T20:27:10+00:00

The functions ib_register_event_handler() and ib_unregister_event_handler() always returned success and they can't fail. Let's convert those functions to be void, remove redundant checks and cleanup tons of goto statements. Signed-off-by: Leon Romanovsky Reviewed-by: Dennis Dalessandro Signed-off-by: Doug Ledford

IB/iser: Handle lack of memory management extentions correctly

2017-07-11T14:47:16+00:00

max_fast_reg_page_list_len is only valid when the memory management extentions are signaled by the underlying driver. Fix by adjusting iser_calc_scsi_params() to use ISCSI_ISER_MAX_SG_TABLESIZE when the extentions are not indicated.

RDMA/iser: Fix possible mr leak on device removal event

2017-03-25T02:31:19+00:00

When the rdma device is removed, we must cleanup all the rdma resources within the DEVICE_REMOVAL event handler to let the device teardown gracefully. When this happens with live I/O, some memory regions are occupied. Thus, track them too and dereg all the mr's. We are safe with mr access by iscsi_iser_cleanup_task.

IB/iser: Protect completion context active_qps update

2017-02-19T14:18:31+00:00

As iser connections can share completion contexts, we need to protect the active_qps update each time we set it. Signed-off-by: Max Gurtovoy Acked-by: Sagi Grimberg Signed-off-by: Doug Ledford

IB/core: add support to create a unsafe global rkey to ib_create_pd

2016-09-23T17:47:44+00:00

Instead of exposing ib_get_dma_mr to ULPs and letting them use it more or less unchecked, this moves the capability of creating a global rkey into the RDMA core, where it can be easily audited. It also prints a warning everytime this feature is used as well.
