IB/core: Change ib_create_cq to use struct ib_cq_init_attr

2015-06-12T18:49:10+00:00

Currently, ib_create_cq uses cqe and comp_vecotr instead of the extendible ib_cq_init_attr struct. Earlier patches already changed the vendors to work with ib_cq_init_attr. This patch changes the consumers too. Signed-off-by: Matan Barak Signed-off-by: Or Gerlitz Signed-off-by: Doug Ledford

IB/iser: Align to generic logging helpers

IB/iser: Move PI context alloc/free to routines

2015-04-15T20:07:13+00:00

Make iser_[create|destroy]_fastreg_desc shorter, more readable and easily extendable. This patch does not change any functionality. Signed-off-by: Sagi Grimberg Signed-off-by: Adir Lev Signed-off-by: Doug Ledford

IB/iser: Get rid of struct iser_rdma_regd

2015-04-15T20:07:13+00:00

This struct members other than struct iser_mem_reg are unused, so remove it altogether. This patch does not change any functionality. Signed-off-by: Sagi Grimberg Signed-off-by: Adir Lev Signed-off-by: Doug Ledford

IB/iser: Move memory reg/dereg routines to iser_memory.c

2015-04-15T20:07:12+00:00

As memory registration/de-registration methods, lets move them to their natural location. While we're at it, make iser_reg_page_vec routine static. This patch does not change any functionality. Signed-off-by: Sagi Grimberg Signed-off-by: Doug Ledford

IB/iser: Handle fastreg/local_inv completion errors

2015-04-15T20:07:12+00:00

Fast registration and local invalidate work requests can also fail. We should call error completion handler for them. Reported-by: Roi Dayan Signed-off-by: Sagi Grimberg Signed-off-by: Doug Ledford

IB/iser: Fix unload during ep_poll wrong dereference

2015-04-15T20:07:12+00:00

In case the user unloaded ib_iser while ep_connect is in progress, we need to destroy the endpoint although ep_disconnect wasn't invoked (we detect this by the iser conn state != DOWN). However, if we got an REJECTED/UNREACHABLE CM event we move the connection state to DOWN which will prevent us from destroying the endpoint in the module unload stage. Fix this by setting the connection state to TERMINATING in iser_conn_error so we can still destroy the endpoint at unload stage.

IB/iser: Release the iscsi endpoint if ep_disconnect wasn't called

2015-02-17T20:33:14+00:00

In some cases, we might reach the iser connection termination without ep_disconnect being invoked (for example if user-space daemon doesn't exists. In this case, we need to free the iscsi endpoint when we remove the iser connection. Signed-off-by: Ariel Nahum Signed-off-by: Sagi Grimberg Signed-off-by: Roland Dreier

IB/iser: Fix memory regions possible leak

2015-02-17T20:32:46+00:00

When teardown process starts during live IO, we need to keep the memory regions pool (frmr/fmr) until all in-flight tasks are properly released, since each task may return a memory region to the pool. In order to do this, we pass a destroy flag to iser_free_ib_conn_res to indicate we can destroy the device and the memory regions pool. iser_conn_release will pass it as true and also DEVICE_REMOVAL event (we need to let the device to properly remove). Also, Since we conditionally call iser_free_rx_descriptors, remove the extra check on iser_conn->rx_descs.
