IB/srpt: Fix abort handling

2018-04-13T17:52:09Z

[ Upstream commit 55d694275f41a1c0eef4ef49044ff29bc3999490 ] Let the target core check the CMD_T_ABORTED flag instead of the SRP target driver. Hence remove the transport_check_aborted_status() call. Since state == SRPT_STATE_CMD_RSP_SENT is something that really should not happen, do not try to recover if srpt_queue_response() is called for an I/O context that is in that state. This patch is a bug fix because the srpt_abort_cmd() call is misplaced - if that function is called from srpt_queue_response() it should either be called before the command state is changed or after the response has been sent.

IB/srpt: Disable RDMA access by the initiator

2018-01-17T08:29:28Z

commit bec40c26041de61162f7be9d2ce548c756ce0f65 upstream. With the SRP protocol all RDMA operations are initiated by the target. Since no RDMA operations are initiated by the initiator, do not grant the initiator permission to submit RDMA reads or writes to the target.

IB/srpt: Simplify srpt_handle_tsk_mgmt()

[ Upstream commit 51093254bf879bc9ce96590400a87897c7498463 ] Let the target core check task existence instead of the SRP target driver. Additionally, let the target core check the validity of the task management request instead of the ib_srpt driver.

srp-target: Retry when QP creation fails with ENOMEM

2014-10-28T20:55:08Z

It is not guaranteed to that srp_sq_size is supported by the HCA. So if we failed to create the QP with ENOMEM, try with a smaller srp_sq_size. Keep it up until we hit MIN_SRPT_SQ_SIZE, then fail the connection. Reported-by: Mark Lehrer Signed-off-by: Bart Van Assche Signed-off-by: Sagi Grimberg Cc: # 3.4+ Signed-off-by: Nicholas Bellinger

ib_srpt: replace strnicmp with strncasecmp

2014-10-14T00:18:25Z

The kernel used to contain two functions for length-delimited, case-insensitive string comparison, strnicmp with correct semantics and a slightly buggy strncasecmp. The latter is the POSIX name, so strnicmp was renamed to strncasecmp, and strnicmp made into a wrapper for the new strncasecmp to avoid breaking existing users. To allow the compat wrapper strnicmp to be removed at some point in the future, and to avoid the extra indirection cost, do s/strnicmp/strncasecmp/g.
