bug fix in the handling of the internal device reset event The reason code check in scsih_sas_device_status_change_event never evaluates as true for internal device reset, hence driver never quiesce s IO when firmware is sending a device reset. The fix is to change the evaluate to: if (event_data->ReasonCode != MPI2_EVENT_SAS_DEV_STAT_RC_INTERNAL_DEVICE_RESET && event_data->ReasonCode != MPI2_EVENT_SAS_DEV_STAT_RC_CMP_INTERNAL_DEV_RESET) return; Signed-off-by:Kashyap Desai <kashyap.desai@lsi.com> Signed-off-by:

incorrect timestamp on 32 bit platforms: The upper 32 bit of the timestamp was getting truncated when converting seconds to milliseconds, which was due to the variable being long. To fix the problem, the variable needs to be u64. Also the microseconds conversion to milliseconds was incorrect; it should be divide by 1000 instead of divide by 8. Signed-off-by:

This patch fixes some issues of mptctl_exit(). 1) It doesn't call mpt_deregister() for mptctl_taskmgmt_id => Insmoding/rmmoding mptctl.ko repeadtedly (up to MPT_MAX_PROTOCOL_DRIVERS-1 at most) can eat up all cb_idx, and that would cause a lack of MptCallbacks[], MptDriverClass[], and MptEvHandlers[]. 2) It doesn't call mpt_event_deregister() for mptctl_id => Need to call it. 3) It calls mpt_reset_deregister() for mptctl_taskmgmt_id => This could accidentally deregister an innocent reset handler that you don't want to. This patch also adds a check for mptctl_taskmgmt_id. Signed-off-by:Kei Tokunaga <tokunaga.keiich@jp.fujitsu.com> Acked-by:

When the kernel is configured for preemption, using smp_processor_id() when preemption is enabled causes a warning backtrace and is wrong since we could move off of that CPU as soon as we get the ID, and we would be referencing the wrong CPU, and possibly an invalid one if it could be hotswapped out. Remove the fc_lport_get_stats() function and explicitly use per_cpu_ptr() to get the statistics. Where preemption has been disabled by holding a _bh lock continue to use smp_processor_id(), but otherwise use get_cpu()/put_cpu(). In fcoe_recv_frame() also changed the cases where we return in the middle to do a goto to the code which bumps ErrorFrames and does a put_cpu(). Two of these cases didn't bump ErrorFrames before, but doing so is harmless because they "can't happen", due to prior length checks. Also rearranged code in fcoe_recv_frame() to have only one call to fc_exch_recv(). It's just as efficient and saves a call to put_cpu(). In fc_fcp.c, adjusted a FIXME comment for code which doesn't need fixing. Signed-off-by:

DID_ERROR cases can be ambigouos. Debugging FCP error cases will be much easier if we have debug statements when we hit these error conditions. This patch simply adds debug messages using the FC_FCP_DBG macro when we return DID_ERROR to SCSI. This way if a DID_ERROR is reproducible turning on debug_logging will give a clue to developers as to what the problem might be. Signed-off-by:

Currently fc_fcp_recv_data calls fc_fcp_retry_cmd to retry failed IO but in this case tgt is still sending data frames, therefore exchange needs to be aborted first before initiating retry. So this patch fixes this by aborting exchange first then have retry. Renames fc_timeout_error to fc_fcp_recovery since fc_timeout_error is already called from several other places beside from fcp timeout handler and then used fc_fcp_recovery for abort & retry from fc_fcp_recv_data, this rename also required renaming FC_CMD_TIME_OUT status to FC_CMD_RECOVERY to be consistent with new fc_fcp_recovery. Data frames are not expected for an DDPed exchange and potentially it could be tampered data frame, so does recovery in this case by calling fc_fcp_recovery. Signed-off-by:

Since use of offloads is more efficient than switching to non-offload EM. However kept logic same to call em_match if it is provided in the list of EMs. Converted fc_exch_alloc to inline being now tiny a function and already not an exported libfc API any more. Signed-off-by:

In some cases seq is incremented twice causing unnecessary seq jump, for instance fc_exch_recv_seq_resp increments seq id when fc_sof_is_init is true and that is true for each incoming xfer ready but then fc_fcp_send_data does another seq increment to send data for xfer ready. This patch removes all such seq id jumps, at least it eliminates few calls to fc_seq_start_next using ex_lock. Also removes seq id update with incoming frame's seq id as this is not needed since each end (I or T) just need to send incremented their own seq id on each TSI from other end & before sending new sequence within a exchange.

When starting a new response sequence in a multi-sequence exchange, a warning was issued that sequence initiative wasn't held. The bug was that sequence initiative was cleared by the previous sequence due to the END_SEQ flag being on. The intent may have been to check LAST_SEQ. Change just to check SEQ_INIT. Signed-off-by:

The link and last_link fields in the fcoe_ctlr struct are no longer useful, since they are always set to the same value, and FIP always calls libfc to pass link information to the lport. Eliminate those fields and rename link_work to timer_work, since it no longer has any link change work to do. Thanks to Brian Uchino for discovering this issue. Signed-off-by:

The method we've been using for point-to-point mode requires that the LS_ACC for the FLOGI uses the D_ID and S_ID assigned to the remote port and local port, not those in the exchange. This is not the correct method, but for now, it's what works with the old target, as well as with new targets based on libfc. This patch changes the addresses used accordingly. Signed-off-by:

When receiving a FLOGI request from a point-to-point peer, the D_ID of 0xfffffe was not recognized as belonging to one of the lports, so it was dropped. Change fc_vport_id_lookup() to treat d_id 0xfffffe as a match. Signed-off-by:

In point-to-point mode, we need to save the source MAC from received FLOGI requests to use as the destination MAC for all outgoing frames. We stopped doing that at some point. Use the lport_set_port_id method to catch incoming FLOGI frames and pass them to fcoe_ctlr_recv_flogi() so it can save the source MAC. Signed-off-by:

In point-to-point mode, the destination MAC address for the FLOGI response was zero because the LS_ACC for the FLOGI wasn't getting intercepted by FIP. Change to call fcoe_ctlr_els_send when sending any ELS, not just requests. Signed-off-by:

In point-to-point mode, if the PLOGI to the remote port times out, it can get deleted by the remote port module. Since there's no reference by the local port, lport->ptp_data points to a freed rport, and when the local port is reset and tries to logout again, an oops occurs in mutex_lock_nested(). Hold a reference count on the point-to-point rdata. Signed-off-by:

external host not connecting after controller reboot: The problem is : devices are not coming back after having the cable disconnected then reconnected. The problem is because the driver/firmware device removal handshake is failing. Due to this failure, the controller firmware is not sending out device add events when the target is reconnected. This is root caused to a race in the driver/firmware device removal algorithm. There is duplicate code in both interrupt and user context; where target reset is being issue from user context path while sas_iounit_control(OP_REMOVE) is being sent from interrupt context. An active target_reset will fail the OP_REMOVE. To fix this problem, the duplicate code has been removed from user context path. Signed-off-by:

modified _scsih_sas_device_find_by_handle so to handle the search on both list(device list and device_init_list) Also, we moved the priority of the search so the ioc->sas_device_list is done first. The "sas_device_init_list" is only used during the 1st port enable, so its unlikely there’s devices on it. Signed-off-by:

Add the cancel_pending_work flag from the fw_event_work structure, and then to set the flag during host reset, check the flag later from work threads context and if cancel_pending_work_flag is set ingore those events. Now Rescan after host reset is changed. Added special task MPT2SAS_RESCAN_AFTER_HOST_RESET. This task will be queued at the time of HBA reset. this task is treated as barrier. All work after MPT2SAS_RESCAN_AFTER_HOST_RESET will be treated as new work and will be server by callback handle. If host_recovery is going on while running RESCAN task, it will wait for shos_recovery_done completion which will be called from HBA reset DONE context. Signed-off-by:

The rport structure defines dev_loss_tmo as u32, which is later multiplied with HZ to get the actual timeout value. This might overflow for large dev_loss_tmo values. So we should be better using u64 as intermediate variables here to protect against overflow. Signed-off-by:
