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.

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.

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.

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.

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.

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.

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.

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().

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.

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.

Most drives from Seagate, Hitachi, and possibly other brands, do not allow LBA28 access to sector number 0x0fffffff (2^28 - 1). So instead use LBA48 for such accesses. This bug could bite a lot of systems, especially when the user has taken care to align partitions to 4KB boundaries. On misaligned systems, it is less likely to be encountered, since a 4KB read would end at 0x10000000 rather than at 0x0fffffff.

I don't claim to understand the tty layer, but it seems like hvc_open and hvc_close should be balanced in their kref reference counting. Right now we get a kref every call to hvc_open: if (hp->count++ > 0) { tty_kref_get(tty); <----- here spin_unlock_irqrestore(&hp->lock, flags); hvc_kick(); return 0; } /* else count == 0 */ tty->driver_data = hp; hp->tty = tty_kref_get(tty); <------ or here if hp->count was 0 But hvc_close has: tty_kref_get(tty); if (--hp->count == 0) { ... /* Put the ref obtained in hvc_open() */ tty_kref_put(tty); ... } tty_kref_put(tty); Since the outside kref get/put balance we only do a single kref_put when count reaches 0. The patch below changes things to call tty_kref_put once for every hvc_close call, and with that my machine boots fine.
