The device may notify the host of an extreme temperature by using the exception event mechanism. The exception can be raised when the device’s Tcase temperature is either too high or too low. It is essentially up to the platform to decide what further actions need to be taken. leave a placeholder for a designated vop for that.

Under the session level spinlock node->active_ios_lock in efct_scsi_io_alloc() we are taking another spinlock for the port. This leads to contention between sessions and even between I/Os in the same session. Reduce the locked region to active_ios list for which active_ios_lock is intended. Spinlock CPU usage decreases from 18% down to 13%. IOPS are increased from 220 kIOPS to 264 kIOPS for one LUN. Link: https://lore.kernel.org/r/20210914105539.6942-4-d.bogdanov@yadro.comReviewed-by:

As noted in the "Deprecated Interfaces, Language Features, Attributes, and Conventions" documentation [1], size calculations (especially multiplication) should not be performed in memory allocator (or similar) function arguments due to the risk of them overflowing. This could lead to values wrapping around and a smaller allocation being made than the caller was expecting. Using those allocations could lead to linear overflows of heap memory and other misbehaviors. Use the purpose specific kcalloc() function instead of the argument count * size in the kzalloc() function.

The PBDE feature, setting payload buffer address explicitly in the WQE so it doesn't have to be fetched from the SGL, only makes sense when there is a single buffer for the I/O. When there are multiple buffers it actually hurts performance as the SGL subsequently has to be fetched. Rework the SGL logic to only use PBDE when a single buffer.

Injecting errors on the PCI slot while the driver is handling NVMe I/O will cause crashes and hangs. There are several rather difficult scenarios occurring. The main issue is that the adapter can report a PCI error before or simultaneously to the PCI subsystem reporting the error. Both paths have different entry points and currently there is no interlock between them. Thus multiple teardown paths are competing and all heck breaks loose. Complicating things is the NVMs path. To a large degree, I/O was able to be shutdown for a full FC port on the SCSI stack. But on NVMe, there isn't a similar call. At best, it works on a per-controller basis, but even at the controller level, it's a controller "reset" call. All of which means I/O is still flowing on different CPUs with reset paths expecting hw access (mailbox commands) to execute properly. The following modifications are made: - A new flag is set in PCI error entrypoints so the driver can track being called by that path. - An interlock is added in the SLI hw error path and the PCI error path such that only one of the paths proceeds with the teardown logic. - RPI cleanup is patched such that RPIs are marked unregistered w/o mbx cmds in cases of hw error. - If entering the SLI port re-init calls, a case where SLI error teardown was quick and beat the PCI calls now reporting error, check whether the SLI port is still live on the PCI bus. - In the PCI reset code to bring the adapter back, recheck the IRQ settings. Different checks for SLI3 vs SLI4. - In I/O completions, that may be called as part of the cleanup or underway just before the hw error, check the state of the adapter. If in error, shortcut handling that would expect further adapter completions as the hw error won't be sending them. - In routines waiting on I/O completions, which may have been in progress prior to the hw error, detect the device is being torn down and abort from their waits and just give up. This points to a larger issue in the driver on ref-counting for data structures, as it doesn't have ref-counting on q and port structures. We'll do this fix for now as it would be a major rework to be done differently. - Fix the NVMe cleanup to simulate NVMe I/O completions if I/O is being failed back due to hw error. - In I/O buf allocation, done at the start of new I/Os, check hw state and fail if hw error.

Currently, we hold off unregistering with NVMe transport layer until GID_FT or ADISC completes upon receipt of RSCN. In the ADISC discovery routine, for nodes not found in the GID_FT response, the nodes are unregistered from the SCSI transport but not UNREG_RPI'd. Meaning outstanding WQEs continue to be outstanding and were not failed back to the OS. If an NVMe device, this mean there wasn't initial termination of the I/Os so they could be issued on a different NVMe path. Fix by unregistering the RPI so that I/O is cancelled.

In pt-2-pt mode, the initiator does not log into the target after a PRLI error. In pt-2-pt mode, the target responded to the PRLI by sending a LOGO. The LOGO causes all ELS and I/Os to be aborted. This caused the PRLI to fail. The PRLI completion path caused the discovery node to be dropped to avoid being stick in an UNUSED (not logged in) state. As the node was dropped there is no retry of the login and as it is pt-2-pt, there is no RSCN to retrigger discovery. Thus the other end is not seen by the OS. Fix by ensuring the discovery node is not dropped if connecting pt-2-pt. This will cause PLOGI to be retried.

On link up and node discovery, a remote port is registered with the SCSI transport and the driver sets fc4_xpt_flags to track transport registration. A link down event causes the driver to deregister with the SCSI transport, starting the devloss timer, and calls a local unreg routine to clear the login state. Part of the login state is the fc4_xpt_flags. However, with tape devices that support sequence level error recovery, which wants to preserve the login, the local unreg routine is skipped, thus the flags aren't cleared. A subsequent link up, ADISC is performed and the lpfc_nlp_reg_node() routine is called. As the fc4_xpt_flags is not clear, it's believed the node is already registered with the transport. Unfortunately, the registration was already terminated. Eventually the devloss tmo timer expires and tears down the device. Fix by ensuring the tape device, known by the ADISC flag, is always unregistered if the link drops. Link: https://lore.kernel.org/r/20210910233159.115896-6-jsmart2021@gmail.comCo-developed-by:

A test scenario encountered an unload hang while an FLOGI ELS was in flight when a link down condition occurred. The driver fails unload as it never releases the fport node. For most nodes, when the link drops, devloss tmo is started and the timeout will cause the final node release. For the Fport, as it has not yet registered with the SCSI transport, there is no devloss timer to be started, so there is no final release. Additionally, the link down sequence causes ABORTS to be issued for pending ELS's. The completions from the ABORTS perform the release of node references. However, as the adapter is being reset to be unloaded, those completions will never occur. Fix by the following: - In the ELS cleanup, recognize when unloading and place the ELS's on a different list that immediately cleans up/completes the ELS's. It's recognized that this condition primarily affects only the fport, with other ports having normal clean up logic that handles things. - Resolve the devloss issue by, when cleaning up nodes on after link down, recognizing when the fabric node does not have a completed state (its state is UNUSED) and removing a reference so the node can delete after the ELS reference is released.

A test scenario has a target issuing a TPLS after accepting the driver's PRLI. TPLS is not supported by the driver so it rejects the ELS. However, the reject was only happening on the primary N_Port. If the TPLS was to a NPIV vport, not only would it reject the ELS, but it would act on the TPLS, starting devloss, then unregister from the SCSI transport and release the node. When devloss expired, it would access the node again and cause a page faul. Fix by altering the NPIV code to recognize that a correctly registered node can reject unsolicited ELS I/O and to not unregister with the SCSI transport and tear the node down. Add a check of the fc4_xpt_flags so that only a zero value allows the unreg and teardown. Link: https://lore.kernel.org/r/20210910233159.115896-4-jsmart2021@gmail.comCo-developed-by:

In a rarely executed path, FLOGI failure, there is a refcounting error. If FLOGI completed with an error, typically a timeout, the initial completion handler would remove the job reference. However, the job completion isn't the actual end of the job/exchange as the timeout usually initiates an ABTS, and upon that ABTS completion, a final completion is sent. The driver removes the reference again in the final completion. Thus the imbalance. In the buggy cases, if there was a link bounce while the delayed response is outstanding, the fport node may be referenced again but there was no additional reference as it is already present. The delayed completion then occurs and removes the last reference freeing the node and causing issues in the link up processed that is using the node. Fix this scenario by removing the snippet that removed the reference in the initial FLOGI completion. The bad snippet was poorly trying to identify the FLOGI as OK to do so by realizing the node was not registered with either SCSI or NVMe transport.

When parsing the txq list in lpfc_drain_txq(), the driver attempts to pass the requests to the adapter. If such an attempt fails, a local "fail_msg" string is set and a log message output. The job is then added to a completions list for cancellation. Processing of any further jobs from the txq list continues, but since "fail_msg" remains set, jobs are added to the completions list regardless of whether a wqe was passed to the adapter. If successfully added to txcmplq, jobs are added to both lists resulting in list corruption. Fix by clearing the fail_msg string after adding a job to the completions list. This stops the subsequent jobs from being added to the completions list unless they had an appropriate failure.

Commit 1f02beff ("scsi: pm80xx: Remove global lock from outbound queue processing") introduced a lock per outbound queue. Prior to that change the driver was using a global lock for all outbound queues. While processing the I/O responses and events the driver takes the outbound queue spinlock and is supposed to release it in pm8001_ccb_task_free_done() before calling command done(). Since the older code was using a global lock, pm8001_ccb_task_free_done() was releasing the global spin lock. The change that split the lock per outbound queue did not consider this and pm8001_ccb_task_free_done() was still releasing the global lock.
