Current code overestimates the value of max_outstanding_req_per_channel for Win8 and newer hosts, since vmscsi_size_delta is set to the initial value of sizeof(vmscsi_win8_extension) rather than zero. This may lead to wrong decisions when using ring_avail_percent_lowater equals to zero. The estimate of max_outstanding_req_per_channel is 'exact' for Win7 and older hosts. A better choice, keeping the algorithm for the estimation simple, is to err the other way around, i.e., to underestimate for Win7 and older but to use the exact value for Win8 and newer.

While testing recent discovery node rework, several items were seen that could be done better with respect to the new trace event logic. 1) in the following msg: kernel: lpfc 0000:44:00.0: start 35 end 35 cnt 0 If cnt is zero in the 1st message, there is no reason to display the 1st message, which is just giving start/end positioning. Fix by not displaying message if cnt is 0. 2) If the driver is loaded with module log verbosity off, and later a single NPIV host instance verbosity is enabled via sysfs, it enables messages on all instances. This is due to the trace log verbosity checks (lpfc_dmp_dbg) looking at the phba only. It should look at the phba and the vport. Fix by enabling a check on both phba and vport. 3) in the following messages: 2904 Firmware Dump Image Present on Adapter 2887 Reset Needed: Attempting Port Recovery... These messages are not necessary for the trace event log, which is primarily for discovery. Fix by changing log level on these 2 messages to LOG_SLI.

Several errors have occurred where the adapter stops or fails but does not raise the register values for the driver to detect failure. Thus driver is unaware of the failure. The failure typically results in I/O timeouts, the I/O timeout handler failing (after several seconds), and the error handler escalating recovery policy and resulting in more errors. Eventually, the driver is in a position where things have spiraled and it can't do recovery because other recovery ops are still outstanding and it becomes unusable. Resolve the situation by having the I/O timeout handler (actually a els, SCSI I/O, NVMe ls, or NVMe I/O timeout), in addition to aborting the I/O, perform a mailbox command and look for a response from the hardware. If the mailbox command fails, it will mark the adapter offline and then invoke the adapter reset handler to clean up. The new I/O timeout test will be limited to a test every 5s. If there are multiple I/O timeouts concurrently, only the 1st I/O timeout will generate the mailbox command. Further testing will only occur once a timeout occurs after a 5s delay from the last mailbox command has expired.

When lpfc is running in NVMET mode and supports the NVME-1 addendum changes, a LIP on a bound NVME Initiator or lipping the lpfc NVMET's link resulted in an Oops in lpfc_nvmet_host_release. The fix requires lpfc NVMET to maintain an additional reference on any node structure that acts as the hosthandle for the NVMET transport. This reference get is a one-time addition, is taken prior to the upcall of an unsolicited LS_REQ, and is released when the NVMET transport releases the hosthandle during the host_release downcall.

When with testing with large numbers of npiv vports and link bounces, the driver is flooding the messages file, even with log_verbose = 0.

If a mailbox command times out, the SLI port is deemed in error and the port is reset. The HBA cleanup is not returning I/Os to the NVMe layer before the port is unregistered. This is due to the HBA being marked offline (!SLI_ACTIVE) and cleanup being done by the mailbox timeout handler rather than an general adapter reset routine. The mailbox timeout handler mailbox handler only cleaned up SCSI I/Os. Fix by reworking the mailbox handler to: - After handling the mailbox error, detect the board is already in failure (may be due to another error), and leave cleanup to the other handler. - If the mailbox command timeout is initial detector of the port error, continue with the board cleanup and marking the adapter offline (!SLI_ACTIVE). Remove the SCSI-only I/O cleanup routine. The generic reset adapter routine that is subsequently invoked, will clean up the I/Os. - Have the reset adapter routine flush all NVMe and SCSI I/Os if the adapter has been marked failed (!SLI_ACTIVE). - Rework the NVMe I/O terminate routine to take a status code to fail the I/O with and update so that cleaned up I/O calls the wqe completion routine. Currently it is bypassing the wqe cleanup and calling the NVMe I/O completion directly. The wqe completion routine will take care of data structure and node cleanup then call the NVMe I/O completion handler.

Target reset is failed by the target as an invalid command. The Target Reset TMF has been obsoleted in T10 for a while, but continues to be used. On (newer) devices, the TMF is rejected causing the reset handler to escalate to adapter resets. Fix by having Target Reset TMF rejections be translated into a LOGO and re-PLOGI with the target device. This provides the same semantic action (although, if the device also supports nvme traffic, it will terminate nvme traffic as well - but it's still recoverable).

A successful task mgmt command is logging errors, making it look like problems were encountered. This is due to log messages for the device/target and bus reset handlers having the LOG_TRACE_EVENT flag set.

In the lpfc offline routine, called for various reasons such as sysfs attribute, driver unload, or port error, the driver is calling __lpfc_cpuhp_remove() to destroy the hot plug data. If the offline routine is called while the driver is in the process of being unloaded, a request using lpfc_cpuhp_remove() is also made from lpfc_sli4_hba_unset(). The cpuhp elements are no longer valid when the second removal request is made. Fix by only calling the cpuhp removal once when the adapter is in the process of unloading.

If the port is configured for NVME and has any outstanding IOs when a FW reset is requesteed, outstanding I/Os are not properly cleaned up. This causes the fw download request to fail.

When lpfc generates a GEN_REQUEST wqe for the nvme LS (such as Create Association), the timeout is set to R_A_TOV without regard to the timeout value supplied by the nvme-fc transport. The driver should be setting the timeout to the value passed into the routine. Additionally the caller should be setting the timeout value to the value in the ls request set by the nvme transport. Instead, it unconditionally is setting it to a driver defined value. So the driver actually overrode the value twice. Fix by using the timeout provided to the routine, and for the caller, set the timeout to the ls request timeout value.

The driver's management of the fabric controller (aka pseudo-scsi initiator) node in SLI3 mode is causing this crash. The crash occurs because of a node reference imbalance that frees the fabric controller node while devloss is outstanding from the SCSI transport. This is triggered by an odd behavior where the switch reacts to a rejected RDP request with a PLOGI and nothing else, not even a LOGO. The driver ACKS the PLOGI and after successfully registering the RPI, incorrectly registers the fabric controller node because it has the NLP_FC4_FCP flag still set from the fabric controller PRLI. If a LIP is issued, the driver attempts to cleanup on Link Up and ends up executing too many puts. Fix by detecting the fabric node type and clearing out the nodes internal flags that triggered a SCSI transport registration and subsequence dev_loss event. The driver cannot count on any persistence from fabric controller nodes. Link: https://lore.kernel.org/r/20210104180240.46824-5-jsmart2021@gmail.comCo-developed-by:

Testing with target ports coming and going, the driver eventually reached a state where it no longer discovered the target. When the driver has issued a PRLI and receives a PRLI from the target, it is not properly updating the node's initiator/target role flags. Thus, when a subsequent RSCN is received for a target loss, the driver mis-identifies the target as an initiator and does not initiate LUN scanning. Fix by always refreshing the ndlp with the latest PRLI state information whenever a PRLI is processed. Also clear the ndlp flags when processing a PLOGI so that there is no carry over through a re-login. Link: https://lore.kernel.org/r/20210104180240.46824-4-jsmart2021@gmail.comCo-developed-by:

A very long time ago, there was a feature: auto sli mode. It gave the user the ability to auto select the SLI mode (SLI2 or SLI3) to run the port in, or even force SLI2 mode if configured. Because of the convoluted logic, the CONFIG_PORT mbox command ends up being called 2 or 3 times. It should have been called only once. Additionally, the driver no longer supports SLI-2, so only SLI-3 mode should be allowed. The following changes were made: - Force module parameter to SLI3 only. - Rip out redundant CONFIG_PORT mbox commands. - Force CONFIG_PORT mbox command to be in beginning of enable ISR routine. - Added changes for offline to online behavior Link: https://lore.kernel.org/r/20210104180240.46824-3-jsmart2021@gmail.comCo-developed-by:

Under some pt2pt situations, the other end of the link may issue a LOGO after successfully completing PLOGI and assigning addresses to the port. Thus the driver may attempt a new PLOGI to re-create the login, but the LOGO handling cleared the address back to 0. Once this happens, the other end, which may be address 0, gets all confused and this cannot be resolved without an administrative action to bounce the link. Fix by assuming that address assignment only occurs on the 1st PLOGI after link up, and regardless of login state, the address assignment sticks. The FC standards aren't particularly clear in this situation (it only describes initial PLOGI), but there is nothing that contradicts this and behaviors on the devices tested appears to conform to the understanding. Thus, don't reset the port address to 0 as part of LOGO handling. Port addresses will only reset on link down.

The driver's queuecommand routine is still wrapped to hold the host lock for the duration of the call. This will become problematic when moving to multiple queues due to the lock contention preventing asynchronous submissions to mulitple queues. There is no real legitimate reason to hold the host lock, and previous patches have insured proper protection of moving ibmvfc_event objects between free and sent lists.

The primary and async CRQs are nearly identical outside of the format and length of each message entry in the dma mapped page that represents the queue data.

Currently, in the query completion trace print, since we use hba->lrb[tag].ucd_req_ptr and didn't differentiate UPIU between request and response, thus header and transaction-specific field in UPIU printed by query trace are identical.

Current EM macro definition, we use stringize operator '#', which turns the argument it precedes into a quoted string. Thus requires the symbol of __print_symbolic() should be the string corresponding to the name of the enum. However, we have other cases, the symbol and enum name are not the same, we can redefine EM/EMe, but there will introduce some redundant codes. This patch is to remove this restriction, let others reuse the current EM/EMe definition. Link: https://lore.kernel.org/r/20210105113446.16027-2-huobean@gmail.comAcked-by:
