The UFS SCSI timeout handler was needed to compensate that ufshcd_queuecommand() could return SCSI_MLQUEUE_HOST_BUSY for a long time. Commit a276c19e3e98 ("scsi: ufs: Avoid busy-waiting by eliminating tag conflicts") fixed this so the timeout handler is no longer necessary. See also commit f550c65b ("scsi: ufs: implement scsi host timeout handler").

Currently we use a mixture of %016llx, %llx, and %16llx when printing a SAS address. Since the most significant nibble of the SAS address is always 5 - as per standard - this formatting is not so important; but some fake SAS addresses for SATA devices may not be. And we have mangled/invalid address to consider also. And it's better to be consistent in the code, so use a fixed format. The SAS address is a fixed size at 64b, so we want to 0 byte extend to 16 nibbles, so use %016llx globally. Also make some prints to be explicitly hex, and tidy some whitespace issue.

When running Cisco-MDS diagnostics which perform driver-level frame loop back, the switch is reporting errors. Diagnostic has a limit on latency that is not being met by the driver. The requirement of Latency frames is that they should be responded back by the host with a maximum delay of few hundreds of microseconds. If the switch doesn't get response frames within this time frame, it fails the test. Test is failing as the lpfc-wq workqueue was overwhelmed by the packet rate and in some cases, the work element yielded to other kernel elements. To resolve, reduce the outstanding load allowed by the adapter. This ensures the driver spends a reasonable amount of time doing loopback and can do so such that latency values can be met. Load is managed by reducing the number of receive buffers posted such that the link can be backpressured to reduce load.

/sys/kernel/debug/lpfc/fn0/ras_log always shows the same ras_log even if there are link bounce events triggered via issue_lip Dynamic FW logging had logic that prematurely breaks from the buffer filling loop. Fix the check for buffer overrun by looking before copying and restricting copy length to the remaining buffer. When copying, ensure space for NULL character is left in the buffer. While in the routine - ensure the buffer is cleared before adding elements. Link: https://lore.kernel.org/r/20191218235808.31922-6-jsmart2021@gmail.comSigned-off-by:

There are reports of multiple ports on the same system displaying different hostnames in fabric FDMI displays. Currently, the driver registers the hostname at initialization and obtains the hostname via init_utsname()->nodename queried at the time the FC link comes up. Unfortunately, if the machine hostname is updated after initialization, such as via DHCP or admin command, the value registered initially will be incorrect. Fix by having the driver save the hostname that was registered with FDMI. The driver then runs a heartbeat action that will check the hostname. If the name changes, reregister the FMDI data. The hostname is used in RSNN_NN, FDMI RPA and FDMI RHBA. Link: https://lore.kernel.org/r/20191218235808.31922-5-jsmart2021@gmail.comSigned-off-by:

When the WriteObject mailbox response has change_status set to is 0x2 (Firmware Reset) or 0x04 (Port Migration Reset), the CSF field should also be checked to see if a fw reset is sufficient to enable all new features in the updated firmware image. If not, a fw reset would start the new firmware, but with a feature level equal to existing firmware. To enable the new features, a chip reset/pci slot reset would be required. Check the CSF bit when change_status is 0x2 or 0x4 to know whether to perform a pci bus reset or fw reset. Link: https://lore.kernel.org/r/20191218235808.31922-4-jsmart2021@gmail.comSigned-off-by:

This patch reworks the fdmi symbolic node name data for the following two issues: - Correcting extraneous periods following the DV and HN fdmi data fields. - Avoiding buffer overflow issues when formatting the data. The fix to the fist issue is to just remove the characters. The fix to the second issue has all data being staged in temporary storage before being moved to the real buffer.

NVMe device re-discovery does not complete. Dev_loss_tmo messages seen on initiator after recovery from a link disturbance. The failing case is the following: When the driver (as a NVME target) receives a PLOGI, the driver initiates an "unreg rpi" mailbox command. While the mailbox command is in progress, the driver requests that an ACC be sent to the initiator. The target's ACC is received by the initiator and the initiator then transmits a PLOGI. The driver receives the PLOGI prior to receiving the completion for the PLOGI response WQE that sent the ACC. (Different delivery sources from the hw so the race is very possible). Given the PLOGI is prior to the ACC completion (signifying PLOGI exchange complete), the driver LS_RJT's the PRLI. The "unreg rpi" mailbox then completes. Since PRLI has been received, the driver transmits a PLOGI to restart discovery, which the initiator then ACC's. If the driver processes the (re)PLOGI ACC prior to the completing the handling for the earlier ACC it sent the intiators original PLOGI, there is no state change for completion of the (re)PLOGI. The ndlp remains in "PLOGI Sent" and the initiator continues sending PRLI's which are rejected by the target until timeout or retry is reached. Fix by: When in target mode, defer sending an ACC for the received PLOGI until unreg RPI completes. Link: https://lore.kernel.org/r/20191218235808.31922-2-jsmart2021@gmail.comSigned-off-by:

During cable pull test case, if the port is disconnected for time larger than devloss timeout, driver does not mark path offline. In such case, instead of notifying SCSI-ML of loop down, driver goes into endless loop of device relogin because defer flag is set. With newer handling of device relogin in driver discovery, defer flag is now redundant. This patch removes defer flag and cleans up code handling port lost indication to SCSI-ML.
