When unattaching, the driver did not unmap the DPP bar. This caused the next load of the driver, which attempts to enable wc, to not work correctly and wc to be disabled due to an address mapping overlap. Fix by unmapping on unattach.

The order of the flags/checks for adapters where FC-AL is supported erroneously excluded lpe35000 adapter models. Also noted that the G7 flags for Loop and Persistent topology are incorrect. They should follow the rules as G6. Rework the logic to enable LPe35000 FC-AL support. Collapse G7 support logic to the same rules as G6.

/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:

This patch fixes offset for Format-2 data structure for Report ID Acquisition. This caused driver to set remote_nport_id to 0x0000 in N2N configuration. In a scenario where initiator's WWPN is higher than target's WWPN, driver will assign 0x00 as target nport-id, which results into login failure.

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.

During suspend flow, interrupt shall be disabled before disabling clocks to avoid potential system hang due to accessing host registers after host clocks are disabled. For example, if an interrupt comes with IRQF_IRQPOLL flag configured with the misrouted interrupt recovery feature enabled, ufshcd ISR may be triggered even if nothing shall be done for UFS. In this case, system hang may happen if UFS interrupt status register is accessed with host clocks disabled.

During power mode change, PACP_PWR_Req frame sends PAPowerModeUserData parameters (and they are considered valid by device if Flags[4] - UserDataValid bit is set in the same frame). Currently we don't set these PAPowerModeUserData parameters and hardware always sets UserDataValid bit which would clear all the DL layer timeout values of the peer device after the power mode change. This change sets the PAPowerModeUserData[0..5] to UniPro specification recommended default values, in addition we are also setting the relevant DME_LOCAL_* timer attributes as required by UFS HCI specification.
