When a canister on a FS9100, or similar storage, running in NPIV mode, is rebooted, its WWPNs will fail over to another canister. When this occurs, we see a WWPN going away from the fabric at one N-Port ID, and, a short time later, the same WWPN appears at a different N-Port ID. When the canister is fully operational again, the WWPNs fail back to the original canister. If there is any I/O outstanding to the target when this occurs, it will result in the implicit logout the ibmvfc driver issues before removing the rport to fail. When the WWPN then shows up at a different N-Port ID, and we issue a PLOGI to it, the VIOS will see that it still has a login for this WWPN at the old N-Port ID, which results in the VIOS simulating a link down / link up sequence to the client, in order to get the VIOS and client LPAR in sync. The patch below improves the way we handle this scenario so as to avoid the link bounce, which affects all targets under the virtual host adapter. The change is to utilize the Move Login MAD, which will work even when I/O is outstanding to the target. The change only alters the target state machine for the case where the implicit logout fails prior to deleting the rport. If this implicit logout fails, we defer deleting the ibmvfc_target object after calling fc_remote_port_delete. This enables us to later retry the implicit logout after terminate_rport_io occurs, or to issue the Move Login request if a WWPN shows up at a new N-Port ID prior to this occurring. This has been tested by IBM's storage interoperability team on a FS9100, forcing the failover to occur. With debug tracing enabled in the ibmvfc driver, we confirmed the move login was sent in this scenario and confirmed the link bounce no longer occurred.

Boot occasionally fails with some Samsung low-power UFS devices. The reason is that these devices have a little bit higher latency for NOP OUT responses. This causes boot to fail because the NOP OUT command is issued during initialization to check whether the device transport protocol is ready or not. Increase NOP_OUT_TIMEOUT value from 30 to 50ms.

The driver will throw an error message when a tampered type controller is detected. The intent is to avoid interacting with any firmware which is not secured/signed by Broadcom. Any tampering on firmware component will be detected by hardware and it will be communicated to the driver to avoid any further interaction with that component.

While reviewing commit 936e6b85 ("scsi: zfcp: Fix panic on ERP timeout for previously dismissed ERP action"), I stumbled over zfcp_fsf_req_complete() and wondered whether it has similar issues wrt concurrent modification of req->erp_action by zfcp_erp_strategy_check_fsfreq(). But a closer look shows that both its two callers [zfcp_fsf_reqid_check(), zfcp_fsf_req_dismiss_all()] remove the request from the adapter's req_list under the req_list's lock. Hence we can trust that if zfcp_erp_strategy_check_fsfreq() concurrently looks up the corresponding req_id, it won't find this request and is thus unable to modify it while it's being processed by zfcp_fsf_req_complete(). Add a code comment that hopefully makes this easier for future readers, and condense the two accesses to ->erp_action that made me trip over this code path in the first place.

It was observed on an ISP8324 16Gb HBA with fw=8.08.203 (d0d5) in a PowerPC64 machine that pkt->entry_type was MBX_IOCB_TYPE/0x39 with an sp->type SRB_SCSI_CMD which is invalid and should not be possible. Reading the entry_type from the crash dump shows the expected value of STATUS_TYPE/0x03 but the call trace shows that qla24xx_mbx_iocb_entry() is used. Add a check to verify for consistency and reset the HBA if an invalid state is reached. Obviously, this is only a workaround until the real problem is solved.
