Various oops being seen on being in the ISR too long and cpu lockups, when under heavy load. The amount of work being posted off of completion queues kept the ISR running almost all the time Correct the issue by limiting the amount of work per iteration. [mkp: typo] Signed-off-by:

When using fabric-assigned WWNs, the switch doesn't like copy of the FLOGI payload, which includes valid VVL bits, to be used as the FDISC payload. Rather than wait for corrected switch firmware, ensure the VVL bits are marked invalid on FDISCs. [mkp: typo] Signed-off-by:

A race condition was found whereby the initiator would receive the RSCN for a new NVME device before it had a chance to register its FC4 support with the fabric. Thus, when queried by the initiator, it would see that the target supported FC-NVME. Corrected by making the assumption that the target always supports FC-NVME thus a PRLI is sent. It's ok for the target to reject it. Signed-off-by:

In adapter reset tests, an oops was seen with a NULL pointer in lpfc_free_rq_buffer+0x20/0x60 The driver is failing to properly repost the nvmet sgl list when recovering from the reset. Thus the driver eventually trys to walk an errant buffer list. Corrected the sgl buffer recovery as well as strengthening the initialization of the bufferlist. Signed-off-by:

After lip, the driver sometimes would have two rports for the same device, allowing the namespaces to be duplicated by nvme. In lpfc_plogi_confirm_nport() the driver was not swapping the nrport maintained by the ndlp's undergoing address swapping. This allowed the 2nd rport to sneak in as it was considered a separate device. This patch adds the fixes to Swap the nrport in each ndlp and take care of the reference counts on the ndlps similar to FCP rports. Signed-off-by:

After link bounce in a NVME Pt2Pt config, the driver managed to map the same nport twice, resulting in multiple device nodes for the same namespace. In Pt2Pt, the driver must send PRLI's for both (scsi) FCP and NVME rather than using fabric aids. The driver was inconsistent on handling various PRLI completions, especially rejects, which had reject codes cross the different protocol PRLI completions. Fixed to perform the following: if nvmet mode (fc port can only be a nvme target) - rejects all unsolicitly FCP PRLI's. Never issues a FCP PRLI. The multiple protocol PRLI's are sent simultaneously. However, driver will now only state transition after both PRLI's are complete. New flags were added to aid tracking the responses from the different PRLI's. Signed-off-by:

Modify driver return error codes to align with host nvme transport. Driver isn't returning Exxx error codes to properly reflect out of resource or connectivity conditions (-EBUSY), yet there were hard error conditions returning -EBUSY. Ensure the following situations return the proper return code: - Temporary failures or temporary resource availability: -EBUSY - Connectivity issues: -ENODEV All others are treated as hard errors and return an -Exxx value that indicates the type of error. Also, lpfc_sli4_issue_wqe() was modified to not translate error from -Exxx to WQE state. This allows lpfc_nvme_fcp_io_submit() routine to just return whatever -E value was returned from other routines. Signed-off-by:

lpfc oops when it discovers a NVME target but is configured for SCSI only operation. Oops is in lpfc_nvme_register_port+0x33/0x300. The localport is not valid so it should not have been referenced. Added validity check for localport Signed-off-by:

When the switch blade is pulled out then plugged back in, the driver does not issue a PLOGI to the target When the switch blade is pulled out, it does not reset the link. The driver ends up issuing a LOGO to the target, and finally sees devloss. Since the driver believes that a LOGO is outstanding, it does not issue a PLOGI to the target upon link up Correct by placing the ndlp in UNUSED state When devloss happens in LOGO_ISSUE state.

The driver does not discover targets when in loop mode. The NLP type is correctly getting set when a fabric connection is detected but, not for loop. The unknown NLP type means that the driver does not issue a PRLI when in loop topology. Thus target discovery fails. Fix by checking the topology during discovery. If it is loop, set the NLP FC4 type to FCP. Signed-off-by:

Message "0271 Illegal State Transition: node" seen in logs, all luns are unuseable for that target. A window exists in the rcv_plogi path where if the state is plogi issue but the driver has not issued a plogi, then two reglogins will be sent for the same RPI. The first one to complete will advance the state to prli issue the second one will be detected as an illegal state, and leave the node in an unusable state. Correct the completion routine for the PLOGI ACC that detects the state change when the driver starts discovery on the node again and drop the REGLOGIN mailbox command. Signed-off-by:

If there are IO's running and host reset or chip reset is triggered, IO's can fail due to rport time out. During chip reset recovery process, driver notifies the transport layer that remote port no longer exist, by calling fc_remote_port_delete(). When this function is called, it actually delays deletion by "blocking" it. It sets the remote port state to "FC_PORTSTATE_BLOCKED" and sets FC_RPORT_DEVLOSS_PENDING. When driver tries to abort the command by calling its abort handler function, abort handler will wait until remote port state is blocked state or wait for dev_loss_tmo time. Due to this blocking, rport times out and results in an IO failure. This patch adds a check for any active reset process before calling abort handler function. [mkp: typo] Signed-off-by:

SFP can come in 2 formats: short range/SR and long range/LR. For LR, user the can increase the number of Buffer to Buffer credits between end points via Cavium's command line tool. By default, FW uses a lower BB Credit value optimized for SR. This patch will read the SFP for each link up event and during chip reset sequence. If the SFP type and setting are mismatch, then the chip is reset 1 time to use the appropriate setting. Signed-off-by:
