2019-03-19scsi: lpfc: Reduce memory footprint for lpfc_queueJames Smart
Currently the driver maintains a sideband structure which has a pointer for each queue element. However, at 8 bytes per pointer, and up to 4k elements per queue, and 100s of queues, this can take up a lot of memory. Convert the driver to using an access routine that calculates the element address based on its index rather than using the pointer table.

2019-03-19scsi: lpfc: Add loopback testing to trunking modeJames Smart
When in trunking mode, the adapter can be placed into diagnostic mode and each link in the trunk tested via loopback.

2019-03-19scsi: lpfc: Fix handling of trunk links state reportingJames Smart
If all the trunk links drop and a single link resumes, the link_state is not properly reported. When trunked, the driver receives two async cqes. One acqe reports the trunk link states, which the driver records. The other cqe reports the overall state of the trunk. In the failing case, the trunk link state acqe preceeds the overall trunk link state acqe. The trunk link state acqe, as it's an "up" transition, calls a code path which ensures a down transition before moving to the up state. The down transition had a side effect of clearing the just-saved trunk link states. Fix by not clearing the trunk link states if we've already transitioned to a down state.

2019-03-19scsi: lpfc: Fix protocol support on G6 and G7 adaptersJames Smart
Invalid test is allowing Loop to be a supported topology on G6 and G7 adapters. The chips do not support loop as their link speeds prohibit loop per standard. Correct the conditional so that loop is not reported. Signed-off-by: Dick Kennedy <dick.kennedy@broadcom.com> Signed-off-by: James Smart <jsmart2021@gmail.com> Signed-off-by: Martin K.

2019-03-19scsi: lpfc: Fix io lost on host resetsJames Smart
If the driver undergoes repeated host resets it starts losing exchange structures and eventually returns SCSI_MLQUEUE_HOST_BUSY and does not recover. The offline path is not reclaiming the outstanding ios on the fcp pring txcmplq before calling lpfc_destroy_multixripool, which causes the txmcplq to be reinit and the resources lost. Flush the fcp rings before destroying the multixripools. Signed-off-by: Dick Kennedy <dick.kennedy@broadcom.com> Signed-off-by: James Smart <jsmart2021@gmail.com> Signed-off-by: Martin K.

2019-03-19scsi: lpfc: Fix mailbox hang on adapter initJames Smart
The adapter initialization sequence enables interrupts, initializes the adapter link_state to LINK_DOWN, then issues commands to initialize the adapter. The interrupt handler on the adapter validates the link_state (has to be at least LINK_DOWN) and if invalid, will discard the interrupting event. In most cases, there is not a command completion, thus an interrupt until the initialization commands have been sent which is post the setting of state to LINK_DOWN. However, in cases of firmware reset, the reset will modify the link_state to an invalid value (indicating a reset of the adapter) and there occasionally are cases where the adapter will generate an asynchronous event which shares the eq/cq used for mailbox commands. In the failure case, an interrupt is generated immediately after enabling them due to the async event. As link_state is invalid, the eq is list and the CQ not serviced. At this point link_state is initialized and the mailbox command sent. As the CQ has not been serviced, it is not armed, so no interrupt event is generated when the mailbox command completes. Modify the initialization sequence so that interrupts are enabled after link_state is properly initialized, which avoids the race condition with the async event.

2019-03-19scsi: lpfc: Fix driver crash in target reset handlerJames Smart
It's possible for the scsi error handler to fire and call the target reset handler simultaneously to the driver logging out and relogging into the system. If hit just right, the re-login may not have fully re-established the remote port and the rdata->pnod structure may be null. Check for NULL in the reset handler and return failure if NULL.
