2017-08-25scsi: Suppress gcc 7 fall-through warnings reported with W=1Bart Van Assche2-2/+10
The conclusion of a recent discussion about the new warnings reported by gcc 7 is that the new warnings reported when building with W=1 should be suppressed. However, gcc 7 still warns about fall-through in switch statements when building with W=1. Suppress these warnings by annotating the SCSI core properly. See also Linus Torvalds, Lots of new warnings with gcc-7.1.1, 11 July 2017 (https://www.mail-archive.com/linux-media@vger.kernel.org/msg115428.html).

2017-08-24scsi: lpfc: Fix bad sgl reposting after 2nd adapter resetDick Kennedy1-2/+9
Port issue was fixed, the hbacmd reset would take more than 8 minutes to complete. There were conflicting NVME SGL posting/reposting responsibilities between lpfc_online()/lpfc_sli4_hba_setup() and lpfc_nvme_create_localport(). The lpfc_online() causes a REPOST on existing NVME SGLs which is not released during the fc port reset. However, lpfc_nvme_create_localport() wants to allocate new NVME buffers and post them. Both cancelled out each other which had a side effect of hosing the mailbox handling that was used to remove the sgl lists - causing multiple 60s mbx timeouts. Fix by preserving all SGL lists over the fc port reset.

2017-08-24scsi: lpfc: Fix MRQ > 1 context list handlingDick Kennedy8-97/+234
Various oops including cpu LOCKUPs were seen. For asynchronously received ius where the driver must assign exchange resources, the resources were on a single get (free) list and put list (finished, waiting to be put on get list). As all cpus are sharing the lists, an interrupt for a receive frame may have to wait for all the other cpus to place their done work onto the put list before it can acquire the lock to pull from the list. Fix by breaking the resource lists into per-cpu lists or at least more than 1 list with cpu's sharing the lists). A cpu would allocate from the free list for its own cpu, and put its done work on the its own put list - avoiding the contention. As cpu load may vary, when empty, a cpu may grab from another cpu, thereby changing resource distribution. But searching for a resource only occurs on 1 or a few cpus until a single resource can be allocated. if the condition reoccurs, it starts looking at a different cpu.

2017-08-24scsi: lpfc: Fix duplicate NVME rport entries and namespaces.Dick Kennedy1-0/+20
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.

2017-08-24scsi: lpfc: Fix handling of FCP and NVME FC4 types in Pt2Pt topologyDick Kennedy3-0/+38
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.

2017-08-24scsi: qla2xxx: Do not call abort handler function during chip resetSawan Chandak1-0/+2
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.

2017-08-24scsi: qla2xxx: Handle PCIe error for driverSawan Chandak1-4/+28
Driver will perform following - Set PFLG_DRIVER_REMOVING flag and do not disable PCIe error reporting during adapter shutdown. - If PCIe device count is already zero, return correct error type from PCI error interface. - When device is offline, return correct error type from PCIe error path. - If there is board disable thread active during shutdown and PCIe device count is zero then cancel scheduling board disable thread during shutdown and return.
