2022-06-10scsi: qla2xxx: edif: Fix session thrashQuinn Tran3-2/+14
Current code prematurely sends out PRLI before authentication application has given the OK to do so. This causes PRLI failure and session teardown. Prevents PRLI from going out before authentication app gives the OK.

2022-06-10scsi: qla2xxx: edif: Fix no login after app startQuinn Tran1-0/+1
The scenario is this: User loaded driver but has not started authentication app. All sessions to secure device will exhaust all login attempts, fail, and in stay in deleted state. Then some time later the app is started. The driver will replenish the login retry count, trigger delete to prepare for secure login. After deletion, relogin is triggered. For the session that is already deleted, the delete trigger is a no-op. If none of the sessions trigger a relogin, no progress is made. Add a relogin trigger.

After initiator has burned up all login retries, target authentication application begins to run. This triggers a link bounce on target side. Initiator will attempt another login.

2022-03-15scsi: qla2xxx: Fix laggy FC remote port session recoveryQuinn Tran2-3/+18
For session recovery, driver relies on the dpc thread to initiate certain operations. The dpc thread runs exclusively without the Mailbox interface being occupied. A recent code change for heartbeat check via mailbox cmd 0 is preventing the dpc thread from carrying out its operation. This patch allows the higher priority error recovery to run first before running the lower priority heartbeat check.

2022-03-15scsi: qla2xxx: Fix hang due to session stuckQuinn Tran2-2/+21
User experienced device lost. The log shows Get port data base command was queued up, failed, and requeued again. Every time it is requeued, it set the FCF_ASYNC_ACTIVE. This prevents any recovery code from occurring because driver thinks a recovery is in progress for this session. In essence, this session is hung. The reason it gets into this place is the session deletion got in front of this call due to link perturbation. Break the requeue cycle and exit. The session deletion code will trigger a session relogin.

User experienced some of the LUN failed to get rediscovered after long cable pull test. The issue is triggered by a race condition between driver setting session online state vs starting the LUN scan process at the same time. Current code set the online state after notifying the session is available. In this case, trigger to start the LUN scan process happened before driver could set the session in online state. LUN scan ends up with failure due to the session online check was failing. Set the online state before reporting of the availability of the session.

2022-02-17treewide: Replace zero-length arrays with flexible-array membersGustavo A. R. Silva4-6/+6
There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. Kernel code should always use “flexible array members”[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2]. This code was transformed with the help of Coccinelle: (next-20220214$ spatch --jobs $(getconf _NPROCESSORS_ONLN) --sp-file script.cocci --include-headers --dir . > output.patch) @@ identifier S, member, array; type T1, T2; @@ struct S { ... T1 member; T2 array[ - 0 ]; }; UAPI and wireless changes were intentionally excluded from this patch and will be sent out separately.
