2021-08-23scsi: qla2xxx: Open-code qla2xxx_eh_device_reset()Hannes Reinecke1-31/+23
Device reset and target reset will be using different calling sequences, so open-code __qla2xxx_eh_generic_reset() in qla2xxx_eh_device_reset(), and remove the now obsolete function __qla2xxx_eh_generic_reset(). No functional changes.

2021-08-23scsi: qla2xxx: Do not call fc_block_scsi_eh() during bus resetHannes Reinecke1-10/+0
When calling bus reset the driver will be doing a full SAN resync, so there is no need to wait for any pending RSCNs; they'll be re-issued during resync anyway.

2021-08-23scsi: qla2xxx: Fix NVMe session down detectionQuinn Tran3-5/+26
When Target port transitions personality from one to another (NVMe <--> FCP), there could be some overlap of the two where one layer is going down while the other layer is coming up. This overlap can cause temporary I/O error. Detect those errors/transitions and recover from them. Triggers session tear down and allow relogin to re-drive the connection under the following conditions: - NVMe command error - On PRLO + N2N (rida format 2) Link: https://lore.kernel.org/r/20210817051315.2477-11-njavali@marvell.com Signed-off-by: Quinn Tran <qutran@marvell.com> Signed-off-by: Nilesh Javali <njavali@marvell.com> Signed-off-by: Martin K.

2021-08-23scsi: qla2xxx: Fix NVMe retryQuinn Tran5-26/+40
For target port that register itself as both FCP + NVMe, initiator driver will try to login one mode at a time. If the last mode did not succeed, then driver will try the other mode. When error is encountered, current code only flip to other mode one time (NVMe->FCP) and remain on the last mode. Driver wrongly assumed target port does not support PRLI NVMe, instead it was not ready to receive PRLI. This patch will alternate back and forth on every PRLI failure until login retry count has depleted or it is succeeded.

The abort callback gets called only when it gets posted to firmware. The refcounting is done properly in the callback. On internal errors, the callback is not invoked leading to a hung I/O.

Abort threads were getting out without processing due to the "deleted" flag check. The delete thread, meanwhile, could not proceed with a logout (that would have cleared out pending requests) as the logout IOCB work was not progressing. It appears like the hung qlt_free_session_done() thread is causing the ha->wq works on hold. The qlt_free_session_done() was hung waiting for nvme_fc_unregister_remoteport() + localport_delete cb to be complete, which would only happen when all I/Os are released. Fix this by allowing abort to progress until device delete is completely done. This should make the qlt_free_session_done() proceed without hang and thus clear up the deadlock.

2021-08-11scsi: qla2xxx: Sync queue idx with queue_pair_map idxSaurav Kashyap1-2/+3
The first invocation of function find_first_zero_bit will return 0 and queue_id gets set to 0. An index of queue_pair_map also gets set to 0. qpair_id = find_first_zero_bit(ha->qpair_qid_map, ha->max_qpairs); set_bit(qpair_id, ha->qpair_qid_map); ha->queue_pair_map[qpair_id] = qpair; In the alloc_queue callback driver checks the map, if queue is already allocated: ha->queue_pair_map[qidx] This works fine as long as max_qpairs is greater than nvme_max_hw_queues(8) since the size of the queue_pair_map is equal to max_qpair. In case nr_cpus is less than 8, max_qpairs is less than 8. This creates wrong value returned as qpair.

Some FC adapters from Marvell offer the ability to encrypt data in flight (EDIF). This feature requires an application to act as an authenticator. During runtime, driver and authentication application need to stay in sync in terms of: Session being down|up, arrival of new authentication message (AUTH ELS) and SADB update completion. These events are queued up as doorbell to the authentication application. Application would read this doorbell on regular basis to stay up to date. Each SCSI host would have a separate doorbell queue. The doorbell interface can daisy chain a list of events for each read. Each event contains an event code + hint to help application steer the next course of action.

Some FC adapters from Marvell offer the ability to encrypt data in flight (EDIF). This feature requires an application to act as an authenticator. There is no FC switch scan service that can indicate whether a device is secure or non-secure. In order to detect whether the remote port supports encrypted operation, driver must first do a PLOGI with the remote device. On completion of the PLOGI, driver will query firmware to see if the device supports secure login. To do that, driver + firmware must advertise the security bit via PLOGI's service parameter. The remote device shall respond using the same service parameter whether it supports it or not.

Some FC adapters from Marvell offer the ability to encrypt data in flight (EDIF). This feature requires an application to act as an authenticator. On completion of the authentication process, the authentication application will notify driver on whether it is successful or not.

In case of failure, application will use the QL_VND_SC_AUTH_FAIL bsg call to tell driver to tear down the connection and retry. In the case where an existing session is active, the re-key process can fail. The session tear down ensures data is not further compromised.

Some FC adapters from Marvell offer the ability to encrypt data in flight (EDIF). This feature requires an application to act as an authenticator. As part of the authentication process, the authentication application will generate a SADB entry (Security Association/SA, key, SPI value, etc). This SADB is then passed to driver to be programmed into hardware. There will be a pair of SADB's (Tx and Rx) for each connection. After some period, the application can choose to change the key. At that time, a new set of SADB pair is given to driver. The old set of SADB will be deleted. Add a new bsg call (QL_VND_SC_SA_UPDATE) to allow application to allow adding or deleting SADB entries. Driver will not keep the key in memory. It will pass it to HW. It is assumed that application will assign a unique SPI value to this SADB (SA + key). Driver + hardware will assign a handle to track this unique SPI/SADB.
