2019-12-20scsi: qla2xxx: Remove defer flag to indicate immeadiate port lossHimanshu Madhani1-9/+9
During cable pull test case, if the port is disconnected for time larger than devloss timeout, driver does not mark path offline. In such case, instead of notifying SCSI-ML of loop down, driver goes into endless loop of device relogin because defer flag is set. With newer handling of device relogin in driver discovery, defer flag is now redundant. This patch removes defer flag and cleans up code handling port lost indication to SCSI-ML.

qla2x00_configure_local_loop sets RELOGIN_NEEDED bit and calls qla24xx_fcport_handle_login to perform the login. This bit triggers a wake up of DPC later after a successful login. The deferred call is not needed if login succeeds, and it's set in qla24xx_fcport_handle_login in case of errors, hence it should be safe to drop.

2019-12-10scsi: qla2xxx: Configure local loop for N2N targetRoman Bolshakov1-8/+2
qla2x00_configure_local_loop initializes PLOGI payload for PLOGI ELS using Get Parameters mailbox command. In the case when the driver is running in target mode, the topology is N2N and the target port has higher WWPN, LOCAL_LOOP_UPDATE bit is cleared too early and PLOGI payload is not initialized by the Get Parameters command. That causes a failure of ELS IOCB carrying the PLOGI with 0x15 aka Data Underrun error. LOCAL_LOOP_UPDATE has to be set to initialize PLOGI payload.

2019-12-10scsi: qla2xxx: Allow PLOGI in target modeRoman Bolshakov1-2/+6
According to FC-LS-3 (Fibre Channel Link Services) 6.3.2.4 "N_Port Login - No Fabric present", if both parties in the point-to-point connection know N_Port_Names of each other, Nx_Port with the highest N_Port_name shall transmit PLOGI. The specification sets no restrictions on the port role that should send PLOGI. However, FCP-4 (Fibre Channel Protocol for SCSI, Fourth Version) 6.2 "Overview of Process Login and Process Logout", instructs that in point-to-point topology, initiator shall send explicit PRLI ELS. The change fixes stuck P2P login, when target WWPN is higher than initiator WWPN.

When a port sends PLOGI, discovery state should be changed to login pending, otherwise RELOGIN_NEEDED bit is set in qla24xx_handle_plogi_done_event(). RELOGIN_NEEDED triggers another PLOGI, and it never goes out of the loop until login timer expires.

2019-09-07scsi: qla2xxx: Fix stuck login sessionQuinn Tran1-12/+11
Login session was stucked on cable pull. When FW is in the middle PRLI PENDING + driver is in Initiator mode, driver fails to check back with FW to see if the PRLI has completed. This patch would re-check with FW again to make sure PRLI would complete before pushing forward with relogin.

2019-08-20scsi: qla2xxx: cleanup trace buffer initializationMartin Wilck1-116/+98
Avoid code duplication between qla2x00_alloc_offload_mem() and qla2x00_alloc_fw_dump() by moving the FCE and EFT buffer allocation and initialization to separate functions. Cleanly track failure and success by making sure that the ha->eft, ha->fce and respective eft_dma, fce_dma members are set if and only if the buffers are properly allocated and initialized. Avoid pointless buffer reallocation. Eliminate some goto statements. Make sure the fce_enabled flag is cleared when the FCE buffer is freed.

2019-08-08scsi: qla2xxx: Fix NVMe port discovery after a short device port lossArun Easi1-2/+2
The following sequence of event leads to NVME port disappearing: - device port shut - nvme_fc_unregister_remoteport - device port online - remote port delete completes - relogin is scheduled - "post gidpn" message appears due to rscn generation # mismatch In short, if a device comes back online sooner than an unregister completion, a mismatch in rscn generation number occurs, which is not handled correctly during device relogin. Fix this by starting with a redo of GNL. When ql2xextended_error_logging is enabled, the re-plugged device's discovery stops with the following messages printed: --8<-- qla2xxx [0000:41:00.0]-480d:3: Relogin scheduled. qla2xxx [0000:41:00.0]-4800:3: DPC handler sleeping. qla2xxx [0000:41:00.0]-2902:3: qla24xx_handle_relogin_event 21:00:00:24:ff:17:9e:91 DS 0 LS 7 P 0 del 2 cnfl (null) rscn 1|2 login 1|2 fl 1 qla2xxx [0000:41:00.0]-28e9:3: qla24xx_handle_relogin_event 1666 21:00:00:24:ff:17:9e:91 post gidpn qla2xxx [0000:41:00.0]-480e:3: Relogin end. --8<-- Signed-off-by: Arun Easi <aeasi@marvell.com> Signed-off-by: Himanshu Madhani <hmadhani@marvell.com> Signed-off-by: Martin K.
