dabc5ec915 scsi: qla2xxx: Don't defer relogin unconditonally
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.

fd1de5830a scsi: qla2xxx: Configure local loop for N2N target
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.

a9ed06d4e6 scsi: qla2xxx: Allow PLOGI in target mode
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.

58e39a2ce4 scsi: qla2xxx: Change discovery state before PLOGI
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.

edbd56472a scsi: qla2xxx: qla2x00_alloc_fw_dump: set ha->eft
In qla2x00_alloc_fw_dump(), an existing EFT buffer (e.g. from previous
invocation of qla2x00_alloc_offload_mem()) is freed.  The buffer is then
re-allocated, but without setting the eft and eft_dma fields to the new
values.

9e744591ef scsi: qla2xxx: Fix NVMe port discovery after a short device port loss
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.

e82f04ec6b scsi: qla2xxx: Fix possible fcport null-pointer dereferences
In qla2x00_alloc_fcport(), fcport is assigned to NULL in the error
handling code on line 4880:
    fcport = NULL;

Then fcport is used on lines 4883-4886:
    INIT_WORK(&fcport->del_work, qla24xx_delete_sess_fn);
	INIT_WORK(&fcport->reg_work, qla_register_fcport_fn);
	INIT_LIST_HEAD(&fcport->gnl_entry);
	INIT_LIST_HEAD(&fcport->list);

Thus, possible null-pointer dereferences may occur.

To fix these bugs, qla2x00_alloc_fcport() directly returns NULL
in the error handling code.

These bugs are found by a static analysis tool STCheck written by us.
