DID_TARGET_FAILURE is internal to the SCSI layer. Drivers must not use it
because:
1. It's not propagated upwards, so SG IO/passthrough users will not see an
error and think a command was successful.
2. There is no handling for it in scsi_decide_disposition() so it
results in entering SCSI error handling.
This has qla2xxx use DID_NO_CONNECT because it looks like we hit this error
when we can't find a port. It will give us the same hard error behavior and
it seems to match the error where we can't find the endpoint.

Older tracing of driver messages was to:
- log only debug messages to kernel main trace buffer; and
- log only if extended logging bits corresponding to this message is
off
This has been modified and extended as follows:
- Tracing is now controlled via ql2xextended_error_logging_ktrace
module parameter. Bit usages same as ql2xextended_error_logging.
- Tracing uses "qla2xxx" trace instance, unless instance creation have
issues.
- Tracing is enabled (compile time tunable).
- All driver messages, include debug and log messages are now traced in
kernel trace buffer.
Trace messages can be viewed by looking at the qla2xxx instance at:
/sys/kernel/tracing/instances/qla2xxx/trace
Trace tunable that takes the same bit mask as ql2xextended_error_logging
is:
ql2xextended_error_logging_ktrace (default=1)

This message is helpful to troubleshoot missing LUNs/SAN boot errors. It'd
be nice to log it by default instead of only being enabled with debug.
This user had an accidental/forgotten file modprobe.d/qla2xxx.conf w/
option qlini_mode=disabled from experiments with FC target mode, and their
boot LUN didn't come up, as it skips SCSI scan, of course.
However, their boot log didn't provide any clues to help understand that.
The issue/message could be figured out w/ ql2xextended_error_logging, but
it would have been simpler (or even deflected/addressed by user) if it had
been there by default. And it also would help support/triage/deflection

limiting reading packets until the IN pointer.
Two module parameters are introduced:
ql2xrspq_follow_inptr:
When set, on newer adapters that has queue pointer shadowing, look for
response packets only until response queue in pointer.
When reset, response packets are read based on a signature pattern
logic (old way).
ql2xrspq_follow_inptr_legacy:
Like ql2xrspq_follow_inptr, but for those adapters where there is no
queue pointer shadowing.

User experience slow recovery when target device went through a stop/start
of the authentication application (app_stop/app_start).
Between the period of app_stop and app_start on the target device, target
device choose to send ELS Reject for any receive AUTH ELS command. At this
time, authentication application does not do ELS reject if it encounters
error.
Therefore, AUTH ELS reject signify authentication application is not
running. If driver passes up the AUTH ELS Reject to the authentication
application, then it would result in authentication application
retrying/resending the same AUTH ELS command again + delay.
As a work around, driver should trigger a session tear down where it tells
the local authentication application to also tear down. At the next
relogin, both sides are then synchronized.

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. Due to N2N, the PRLI [nvme | fcp] can
fail because of the mode mismatch with target. This patch add a few more
login retries to revive the connection.

Aborting commands that have already been sent to the firmware can
cause BUG in qlt_free_cmd(): BUG_ON(cmd->sg_mapped)
For instance:
- Command passes rdx_to_xfer state, maps sgl, sends to the firmware
- Reset occurs, qla2xxx performs ISP error recovery, aborts the command
- Target stack calls qlt_abort_cmd() and then qlt_free_cmd()
- BUG_ON(cmd->sg_mapped) in qlt_free_cmd() occurs because sgl was not
unmapped
Thus, unmap sgl in qlt_abort_cmd() for commands with the aborted flag set.

because driver thinks a recovery is in progress for this session. In

session deletion got in front of this call due to link perturbation.

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.

Instead of using the SCp.ptr field to track whether or not a command is
in flight, use the sp->type field to track this information. sp->type
must be set for proper operation of the qla2xxx driver. See e.g. the
switch (sp->type) statement in qla2x00_ct_entry().
This patch prepares for removal of the SCSI pointer from struct scsi_cmnd.

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.

The timeout handler and the done function are racing. When
qla2x00_async_iocb_timeout() starts to run it can be preempted by the
normal response path (via the firmware?). qla24xx_async_gpsc_sp_done()
releases the SRB unconditionally. When scheduling back to
qla2x00_async_iocb_timeout() qla24xx_async_abort_cmd() will access an freed
sp->qpair pointer:

BUG: unable to handle kernel NULL pointer dereference at 0000000000000004
IP: qla24xx_async_abort_cmd+0x1b/0x1c0 [qla2xxx]
Obvious solution to this is to introduce a reference counter. One reference
is taken for the normal code path (the 'good' case) and one for the timeout
path. As we always race between the normal good case and the timeout/abort
handler we need to serialize it. Also we cannot assume any order between
the handlers. Since this is slow path we can use proper synchronization via
locks.
When we are able to cancel a timer (del_timer returns 1) we know there
can't be any error handling in progress because the timeout handler hasn't
expired yet, thus we can safely decrement the refcounter by one.
If we are not able to cancel the timer, we know an abort handler is
running. We have to make sure we call sp->done() in the abort handlers
before calling kref_put().

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

...when device side port resets were done.
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.

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.

On completion of the authentication process, the authentication application
will notify driver on whether it is successful or not.
In case of success, application will use the QL_VND_SC_AUTH_OK BSG call to
tell driver to proceed to the PRLI phase.
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.

Target de-configuration panics at high CPU load because TPGT and WWPN can
be removed on separate threads.
TPGT removal requests a reset HBA on a separate thread and waits for reset
complete (phase1). Due to high CPU load that HBA reset can be delayed for
some time.
WWPN removal does qlt_stop_phase2(). There it is believed that phase1 has
already completed and thus tgt.tgt_ops is subsequently cleared. However,
tgt.tgt_ops is needed to process incoming traffic and therefore this will
cause one of the following panics:
NIP qlt_reset+0x7c/0x220 [qla2xxx]
LR qlt_reset+0x68/0x220 [qla2xxx]

The patch fixes the issue by serializing qlt_stop_phase1() and
qlt_stop_phase2() functions to make WWPN removal wait for phase1
completion.

In a case when the initiator in P2P mode by some circumstances does not
send PRLI, the target, in a case when the target port's WWPN is less than
initiator's, changes the discovery state in DSC_GNL. When gnl completes it
sends PRLI to the initiator.
Usually the initiator in P2P mode always sends PRLI. We caught this issue
on Linux stable v5.4.6 https://www.spinics.net/lists/stable/msg458515.html.
Fix this particular corner case in the behaviour of the P2P mod target
login state machine.

Commit a6dcfe0848 ("scsi: qla2xxx: Limit interrupt vectors to number of
CPUs") lowers the number of allocated MSI-X vectors to the number of CPUs.
That breaks vector allocation assumptions in qla83xx_iospace_config(),
qla24xx_enable_msix() and qla2x00_iospace_config(). Either of the functions
computes maximum number of qpairs as:
ha->max_qpairs = ha->msix_count - 1 (MB interrupt) - 1 (default
response queue) - 1 (ATIO, in dual or pure target mode)
max_qpairs is set to zero in case of two CPUs and initiator mode. The
number is then used to allocate ha->queue_pair_map inside
qla2x00_alloc_queues(). No allocation happens and ha->queue_pair_map is
left NULL but the driver thinks there are queue pairs available.
qla2xxx_queuecommand() tries to find a qpair in the map and crashes:
if (ha->mqenable) {
uint32_t tag;
uint16_t hwq;
struct qla_qpair *qpair = NULL;
tag = blk_mq_unique_tag(cmd->request);
hwq = blk_mq_unique_tag_to_hwq(tag);
qpair = ha->queue_pair_map[hwq]; # <- HERE
if (qpair)
return qla2xxx_mqueuecommand(host, cmd, qpair);
}

The driver should allocate enough vectors to provide every CPU it's own HW
queue and still handle reserved (MB, RSP, ATIO) interrupts.
The change fixes the crash on dual core VM and prevents unbalanced QP
allocation where nr_hw_queues is two less than the number of CPUs.

- qlt_xmit_response() calls qlt_check_reserve_free_req()
- qlt_check_reserve_free_req() returns -EAGAIN
- qlt_xmit_response() calls vha->hw->tgt.tgt_ops->free_cmd(cmd)

tcm_loop could be used like a normal block device, so we can't use
GFP_KERNEL and should use GFP_NOIO. This adds a gfp_t arg to
target_cmd_init_cdb() and converts the users. For every driver but loop
GFP_KERNEL is kept.
This will also be useful in subsequent patches where loop needs to do
target_submit_prep() from interrupt context to get a ref to the se_device,
and so it will need to use GFP_ATOMIC.

target_submit_cmd() is now only for simple drivers that do their
own sync during shutdown and do not use target_stop_session().
tcm_qla2xxx uses target_stop_session() to sync session shutdown with LIO
core, so we use target_init_cmd()/target_submit_prep()/target_submit(),
because target_init_cmd() will detect the target_stop_session() call and
return an error.
