Drivers should do only device-specific jobs. But in general, drivers using
legacy PCI PM framework for .suspend()/.resume() have to manage many PCI
PM-related tasks themselves which can be done by PCI Core itself. This
brings extra load on the driver and it directly calls PCI helper functions
to handle them.
Switch to the new generic framework by updating function signatures and
define a "struct dev_pm_ops" variable to bind PM callbacks. Also, remove
unnecessary calls to the PCI Helper functions along with the legacy
.suspend & .resume bindings.

This patch reworks the abort interfaces such that SLI-3 retains the
iocb-based formatting and completions and SLI-4 now uses native WQEs and
completion routines.
The following changes are made:
- The code is refactored from a confusing 2 routine sequence of
xx_abort_iotag_issue(), which creates/formats and abort cmd, and
xx_issue_abort_tag(), which then issues and handles the completion of
the abort cmd - into a single interface of xx_issue_abort_iotag(). The
new interface will determine whether SLI-3 or SLI-4 and then call the
appropriate handler. A completion handler can now be specified to
address the differences in completion handling. Note: original code is
all iocb based, with SLI-4 converting to SLI-3 for the SCSI/ELS path,
and NVMe natively using wqes.
- The SLI-3 side is refactored:
The older iocb-base lpfc_sli_issue_abort_iotag() routine is combined
with the logic of lpfc_sli_abort_iotag_issue() as well as the
iocb-specific code in lpfc_abort_handler() and lpfc_sli_abort_iocb() to
create the new single SLI-3 abort routine that formats and issues the
iocb.
- The SLI-4 side is refactored and added to:
The native WQE abort code in NVMe is moved to the new SLI-4
issue_abort_iotag() routine. Items in SCSI that set fields not set by
NVMe is migrated into the new routine. Thus the routine supports NVMe
and SCSI initiators. The nvmet block (target) formats the abort slightly
different (like the old NVMe initiator) thus it has its own prep routine
stolen from NVMe initiator and it retains the current code it has for
issuing the WQE (does not use the commonized routine the initiators
do). SLI-4 completion handlers were also added.
- lpfc_abort_handler now becomes a wrapper that determines whether
SLI-3 or SLI-4 and calls the proper abort handler.

While testing initiator-side cable swaps with NPIV, oops occur. The
reference counts for the Fabric nodes on the NPIV vports isn't balanced,
resulting in premature node removal.
The following fixes were made:
- Removed the FC_LBIT check in lpfc_linkup_port. This removed the special
case for vports that didn't have them clean up just like the physical
port.
- Removed the unreg_rpi call in lpfc_cleanup_node. In this section, the
node is being removed in the context of a reference count release and a
mailbox command can't be issued at this point.
- Remove special case handling in the default mailbox completion handler
that allowed the skipping of a node reference. Now, reference counting
always requires the removal of the reference.
- Move the location of the DEVICE_RM event is done during LOGO handling as
the driver has additional work to do on the ndlp before puts/releases
can be performed.

While testing NPIV and link bounces, the vport would not show a fabric node
for the F_Port, would not transition into NPR state during a link fault, or
leave the FDMI node untouched during error injection. Cause for this was
determined to be an inconsistent manner in which F_Port, Nameserver, and
FDMI controller nodes were created and linked. In some cases, the nodes
would never be unregistered from the transport, leaving references
active. In other cases, the fabric nodes may register with the transport
multiple times while still registered.
The following changes were made:
- Fix the FDISC issue routine, which starts vport (re)creation, to mark
the F_Port as a fabric node (NLP_FABRIC) and allow the F_Port node to
fully be created and show up in the node list.
- When remote ports are cleaned up on vport termination, cleanup the
nameserver and FDMI controller nodes on the vport so they unregister
from the transport.
- On link bounces, don't exclude the NPIV Fabric remote ports from
transitioning to the NPR state, allowing them to avoid re-registration
if already registered.

When a target swap happens, under certain conditions the node sends a
LOGO. The unsolicited ELS logic responds with a reject. The logic may
allocate a new node to handle this. Afterward, the new nodes are dropped
incorrectly leaving them in a mis-matched state and refcounting causes a
use-after-free situation leading to a crash.
It is also possible that the unsolicited els handling finds a node which is
in an UNUSED state. The handling moves these nodes to NPR state with a
refcount of 1. Although the end of the discovery logic assumes a final put
will free such a node, there are codes paths which could increment the
reference count, thus the node is in NPR state and not released.
Eventually this mismatch in state and refcount leads to premature release
of the node causing a crash.
Fix by always using the discovery engine DEVICE RM event to decrement and
release the nodes (rather than explicit code that tried to do it before).
This will take care of moving the node to the UNUSED state and then removes
the final ref count. If there is a trigger to reuse this node, the
transition from the UNUSED state clearly indicates that the initial
reference is then incremented and use can continue.

When a PLOGI/ADISC/PRLI/REG_RPI fails, the node remains in the nodelist in
that state. Although the driver now frees a node when the ref count goes
to zero, in this case the ref cnt doesn't reach zero because there isn't a
mechanism to release the final reference. Discovery just stops.
Fix by calling the node discovery state machine DEVICE_RM event whenever
one of these commands fail. This will remove the final reference count and
trigger node release.

Due to bug history and code review, the node reference counting approach in
the driver isn't implemented consistently with how the scsi and nvme
transport perform registrations and unregistrations and their callbacks.
This resulted in many bad/stale node pointers.
Reword the driver so that reference handling is performed as follows:
- The initial node reference is taken on structure allocation
- Take a reference on any add/register call to the transport
- Remove a reference on any delete/unregister call to the transport
- After the node has fully removed from both the SCSI and NVMEe transports
(dev_loss_callbacks have called back) call the discovery engine
DEVICE_RM event which will remove the final reference and release the
node structure.
- Alter dev_loss handling when a vport or base port is unloading.
- Remove the put_node handling - no longer needed.
- Rewrite the vport_delete handling on reference counts. Part of this
effort was driven from the FDISC not registering with the transport and
disrupting the model for node reference counting.
- Deleted lpfc_nlp_remove. Pushed it's remaining ops into
lpfc_nlp_release.
- Several other small code cleanups.

The lpfc driver is calling get_device and put_device on scsi_fc_transport
device structure. When this code was removed, the driver triggered an oops
in "scsi_is_host_dev" when the first SCSI target was unregistered from the
transport.
The reason the calls were necessary is that the driver is calling
scsi_remove_host too early, before the target rports are unregistered and
the scsi devices disconnected from the scsi_host. The fc_host was torn
down during fc_remove_host.
Fix by moving the lpfc_pci_remove_one_s3/s4 calls to scsi_remove_host to
after the nodes are cleaned up. Remove the get_device and put_device calls
and the supporting code.

Now that the driver has gone to a normal ref interface (with no odd logic)
the discovery logic needs to be updated to reworked so that it properly
takes references when it should and give them up when it should.
Rework the driver for the following get/put model:
- Move gets to just before an I/O is issued. Add gets for places where an
I/O was issued without one.
- Ensure that failures from lpfc_nlp_get() are handled by the driver.
- Check and fix the placement of lpfc_nlp_puts relative to io completions.
Note: some of these paths may not release the reference on the exact io
completion as the reference is held as the code takes another step in
the discovery thread and which may cause another io to be issued.
- Rearrange some code for error processing and calling lpfc_nlp_put.
- Fix some places of incorrect reference freeing that was causing the
premature releasing of the structure.
- Nvmet plogi handling performs unreg_rpi's. The reference counts were
unbalanced resulting in premature node removal. In some cases this
caused loss of node discovery. Corrected the reftaking around nvmet
plogis.
Nodes that experience devloss now get released from the node list now that
there is a proper reference taking.

When a remote port is disconnected and disappears, its node structure
(ndlp) stays allocated and on a vport node list. While on the list it can
be matched, thus requires validation checks on state to be added in
numerous code paths. If the node comes back, its possible for there to be
multiple node structures for the same device on the vport node list. There
is no reason to keep the node structure around after it is no longer in
existence, and the current implementation creates problems for itself
(multiple nodes) and lots of unnecessary code for state validation.
Additionally, the reference taking on the node structure didn't follow the
normal model used by the kernel kref api. It included lots of odd logic to
match state with reference count. The combination of this odd logic plus
the way it was implicitly used in the discovery engine made its reference
taking implementation suspect and extremely hard to follow.
Change the driver such that the reference taking routines are now normal
ref increments/decrements and callout on refcount=0.
With this in place, the rework can be done such that the node structure is
fully removed and deallocated when the remote port no longer exists and all
references are removed. This removal logic, and the basic ref counting are
intrically tied, thus in a single patch.

Now that MIB support was registered with FDMI, the driver may receive CT
requests for MIB-related commands. At this time, no command is
supported. However, the driver needs to be graceful and reject the CT
request.
This patch adds identification of the requests as well as sending the
reject response.

Created new attribute lpfc_enable_mi, which by default is enabled.
Add command definition bits for SLI-4 parameters that recognize whether the
adapter has MIB information support and what revision of MIB data. Using
the adapter information, register vendor-specific MIB support with FDMI.
The registration will be done every link up.
During FDMI registration, encountered a couple of errors when reverting to
FDMI rev1. Code needed to exist once reverting. Fixed these.

The driver supports arbitrarily large scatter-gather lists and the current
value for max_sectors is limiting.
Change max_sectors to the largest value. This was actually done prior but
it only corrected one template and that template was later removed.
So change the remaining 2 templates. Other areas which hard-set the sectors
value should be inheriting what is in the template.

Commit 9816ef6ecb ("scsi: lpfc: Use after free in lpfc_rq_buf_free()")
was made to correct a use after free condition in lpfc_rq_buf_free().
Unfortunately, a subsequent patch cut on a tree without the fix
inadvertently reverted the fix.
Put the fix back: Move the freeing of the rqb_entry to after the print
function that references it.

With the conversion to blk_io_poll for better interrupt latency in normal
cases, it introduced this code path, executed when I/O aborts or logouts
are seen, which attempts to allocate memory for a mailbox command to be
issued. The allocation is GFP_KERNEL, thus it could attempt to sleep.
Fix by creating a work element that performs the event handling for the
remote port. This will have the mailbox commands and other items performed
in the work element, not the irq. A much better method as the "irq" routine
does not stall while performing all this deep handling code.
Ensure that allocation failures are handled and send LOGO on failure.
Additionally, enlarge the mailbox memory pool to reduce the possibility of
additional allocation in this path.
