When a FLOGI completes with a sequence timeout error, a freed kref ptr
dereference crash can occur due to a timing race involving ndlp referencing
in lpfc_dev_loss_tmo_callbk.
Fix by ensuring the driver accounts for an outstanding FLOGI when dev_loss
is active. Also, don't remove the HBA_FLOGI_OUTSTANDING flag when the
FLOGI is retried to allow the driver to handle the reference counts
correctly in lpfc_dev_loss_tmo_handler.

The lpfc_cmf_timer adjusts phba->cmf_link_byte_count periodically and can

During bandwidth calculation, correct for this by setting a cap of logging

Adapter configurations with limited EQ resources may fail to initialize.
Firmware resources are queried in lpfc_sli4_read_config(). The driver
parameters cfg_irq_chann and cfg_hdw_queue are adjusted from defaults if
constrained by firmware resources.
The minimum resource check includes a special allocation for queues such as
ELS, MBOX, NVME LS. However the additional reservation was also incorrectly
applied to EQ resources.
Reordered WQ|CQ|EQ resource checks to apply the special allocation
adjustment to WQ and CQ resources only.

Commit 5e633302ac ("scsi: lpfc: vmid: Add support for VMID in mailbox
command") introduced allocations for the VMID resources in
lpfc_create_port() after the call to scsi_host_alloc(). Upon failure on the
VMID allocations, the new code would branch to the 'out' label, which
returns NULL without unwinding anything, thus skipping the call to
scsi_host_put().
Fix the problem by creating a separate label 'out_free_vmid' to unwind the
VMID resources and make the 'out_put_shost' label call only
scsi_host_put(), as was done before the introduction of allocations for
VMID.

structure defines instead of living in a union. This rids of ambiguous
compiler zero padding, and entailed cleaning up bitwise endian
declarations.

void *arg and handlers for each of the newly defined attribute structure
types.

On a PCI hotplug capable system, it is possible for scsi_device_put() to
happen after lpfc_pci_remove_one() is called. As a result, the
sdev->host->hostt->module dereference is for a previously freed memory
location because the phba structure containing the hostt template was
already freed when lpfc_pci_remove_one() returned.
Since the lpfc module is still loaded during power slot disable, all
scsi_host_templates should be declared as part of the global data segment
instead of inside the heap allocated phba structure. This way the
sdev->host->hostt memory area is always valid as long as the module is
loaded regardless if PCI hotplug dynamically allocates or frees phba
structures.
Move all scsi_host_templates in the phba structure to global variables.
Create a small helper routine to determine appropriate sg_tablesize during
shost allocation.

Sometimes VMID targets are not getting rediscovered after a port reset.
The iocb is not freed in lpfc_cmpl_ct_cmd_vmid(), which is the completion
function for the appid CT commands. So after a port reset, the count of
sges is less than the expected count of 250. This causes post reset
operation logic to fail and keep the port offline.
Fix by freeing the iocb and kref put for the lpfc_cmpl_ct_cmd_vmid() early
return cases.

When a FLOGI is received before we have issued our FLOGI, the ACC response
to the received FLOGI is issued with SID 2 instead of the expected fabric
controller SID. Certain target vendors ignore the malformed ACC with SID 2
and wait for a properly filled ACC with a fabric controller SID.
The lpfc_sli_prep_wqe() routine depends on the FC_PT2PT flag to fill in the
fabric controller SID when in PT2PT mode, but due to a previous commit the
flag was getting cleared. Fix by adding a check for the defer_flogi_acc
flag to know whether or not to clear the FC_PT2PT flag on link up.

When the driver hits an internal error condition returning DID_REQUEUE the
I/O will be retried on the same ITL nexus. This will inhibit multipathing,
resulting in endless retries even if the error could have been resolved by
using a different ITL nexus. Return DID_TRANSPORT_DISRUPTED to allow for
multipath to engage and route I/O to another ITL nexus.

The kernel test robot reported the following sparse warning:
arch/arm64/include/asm/cmpxchg.h:88:1: sparse: sparse: cast truncates
bits from constant value (369 becomes 69)
On arm64, atomic_xchg only works on 8-bit byte fields. Thus, the macro
usage of LPFC_RXMONITOR_TABLE_IN_USE can be unintentionally truncated
leading to all logic involving the LPFC_RXMONITOR_TABLE_IN_USE macro to not
work properly.
Replace the Rx Table atomic_t indexing logic with a new
lpfc_rx_info_monitor structure that holds a circular ring buffer. For
locking semantics, a spinlock_t is used.

During a stress offline/online test in PT2PT topology, target rediscovery
can fail with a specific target vendor array.
When the HBA transitions to online mode it is possible to receive an
unsolicited FLOGI before processing the Link Up event. The received FLOGI
will set the defer_flogi_acc_flag, which instructs the driver to wait until
it transmits its own FLOGI before ACKing the received FLOGI. In this
failure scenario, the link up processing clears the set
defer_flogi_acc_flag before we have sent out the FLOGI. As the target has
the higher WWPN and is responsible for sending the PLOGI, the target is
stuck waiting for its FLOGI_ACC that the driver will never send.
Remove the clear of defer_flogi_acc_flag from Link Up event processing. In
this stress test case, the defer_flogi_acc_flag is cleared during the Link
Down event processing anyways.

The RSCN_MEMENTO logic was to workaround a target that does not register
both FCP and NVMe FC4 types at the same time. This caused the
configuration to not produce a second RSCN for the NVMe FC4 type
registration in a timely manner. The intention of the RSCN_MEMENTO flag
was to always signal to try NVMe PRLI.
However, there are other FCP-only target arrays in correctly behaved
configurations that reject the NVMe PRLI followed by a LOGO leading to
never rediscovering the target after an issue_lip (as LOGO causes a repeat
of PLOGI/PRLIs).
Revert the RSCN_MEMENTO patch as it is causing correctly behaved configs to
fail while it exists only to succeed on a misbehaved config.

During a target link bounce test, the driver sees a mismatch between the
NPortId and the WWPN on the node structures (ndlps) involved. When this
occurs, the driver "swaps" the ndlp and new_ndlp node parameters to restore
WWPN/DID uniqueness in the fc_nodes list per vport. However, the driver
neglected to swap the nlp_fc4_type in the ndlp passed to
lpfc_plogi_confirm_nport causing a failure to recover the NVMe PLOGI/PRLI
and ultimately the NVMe paths.
Correct confirm_nport to preserve the fc4 types from the new-ndlp when the
data is moved over ot the ndlp structure.
