Port issue was fixed, the hbacmd reset would take more than 8 minutes to
complete.
There were conflicting NVME SGL posting/reposting responsibilities
between lpfc_online()/lpfc_sli4_hba_setup() and
lpfc_nvme_create_localport(). The lpfc_online() causes a REPOST on
existing NVME SGLs which is not released during the fc port reset.
However, lpfc_nvme_create_localport() wants to allocate new NVME buffers
and post them. Both cancelled out each other which had a side effect of
hosing the mailbox handling that was used to remove the sgl lists -
causing multiple 60s mbx timeouts.
Fix by preserving all SGL lists over the fc port reset.

Various oops including cpu LOCKUPs were seen.
For asynchronously received ius where the driver must assign exchange
resources, the resources were on a single get (free) list and put list
(finished, waiting to be put on get list). As all cpus are sharing the
lists, an interrupt for a receive frame may have to wait for all the
other cpus to place their done work onto the put list before it can
acquire the lock to pull from the list.
Fix by breaking the resource lists into per-cpu lists or at least more
than 1 list with cpu's sharing the lists). A cpu would allocate from the
free list for its own cpu, and put its done work on the its own put list
- avoiding the contention. As cpu load may vary, when empty, a cpu may
grab from another cpu, thereby changing resource distribution. But
searching for a resource only occurs on 1 or a few cpus until a single
resource can be allocated. if the condition reoccurs, it starts looking
at a different cpu.

A race condition was found whereby the initiator would receive the RSCN

After lip, the driver sometimes would have two rports for the same

In lpfc_plogi_confirm_nport() the driver was not swapping the nrport

2nd rport to sneak in as it was considered a separate device.

After link bounce in a NVME Pt2Pt config, the driver managed to map the
same nport twice, resulting in multiple device nodes for the same
namespace.
In Pt2Pt, the driver must send PRLI's for both (scsi) FCP and NVME
rather than using fabric aids. The driver was inconsistent on handling
various PRLI completions, especially rejects, which had reject codes
cross the different protocol PRLI completions.
Fixed to perform the following: if nvmet mode (fc port can only be a
nvme target) - rejects all unsolicitly FCP PRLI's. Never issues a FCP
PRLI.
The multiple protocol PRLI's are sent simultaneously. However, driver
will now only state transition after both PRLI's are complete. New flags
were added to aid tracking the responses from the different PRLI's.

Modify driver return error codes to align with host nvme transport.

conditions returning -EBUSY.
Ensure the following situations return the proper return code:
- Temporary failures or temporary resource availability: -EBUSY
- Connectivity issues: -ENODEV
All others are treated as hard errors and return an -Exxx value that
indicates the type of error.
Also, lpfc_sli4_issue_wqe() was modified to not translate error from
-Exxx to WQE state. This allows lpfc_nvme_fcp_io_submit() routine to
just return whatever -E value was returned from other routines.

If there are IO's running and host reset or chip reset is triggered,
IO's can fail due to rport time out. During chip reset recovery process,
driver notifies the transport layer that remote port no longer exist, by
calling fc_remote_port_delete(). When this function is called, it
actually delays deletion by "blocking" it. It sets the remote port state
to "FC_PORTSTATE_BLOCKED" and sets FC_RPORT_DEVLOSS_PENDING. When
driver tries to abort the command by calling its abort handler function,
abort handler will wait until remote port state is blocked state or wait
for dev_loss_tmo time. Due to this blocking, rport times out and results
in an IO failure. This patch adds a check for any active reset process
before calling abort handler function.

Commit 1bc0eb0446 ("scsi: sg: protect accesses to 'reserved' page
array") adds needed concurrency protection for the "reserve" buffer.
Some checks that are initially made outside the lock are replicated once
the lock is taken to ensure the checks and resulting decisions are made
using consistent state.
The check that a request with flag SG_FLAG_MMAP_IO set fits in the
reserve buffer also needs to be performed again under the lock to ensure
the reserve buffer length compared against matches the value in effect
when the request is linked to the reserve buffer. An -ENOMEM should be
returned in this case, instead of switching over to an indirect buffer
as for non-MMAP_IO requests.

Currently in the driver the qedf_ctx attribute vlan_hw_insert is used to
which whether to insert a VLAN tag in FIP frames (except for FIP VLAN
request which is explicitly sent out untagged at least from the driver's
point of view).
When we receive a FIP VLAN response, we set qedf->vlan_hw_insert to 0 which
makes the qedf_fip_send function insert the VLAN. However when we exhaust
our FIP VLAN retries, we do not set qedf->vlan_hw_insert to 0 which means
that the driver will not tag the FIP frame with the correct VLAN ID. The
result that was observed on the wire is that some entity either in the LL2
or L2 firmware is adding a NULL VLAN tag which can cause FIP solicitation
to fail.
The offload FCoE frame function, qedf_xmit, does not use the vlan_hw_insert
attribute to decide whether to tag frames with the FIP/FCoE VLAN. Instead
it unilaterially tags the offload frames with the VLAN ID stored in
qedf->vlan_id. This is the correct behavior so the driver can guarantee
that non-offload FIP frames go out with the correct VLAN ID.
Also use the Linux network layer helpers instead of doing the VLAN insert
manually.
Also fix setting the fallback VLAN so that it used the module parameter and
is not hardcoded to 1002 (though 1002 is the default).

Currently in the driver we've been using the fc_fcoe_set_mac() function to
set the source MAC for FCoE traffic. This works well in most cases as it
uses the spec. default FCF-MAC. However, if the administrator changes the
FCF-MAC switch, then any FCoE traffic we send will be dropped by the
switch.
Instead we should check the granted MAC from the FLOGI payload and use that
address if it is present. Otherwise, fall back to using the the default
FCF-MAC and the fabric ID of the port as the FCoE MAC address.
Once this address is known we need to set it when doing non-offload
traffic, offload traffic and setting the data_src_address libfcoe uses for
FIP keep alive messages.

Releasing a zone write lock only when the write commnand that acquired
the lock completes can cause deadlocks due to potential command
reordering if the lock owning request is requeued and not executed. This
problem exists only with the scsi-mq path as, unlike the legacy path,
requests are moved out of the dispatch queue before being prepared and
so before locking a zone for a write command.
Since sd_uninit_cmnd() is now always called when a request is requeued,
call sd_zbc_write_unlock_zone() from that function for write requests
that acquired a zone lock instead of from sd_done(). Acquisition of a zone
lock by a write command is indicated using the new command
flag SCMD_ZONE_WRITE_LOCK.

This patch is a fix related to freeing a device in v2 hw driver.
Before, we polled to ITCT CLR interrupt to check if a device is free.
This was error prone, as if the interrupt doesn't occur in 10us, we miss
processing it.
To avoid this situation, service this interrupt and sync the event with
a completion.

This patch removes some repeated configurations:
(1) The device id of the device is already set in the alloc function, so
we don't need to modify in free device function.
(2) Field dev_type and dev_status are configured in hisi_sas_dev_gone(),
so there is no need for repeated config in free_device_v3_hw.

This patch provides fixes for the following issues:
1. Fix issue of controller reset required to send commands. For reset
process, it may be required to send commands to the controller, but
not during soft reset. So add HISI_SAS_NOT_ACCEPT_CMD_BIT to prevent
executing a task during this period.
2. Send a broadcast event in rescan topology to detect any topology
changes during reset.
3. Previously it was not ensured that libsas has processed the PHY up
and down events after reset. Potentially this could cause an issue
that we still process the PHY event after reset. So resolve this by
flushing shot workqueue in LLDD reset.
4. Port ID requires refresh after reset. The port ID generated after
reset is not guaranteed to be the same as before reset, so it needs
to be refreshed for each device's ITCT.

Add PQI reset to driver shutdown callback to work around controller bug.
During an 1.) OS shutdown or 2.) kexec outside of a kdump, the Linux
kernel will clear BME on our controller.
If BME is cleared during a controller/host PCIe transfer, the controller
will lock up.
So we perform a PQI reset in the driver's shutdown callback function to
eliminate the possibility of a controller/host PCIe transfer being
active when the kernel clears BME immediately after calling the driver's
shutdown callback.

In function pm8001_pci_probe(), on errors that the control flow jumps to
label err_out_ha_free, function pm8001_free() is called. In pm8001_free(),
scsi_host_put() is called to release shost, which keeps the return value
of scsi_host_alloc(). After pm8001_free() returns, kfree() is called to
free shost again, resulting in a double free bug. This patch removes
scsi_host_put() from pm8001_free() and explicitly calls scsi_host_put()
to release Scsi_Host in need.

Since this touches on a questionable ESP_INTR_DC conditional, add some
commentary to help others who may (as I did) find themselves chasing an
"Invalid Command" error after the device flags this condition.
This cleanup also eliminates a warning from "make W=1":
