It's basically driver updates to lpfc, target, bnx2fc and ufs with the
rest being minor updates except the sr_block_release one which fixes a
use after free introduced by the removal of the global mutex in the
first patch set"

The original patch was to resolve the lldd being able to be unloaded
while being used to talk to the boot device of the system. However, the
end result of the original patch is that any driver unload while a nvme
controller is live via the lldd is now being prohibited. Given the module
reference, the module teardown routine can't be called, thus there's no
way, other than manual actions to terminate the controllers.

The default lun queue depth by the driver has been 30 for many years.
However, this value, when used with more recent hardware, has actually
throttled some tests that concentrate io on a lun.
Increase the default lun queue depth to 64.
Queue full handling, reported by the target, remains in effect and
unchanged.

The cpu io statistics were capped by a hard define limit of 128. This
effectively was a max number of CPUs, not an actual CPU count, nor actual
CPU numbers which can be even larger than both of those values. This made
stats off/misleading and on large CPU count systems, wrong.
Fix the stats so that all CPUs can have a stats struct. Fix the looping
such that it loops by hdwq, finds CPUs that used the hdwq, and sum the
stats, then display.

The AER interfaces to clear error status registers were a confusing mess:
- pci_cleanup_aer_uncorrect_error_status() cleared non-fatal errors
from the Uncorrectable Error Status register.
- pci_aer_clear_fatal_status() cleared fatal errors from the
Uncorrectable Error Status register.
- pci_cleanup_aer_error_status_regs() cleared the Root Error Status
register (for Root Ports), the Uncorrectable Error Status register,
and the Correctable Error Status register.
Rename them to make them consistent:
From To
---------------------------------------- -------------------------------
pci_cleanup_aer_uncorrect_error_status() pci_aer_clear_nonfatal_status()
pci_aer_clear_fatal_status() pci_aer_clear_fatal_status()
pci_cleanup_aer_error_status_regs() pci_aer_clear_status()
Since pci_cleanup_aer_error_status_regs() (renamed to
pci_aer_clear_status()) is only used within drivers/pci/, move the
declaration from <linux/aer.h> to drivers/pci/pci.h.

The lpfc_sli4_wq_release() routine iterates for each interim value when
updating the wq consuemr index. This wastes cycles and possibly confuses
things as thevalue itterates (and the modulo logic is being applied).
There's no reason for this. Just set it to the value from the hw.

Injecting EEH on a 32GB card is causing kernel oops
The pci error handler is doing an IO flush and the offline code is also
doing an IO flush. When the 1st flush is complete the hdwq is destroyed
(freed), yet the second flush accesses the hdwq and crashes.
Added a check in lpfc_sli4_fush_io_rings to check both the HBA_IOQ_FLUSH
flag and the hdwq pointer to see if it is already set and not already
freed.

SCSI layer sends driver IOs with more s/g segments than driver can handle.
This results in "Too many sg segments from dma_map_sg. Config 64, seg_cnt
219" error messages from the lpfc_scsi_prep_dma_buf_s3() routine.
The was due to use the driver using individual templates for pport and
vport, host reset enabled or not, nvme vs scsi, etc. In the end, there was
a combination for a vport that didn't match the pport.
Rather than enumerating more templates and more discretionary assignments,
revert to a base template that is copied to a template specific to the
pport/vport. Then, based on role, attributes and sli type, modify the
fields that are different for that port. Added a log message to
lpfc_create_port to validate values.

In lpfc_nvmet_prep_fcp_wqe() the line "rsp->sg_cnt = 0" is modifying the
transport's data structure. This may result in the transport believing the
s/g list was already freed, thus may not unmap/free it properly. Lpfc
driver should not modify the transport data structure.
The zeroing of the sg_cnt is to avoid use of the transport's sgl in a
subsequent loop where the driver builds the necessary requests for the
adapter firmware to complete the IO.
Change LLDD to use a local copy of the transport sg_cnt when building
requests to be passed to the adapter fw.

When processing the completion of a "Reg Rpi" login mailbox command in
lpfc_sli_def_mbox_cmpl, a call may be made to lpfc_unreg_login. The vpi is
extracted from the completing mailbox context and passed as an input for
the next. However, the vpi stored in the mailbox command context is an
absolute vpi, which for SLI4 represents both base + offset. When used with
a non-zero base component, (function id > 0) this results in an
out-of-range access beyond the allocated phba->vpi_ids array.
Fix by subtracting the function's base value to get an accurate vpi number.

This patch modifies lpfc to register for Link Integrity events via the use
of an RDF ELS and to perform Link Integrity FPIN logging.
Specifically, the driver was modified to:
- Format and issue the RDF ELS immediately following SCR registration.
This registers the ability of the driver to receive FPIN ELS.
- Adds decoding of the FPIN els into the received descriptors, with
logging of the Link Integrity event information. After decoding, the ELS
is delivered to the scsi fc transport to be delivered to any user-space
applications.
- To aid in logging, simple helpers were added to create enum to name
string lookup functions that utilize the initialization helpers from the
fc_els.h header.
- Note: base header definitions for the ELS's don't populate the
descriptor payloads. As such, lpfc creates it's own version of the
structures, using the base definitions (mostly headers) and additionally
declaring the descriptors that will complete the population of the ELS.

There was report of an odd "Fix me..." log message, which was tracked down
to the lpfc_els_rcv_rps() routine. This was in handling of a very old and
obsolete ELS - Read Port Status. The RPS ELS was defined in FC-LS-1, but
deprecated in FC-LS-2, and removed from all later FC-LS revisions. It was
replaced by the Read Diagnostic Parameters (RDP) ELS and the Link Error
Status Block descriptor.
There should be no support for the RSP ELS. Remove support from driver.

CID 15768 [Memory Corruption] Out-of-bounds access on FDMI
Sloppy coding of the fmdi structures. In both the lpfc_fdmi_attr_def and
lpfc_fdmi_reg_port_list structures, a field was placed at the start of
payload that may have variable content. The field was given an arbitrary
type (uint32_t). The code then uses the field name to derive an address,
which it used in things such as memset and memcpy. The memset sizes or
memcpy lengths were larger than the arbitrary type, thus coverity reported
an error.
Fix by replacing the arbitrary fields with the real field structures
describing the payload.

When performing reset testing, the eq's list for related hwqs was getting
corrupted. In cases where there is not a 1:1 eq to hwq, the eq is
shared. The eq maintains a list of hwqs utilizing it in case of cpu
offlining and polling. During the reset, the hwqs are being torn down so
they can be recreated. The recreation was getting confused by seeing a
non-null eq assignment on the eq and the eq list became corrupt.
Correct by clearing the hdwq eq assignment when the hwq is cleaned up.

When driver is set to enable bb credit recovery, the switch displayed the
setting as inactive. If the link bounces, it switches to Active.
During link up processing, the driver currently does a MBX_READ_SPARAM
followed by a MBX_CONFIG_LINK. These mbox commands are queued to be
executed, one at a time and the completion is processed by the worker
thread. Since the MBX_READ_SPARAM is done BEFORE the MBX_CONFIG_LINK, the
BB_SC_N bit is never set the the returned values. BB Credit recovery status
only gets set after the driver requests the feature in CONFIG_LINK, which
is done after the link up. Thus the ordering of READ_SPARAM needs to follow
the CONFIG_LINK.
Fix by reordering so that READ_SPARAM is done after CONFIG_LINK. Added a
HBA_DEFER_FLOGI flag so that any FLOGI handling waits until after the
READ_SPARAM is done so that the proper BB credit value is set in the FLOGI
payload.

The driver is occasionally seeing the following SLI Port error, requiring
reset and reinit:
Port Status Event: ... error 1=0x52004a01, error 2=0x218
The failure means an RQ timeout. That is, the adapter had received
asynchronous receive frames, ran out of buffer slots to place the frames,
and the driver did not replenish the buffer slots before a timeout
occurred. The driver should not be so slow in replenishing buffers that a
timeout can occur.
When the driver received all the frames of a sequence, it allocates an IOCB
to put the frames in. In a situation where there was no IOCB available for
the frame of a sequence, the RQ buffer corresponding to the first frame of
the sequence was not returned to the FW. Eventually, with enough traffic
encountering the situation, the timeout occurred.
Fix by releasing the buffer back to firmware whenever there is no IOCB for
the first frame.

Pull compat_ioctl cleanup from Arnd. Here's his description:
This series concludes the work I did for linux-5.5 on the compat_ioctl()
cleanup, killing off fs/compat_ioctl.c and block/compat_ioctl.c by moving
everything into drivers.
Overall this would be a reduction both in complexity and line count, but
as I'm also adding documentation the overall number of lines increases
in the end.
My plan was originally to keep the SCSI and block parts separate.
This did not work easily because of interdependencies: I cannot
do the final SCSI cleanup in a good way without first addressing the
CDROM ioctls, so this is one series that I hope could be merged through
either the block or the scsi git trees, or possibly both if you can
pull in the same branch.
The series comes in these steps:
1. clean up the sg v3 interface as suggested by Linus. I have
talked about this with Doug Gilbert as well, and he would
rebase his sg v4 patches on top of "compat: scsi: sg: fix v3
compat read/write interface"
2. Actually moving handlers out of block/compat_ioctl.c and
block/scsi_ioctl.c into drivers, mixed in with cleanup
patches
3. Document how to do this right. I keep getting asked about this,
and it helps to point to some documentation file.
The branch is based on another one that fixes a couple of bugs found
during the creation of this series.
Changes since v3:
https://lore.kernel.org/lkml/20200102145552.1853992-1-arnd@arndb.de/
- Move sr_compat_ioctl fixup to correct patch (Ben Hutchings)
- Add Reviewed-by tags
Changes since v2:
https://lore.kernel.org/lkml/20191217221708.3730997-1-arnd@arndb.de/
- Rebase to v5.5-rc4, which contains the earlier bugfixes
- Fix sr_block_compat_ioctl() error handling bug found by
Ben Hutchings
- Fix idecd_locked_compat_ioctl() compat_ptr() bug
- Don't try to handle HDIO_DRIVE_TASKFILE in drivers/ide
- More documentation improvements
Changes since v1:
https://lore.kernel.org/lkml/20191211204306.1207817-1-arnd@arndb.de/
- move out the bugfixes into a branch for itself
- clean up scsi sg driver further as suggested by Christoph Hellwig
- avoid some ifdefs by moving compat_ptr() out of asm/compat.h
- split out the blkdev_compat_ptr_ioctl function; bug spotted by

When running Cisco-MDS diagnostics which perform driver-level frame loop
back, the switch is reporting errors. Diagnostic has a limit on latency
that is not being met by the driver.
The requirement of Latency frames is that they should be responded back by
the host with a maximum delay of few hundreds of microseconds. If the
switch doesn't get response frames within this time frame, it fails the
test.
Test is failing as the lpfc-wq workqueue was overwhelmed by the packet rate
and in some cases, the work element yielded to other kernel elements.
To resolve, reduce the outstanding load allowed by the adapter. This
ensures the driver spends a reasonable amount of time doing loopback and
can do so such that latency values can be met. Load is managed by reducing
the number of receive buffers posted such that the link can be
backpressured to reduce load.

There are reports of multiple ports on the same system displaying different
hostnames in fabric FDMI displays.
Currently, the driver registers the hostname at initialization and obtains
the hostname via init_utsname()->nodename queried at the time the FC link
comes up. Unfortunately, if the machine hostname is updated after
initialization, such as via DHCP or admin command, the value registered
initially will be incorrect.
Fix by having the driver save the hostname that was registered with FDMI.
The driver then runs a heartbeat action that will check the hostname. If
the name changes, reregister the FMDI data.
The hostname is used in RSNN_NN, FDMI RPA and FDMI RHBA.

When the WriteObject mailbox response has change_status set to is 0x2
(Firmware Reset) or 0x04 (Port Migration Reset), the CSF field should also
be checked to see if a fw reset is sufficient to enable all new features in
the updated firmware image. If not, a fw reset would start the new
firmware, but with a feature level equal to existing firmware. To enable
the new features, a chip reset/pci slot reset would be required.
Check the CSF bit when change_status is 0x2 or 0x4 to know whether to
perform a pci bus reset or fw reset.

NVMe device re-discovery does not complete. Dev_loss_tmo messages seen on
initiator after recovery from a link disturbance.
The failing case is the following:
When the driver (as a NVME target) receives a PLOGI, the driver initiates
an "unreg rpi" mailbox command. While the mailbox command is in progress,
the driver requests that an ACC be sent to the initiator. The target's ACC
is received by the initiator and the initiator then transmits a PLOGI. The
driver receives the PLOGI prior to receiving the completion for the PLOGI
response WQE that sent the ACC. (Different delivery sources from the hw so
the race is very possible). Given the PLOGI is prior to the ACC completion
(signifying PLOGI exchange complete), the driver LS_RJT's the PRLI. The
"unreg rpi" mailbox then completes. Since PRLI has been received, the
driver transmits a PLOGI to restart discovery, which the initiator then
ACC's. If the driver processes the (re)PLOGI ACC prior to the completing
the handling for the earlier ACC it sent the intiators original PLOGI,
there is no state change for completion of the (re)PLOGI. The ndlp remains
in "PLOGI Sent" and the initiator continues sending PRLI's which are
rejected by the target until timeout or retry is reached.
Fix by: When in target mode, defer sending an ACC for the received PLOGI
until unreg RPI completes.
