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.

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.

Dynamic FW logging had logic that prematurely breaks from the buffer
filling loop.
Fix the check for buffer overrun by looking before copying and restricting
copy length to the remaining buffer. When copying, ensure space for NULL
character is left in the buffer. While in the routine - ensure the buffer
is cleared before adding elements.

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.

This patch reworks the fdmi symbolic node name data for the following two
issues:
- Correcting extraneous periods following the DV and HN fdmi data fields.
- Avoiding buffer overflow issues when formatting the data.
The fix to the fist issue is to just remove the characters.
The fix to the second issue has all data being staged in temporary storage
before being moved to the real buffer.

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.

In nvme-fc: it's possible to have connected active controllers
and as no references are taken on the LLDD, the LLDD can be
unloaded. The controller would enter a reconnect state and as
long as the LLDD resumed within the reconnect timeout, the
controller would resume. But if a namespace on the controller
is the root device, allowing the driver to unload can be problematic.
To reload the driver, it may require new io to the boot device,
and as it's no longer connected we get into a catch-22 that
eventually fails, and the system locks up.
Fix this issue by taking a module reference for every connected
controller (which is what the core layer did to the transport
module). Reference is cleared when the controller is removed.

Currently the lpfc driver sizes its cpu_map array based on
num_possible_cpus(). However, that can be a value that is less than the
highest cpu id bit that is set. As such, if a thread runs on a cpu with a
larger cpu id, or for_each_possible_cpu() is used, the driver could index
off the end of the array and return garbage or GPF.
The driver maintains its own internal copy of the "num_possible" cpu value
and sizes arrays by it.
Fix by setting the driver's value to the value of the last cpu id bit set
in the possible_mask - plus 1. Thus cpu_map will be sized to allow access
by any cpu id possible.

The current driver attempts to allocate an interrupt vector per cpu using
the systems managed IRQ allocator (flag PCI_IRQ_AFFINITY). The system IRQ
allocator will either provide the per-cpu vector, or return fewer
vectors. When fewer vectors, they are evenly spread between the numa nodes
on the system. When run on an AMD architecture, if interrupts occur to a
cpu that is not in the same numa node as the adapter generating the
interrupt, there are extreme costs and overheads in performance. Thus, if
1:1 vector allocation is used, or the "balanced" vectors in the other numa
nodes, performance can be hit significantly.
A much more performant model is to allocate interrupts only on the cpus
that are in the numa node where the adapter resides. I/O completion is
still performed by the cpu where the I/O was generated. Unfortunately,
there is no flag to request the managed IRQ subsystem allocate vectors only
for the CPUs in the numa node as the adapter.
On AMD architecture, revert the irq allocation to the normal style
(non-managed) and then use irq_set_affinity_hint() to set the cpu
affinity and disable user-space rebalancing.
Tie the support into CPU offline/online. If the cpu being offlined owns a
vector, the vector is re-affinitized to one of the other CPUs on the same
numa node. If there are no more CPUs on the numa node, the vector has all
affinity removed and lets the system determine where it's serviced.
Similarly, when the cpu that owned a vector comes online, the vector is
reaffinitized to the cpu.

The recent affinitization didn't address cpu offlining/onlining. If an
interrupt vector is shared and the low order cpu owning the vector is
offlined, as interrupts are managed, the vector is taken offline. This
causes the other CPUs sharing the vector will hang as they can't get io
completions.
Correct by registering callbacks with the system for Offline/Online
events. When a cpu is taken offline, its eq, which is tied to an interrupt
vector is found. If the cpu is the "owner" of the vector and if the
eq/vector is shared by other CPUs, the eq is placed into a polled mode.
Additionally, code paths that perform io submission on the "sharing CPUs"
will check the eq state and poll for completion after submission of new io
to a wq that uses the eq.
Similarly, when a cpu comes back online and owns an offlined vector, the eq
is taken out of polled mode and rearmed to start driving interrupts for eq.

The driver today is reading service parameters from the firmware and then
overwriting the firmware-provided values with values of its own. There are
some switch features that require preliminary FLOGI's that are
switch-specific and done prior to the actual fabric FLOGI for traffic. The
fw will perform those FLOGIs and will revise the service parameters for the
features configured. As the driver later overwrites those values with its
own values, it misconfigures things like BBSCN use by doing so.
Correct by eliminating the driver-overwrite of firmware values. The driver
correctly re-reads the service parameters after each link up to obtain the
latest values from firmware.

If the driver receives a login that is later then LOGO'd by the remote port
(aka ndlp), the driver, upon the completion of the LOGO ACC transmission,
will logout the node and unregister the rpi that is being used for the
node. As part of the unreg, the node's rpi value is replaced by the
LPFC_RPI_ALLOC_ERROR value. If the port is subsequently offlined, the
offline walks the nodes and ensures they are logged out, which possibly
entails unreg'ing their rpi values. This path does not validate the node's
rpi value, thus doesn't detect that it has been unreg'd already. The
replaced rpi value is then used when accessing the rpi bitmask array which
tracks active rpi values. As the LPFC_RPI_ALLOC_ERROR value is not a valid
index for the bitmask, it may fault the system.
Revise the rpi release code to detect when the rpi value is the replaced
RPI_ALLOC_ERROR value and ignore further release steps.
