Subject: [PATCH 001/149] scsi: esp_scsi: Correct ordering of PCSCSI definition
in esp_rev enum
The order of the definitions in the esp_rev enum is important. The values
are used in comparisons for chip features.
Add a comment to the enum explaining this.
Also, the actual values for the enum fields are irrelevant, so remove the
explicit values (suggested by Geert Uytterhoeven). This makes adding a new
field in the middle of the enum easier.
Finally, move the PCSCSI definition to the right place in the enum. In its
previous location, at the end of the enum, the wrong values are written to
the CONFIG3 register when used with FAST-SCSI targets.

Subject: [PATCH 002/149] scsi: esp_scsi: Add support for FSC chip
The FSC (NCR53CF9x-2 / SYM53CF9x-2) has a different family code than QLogic
or Emulex parts. This caused it to be detected as a FAS100A.
Unforunately, this meant the configuration of the CONFIG3 register was
incorrect. This causes data transfer issues with FAST-SCSI targets.
The FSC also has the CONFIG4 register. It can be used to enable a feature
called Active Negation which should always be enabled according to the data
manual.

Subject: [PATCH 003/149] scsi: ufs: Avoid busy-waiting by eliminating tag
conflicts
Instead of tracking which tags are in use in the ufs_hba.lrb_in_use
bitmask, rely on the block layer tag allocation mechanism. This patch
removes the following busy-waiting loop if ufshcd_issue_devman_upiu_cmd()
and the block layer accidentally allocate the same tag for a SCSI request:
* ufshcd_queuecommand() returns SCSI_MLQUEUE_HOST_BUSY.
* The SCSI core requeues the SCSI command.

completion pointer in request.end_io_data instead of using a waitqueue to
report TMF completion.

Subject: [PATCH 008/149] scsi: ufs: Complete pending requests in host reset
and restore path
In UFS host reset and restore path, before probe, we stop and start the
host controller once. After host controller is stopped, the pending
requests, if any, are cleared from the doorbell, but no completion IRQ
would be raised due to the hba is stopped. These pending requests shall be
completed along with the first NOP_OUT command (as it is the first command
which can raise a transfer completion IRQ) sent during probe. Since the
OCSs of these pending requests are not SUCCESS (because they are not yet
literally finished), their UPIUs shall be dumped. When there are multiple
pending requests, the UPIU dump can be overwhelming and may lead to
stability issues because it is in atomic context. Therefore, before probe,
complete these pending requests right after host controller is stopped and
silence the UPIU dump from them.

Subject: [PATCH 010/149] scsi: ufs: Use DBD setting in mode sense
UFS standard requires DBD field to be set to 1 in MODE SENSE(10).
Some card vendors are more strict and check the DBD field, hence respond
with CHECK_CONDITION (Sense key set to ILLEGAL_REQUEST and ASC set to
INVALID FIELD IN CDB). When host sends MODE SENSE for page caching, as a
result of the CHECK_CONDITION response, host assumes that the device
doesn't support the cache feature and doesn't send SYNCHRONIZE_CACHE
commands to flush the device cache. This can result in data corruption in
case of sudden power down when there is data stored in the device cache.
This patch fixes the DBD field setting as required in UFS standard.

Subject: [PATCH 012/149] scsi: ufs: Do not clear the DL layer timers
During power mode change, PACP_PWR_Req frame sends PAPowerModeUserData
parameters (and they are considered valid by device if Flags[4] -
UserDataValid bit is set in the same frame). Currently we don't set these
PAPowerModeUserData parameters and hardware always sets UserDataValid bit
which would clear all the DL layer timeout values of the peer device after
the power mode change.
This change sets the PAPowerModeUserData[0..5] to UniPro specification
recommended default values, in addition we are also setting the relevant
DME_LOCAL_* timer attributes as required by UFS HCI specification.

Subject: [PATCH 018/149] scsi: ufs: disable irq before disabling clocks
During suspend flow, interrupt shall be disabled before disabling clocks to
avoid potential system hang due to accessing host registers after host
clocks are disabled.
For example, if an interrupt comes with IRQF_IRQPOLL flag configured with
the misrouted interrupt recovery feature enabled, ufshcd ISR may be
triggered even if nothing shall be done for UFS. In this case, system hang
may happen if UFS interrupt status register is accessed with host clocks
disabled.

Subject: [PATCH 029/149] scsi: vmw_pvscsi: Fix swiotlb operation
With swiotlb, the first byte of the sense buffer may in some cases be
uninitialized since we use DMA_FROM_DEVICE, and the device incorrectly
doesn't clear it. In those cases, clear it after DMA unmapping.

Subject: [PATCH 030/149] scsi: vmw_pvscsi: Silence dma mapping errors
These errors typically occur with swiotlb when the swiotlb buffer is full.
But they are transient and would typically unnecessarily worry a user.
Instead of errors, print debug messages.

Subject: [PATCH 031/149] scsi: qla2xxx: Remove defer flag to indicate
immeadiate port loss
During cable pull test case, if the port is disconnected for time larger
than devloss timeout, driver does not mark path offline. In such case,
instead of notifying SCSI-ML of loop down, driver goes into endless loop of
device relogin because defer flag is set.
With newer handling of device relogin in driver discovery, defer flag is
now redundant. This patch removes defer flag and cleans up code handling
port lost indication to SCSI-ML.

Subject: [PATCH 032/149] scsi: qla2xxx: Fix fabric scan hang
On timeout, SRB pointer was cleared from outstanding command array and
dropped. It was not allowed to go through the done process and cleanup.
This patch will abort the SRB where FW will return it with an error status
and resume the normal cleanup.

Subject: [PATCH 038/149] scsi: qla2xxx: Fix stuck login session using
prli_pend_timer
Session is stuck if driver sees FW has received a PRLI. Driver allows FW to
finish with processing of PRLI by checking back with FW at a later time to
see if the PRLI has finished. Instead, driver failed to push forward after
re-checking PRLI completion.
Fixes: ce0ba496dccf ("scsi: qla2xxx: Fix stuck login session")

Subject: [PATCH 041/149] scsi: qla2xxx: Fix RIDA Format-2
This patch fixes offset for Format-2 data structure for Report ID
Acquisition. This caused driver to set remote_nport_id to 0x0000 in N2N
configuration. In a scenario where initiator's WWPN is higher than target's
WWPN, driver will assign 0x00 as target nport-id, which results into login
failure.

Subject: [PATCH 045/149] scsi: lpfc: Fix incomplete NVME discovery when target
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.

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.

Subject: [PATCH 047/149] scsi: lpfc: Fix missing check for CSF in Write Object
Mbox Rsp
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.

Subject: [PATCH 048/149] scsi: lpfc: Fix Fabric hostname registration if
system hostname changes
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.

Subject: [PATCH 049/149] scsi: lpfc: Fix ras_log via debugfs
/sys/kernel/debug/lpfc/fn0/ras_log always shows the same ras_log even if
there are link bounce events triggered via issue_lip
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.

The order of the flags/checks for adapters where FC-AL is supported

Subject: [PATCH 052/149] scsi: lpfc: Fix MDS Latency Diagnostics Err-drop
rates
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.

Subject: [PATCH 055/149] scsi: libsas: Tidy SAS address print format
Currently we use a mixture of %016llx, %llx, and %16llx when printing a SAS
address.
Since the most significant nibble of the SAS address is always 5 - as per
standard - this formatting is not so important; but some fake SAS addresses
for SATA devices may not be. And we have mangled/invalid address to
consider also. And it's better to be consistent in the code, so use a fixed
format.
The SAS address is a fixed size at 64b, so we want to 0 byte extend to 16
nibbles, so use %016llx globally.
Also make some prints to be explicitly hex, and tidy some whitespace issue.

Subject: [PATCH 056/149] scsi: qla2xxx: Improve readability of the code that
handles qla_flt_header
Declare qla_hw_data.flt as a qla_flt_header pointer instead of as a void
pointer. Add a zero-length array at the end of struct qla_flt_header to
make it clear that qla_flt_header and qla_flt_region are contiguous. This
patch removes several casts but does not change any functionality.

blk_revalidate_disk_zones() checks for power of 2 zone size, there is no
need to do it in sd_zbc_check_zones(). Remove this check.

Now that the block layer implement zone checks on revalidate,
sd_zbc_check_zones() is reduced getting the zone size and verifying the
device capacity for device with RC_BASIS=0. Be clear about this by renaming
sd_zbc_check_zones() to sd_zbc_check_capacity() and updating the function
description and comments.

Subject: [PATCH 067/149] scsi: ufs: Remove the SCSI timeout handler
The UFS SCSI timeout handler was needed to compensate that
ufshcd_queuecommand() could return SCSI_MLQUEUE_HOST_BUSY for a long
time. Commit a276c19e3e98 ("scsi: ufs: Avoid busy-waiting by eliminating
tag conflicts") fixed this so the timeout handler is no longer necessary.

Subject: [PATCH 072/149] scsi: ufs-mediatek: introduce reference clock control
Introduce reference clock control in MediaTek Chipset in order to disable
it if it is not necessary by UFS device to save system power.
Currently reference clock can be disabled during system suspend, runtime
suspend and clock-gating after link enters hibernate state.

Subject: [PATCH 077/149] scsi: mpt3sas: Add support for NVMe shutdown
Introduce function _scsih_nvme_shutdown() to issue IO Unit Control message
to IOC firmware with operation code 'shutdown'. This causes IOC firmware to
issue NVMe shutdown commands to all NVMe drives attached to it.
NVMe Shutdown:
NVMe devices need to have a specific shutdown sequence performed before
power is removed. For this, the IOC firmware needs to be notified when the
system is being shutdown. So during the system shutdown time, driver issues
an IO Unit Control request with operation code MPI26_CTRL_OP_SHUTDOWN to
inform firmware that a shutdown is initiated.
This shutdown command is issued only if NVMe devices are attached to the
controller.
During each NVMe device addition, driver reads pcie device page2 to get
shutdown latency (e.g. drive's RTD3 Entry Latency) and updates the max
latency value among the added NVMe drives in ioc->max_shutdown_latency.
This is used as the timeout value for IO Unit Control command at the time
of shutdown.
When a NVMe drive is removed and its shutdown latency matches which
ioc->max_shutdown_latency then ioc->max_shutdown_latency is updated to next
max value (by iterating over the list of available devices). If the
shutdown latency is 0, then default timeout is set to six seconds.

Subject: [PATCH 078/149] scsi: mpt3sas: renamed _base_after_reset_handler
function
Renamed _base_after_reset_handler function to
_base_clear_outstanding_commands so that it can be used in multiple
scenarios with suitable name which matches with the operation it does.
Also renamed its child functions. No functional changes.

Subject: [PATCH 079/149] scsi: mpt3sas: Add support IOCs new state named
COREDUMP
New feature is added in HBA firmware where it copies the collected firmware
logs in flash region named 'CoreDump' whenever HBA firmware faults occur.
For copying the logs to CoreDump flash region firmware needs some time and
hence it has introduced a new IOC state named "CoreDump" State.
Whenever driver detects the CoreDump state then it means that some firmware
fault has occurred and firmware is copying the logs to the coredump flash
region. During this time driver should not perform any operation with the
HBA, driver should wait for HBA firmware to move the IOC state from
'CoreDump' state to 'Fault' state once it's done with copying the logs to
coredump region. Once driver detects the Fault state then it will issue the
diag reset/host reset operation to move the IOC state from Fault to
Operational state.
Here the valid IOC state transactions w.r.t to this CoreDump state feature,
Operational -> Fault:
The IOC transitions to the Fault state when an operational error occurs AND
CoreDump is not supported (or disabled) by the firmware(FW).
Operational -> CoreDump:
The IOC transitions to the CoreDump state when an operational error occurs
AND CoreDump is supported & enabled by the FW.
CoreDump -> Fault:
A transition from CoreDump state to Fault state happens when the FW
completes the CoreDump collection.
CoreDump -> Reset:
A transition out of the CoreDump state happens when the host sets the Reset
Adapter bit in the System Diagnostic Register (Hard Reset). This reset
action indicates that CoreDump took longer than the host time out.
Firmware informs the driver about the maximum time that driver has to wait
for firmware to transition the IOC state from 'CoreDump' to 'FAULT' state
through 'CoreDumpTOSec' field of ManufacturingPage11 page. if this
'CoreDumpTOSec' field value is zero then driver will wait for max 15
seconds.
Driver informs the HBA firmware that it supports this new IOC state named
'CoreDump' state by enabling COREDUMP_ENABLE flag in ConfigurationFlags
field of ioc init request message.
Current patch handles the CoreDump state only during HBA initialization and
release scenarios where watchdog thread (which polls the IOC state in every
one second) is disabled. Next subsequent patch handle the CoreDump state
when watchdog thread is enabled.
During HBA initialization or release execution time if driver detects the
CoreDump state then driver will wait for maximum CoreDumpTOSec value
seconds for FW to copy the logs. After that it will issue the diag reset
operation to move the IOC state to Operational state.

Subject: [PATCH 080/149] scsi: mpt3sas: Handle CoreDump state from watchdog
thread
Watchdog thread polls for IOC state every 1 second. If it detects that IOC
state is in CoreDump state then it immediately stops the IOs and also
clears the outstanding commands issued to the HBA firmware and then it will
poll for IOC state to be out of CoreDump state and once it detects that IOC
state is changed from CoreDump state to Fault state (or) CoreDumpTOSec
number of seconds are elapsed then it will issue host reset operation and
moves the IOC state to Operational state and resumes the IOs.
Whenever any TM is received from SML then if driver detects the IOC state
is in CoreDump state then it will wait for CoreDump state to be cleared and
will host reset operation.

Subject: [PATCH 082/149] scsi: mpt3sas: Optimize mpt3sas driver logging
This improves mpt3sas driver default debug information collection and
allows for a higher percentage of issues being able to be resolved with a
first-time data capture. However, this improvement to balance the amount
of debug data captured with the performance of driver.
Enabled below print messages with out affecting the IO performance,
1. When task abort TM is received then print IO commands's timeout value
and how much time this command has been outstanding.
2. Whenever hard reset occurs then print from where this hard reset has
been issued.
3. Failure message should be displayed for failure scenarios without any
logging level.
4. Added a print after driver successfully register or unregistered a
target drive with the SML. This print will be useful for debugging the
issue where the drive addition or deletion is hanging at SML.
5. During driver load time print request, reply, sense and config page
pool's information such as its address, length and size. Also printed
sg_tablesize information.

Remove usage of device_busy counter from driver. Instead of device_busy
counter now driver uses 'nr_active' counter of request_queue to get the
number of inflight request for a LUN.

Subject: [PATCH 086/149] compat: ARM64: always include asm-generic/compat.h
In order to use compat_* type defininitions in device drivers
outside of CONFIG_COMPAT, move the inclusion of asm-generic/compat.h
ahead of the #ifdef.
All other architectures already do this.

Subject: [PATCH 087/149] compat: provide compat_ptr() on all architectures
In order to avoid needless #ifdef CONFIG_COMPAT checks,
move the compat_ptr() definition to linux/compat.h
where it can be seen by any file regardless of the
architecture.
Only s390 needs a special definition, this can use the
self-#define trick we have elsewhere.

Subject: [PATCH 088/149] compat: scsi: sg: fix v3 compat read/write interface
In the v5.4 merge window, a cleanup patch from Al Viro conflicted
with my rework of the compat handling for sg.c read(). Linus Torvalds
did a correct merge but pointed out that the resulting code is still
unsatisfactory.
I later noticed that the sg_new_read() function still gets the compat
mode wrong, when the 'count' argument is large enough to pass a
compat_sg_io_hdr object, but not a nativ sg_io_hdr.
To address both of these, move the definition of compat_sg_io_hdr
into a scsi/sg.h to make it visible to sg.c and rewrite the logic
for reading req_pack_id as well as the size check to a simpler
version that gets the expected results.
Fixes: c35a5cfb4150 ("scsi: sg: sg_read(): simplify reading ->pack_id of userland sg_io_hdr_t")
Fixes: 98aaaec4a150 ("compat_ioctl: reimplement SG_IO handling")

Subject: [PATCH 089/149] compat_ioctl: block: add blkdev_compat_ptr_ioctl
A lot of block drivers need only a trivial .compat_ioctl callback.
Add a helper function that can be set as the callback pointer
to only convert the argument using the compat_ptr() conversion
and otherwise assume all input and output data is compatible,
or handled using in_compat_syscall() checks.
This mirrors the compat_ptr_ioctl() helper function used in
character devices.

These drivers implement the HDIO_GET_IDENTITY and CDROMVOLREAD ioctl
commands, which are compatible between 32-bit and 64-bit user space and
traditionally handled by compat_blkdev_driver_ioctl().
As a prerequisite to removing that function, make both drivers use
blkdev_compat_ptr_ioctl() as their .compat_ioctl callback.

Subject: [PATCH 091/149] compat_ioctl: move CDROM_SEND_PACKET handling into
scsi
There is only one implementation of this ioctl, so move the handling out
of the common block layer code into the place where it's actually needed.
It also gets called indirectly through pktcdvd, which needs to be aware
of this change.
As I noticed, the old implementation of the compat handler failed to
convert the structure on the way out, so the updated fields never got
written back to user space. This is either not important, or it has
never worked and should be fixed now.

Subject: [PATCH 093/149] compat_ioctl: cdrom: handle CDROM_LAST_WRITTEN
This is the only ioctl command that does not have a proper
compat handler. Making the normal implementation do the
right thing is actually very simply, so just do that by
using an in_compat_syscall() check to avoid the special
case in the pkcdvd driver.

Subject: [PATCH 094/149] compat_ioctl: block: handle cdrom compat ioctl in
non-cdrom drivers
Various block drivers implement the CDROMMULTISESSION,
CDROM_GET_CAPABILITY, and CDROMEJECT ioctl commands, relying on the
block layer to handle compat_ioctl mode for them.
Move this into the drivers directly as a preparation for simplifying
the block layer later.
When only integer arguments or no arguments are passed, the
same handler can be used for .ioctl and .compat_ioctl, and
when only pointer arguments are passed, the newly added
blkdev_compat_ptr_ioctl can be used.

Subject: [PATCH 096/149] compat_ioctl: bsg: add handler
bsg_ioctl() calls into scsi_cmd_ioctl() for a couple of generic commands
and relies on fs/compat_ioctl.c to handle it correctly in compat mode.
Adding a private compat_ioctl() handler avoids that round-trip and lets
us get rid of the generic emulation once this is done.
Note that bsg implements an SG_IO command that is different from the
other drivers and does not need emulation.

Subject: [PATCH 097/149] compat_ioctl: ide: floppy: add handler
Rather than relying on fs/compat_ioctl.c, this adds support
for a compat_ioctl() callback in the ide-floppy driver directly,
which lets it translate the scsi commands.

Subject: [PATCH 098/149] compat_ioctl: scsi: move ioctl handling into drivers
Each driver calling scsi_ioctl() gets an equivalent compat_ioctl()
handler that implements the same commands by calling scsi_compat_ioctl().
The scsi_cmd_ioctl() and scsi_cmd_blk_ioctl() functions are compatible
at this point, so any driver that calls those can do so for both native
and compat mode, with the argument passed through compat_ptr().
With this, we can remove the entries from fs/compat_ioctl.c. The new
code is larger, but should be easier to maintain and keep updated with
newly added commands.

Subject: [PATCH 099/149] compat_ioctl: move sys_compat_ioctl() to ioctl.c
The rest of the fs/compat_ioctl.c file is no longer useful now,
so move the actual syscall as planned.

Subject: [PATCH 100/149] compat_ioctl: simplify the implementation
Now that both native and compat ioctl syscalls are
in the same file, a couple of simplifications can
be made, bringing the implementation closer together:
- do_vfs_ioctl(), ioctl_preallocate(), and compat_ioctl_preallocate()
can become static, allowing the compiler to optimize better
- slightly update the coding style for consistency between
the functions.
- rather than listing each command in two switch statements
for the compat case, just call a single function that has
all the common commands.
As a side-effect, FS_IOC_RESVSP/FS_IOC_RESVSP64 are now available
to x86 compat tasks, along with FS_IOC_RESVSP_32/FS_IOC_RESVSP64_32.
This is harmless for i386 emulation, and can be considered a bugfix
for x32 emulation, which never supported these in the past.

Subject: [PATCH 101/149] compat_ioctl: move cdrom commands into cdrom.c
There is no need for the special cases for the cdrom ioctls any more now,
so make sure that each cdrom driver has a .compat_ioctl() callback and
calls cdrom_compat_ioctl() directly there.

Subject: [PATCH 102/149] compat_ioctl: scsi: handle HDIO commands from drivers
The ata_sas_scsi_ioctl() function implements a number of HDIO_* commands
for SCSI devices, it is used by all libata drivers as well as a few
drivers that support SAS attached SATA drives.
The only command that is not safe for compat ioctls here is
HDIO_GET_32BIT. Change the implementation to check for in_compat_syscall()
in order to do both cases correctly, and change all callers to use it
as both native and compat callback pointers, including the indirect
callers through sas_ioctl and ata_scsi_ioctl.

Subject: [PATCH 103/149] compat_ioctl: move HDIO ioctl handling into
drivers/ide
Most of the HDIO ioctls are only used by the obsolete drivers/ide
subsystem, these can be handled by changing ide_cmd_ioctl() to be aware
of compat mode and doing the correct transformations in place and using
it as both native and compat handlers for all drivers.
The SCSI drivers implementing the same commands are already doing
this in the drivers, so the compat_blkdev_driver_ioctl() function
is no longer needed now.
The BLKSECTSET and HDIO_GETGEO_BIG ioctls are not implemented
in any driver any more and no longer need any conversion.

Subject: [PATCH 104/149] compat_ioctl: block: move blkdev_compat_ioctl() into
ioctl.c
Having both in the same file allows a number of simplifications
to the compat path, and makes it more likely that changes to
the native path get applied to the compat version as well.

Subject: [PATCH 105/149] compat_ioctl: block: simplify compat_blkpg_ioctl()
There is no need to go through a compat_alloc_user_space()
copy any more, just wrap the function in a small helper that
works the same way for native and compat mode.

Subject: [PATCH 106/149] compat_ioctl: simplify up block/ioctl.c
Having separate implementations of blkdev_ioctl() often leads to these
getting out of sync, despite the comment at the top.
Since most of the ioctl commands are compatible, and we try very hard
not to add any new incompatible ones, move all the common bits into a
shared function and leave only the ones that are historically different
in separate functions for native/compat mode.
To deal with the compat_ptr() conversion, pass both the integer
argument and the pointer argument into the new blkdev_common_ioctl()
and make sure to always use the correct one of these.
blkdev_ioctl() is now only kept as a separate exported interfact
for drivers/char/raw.c, which lacks a compat_ioctl variant.
We should probably either move raw.c to staging if there are no
more users, or export blkdev_compat_ioctl() as well.

Subject: [PATCH 107/149] Documentation: document ioctl interfaces better
Documentation/process/botching-up-ioctls.rst was orignally written as
a blog post for DRM driver writers, so it it misses some points while
going into a lot of detail on others.
Try to provide a replacement that addresses typical issues across a wider
range of subsystems, and follows the style of the core-api documentation
better.
Many improvements to the document are suggested by Ben Hutchings
<ben.hutchings@codethink.co.uk>, Jonathan Corbet <corbet@lwn.net> and
Geert Uytterhoeven <geert@linux-m68k.org>.

+======================
+ioctl based interfaces
+======================
+
+ioctl() is the most common way for applications to interface
+with device drivers. It is flexible and easily extended by adding new
+commands and can be passed through character devices, block devices as
+well as sockets and other special file descriptors.
+
+However, it is also very easy to get ioctl command definitions wrong,
+and hard to fix them later without breaking existing applications,
+so this documentation tries to help developers get it right.
+
+Command number definitions
+==========================
+
+The command number, or request number, is the second argument passed to
+the ioctl system call. While this can be any 32-bit number that uniquely
+identifies an action for a particular driver, there are a number of
+conventions around defining them.
+
+``include/uapi/asm-generic/ioctl.h`` provides four macros for defining
+ioctl commands that follow modern conventions: ``_IO``, ``_IOR``,
+``_IOW``, and ``_IOWR``. These should be used for all new commands,
+with the correct parameters:
+
+_IO/_IOR/_IOW/_IOWR
+ The macro name specifies how the argument will be used. It may be a
+ pointer to data to be passed into the kernel (_IOW), out of the kernel
+ (_IOR), or both (_IOWR). _IO can indicate either commands with no
+ argument or those passing an integer value instead of a pointer.
+ It is recommended to only use _IO for commands without arguments,
+ and use pointers for passing data.
+
+type
+ An 8-bit number, often a character literal, specific to a subsystem
+ or driver, and listed in :doc:`../userspace-api/ioctl/ioctl-number`
+
+nr
+ An 8-bit number identifying the specific command, unique for a give
+ value of 'type'
+
+data_type
+ The name of the data type pointed to by the argument, the command number
+ encodes the ``sizeof(data_type)`` value in a 13-bit or 14-bit integer,
+ leading to a limit of 8191 bytes for the maximum size of the argument.
+ Note: do not pass sizeof(data_type) type into _IOR/_IOW/IOWR, as that
+ will lead to encoding sizeof(sizeof(data_type)), i.e. sizeof(size_t).
+ _IO does not have a data_type parameter.
+
+
+Interface versions
+==================
+
+Some subsystems use version numbers in data structures to overload
+commands with different interpretations of the argument.
+
+This is generally a bad idea, since changes to existing commands tend
+to break existing applications.
+
+A better approach is to add a new ioctl command with a new number. The
+old command still needs to be implemented in the kernel for compatibility,
+but this can be a wrapper around the new implementation.
+
+Return code
+===========
+
+ioctl commands can return negative error codes as documented in errno(3);
+these get turned into errno values in user space. On success, the return
+code should be zero. It is also possible but not recommended to return
+a positive 'long' value.
+
+When the ioctl callback is called with an unknown command number, the
+handler returns either -ENOTTY or -ENOIOCTLCMD, which also results in
+-ENOTTY being returned from the system call. Some subsystems return
+-ENOSYS or -EINVAL here for historic reasons, but this is wrong.
+
+Prior to Linux 5.5, compat_ioctl handlers were required to return
+-ENOIOCTLCMD in order to use the fallback conversion into native
+commands. As all subsystems are now responsible for handling compat
+mode themselves, this is no longer needed, but it may be important to
+consider when backporting bug fixes to older kernels.
+
+Timestamps
+==========
+
+Traditionally, timestamps and timeout values are passed as ``struct
+timespec`` or ``struct timeval``, but these are problematic because of
+incompatible definitions of these structures in user space after the
+move to 64-bit time_t.
+
+The ``struct __kernel_timespec`` type can be used instead to be embedded
+in other data structures when separate second/nanosecond values are
+desired, or passed to user space directly. This is still not ideal though,
+as the structure matches neither the kernel's timespec64 nor the user
+space timespec exactly. The get_timespec64() and put_timespec64() helper
+functions can be used to ensure that the layout remains compatible with
+user space and the padding is treated correctly.
+
+As it is cheap to convert seconds to nanoseconds, but the opposite
+requires an expensive 64-bit division, a simple __u64 nanosecond value
+can be simpler and more efficient.
+
+Timeout values and timestamps should ideally use CLOCK_MONOTONIC time,
+as returned by ktime_get_ns() or ktime_get_ts64(). Unlike
+CLOCK_REALTIME, this makes the timestamps immune from jumping backwards
+or forwards due to leap second adjustments and clock_settime() calls.
+
+ktime_get_real_ns() can be used for CLOCK_REALTIME timestamps that
+need to be persistent across a reboot or between multiple machines.
+
+32-bit compat mode
+==================
+
+In order to support 32-bit user space running on a 64-bit machine, each
+subsystem or driver that implements an ioctl callback handler must also
+implement the corresponding compat_ioctl handler.
+
+As long as all the rules for data structures are followed, this is as
+easy as setting the .compat_ioctl pointer to a helper function such as
+compat_ptr_ioctl() or blkdev_compat_ptr_ioctl().
+
+compat_ptr()
+------------
+
+On the s390 architecture, 31-bit user space has ambiguous representations
+for data pointers, with the upper bit being ignored. When running such
+a process in compat mode, the compat_ptr() helper must be used to
+clear the upper bit of a compat_uptr_t and turn it into a valid 64-bit
+pointer. On other architectures, this macro only performs a cast to a
+``void __user *`` pointer.
+
+In an compat_ioctl() callback, the last argument is an unsigned long,
+which can be interpreted as either a pointer or a scalar depending on
+the command. If it is a scalar, then compat_ptr() must not be used, to
+ensure that the 64-bit kernel behaves the same way as a 32-bit kernel
+for arguments with the upper bit set.
+
+The compat_ptr_ioctl() helper can be used in place of a custom
+compat_ioctl file operation for drivers that only take arguments that
+are pointers to compatible data structures.
+
+Structure layout
+----------------
+
+Compatible data structures have the same layout on all architectures,
+avoiding all problematic members:
+
+* ``long`` and ``unsigned long`` are the size of a register, so
+ they can be either 32-bit or 64-bit wide and cannot be used in portable
+ data structures. Fixed-length replacements are ``__s32``, ``__u32``,
+ ``__s64`` and ``__u64``.
+
+* Pointers have the same problem, in addition to requiring the
+ use of compat_ptr(). The best workaround is to use ``__u64``
+ in place of pointers, which requires a cast to ``uintptr_t`` in user
+ space, and the use of u64_to_user_ptr() in the kernel to convert
+ it back into a user pointer.
+
+* On the x86-32 (i386) architecture, the alignment of 64-bit variables
+ is only 32-bit, but they are naturally aligned on most other
+ architectures including x86-64. This means a structure like::
+
+ struct foo {
+ __u32 a;
+ __u64 b;
+ __u32 c;
+ };
+
+ has four bytes of padding between a and b on x86-64, plus another four
+ bytes of padding at the end, but no padding on i386, and it needs a
+ compat_ioctl conversion handler to translate between the two formats.
+
+ To avoid this problem, all structures should have their members
+ naturally aligned, or explicit reserved fields added in place of the
+ implicit padding. The ``pahole`` tool can be used for checking the
+ alignment.
+
+* On ARM OABI user space, structures are padded to multiples of 32-bit,
+ making some structs incompatible with modern EABI kernels if they
+ do not end on a 32-bit boundary.
+
+* On the m68k architecture, struct members are not guaranteed to have an
+ alignment greater than 16-bit, which is a problem when relying on
+ implicit padding.
+
+* Bitfields and enums generally work as one would expect them to,
+ but some properties of them are implementation-defined, so it is better
+ to avoid them completely in ioctl interfaces.
+
+* ``char`` members can be either signed or unsigned, depending on
+ the architecture, so the __u8 and __s8 types should be used for 8-bit
+ integer values, though char arrays are clearer for fixed-length strings.
+
+Information leaks
+=================
+
+Uninitialized data must not be copied back to user space, as this can
+cause an information leak, which can be used to defeat kernel address
+space layout randomization (KASLR), helping in an attack.
+
+For this reason (and for compat support) it is best to avoid any
+implicit padding in data structures. Where there is implicit padding
+in an existing structure, kernel drivers must be careful to fully
+initialize an instance of the structure before copying it to user
+space. This is usually done by calling memset() before assigning to
+individual members.
+
+Subsystem abstractions
+======================
+
+While some device drivers implement their own ioctl function, most
+subsystems implement the same command for multiple drivers. Ideally the
+subsystem has an .ioctl() handler that copies the arguments from and
+to user space, passing them into subsystem specific callback functions
+through normal kernel pointers.
+
+This helps in various ways:
+
+* Applications written for one driver are more likely to work for
+ another one in the same subsystem if there are no subtle differences
+ in the user space ABI.
+
+* The complexity of user space access and data structure layout is done
+ in one place, reducing the potential for implementation bugs.
+
+* It is more likely to be reviewed by experienced developers
+ that can spot problems in the interface when the ioctl is shared
+ between multiple drivers than when it is only used in a single driver.
+
+Alternatives to ioctl
+=====================
+
+There are many cases in which ioctl is not the best solution for a
+problem. Alternatives include:
+
+* System calls are a better choice for a system-wide feature that
+ is not tied to a physical device or constrained by the file system
+ permissions of a character device node
+
+* netlink is the preferred way of configuring any network related
+ objects through sockets.
+
+* debugfs is used for ad-hoc interfaces for debugging functionality
+ that does not need to be exposed as a stable interface to applications.
+
+* sysfs is a good way to expose the state of an in-kernel object
+ that is not tied to a file descriptor.
+
+* configfs can be used for more complex configuration than sysfs
+
+* A custom file system can provide extra flexibility with a simple
+ user interface but adds a lot of complexity to the implementation.

Subject: [PATCH 109/149] scsi: ufs: fix empty check of error history
Currently checking if an error history element is empty or not is by its
"value". In most cases, value is error code.
However this checking is not correct because some errors or events do not
specify any values in error history so values remain as 0, and this will
lead to incorrect empty checking.
Fix it by checking "timestamp" instead of "value" because timestamp will be
always assigned for all history elements

From c40ad6b7fcd35bc4d36db820c7737e1aa18d5d41 Mon Sep 17 00:00:00 2001
From: Stanley Chu <stanley.chu@mediatek.com>
Date: Sat, 11 Jan 2020 15:11:46 +0800
Subject: [PATCH 113/149] scsi: ufs: pass device information to
apply_dev_quirks
Pass UFS device information to vendor-specific variant callback
"apply_dev_quirks" because some platform vendors need to know such
information to apply special handling or quirks in specific devices.
At the same time, modify existing vendor implementations according to the
new interface for those vendor drivers which will be built-in or built as a
module alone with UFS core driver.

Subject: [PATCH 115/149] scsi: iscsi: Don't destroy session if there are
outstanding connections
A faulty userspace that calls destroy_session() before destroying the
connections can trigger the failure. This patch prevents the issue by
refusing to destroy the session if there are outstanding connections.

Subject: [PATCH 116/149] scsi: drivers: base: Support atomic version of
attribute_container_device_trigger
attribute_container_device_trigger invokes callbacks that may fail for one
or more classdevs, for instance, the transport_add_class_device callback,
called during transport creation, does memory allocation. This
information, though, is not propagated to upper layers, and any driver
using the attribute_container_device_trigger API will not know whether any,
some, or all callbacks succeeded.
This patch implements a safe version of this dispatcher, to either succeed
all the callbacks or revert to the original state.

Subject: [PATCH 118/149] scsi: iscsi: Fail session and connection on transport
registration failure
If the transport cannot be registered, the session/connection creation
needs to be failed early to let the initiator know. Otherwise, the system
will have an outstanding connection that cannot be used nor removed by
open-iscsi. The result is similar to the error below, triggered by
injecting a failure in the transport's registration path.
openiscsi reports success:
root@debian-vm:~# iscsiadm -m node -T iqn:lun1 -p 127.0.0.1 -l
Logging in to [iface: default, target: iqn:lun1, portal: 127.0.0.1,3260]
Login to [iface: default, target: iqn:lun1, portal:127.0.0.1,3260] successful.
But cannot remove the session afterwards, since the kernel is in an
inconsistent state.
root@debian-vm:~# iscsiadm -m node -T iqn:lun1 -p 127.0.0.1 -u
iscsiadm: No matching sessions found

Ideally, optimal queue depth will be provided by firmware. The driver

not supported. The driver defined values provide optimal queue depth for
most of the drives and the workloads, as is learned from the firmware
assisted QD results.

Subject: [PATCH 127/149] scsi: megaraid_sas: Do not initiate OCR if controller
is not in ready state
Driver initiates OCR if a DCMD command times out. But there is a deadlock
if the driver attempts to invoke another OCR before the mutex lock
(reset_mutex) is released from the previous session of OCR.
This patch takes care of the above scenario using new flag
MEGASAS_FUSION_OCR_NOT_POSSIBLE to indicate if OCR is possible.

Subject: [PATCH 128/149] scsi: megaraid_sas: Limit the number of retries for
the IOCTLs causing firmware fault
IOCTLs causing firmware fault may end up in failed controller resets and
finally killing the adapter.
This patch fixes this problem as stated below:
In OCR sequence, driver will attempt refiring pended IOCTLs upto two times.
If first two attempts fail, then in third attempt driver will return pended
IOCTLs with EBUSY status to application. These changes are done to ensure
if any of pended IOCTLs is causing firmware fault and resulting into OCR
failure, then in last attempt of OCR driver will refrain firing it to
firmware and saving adapter from being killed due to faulty IOCTL.

A non-zero error value likely being returned by ufshcd_scsi_add_wlus() in
case of failure of adding the WLs, but ufshcd_probe_hba() doesn't use this
value, and doesn't report this failure to upper caller. This patch is to
fix this issue.

Subject: [PATCH 138/149] scsi: ufs: Split ufshcd_probe_hba() based on its
called flow
This patch has two major non-functionality changes:
1. Take scanning host if-statement out from ufshcd_probe_hba(), and move
into a new added function ufshcd_add_lus(). In this new function
ufshcd_add_lus(), the main functionalitis include: ICC initialization, add
well-known LUs, devfreq initialization, UFS bsg probe and scsi host
scan. The reason for this change is that these functionalities only being
called during booting stage flow ufshcd_init()->ufshcd_async_scan(). In the
processes of error handling and power management ufshcd_suspend(),
ufshcd_resume(), ufshcd_probe_hba() being called, but these functionalitis
above metioned are not hit.
2. Move context of initialization of parameters associated with the UFS
device to a new added function ufshcd_device_params_init(). The reason of
this change is that all of these parameters are used by driver, but only
need to be initialized once when booting. Combine them into an integral
function, make them easier maintain.

Subject: [PATCH 142/149] scsi: ufs: Add max_lu_supported in struct
ufs_dev_info
Add one new parameter max_lu_supported in struct ufs_dev_info, which will
be used to express exactly how many general LUs being supported by UFS
device, and initialize it during booting stage. This patch also adds a new
function ufshcd_device_geo_params_init() for initialization of UFS device
geometry descriptor related parameters.

Subject: [PATCH 143/149] scsi: ufs: Use UFS device indicated maximum LU number
According to Jedec standard UFS 3.0 and UFS 2.1 Spec, Maximum number of
logical units supported by the UFS device is indicated by parameter
bMaxNumberLU in Geometry Descriptor. This patch is to delete current hard
code macro definition of UFS_UPIU_MAX_GENERAL_LUN, and switch to use device
indicated number instead.

Subject: [PATCH 144/149] scsi: hisi_sas: use threaded irq to process CQ
interrupts
Currently IRQ_EFFECTIVE_AFF_MASK is enabled for ARM_GIC and ARM_GIC3, so it
only allows a single target CPU in the affinity mask to process interrupts
and also interrupt thread, and the performance of using threaded irq is
almost the same as tasklet. But if the config is not enabled, the interrupt
thread will be allowed all the CPUs in the affinity mask. At that situation
it improves the performance (about 20%).
Note: IRQ_EFFECTIVE_AFF_MASK is configured differently for different
architecture chip, and it seems to be better to make it be configured
easily.

Subject: [PATCH 145/149] scsi: hisi_sas: replace
spin_lock_irqsave/spin_unlock_restore with spin_lock/spin_unlock
After changing tasklet to workqueue or threaded irq, some critical
resources are only used on threads (not in interrupt or bottom half of
interrupt), so replace spin_lock_irqsave/spin_unlock_restore with
spin_lock/spin_unlock to protect those critical resources.
