Pull removal of most of fs/compat_ioctl.c from Arnd Bergmann:
"As part of the cleanup of some remaining y2038 issues, I came to
fs/compat_ioctl.c, which still has a couple of commands that need
support for time64_t.
In completely unrelated work, I spent time on cleaning up parts of
this file in the past, moving things out into drivers instead.
After Al Viro reviewed an earlier version of this series and did a lot
more of that cleanup, I decided to try to completely eliminate the
rest of it and move it all into drivers.
This series incorporates some of Al's work and many patches of my own,
but in the end stops short of actually removing the last part, which
is the scsi ioctl handlers. I have patches for those as well, but they
need more testing or possibly a rewrite"

The touch timer is set up in intf1. If the second interface does not exist,
the timer and touch input device are not setup and we get the following

The .ioctl and .compat_ioctl file operations have the same prototype so
they can both point to the same function, which works great almost all
the time when all the commands are compatible.
One exception is the s390 architecture, where a compat pointer is only
31 bit wide, and converting it into a 64-bit pointer requires calling
compat_ptr(). Most drivers here will never run in s390, but since we now
have a generic helper for it, it's easy enough to use it consistently.
I double-checked all these drivers to ensure that all ioctl arguments
are used as pointers or are ignored, but are not interpreted as integer
values.

Fix multiple cases of out of bounds (OOB) read associated with
MCE device receive/input data handling.
In reference for the OOB cases below, the incoming/read (byte) data
format when the MCE device responds to a command is:
{ cmd_prefix, subcmd, data0, data1, ... }
where cmd_prefix are:
MCE_CMD_PORT_SYS
MCE_CMD_PORT_IR
and subcmd examples are:
MCE_RSP_GETPORTSTATUS
MCE_RSP_EQIRNUMPORTS
...
Response size dynamically depends on cmd_prefix and subcmd.
So data0, data1, ... may or may not be present on input.
Multiple responses may return in a single receiver buffer.
The trigger condition for OOB read is typically random or
corrupt input data that fills the mceusb receiver buffer.
Case 1:
mceusb_handle_command() reads data0 (var hi) and data1 (var lo)
regardless of whether the response includes such data.
If { cmd_prefix, subcmd } is at the end of the receiver buffer,
read past end of buffer occurs.
This case was reported by
KASAN: slab-out-of-bounds Read in mceusb_dev_recv
https://syzkaller.appspot.com/bug?extid=c7fdb6cb36e65f2fe8c9
Fix: In mceusb_handle_command(), change variable hi and lo to
pointers, and dereference only when required.
Case 2:
If response with data is truncated at end of buffer after
{ cmd_prefix, subcmd }, mceusb_handle_command() reads past
end of buffer for data0, data1, ...
Fix: In mceusb_process_ir_data(), check response size with
remaining buffer size before invoking mceusb_handle_command().
+ if (i + ir->rem < buf_len)
mceusb_handle_command(ir, &ir->buf_in[i - 1]);
Case 3:
mceusb_handle_command() handles invalid/bad response such as
{ 0x??, MCE_RSP_GETPORTSTATUS } of length 2 as a response
{ MCE_CMD_PORT_SYS, MCE_RSP_GETPORTSTATUS, data0, ... }
of length 7. Read OOB occurs for non-existent data0, data1, ...
Cause is mceusb_handle_command() does not check cmd_prefix value.
Fix: mceusb_handle_command() must test both cmd_prefix and subcmd.
Case 4:
mceusb_process_ir_data() receiver parser state SUBCMD is
possible at start (i=0) of receiver buffer resulting in buffer
offset=-1 passed to mceusb_dev_printdata().
Bad offset results in OOB read before start of buffer.
[1214218.580308] mceusb 1-1.3:1.0: rx data[0]: 00 80 (length=2)
[1214218.580323] mceusb 1-1.3:1.0: Unknown command 0x00 0x80
...
[1214218.580406] mceusb 1-1.3:1.0: rx data[14]: 7f 7f (length=2)
[1214218.679311] mceusb 1-1.3:1.0: rx data[-1]: 80 90 (length=2)
[1214218.679325] mceusb 1-1.3:1.0: End of raw IR data
[1214218.679340] mceusb 1-1.3:1.0: rx data[1]: 7f 7f (length=2)
Fix: If parser_state is SUBCMD after processing receiver buffer,
reset parser_state to CMD_HEADER.
In effect, discard cmd_prefix at end of receiver buffer.
In mceusb_dev_printdata(), abort if buffer offset is out of bounds.
Case 5:
If response with data is truncated at end of buffer after
{ cmd_prefix, subcmd }, mceusb_dev_printdata() reads past
end of buffer for data0, data1, ...
while decoding the response to print out.
Fix: In mceusb_dev_printdata(), remove unneeded buffer offset
adjustments (var start and var skip) associated with MCE gen1 header.
Test for truncated MCE cmd response (compare offset+len with buf_len)
and skip decoding of incomplete response.
Move IR data tracing to execute before the truncation test.

Fix and eliminate mceusb's IR length limit for IR signals transmitted to
the MCE IR blaster ports.
An IR signal TX exceeding 306 pulse/space samples presently causes -EINVAL
return error. There's no such limitation nor error with the MCE device
hardware. And valid IR signals exist with more than 400 pulse/space for the
control of certain appliances (eg Panasonic ACXA75C00600 air conditioner).
The scope of this patch is limited to the mceusb driver. There are still
IR signal TX length and time constraints that related modules of rc core
(eg LIRC) impose, further up the driver stack.
Changes for mceusb_tx_ir():
Converts and sends LIRC IR pulse/space sequence to MCE device IR
pulse/space format.
Break long length LIRC sequence into multiple (unlimited number of) parts
for sending to the MCE device.
Reduce kernel stack IR buffer size: 128 (was 384)
Increase MCE IR data packet size: 31 (was 5)
Zero time LIRC pulse/space no longer copied to MCE IR data.
Eliminate overwriting the source/input LIRC IR data in txbuf[].
Eliminate -EINVAL return; return number of IR samples sent (>0) or
MCE write error code (<0).
New mce_write() and mce_write_callback():
Implements synchronous blocking I/O, with timeout, for writing/sending
data to the MCE device.
An unlimited multipart IR signal sent to the MCE device faster than real
time requires flow control absent with the original mce_request_packet()
and mce_async_callback() asynchronous I/O implementation. Also absent is
TX error feedback.
mce_write() combines and replaces mce_request_packet() and
mce_async_callback() with conversion to synchronous I/O.
mce_write() returns bytes sent (>0) or MCE device write error (<0).
Debug hex dump TX data before processing.
Rename mce_async_out() -> mce_command_out():
The original name is misleading with underlying synchronous I/O
implementation. Function renamed to mce_command_out().
Changes in mceusb_handle_command():
Add support for MCE device error case MCE_RSP_TX_TIMEOUT
"IR TX timeout (TX buffer underrun)"
Changes in mceusb_dev_printdata():
Changes support test and debug of multipart TX IR.
Add buffer boundary information (offset and buffer size) to TX hex dump.
Correct TX trace bug "Raw IR data, 0 pulse/space samples"
Add trace for MCE_RSP_TX_TIMEOUT "IR TX timeout (TX buffer underrun)"
Other changes:
The driver's write to USB device architecture change (async to sync I/O)
is significant so we bump DRIVER_VERSION to "1.95" (from "1.94").

This patch schedules a USB reset device call following a USB clear
halt error. The issues solved, and patch implementation,
are similar to those found in
drivers/hid/usbhid/hid-core.c.
As seen on very rare occasions approximately one time per month
(mceusb device 2304:0225 in this sample)
Jul 27 2018 15:09:39
[59388.696941] mceusb 1-1.1.2:1.0: Error: urb status = -32 (RX HALT)
[59388.698838] mceusb 1-1.1.2:1.0: rx clear halt error -32
the device can get into RX or TX HALT state where usb_clear_halt()
also fails and also returns -EPIPE (HALT/STALL). After which, all
further mceusb device control and data I/O always fail with HALT/STALL.
Subsequently, the entire mceusb device no longer functions.
Cause and problem replication conditions remain unknown.
Further troubleshooting reveals usb_reset_device()
restores mceusb device operation.
Patch test 1:
Hot unplugging the mceusb device triggers USB RX HALT and
USB clear halt errors. A mceusb_dev_disconnect() call follows unplug.
This patch's reset device call invokes an extra
mceusb_dev_probe()
mceusb_dev_disconnect()
cycle, before the mceusb driver detaches.
The additional probe/disconnect verifies the patch's device reset
code executed.
But note this patch is for USB clear halt error cases not caused by
unplugging the mceusb device.
Patch test 2:
Simulate a RX HALT and a clear halt error with instrumented code in
the driver.
Jul 12 2019 19:41:18
[522745.263104] mceusb 1-1.3:1.0: set rx halt retval, 0
[522745.263943] mceusb 1-1.3:1.0: Error: rx urb status = -32 (RX HALT)

[522745.272917] mceusb 1-1.3:1.0: stuck RX HALT state requires USB Reset Device to clear

[522745.836832] mceusb 1-1.3:1.0: acceptable bulk outbound endpoint found
...
The result matches what is expected when the device gets into
a real rx clear halt error case by itself.
This is the same sequence of messages when manually invoking
the ./usbreset command line utility with an unpatched mceusb driver.

The IR protocol can now only be set via the rc protocols sysfs file rather
than via module parameters or a custom procfs file. So, it is no longer
necessary to periodically check for protocol changes.
The IR_RCMM protocol does not decode the Philips RC-MM protocol (12, 24 or
32 bit variants) or any protocol rc-core can encode, so this is marked
RC_PROTO_UNKNOWN.
