ccef03c511 USB: sisusbvga: Add endpoint checks
commit df05a9b05e466a46725564528b277d0c570d0104 upstream.

The syzbot fuzzer was able to provoke a WARNING from the sisusbvga driver:

The problem was caused by the fact that the driver does not check
whether the endpoints it uses are actually present and have the
appropriate types.  This can be fixed by adding a simple check of
the endpoints.

b8bbae3236 usb: idmouse: fix an uninit-value in idmouse_open
[ Upstream commit bce2b0539933e485d22d6f6f076c0fcd6f185c4c ]

In idmouse_create_image, if any ftip_command fails, it will
go to the reset label. However, this leads to the data in
bulk_in_buffer[HEADER..IMGSIZE] uninitialized. And the check
for valid image incurs an uninitialized dereference.

Fix this by moving the check before reset label since this
check only be valid if the data after bulk_in_buffer[HEADER]
has concrete data.

Note that this is found by KMSAN, so only kernel compilation
is tested.

commit 0a96fa640dc928da9eaa46a22c46521b037b78ad upstream.

usb_put_dev shouldn't be called when uss720_probe succeeds because of
priv->usbdev. At the same time, priv->usbdev shouldn't be set to NULL
before destroy_priv in uss720_disconnect because usb_put_dev is in
destroy_priv.

Fix this by moving priv->usbdev = NULL after usb_put_dev.

commit 79a4479a17b83310deb0b1a2a274fe5be12d2318 upstream.

USB control-message timeouts are specified in milliseconds and should
specifically not vary with CONFIG_HZ.

Use the common control-message timeout define for the five-second
timeout and drop the driver-specific one.

The direction of the pipe argument must match the request-type direction
bit or control requests may fail depending on the host-controller-driver
implementation.

Fix the set-speed request which erroneously used USB_DIR_IN and update
the default timeout argument to match (same value).

commit 372c93131998c0622304bed118322d2a04489e63 upstream.

Make sure to always cancel the control URB in write() so that it can be
reused after a timeout or spurious CMD_ACK.

Currently any further write requests after a timeout would fail after
triggering a WARN() in usb_submit_urb() when attempting to submit the
already active URB.

07747a44be USB: sisusbvga: Make console support depend on BROKEN
commit 862ee699fefe1e6d6f2c1518395f0b999b8beb15 upstream.

The console part of sisusbvga is broken vs. printk(). It uses in_atomic()
to detect contexts in which it cannot sleep despite the big fat comment in
preempt.h which says: Do not use in_atomic() in driver code.

in_atomic() does not work on kernels with CONFIG_PREEMPT_COUNT=n which
means that spin/rw_lock held regions are not detected by it.

There is no way to make this work by handing context information through to
the driver and this only can be solved once the core printk infrastructure
supports sleepable console drivers.

Make it depend on BROKEN for now.

pm_runtime_get_sync() will increment pm usage at first and it
will resume the device later. If runtime of the device has
error or device is in inaccessible state(or other error state),
resume operation will fail. If we do not call put operation to
decrease the reference, the result is that this device cannot
enter the idle state and always stay busy or other non-idle
state.

0cb686692f USB: apple-mfi-fastcharge: don't probe unhandled devices
From: Bastien Nocera <hadess@hadess.net>

Contrary to the comment above the id table, we didn't implement a match
function. This meant that every single Apple device that was already
plugged in to the computer would have its device driver reprobed
when the apple-mfi-fastcharge driver was loaded, eg. the SD card reader
could be reprobed when the apple-mfi-fastcharge after pivoting root
during boot up and the module became available.

Make sure that the driver probe isn't being run for unsupported
devices by adding a match function that checks the product ID, in
addition to the id_table checking the vendor ID.

7aea2a7ddc usb/misc: usb4604: Use pm_ptr() macro
Use the newly introduced pm_ptr() macro, and mark the suspend/resume
functions __maybe_unused. These functions can then be moved outside the
CONFIG_PM_SUSPEND block, and the compiler can then process them and
detect build failures independently of the config. If unused, they will
simply be discarded by the compiler.

ffeb1e9e89 USB: Replace HTTP links with HTTPS ones
Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
  If not .svg:
    For each line:
      If doesn't contain `\bxmlns\b`:
        For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
	  If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
            If both the HTTP and HTTPS versions
            return 200 OK and serve the same content:
              Replace HTTP with HTTPS.

313da01ad5 usb: misc: sisusbvga: Move static const tables out to different include file
sisusb_init.h is included by multiple source files, but the big data
tables contained are only referenced by one of them, leaving the tables
'defined but not used' by the remainder.  We have a choice to either
place them inside the source file, taking up may lines and potentially
overwhelming the source file OR tuck them away neatly inside their own
headerfile.  The latter was chosen.

Fixes the following W=1 kernel build warning(s):

2b53a19284 USB: sisusbvga: Fix a potential UB casued by left shifting a negative value
The char buffer buf, receives data directly from user space,
so its content might be negative and its elements are left
shifted to form an unsigned integer.

Since left shifting a negative value is undefined behavior, thus
change the char to u8 to elimintate this UB.

Introduce names (en enum) for 0, 1, and 2 constants. We now have
VCI_HALF_BRIGHT, VCI_NORMAL, and VCI_BOLD instead.

Apart from the cleanup,
1) the enum allows for better type checking, and
2) this saves some code. No more fiddling with bits is needed in
   assembly now. (OTOH, the structure is larger.)

For some reason, the TEST_ defines in the usb/ch9.h files did not have
the USB_ prefix on it, making it a bit confusing when reading the file,
as well as not the nicest thing to do in a uapi file.

So fix that up and add the USB_ prefix on to them, and fix up all
in-kernel usages.  This included deleting the duplicate copy in the
net2272.h file.

a7f7f6248d treewide: replace '---help---' in Kconfig files with 'help'
Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), the number of '---help---' has been gradually
decreasing, but there are still more than 2400 instances.

This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.

There are a variety of indentation styles found.

  a) 4 spaces + '---help---'
  b) 7 spaces + '---help---'
  c) 8 spaces + '---help---'
  d) 1 space + 1 tab + '---help---'
  e) 1 tab + '---help---'    (correct indentation)
  f) 1 tab + 1 space + '---help---'
  g) 1 tab + 2 spaces + '---help---'

In order to convert all of them to 1 tab + 'help', I ran the
following commend:

  $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'
