commit 459b1e8c8fe97fcba0bd1b623471713dce2c5eaf upstream.
The analog input subdevice supports Comedi asynchronous commands that
use Comedi's 16-bit sample format. However, the call to
`comedi_buf_write_samples()` is passing the address of a 32-bit integer
variable. On bigendian machines, this will copy 2 bytes from the wrong
end of the 32-bit value. Fix it by changing the type of the variable
holding the sample value to `unsigned short`.

commit ac0bbf55ed3be75fde1f8907e91ecd2fd589bde3 upstream.
The digital input subdevice supports Comedi asynchronous commands that
read interrupt status information. This uses 16-bit Comedi samples (of
which only the bottom 8 bits contain status information). However, the
interrupt handler is calling `comedi_buf_write_samples()` with the
address of a 32-bit variable `unsigned int status`. On a bigendian
machine, this will copy 2 bytes from the wrong end of the variable. Fix
it by changing the type of the variable to `unsigned short`.

FIFO is triggered 4 intervals after receiving a byte, it's good
when we don't care about the time of reception, but are only
interested in the presence of any activity on the line.
Unfortunately, this method is not suitable for all tasks,
for example, the RS-485 protocol will not work properly,
since the state machine must track the request-response time
and after the timeout expires, a decision is made that the device
on the line is not responding.

commit 46613c9dfa964c0c60b5385dbdf5aaa18be52a9c upstream.
usbip_sockfd_store() is invoked when user requests attach (import)
detach (unimport) usb gadget device from usbip host. vhci_hcd sends
import request and usbip_sockfd_store() exports the device if it is
free for export.
Export and unexport are governed by local state and shared state
- Shared state (usbip device status, sockfd) - sockfd and Device
status are used to determine if stub should be brought up or shut
down. Device status is shared between host and client.
- Local state (tcp_socket, rx and tx thread task_struct ptrs)
A valid tcp_socket controls rx and tx thread operations while the
device is in exported state.
- While the device is exported, device status is marked used and socket,
sockfd, and thread pointers are valid.
Export sequence (stub-up) includes validating the socket and creating
receive (rx) and transmit (tx) threads to talk to the client to provide
access to the exported device. rx and tx threads depends on local and
shared state to be correct and in sync.
Unexport (stub-down) sequence shuts the socket down and stops the rx and
tx threads. Stub-down sequence relies on local and shared states to be
in sync.
There are races in updating the local and shared status in the current
stub-up sequence resulting in crashes. These stem from starting rx and
tx threads before local and global state is updated correctly to be in
sync.
1. Doesn't handle kthread_create() error and saves invalid ptr in local
state that drives rx and tx threads.
2. Updates tcp_socket and sockfd, starts stub_rx and stub_tx threads
before updating usbip_device status to SDEV_ST_USED. This opens up a
race condition between the threads and usbip_sockfd_store() stub up
and down handling.
Fix the above problems:
- Stop using kthread_get_run() macro to create/start threads.
- Create threads and get task struct reference.
- Add kthread_create() failure handling and bail out.
- Hold usbip_device lock to update local and shared states after
creating rx and tx threads.
- Update usbip_device status to SDEV_ST_USED.
- Update usbip_device tcp_socket, sockfd, tcp_rx, and tcp_tx
- Start threads after usbip_device (tcp_socket, sockfd, tcp_rx, tcp_tx,
and status) is complete.
Credit goes to syzbot and Tetsuo Handa for finding and root-causing the
kthread_get_run() improper error handling problem and others. This is a
hard problem to find and debug since the races aren't seen in a normal
case. Fuzzing forces the race window to be small enough for the
kthread_get_run() error path bug and starting threads before updating the
local and shared state bug in the stub-up sequence.

If port terminations are detected in suspend, but link never reaches U0
then xHCI may have an internal uncleared wake state that will cause an
immediate wake after suspend.
This wake state is normally cleared when driver clears the PORT_CSC bit,
which is set after a device is enabled and in U0.
Write 1 to clear PORT_CSC for ports that don't have anything connected
when suspending. This makes sure any pending internal wake states in
xHCI are cleared.

commit 253f588c70f66184b1f3a9bbb428b49bbda73e80 upstream.
A xHC USB 3 port might miss the first wake signal from a USB 3 device
if the port LFPS reveiver isn't enabled fast enough after xHC resume.
xHC host will anyway be resumed by a PME# signal, but will go back to
suspend if no port activity is seen.
The device resends the U3 LFPS wake signal after a 100ms delay, but
by then host is already suspended, starting all over from the
beginning of this issue.
USB 3 specs say U3 wake LFPS signal is sent for max 10ms, then device
needs to delay 100ms before resending the wake.
Don't suspend immediately if port activity isn't detected in resume.
Instead add a retry. If there is no port activity then delay for 120ms,
and re-check for port activity.

commit b1d25e6ee57c2605845595b6c61340d734253eb3 upstream.
According to the datasheet, this controller has a restriction
which "set an endpoint number so that combinations of the DIR bit and
the EPNUM bits do not overlap.". However, since the udc core driver is
possible to assign a bulk pipe as an interrupt endpoint, an endpoint
number may not match the pipe number. After that, when user rebinds
another gadget driver, this driver broke the restriction because
the driver didn't clear any configuration in usb_ep_disable().
Example:
# modprobe g_ncm
Then, EP3 = pipe 3, EP4 = pipe 4, EP5 = pipe 6
# rmmod g_ncm
# modprobe g_hid
Then, EP3 = pipe 6, EP4 = pipe 7.
So, pipe 3 and pipe 6 are set as EP3.
So, clear PIPECFG register in usbhs_pipe_free().

commit 9de2c43acf37a17dc4c69ff78bb099b80fb74325 upstream.
Apparently an application that opens a device and calls select()
on it, will hang if the decice is disconnected. It's a little
surprising that we had this bug for 15 years, but apparently
nobody ever uses select() with a printer: only write() and read(),
and those work fine. Well, you can also select() with a timeout.
The fix is modeled after devio.c. A few other drivers check the
condition first, then do not add the wait queue in case the
device is disconnected. We doubt that's completely race-free.
So, this patch adds the process first, then locks properly
and checks for the disconnect.

As per UAC2 Audio Data Formats spec (2.3.1.1 USB Packets),
if the sampling rate is a constant, the allowable variation
of number of audio slots per virtual frame is +/- 1 audio slot.
It means that endpoint should be able to accept/send +1 audio
slot.
Previous endpoint max_packet_size calculation code
was adding sometimes +1 audio slot due to DIV_ROUND_UP
behaviour which was rounding up to closest integer.
However this doesn't work if the numbers are divisible.
It had no any impact with Linux hosts which ignore
this issue, but in case of more strict Windows it
caused rejected enumeration
Thus always add +1 audio slot to endpoint's max packet size

commit 774514bf977377c9137640a0310bd64eed0f7323 upstream.
An issue has been observed on STM32MP157C-EV1 board, with an erase command
with secure erase argument, ending up waiting for ~4 hours before timeout.
The requested busy timeout from the mmc core ends up with 14784000ms (~4
hours), but the supported host->max_busy_timeout is 86767ms, which leads to
that the core switch to use an R1 response in favor of the R1B and polls
for busy with the host->card_busy() ops. In this case the polling doesn't
work as expected, as we never detects that the card stops signaling busy,
which leads to the following message:
mmc1: Card stuck being busy! __mmc_poll_for_busy
The problem boils done to that the stm32 variants can't use R1 responses in
favor of R1B responses, as it leads to an internal state machine in the
controller to get stuck. To continue to process requests, it would need to
be reset.
To fix this problem, let's set MMC_CAP_NEED_RSP_BUSY for the stm32 variant,
which prevent the mmc core from switching to R1 responses. Additionally,
let's cap the cmd->busy_timeout to the host->max_busy_timeout, thus rely on
86767ms to be sufficient (~66 seconds was need for this test case).

When creating a new event channel with 2-level events the affinity
needs to be reset initially in order to avoid using an old affinity
from earlier usage of the event channel port. So when tearing an event
channel down reset all affinity bits.
The same applies to the affinity when onlining a vcpu: all old
affinity settings for this vcpu must be reset. As percpu events get
initialized before the percpu event channel hook is called,
resetting of the affinities happens after offlining a vcpu (this is
working, as initial percpu memory is zeroed out).

Among others this functions removes the int_handler from the cdev.
During shutdown the device cancels all outstanding IO requests and waits

Unfortunately the clear interrupt will never be received when there is no
interrupt handler connected.
Fix by moving the int_handler removal after the call to the state machine
where no request or interrupt is outstanding.

commit d15dfd31384ba3cb93150e5f87661a76fa419f74 upstream.
In a system supporting MTE, the linear map must allow reading/writing
allocation tags by setting the memory type as Normal Tagged. Currently,
this is only handled for memory present at boot. Hotplugged memory uses
Normal non-Tagged memory.
Introduce pgprot_mhp() for hotplugged memory and use it in
add_memory_resource(). The arm64 code maps pgprot_mhp() to
pgprot_tagged().
Note that ZONE_DEVICE memory should not be mapped as Tagged and
therefore setting the memory type in arch_add_memory() is not feasible.
