[ Upstream commit 25708f73ff171bb4171950c9f4be5aa8504b8459 ]
Enable the retain_ff_enable bit of GDSCR only if the GDSC is already ON.
Once the GDSCR moves to HW control, SW no longer can determine the state
of the GDSCR and setting the retain_ff bit could destroy all the register
contents we intended to save.
Therefore, move the retain_ff configuration before switching the GDSC to
HW trigger mode.

Commit 6a130448498c ("spi: lpspi: Fix wrong transmission when don't use

not be disabled in all cases. If CONT is used and the TX transfer is not
yet completed yet, but the interrupt handler is called because there are
characters to be received, TDIE is replaced with FCIE. When the transfer
is finally completed, SR_TDF is set but the interrupt handler isn't
called again.

[ Upstream commit 4a81f78caa53e0633cf311ca1526377d9bff7479 ]
In the do_validate_mem(), the call to add_interval() does not
handle errors. If kmalloc() fails in add_interval(), it could
result in a null pointer being inserted into the linked list,
leading to illegal memory access when sub_interval() is called
next.
This patch adds an error handling for the add_interval(). If
add_interval() returns an error, the function will return early
with the error code.

[ Upstream commit 30a41ed32d3088cd0d682a13d7f30b23baed7e93 ]
With lan88xx based devices the lan78xx driver can get stuck in an
interrupt loop while bringing the device up, flooding the kernel log
with messages like the following:
lan78xx 2-3:1.0 enp1s0u3: kevent 4 may have been dropped
Removing interrupt support from the lan88xx PHY driver forces the
driver to use polling instead, which avoids the problem.
The issue has been observed with Raspberry Pi devices at least since
4.14 (see [1], bug report for their downstream kernel), as well as
with Nvidia devices [2] in 2020, where disabling interrupts was the
vendor-suggested workaround (together with the claim that phylib
changes in 4.9 made the interrupt handling in lan78xx incompatible).
Iperf reports well over 900Mbits/sec per direction with client in
--dualtest mode, so there does not seem to be a significant impact on
throughput (lan88xx device connected via switch to the peer).

[ Upstream commit cf499391982d877e9313d2adeedcf5f1ffe05d6e ]
In preparation of removing the .ack_interrupt() callback, we must replace
its occurrences (aka phy_clear_interrupt), from the 2 places where it is
called from (phy_enable_interrupts and phy_disable_interrupts), with
equivalent functionality.
This means that clearing interrupts now becomes something that the PHY
driver is responsible of doing, before enabling interrupts and after
clearing them. Make this driver follow the new contract.

[ Upstream commit e01a3feb8f69ab620b0016498603cad364f65224 ]
In an attempt to actually support shared IRQs in phylib, we now move the
responsibility of triggering the phylib state machine or just returning
IRQ_NONE, based on the IRQ status register, to the PHY driver. Having
3 different IRQ handling callbacks (.handle_interrupt(),
.did_interrupt() and .ack_interrupt() ) is confusing so let the PHY
driver implement directly an IRQ handler like any other device driver.
Make this driver follow the new convention.

[ Upstream commit 43f0999af011fba646e015f0bb08b6c3002a0170 ]
Currently, when device mtu is updated, vmxnet3 updates netdev mtu, quiesces
the device and then reactivates it for the ESXi to know about the new mtu.
So, technically the OS stack can start using the new mtu before ESXi knows
about the new mtu.
This can lead to issues for TSO packets which use mss as per the new mtu
configured. This patch fixes this issue by moving the mtu write after
device quiesce.

[ Upstream commit 157ae5ffd76a2857ccb4b7ce40bc5a344ca00395 ]
Fix a potential deadlock bug. Observe that in the mtk-cqdma.c
file, functions like mtk_cqdma_issue_pending() and
mtk_cqdma_free_active_desc() properly acquire the pc lock before the vc
lock when handling pc and vc fields. However, mtk_cqdma_tx_status()
violates this order by first acquiring the vc lock before invoking
mtk_cqdma_find_active_desc(), which subsequently takes the pc lock. This
reversed locking sequence (vc → pc) contradicts the established
pc → vc order and creates deadlock risks.
Fix the issue by moving the vc lock acquisition code from
mtk_cqdma_find_active_desc() to mtk_cqdma_tx_status(). Ensure the pc lock
is acquired before the vc lock in the calling function to maintain correct
locking hierarchy. Note that since mtk_cqdma_find_active_desc() is a
static function with only one caller (mtk_cqdma_tx_status()), this
modification safely eliminates the deadlock possibility without affecting
other components.
This possible bug is found by an experimental static analysis tool
developed by our team. This tool analyzes the locking APIs to extract
function pairs that can be concurrently executed, and then analyzes the
instructions in the paired functions to identify possible concurrency bugs
including deadlocks, data races and atomicity violations.

[ Upstream commit 3e38f946062b4845961ab86b726651b4457b2af8 ]
If an input changes state during wake-up and is used as an interrupt
source, the IRQ handler reads the volatile input register to clear the
interrupt mask and deassert the IRQ line. However, the IRQ handler is
triggered before access to the register is granted, causing the read
operation to fail.
As a result, the IRQ handler enters a loop, repeatedly printing the
"failed reading register" message, until `pca953x_resume()` is eventually
called, which restores the driver context and enables access to
registers.
Fix by disabling the IRQ line before entering suspend mode, and
re-enabling it after the driver context is restored in `pca953x_resume()`.
An IRQ can be disabled with disable_irq() and still wake the system as
long as the IRQ has wake enabled, so the wake-up functionality is
preserved.

[ Upstream commit f063a28002e3350088b4577c5640882bf4ea17ea ]
The threaded IRQ function in this driver is reading the flag twice: once to
lock a mutex and once to unlock it. Even though the code setting the flag
is designed to prevent it, there are subtle cases where the flag could be
true at the mutex_lock stage and false at the mutex_unlock stage. This
results in the mutex not being unlocked, resulting in a deadlock.
Fix it by making the opt3001_irq() code generally more robust, reading the
flag into a variable and using the variable value at both stages.

commit 9dba9a45c348e8460da97c450cddf70b2056deb3 upstream.
Fix a use-after-free window by correcting the buffer release sequence in
the deferred receive path. The code freed the RQ buffer first and only
then cleared the context pointer under the lock. Concurrent paths (e.g.,
ABTS and the repost path) also inspect and release the same pointer under
the lock, so the old order could lead to double-free/UAF.
Note that the repost path already uses the correct pattern: detach the
pointer under the lock, then free it after dropping the lock. The
deferred path should do the same.

commit 0e20450829ca3c1dbc2db536391537c57a40fe0b upstream.
The adapter->chan_stats[] array is initialized in
mwifiex_init_channel_scan_gap() with vmalloc(), which doesn't zero out
memory. The array is filled in mwifiex_update_chan_statistics()
and then the user can query the data in mwifiex_cfg80211_dump_survey().
There are two potential issues here. What if the user calls
mwifiex_cfg80211_dump_survey() before the data has been filled in.
Also the mwifiex_update_chan_statistics() function doesn't necessarily
initialize the whole array. Since the array was not initialized at
the start that could result in an information leak.
Also this array is pretty small. It's a maximum of 900 bytes so it's
more appropriate to use kcalloc() instead vmalloc().

[ Upstream commit a556f06338e1d5a85af0e32ecb46e365547f92b9 ]
list_first_entry() never returns NULL - if the list is empty, it still
returns a pointer to an invalid object, leading to potential invalid
memory access when dereferenced.
Fix this by using list_first_entry_or_null instead of list_first_entry.

[ Upstream commit 0704a3da7ce50f972e898bbda88d2692a22922d9 ]
dsp_hwec_enable() allocates dup pointer by kstrdup(arg),
but then it updates dup variable by strsep(&dup, ",").
As a result when it calls kfree(dup), the dup variable may be
a modified pointer that no longer points to the original allocated
memory, causing a memory leak.
The issue is the same pattern as fixed in commit c6a502c22999
("mISDN: Fix memory leak in dsp_pipeline_build()").

[ Upstream commit b79e498080b170fd94fc83bca2471f450811549b ]
The current code incorrectly passes (XIRCREG1_ECR | FullDuplex) as
the register address to GetByte(), instead of fetching the register
value and OR-ing it with FullDuplex. This results in an invalid
register access.
Fix it by reading XIRCREG1_ECR first, then or-ing with FullDuplex
before writing it back.

commit 2682468671aa0b4d52ae09779b48212a80d71b91 upstream.
When a user requests more than 60 bytes of data the MCP2221 must chunk
the data in chunks up to 60 bytes long (see command/response code 0x40
in the datasheet).
In order to signal that the device has more data the (undocumented) byte
at byte index 2 of the Get I2C Data response uses the value 0x54. This
contrasts with the case for the final data chunk where the value
returned is 0x55 (MCP2221_I2C_READ_COMPL). The fact that 0x55 was not
returned in the response was interpreted by the driver as a failure
meaning that all reads of more than 60 bytes would fail.
Add support for reads that are split over multiple chunks by looking for
the response code indicating that more data is expected and continuing
the read as the code intended. Some timing delays are required to ensure
the chip has time to refill its FIFO as data is read in from the I2C
bus. This timing has been tested in my system when configured for bus
speeds of 50KHz, 100KHz, and 400KHz and operates well.

commit 02a46753601a24e1673d9c28173121055e8e6cc9 upstream.
Since the initial commit of this driver the I2C bus speed has been
reconfigured for every single transfer. This is despite the fact that we
never change the speed and it is never "lost" by the chip.
Upon investigation we find that what was really happening was that the
setting of the bus speed had the side effect of cancelling a previous
failed command if there was one, thereby freeing the bus. This is the
part that was actually required to keep the bus operational in the face
of failed commands.
Instead of always setting the speed, we now correctly cancel any failed
commands as they are detected. This means we can just set the bus speed
at probe time and remove the previous speed sets on each transfer.
This has the effect of improving performance and reducing the number of
commands required to complete transfers.

commit d3af6ca9a8c34bbd8cff32b469b84c9021c9e7e4 upstream.
After hid_hw_start() is called hidinput_connect() will eventually be
called to set up the device with the input layer since the
HID_CONNECT_DEFAULT connect mask is used. During hidinput_connect()
all input and output reports are processed and corresponding hid_inputs
are allocated and configured via hidinput_configure_usages(). This
process involves slot tagging report fields and configuring usages
by setting relevant bits in the capability bitmaps. However it is possible
that the capability bitmaps are not set at all leading to the subsequent
hidinput_has_been_populated() check to fail leading to the freeing of the
hid_input and the underlying input device.
This becomes problematic because a malicious HID device like a
ASUS ROG N-Key keyboard can trigger the above scenario via a
specially crafted descriptor which then leads to a user-after-free
when the name of the freed input device is written to later on after
hid_hw_start(). Below, report 93 intentionally utilises the
HID_UP_UNDEFINED Usage Page which is skipped during usage
configuration, leading to the frees.
