Since the linked fixes: commit, specifying a CPU on hybrid platforms
results in an error because Perf tries to open an extended type event
on "any" CPU which isn't valid. Extended type events can only be opened
on CPUs that match the type.
Before (working):
$ perf record --cpu 1 -- true
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 2.385 MB perf.data (7 samples) ]
After (not working):
$ perf record -C 1 -- true
WARNING: A requested CPU in '1' is not supported by PMU 'cpu_atom' (CPUs 16-27) for event 'cycles:P'
Error:
The sys_perf_event_open() syscall returned with 22 (Invalid argument) for event (cpu_atom/cycles:P/).
/bin/dmesg | grep -i perf may provide additional information.
(Ignore the warning message, that's expected and not particularly
relevant to this issue).
This is because perf_cpu_map__intersect() of the user specified CPU (1)
and one of the PMU's CPUs (16-27) correctly results in an empty (NULL)
CPU map. However for the purposes of opening an event, libperf converts
empty CPU maps into an any CPU (-1) which the kernel rejects.
Fix it by deleting evsels with empty CPU maps in the specific case where
user requested CPU maps are evaluated.

The refactoring of tool PMU events to have a PMU then adding the expr
literals to the tool PMU made it so that the literal system_tsc_freq
was only supported on x86. Update the test expectations to match -
namely the parsing is x86 specific and only yields a non-zero value on
Intel.

In 'NOFENTRY_ARGS' test case for syntax check, any offset X of
`vfs_read+X` except function entry offset (0) fits the criterion,
even if that offset is not at instruction boundary, as the parser
comes before probing. But with "ENDBR64" instruction on x86, offset
4 is treated as function entry. So, X can't be 4 as well. Thus, 8
was used as offset for the test case. On 64-bit powerpc though, any
offset <= 16 can be considered function entry depending on build
configuration (see arch_kprobe_on_func_entry() for implementation
details). So, use `vfs_read+20` to accommodate that scenario too.

The bt_copy_from_sockptr() return value is being misinterpreted by most
users: a non-zero result is mistakenly assumed to represent an error code,
but actually indicates the number of bytes that could not be copied.
Remove bt_copy_from_sockptr() and adapt callers to use
copy_safe_from_sockptr().
For sco_sock_setsockopt() (case BT_CODEC) use copy_struct_from_sockptr() to
scrub parts of uninitialized buffer.
Opportunistically, rename `len` to `optlen` in hci_sock_setsockopt_old()
and hci_sock_setsockopt().

Syzbot reports [1] an uninitialized value issue found by KMSAN in
dib3000_read_reg().
Local u8 rb[2] is used in i2c_transfer() as a read buffer; in case
that call fails, the buffer may end up with some undefined values.
Since no elaborate error handling is expected in dib3000_write_reg(),
simply zero out rb buffer to mitigate the problem.

Since commit cdd30ebb1b9f ("module: Convert symbol namespace to string
literal"), exported symbols marked by EXPORT_SYMBOL_NS(_GPL) are
ignored by "kernel-doc -export" in fresh build of "make htmldocs".
This is because regex in the perl script for those markers fails to
match the new signatures:
- EXPORT_SYMBOL_NS(symbol, "ns");
- EXPORT_SYMBOL_NS_GPL(symbol, "ns");
Update the regex so that it matches quoted string.
Note: Escape sequence of \w is good for C identifiers, but can be
too strict for quoted strings. Instead, use \S, which matches any
non-whitespace character, for compatibility with possible extension
of namespace convention in the future [1].

One specific test condition: the default registers of p[j].reg ~
p[j+3].reg are 0, TASDEVICE_REG(0x00, 0x14, 0x38)(PLT_FLAG_REG),
TASDEVICE_REG(0x00, 0x14, 0x40)(SINEGAIN_REG), and
TASDEVICE_REG(0x00, 0x14, 0x44)(SINEGAIN2_REG). After first calibration,
they are freshed to TASDEVICE_REG(0x00, 0x1a, 0x20), TASDEVICE_REG(0x00,
0x16, 0x58)(PLT_FLAG_REG), TASDEVICE_REG(0x00, 0x14, 0x44)(SINEGAIN_REG),
and TASDEVICE_REG(0x00, 0x16, 0x64)(SINEGAIN2_REG) via "Calibration Start"
kcontrol. In second calibration, the p[j].reg ~ p[j+3].reg have already
become tas2781_cali_start_reg. However, p[j+2].reg, TASDEVICE_REG(0x00,
0x14, 0x44)(SINEGAIN_REG), will be freshed to TASDEVICE_REG(0x00, 0x16,
0x64), which is the third register in the input params of the kcontrol.
This is why only first calibration can work, the second-time, third-time
or more-time calibration always failed without reboot. Of course, if no
p[j].reg is in the list of tas2781_cali_start_reg, this stress test can
work well.

SoC supports a power-saving mode where power to most of the SoC
components is turned off. Add suspend/resume support to the SSIF-2 driver
to support this power-saving mode.
On SNDRV_PCM_TRIGGER_SUSPEND trigger the SSI is stopped (the stream
user pointer is left untouched to avoid breaking user space and the dma
buffer pointer is set to zero), on SNDRV_PCM_TRIGGER_RESUME software reset
is issued for the SSIF-2 IP and the clocks are re-configured.

The code initially issued software reset on SNDRV_PCM_TRIGGER_START
action only before starting the first stream. This can be easily moved to
hw_params() as the action is similar to setting the clocks. Moreover,
according to the hardware manual (Table 35.7 Bits Initialized by Software
Reset of the SSIFCR.SSIRST Bit) the software reset action acts also on the
clock dividers bits. Due to this issue the software reset in hw_params()
before configuring the clock dividers. This also simplifies the code in
trigger API.

The stop trigger invokes rz_ssi_stop() and rz_ssi_stream_quit().
- The purpose of rz_ssi_stop() is to disable TX/RX, terminate DMA
transactions, and set the controller to idle.
- The purpose of rz_ssi_stream_quit() is to reset the substream-specific
software data by setting strm->running and strm->substream appropriately.
The function rz_ssi_is_stream_running() checks if both strm->substream and
strm->running are valid and returns true if so. Its implementation is as
follows:
static inline bool rz_ssi_is_stream_running(struct rz_ssi_stream *strm)
{
return strm->substream && strm->running;
}
When the controller is configured in full-duplex mode (with both playback
and capture active), the rz_ssi_stop() function does not modify the
controller settings when called for the first substream in the full-duplex
setup. Instead, it simply sets strm->running = 0 and returns if the
companion substream is still running. The following code illustrates this:
static int rz_ssi_stop(struct rz_ssi_priv *ssi, struct rz_ssi_stream *strm)
{
strm->running = 0;
if (rz_ssi_is_stream_running(&ssi->playback) ||
rz_ssi_is_stream_running(&ssi->capture))
return 0;
// ...
}
The controller settings, along with the DMA termination (for the last
stopped substream), are only applied when the last substream in the
full-duplex setup is stopped.
While applying the controller settings only when the last substream stops
is not problematic, terminating the DMA operations for only one substream
causes failures when starting and stopping full-duplex operations multiple
times in a loop.
To address this issue, call dmaengine_terminate_async() for both substreams
involved in the full-duplex setup when the last substream in the setup is
stopped.

Currently the stop routine of rswitch driver does not immediately
prevent hardware from continuing to update descriptors and requesting
interrupts.
It can happen that when rswitch_stop() executes the masking of
interrupts from the queues of the port being closed, napi poll for
that port is already scheduled or running on a different CPU. When
execution of this napi poll completes, it will unmask the interrupts.
And unmasked interrupt can fire after rswitch_stop() returns from
napi_disable() call. Then, the handler won't mask it, because
napi_schedule_prep() will return false, and interrupt storm will
happen.
This can't be fixed by making rswitch_stop() call napi_disable() before
masking interrupts. In this case, the interrupt storm will happen if
interrupt fires between napi_disable() and masking.
Fix this by checking for priv->opened_ports bit when unmasking
interrupts after napi poll. For that to be consistent, move
priv->opened_ports changes into spinlock-protected areas, and reorder
other operations in rswitch_open() and rswitch_stop() accordingly.

The device tree node saved in the rswitch_device structure is used at
several driver locations. So passing this node to of_node_put() after

If error path is taken while filling descriptor for a frame, skb
pointer is left in the entry. Later, on the ring entry reuse, the
same entry could be used as a part of a multi-descriptor frame,
and skb for that new frame could be stored in a different entry.
Then, the stale pointer will reach the completion routine, and passed
to the release operation.
Fix that by clearing the saved skb pointer at the error path.

If hardware is already transmitting, it can start handling the
descriptor being written to immediately after it observes updated DT
field, before the queue is kicked by a write to GWTRC.
If the start_xmit() execution is preempted at unfortunate moment, this
transmission can complete, and interrupt handled, before gq->cur gets
updated. With the current implementation of completion, this will cause
the last entry not completed.
Fix that by changing completion loop to check DT values directly, instead
of depending on gq->cur.

When sending frame split into multiple descriptors, hardware processes
descriptors one by one, including writing back DT values. The first
descriptor could be already marked as completed when processing of
next descriptors for the same frame is still in progress.
Although only the last descriptor is configured to generate interrupt,
completion of the first descriptor could be noticed by the driver when
handling interrupt for the previous frame.
Currently, driver stores skb in the entry that corresponds to the first
descriptor. This results into skb could be unmapped and freed when
hardware did not complete the send yet. This opens a window for
corrupting the data being sent.
Fix this by saving skb in the entry that corresponds to the last
descriptor used to send the frame.

The cifs_io_request struct (a wrapper around netfs_io_request) holds open
the file on the server, even beyond the local Linux file being closed.
This can cause problems with Windows-based filesystems as the file's name
still exists after deletion until the file is closed, preventing the parent
directory from being removed and causing spurious test failures in xfstests
due to inability to remove a directory. The symptom looks something like
this in the test output:
rm: cannot remove '/mnt/scratch/test/p0/d3': Directory not empty
rm: cannot remove '/mnt/scratch/test/p1/dc/dae': Directory not empty
Fix this by waiting in unlink and rename for any outstanding I/O requests
to be completed on the target file before removing that file.
Note that this doesn't prevent Linux from trying to start new requests
after deletion if it still has the file open locally - something that's
perfectly acceptable on a UNIX system.
Note also that whilst I've marked this as fixing the commit to make cifs
use netfslib, I don't know that it won't occur before that.

Ensure there is enough space before adding MPTCP options in

Without this check, 'remaining' could underflow, and causes issues. If
there is not enough space, MPTCP should not be used.
