We found the issue that ksmbd return STATUS_NO_MORE_FILES response
even though there are still dentries that needs to be read while
file read/write test using framtest utils.
windows client send smb2 query dir request included
OutputBufferLength(128) that is too small to contain even one entry.
This patch make ksmbd immediately returns OutputBufferLength of response

The SMB2 Write packet contains data that is to be written
to a file or to a pipe. Depending on the client, there may
be padding between the header and the data field.
Currently, the length is validated only in the case padding
is present.
Since the DataOffset field always points to the beginning
of the data, there is no need to have a special case for
padding. By removing this, the length is validated in both
cases.

The issue happens in a specific path in smb_check_perm_dacl(). When
"id" and "uid" have the same value, the function simply jumps out of
the loop without decrementing the reference count of the object
"posix_acls", which is increased by get_acl() earlier. This may
result in memory leaks.
Fix it by decreasing the reference count of "posix_acls" before
jumping to label "check_access_bits".

ASoC: meson: Fix event generation for AUI ACODEC mux
...
The last two users were floppy.c and ataflop.c respectively, it was
verified that no other drivers makes use of this, so let's remove it.

This is the last driver making use of fd_request->error_count, which is
easy to get wrong as was shown in floppy.c. We don't need to keep it
there, it can be moved to the atari_floppy_struct instead, so let's do
this.

Interrupt handler bad_flp_intr() may cause a UAF on the recently freed
request just to increment the error count. There's no point keeping
that one in the request anyway, and since the interrupt handler uses a
static pointer to the error which cannot be kept in sync with the
pending request, better make it use a static error counter that's reset
for each new request. This reset now happens when entering
redo_fd_request() for a new request via set_next_request().
One initial concern about a single error counter was that errors on one
floppy drive could be reported on another one, but this problem is not
real given that the driver uses a single drive at a time, as that
PC-compatible controllers also have this limitation by using shared
signals. As such the error count is always for the "current" drive.

A larger collection of fixes than I'd like, mainly because mixer-test
is making it's way into the CI systems and turning up issues on a wider
range of systems. The most substantial thing though is a revert and an
alternative fix for a dmaengine issue where the fix caused disruption
for some other configurations, the core fix is backed out an a driver
specific thing done instead.

- fix the bounds check for the 'gpio-reserved-ranges' device property in
gpiolib-of
- drop the assignment of the pwm base number in gpio-mvebu (this was missed
by the patch doing it globally for all pwm drivers)
- fix the fwnode assignment (use own fwnode, not the parent's one) for the
GPIO irqchip in gpio-visconti
- update the irq_stat field before checking the trigger field in gpio-pca953x
- update GPIO entry in MAINTAINERS

RISC-V: relocate DTB if it's outside memory region
Exit to userspace with an emulation error if KVM encounters an injected
exception with invalid guest state, in addition to the existing check of
bailing if there's a pending exception (KVM doesn't support emulating
exceptions except when emulating real mode via vm86).
In theory, KVM should never get to such a situation as KVM is supposed to
exit to userspace before injecting an exception with invalid guest state.
But in practice, userspace can intervene and manually inject an exception
and/or stuff registers to force invalid guest state while a previously
injected exception is awaiting reinjection.

When one port's input state get inverted (eg. from low to hight) after
pca953x_irq_setup but before setting irq_mask (by some other driver such as
"gpio-keys"), the next inversion of this port (eg. from hight to low) will not
be triggered any more (because irq_stat is not updated at the first time). Issue
should be fixed after this commit.

With CONFIG_FORTIFY_SOURCE enabled, string functions will also perform
dynamic checks for string size which can panic the kernel, like incase
of overflow detection.
In papr_scm, papr_scm_pmu_check_events function uses stat->stat_id with
string operations, to populate the nvdimm_events_map array. Since
stat_id variable is not NULL terminated, the kernel panics with
CONFIG_FORTIFY_SOURCE enabled at boot time.
Below are the logs of kernel panic:

Fix this issue by using kmemdup_nul() to copy the content of
stat->stat_id directly to the nvdimm_events_map array.
mpe: stat->stat_id comes from the hypervisor, not userspace, so there is
no security exposure.

Read requests that return with NRF error are partially completed in
dasd_eckd_ese_read(). The function keeps track of the amount of
processed bytes and the driver will eventually return this information
back to the block layer for further processing via __dasd_cleanup_cqr()
when the request is in the final stage of processing (from the driver's
perspective).
For this, blk_update_request() is used which requires the number of
bytes to complete the request. As per documentation the nr_bytes
parameter is described as follows:
"number of bytes to complete for @req".
This was mistakenly interpreted as "number of bytes _left_ for @req"
leading to new requests with incorrect data length. The consequence are
inconsistent and completely wrong read requests as data from random
memory areas are read back.
Fix this by correctly specifying the amount of bytes that should be used
to complete the request.

When reading unformatted tracks on ESE devices, the corresponding memory
areas are simply set to zero for each segment. This is done incorrectly
for blocksizes < 4096.
There are two problems. First, the increment of dst is done using the
counter of the loop (off), which is increased by blksize every
iteration. This leads to a much bigger increment for dst as actually
intended. Second, the increment of dst is done before the memory area
is set to 0, skipping a significant amount of bytes of memory.
This leads to illegal overwriting of memory and ultimately to a kernel
panic.
This is not a problem with 4k blocksize because
blk_queue_max_segment_size is set to PAGE_SIZE, always resulting in a
single iteration for the inner segment loop (bv.bv_len == blksize). The
incorrectly used 'off' value to increment dst is 0 and the correct
memory area is used.
In order to fix this for blksize < 4k, increment dst correctly using the
blksize and only do it at the end of the loop.

For ESE devices we get an error for write operations on an unformatted
track. Afterwards the track will be formatted and the IO operation
restarted.
When using alias devices a track might be accessed by multiple requests
simultaneously and there is a race window that a track gets formatted
twice resulting in data loss.
Prevent this by remembering the amount of formatted tracks when starting
a request and comparing this number before actually formatting a track
on the fly. If the number has changed there is a chance that the current
track was finally formatted in between. As a result do not format the
track and restart the current IO to check.
The number of formatted tracks does not match the overall number of
formatted tracks on the device and it might wrap around but this is no
problem. It is only needed to recognize that a track has been formatted at
all in between.
