ASoC: 88pm860x: refactor deprecated strncpy
`strncpy` is deprecated for use on NUL-terminated destination strings [1].
A suitable replacement is `strscpy` [2] due to the fact that it
guarantees NUL-termination on its destination buffer argument which is
_not_ always the case for `strncpy`!
In this case, though, there was care taken to ensure that the
destination buffer would be NUL-terminated. The destination buffer is
zero-initialized and each `pm860x->name[i]` has a size of
`MAX_NAME_LENGTH + 1`. This means that there is unlikely to be a bug
here.
However, in an attempt to eliminate the usage of the `strncpy` API as
well as disambiguate implementations, replacements such as: `strscpy`,
`strscpy_pad`, `strtomem` and `strtomem_pad` should be preferred.
We are able to eliminate the need for `len + 1` since `strscpy`
guarantees NUL-termination for its destination buffer as per its
implementation [3]:
| /* Hit buffer length without finding a NUL; force NUL-termination. */
| if (res)
| dest[res-1] = '\0';

ASoC: cs35l56: Move shared data into a common data structure
The ASoC and HDA drivers have structures that contain some of the same
information - instead of maintaining two locations for this data the
drivers should share a common data structure as this will enable common
utility functions to be created.
The first step is to move the location of these members in the ASoC
driver.

kbuild: rust: avoid creating temporary files
`rustc` outputs by default the temporary files (i.e. the ones saved
by `-Csave-temps`, such as `*.rcgu*` files) in the current working
directory when `-o` and `--out-dir` are not given (even if
`--emit=x=path` is given, i.e. it does not use those for temporaries).
Since out-of-tree modules are compiled from the `linux` tree,
`rustc` then tries to create them there, which may not be accessible.
Thus pass `--out-dir` explicitly, even if it is just for the temporary
files.
Similarly, do so for Rust host programs too.

"Add minor debugging improvement.
The change improves ability to read a network trace to debug problems
on encrypted connections which are very common (e.g. using wireshark
or tcpdump).
That works today with tools like 'smbinfo keys /mnt/file' but requires
passing in a filename on the mount (see e.g. [1]), but it often makes
more sense to just pass in the mount point path (ie a directory not a
filename).
So this fix was needed to debug some types of problems (an obvious
example is on an encrypted connection failing operations on an empty
share or with no files in the root of the directory) - so you can
simply pass in the 'smbinfo keys <mntpoint>' and get the information
that wireshark needs"

ring-buffer: Do not swap cpu_buffer during resize process
When ring_buffer_swap_cpu was called during resize process,
the cpu buffer was swapped in the middle, resulting in incorrect state.
Continuing to run in the wrong state will result in oops.
This issue can be easily reproduced using the following two scripts:
/tmp # cat test1.sh
//#! /bin/sh
for i in `seq 0 100000`
do
echo 2000 > /sys/kernel/debug/tracing/buffer_size_kb
sleep 0.5
echo 5000 > /sys/kernel/debug/tracing/buffer_size_kb
sleep 0.5
done
/tmp # cat test2.sh

for i in `seq 0 100000`
do
echo irqsoff > /sys/kernel/debug/tracing/current_tracer
sleep 1
echo nop > /sys/kernel/debug/tracing/current_tracer
sleep 1
done
/tmp # ./test1.sh &
/tmp # ./test2.sh &
A typical oops log is as follows, sometimes with other different oops logs.

ext4: fix rbtree traversal bug in ext4_mb_use_preallocated
During allocations, while looking for preallocations(PA) in the per
inode rbtree, we can't do a direct traversal of the tree because
ext4_mb_discard_group_preallocation() can paralelly mark the pa deleted
and that can cause direct traversal to skip some entries. This was
leading to a BUG_ON() being hit [1] when we missed a PA that could satisfy
our request and ultimately tried to create a new PA that would overlap
with the missed one.
To makes sure we handle that case while still keeping the performance of
the rbtree, we make use of the fact that the only pa that could possibly
overlap the original goal start is the one that satisfies the below
conditions:
1. It must have it's logical start immediately to the left of
(ie less than) original logical start.
2. It must not be deleted
To find this pa we use the following traversal method:
1. Descend into the rbtree normally to find the immediate neighboring
PA. Here we keep descending irrespective of if the PA is deleted or if
it overlaps with our request etc. The goal is to find an immediately
adjacent PA.
2. If the found PA is on right of original goal, use rb_prev() to find
the left adjacent PA.
3. Check if this PA is deleted and keep moving left with rb_prev() until
a non deleted PA is found.
4. This is the PA we are looking for. Now we can check if it can satisfy
the original request and proceed accordingly.
This approach also takes care of having deleted PAs in the tree.
(While we are at it, also fix a possible overflow bug in calculating the
end of a PA)

ext4: correct inline offset when handling xattrs in inode body
When run on a file system where the inline_data feature has been
enabled, xfstests generic/269, generic/270, and generic/476 cause ext4
to emit error messages indicating that inline directory entries are
corrupted. This occurs because the inline offset used to locate
inline directory entries in the inode body is not updated when an
xattr in that shared region is deleted and the region is shifted in
memory to recover the space it occupied. If the deleted xattr precedes
the system.data attribute, which points to the inline directory entries,
that attribute will be moved further up in the region. The inline
offset continues to point to whatever is located in system.data's former
location, with unfortunate effects when used to access directory entries
or (presumably) inline data in the inode body.

In order to avoid disturbing anything drop the initial fixes and

originally noticed, a more substantial refactoring of the API which
ensures that all buses make the same assumptions will follow.
- The generic regcache code had been forcing on async I/O which did
not work with the new maple tree sync code when used with SPI.
Since that was mainly for the rbtree cache and the assumptions
about hardware that drove the choice are probably not true any more
fix this by pushing the enablement of async down into the rbtree

This probably also makes cache syncs for systems faster though it's
not the point.
- The test code was triggering use of the rbtree and maple tree

loop: do not enforce max_loop hard limit by (new) default
Problem:
The max_loop parameter is used for 2 different purposes:
1) initial number of loop devices to pre-create on init
2) maximum number of loop devices to add on access/open()
Historically, its default value (zero) caused 1) to create non-zero
number of devices (CONFIG_BLK_DEV_LOOP_MIN_COUNT), and no hard limit on
2) to add devices with autoloading.
However, the default value changed in commit
85c50197716c ("loop: Fix
the max_loop commandline argument treatment when it is set to 0") to
CONFIG_BLK_DEV_LOOP_MIN_COUNT, for max_loop=0 not to pre-create devices.
That does improve 1), but unfortunately it breaks 2), as the default
behavior changed from no-limit to hard-limit.
Example:
For example, this userspace code broke for N >= CONFIG, if the user
relied on the default value 0 for max_loop:
mknod("/dev/loopN");
open("/dev/loopN"); // now fails with ENXIO
Though affected users may "fix" it with (loop.)max_loop=0, this means to
require a kernel parameter change on stable kernel update (that commit
Fixes: an old commit in stable).
Solution:
The original semantics for the default value in 2) can be applied if the
parameter is not set (ie, default behavior).
This still keeps the intended function in 1) and 2) if set, and that
commit's intended improvement in 1) if max_loop=0.
Before
85c50197716c:
- default: 1) CONFIG devices 2) no limit
- max_loop=0: 1) CONFIG devices 2) no limit
- max_loop=X: 1) X devices 2) X limit
After
85c50197716c:
- default: 1) CONFIG devices 2) CONFIG limit (*)
- max_loop=0: 1) 0 devices (*) 2) no limit
- max_loop=X: 1) X devices 2) X limit
This commit:
- default: 1) CONFIG devices 2) no limit (*)
- max_loop=0: 1) 0 devices 2) no limit
- max_loop=X: 1) X devices 2) X limit
Future:
The issue/regression from that commit only affects code under the
CONFIG_BLOCK_LEGACY_AUTOLOAD deprecation guard, thus the fix too is
contained under it.
Once that deprecated functionality/code is removed, the purpose 2) of
max_loop (hard limit) is no longer in use, so the module parameter
description can be changed then.

Unfortunately this way isn't enough, cause waiter can be added to wait
queue just after it is woken up.
Follows one example(64 depth, wake_batch is 8)
1) all 64 tags are active
2) in each wait queue, there is only one single waiter
3) each time one completion batch(8 completions) wakes up just one
waiter in each wait queue, then immediately one new sleeper is added
to this wait queue
4) after 64 completions, 8 waiters are wakeup, and there are still 8
waiters in each wait queue
5) after another 8 active tags are completed, only one waiter can be
wakeup, and the other 7 can't be waken up anymore.
Turns out it isn't easy to fix this problem, so simply wakeup enough
waiters for single batch.

drm/atomic: Fix potential use-after-free in nonblocking commits
This requires a bit of background. Properly done a modeset driver's
unload/remove sequence should be
drm_dev_unplug();
drm_atomic_helper_shutdown();
drm_dev_put();
The trouble is that the drm_dev_unplugged() checks are by design racy,
they do not synchronize against all outstanding ioctl. This is because
those ioctl could block forever (both for modeset and for driver
specific ioctls), leading to deadlocks in hotunplug. Instead the code
sections that touch the hardware need to be annotated with
drm_dev_enter/exit, to avoid accessing hardware resources after the
unload/remove has finished.
To avoid use-after-free issues all the involved userspace visible
objects are supposed to hold a reference on the underlying drm_device,
like drm_file does.
The issue now is that we missed one, the atomic modeset ioctl can be run
in a nonblocking fashion, and in that case it cannot rely on the implied
drm_device reference provided by the ioctl calling context. This can
result in a use-after-free if an nonblocking atomic commit is carefully
raced against a driver unload.
Fix this by unconditionally grabbing a drm_device reference for any
drm_atomic_state structures. Strictly speaking this isn't required for
blocking commits and TEST_ONLY calls, but it's the simpler approach.
Thanks to shanzhulig for the initial idea of grabbing an unconditional
reference, I just added comments, a condensed commit message and fixed a
minor potential issue in where exactly we drop the final reference.

ia64: mmap: Consider pgoff when searching for free mapping
IA64 is the only architecture which does not consider the pgoff value when
searching for a possible free memory region with vm_unmapped_area().
Adding this seems to have no negative side effect on IA64, so add it now
to make IA64 consistent with all other architectures.

io_uring: Fix io_uring mmap() by using architecture-provided get_unmapped_area()
The io_uring testcase is broken on IA-64 since commit
d808459b2e31
("io_uring: Adjust mapping wrt architecture aliasing requirements").
The reason is, that this commit introduced an own architecture
independend get_unmapped_area() search algorithm which finds on IA-64 a
memory region which is outside of the regular memory region used for
shared userspace mappings and which can't be used on that platform
due to aliasing.
To avoid similar problems on IA-64 and other platforms in the future,
it's better to switch back to the architecture-provided
get_unmapped_area() function and adjust the needed input parameters
before the call. Beside fixing the issue, the function now becomes
easier to understand and maintain.
This patch has been successfully tested with the io_uring testcase on
physical x86-64, ppc64le, IA-64 and PA-RISC machines. On PA-RISC the LTP
mmmap testcases did not report any regressions.

arm64/fpsimd: Ensure SME storage is allocated after SVE VL changes
When we reconfigure the SVE vector length we discard the backing storage
for the SVE vectors and then reallocate on next SVE use, leaving the SME
specific state alone. This means that we do not enable SME traps if they
were already disabled. That means that userspace code can enter streaming
mode without trapping, putting the task in a state where if we try to save
the state of the task we will fault.
Since the ABI does not specify that changing the SVE vector length disturbs
SME state, and since SVE code may not be aware of SME code in the process,
we shouldn't simply discard any ZA state. Instead immediately reallocate
the storage for SVE, and disable SME if we change the SVE vector length
while there is no SME state active.
Disabling SME traps on SVE vector length changes would make the overall
code more complex since we would have a state where we have valid SME state
stored but might get a SME trap.

blk-iocost: skip empty flush bio in iocost
The flush bio may have data, may have no data (empty flush), we couldn't
calculate cost for empty flush bio. So we'd better just skip it for now.
Another side effect is that empty flush bio's bio_end_sector() is 0, cause
iocg->cursor reset to 0, may break the cost calculation of other bios.
This isn't good enough, since flush bio still consume the device bandwidth,
but flush request is special, can be merged randomly in the flush state
machine, we don't know how to calculate cost for it for now.
Its completion time also has flaws, which may include the pre-flush or
post-flush completion time, but I don't know if we need to fix that and
how to fix it.

io_uring: treat -EAGAIN for REQ_F_NOWAIT as final for io-wq
io-wq assumes that an issue is blocking, but it may not be if the
request type has asked for a non-blocking attempt. If we get
-EAGAIN for that case, then we need to treat it as a final result
and not retry or arm poll for it.
