c5178e6ca6 workqueue: Make rescuer initialization as the last step of the creation of a new wq
For early wq allocation, rescuer initialization is the last step of the
creation of a new wq.  Make the behavior the same for all allocations.

Prepare for initializing rescuer's affinities with the default pwq's
affinities.

Prepare for moving the whole workqueue initializing procedure into
wq_pool_mutex and cpu hotplug locks.

7c73ddb758 jbd2: speed up jbd2_transaction_committed()
jbd2_transaction_committed() is used to check whether a transaction with
the given tid has already committed, it holds j_state_lock in read mode
and check the tid of current running transaction and committing
transaction, but holding the j_state_lock is expensive.

We have already stored the sequence number of the most recently
committed transaction in journal t->j_commit_sequence, we could do this
check by comparing it with the given tid instead. If the given tid isn't
smaller than j_commit_sequence, we can ensure that the given transaction
has been committed. That way we could drop the expensive lock and
achieve about 10% ~ 20% performance gains in concurrent DIOs on may
virtual machine with 100G ramdisk.

vfs: don't mod negative dentry count when on shrinker list
The nr_dentry_negative counter is intended to only account negative
dentries that are present on the superblock LRU. Therefore, the LRU
add, remove and isolate helpers modify the counter based on whether
the dentry is negative, but the shrinker list related helpers do not
modify the counter, and the paths that change a dentry between
positive and negative only do so if DCACHE_LRU_LIST is set.

The problem with this is that a dentry on a shrinker list still has
DCACHE_LRU_LIST set to indicate ->d_lru is in use. The additional
DCACHE_SHRINK_LIST flag denotes whether the dentry is on LRU or a
shrink related list. Therefore if a relevant operation (i.e. unlink)
occurs while a dentry is present on a shrinker list, and the
associated codepath only checks for DCACHE_LRU_LIST, then it is
technically possible to modify the negative dentry count for a
dentry that is off the LRU. Since the shrinker list related helpers
do not modify the negative dentry count (because non-LRU dentries
should not be included in the count) when the dentry is ultimately
removed from the shrinker list, this can cause the negative dentry
count to become permanently inaccurate.

This problem can be reproduced via a heavy file create/unlink vs.
drop_caches workload. On an 80xcpu system, I start 80 tasks each
running a 1k file create/delete loop, and one task spinning on
drop_caches. After 10 minutes or so of runtime, the idle/clean cache
negative dentry count increases from somewhere in the range of 5-10
entries to several hundred (and increasingly grows beyond
nr_dentry_unused).

Tweak the logic in the paths that turn a dentry negative or positive
to filter out the case where the dentry is present on a shrink
related list. This allows the above workload to maintain an accurate
negative dentry count.

filelock: fix potential use-after-free in posix_lock_inode
Light Hsieh reported a KASAN UAF warning in trace_posix_lock_inode().
The request pointer had been changed earlier to point to a lock entry
that was added to the inode's list. However, before the tracepoint could
fire, another task raced in and freed that lock.

Fix this by moving the tracepoint inside the spinlock, which should
ensure that this doesn't happen.

Merge patch series "cachefiles: random bugfixes"
libaokun@huaweicloud.com <libaokun@huaweicloud.com> says:

This is the third version of this patch series, in which another patch set
is subsumed into this one to avoid confusing the two patch sets.
(https://patchwork.kernel.org/project/linux-fsdevel/list/?series=854914)

We've been testing ondemand mode for cachefiles since January, and we're
almost done. We hit a lot of issues during the testing period, and this
patch series fixes some of the issues. The patches have passed internal
testing without regression.

The following is a brief overview of the patches, see the patches for
more details.

Patch 1-2: Add fscache_try_get_volume() helper function to avoid
fscache_volume use-after-free on cache withdrawal.

Patch 3: Fix cachefiles_lookup_cookie() and cachefiles_withdraw_cache()
concurrency causing cachefiles_volume use-after-free.

Patch 4: Propagate error codes returned by vfs_getxattr() to avoid
endless loops.

Patch 5-7: A read request waiting for reopen could be closed maliciously
before the reopen worker is executing or waiting to be scheduled. So
ondemand_object_worker() may be called after the info and object and even
the cache have been freed and trigger use-after-free. So use
cancel_work_sync() in cachefiles_ondemand_clean_object() to cancel the
reopen worker or wait for it to finish. Since it makes no sense to wait
for the daemon to complete the reopen request, to avoid this pointless
operation blocking cancel_work_sync(), Patch 1 avoids request generation
by the DROPPING state when the request has not been sent, and Patch 2
flushes the requests of the current object before cancel_work_sync().

Patch 8: Cyclic allocation of msg_id to avoid msg_id reuse misleading
the daemon to cause hung.

Patch 9: Hold xas_lock during polling to avoid dereferencing reqs causing
use-after-free. This issue was triggered frequently in our tests, and we
found that anolis 5.10 had fixed it. So to avoid failing the test, this
patch is pushed upstream as well.

Baokun Li (7):
  netfs, fscache: export fscache_put_volume() and add
    fscache_try_get_volume()
  cachefiles: fix slab-use-after-free in fscache_withdraw_volume()

  cachefiles: propagate errors from vfs_getxattr() to avoid infinite

e2e33caa5d ksmbd: discard write access to the directory open
may_open() does not allow a directory to be opened with the write access.
However, some writing flags set by client result in adding write access
on server, making ksmbd incompatible with FUSE file system. Simply, let's
discard the write access when opening a directory.

1c510c7d82 arm64: dts: add description for solidrun cn9130 som and clearfog boards
Add description for the SolidRun CN9130 SoM, and Clearfog Base / Pro
reference boards.

The SoM has been designed as a pin-compatible replacement for the older
Armada 388 based SoM. Therefore it supports the same boards and a
similar feature set.

Most notable upgrades:
- 4x Cortex-A72
- 10Gbps SFP
- Both eMMC and SD supported at the same time

The developer first supporting this product at SolidRun decided to use
different filenames for the DTBs: Armada 388 uses the full
"clearfog" string while cn9130 uses the abbreviation "cf".
This name is already hard-coded in pre-installed vendor u-boot and can
not be changed easily.

NOTICE IN CASE ANYBODY WANTS TO SELF-UPGRADE:
CN9130 SoM has a different footprint from Armada 388 SoM.
Components on the carrier board below the SoM may collide causing
damage, such as on Clearfog Base.

Add bindings for the SolidRun CN9132 COM-Express Type 7 evaluation board.
The CEX is based on CN9130 SoC and includes two southbridges.

Because CN9132 and 9131 are just names for different designs around the

5f5eb24090 dt-bindings: arm64: marvell: add solidrun cn9130 som based boards
Add bindings for SolidRun boards based on CN9130 SoM.

Three boards are added in total:
- Clearfog Base
- Clearfog Pro
- SolidWAN
The Clearfog boards are identical to the older Armada 388 based boards,
upgraded with a new SoM and SoC.
However the feature set and performance characteristics are different,
therefore compatible strings from armada 388 versions are not included.

SolidWAN uses the same SoM adding a southbridge on the carrier.

Since 2019 there are bindings in-tree for two boards based on cn9130 and
9131. These are extremely verbose by listing cn9132, cn9131, cn9130,
ap807-quad, ap807 for the SoC alone.
CN9130 SoC combines an application processor (ap807) and a
communication processor (cp115) in a single package.

The communication processor (short CP) is also available separately as a
southbridge. It only functions in combination with the CN9130 SoC.
Complete systems adding one or two southbridges are by convention called
CN9131 and CN9132 respectively.
Despite different naming all systems are built around the same SoC.
Therefore marvell,cn9131 and marvell,cn9132 can be omitted. The number
of CPs is part of a board's BoM and can be reflected in the board
compatible string instead.

Existing bindings also describe cn9130 as a specialisation of
ap807-quad. Usually board-level compatibles stop at the SoC without
going into silicon versions or individual dies.
There is no programming model at this layer, and in particular not for
parts of an SoC. Therefore the ap compatibles can also be omitted.

cfa65ef7c8 ARM: dts: turris-omnia: Add MCU system-controller node
Turris Omnia's MCU provides various features that can be configured over
I2C at address 0x2a. Add device-tree node.

This does not carry a Fixes tag - we do not want this to get backported
to stable kernels for the following reason: U-Boot since v2022.10
inserts a phy-reset-gpio property into the WAN ethernet node pointing to
the MCU node if it finds the MCU node with a cznic,turris-omnia-mcu
compatible. Thus if this change got backported to a stable kernel, the
WAN interface driver would defer probe indefinitely (since it would wait
for the turris-omnia-mcu driver which would not be present).
