vfs: sanity check the length passed to inode_set_cached_link()
This costs a strlen() call when instatianating a symlink. Preferably it would be hidden behind VFS_WARN_ON (or compatible), but there is no such facility at the moment. With the facility in place the call can be patched out in production kernels. In the meantime, since the cost is being paid unconditionally, use the result to a fixup the bad caller. This is not expected to persist in the long run (tm).

fsnotify: use accessor to set FMODE_NONOTIFY_*
The FMODE_NONOTIFY_* bits are a 2-bits mode. Open coding manipulation of those bits is risky. Use an accessor file_set_fsnotify_mode() to set the mode. Rename file_set_fsnotify_mode() => file_set_fsnotify_mode_from_watchers() to make way for the simple accessor name.

string.h: Use ARRAY_SIZE() for memtostr*()/strtomem*()
The destination argument of memtostr*() and strtomem*() must be a
fixed-size char array at compile time, so there is no need to use
__builtin_object_size() (which is useful for when an argument is
either a pointer or unknown). Instead use ARRAY_SIZE(), which has the
benefit of working around a bug in Clang (fixed[1] in 15+) that got
__builtin_object_size() wrong sometimes.

kbuild: keep symbols for symbol_get() even with CONFIG_TRIM_UNUSED_KSYMS
Linus observed that the symbol_request(utf8_data_table) call fails when
CONFIG_UNICODE=y and CONFIG_TRIM_UNUSED_KSYMS=y.
symbol_get() relies on the symbol data being present in the ksymtab for
symbol lookups. However, EXPORT_SYMBOL_GPL(utf8_data_table) is dropped
due to CONFIG_TRIM_UNUSED_KSYMS, as no module references it in this case.
Probably, this has been broken since commit

net: harmonize tstats and dstats
After the blamed commits below, some UDP tunnel use dstats for
accounting. On the xmit path, all the UDP-base tunnels ends up
using iptunnel_xmit_stats() for stats accounting, and the latter
assumes the relevant (tunnel) network device uses tstats.
The end result is some 'funny' stat report for the mentioned UDP
tunnel, e.g. when no packet is actually dropped and a bunch of
packets are transmitted:
gnv2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1450 qdisc noqueue \
state UNKNOWN mode DEFAULT group default qlen 1000
link/ether ee:7d:09:87:90:ea brd ff:ff:ff:ff:ff:ff
RX: bytes packets errors dropped missed mcast
14916 23 0 15 0 0
TX: bytes packets errors dropped carrier collsns
0 1566 0 0 0 0
Address the issue ensuring the same binary layout for the overlapping
fields of dstats and tstats. While this solution is a bit hackish, is
smaller and with no performance pitfall compared to other alternatives
i.e. supporting both dstat and tstat in iptunnel_xmit_stats() or
reverting the blamed commit.
With time we should possibly move all the IP-based tunnel (and virtual
devices) to dstats.

Updates for timers and timekeeping:
- Properly cast the input to secs_to_jiffies() to unsigned long as
otherwise the result uses the data type of the input variable, which
causes result range checks to fail if the input data type is signed and
smaller than unsigned long.
- Handle late armed hrtimers gracefully on CPU hotplug
There are legitimate cases where a hrtimer is (re)armed on an outgoing
CPU after the timers have been migrated away. This triggers warnings and
caused people to implement horrible workarounds in RCU. But those work
arounds are incomplete and do not cover e.g. the scheduler hrtimers.
Stop this by force moving timer which are enqueued on the current CPU
after timer migration to be queued on a remote online CPU.
This allows to undo the workarounds in a seperate step.
- Demote a warning level printk() to info level in the clocksource
watchdog code as there is no point to emit a warning level message for a
purely informational message.
- Mark a helper function __always_inline and move it into the existing
#ifdef block to avoid 'unused function' warnings from CLANG

Merge tag 'timers-urgent-2025-02-03' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull timer fixes from Thomas Gleixner:
- Properly cast the input to secs_to_jiffies() to unsigned long as
otherwise the result uses the data type of the input variable, which
causes result range checks to fail if the input data type is signed
and smaller than unsigned long.
- Handle late armed hrtimers gracefully on CPU hotplug
There are legitimate cases where a hrtimer is (re)armed on an
outgoing CPU after the timers have been migrated away. This triggers
warnings and caused people to implement horrible workarounds in RCU.
But those workarounds are incomplete and do not cover e.g. the
scheduler hrtimers.
Stop this by force moving timer which are enqueued on the current CPU
after timer migration to be queued on a remote online CPU.
This allows to undo the workarounds in a seperate step.
- Demote a warning level printk() to info level in the clocksource
watchdog code as there is no point to emit a warning level message
for a purely informational message.
- Mark a helper function __always_inline and move it into the existing
#ifdef block to avoid 'unused function' warnings from CLANG

Scenario:
User processe are requesting a large amount of memory and keep page active.
Then a module continuously requests memory from ZONE_DMA32 area.
Memory reclaim will be triggered due to ZONE_DMA32 watermark alarm reached.
However pages in the LRU(active_anon) list are mostly from
the ZONE_NORMAL area.
Reproduce:
Terminal 1: Construct to continuously increase pages active(anon).
mkdir /tmp/memory
mount -t tmpfs -o size=1024000M tmpfs /tmp/memory
dd if=/dev/zero of=/tmp/memory/block bs=4M
tail /tmp/memory/block
Terminal 2:
vmstat -a 1
active will increase.

If increase Active(anon) to 1000G then insmod module triggers
the ZONE_DMA32 watermark. hard lockup will occur.
In my device nr_scanned = 0000000003e3e937 when hard lockup.

About the Fixes:
Why did it take eight years to be discovered?
The problem requires the following conditions to occur:
1. The device memory should be large enough.
2. Pages in the LRU(active_anon) list are mostly from the ZONE_NORMAL area.
3. The memory in ZONE_DMA32 needs to reach the watermark.
If the memory is not large enough, or if the usage design of ZONE_DMA32
area memory is reasonable, this problem is difficult to detect.
notes:
The problem is most likely to occur in ZONE_DMA32 and ZONE_NORMAL,
but other suitable scenarios may also trigger the problem.

block: force noio scope in blk_mq_freeze_queue
When block drivers or the core block code perform allocations with a frozen queue, this could try to recurse into the block device to reclaim memory and deadlock. Thus all allocations done by a process that froze a queue need to be done without __GFP_IO and __GFP_FS. Instead of tying to track all of them down, force a noio scope as part of freezing the queue. Note that nvme is a bit of a mess here due to the non-owner freezes, and they will be addressed separately.

jiffies: Cast to unsigned long in secs_to_jiffies() conversion
While converting users of msecs_to_jiffies(), lkp reported that some range
checks would always be true because of the mismatch between the implied int
value of secs_to_jiffies() vs the unsigned long return value of the
msecs_to_jiffies() calls it was replacing.
Fix this by casting the secs_to_jiffies() input value to unsigned long.

First batch of fixes for 6.14. Nothing really stands out,
but as usual there's a slight concentration of fixes for issues
added in the last two weeks before the MW, and driver bugs
from 6.13 which tend to get discovered upon wider distribution.
Including fixes from IPSec, netfilter and Bluetooth.
Current release - regressions:
- net: revert RTNL changes in unregister_netdevice_many_notify()
- Bluetooth: fix possible infinite recursion of btusb_reset
- eth: adjust locking in some old drivers which protect their state
with spinlocks to avoid sleeping in atomic; core protects
netdev state with a mutex now
Previous releases - regressions:
- eth: mlx5e: make sure we pass node ID, not CPU ID to kvzalloc_node()
- eth: bgmac: reduce max frame size to support just 1500 bytes;
the jumbo frame support would previously cause OOB writes,
but now fails outright
- mptcp: blackhole only if 1st SYN retrans w/o MPC is accepted,
avoid false detection of MPTCP blackholing
Previous releases - always broken:
- mptcp: handle fastopen disconnect correctly
- xfrm: make sure skb->sk is a full sock before accessing its fields
- xfrm: fix taking a lock with preempt disabled for RT kernels
- usb: ipheth: improve safety of packet metadata parsing; prevent
potential OOB accesses
- eth: renesas: fix missing rtnl lock in suspend/resume path

Provide stable parent and name to ->d_revalidate() instances
Most of the filesystem methods where we care about dentry name
and parent have their stability guaranteed by the callers;
->d_revalidate() is the major exception.
It's easy enough for callers to supply stable values for
expected name and expected parent of the dentry being
validated. That kills quite a bit of boilerplate in
->d_revalidate() instances, along with a bunch of races
where they used to access ->d_name without sufficient
precautions.

block: get rid of request queue ->sysfs_dir_lock
The request queue uses ->sysfs_dir_lock for protecting the addition/ deletion of kobject entries under sysfs while we register/unregister blk-mq. However kobject addition/deletion is already protected with kernfs/sysfs internal synchronization primitives. So use of q->sysfs_ dir_lock seems redundant. Moreover, q->sysfs_dir_lock is also used at few other callsites along with q->sysfs_lock for protecting the addition/deletion of kojects. One such example is when we register with sysfs a set of independent access ranges for a disk. Here as well we could get rid off q->sysfs_ dir_lock and only use q->sysfs_lock. The only variable which q->sysfs_dir_lock appears to protect is q-> mq_sysfs_init_done which is set/unset while registering/unregistering blk-mq with sysfs. But use of q->mq_sysfs_init_done could be easily replaced using queue registered bit QUEUE_FLAG_REGISTERED. So with this patch we remove q->sysfs_dir_lock from each callsite and replace q->mq_sysfs_init_done using QUEUE_FLAG_REGISTERED.

Driver core and debugfs updates
Here is the big set of driver core and debugfs updates for 6.14-rc1.
It's coming late in the merge cycle as there are a number of merge
conflicts with your tree now, and I wanted to make sure they were
working properly. To resolve them, look in linux-next, and I will send
the "fixup" patch as a response to the pull request.
Included in here is a bunch of driver core, PCI, OF, and platform rust
bindings (all acked by the different subsystem maintainers), hence the
merge conflict with the rust tree, and some driver core api updates to
mark things as const, which will also require some fixups due to new
stuff coming in through other trees in this merge window.
There are also a bunch of debugfs updates from Al, and there is at least
one user that does have a regression with these, but Al is working on
tracking down the fix for it. In my use (and everyone else's linux-next
use), it does not seem like a big issue at the moment.
Here's a short list of the things in here:
- driver core bindings for PCI, platform, OF, and some i/o functions.
We are almost at the "write a real driver in rust" stage now,
depending on what you want to do.
- misc device rust bindings and a sample driver to show how to use
them
- debugfs cleanups in the fs as well as the users of the fs api for
places where drivers got it wrong or were unnecessarily doing things
in complex ways.
- driver core const work, making more of the api take const * for
different parameters to make the rust bindings easier overall.
- other small fixes and updates
All of these have been in linux-next with all of the aforementioned
merge conflicts, and the one debugfs issue, which looks to be resolved
"soon".

NFSD 6.14 Release Notes
Jeff Layton contributed an implementation of NFSv4.2+ attribute delegation, as described here: https://www.ietf.org/archive/id/draft-ietf-nfsv4-delstid-08.html This interoperates with similar functionality introduced into the Linux NFS client in v6.11. An attribute delegation permits an NFS client to manage a file's mtime, rather than flushing dirty data to the NFS server so that the file's mtime reflects the last write, which is considerably slower. Neil Brown contributed dynamic NFSv4.1 session slot table resizing. This facility enables NFSD to increase or decrease the number of slots per NFS session depending on server memory availability. More session slots means greater parallelism. Chuck Lever fixed a long-standing latent bug where NFSv4 COMPOUND encoding screws up when crossing a page boundary in the encoding buffer. This is a zero-day bug, but hitting it is rare and depends on the NFS client implementation. The Linux NFS client does not happen to trigger this issue. A variety of bug fixes and other incremental improvements fill out the list of commits in this release. Great thanks to all contributors, reviewers, testers, and bug reporters who participated during this development cycle. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEKLLlsBKG3yQ88j7+M2qzM29mf5cFAmeVPBUACgkQM2qzM29m f5dClxAAmW4O2bOJaR8neJ54fzeFYXtFYEXRF/XbIh2KdnCy2LoywT9ux8ndzE0k 1tsjtv0g4y84IcYfrxXPRTuhh2GO2pHw5L1kGVRezJg2ODSFbpdzGtcVK7SIrs2S eijTViqdi9xRgfj1jPqRrvxC99RL3/fmCztqorAPLDFsqYAd/6ZRxZ7+IcZ2h4+J cJ0Z6Wx6eh10roacZPXweH13XJ7xWO/ublYZvQFQpK2BAKyO98aXGgLDraNt8k60 X3DZLSKkGB/eBlNeAlTtcrXec/ot6XGJPKr3b/7zhwfMi8B13RGdSmCR8SxMdRQM vCQO4G2YadU4YFS6FFIw9Wc1XDYUuYh2YgcveafjzjXbgi7NnY7rYOxtnTgBi0Xv XGjtGqpvD676gPm+8b3DcwqmWI3c/WUdtQIZ1uYRCFZdFqkVP91bySPT2aHtx2GO 4j3uEyTlypC00kyvu1oL3+tVUG/EFlJCpYvIbOwqDG2m7KWPStzpfJTD5Q9cdlEl fdgs6l82EVqe1YyjLTqajDuOcRrLYK2hlR/5STc03hQV+GpKSo5UypRejzE9WtRV zT/tyelqhj4+0EZJz4ay/8q9s2Jp+5JGVxoVvjujSuH7+Ulb3T+IDkldtMamO8Fm www2y0/fLfU2xIapMJdCoJ+ZKgel2i8RZMPIc0cIfO5ITXm+dOs= =hwXx -----END PGP SIGNATURE----- Merge tag 'nfsd-6.14' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux Pull nfsd updates from Chuck Lever: "Jeff Layton contributed an implementation of NFSv4.2+ attribute delegation, as described here: https://www.ietf.org/archive/id/draft-ietf-nfsv4-delstid-08.html This interoperates with similar functionality introduced into the Linux NFS client in v6.11.

- Large IIO driver updates and bugfixes
- FPGA driver updates
- Coresight driver updates
- MHI driver updates
- PPS driver updatesa
- const bin_attribute reworking for many drivers
- binder driver updates
- smaller driver updates and fixes

USB / Thunderbolt driver updates for 6.14-rc1
Here is the USB and Thunderbolt driver updates for 6.14-rc1. Nothing
huge in here, just lots of new hardware support and updates for existing
drivers. Changes here are:
- big gadget f_tcm driver update
- other gadget driver updates and fixes
- thunderbolt driver updates for new hardware and capabilities and
lots more debugging functionality to handle it when things aren't
working well.
- xhci driver updates
- new USB-serial device updates
- typec driver updates, including a chrome platform driver (acked by
the subsystem maintainers)
- other small driver updates
All of these have been in linux-next for a while with no reported
issues.

add a string-to-qstr constructor
Quite a few places want to build a struct qstr by given string;
it would be convenient to have a primitive doing that, rather
than open-coding it via QSTR_INIT().
The closest approximation was in bcachefs, but that expands to
initializer list - {.len = strlen(string), .name = string}.
It would be more useful to have it as compound literal -
(struct qstr){.len = strlen(string), .name = string}.
Unlike initializer list it's a valid expression. What's more,
it's a valid lvalue - it's an equivalent of anonymous local
variable with such initializer, so the things like
path->dentry = d_alloc_pseudo(mnt->mnt_sb, &QSTR(name));
are valid. It can also be used as initializer, with identical
effect -
struct qstr x = (struct qstr){.name = s, .len = strlen(s)};
is equivalent to
struct qstr anon_variable = {.name = s, .len = strlen(s)};
struct qstr x = anon_variable;
// anon_variable is never used after that point
and any even remotely sane compiler will manage to collapse that
into
struct qstr x = {.name = s, .len = strlen(s)};
What compound literals can't be used for is initialization of
global variables, but those are covered by QSTR_INIT().
This commit lifts definition(s) of QSTR() into linux/dcache.h,
converts it to compound literal (all bcachefs users are fine
with that) and converts assorted open-coded instances to using
that.

9p: fix ->rename_sem exclusion
9p wants to be able to build a path from given dentry to fs root and keep it valid over a blocking operation. ->s_vfs_rename_mutex would be a natural candidate, but there are places where we need that and where we have no way to tell if ->s_vfs_rename_mutex is already held deeper in callchain. Moreover, it's only held for cross-directory renames; name changes within the same directory happen without it. Solution: * have d_move() done in ->rename() rather than in its caller * maintain a 9p-private rwsem (per-filesystem) * hold it exclusive over the relevant part of ->rename() * hold it shared over the places where we want the path. That almost works. FS_RENAME_DOES_D_MOVE is enough to put all d_move() and d_exchange() calls under filesystem's control. However, there's also __d_unalias(), which isn't covered by any of that. If ->lookup() hits a directory inode with preexisting dentry elsewhere (due to e.g. rename done on server behind our back), d_splice_alias() called by ->lookup() will move/rename that alias. Add a couple of optional methods, so that __d_unalias() would do if alias->d_op->d_unalias_trylock != NULL if (!alias->d_op->d_unalias_trylock(alias)) fail (resulting in -ESTALE from lookup) __d_move(...) if alias->d_op->d_unalias_unlock != NULL alias->d_unalias_unlock(alias) where it currently does __d_move(). 9p instances do down_write_trylock() and up_write() of ->rename_mutex.

nfs: fix ->d_revalidate() UAF on ->d_name accesses
Pass the stable name all the way down to ->rpc_ops->lookup() instances. Note that passing &dentry->d_name is safe in e.g. nfs_lookup() - it *is* stable there, as it is in ->create() et.al. dget_parent() in nfs_instantiate() should be redundant - it'd better be stable there; if it's not, we have more trouble, since ->d_name would also be unsafe in such case. nfs_submount() and nfs4_submount() may or may not require fixes - if they ever get moved on server with fhandle preserved, we are in trouble there... UAF window is fairly narrow here and exfiltration requires the ability to watch the traffic. Reviewed-by: Jeff Layton <jlayton@kernel.org> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> |

Pass parent directory inode and expected name to ->d_revalidate()
->d_revalidate() often needs to access dentry parent and name; that has to be done carefully, since the locking environment varies from caller to caller. We are not guaranteed that dentry in question will not be moved right under us - not unless the filesystem is such that nothing on it ever gets renamed. It can be dealt with, but that results in boilerplate code that isn't even needed - the callers normally have just found the dentry via dcache lookup and want to verify that it's in the right place; they already have the values of ->d_parent and ->d_name stable. There is a couple of exceptions (overlayfs and, to less extent, ecryptfs), but for the majority of calls that song and dance is not needed at all. It's easier to make ecryptfs and overlayfs find and pass those values if there's a ->d_revalidate() instance to be called, rather than doing that in the instances. This commit only changes the calling conventions; making use of supplied values is left to followups. NOTE: some instances need more than just the parent - things like CIFS may need to build an entire path from filesystem root, so they need more precautions than the usual boilerplate. This series doesn't do anything to that need - these filesystems have to keep their locking mechanisms (rename_lock loops, use of dentry_path_raw(), private rwsem a-la v9fs). One thing to keep in mind when using name is that name->name will normally point into the pathname being resolved; the filename in question occupies name->len bytes starting at name->name, and there is NUL somewhere after it, but it the next byte might very well be '/' rather than '\0'. Do not ignore name->len. Reviewed-by: Jeff Layton <jlayton@kernel.org> Reviewed-by: Gabriel Krisman Bertazi <gabriel@krisman.be> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> |

pwm: Two fixes for the pwm core and the pwm-microchip-core driver
Conor Dooley found and fixed a problem in the pwm-microchip-core driver that existed since the driver's birth in v6.5-rc1. It's about a corner case that only happens if two pwm devices of the same chip are set to the same long period. The other problem is about the new pwm API that currently is only supported by two hardware drivers. The fix prevents a NULL pointer exception if one of the new functions is called for a pwm device with a driver that only provides the old callbacks. -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEP4GsaTp6HlmJrf7Tj4D7WH0S/k4FAmeXs+8ACgkQj4D7WH0S /k4zqQgAs6b6PWu99Bh59WbLtqdpo3GfBrxXEGajYfG/rl/WCqTaaR0drQGE+Mlz oqJrJ9klO02JcnPh7tyUi8oIDGm+zJ5Y6au60Ry5aDvZCh370RlXWrqaVJO9dK1k rWfko7rI2/7LFmrpn9Ass/RNjWcL2c/7C9b+NiXfrHlcgdSq49tjBziN6adCOnrF NtOjnAD9jalVxHEaS9z3rhdE714XLvR/NtevzQX5fp9rZylENKrVta0FZnJMX7uD OE6OhsxSyo4nuVpHgL9YLg45JTgzHzIyCJ+GTO0Cjk9oD1UHBKxiv2zOw5j4tBt4 PAQ/yZ10kwJ9IF4j8bxTFYg3PLItLQ== =EWDl -----END PGP SIGNATURE----- Merge tag 'pwm/for-6.14-rc1-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/ukleinek/linux Pull pwm fixes from Uwe Kleine-König: "Two fixes.

power supply and reset changes for the 6.14 series
* power-supply core
- introduce power supply extensions, which allows adding properties to
a power supply device from a separate driver. This will be used
initially to extend the generic ACPI charger/battery driver with
vendor extensions for charge thresholds.
- convert all drivers from power_supply_for_each_device to new
power_supply_for_each_psy(), which avoids lots of casting being
done in the drivers.
- avoid LED trigger like values in uevent for POWER_SUPPLY_PROP_CHARGE_BEHAVIOUR
- introduce POWER_SUPPLY_PROP_CHARGE_TYPES, which is similar to the
POWER_SUPPLY_PROP_CHARGE_TYPE property, but also lists the available
options on the specific platform
* power-supply drivers
- dell-laptop: use new power_supply_charge_types_show/_parse helpers
- stc3117: new driver for equally named fuel gauge chip
- bq24190: add support for new POWER_SUPPLY_PROP_CHARGE_TYPES

- max1720x: add charge full property
- max1720x: support extra thermistor temperatures
- max17042: add max77705 support
