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.

Merge tag 'pull-revalidate' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull vfs d_revalidate updates from Al Viro:
"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"

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".

KVM/arm64 updates for 6.14
* New features:
- Support for non-protected guest in protected mode, achieving near
feature parity with the non-protected mode
- Support for the EL2 timers as part of the ongoing NV support
- Allow control of hardware tracing for nVHE/hVHE
* Improvements, fixes and cleanups:
- Massive cleanup of the debug infrastructure, making it a bit less
awkward and definitely easier to maintain. This should pave the
way for further optimisations
- Complete rewrite of pKVM's fixed-feature infrastructure, aligning
it with the rest of KVM and making the code easier to follow
- Large simplification of pKVM's memory protection infrastructure
- Better handling of RES0/RES1 fields for memory-backed system
registers
- Add a workaround for Qualcomm's Snapdragon X CPUs, which suffer
from a pretty nasty timer bug
- Small collection of cleanups and low-impact fixes

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.

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.

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> |

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

Pull power supply and reset updates from Sebastian Reichel:
"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

The various patchsets are summarized below. Plus of course many
indivudual patches which are described in their changelogs. - "Allocate and free frozen pages" from Matthew Wilcox reorganizes the page allocator so we end up with the ability to allocate and free zero-refcount pages. So that callers (ie, slab) can avoid a refcount inc & dec. - "Support large folios for tmpfs" from Baolin Wang teaches tmpfs to use large folios other than PMD-sized ones. - "Fix mm/rodata_test" from Petr Tesarik performs some maintenance and fixes for this small built-in kernel selftest. - "mas_anode_descend() related cleanup" from Wei Yang tidies up part of the mapletree code. - "mm: fix format issues and param types" from Keren Sun implements a few minor code cleanups. - "simplify split calculation" from Wei Yang provides a few fixes and a test for the mapletree code. - "mm/vma: make more mmap logic userland testable" from Lorenzo Stoakes continues the work of moving vma-related code into the (relatively) new mm/vma.c. - "mm/page_alloc: gfp flags cleanups for alloc_contig_*()" from David Hildenbrand cleans up and rationalizes handling of gfp flags in the page allocator. - "readahead: Reintroduce fix for improper RA window sizing" from Jan Kara is a second attempt at fixing a readahead window sizing issue. It should reduce the amount of unnecessary reading. - "synchronously scan and reclaim empty user PTE pages" from Qi Zheng addresses an issue where "huge" amounts of pte pagetables are accumulated (https://lore.kernel.org/lkml/cover.1718267194.git.zhengqi.arch@bytedance.com/). Qi's series addresses this windup by synchronously freeing PTE memory within the context of madvise(MADV_DONTNEED). - "selftest/mm: Remove warnings found by adding compiler flags" from Muhammad Usama Anjum fixes some build warnings in the selftests code when optional compiler warnings are enabled. - "mm: don't use __GFP_HARDWALL when migrating remote pages" from David Hildenbrand tightens the allocator's observance of __GFP_HARDWALL. - "pkeys kselftests improvements" from Kevin Brodsky implements various fixes and cleanups in the MM selftests code, mainly pertaining to the pkeys tests. - "mm/damon: add sample modules" from SeongJae Park enhances DAMON to estimate application working set size. - "memcg/hugetlb: Rework memcg hugetlb charging" from Joshua Hahn provides some cleanups to memcg's hugetlb charging logic. - "mm/swap_cgroup: remove global swap cgroup lock" from Kairui Song removes the global swap cgroup lock. A speedup of 10% for a tmpfs-based kernel build was demonstrated. - "zram: split page type read/write handling" from Sergey Senozhatsky has several fixes and cleaups for zram in the area of zram_write_page(). A watchdog softlockup warning was eliminated. - "move pagetable_*_dtor() to __tlb_remove_table()" from Kevin Brodsky cleans up the pagetable destructor implementations. A rare use-after-free race is fixed. - "mm/debug: introduce and use VM_WARN_ON_VMG()" from Lorenzo Stoakes simplifies and cleans up the debugging code in the VMA merging logic. - "Account page tables at all levels" from Kevin Brodsky cleans up and regularizes the pagetable ctor/dtor handling. This results in improvements in accounting accuracy. - "mm/damon: replace most damon_callback usages in sysfs with new core functions" from SeongJae Park cleans up and generalizes DAMON's sysfs file interface logic. - "mm/damon: enable page level properties based monitoring" from SeongJae Park increases the amount of information which is presented in response to DAMOS actions. - "mm/damon: remove DAMON debugfs interface" from SeongJae Park removes DAMON's long-deprecated debugfs interfaces. Thus the migration to sysfs is completed. - "mm/hugetlb: Refactor hugetlb allocation resv accounting" from Peter Xu cleans up and generalizes the hugetlb reservation accounting. - "mm: alloc_pages_bulk: small API refactor" from Luiz Capitulino removes a never-used feature of the alloc_pages_bulk() interface. - "mm/damon: extend DAMOS filters for inclusion" from SeongJae Park extends DAMOS filters to support not only exclusion (rejecting), but also inclusion (allowing) behavior. - "Add zpdesc memory descriptor for zswap.zpool" from Alex Shi "introduces a new memory descriptor for zswap.zpool that currently overlaps with struct page for now. This is part of the effort to reduce the size of struct page and to enable dynamic allocation of memory descriptors." - "mm, swap: rework of swap allocator locks" from Kairui Song redoes and simplifies the swap allocator locking. A speedup of 400% was demonstrated for one workload. As was a 35% reduction for kernel build time with swap-on-zram. - "mm: update mips to use do_mmap(), make mmap_region() internal" from Lorenzo Stoakes reworks MIPS's use of mmap_region() so that mmap_region() can be made MM-internal. - "mm/mglru: performance optimizations" from Yu Zhao fixes a few MGLRU regressions and otherwise improves MGLRU performance. - "Docs/mm/damon: add tuning guide and misc updates" from SeongJae Park updates DAMON documentation. - "Cleanup for memfd_create()" from Isaac Manjarres does that thing. - "mm: hugetlb+THP folio and migration cleanups" from David Hildenbrand provides various cleanups in the areas of hugetlb folios, THP folios and migration. - "Uncached buffered IO" from Jens Axboe implements the new RWF_DONTCACHE flag which provides synchronous dropbehind for pagecache reading and writing. To permite userspace to address issues with massive buildup of useless pagecache when reading/writing fast devices. - "selftests/mm: virtual_address_range: Reduce memory" from Thomas Weißschuh fixes and optimizes some of the MM selftests. -----BEGIN PGP SIGNATURE----- iHUEABYKAB0WIQTTMBEPP41GrTpTJgfdBJ7gKXxAjgUCZ5a+cwAKCRDdBJ7gKXxA jtoyAP9R58oaOKPJuTizEKKXvh/RpMyD6sYcz/uPpnf+cKTZxQEAqfVznfWlw/Lz uC3KRZYhmd5YrxU4o+qjbzp9XWX/xAE= =Ib2s -----END PGP SIGNATURE----- Merge tag 'mm-stable-2025-01-26-14-59' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Pull MM updates from Andrew Morton: "The various patchsets are summarized below.

ksm: add ksm involvement information for each process
In /proc/<pid>/ksm_stat, add two extra ksm involvement items including
KSM_mergeable and KSM_merge_any. It helps administrators to better know
the system's KSM behavior at process level.
ksm_merge_any: yes/no
whether the process'mm is added by prctl() into the candidate list
of KSM or not, and fully enabled at process level.
ksm_mergeable: yes/no
whether any VMAs of the process'mm are currently applicable to KSM.
Purpose
=======
These two items are just to improve the observability of KSM at process
level, so that users can know if a certain process has enabled KSM.
For example, if without these two items, when we look at
/proc/<pid>/ksm_stat and there's no merging pages found, We are not sure
whether it is because KSM was not enabled or because KSM did not
successfully merge any pages.
Although "mg" in /proc/<pid>/smaps indicate VM_MERGEABLE, it's opaque
and not very obvious for non professionals.

Docs/admin-guide/mm/damon/start: update snapshot example
Two of DAMON user-space tool (damo) commands that are used for examples on DAMON getting started document, namely 'damo show' and 'damo report heats' are deprecated[1,2], and replaced by new commands that provides same functions with unified and simplified user interfaces. Also the example output of 'damo show' is outdated. 'damo schemes' command is not deprecated, but users are recommended to use 'damo start' or 'damo tune' instead. Update the examples to use the replacements, recommendations, and up-to-date output formats.

Docs/admin-guide/mm/damon/usage: fix and add missing DAMOS filter sysfs files on files hierarchy
DAMOS filter directory part of DAMON sysfs files hierarchy on the usage document is wrong. 'memcg_path' file under the directory is wrongly written as 'memcg_id'. Also the directory has 'addr_start', 'addr_end', and 'target_idx' files, but the list is missing those. Fix the wrong name and add missing files.

Docs/mm/damon: add an example monitoring intervals tuning
Add a DAMON monitoring intervals tuning example that contains output from a demonstration of the guide on a real server workload system. The example with real world numbers will help users better understanding the guide instructions and what outputs they can expect and verify. Those will again help finding the rooms for improvements on the guide.

Docs/mm/damon/design: add monitoring parameters tuning guide
Patch series "Docs/mm/damon: add tuning guide and misc updates". Add DAMON monitoring parameters tuning guide (patches 1 and 2), with misc documentation fixes (patch 3), updates (patch 4) and clarifications (patch 5). This patch (of 5): DAMON monitoring parameters including sampling and aggregation intervals should be tuned for given workloads. However, the fact is not explicitly documented. Also there is no official guide to help the tuning. This apparently confused a number of people[1] at best, or made people forgive DAMON without tuning. Add a guide on the design document.

Docs/translations/*/admin-guide/mm/damon/usage: remove DAMON debugfs interface documentation
Patch series "mm/damon: remove DAMON debugfs interface". DAMON debugfs interface was the only user interface of DAMON at the beginning[1]. However, it turned out the interface would be not good enough for long-term flexibility and stability. In Feb 2022[2], we therefore introduced DAMON sysfs interface as an alternative user interface that aims long-term flexibility and stability. With its introduction, DAMON debugfs interface has announced to be deprecated in near future. In Feb 2023[3], we announced the official deprecation of DAMON debugfs interface. In Jan 2024[4], we further made the deprecation difficult to be ignored. In Oct 2024[5], we posted an RFC version of this patch series as the last notice. And as of this writing, no problem or concerns about the removal plan have reported. Apparently users are already moved to the alternative, or made good plans for the change. Remove the DAMON debugfs interface code from the tree. Given the past timeline and the absence of reported problems or concerns, it is safe enough to be done.
