pwm: Changes for v6.12-rc1
This pull request contains some cleanups to the core and some mostly minor updates to a bunch of drivers and device tree bindings. One thing worth pointing out is that it contains an immutable branch containing support for a new mfd chip (Analog Devices ADP5585) with several sub drivers. So expect to get the four affected commits also from my fellow MFD and GPIO maintainers. Thanks go to Andrew Kreimer, Clark Wang, Conor Dooley, David Lechner, Dmitry Rokosov, Frank Li, Geert Uytterhoeven, George Stark, Jiapeng Chong, Krzysztof Kozlowski, Laurent Pinchart, Liao Chen, Liu Ying, Rob Herring and Wolfram Sang for code contributions and reviews and to Lee Jones for preparing the above mentioned immutable branch. -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEP4GsaTp6HlmJrf7Tj4D7WH0S/k4FAmboM3AACgkQj4D7WH0S /k6IzQgAj+3B4F4UKPPI8jcQqRQGOWfjA365nIQmr1oeFYSGDILv4btU1TNV1MfH WLXMRXLQb4dng21J8IwIJ/qyndL+GjRj3KWxLHJa3+/gxf8YuGwWJlNjlxtrGXM/ 3JQ/aWqfgCf4KTRG3MoCTKc5fxtbHHWZ71kGdi6cchk1HggyBUH/7g85h/VkhCuc JpOC7CvDVmzTkTIltCbiVJQ4xO3zmsV2WgnsWUzN+41PUjqJmMLmhKjI6UdAYWlI B3qgCMXik153oYgaIw/BMtxFWa9e2ZxZ6hV+gx4tVQWbOtBPUxEqHpX2dt1fp5+h 7PQoKVWJycykdxmlOSGnjOl3RHVX5A== =VjPD -----END PGP SIGNATURE----- Merge tag 'pwm/for-6.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/ukleinek/linux Pull pwm updates from Uwe Kleine-König: "This contains some cleanups to the core and some mostly minor updates to a bunch of drivers and device tree bindings.

* MTD changes
No particularly important patchset this cycle, but we have a few usual
improvements: like using a better/more recent helper or checking a
return value.
* Raw NAND changes
The use of for_each_child_of_node_scoped() has been spread into the
subsystem drivers. Aside from that, a couple of exit path have been
fixed (mtk, denali), the TI GPMC bindings have been enhanced to comply
with up-to-date partition descriptions and as always there is a load of
small and misc fixes.
* SPI-NAND changes
The most impacting series this cycle is bringing support for continuous
reads in the SPI-NAND subsystem. This is a feature already merged in the
raw NAND subsystem which allows optimizing the internal fetch times in
the chip while reading sequential pages within an eraseblock. For now
only Macronix NANDs benefit from this feature. While we are talking
about Macronix, some of their chip need an explicit action for selecting
a different plane, and support for it has also been brought.
The bitflip threshold has also been set to the same arbitrary level as
in the raw NAND subsystem to optimize wear leveling decisions, and
finally support for a new Winbond chip has been added.
* SPI NOR changes
Notable changes:
- Add Write Protect support for N25Q064A.
- New flash support for Zetta ZD25Q128C and Spansion S28HS256T.
- Fix a NULL dereference in probe path for flashes without a name. The
probe path tries to access the name without checking its existence
first. S28HS256T is the first flash to define its entry without a
name, uncovering this issue.

Pull MTD updates from Miquel Raynal:
"MTD changes:
- No particularly important patchset this cycle, but we have a few
usual improvements: like using a better/more recent helper or
checking a return value.
Raw NAND changes:
- The use of for_each_child_of_node_scoped() has been spread into the
subsystem drivers
- a couple of exit path have been fixed (mtk, denali)
- TI GPMC bindings have been enhanced to comply with up-to-date
partition descriptions
- a load of small and misc fixes
SPI-NAND changes:
- The most impacting series this cycle is bringing support for
continuous reads in the SPI-NAND subsystem.
This is a feature already merged in the raw NAND subsystem which
allows optimizing the internal fetch times in the chip while
reading sequential pages within an eraseblock.
For now only Macronix NANDs benefit from this feature. While we are
talking about Macronix, some of their chip need an explicit action
for selecting a different plane, and support for it has also been
brought.
- The bitflip threshold has also been set to the same arbitrary level
as in the raw NAND subsystem to optimize wear leveling decisions
- Add upport for a new Winbond chip
SPI NOR changes:
- Add Write Protect support for N25Q064A.
- New flash support for Zetta ZD25Q128C and Spansion S28HS256T.
- Fix a NULL dereference in probe path for flashes without a name.
The probe path tries to access the name without checking its
existence first. S28HS256T is the first flash to define its entry
without a name, uncovering this issue"

This pull request contains documentation updates from Andrea Parri and Akira Yokosawa. Also, there is now an lkmm@lists.linux.dev, and Boqun Feng's update adds this to the LKMM MAINTAINERS entry. Not included in this pull request are a couple of more commits from Puranjay Mohan adding more atomic operations to LKMM, but these await a herdtools7 release that includes tool-side support for this functionality. With luck, I will send a separate pull request for these later in the merge window. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEbK7UrM+RBIrCoViJnr8S83LZ+4wFAmblNc0THHBhdWxtY2tA a2VybmVsLm9yZwAKCRCevxLzctn7jMvOEACFyAA6YLyke0322jofnmuRG/RL16IX SmGL5InhhvOYbMEqFQ3PJCb2hjJkOJx0omw5sbV2LPVD77h+pmIFQ6owMO2xkN1T vCZulz1Nn/9+qr4l7gPDERokCl7bpH7IoCD3AXLni/nZjRKQ1xysCI9RqgyGtTOn AuHuDPbYsB7KC3WqLwedIsGgUatmCm8qM1DzpvxzU6R5/nMKmxlaQ+87bXEz3L92 QUqHpw1oDr0M4WaFpum/SAGKV2ZF9lbHzvPnH1I0qu0DEYvzV70cilaT2rKgpMGm OQMA97TIgpXKIsmdO7rHCHaSEADRCC4/qznom2qkGZ1FAaR+63hcvns7hiLZNKbj l60lG0g2YpRXnSj4HE1xaQUKmmEbdyK34QRHDFzlBA3CCAOINnCin9OE5lySgXHm XVcUGk40nlCugIXh2tOg60voScGqzJry9P3wOCNzb5oMGbDdB5kPEHaNsDst1YF+ S5htzegm43EKVtUiU/p2f6PT1J/FY54PD1guTpbtcIdoPzl5YK29yJM23TBqHXzr ZQcLgHNzFzfd1scLTqpAYuSf/C8ivkWt1U3QbzViCbgEejqbybAKVQi+0WX5PJHG 8YCnmmbDestyaG/Kenix97zR9AJIfAbUqR2uhMJmhBMXoryfIAZB64vRizsmxEPl FWnxDZdZ2t+g+g== =quz0 -----END PGP SIGNATURE----- Merge tag 'lkmm.2024.09.14b' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu Pull memory model doc updates from Paul McKenney: "lkmm: Add documentation and mailing list This contains documentation updates from Andrea Parri and Akira Yokosawa.

rcu_node lock.
srcu.12.08.24a: Make SRCU gp seq wrap-around faster; add KCSAN checks
for concurrent updates to ->srcu_n_exp_nodelay and
->reschedule_count which are used in heuristics governing
auto-expediting of normal SRCU grace periods and
grace-period-state-machine delays; mark idle SRCU-barrier
callbacks to help identify stuck SRCU-barrier callback.
rcu.tasks.14.08.24a: Remove RCU Tasks Rude asynchronous APIs as they

memory to avoid double-free bugs on modprobe failures; maintain
per-task instead of per-CPU callbacks count to avoid any issues
with migration of either tasks or callbacks; constify struct
ref_scale_ops.
fixes.12.08.24a: Use system_unbound_wq for kfree_rcu work to avoid
disturbing isolated CPUs.
misc.11.08.24a: Warn on unexpected rcu_state.srs_done_tail state;

Merge tag 'kvm-x86-vmx-6.12' of https://github.com/kvm-x86/linux into HEAD
KVM VMX changes for 6.12: - Set FINAL/PAGE in the page fault error code for EPT Violations if and only if the GVA is valid. If the GVA is NOT valid, there is no guest-side page table walk and so stuffing paging related metadata is nonsensical. - Fix a bug where KVM would incorrectly synthesize a nested VM-Exit instead of emulating posted interrupt delivery to L2. - Add a lockdep assertion to detect unsafe accesses of vmcs12 structures. - Harden eVMCS loading against an impossible NULL pointer deref (really truly should be impossible). - Minor SGX fix and a cleanup. |

Merge branch 'kvm-redo-enable-virt' into HEAD
Register KVM's cpuhp and syscore callbacks when enabling virtualization in hardware, as the sole purpose of said callbacks is to disable and re-enable virtualization as needed. The primary motivation for this series is to simplify dealing with enabling virtualization for Intel's TDX, which needs to enable virtualization when kvm-intel.ko is loaded, i.e. long before the first VM is created. That said, this is a nice cleanup on its own. By registering the callbacks on-demand, the callbacks themselves don't need to check kvm_usage_count, because their very existence implies a non-zero count. Patch 1 (re)adds a dedicated lock for kvm_usage_count. This avoids a lock ordering issue between cpus_read_lock() and kvm_lock. The lock ordering issue still exist in very rare cases, and will be fixed for good by switching vm_list to an (S)RCU-protected list. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> |

Merge branch 'kvm-memslot-zap-quirk' into HEAD
Today whenever a memslot is moved or deleted, KVM invalidates the entire page tables and generates fresh ones based on the new memslot layout. This behavior traditionally was kept because of a bug which was never fully investigated and caused VM instability with assigned GeForce GPUs. It generally does not have a huge overhead, because the old MMU is able to reuse cached page tables and the new one is more scalabale and can resolve EPT violations/nested page faults in parallel, but it has worse performance if the guest frequently deletes and adds small memslots, and it's entirely not viable for TDX. This is because TDX requires re-accepting of private pages after page dropping. For non-TDX VMs, this series therefore introduces the KVM_X86_QUIRK_SLOT_ZAP_ALL quirk, enabling users to control the behavior of memslot zapping when a memslot is moved/deleted. The quirk is turned on by default, leading to the zapping of all SPTEs when a memslot is moved/deleted; users however have the option to turn off the quirk, which limits the zapping only to those SPTEs hat lie within the range of memslot being moved/deleted.

sound updates for 6.12-rc1
A fairly big update at this time, both in core and driver sides.
The core received rewrites in PCM buffer allocation handling and
locking optimizations, PCM rate updates followed by lots of cleanups.
In ASoC side, the legacy Intel drivers have been deprecated by AVS
drivers which leaded to the significant amount of code reduction.
SoundWire driver updates and other cleanups contributed more code
reduction, too.
USB-audio driver received a large cleanup of its big quirk table, and
the old snd_print*() API usages in many legacy drivers are replaced
with the standard print API.
Here are some highlights:
Core:
- More optimized locking in ALSA control code
- Rewrites of memalloc helpers for better DMA API usage
- Drop of obsoleted vmalloc PCM buffer helper API
- Continued MIDI2 UMP updates
- Support of a new user-space driven timer instance
- Update for more PCM support rates and cleanups
- Xrun counter report in the proc files
ASoC:
- Continued simplification and cleanup works for ASoC
- Extensive cleanups and refactoring of the Soundwire drivers
- Removal of Intel machine support obsoleted by the AVS driver
- Lots of DT schema conversions
- Machine support for many AMD and Intel x86 platforms
- Support for AMD ACP 7.1, Mediatek MT6367 and MT8365, Realtek RTL1320
SoundWire and rev C, and Texas Instruments TAS2563
USB-audio:
- Add support of multiple control interfaces
- A large rewrite of quirk table with macros
- Support for RME Digiface USB
HD-audio:
- Cleanup of quirk code for Samsung Galaxy laptops
- Clean up of detection of Cirrus codecs
- C-Media CM9825 HD-audio codec support
Others:
- Rewrites to standard print API in a lot of legacy drivers

soc: driver updates for 6.12
The driver updates seem larger this time around, with changes
is many of the SoC specific drivers, both the custom drivers/soc
ones and the closely related subsystems (memory, bus, firmware,
reset, ...).
The at91 platform gains support for sam9x7 chips in the soc and
power management code. This is the latest variant of one of the
oldest still supported SoC families, using the ARM9 (ARMv5) core.
As usual, the qualcomm snapdragon platform gets a ton of updates in many
of their drivers to add more features and additional SoC support. Most
of these are somewhat firmware related as the platform has a number of
firmware based interfaces to the kernel. A notable addition here is the
inclusion of trace events to two of these drivers.
Herve Codina and Christophe Leroy are now sending updates for
drivers/soc/fsl/ code through the SoC tree, this contains both PowerPC
and Arm specific platforms and has previously been problematic to
maintain. The first update here contains support for newer PowerPC
variants and some cleanups.
The turris mox firmware driver has a number of updates, mostly cleanups.
The Arm SCMI firmware driver gets a major rework to modularize
the existing code into separately loadable drivers for the various
transports, the addition of custom NXP i.MX9 interfaces and a
number of smaller updates.
The Arm FF-A firmware driver gets a feature update to support
the v1.2 version of the specification.
The reset controller drivers have some smaller cleanups and a newly
added driver for the Intel/Mobileye EyeQ5/EyeQ6 MIPS SoCs.
The memory controller drivers get some cleanups and refactoring
for Tegra, TI, Freescale/NXP and a couple more platforms.
Finally there are lots of minor updates to firmware (raspberry pi,
tegra, imx), bus (sunxi, omap, tegra) and soc (rockchips, tegra, amlogic,
mediatek) drivers and their DT bindings.

soc: devicetree updates for 6.12
New SoC support for Broadcom bcm2712 (Raspberry Pi 5) and Renesas
R9A09G057 (RZ/V2H(P)) and Qualcomm Snapdragon 414 (MSM8929), all three
of these are variants of already supported chips, in particular the last
one is almost identical to MSM8939.
Lots of updates to Mediatek, ASpeed, Rockchips, Amlogic, Qualcomm,

The added Qualcomm platform support once again dominates the changes,
with seven phones and three laptops getting added in addition to
many new features on existing machines. The Snapdragon X1E support
specifically keeps improving.
The other new machines are:
- eight new machines using various 64-bit Rockchips SoCs, both
on the consumer/gaming side and developer boards
- three industrial boards with 64-bit i.MX, which is a very
low number for them.
- four more servers using a 32-bit Speed BMC

spi: Updates for v6.12
This is quite a quiet release for sPI. The one new core feature here is
support for configuring the state of the MOSI pin when the bus is idle,
there are some devices which are very fragile in this regard even when
the chip select signal is not asserted. Otherwise we have some new
driver support, a bunch of small fixes and some general cleanup work.
- Support for configuring the state of the MOSI pin when the the bus is
idle.
- Add the Elgin JG0309-01 in spidev.
- Support for Marvell xSPI, Mediatek MTK7981, Microchip PIC64GX,
NXP i.MX8ULP, and Rockchip RK3576 controllers.
I also accidentally pulled in an IIO DT bindings update due to a typo
when applying the MOSI idle state patches.

regulator: Updates for v6.12
This release is almost all cleanup work of various kinds, while the
diffstat for the core is quite large this is almost all cleanups and
documentation improvments with some small fixes rather than any new
feature work. We do have support for a couple of new devices but these
are small additions to existing drivers rather than new drivers.
- Removal of the SM5703 driver which does not have it's dependencies
available.
- Support for Allwinner AXP717, and Qualcomm WCN6855.
The Allwinner support shares some commits with the MFD tree.

Updates for timers and timekeeping:
- Core:
- Overhaul of posix-timers in preparation of removing the
workaround for periodic timers which have signal delivery
ignored.
- Remove the historical extra jiffie in msleep()
msleep() adds an extra jiffie to the timeout value to ensure
minimal sleep time. The timer wheel ensures minimal sleep
time since the large rewrite to a non-cascading wheel, but the
extra jiffie in msleep() remained unnoticed. Remove it.
- Make the timer slack handling correct for realtime tasks.
The procfs interface is inconsistent and does neither reflect
reality nor conforms to the man page. Show the correct 0 slack
for real time tasks and enforce it at the core level instead of
having inconsistent individual checks in various timer setup
functions.
- The usual set of updates and enhancements all over the place.
- Drivers:
- Allow the ACPI PM timer to be turned off during suspend
- No new drivers
- The usual updates and enhancements in various drivers

Updates for the interrupt subsystem:
- Core:
- Remove a global lock in the affinity setting code
The lock protects a cpumask for intermediate results and the lock
causes a bottleneck on simultaneous start of multiple virtual
machines. Replace the lock and the static cpumask with a per CPU
cpumask which is nicely serialized by raw spinlock held when
executing this code.
- Provide support for giving a suffix to interrupt domain names.
That's required to support devices with subfunctions so that the
domain names are distinct even if they originate from the same
device node.
- The usual set of cleanups and enhancements all over the place
- Drivers:
- Support for longarch AVEC interrupt chip
- Refurbishment of the Armada driver so it can be extended for new
variants.
- The usual set of cleanups and enhancements all over the place

Those callbacks which haven't been converted were left as-is due to the general ugliness of the changes required to support the static call conversion; we can revisit those callbacks at a future date. - Add the Integrity Policy Enforcement (IPE) LSM This adds a new LSM, Integrity Policy Enforcement (IPE). There is plenty of documentation about IPE in this patches, so I'll refrain from going into too much detail here, but the basic motivation behind IPE is to provide a mechanism such that administrators can restrict execution to only those binaries which come from integrity protected storage, e.g. a dm-verity protected filesystem. You will notice that IPE requires additional LSM hooks in the initramfs, dm-verity, and fs-verity code, with the associated patches carrying ACK/review tags from the associated maintainers. We couldn't find an obvious maintainer for the initramfs code, but the IPE patchset has been widely posted over several years. Both Deven Bowers and Fan Wu have contributed to IPE's development over the past several years, with Fan Wu agreeing to serve as the IPE maintainer moving forward. Once IPE is accepted into your tree, I'll start working with Fan to ensure he has the necessary accounts, keys, etc. so that he can start submitting IPE pull requests to you directly during the next merge window. - Move the lifecycle management of the LSM blobs to the LSM framework Management of the LSM blobs (the LSM state buffers attached to various kernel structs, typically via a void pointer named "security" or similar) has been mixed, some blobs were allocated/managed by individual LSMs, others were managed by the LSM framework itself. Starting with this pull we move management of all the LSM blobs, minus the XFRM blob, into the framework itself, improving consistency across LSMs, and reducing the amount of duplicated code across LSMs. Due to some additional work required to migrate the XFRM blob, it has been left as a todo item for a later date; from a practical standpoint this omission should have little impact as only SELinux provides a XFRM LSM implementation. - Fix problems with the LSM's handling of F_SETOWN The LSM hook for the fcntl(F_SETOWN) operation had a couple of problems: it was racy with itself, and it was disconnected from the associated DAC related logic in such a way that the LSM state could be updated in cases where the DAC state would not. We fix both of these problems by moving the security_file_set_fowner() hook into the same section of code where the DAC attributes are updated. Not only does this resolve the DAC/LSM synchronization issue, but as that code block is protected by a lock, it also resolve the race condition. - Fix potential problems with the security_inode_free() LSM hook Due to use of RCU to protect inodes and the placement of the LSM hook associated with freeing the inode, there is a bit of a challenge when it comes to managing any LSM state associated with an inode. The VFS folks are not open to relocating the LSM hook so we have to get creative when it comes to releasing an inode's LSM state. Traditionally we have used a single LSM callback within the hook that is triggered when the inode is "marked for death", but not actually released due to RCU. Unfortunately, this causes problems for LSMs which want to take an action when the inode's associated LSM state is actually released; so we add an additional LSM callback, inode_free_security_rcu(), that is called when the inode's LSM state is released in the RCU free callback. - Refactor two LSM hooks to better fit the LSM return value patterns The vast majority of the LSM hooks follow the "return 0 on success, negative values on failure" pattern, however, there are a small handful that have unique return value behaviors which has caused confusion in the past and makes it difficult for the BPF verifier to properly vet BPF LSM programs. This includes patches to convert two of these"special" LSM hooks to the common 0/-ERRNO pattern. - Various cleanups and improvements A handful of patches to remove redundant code, better leverage the IS_ERR_OR_NULL() helper, add missing "static" markings, and do some minor style fixups. * tag 'lsm-pr-20240911' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm: (40 commits) security: Update file_set_fowner documentation fs: Fix file_set_fowner LSM hook inconsistencies lsm: Use IS_ERR_OR_NULL() helper function lsm: remove LSM_COUNT and LSM_CONFIG_COUNT ipe: Remove duplicated include in ipe.c lsm: replace indirect LSM hook calls with static calls lsm: count the LSMs enabled at compile time kernel: Add helper macros for loop unrolling init/main.c: Initialize early LSMs after arch code, static keys and calls.

Pull netfs updates from Christian Brauner:
"This contains the work to improve read/write performance for the new
netfs library.
The main performance enhancing changes are:
- Define a structure, struct folio_queue, and a new iterator type,
ITER_FOLIOQ, to hold a buffer as a replacement for ITER_XARRAY. See
that patch for questions about naming and form.
ITER_FOLIOQ is provided as a replacement for ITER_XARRAY. The
problem with an xarray is that accessing it requires the use of a
lock (typically the RCU read lock) - and this means that we can't
supply iterate_and_advance() with a step function that might sleep
(crypto for example) without having to drop the lock between pages.
ITER_FOLIOQ is the iterator for a chain of folio_queue structs,
where each folio_queue holds a small list of folios. A folio_queue
struct is a simpler structure than xarray and is not subject to
concurrent manipulation by the VM. folio_queue is used rather than
a bvec[] as it can form lists of indefinite size, adding to one end
and removing from the other on the fly.
- Provide a copy_folio_from_iter() wrapper.
- Make cifs RDMA support ITER_FOLIOQ.
- Use folio queues in the write-side helpers instead of xarrays.
- Add a function to reset the iterator in a subrequest.
- Simplify the write-side helpers to use sheaves to skip gaps rather
than trying to work out where gaps are.
- In afs, make the read subrequests asynchronous, putting them into
work items to allow the next patch to do progressive
unlocking/reading.
- Overhaul the read-side helpers to improve performance.
- Fix the caching of a partial block at the end of a file.
- Allow a store to be cancelled.
Then some changes for cifs to make it use folio queues instead of
xarrays for crypto bufferage:
- Use raw iteration functions rather than manually coding iteration
when hashing data.
- Switch to using folio_queue for crypto buffers.
- Remove the xarray bits.
Make some adjustments to the /proc/fs/netfs/stats file such that:
- All the netfs stats lines begin 'Netfs:' but change this to
something a bit more useful.
- Add a couple of stats counters to track the numbers of skips and
waits on the per-inode writeback serialisation lock to make it
easier to check for this as a source of performance loss.
Miscellaneous work:
- Ensure that the sb_writers lock is taken around
vfs_{set,remove}xattr() in the cachefiles code.
- Reduce the number of conditional branches in netfs_perform_write().
- Move the CIFS_INO_MODIFIED_ATTR flag to the netfs_inode struct and
remove cifs_post_modify().
- Move the max_len/max_nr_segs members from netfs_io_subrequest to
netfs_io_request as they're only needed for one subreq at a time.
- Add an 'unknown' source value for tracing purposes.
- Remove NETFS_COPY_TO_CACHE as it's no longer used.
- Set the request work function up front at allocation time.
- Use bh-disabling spinlocks for rreq->lock as cachefiles completion
may be run from block-filesystem DIO completion in softirq context.
- Remove fs/netfs/io.c"

"This contains the following changes for procfs:
- Add config options and parameters to block forcing memory writes.
This adds a Kconfig option and boot param to allow removing the
FOLL_FORCE flag from /proc/<pid>/mem write calls as this can be
used in various attacks.
The traditional forcing behavior is kept as default because it can
break GDB and some other use cases.
This is the simpler version that you had requested.
- Restrict overmounting of ephemeral entities.
It is currently possible to mount on top of various ephemeral
entities in procfs. This specifically includes magic links. To
recap, magic links are links of the form /proc/<pid>/fd/<nr>. They
serve as references to a target file and during path lookup they
cause a jump to the target path. Such magic links disappear if the
corresponding file descriptor is closed.
Currently it is possible to overmount such magic links. This is
mostly interesting for an attacker that wants to somehow trick a
process into e.g., reopening something that it didn't intend to
reopen or to hide a malicious file descriptor.
But also it risks leaking mounts for long-running processes. When
overmounting a magic link like above, the mount will not be
detached when the file descriptor is closed. Only the target
mountpoint will disappear. Which has the consequence of making it
impossible to unmount that mount afterwards. So the mount will
stick around until the process exits and the /proc/<pid>/ directory
is cleaned up during proc_flush_pid() when the dentries are pruned
and invalidated.
That in turn means it's possible for a program to accidentally leak
mounts and it's also possible to make a task leak mounts without
it's knowledge if the attacker just keeps overmounting things under
/proc/<pid>/fd/<nr>.
Disallow overmounting of such ephemeral entities.
- Cleanup the readdir method naming in some procfs file operations.
- Replace kmalloc() and strcpy() with a simple kmemdup() call"

Pull misc vfs updates from Christian Brauner:
"This contains the usual pile of misc updates:
Features:
- Add F_CREATED_QUERY fcntl() that allows userspace to query whether
a file was actually created. Often userspace wants to know whether
an O_CREATE request did actually create a file without using
O_EXCL. The current logic is that to first attempts to open the
file without O_CREAT | O_EXCL and if ENOENT is returned userspace
tries again with both flags. If that succeeds all is well. If it
now reports EEXIST it retries.
That works fairly well but some corner cases make this more
involved. If this operates on a dangling symlink the first openat()
without O_CREAT | O_EXCL will return ENOENT but the second openat()
with O_CREAT | O_EXCL will fail with EEXIST.
The reason is that openat() without O_CREAT | O_EXCL follows the
symlink while O_CREAT | O_EXCL doesn't for security reasons. So
it's not something we can really change unless we add an explicit
opt-in via O_FOLLOW which seems really ugly.
All available workarounds are really nasty (fanotify, bpf lsm etc)
so add a simple fcntl().
- Try an opportunistic lookup for O_CREAT. Today, when opening a file
we'll typically do a fast lookup, but if O_CREAT is set, the kernel
always takes the exclusive inode lock. This was likely done with
the expectation that O_CREAT means that we always expect to do the
create, but that's often not the case. Many programs set O_CREAT
even in scenarios where the file already exists (see related
F_CREATED_QUERY patch motivation above).
The series contained in the pr rearranges the pathwalk-for-open
code to also attempt a fast_lookup in certain O_CREAT cases. If a
positive dentry is found, the inode_lock can be avoided altogether
and it can stay in rcuwalk mode for the last step_into.
- Expose the 64 bit mount id via name_to_handle_at()
Now that we provide a unique 64-bit mount ID interface in statx(2),
we can now provide a race-free way for name_to_handle_at(2) to
provide a file handle and corresponding mount without needing to
worry about racing with /proc/mountinfo parsing or having to open a
file just to do statx(2).
While this is not necessary if you are using AT_EMPTY_PATH and
don't care about an extra statx(2) call, users that pass full paths
into name_to_handle_at(2) need to know which mount the file handle
comes from (to make sure they don't try to open_by_handle_at a file
handle from a different filesystem) and switching to AT_EMPTY_PATH
would require allocating a file for every name_to_handle_at(2) call
- Add a per dentry expire timeout to autofs
There are two fairly well known automounter map formats, the autofs
format and the amd format (more or less System V and Berkley).
Some time ago Linux autofs added an amd map format parser that
implemented a fair amount of the amd functionality. This was done
within the autofs infrastructure and some functionality wasn't
implemented because it either didn't make sense or required extra
kernel changes. The idea was to restrict changes to be within the
existing autofs functionality as much as possible and leave changes
with a wider scope to be considered later.
One of these changes is implementing the amd options:
1) "unmount", expire this mount according to a timeout (same as
the current autofs default).
2) "nounmount", don't expire this mount (same as setting the
autofs timeout to 0 except only for this specific mount) .
3) "utimeout=<seconds>", expire this mount using the specified
timeout (again same as setting the autofs timeout but only for
this mount)
To implement these options per-dentry expire timeouts need to be
implemented for autofs indirect mounts. This is because all map
keys (mounts) for autofs indirect mounts use an expire timeout
stored in the autofs mount super block info. structure and all
indirect mounts use the same expire timeout.
Fixes:
- Fix missing fput for FSCONFIG_SET_FD in autofs
- Use param->file for FSCONFIG_SET_FD in coda
- Delete the 'fs/netfs' proc subtreee when netfs module exits
- Make sure that struct uid_gid_map fits into a single cacheline
- Don't flush in-flight wb switches for superblocks without cgroup
writeback
- Correcting the idmapping mount example in the idmapping

- Handle OOM on mnt_warn_timestamp_expiry()
- Fix some spelling in the iomap design documentation
- Fix typo in procfs comment
- Fix typo in fs/namespace.c comment
Cleanups:
- Add the VFS git tree to the MAINTAINERS file

bit in struct file bringing us to 5 free f_mode bits
- Remove the __I_DIO_WAKEUP bit from i_state flags as we can simplify

"These mostly continue to rework the thermal core and the thermal zone
driver interface to make the code more straightforward and reduce
bloat
The most significant piece of this work is a change of the code
related to binding cooling devices to thermal zones which, among other
things, replaces two previously existing thermal zone operations with
one allowing driver implementations to be much simpler
There is also a new thermal core testing module allowing mock thermal
zones to be created and controlled via debugfs in order to exercise
the thermal core functionality. It is expected to be used for
implementing thermal core self tests in the future

Pull power management updates from Rafael Wysocki:
"By the number of new lines of code, the most visible change here is
the addition of hybrid CPU capacity scaling support to the
intel_pstate driver. Next are the amd-pstate driver changes related to
the calculation of the AMD boost numerator and preferred core
detection.
As far as new hardware support is concerned, the intel_idle driver
will now handle Granite Rapids Xeon processors natively, the
intel_rapl power capping driver will recognize family 1Ah of AMD
processors and Intel ArrowLake-U chipos, and intel_pstate will handle
Granite Rapids and Sierra Forest chips in the out-of-band (OOB) mode.
Apart from the above, there is a usual collection of assorted fixes
and code cleanups in many places and there are tooling updates.

Merge patch series "Svvptc extension to remove preventive sfence.vma"
Alexandre Ghiti <alexghiti@rivosinc.com> says: In RISC-V, after a new mapping is established, a sfence.vma needs to be emitted for different reasons: - if the uarch caches invalid entries, we need to invalidate it otherwise we would trap on this invalid entry, - if the uarch does not cache invalid entries, a reordered access could fail to see the new mapping and then trap (sfence.vma acts as a fence). We can actually avoid emitting those (mostly) useless and costly sfence.vma by handling the traps instead: - for new kernel mappings: only vmalloc mappings need to be taken care of, other new mapping are rare and already emit the required sfence.vma if needed. That must be achieved very early in the exception path as explained in patch 3, and this also fixes our fragile way of dealing with vmalloc faults. - for new user mappings: Svvptc makes update_mmu_cache() a no-op but we can take some gratuitous page faults (which are very unlikely though). Patch 1 and 2 introduce Svvptc extension probing. On our uarch that does not cache invalid entries and a 6.5 kernel, the gains are measurable: * Kernel boot: 6% * ltp - mmapstress01: 8% * lmbench - lat_pagefault: 20% * lmbench - lat_mmap: 5% Here are the corresponding numbers of sfence.vma emitted: * Ubuntu boot to login: Before: ~630k sfence.vma After: ~200k sfence.vma * ltp - mmapstress01 Before: ~45k After: ~6.3k * lmbench - lat_pagefault Before: ~665k After: 832 (!) * lmbench - lat_mmap Before: ~546k After: 718 (!)

ASoC: Updates for v6.12
This is a very large set of changes, almost all in drivers rather than
the core. Even with the addition of several quite large drivers the
overall diffstat is negative thanks to the removal of some old Intel
board support which has been obsoleted by the AVS driver, helped a bit
by some factoring out into helpers (especially around the Soundwire
machine drivers for x86).
Highlights include:
- More simplifications and cleanups throughout the subsystem from
Morimoto-san.
- Extensive cleanups and refactoring of the Soundwire drivers to make
better use of helpers.
- Removal of Intel machine support obsoleted by the AVS driver.
- Lots of DT schema conversions.
- Machine support for many AMD and Intel x86 platforms.
- Support for AMD ACP 7.1, Mediatek MT6367 and MT8365, Realtek RTL1320
SoundWire and rev C, and Texas Instruments TAS2563

docs/memory-barriers.txt: Remove left-over references to "CACHE COHERENCY"
Commit 8ca924aeb4f2 ("Documentation/barriers: Remove references to
[smp_]read_barrier_depends()") removed the entire section of "CACHE
COHERENCY", without getting rid of its traces.
Remove them.
