erofs: unify lcn as u64 for 32-bit platforms
erofs: fix offset truncation when shifting pgoff on 32-bit platforms
erofs: fix the out-of-bounds nameoff handling for trailing dirents
of effort from Brian Masney. Now the only option is to use determine_rate(),
which is good because that takes a struct argument instead of just a couple
unsigned longs, allowing us to easily modify the way we determine and set rates

Beyond that core framework change we've got the typical pile of new SoC clk
driver additions, fixes for clk data and/or adding missing clks because the
consumer driver using those clks wasn't ready, etc. The usual suspects are all
here: Qualcomm, Samsung, Mediatek, and Rockchip along with some newcomers
making RISC-V SoCs like ESWIN's eic700 and Tenstorrent's Atlantis. The clk
driver side of this looks pretty normal.
Core:
- Remove the round_rate() clk op (yay!)
New Drivers:
- ESWIN eic700 SoC clk support
- Econet EN751221 SoC clock/reset support
- Global TCSR, RPMh, and display clock controller support for
the Qualcomm Eliza platform
- TCSR, the multiple global, and the RPMh clock controller

If shrink_dcache_tree() finds a dentry in the middle of being killed
by another thread, it has to wait until the victim finishes dying,
gets detached from the tree and ceases to pin its parent.
The way we used to deal with that amounted to busy-wait; unfortunately,
it's not just inefficient but can lead to reliably reproducible hard
livelocks.
Solved by having shrink_dentry_tree() attach a completion to such dentry,
with dentry_unlist() calling complete() on all objects attached to it.
With a bit of care it can be done without growing struct dentry or adding
overhead in normal case.

As sashiko reported [1], `lcn` was typed as `unsigned long` (or
`unsigned int` sometimes), which is only 32 bits wide on 32-bit
platforms, which causes `(lcn << lclusterbits)` to be truncated
at 4 GiB.
In order to consolidate the logic, just use `u64` consistently
around the codebase.

On 32-bit platforms, pgoff_t is 32 bits wide, so left-shifting
large arbitrary pgoff_t values by PAGE_SHIFT performs 32-bit arithmetic
and silently truncates the result for pages beyond the 4 GiB boundary.
Cast the page index to loff_t before shifting to produce a correct
64-bit byte offset.

Currently we already have boundary-checks for nameoffs, but the trailing
dirents are special since the namelens are calculated with strnlen()
with unchecked nameoffs.
If a crafted EROFS has a trailing dirent with nameoff >= maxsize,
maxsize - nameoff can underflow, causing strnlen() to read past the
directory block.
nameoff0 should also be verified to be a multiple of
`sizeof(struct erofs_dirent)` as well [1].

requiring IPIs during TLB maintenance if a process is running in user
space with SME enabled.
The hardware acknowledges the DVMSync messages before completing
in-flight SME accesses, with security implications. The workaround
makes use of the mm_cpumask() to track the cores that need
interrupting (arm64 hasn't used this mask before).
The rest are fixes for MPAM, CCA and generated header that turned up
during the merging window or shortly before.
Summary:
Core features:
- Add workaround for C1-Pro erratum 4193714 - early CME (SME unit)
DVMSync acknowledgement. The fix consists of sending IPIs on TLB
maintenance to those CPUs running in user space with SME enabled
- Include kernel-hwcap.h in list of generated files (missed in a
recent commit generating the KERNEL_HWCAP_* macros)
CCA:
- Fix RSI_INCOMPLETE error check in arm-cca-guest
MPAM:
- Fix an unmount->remount problem with the CDP emulation,
uninitialised variable and checker warnings"

Merge tag 'sh-for-v7.1-tag1' of git://git.kernel.org/pub/scm/linux/kernel/git/glaubitz/sh-linux
Pull sh updates from John Paul Adrian Glaubitz:
"Two patches from Thomas Zimmermann, one by Tim Bird and one by Thomas
Weißschuh.
The first patch by Thomas Zimmermann adds a missing include in dac.h
for SH-3 which became necessary after 243ce64b2b ("backlight: Do not
include <linux/fb.h> in header file") which made __raw_readb() and
__raw_writeb() inaccessible in dac.h.
Thomas' second patch drops CONFIG_FIRMWARE_EDID for SH as it depends
on X86 or EFI_GENERIC_STUB which are not defined on SH for obvious
reasons.
The patch by Tim Bird fixes just a small typo in two SPDX ID lines
which he stumbled over by accident.
And, least but not last, the patch by Thomas Weißschuh removes the
CONFIG_VSYSCALL reference from UAPI. This was necessary as the
definition of AT_SYSINFO_EHDR was gated between CONFIG_VSYSCALL to
avoid a default gate VMA to be created. However that default gate VMA
was removed entirely in commit a6c19dfe39 (arm64,ia64,ppc,s390,
sh,tile,um,x86,mm: remove default gate area)"

The set of eCryptfs changes for the 7.1-rc1 merge window consists of:
- A fix to avoid unnecessary eCryptfs inode timestamp truncation by
re-using the lower filesystem's time granularity
- Various small code cleanups
- Reorganization of the setattr hook's handling of inode resizing to
improve style and readability, remove an unnecessary memory allocation
when shrinking, and to support an upcoming rework of the VFS
interfaces involved in truncation
The patches have all spent time in linux-next and they do not regress
the tests in the ecryptfs-utils tree. The inode timestamp fix returns
the "setattr-flush-dirty" test to passing state.

Benjamin Coddington contributed filehandle signing to defend against
filehandle-guessing attacks. The server now appends a SipHash-2-4
MAC to each filehandle when the new "sign_fh" export option is
enabled. NFSD then verifies filehandles received from clients
against the expected MAC; mismatches return NFS error STALE.
Chuck Lever converted the entire NLMv4 server-side XDR layer from
hand-written C to xdrgen-generated code, spanning roughly thirty
patches. XDR functions are generally boilerplate code and are easy
to get wrong. The goals of this conversion are improved memory
safety, lower maintenance burden, and groundwork for eventual Rust
code generation for these functions.
Dai Ngo improved pNFS block/SCSI layout robustness with two related
changes. SCSI persistent reservation fencing is now tracked per
client and per device via an xarray, to avoid both redundant preempt
operations on devices already fenced and a potential NFSD deadlock
when all nfsd threads are waiting for a layout return.
The remaining patches deliver scalability and infrastructure
improvements. Sincere thanks to all contributors, reviewers,
testers, and bug reporters who participated in the v7.1 NFSD
development cycle.

krb5enc_dispatch_decrypt() sets req->base.complete as the skcipher
callback, which is the caller's own completion handler. When the
skcipher completes asynchronously, this signals "done" to the caller
without executing krb5enc_dispatch_decrypt_hash(), completely bypassing
the integrity verification (hash check).
Compare with the encrypt path which correctly uses
krb5enc_encrypt_done as an intermediate callback to chain into the
hash computation on async completion.
Fix by adding krb5enc_decrypt_done as an intermediate callback that
chains into krb5enc_dispatch_decrypt_hash() upon async skcipher
completion, matching the encrypt path's callback pattern.
Also fix EBUSY/EINPROGRESS handling throughout: remove
krb5enc_request_complete() which incorrectly swallowed EINPROGRESS
notifications that must be passed up to callers waiting on backlogged
requests, and add missing EBUSY checks in krb5enc_encrypt_ahash_done
for the dispatch_encrypt return value.

AF_ALG AEAD AIO requests currently use the socket-wide IV buffer during
request processing. For async requests, later socket activity can
update that shared state before the original request has fully
completed, which can lead to inconsistent IV handling.
Snapshot the IV into per-request storage when preparing the AEAD
request, so in-flight operations no longer depend on mutable socket
state.

that never got any actual hardware support (esp32), and the second try
to moving the tty ports to their own workqueues (first try was in

Otherwise it's just a small set of driver updates and some vt modifier

- The 33 patch series "Eliminate Dying Memory Cgroup" from Qi Zheng and
Muchun Song addresses the longstanding "dying memcg problem". A
situation wherein a no-longer-used memory control group will hang around
for an extended period pointlessly consuming memory. The [0/N]
changelog has a good overview of this work.

Commit d8f867fa08 ("mm/damon: add damon_ctx->min_sz_region") introduced
a bug that allows unaligned DAMON region address ranges. Commit
c80f46ac22 ("mm/damon/core: disallow non-power of two min_region_sz")
fixed it, but only for damon_commit_ctx() use case. Still, DAMON sysfs
interface can emit non-power of two min_region_sz via damon_start(). Fix
the path by adding the is_power_of_2() check on damon_start().
The issue was discovered by sashiko [1].

decay_va_pool_node() can be invoked concurrently from two paths:
__purge_vmap_area_lazy() when pools are being purged, and the shrinker via
vmap_node_shrink_scan().
However, decay_va_pool_node() is not safe to run concurrently, and the
shrinker path currently lacks serialization, leading to races and possible
leaks.
Protect decay_va_pool_node() by taking vmap_purge_lock in the shrinker
path to ensure serialization with purge users.

We can only call filemap_free_folio() if we have a reference to (or hold a
lock on) the mapping. Otherwise, we've already removed the folio from the
mapping so it no longer pins the mapping and the mapping can be removed,
causing a use-after-free when accessing mapping->a_ops.
Follow the same pattern as __remove_mapping() and load the free_folio
function pointer before dropping the lock on the mapping. That lets us
make filemap_free_folio() static as this was the only caller outside
filemap.c.

cgwb_release_workfn() calls css_put(wb->blkcg_css) and then later accesses
wb->blkcg_css again via blkcg_unpin_online(). If css_put() drops the last
reference, the blkcg can be freed asynchronously (css_free_rwork_fn ->
blkcg_css_free -> kfree) before blkcg_unpin_online() dereferences the
pointer to access blkcg->online_pin, resulting in a use-after-free:

I am seeing this crash sporadically in Meta fleet across multiple kernel
versions. A full reproducer is available at:
https://github.com/leitao/debug/blob/main/reproducers/repro_blkcg_uaf.sh
(The race window is narrow. To make it easily reproducible, inject a
msleep(100) between css_put() and blkcg_unpin_online() in
cgwb_release_workfn(). With that delay and a KASAN-enabled kernel, the
reproducer triggers the splat reliably in less than a second.)
Fix this by moving blkcg_unpin_online() before css_put(), so the
cgwb's CSS reference keeps the blkcg alive while blkcg_unpin_online()
accesses it.

The contents of a device folio can immediately change after calling
->folio_free(), as the folio may be reallocated by a driver with a
different order. Instead of touching the folio again to extract the
pgmap, use the local stack variable when calling percpu_ref_put_many().

When the throughput of a DAMOS scheme is very slow, DAMOS time quota can
make the effective size quota smaller than damon_ctx->min_region_sz. In
the case, damos_apply_scheme() will skip applying the action, because the
action is tried at region level, which requires >=min_region_sz size.
That is, the quota is effectively exceeded for the quota charge window.
Because no action will be applied, the total_charged_sz and
total_charged_ns are also not updated. damos_set_effective_quota() will
try to update the effective size quota before starting the next charge
window. However, because the total_charged_sz and total_charged_ns have
not updated, the throughput and effective size quota are also not changed.
Since effective size quota can only be decreased, other effective size
quota update factors including DAMOS quota goals and size quota cannot
make any change, either.
As a result, the scheme is unexpectedly deactivated until the user notices
and mitigates the situation. The users can mitigate this situation by
changing the time quota online or re-install the scheme. While the
mitigation is somewhat straightforward, finding the situation would be
challenging, because DAMON is not providing good observabilities for that.
Even if such observability is provided, doing the additional monitoring
and the mitigation is somewhat cumbersome and not aligned to the intention
of the time quota. The time quota was intended to help reduce the user's
administration overhead.
Fix the problem by setting time quota-modified effective size quota be at
least min_region_sz always.

The __ATTR macro is a utility that makes defining kobj_attributes easier
by stringfying the name, verifying the mode, and setting the show/store
fields in a single initializer. It takes a raw token as the first value,
rather than a string, so that __ATTR family macros like __ATTR_RW can
token-paste it for inferring the _show / _store function names.
Commit e341f9c3c8 ("mm/mempolicy: Weighted Interleave Auto-tuning") used
the __ATTR macro to define the "auto" sysfs for weighted interleave. A
few months later, commit 2fb6915fa2 ("compiler_types.h: add "auto" as a
macro for "__auto_type"") introduced a #define macro which expanded auto
into __auto_type.
This led to the "auto" token passed into __ATTR to be expanded out into
__auto_type, and the sysfs entry to be displayed as __auto_type as well.
Expand out the __ATTR macro and directly pass a string "auto" instead of
the raw token 'auto' to prevent it from being expanded out. Also bypass
the VERIFY_OCTAL_PERMISSIONS check by triple checking that 0664 is indeed
the intended permissions for this sysfs file.
Before:
$ ls /sys/kernel/mm/mempolicy/weighted_interleave
__auto_type node0
After:
$ ls /sys/kernel/mm/mempolicy/weighted_interleave/
auto node0

Add a documentation file Documentation/crypto/libcrypto.rst which
provides a high-level overview of lib/crypto/.
Also add several sub-pages which include the kernel-doc for the
algorithms that have it. This makes the existing, quite extensive
kernel-doc start being included in the HTML and PDF documentation.
Note that the intent is very much *not* that everyone has to read these
Documentation/ files. The library is intended to be straightforward and
use familiar conventions; generally it should be possible to dive right
into the kernel-doc. You shouldn't need to read a lot of documentation
to just call `sha256()`, for example, or to run the unit tests if you're
already familiar with KUnit. (This differs from the traditional crypto
API which has a larger barrier to entry.)
Nevertheless, this seems worth adding. Hopefully it is useful and makes
LWN no longer consider the library to be "meticulously undocumented".

design something new from scratch, such as SCMI.
- Broadcom BCM7038 as a pinctrl-single delegate.
- Mobileye EyeQ6Lplus OLB pin controller.
