Pull thermal control updates from Rafael Wysocki:
"The most significant part of this is a rework of thermal governors,
including a redesign of the thermal governor interface and changes to
make some of them take trip point hysteresis into account properly, as
well as some related cleanups of the thermal governors and thermal
core.
The above is based on preliminary changes refactoring thermal data
structures and moving the definitions of some of them into the thermal
core which also ensure that trip point crossing notifications will be
sent to user space via netlink and recorded in the debug statistics in
temperature order.
In addition, netlink bind/unbind notifications are added to the
thermal core and the Intel HFI driver is modified to use them to avoid
sending netlink messages until there are subscribers.
Apart from that, multiple thermal drivers are updated which includes
new hardware support (MediaTek MT8188 and MT8186, Amlogic A1 thermal
sensor, Loongson-2K2000, Lmh QCM2290), fixes, cleanups and
documentation updates, and the recently added thermal debug code is
fixed and cleaned up.

Pull sh updates from John Paul Adrian Glaubitz:
"The majority of improvements are coming from Geert Uytterhoeven who
took the time to fix a total of 30 cases of "-Wmissing-prototypes"
compiler warnings, either by adding a missing header include, defining
the missing forward declarations or making the functions in question
static.
In the case of several DMA functions, the fix was to actually just
remove them as they were added but never used. Another one of these
warnings was eliminated by removing the left-over sh5 cache handling
support, a change that was suggested by Yoshinori Sato and, finally,
the last of these warnings was fixed by guarding the function
setup_profiling_timer() with CONFIG_PROFILING.
While at it, Geert also removed two unneeded casts to kprobe_opcode_t
in the kprobes code.
Another change was contributed by Guenter Roeck to fix errors that
were reported during checksum unit tests. The fix actually reverts the
older change cadc4e1a2b4d ("sh: Handle calling csum_partial with
misaligned data") which turned to be incorrect. It remains to be
investigated whether there is a better way to handle misaligned data
in csum_partial().
A small fix contributed by Krzysztof Kozlowski drops the incorrect SPI
controller spi-max-frequency property in the device tree source file
for the J2 device platform while Uwe Kleine-König converted the
push-switch driver to have its callback function return void, a change
that is currently being applied to all drivers throughout the kernel
in order to avoid resource leaks.
Last but not least, Artur Rojek has fixed the IOPORT base address for
the Sega Dreamcast platform which allows the Linux kernel to be
successfully booted on this once popular video game console for the
first time since a long time ago"

Support for posted interrupts on bare metal
Posted interrupts is a virtualization feature which allows to inject
interrupts directly into a guest without host interaction. The VT-d
interrupt remapping hardware sets the bit which corresponds to the
interrupt vector in a vector bitmap which is either used to inject the
interrupt directly into the guest via a virtualized APIC or in case
that the guest is scheduled out provides a host side notification
interrupt which informs the host that an interrupt has been marked
pending in the bitmap.
This can be utilized on bare metal for scenarios where multiple
devices, e.g. NVME storage, raise interrupts with a high frequency. In
the default mode these interrupts are handles independently and
therefore require a full roundtrip of interrupt entry/exit.
Utilizing posted interrupts this roundtrip overhead can be avoided by
coalescing these interrupt entries to a single entry for the posted
interrupt notification. The notification interrupt then demultiplexes
the pending bits in a memory based bitmap and invokes the corresponding
device specific handlers.
Depending on the usage scenario and device utilization throughput
improvements between 10% and 130% have been measured.
As this is only relevant for high end servers with multiple device
queues per CPU attached and counterproductive for situations where
interrupts are arriving at distinct times, the functionality is opt-in
via a kernel command line parameter.

The sad state of TSC being notoriously non-sychronized for several
decades caused the kernel to grow quite rigorous sanity checks to detect
whether the TSC is valid to be used for timekeeping.
The TSC ADJUST MSR provides the offset between the initial TSC value
after hardware reset and later modifications. This allows to detect cases
where firmware tampers with the TSC and also allows to correct the
firmware induced damage by resetting the offset in a controlled way.
The universal correct rule is that the TSC ADJUST value has to be
consistent within all CPUs of a socket.
The kernel further assumes that the TSC offset should be consistent
between sockets. That's not really correct as systems with a huge number
of sockets are not architecurally guaranteed to reset the per socket TSC
base synchronously.
In case that the per socket offset is not consistent the kernel resets it
to the offset of the boot CPU and then does a synchronization check which
corrects for the inter socket delays.
That works most of the time, but it is suboptimal as the firmware has
eventually better information about the per socket offset and on sane
systems that offset should just work in the validation checks.

x86/tsc: Trust initial offset in architectural TSC-adjust MSRs
- Core code:
- Make timekeeping and VDSO time readouts resilent against math overflow:
In guest context the kernel is prone to math overflow when the host
defers the timer interrupt due to overload, malfunction or malice.
This can be mitigated by checking the clocksource delta for the
maximum deferrement which is readily available. If that value is
exceeded then the code uses a slowpath function which can handle the
multiplication overflow.
This functionality is enabled unconditionally in the kernel, but made
conditional in the VDSO code. The latter is conditional because it
allows architectures to optimize the check so it is not causing
performance regressions.
On X86 this is achieved by reworking the existing check for negative
TSC deltas as a negative delta obviously exceeds the maximum
deferrement when it is evaluated as an unsigned value. That avoids two
conditionals in the hotpath and allows to hide both the negative delta
and the large delta handling in the same slow path.
- Add an initial minimal ktime_t abstraction for Rust
- The usual boring cleanups and enhancements
- Drivers:
- Boring updates to device trees and trivial enhancements in various
drivers.

x86/mce: Dynamically size space for machine check records
Sapphire Rapids and Emerald Rapids SOCs turn out to have a bug that has
security implications.
Both of these accelerators work by the application submitting a 64 byte
command to the device; this command contains an opcode as well as the
virtual address of the return value that the device will update on
completion... and a set of opcode specific values.
In a typical scenario a ring 3 application mmaps the device file and uses
the ENQCMD or MOVDIR64 instructions (which are variations of a 64 byte
atomic write) on this mmap'd memory region to directly submit commands to a
device hardware.
The return value as specified in the command, is supposed to be 32 (or 64)
bytes aligned in memory, and generally the hardware checks and enforces
this alignment.
However in testing it has been found that there are conditions (controlled
by the submitter) where this enforcement does not happen.... which makes it
possible for the return value to span a page boundary. And this is where it
goes wrong - the accelerators will perform the virtual to physical address
lookup on the first of the two pages, but end up continue writing to the
next consecutive physical (host) page rather than the consecutive virtual
page. In addition, the device will end up in a hung state on such unaligned
write of the return value.
This patch series has the proposed software side solution consisting of 3 parts
part 1: Don't allow these two PCI devices to be assigned to VM guests
(we cannot trust a VM guest to behave correctly and not cause this condition)
part 2: Don't allow ring 3 applications to set up the mmap unless they have
CAP_SYS_RAWIO permissions. This makes it no longer possible for non-root
applications to directly submit commands to the accelerator
part 3: Add a write() method to the device so that an application can submit
its commands to the kernel driver, which performs the needed sanity checks
before submitting it to the hardware.
This switch from mmap to write is an incompatible interface change to
non-root userspace, but we have not found a way to avoid this.
All software we know of uses a small set of accessor libraries for these
accelerators, for which libqpl and libdml (on github) are the most common.
As part of the security release, updated versions of these libraries will be
released that transparently fall back to write().
Intel has assigned CVE-2024-21823 to this hardware issue.

This patch series has the proposed software side solution consisting
of three parts:
- Don't allow these two PCI devices to be assigned to VM guests (we
cannot trust a VM guest to behave correctly and not cause this
condition)
- Don't allow ring 3 applications to set up the mmap unless they have
CAP_SYS_RAWIO permissions. This makes it no longer possible for
non-root applications to directly submit commands to the
accelerator
- Add a write() method to the device so that an application can
submit its commands to the kernel driver, which performs the needed
sanity checks before submitting it to the hardware.
This switch from mmap to write is an incompatible interface change to
non-root userspace, but we have not found a way to avoid this. All
software we know of uses a small set of accessor libraries for these
accelerators, for which libqpl and libdml (on github) are the most
common. As part of the security release, updated versions of these
libraries will be released that transparently fall back to write().
Intel has assigned CVE-2024-21823 to this hardware issue"
* tag 'idxd-for-linus-may2024' of git bundle from Arjan:
dmaengine: idxd: add a write() method for applications to submit work
dmaengine: idxd: add a new security check to deal with a hardware erratum
VFIO: Add the SPR_DSA and SPR_IAX devices to the denylist
While we normally don't do such feature-enabling on 32-bit
kernels anymore, this change is small, straightforward & tested on
upstream glibc.

The most notable change is the drop of the 'alloc' in-tree fork. This
is nicely reflected in the diffstat as a ~10k lines drop. In turn, this
makes the version upgrades way simpler and smaller in the future, e.g.
the latest one in commit 56f64b370612 ("rust: upgrade to Rust 1.78.0").
More importantly, this increases the chances that a newer compiler
version just works, which in turn means supporting several compiler
versions is easier now. Thus we will look into finally setting a minimum
version in the near future.
Toolchain and infrastructure:
- Upgrade to Rust 1.78.0.
This time around, due to how the kernel and Rust schedules have
aligned, there are two upgrades in fact. These allow us to remove one
more unstable feature ('offset_of') from the list, among other
improvements.
- Drop 'alloc' in-tree fork of the standard library crate, which means
all the unstable features used by 'alloc' (~30 language ones, ~60
library ones) are not a concern anymore.
- Support DWARFv5 via the '-Zdwarf-version' flag.
- Support zlib and zstd debuginfo compression via the
'-Zdebuginfo-compression' flag.
'kernel' crate:
- Support allocation flags ('GFP_*'), particularly in 'Box' (via
'BoxExt'), 'Vec' (via 'VecExt'), 'Arc' and 'UniqueArc', as well as in
the 'init' module APIs.
- Remove usage of the 'allocator_api' unstable feature.
- Remove 'try_' prefix in allocation APIs' names.
- Add 'VecExt' (an extension trait) to be able to drop the 'alloc'
fork.
- Add the '{make,to}_{upper,lower}case()' methods to 'CStr'/'CString'.
- Add the 'as_ptr' method to 'ThisModule'.
- Add the 'from_raw' method to 'ArcBorrow'.
- Add the 'into_unique_or_drop' method to 'Arc'.
- Display column number in the 'dbg!' macro output by applying the
equivalent change done to the standard library one.
- Migrate 'Work' to '#[pin_data]' thanks to the changes in the 'macros'
crate, which allows to remove an unsafe call in its 'new' associated
function.
- Prevent namespacing issues when using the '[try_][pin_]init!' macros
by changing the generated name of guard variables.
- Make the 'get' method in 'Opaque' const.
- Implement the 'Default' trait for 'LockClassKey'.
- Remove unneeded 'kernel::prelude' imports from doctests.
- Remove redundant imports.
'macros' crate:
- Add 'decl_generics' to 'parse_generics()' to support default values,
and use that to allow them in '#[pin_data]'.
Helpers:
- Trivial English grammar fix.
Documentation:
- Add section on Rust Kselftests to the "Testing" document.
- Expand the "Abstractions vs. bindings" section of the "General
Information" document.

Merge tag 'for-6.10/io_uring-20240511' of git://git.kernel.dk/linux
Pull io_uring updates from Jens Axboe:
- Greatly improve send zerocopy performance, by enabling coalescing of
sent buffers.
MSG_ZEROCOPY already does this with send(2) and sendmsg(2), but the
io_uring side did not. In local testing, the crossover point for send
zerocopy being faster is now around 3000 byte packets, and it
performs better than the sync syscall variants as well.
This feature relies on a shared branch with net-next, which was
pulled into both branches.
- Unification of how async preparation is done across opcodes.
Previously, opcodes that required extra memory for async retry would
allocate that as needed, using on-stack state until that was the
case. If async retry was needed, the on-stack state was adjusted
appropriately for a retry and then copied to the allocated memory.
This led to some fragile and ugly code, particularly for read/write
handling, and made storage retries more difficult than they needed to
be. Allocate the memory upfront, as it's cheap from our pools, and
use that state consistently both initially and also from the retry
side.
- Move away from using remap_pfn_range() for mapping the rings.
This is really not the right interface to use and can cause lifetime
issues or leaks. Additionally, it means the ring sq/cq arrays need to
be physically contigious, which can cause problems in production with
larger rings when services are restarted, as memory can be very
fragmented at that point.
Move to using vm_insert_page(s) for the ring sq/cq arrays, and apply
the same treatment to mapped ring provided buffers. This also helps
unify the code we have dealing with allocating and mapping memory.
Hard to see in the diffstat as we're adding a few features as well,
but this kills about ~400 lines of code from the codebase as well.
- Add support for bundles for send/recv.
When used with provided buffers, bundles support sending or receiving
more than one buffer at the time, improving the efficiency by only
needing to call into the networking stack once for multiple sends or
receives.
- Tweaks for our accept operations, supporting both a DONTWAIT flag for
skipping poll arm and retry if we can, and a POLLFIRST flag that the
application can use to skip the initial accept attempt and rely
purely on poll for triggering the operation. Both of these have
identical flags on the receive side already.
- Make the task_work ctx locking unconditional.
We had various code paths here that would do a mix of lock/trylock
and set the task_work state to whether or not it was locked. All of
that goes away, we lock it unconditionally and get rid of the state
flag indicating whether it's locked or not.
The state struct still exists as an empty type, can go away in the
future.
- Add support for specifying NOP completion values, allowing it to be
used for error handling testing.
- Use set/test bit for io-wq worker flags. Not strictly needed, but
also doesn't hurt and helps silence a KCSAN warning.
- Cleanups for io-wq locking and work assignments, closing a tiny race
where cancelations would not be able to find the work item reliably.
- Misc fixes, cleanups, and improvements

Pull netfs updates from Christian Brauner:
"This reworks the netfslib writeback implementation so that pages read
from the cache are written to the cache through ->writepages(),
thereby allowing the fscache page flag to be retired.
The reworking also:
- builds on top of the new writeback_iter() infrastructure
- makes it possible to use vectored write RPCs as discontiguous
streams of pages can be accommodated
- makes it easier to do simultaneous content crypto and stream
division
- provides support for retrying writes and re-dividing a stream
- replaces the ->launder_folio() op, so that ->writepages() is used
instead
- uses mempools to allocate the netfs_io_request and
netfs_io_subrequest structs to avoid allocation failure in the
writeback path
Some code that uses the fscache page flag is retained for
compatibility purposes with nfs and ceph. The code is switched to
using the synonymous private_2 label instead and marked with
deprecation comments.
The merge commit contains additional details on the new algorithm that
I've left out of here as it would probably be excessively detailed.

Pull misc vfs updates from Christian Brauner:
"This contains the usual miscellaneous features, cleanups, and fixes
for vfs and individual fses.
Features:
- Free up FMODE_* bits. I've freed up bits 6, 7, 8, and 24. That
means we now have six free FMODE_* bits in total (but bit #6
already got used for FMODE_WRITE_RESTRICTED)
- Add FOP_HUGE_PAGES flag (follow-up to FMODE_* cleanup)
- Add fd_raw cleanup class so we can make use of automatic cleanup
provided by CLASS(fd_raw, f)(fd) for O_PATH fds as well
- Optimize seq_puts()
- Simplify __seq_puts()
- Add new anon_inode_getfile_fmode() api to allow specifying f_mode
instead of open-coding it in multiple places
- Annotate struct file_handle with __counted_by() and use
struct_size()
- Warn in get_file() whether f_count resurrection from zero is
attempted (epoll/drm discussion)
- Folio-sophize aio
- Export the subvolume id in statx() for both btrfs and bcachefs
- Relax linkat(AT_EMPTY_PATH) requirements
- Add F_DUPFD_QUERY fcntl() allowing to compare two file descriptors
for dup*() equality replacing kcmp()
Cleanups:
- Compile out swapfile inode checks when swap isn't enabled
- Use (1 << n) notation for FMODE_* bitshifts for clarity
- Remove redundant variable assignment in fs/direct-io
- Cleanup uses of strncpy in orangefs
- Speed up and cleanup writeback
- Move fsparam_string_empty() helper into header since it's currently
open-coded in multiple places
- Add kernel-doc comments to proc_create_net_data_write()
- Don't needlessly read dentry->d_flags twice
Fixes:
- Fix out-of-range warning in nilfs2
- Fix ecryptfs overflow due to wrong encryption packet size
calculation
- Fix overly long line in xfs file_operations (follow-up to FMODE_*
cleanup)
- Don't raise FOP_BUFFER_{R,W}ASYNC for directories in xfs (follow-up
to FMODE_* cleanup)
- Don't call xfs_file_open from xfs_dir_open (follow-up to FMODE_*
cleanup)
- Fix stable offset api to prevent endless loops
- Fix afs file server rotations
- Prevent xattr node from overflowing the eraseblock in jffs2
- Move fdinfo PTRACE_MODE_READ procfs check into the .permission()
operation instead of .open() operation since this caused userspace
regressions"
