Pull cifs client updates from Steve French:
"The largest subset of this is from David Howells et al: making the
cifs/smb3 driver pass iov_iters down to the lowest layers, directly to
the network transport rather than passing lists of pages around,
helping multiple areas:
- Pin user pages, thereby fixing the race between concurrent DIO read
and fork, where the pages containing the DIO read buffer may end up
belonging to the child process and not the parent - with the result
that the parent might not see the retrieved data.
- cifs shouldn't take refs on pages extracted from non-user-backed
iterators (eg. KVEC). With these changes, cifs will apply the
appropriate cleanup.
- Making it easier to transition to using folios in cifs rather than
pages by dealing with them through BVEC and XARRAY iterators.
- Allowing cifs to use the new splice function
The remainder are:
- fixes for stable, including various fixes for uninitialized memory,
wrong length field causing mount issue to very old servers,
important directory lease fixes and reconnect fixes
- cleanups (unused code removal, change one element array usage, and
a change form strtobool to kstrtobool, and Kconfig cleanups)
- SMBDIRECT (RDMA) fixes including iov_iter integration and UAF fixes
- reconnect fixes
- multichannel fixes, including improving channel allocation (to
least used channel)

"Two significant security enhancements are part of this release:
- NFSD's RPC header encoding and decoding, including RPCSEC GSS and
gssproxy header parsing, has been overhauled to make it more
memory-safe.
- Support for Kerberos AES-SHA2-based encryption types has been added
for both the NFS client and server. This provides a clean path for
deprecating and removing insecure encryption types based on DES and
SHA-1. AES-SHA2 is also FIPS-140 compliant, so that NFS with
Kerberos may now be used on systems with fips enabled.
In addition to these, NFSD is now able to handle crossing into an
auto-mounted mount point on an exported NFS mount. A number of fixes
have been made to NFSD's server-side copy implementation.
RPC metrics have been converted to per-CPU variables. This helps
reduce unnecessary cross-CPU and cross-node memory bus traffic, and
significantly reduces noise when KCSAN is enabled"

Pull ATA updates from Damien Le Moal:
- Small cleanup of the pata_octeon driver to drop a useless platform
callback (Uwe)
- Simplify ata_scsi_cmd_error_handler() code using the fact that
ap->ops->error_handler is NULL most of the time (Wenchao)
- Several patches improving libata error handling. This is in
preparation for supporting the command duration limits (CDL) feature.
The changes allow handling corner cases of ATA NCQ errors which do
not happen with regular drives but will be triggered with CDL drives
(Niklas)
- Simplify the qc_fill_rtf operation (me)
- Improve SCSI command translation for REPORT_SUPPORTED_OPERATION_CODES
command (me)
- Cleanup of libata FUA handling.
This falls short of enabling FUA for ATA drives that support it by
default as there were concerns that old drives would break. The
series however fixes several issues with the FUA support to ensure
that FUA is reported as being supported only for drives that can
handle all possible write cases (NCQ and non-NCQ). A check in the
block layer is also added to ensure that we never see read FUA
commands (current behavior) (me)
- Several patches to move the old PARIDE (parallel port IDE) driver to
libata as pata_parport. Given that this driver also needs protocol
modules, the driver code resides in its own pata_parport directoy
under drivers/ata (Ondrej)

- Improve 2 of DM's shrinker names to reflect their use.
- Fix the DM flakey target to not corrupt the zero page. Fix dm-flakey
on 32-bit hughmem systems by using bvec_kmap_local instead of
page_address. Also, fix logic used when imposing the
"corrupt_bio_byte" feature.
- Stop using WQ_UNBOUND for DM verity target's verify_wq because it
causes significant Android latencies on ARM64 (and doesn't show real
benefit on other architectures).
- Add negative check to catch simple case of a DM table referencing
itself. More complex scenarios that use intermediate devices to
self-reference still need to be avoided/handled in userspace.
- Fix DM core's resize to only send one uevent instead of two. This
fixes a race with udev, that if udev wins, will cause udev to miss
uevents (which caused premature unmount attempts by systemd).
- Add cond_resched() to workqueue functions in DM core, dn-thin and
dm-cache so that their loops aren't the cause of unintended cpu
scheduling fairness issues.
- Fix all of DM's checkpatch errors and warnings (famous last words).

bpf: add missing header file include
Commit 74e19ef0ff80 ("uaccess: Add speculation barrier to
copy_from_user()") built fine on x86-64 and arm64, and that's the extent
of my local build testing.
It turns out those got the <linux/nospec.h> include incidentally through
other header files (<linux/kvm_host.h> in particular), but that was not
true of other architectures, resulting in build errors
kernel/bpf/core.c: In function ‘___bpf_prog_run’:
kernel/bpf/core.c:1913:3: error: implicit declaration of function ‘barrier_nospec’
so just make sure to explicitly include the proper <linux/nospec.h>
header file to make everybody see it.
The ->writepage() and ->writepages() operations are supposed to write
entire pages. However, on filesystems with a block size smaller than
PAGE_SIZE, __gfs2_jdata_writepage() only adds the first block to the
current transaction instead of adding the entire page. Fix that.

The history is a little long for this series, as it was intended to be
sent for v6.2. However some last minute issues forced us to postpone it
to v6.3.

Pull networking updates from Jakub Kicinski:
"Core:
- Add dedicated kmem_cache for typical/small skb->head, avoid having
to access struct page at kfree time, and improve memory use.
- Introduce sysctl to set default RPS configuration for new netdevs.
- Define Netlink protocol specification format which can be used to
describe messages used by each family and auto-generate parsers.
Add tools for generating kernel data structures and uAPI headers.
- Expose all net/core sysctls inside netns.
- Remove 4s sleep in netpoll if carrier is instantly detected on
boot.
- Add configurable limit of MDB entries per port, and port-vlan.
- Continue populating drop reasons throughout the stack.
- Retire a handful of legacy Qdiscs and classifiers.
Protocols:
- Support IPv4 big TCP (TSO frames larger than 64kB).
- Add IP_LOCAL_PORT_RANGE socket option, to control local port range
on socket by socket basis.
- Track and report in procfs number of MPTCP sockets used.
- Support mixing IPv4 and IPv6 flows in the in-kernel MPTCP path
manager.
- IPv6: don't check net.ipv6.route.max_size and rely on garbage
collection to free memory (similarly to IPv4).
- Support Penultimate Segment Pop (PSP) flavor in SRv6 (RFC8986).
- ICMP: add per-rate limit counters.
- Add support for user scanning requests in ieee802154.
- Remove static WEP support.
- Support minimal Wi-Fi 7 Extremely High Throughput (EHT) rate
reporting.
- WiFi 7 EHT channel puncturing support (client & AP).
BPF:
- Add a rbtree data structure following the "next-gen data structure"
precedent set by recently added linked list, that is, by using
kfunc + kptr instead of adding a new BPF map type.
- Expose XDP hints via kfuncs with initial support for RX hash and
timestamp metadata.
- Add BPF_F_NO_TUNNEL_KEY extension to bpf_skb_set_tunnel_key to
better support decap on GRE tunnel devices not operating in collect
metadata.
- Improve x86 JIT's codegen for PROBE_MEM runtime error checks.
- Remove the need for trace_printk_lock for bpf_trace_printk and
bpf_trace_vprintk helpers.
- Extend libbpf's bpf_tracing.h support for tracing arguments of
kprobes/uprobes and syscall as a special case.
- Significantly reduce the search time for module symbols by
livepatch and BPF.
- Enable cpumasks to be used as kptrs, which is useful for tracing
programs tracking which tasks end up running on which CPUs in
different time intervals.
- Add support for BPF trampoline on s390x and riscv64.
- Add capability to export the XDP features supported by the NIC.
- Add __bpf_kfunc tag for marking kernel functions as kfuncs.
- Add cgroup.memory=nobpf kernel parameter option to disable BPF
memory accounting for container environments.
Netfilter:
- Remove the CLUSTERIP target. It has been marked as obsolete for
years, and we still have WARN splats wrt races of the out-of-band
/proc interface installed by this target.
- Add 'destroy' commands to nf_tables. They are identical to the
existing 'delete' commands, but do not return an error if the
referenced object (set, chain, rule...) did not exist.
Driver API:
- Improve cpumask_local_spread() locality to help NICs set the right
IRQ affinity on AMD platforms.
- Separate C22 and C45 MDIO bus transactions more clearly.
- Introduce new DCB table to control DSCP rewrite on egress.
- Support configuration of Physical Layer Collision Avoidance (PLCA)
Reconciliation Sublayer (RS) (802.3cg-2019). Modern version of
shared medium Ethernet.
- Support for MAC Merge layer (IEEE 802.3-2018 clause 99). Allowing
preemption of low priority frames by high priority frames.
- Add support for controlling MACSec offload using netlink SET.
- Rework devlink instance refcounts to allow registration and
de-registration under the instance lock. Split the code into
multiple files, drop some of the unnecessarily granular locks and
factor out common parts of netlink operation handling.
- Add TX frame aggregation parameters (for USB drivers).
- Add a new attr TCA_EXT_WARN_MSG to report TC (offload) warning
messages with notifications for debug.
- Allow offloading of UDP NEW connections via act_ct.
- Add support for per action HW stats in TC.
- Support hardware miss to TC action (continue processing in SW from
a specific point in the action chain).
- Warn if old Wireless Extension user space interface is used with
modern cfg80211/mac80211 drivers. Do not support Wireless
Extensions for Wi-Fi 7 devices at all. Everyone should switch to
using nl80211 interface instead.
- Improve the CAN bit timing configuration. Use extack to return
error messages directly to user space, update the SJW handling,
including the definition of a new default value that will benefit
CAN-FD controllers, by increasing their oscillator tolerance.

Pull s390 updates from Heiko Carstens:
- Large cleanup of the con3270/tty3270 driver. Among others this fixes:
- Background Color Support
- ASCII Line Character Support
- VT100 Support
- Geometries other than 80x24
- Cleanup and improve cmpxchg() code. Also add cmpxchg_user_key() to
uaccess functions, which will be used by KVM to access KVM guest
memory with a specific storage key
- Add support for user space events counting to CPUMF
- Cleanup the vfio/ccw code, which also allows now to properly support
2K Format-2 IDALs
- Move kernel page table allocation and initialization to decompressor,
which finally allows to enter the kernel with dynamic address
translation enabled. This in turn allows to get rid of code with
special handling in the kernel, which has to distinguish if DAT is on
or off
- Replace kretprobe with rethook
- Various improvements to vfio/ap queue resets:
- Use TAPQ to verify completion of a reset in progress rather than
multiple invocations of ZAPQ.
- Check TAPQ response codes when verifying successful completion of
ZAPQ.
- Fix erroneous handling of some error response codes.
- Increase the maximum amount of time to wait for successful
completion of ZAPQ
- Rework system call wrappers to get rid of alias functions, which were
only left on s390
- Cleanup diag288_wdt watchdog driver. It has been agreed on with
Guenter Roeck that this goes upstream via the s390 tree
- Add missing loadparm parameter handling for list-directed ECKD
ipl/reipl
- Various improvements to memory detection code
- Remove arch_cpu_idle_time() since the current implementation is
broken, and allows user space observable accounted idle times which
can temporarily decrease
- Add Reset DAT-Protection support: (only) allow to change PTEs from RO
to RW with a new RDP instruction. Unlike the currently used IPTE
instruction, this does not necessarily guarantee that TLBs of all
CPUs are synchronously flushed; and that remote CPUs can see spurious
protection faults. The overall improvement for not requiring an all
CPU synchronization, like it is required with IPTE, should be
beneficial
- Fix KFENCE page fault reporting

uaccess: Add speculation barrier to copy_from_user()
The results of "access_ok()" can be mis-speculated. The result is that
you can end speculatively:
if (access_ok(from, size))
// Right here
even for bad from/size combinations. On first glance, it would be ideal
to just add a speculation barrier to "access_ok()" so that its results
can never be mis-speculated.
But there are lots of system calls just doing access_ok() via
"copy_to_user()" and friends (example: fstat() and friends). Those are
generally not problematic because they do not _consume_ data from
userspace other than the pointer. They are also very quick and common
system calls that should not be needlessly slowed down.
"copy_from_user()" on the other hand uses a user-controller pointer and
is frequently followed up with code that might affect caches. Take
something like this:
if (!copy_from_user(&kernelvar, uptr, size))
do_something_with(kernelvar);
If userspace passes in an evil 'uptr' that *actually* points to a kernel
addresses, and then do_something_with() has cache (or other)
side-effects, it could allow userspace to infer kernel data values.
Add a barrier to the common copy_from_user() code to prevent
mis-speculated values which happen after the copy.
Also add a stub for architectures that do not define barrier_nospec().
This makes the macro usable in generic code.
Since the barrier is now usable in generic code, the x86 #ifdef in the
BPF code can also go away.

Pull thermal control updates from Rafael Wysocki:
"The majority of changes here are related to the general switch-over to
using arrays of generic trip point structures registered along with a
thermal zone instead of trip point callbacks (this has been done
mostly by Daniel Lezcano with some help from yours truly on the Intel
drivers front).
Apart from that and the related reorganization of code, there are some
enhancements of the existing driver and a new Mediatek Low Voltage
Thermal Sensor (LVTS) driver. The Intel powerclamp undergoes a major
rework so it will use the generic idle_inject facility for CPU idle
time injection going forward and it will take additional module
parameters for specifying the subset of CPUs to be affected by it
(work done by Srinivas Pandruvada).
Also included are assorted fixes and a whole bunch of cleanups.
Specifics:
- Rework a large bunch of drivers to use the generic thermal trip
structure and use the opportunity to do more cleanups by removing
unused functions from the OF code (Daniel Lezcano)
- Remove core header inclusion from drivers (Daniel Lezcano)
- Fix some locking issues related to the generic thermal trip rework
(Johan Hovold)

cooling devices if the thermal class has not been registered
(Rafael Wysocki)
- Add trip point initialization helper functions for ACPI-defined
trip points and modify two thermal drivers to use them (Rafael
Wysocki, Daniel Lezcano)
- Make the core thermal control code use sysfs_emit_at() instead of
scnprintf() where applicable (ye xingchen)
- Consolidate code accessing the Intel TCC (Thermal Control
Circuitry) MSRs by introducing library functions for that and
making the TCC-related code in thermal drivers use them (Zhang Rui)
- Enhance the x86_pkg_temp_thermal driver to support dynamic tjmax
changes (Zhang Rui)
- Address an "unsigned expression compared with zero" warning in the
intel_soc_dts_iosf thermal driver (Yang Li)

- Miscellaneous fixes, perhaps most notably:
- Throttling callback invocation based on the number of callbacks
that are now ready to invoke instead of on the total number of
callbacks
- Several patches that suppress false-positive boot-time
diagnostics, for example, due to lockdep not yet being
initialized
- Make expedited RCU CPU stall warnings dump stacks of any tasks
that are blocking the stalled grace period. (Normal RCU CPU
stall warnings have done this for many years)
- Lazy-callback fixes to avoid delays during boot, suspend, and
resume. (Note that lazy callbacks must be explicitly enabled, so
this should not (yet) affect production use cases)
- Make kfree_rcu() and friends take advantage of polled grace periods,
thus reducing memory footprint by almost two orders of magnitude,
admittedly on a microbenchmark
This also begins the transition from kfree_rcu(p) to
kfree_rcu_mightsleep(p). This transition was motivated by bugs where
kfree_rcu(p), which can block, was typed instead of the intended
kfree_rcu(p, rh)
- SRCU updates, perhaps most notably fixing a bug that causes SRCU to
fail when booted on a system with a non-zero boot CPU. This
surprising situation actually happens for kdump kernels on the
powerpc architecture
This also adds an srcu_down_read() and srcu_up_read(), which act like
srcu_read_lock() and srcu_read_unlock(), but allow an SRCU read-side
critical section to be handed off from one task to another
- Clean up the now-useless SRCU Kconfig option
There are a few more commits that are not yet acked or pulled into
maintainer trees, and these will be in a pull request for a later
merge window
- RCU-tasks updates, perhaps most notably these fixes:
- A strange interaction between PID-namespace unshare and the
RCU-tasks grace period that results in a low-probability but
very real hang
- A race between an RCU tasks rude grace period on a single-CPU
system and CPU-hotplug addition of the second CPU that can
result in a too-short grace period
- A race between shrinking RCU tasks down to a single callback
list and queuing a new callback to some other CPU, but where
that queuing is delayed for more than an RCU grace period. This
can result in that callback being stranded on the non-boot CPU
- Torture-test updates and fixes
- Torture-test scripting updates and fixes

- When per-cpu workqueue workers expire after sitting idle for too
long, they used to wake up to the CPU that they're bound to in order
to exit. This unfortunately could cause unwanted disturbances on CPUs
isolated for e.g. RT applications.
The worker exit path is restructured so that an existing worker is
unbound from its CPU before being woken up for the last time,
allowing it to migrate away from an isolated CPU for exiting.
- A couple debug improvements. Watchdog dump is made more compact and
workqueue now warns if used-after-free during the RCU grace period

Pull timer updates from Thomas Gleixner:
"Updates for timekeeping, timers and clockevent/source drivers:
Core:
- Yet another round of improvements to make the clocksource watchdog
more robust:
- Relax the clocksource-watchdog skew criteria to match the NTP
criteria.
- Temporarily skip the watchdog when high memory latencies are
detected which can lead to false-positives.
- Provide an option to enable TSC skew detection even on systems
where TSC is marked as reliable.
Sigh!
- Initialize the restart block in the nanosleep syscalls to be
directed to the no restart function instead of doing a partial
setup on entry.
This prevents an erroneous restart_syscall() invocation from
corrupting user space data. While such a situation is clearly a
user space bug, preventing this is a correctness issue and caters
to the least suprise principle.
- Ignore the hrtimer slack for realtime tasks in schedule_hrtimeout()
to align it with the nanosleep semantics.
Drivers:
- The obligatory new driver bindings for Mediatek, Rockchip and
RISC-V variants.
- Add support for the C3STOP misfeature to the RISC-V timer to handle
the case where the timer stops in deeper idle state.
- Set up a static key in the RISC-V timer correctly before first use.

drm/fb-helper: Remove drm_fb_helper_unprepare() from drm_fb_helper_fini()
Move drm_fb_helper_unprepare() from drm_fb_helper_fini() into the
calling fbdev implementation. Avoids a possible stale mutex with
generic fbdev code.
As indicated by its name, drm_fb_helper_prepare() prepares struct
drm_fb_helper before setting up the fbdev support with a call to
drm_fb_helper_init(). In legacy fbdev emulation, this happens next
to each other. If successful, drm_fb_helper_fini() later tear down
the fbdev device and also unprepare via drm_fb_helper_unprepare().
Generic fbdev emulation prepares struct drm_fb_helper immediately
after allocating the instance. It only calls drm_fb_helper_init()
as part of processing a hotplug event. If the hotplug-handling fails,
it runs drm_fb_helper_fini(). This unprepares the fb-helper instance
and the next hotplug event runs on stale data.
Solve this by moving drm_fb_helper_unprepare() from drm_fb_helper_fini()
into the fbdev implementations. Call it right before freeing the
fb-helper instance.
