Pull tdx updates from Dave Hansen:
"These essentially refine some interactions between TDX guests and
VMMs.
The first leverages a new TDX module feature to runtime disable the
ability for a VM to inject #VE exceptions. Before this feature, there
was only a static on/off switch and the guest had to panic if it was
configured in a bad state.
The second lets the guest opt in to be able to access the topology
CPUID leaves. Before this, accesses to those leaves would #VE.
For both of these, it would have been nicest to just change the
default behavior, but some pesky "other" OSes evidently need to retain
the legacy behavior.
Summary:
- Add new infrastructure for reading TDX metadata
- Use the newly-available metadata to:
- Disable potentially nasty #VE exceptions
- Get more complete CPU topology information from the VMM"

Networking changes for 6.13.
The most significant set of changes is the per netns RTNL. The new
behavior is disabled by default, regression risk should be contained.
Notably the new config knob PTP_1588_CLOCK_VMCLOCK will inherit its
default value from PTP_1588_CLOCK_KVM, as the first is intended to be
a more reliable replacement for the latter.
Core
----
- Started a very large, in-progress, effort to make the RTNL lock
scope per network-namespace, thus reducing the lock contention
significantly in the containerized use-case, comprising:
- RCU-ified some relevant slices of the FIB control path
- introduce basic per netns locking helpers
- namespacified the IPv4 address hash table
- remove rtnl_register{,_module}() in favour of rtnl_register_many()
- refactor rtnl_{new,del,set}link() moving as much validation as
possible out of RTNL lock
- convert all phonet doit() and dumpit() handlers to RCU
- convert IPv4 addresses manipulation to per-netns RTNL
- convert virtual interface creation to per-netns RTNL
the per-netns lock infra is guarded by the CONFIG_DEBUG_NET_SMALL_RTNL
knob, disabled by default ad interim.
- Introduce NAPI suspension, to efficiently switching between busy
polling (NAPI processing suspended) and normal processing.
- Migrate the IPv4 routing input, output and control path from direct
ToS usage to DSCP macros. This is a work in progress to make ECN
handling consistent and reliable.
- Add drop reasons support to the IPv4 rotue input path, allowing
better introspection in case of packets drop.
- Make FIB seqnum lockless, dropping RTNL protection for read
access.
- Make inet{,v6} addresses hashing less predicable.
- Allow providing timestamp OPT_ID via cmsg, to correlate TX packets
and timestamps
Things we sprinkled into general kernel code
--------------------------------------------
- Add small file operations for debugfs, to reduce the struct ops size.
- Refactoring and optimization for the implementation of page_frag API,
This is a preparatory work to consolidate the page_frag
implementation.
Netfilter
---------
- Optimize set element transactions to reduce memory consumption
- Extended netlink error reporting for attribute parser failure.
- Make legacy xtables configs user selectable, giving users
the option to configure iptables without enabling any other config.
- Address a lot of false-positive RCU issues, pointed by recent
CI improvements.
BPF
---
- Put xsk sockets on a struct diet and add various cleanups. Overall,
this helps to bump performance by 12% for some workloads.
- Extend BPF selftests to increase coverage of XDP features in
combination with BPF cpumap.
- Optimize and homogenize bpf_csum_diff helper for all archs and also
add a batch of new BPF selftests for it.
- Extend netkit with an option to delegate skb->{mark,priority}
scrubbing to its BPF program.
- Make the bpf_get_netns_cookie() helper available also to tc(x) BPF
programs.
Protocols
---------
- Introduces 4-tuple hash for connected udp sockets, speeding-up
significantly connected sockets lookup.
- Add a fastpath for some TCP timers that usually expires after close,
the socket lock contention.
- Add inbound and outbound xfrm state caches to speed up state lookups.
- Avoid sending MPTCP advertisements on stale subflows, reducing
risks on loosing them.
- Make neighbours table flushing more scalable, maintaining per device
neigh lists.
Driver API
----------
- Introduce a unified interface to configure transmission H/W shaping,
and expose it to user-space via generic-netlink.
- Add support for per-NAPI config via netlink. This makes napi
configuration persistent across queues removal and re-creation.
Requires driver updates, currently supported drivers are:
nVidia/Mellanox mlx4 and mlx5, Broadcom brcm and Intel ice.
- Add ethtool support for writing SFP / PHY firmware blocks.
- Track RSS context allocation from ethtool core.
- Implement support for mirroring to DSA CPU port, via TC mirror
offload.
- Consolidate FDB updates notification, to avoid duplicates on
device-specific entries.
- Expose DPLL clock quality level to the user-space.
- Support master-slave PHY config via device tree.
Tests and tooling
-----------------
- forwarding: introduce deferred commands, to simplify
the cleanup phase
Drivers
-------
- Updated several drivers - Amazon vNic, Google vNic, Microsoft vNic,
Intel e1000e and Broadcom Tigon3 - to use netdev-genl to link the
IRQs and queues to NAPI IDs, allowing busy polling and better
introspection.

soc: driver updates for 6.12
Nothing particular important in the SoC driver updates, just the usual
improvements to for drivers/soc and a couple of subsystems that don't
fit anywhere else:
- The largest set of updates is for Qualcomm SoC drivers, extending the
set of supported features for additional SoCs in the QSEECOM, LLCC
and socinfo drivers.a
- The ti_sci firmware driver gains support for power managment
- The drivers/reset subsystem sees a rework of the microchip
sparx5 and amlogic reset drivers to support additional chips,
plus a few minor updates on other platforms
- The SCMI firmware interface driver gains support for two protocol
extensions, allowing more flexible use of the shared memory area
and new DT binding properties for configurability.
- Mediatek SoC drivers gain support for power managment on the MT8188
SoC and a new driver for DVFS.
- The AMD/Xilinx ZynqMP SoC drivers gain support for system reboot
and a few bugfixes
- The Hisilicon Kunpeng HCCS driver gains support for configuring
lanes through sysfs
Finally, there are cleanups and minor fixes for drivers/soc, drivers/bus,
and drivers/memory, including changing back the .remove_new callback
to .remove, as well as a few other updates for freescale (powerpc)
soc drivers, NXP i.MX soc drivers, cznic turris platform driver, memory
controller drviers, TI OMAP SoC drivers, and Tegra firmware drivers

soc: devicetree updates for 6.13
This release adds the devicetree files for an impressive number of new
SoC variants, though as expected these are all related to others we
already support:
- The microchip sam9x7 devicetree is now added, after the device driver
and platform code has already made it in. This is likely the last ARMv5
(!) platform to ever get added, updating the 20+ year old at91/sam9
platform wtih DDR3 memory and gigabit ethernet.
- On the Apple platform, there are now devicetree files for a number of
A-series SoCs in addition to the M-series ones, these are used
primarily in phones and tablets, but are closely related to the
already supported chips.
- Samsung Exynos 8895 and Exynos 990 are more phone SoCs used in older
Samsung Galaxy phones.
- Qualcomm Snapdragon 778G (SM7325) is another phone SoC, closely related
to the Snapdragon 7c+ Gen 3 (SC7280) used in low-end laptops.
- Rockchip RK3528 and RK3576 are new variants of their TV box and Tablet
chips, still using the older ARMv8.0 cores from RK3328/RK3399 but
with a newer process and other improvements from the RK35xx (otherwise
ARMv8.2) chips. RK3566T and RK3399-S are also added, these are just
lower-cost versions of their normal counterparts.
- TI J742S2 is a feature-reduced version of the J784s4
industrial/automotive SoC, with fewer CPU cores.
- Sophgo SG2002 is an embedded SoC with one RISC-V (C906) and one ARM
(Cortex-A53) core, at this point support is only added for running
on the RISC-V side on the LicheeRV Nano board.
A total of 92 new .dts files describing individual machines is added,
which must be a new record. The majority of these is for the newly added
chips above, notably all the Apple phones and tablets. The other new
machines include nine industrial/embedded boards with NXP i.MX6 or i.MX8
SoCs, eight for Rockchips RK35XX and one or two each for Rockchips RV1109,
RK3308, Allwinner A33, Tegra 234, Qualcomm qcs9100/sc8280xp/x1e80100,
TI AM625 and Starfive JH7110.
As usual there are also many newlyad added features in existing boards
as well as cleanups and minor bugfixes.

asm-generic updates for 6.13
These are a number of unrelated cleanups, generally simplifying the
architecture specific header files:
- A series from Al Viro simplifies asm/vga.h, after it turns out that
most of it can be generalized.
- A series from Julian Vetter adds a common version of
memcpy_{to,from}io() and memset_io() and changes most architectures
to use that instead of their own implementation
- A series from Niklas Schnelle concludes his work to make PC
style inb()/outb() optional
- Nicolas Pitre contributes improvements for the generic do_div()
helper
- Christoph Hellwig adds a generic version of page_to_phys()
and phys_to_page(), replacing the slightly different architecture
specific definitions.
- Uwe Kleine-Koenig has a minor cleanup for ioctl definitions

ftrace updates for v6.13:
- Merged tag ftrace-v6.12-rc4 There was a fix to locking in register_ftrace_graph() for shadow stacks that was sent upstream. But this code was also being rewritten, and the locking fix was needed. Merging this fix was required to continue the work. - Restructure the function graph shadow stack to prepare it for use with kretprobes With the goal of merging the shadow stack logic of function graph and kretprobes, some more restructuring of the function shadow stack is required. Move out function graph specific fields from the fgraph infrastructure and store it on the new stack variables that can pass data from the entry callback to the exit callback. Hopefully, with this change, the merge of kretprobes to use fgraph shadow stacks will be ready by the next merge window. - Make shadow stack 4k instead of using PAGE_SIZE. Some architectures have very large PAGE_SIZE values which make its use for shadow stacks waste a lot of memory. - Give shadow stacks its own kmem cache. When function graph is started, every task on the system gets a shadow stack. In the future, shadow stacks may not be 4K in size. Have it have its own kmem cache so that whatever size it becomes will still be efficient in allocations. - Initialize profiler graph ops as it will be needed for new updates to fgraph - Convert to use guard(mutex) for several ftrace and fgraph functions - Add more comments and documentation - Show function return address in function graph tracer Add an option to show the caller of a function at each entry of the function graph tracer, similar to what the function tracer does. - Abstract out ftrace_regs from being used directly like pt_regs ftrace_regs was created to store a partial pt_regs. It holds only the registers and stack information to get to the function arguments and return values. On several archs, it is simply a wrapper around pt_regs. But some users would access ftrace_regs directly to get the pt_regs which will not work on all archs. Make ftrace_regs an abstract structure that requires all access to its fields be through accessor functions. - Show how long it takes to do function code modifications When code modification for function hooks happen, it always had the time recorded in how long it took to do the conversion. But this value was never exported. Recently the code was touched due to new ROX modification handling that caused a large slow down in doing the modifications and had a significant impact on boot times. Expose the timings in the dyn_ftrace_total_info file. This file was created a while ago to show information about memory usage and such to implement dynamic function tracing. It's also an appropriate file to store the timings of this modification as well. This will make it easier to see the impact of changes to code modification on boot up timings. - Other clean ups and small fixes -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCZztrUxQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qnnNAQD6w4q9VQ7oOE2qKLqtnj87h4c1GqKn SPkpEfC3n/ATEAD/fnYjT/eOSlHiGHuD/aTA+U/bETrT99bozGM/4mFKEgY= =6nCa -----END PGP SIGNATURE----- Merge tag 'ftrace-v6.13' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull ftrace updates from Steven Rostedt: - Restructure the function graph shadow stack to prepare it for use with kretprobes With the goal of merging the shadow stack logic of function graph and kretprobes, some more restructuring of the function shadow stack is required.

A rather large update for timekeeping and timers:
- The final step to get rid of auto-rearming posix-timers
posix-timers are currently auto-rearmed by the kernel when the signal
of the timer is ignored so that the timer signal can be delivered once
the corresponding signal is unignored.
This requires to throttle the timer to prevent a DoS by small intervals
and keeps the system pointlessly out of low power states for no value.
This is a long standing non-trivial problem due to the lock order of
posix-timer lock and the sighand lock along with life time issues as
the timer and the sigqueue have different life time rules.
Cure this by:
* Embedding the sigqueue into the timer struct to have the same life
time rules. Aside of that this also avoids the lookup of the timer
in the signal delivery and rearm path as it's just a always valid
container_of() now.
* Queuing ignored timer signals onto a seperate ignored list.
* Moving queued timer signals onto the ignored list when the signal is
switched to SIG_IGN before it could be delivered.
* Walking the ignored list when SIG_IGN is lifted and requeue the
signals to the actual signal lists. This allows the signal delivery
code to rearm the timer.
This also required to consolidate the signal delivery rules so they are
consistent across all situations. With that all self test scenarios
finally succeed.
- Core infrastructure for VFS multigrain timestamping
This is required to allow the kernel to use coarse grained time stamps
by default and switch to fine grained time stamps when inode attributes
are actively observed via getattr().
These changes have been provided to the VFS tree as well, so that the
VFS specific infrastructure could be built on top.
- Cleanup and consolidation of the sleep() infrastructure
* Move all sleep and timeout functions into one file
* Rework udelay() and ndelay() into proper documented inline functions
and replace the hardcoded magic numbers by proper defines.
* Rework the fsleep() implementation to take the reality of the timer
wheel granularity on different HZ values into account. Right now the
boundaries are hard coded time ranges which fail to provide the
requested accuracy on different HZ settings.
* Update documentation for all sleep/timeout related functions and fix
up stale documentation links all over the place
* Fixup a few usage sites
- Rework of timekeeping and adjtimex(2) to prepare for multiple PTP clocks
A system can have multiple PTP clocks which are participating in
seperate and independent PTP clock domains. So far the kernel only
considers the PTP clock which is based on CLOCK TAI relevant as that's
the clock which drives the timekeeping adjustments via the various user
space daemons through adjtimex(2).
The non TAI based clock domains are accessible via the file descriptor
based posix clocks, but their usability is very limited. They can't be
accessed fast as they always go all the way out to the hardware and
they cannot be utilized in the kernel itself.
As Time Sensitive Networking (TSN) gains traction it is required to
provide fast user and kernel space access to these clocks.
The approach taken is to utilize the timekeeping and adjtimex(2)
infrastructure to provide this access in a similar way how the kernel
provides access to clock MONOTONIC, REALTIME etc.
Instead of creating a duplicated infrastructure this rework converts
timekeeping and adjtimex(2) into generic functionality which operates
on pointers to data structures instead of using static variables.
This allows to provide time accessors and adjtimex(2) functionality for
the independent PTP clocks in a subsequent step.
- Consolidate hrtimer initialization
hrtimers are set up by initializing the data structure and then
seperately setting the callback function for historical reasons.
That's an extra unnecessary step and makes Rust support less straight
forward than it should be.
Provide a new set of hrtimer_setup*() functions and convert the core
code and a few usage sites of the less frequently used interfaces over.
The bulk of the htimer_init() to hrtimer_setup() conversion is already
prepared and scheduled for the next merge window.
- Drivers:
* Ensure that the global timekeeping clocksource is utilizing the
cluster 0 timer on MIPS multi-cluster systems.
Otherwise CPUs on different clusters use their cluster specific
clocksource which is not guaranteed to be synchronized with other
clusters.
* Mostly boring cleanups, fixes, improvements and code movement

First step of consolidating the VDSO data page handling:
The VDSO data page handling is architecture specific for historical
reasons, but there is no real technical reason to do so.
Aside of that VDSO data has become a dump ground for various mechanisms
and fail to provide a clear separation of the functionalities.
Clean this up by:
* consolidating the VDSO page data by getting rid of architecture
specific warts especially in x86 and PowerPC.
* removing the last includes of header files which are pulling in other
headers outside of the VDSO namespace.
* seperating timekeeping and other VDSO data accordingly.
Further consolidation of the VDSO page handling is done in subsequent
changes scheduled for the next merge window.
This also lays the ground for expanding the VDSO time getters for
independent PTP clocks in a generic way without making every architecture
add support seperately.

A set of updates for the interrupt subsystem:
- Tree wide:
* Make nr_irqs static to the core code and provide accessor functions
to remove existing and prevent future aliasing problems with local
variables or function arguments of the same name.
- Core code:
* Prevent freeing an interrupt in the devres code which is not managed
by devres in the first place.
* Use seq_put_decimal_ull_width() for decimal values output in
/proc/interrupts which increases performance significantly as it
avoids parsing the format strings over and over.
* Optimize raising the timer and hrtimer soft interrupts by using the
'set bit only' variants instead of the combined version which checks
whether ksoftirqd should be woken up. The latter is a pointless
exercise as both soft interrupts are raised in the context of the
timer interrupt and therefore never wake up ksoftirqd.
* Delegate timer/hrtimer soft interrupt processing to a dedicated thread
on RT.
Timer and hrtimer soft interrupts are always processed in ksoftirqd
on RT enabled kernels. This can lead to high latencies when other
soft interrupts are delegated to ksoftirqd as well.
The separate thread allows to run them seperately under a RT
scheduling policy to reduce the latency overhead.
- Drivers:
* New drivers or extensions of existing drivers to support Renesas
RZ/V2H(P), Aspeed AST27XX, T-HEAD C900 and ATMEL sam9x7 interrupt
chips
* Support for multi-cluster GICs on MIPS.
MIPS CPUs can come with multiple CPU clusters, where each CPU cluster
has its own GIC (Generic Interrupt Controller). This requires to
access the GIC of a remote cluster through a redirect register block.
This is encapsulated into a set of helper functions to keep the
complexity out of the actual code paths which handle the GIC details.
* Support for encrypted guests in the ARM GICV3 ITS driver
The ITS page needs to be shared with the hypervisor and therefore
must be decrypted.
* Small cleanups and fixes all over the place

- Fair scheduler:
- Optimize the PLACE_LAG when se->vlag is zero (Huang Shijie)
- Idle loop:
Optimize the generic idle loop by removing unnecessary
memory barrier (Zhongqiu Han)
- RSEQ:
- Improve cache locality of RSEQ concurrency IDs for
intermittent workloads (Mathieu Desnoyers)
- Waitqueues:
- Make wake_up_{bit,var} less fragile (Neil Brown)
- PSI:
- Pass enqueue/dequeue flags to psi callbacks directly (Johannes Weiner)
- Preparatory patches for proxy execution:
- core: Add move_queued_task_locked helper (Connor O'Brien)
- core: Consolidate pick_*_task to task_is_pushable helper (Connor O'Brien)
- core: Split out __schedule() deactivate task logic into a helper (John Stultz)
- core: Split scheduler and execution contexts (Peter Zijlstra)
- locking/mutex: Make mutex::wait_lock irq safe (Juri Lelli)
- locking/mutex: Expose __mutex_owner() (Juri Lelli)

arm64 updates for 6.13:
* Support for running Linux in a protected VM under the Arm Confidential
Compute Architecture (CCA)
* Guarded Control Stack user-space support. Current patches follow the
x86 ABI of implicitly creating a shadow stack on clone(). Subsequent
patches (already on the list) will add support for clone3() allowing
finer-grained control of the shadow stack size and placement from libc
* AT_HWCAP3 support (not running out of HWCAP2 bits yet but we are
getting close with the upcoming dpISA support)
* Other arch features:
- In-kernel use of the memcpy instructions, FEAT_MOPS (previously only
exposed to user; uaccess support not merged yet)
- MTE: hugetlbfs support and the corresponding kselftests
- Optimise CRC32 using the PMULL instructions
- Support for FEAT_HAFT enabling ARCH_HAS_NONLEAF_PMD_YOUNG
- Optimise the kernel TLB flushing to use the range operations
- POE/pkey (permission overlays): further cleanups after bringing the
signal handler in line with the x86 behaviour for 6.12
* arm64 perf updates:
- Support for the NXP i.MX91 PMU in the existing IMX driver
- Support for Ampere SoCs in the Designware PCIe PMU driver
- Support for Marvell's 'PEM' PCIe PMU present in the 'Odyssey' SoC
- Support for Samsung's 'Mongoose' CPU PMU
- Support for PMUv3.9 finer-grained userspace counter access control
- Switch back to platform_driver::remove() now that it returns 'void'
- Add some missing events for the CXL PMU driver
* Miscellaneous arm64 fixes/cleanups:
- Page table accessors cleanup: type updates, drop unused macros,
reorganise arch_make_huge_pte() and clean up pte_mkcont(), sanity
check addresses before runtime P4D/PUD folding
- Command line override for ID_AA64MMFR0_EL1.ECV (advertising the
FEAT_ECV for the generic timers) allowing Linux to boot with
firmware deployments that don't set SCTLR_EL3.ECVEn
- ACPI/arm64: tighten the check for the array of platform timer
structures and adjust the error handling procedure in
gtdt_parse_timer_block()
- Optimise the cache flush for the uprobes xol slot (skip if no
change) and other uprobes/kprobes cleanups
- Fix the context switching of tpidrro_el0 when kpti is enabled
- Dynamic shadow call stack fixes
- Sysreg updates
- Various arm64 kselftest improvements

s390 updates for 6.13 merge window
- Add firmware sysfs interface which allows user space to retrieve the dump
area size of the machine
- Add 'measurement_chars_full' CHPID sysfs attribute to make the complete
associated Channel-Measurements Characteristics Block available
- Add virtio-mem support
- Move gmap aka KVM page fault handling from the main fault handler to KVM
code. This is the first step to make s390 KVM page fault handling similar
to other architectures. With this first step the main fault handler does
not have any special handling anymore, and therefore convert it to
support LOCK_MM_AND_FIND_VMA
- With gcc 14 s390 support for flag output operand support for inline
assemblies was added. This allows for several optimizations
- Provide a cmpxchg inline assembly which makes use of this, and provide
all variants of arch_try_cmpxchg() so that the compiler can generate
slightly better code
- Convert a few cmpxchg() loops to try_cmpxchg() loops
- Similar to x86 add a CC_OUT() helper macro (and other macros), and
convert all inline assemblies to make use of them, so that depending on
compiler version better code can be generated
- List installed host-key hashes in sysfs if the machine supports the Query
Ultravisor Keys UVC
- Add 'Retrieve Secret' ioctl which allows user space in protected
execution guests to retrieve previously stored secrets from the
Ultravisor
- Add pkey-uv module which supports the conversion of Ultravisor
retrievable secrets to protected keys
- Extend the existing paes cipher to exploit the full AES-XTS hardware
acceleration introduced with message-security assist extension 10
- Convert hopefully all sysfs show functions to use sysfs_emit() so that
the constant flow of such patches stop
- For PCI devices make use of the newly added Topology ID attribute to
enable whole card multi-function support despite the change to PCHID per
port. Additionally improve the overall robustness and usability of
the multifunction support
- Various other small improvements, fixes, and cleanups
