ipv6: use inet->cork.fl.u.ip6 and np->final in ip6_datagram_dst_update()
Get rid of @fl6 and &final variables in ip6_datagram_dst_update(). Use instead inet->cork.fl.u.ip6 and np->final so that a stack canary is no longer needed.

soc: driver updates for 7.0
There are are a number of to firmware drivers, in particular the TEE
subsystem:
- a bus callback for TEE firmware that device drivers can register to
- sysfs support for tee firmware information
- minor updates to platform specific TEE drivers for AMD, NXP, Qualcomm
and the generic optee driver
- ARM SCMI firmware refactoring to improve the protocol discover
among other fixes and cleanups
- ARM FF-A firmware interoperability improvements
The reset controller and memory controller subsystems gain support for
additional hardware platforms from Mediatek, Renesas, NXP, Canaan and
SpacemiT.
Most of the other changes are for random drivers/soc code. Among
a number of cleanups and newly added hardware support, including:
- Mediatek MT8196 DVFS power management and mailbox support
- Qualcomm SCM firmware and MDT loader refactoring, as part of
the new Glymur platform support.
- NXP i.MX9 System Manager firmware support for accessing the
syslog
- Minor updates for TI, Renesas, Samsung, Apple, Marvell and AMD
SoCs.

From Qingfang Deng. 5) Recent net-next update extended existing test for ip6ip6 tunnels, add the required /config entry. Test still passed by accident because the previous tests network setup gets re-used, so also update the test so it will fail in case the ip6ip6 tunnel interface cannot be added. 6) Fix 'nft get element mytable myset { 1.2.3.4 }' on big endian platforms, this was broken since code was added in v5.1. 7) Fix nf_tables counter reset support on 32bit platforms, where counter reset may cause huge values to appear due to wraparound. Broken since reset feature was added in v6.11. From Anders Grahn. 8-11) update nf_tables rbtree set type to detect partial operlaps.

xfrm: reduce struct sec_path size
The mentioned struct has an hole and uses unnecessary wide type to
store MAC length and indexes of very small arrays.
It's also embedded into the skb_extensions, and the latter, due
to recent CAN changes, may exceeds the 192 bytes mark (3 cachelines
on x86_64 arch) on some reasonable configurations.
Reordering and the sec_path fields, shrinking xfrm_offload.orig_mac_len
to 16 bits and xfrm_offload.{len,olen,verified_cnt} to u8, we can save
16 bytes and keep skb_extensions size under control.
Before:
struct sec_path {
int len;
int olen;
int verified_cnt;
/* XXX 4 bytes hole, try to pack */$
struct xfrm_state * xvec[6];
struct xfrm_offload ovec[1];
/* size: 88, cachelines: 2, members: 5 */
/* sum members: 84, holes: 1, sum holes: 4 */
/* last cacheline: 24 bytes */
};
After:
struct sec_path {
struct xfrm_state * xvec[6];
struct xfrm_offload ovec[1];
/* typedef u8 -> __u8 */ unsigned char len;
/* typedef u8 -> __u8 */ unsigned char olen;
/* typedef u8 -> __u8 */ unsigned char verified_cnt;
/* size: 72, cachelines: 2, members: 5 */
/* padding: 1 */
/* last cacheline: 8 bytes */

bnxt_en: Refactor bnxt_need_reserve_rings()
bnxt_need_reserve_rings() checks 6 ring resources against the reserved values to determine if a new reservation is needed. Factor out the code to collect the total resources into a new helper function bnxt_get_total_resources() to make the code cleaner and easier to read. Instead of individual scalar variables, use the struct bnxt_hw_rings to hold all the ring resources. Using the struct, hwr.cp replaces the nq variable and the chip specific hwr.cp_p5 replaces cp on newer chips. There is no change in behavior. This will make it easier to check the RSS context resource in the next patch.

mptcp: allow overridden write_space to be invoked
Future extensions with psock will override their own sk->sk_write_space callback. This patch ensures that the overridden sk_write_space can be invoked by MPTCP. INDIRECT_CALL is used to keep the default path optimised. Note that sk->sk_write_space was never called directly with MPTCP sockets, so changing it to sk_stream_write_space in the init, and using it from mptcp_write_space() is not supposed to change the current behaviour. This patch is shared early to ease discussions around future RFC and avoid confusions with this "fix" that is needed for different future extensions.

Merge branch 'net-netconsole-convert-to-nbcon-console-infrastructure'
Breno Leitao says:
====================
net: netconsole: convert to NBCON console infrastructure
This series adds support for the nbcon (new buffer console) infrastructure
to netconsole, enabling lock-free, priority-based console operations that
are safer in crash scenarios.
The implementation is introduced in three steps:
0) Extend printk to expose CPU and taskname (task->comm) where the
printk originated from. (Thanks John and Petr for the support in
getting this done)
1) Refactor the message fragmentation logic into a reusable helper function
2) Extend nbcon support to non-extended (basic) consoles using the same
infrastructure.
The initial discussion about it appeared a while ago in [1], in order to
solve Mike's HARDIRQ-safe -> HARDIRQ-unsafe lock order warning, and the root
cause is that some hosts were calling IRQ unsafe locks from inside console
lock.
At that time, we didn't have the CON_NBCON_ATOMIC_UNSAFE yet. John
kindly implemented CON_NBCON_ATOMIC_UNSAFE in

netconsole: Use printk context for CPU and task information
Use the CPU and task name captured at printk() time from nbcon_write_context instead of querying the current execution context. This provides accurate information about where the message originated, rather than where netconsole happens to be running. For CPU, use wctxt->cpu instead of raw_smp_processor_id(). For taskname, use wctxt->comm directly which contains the task name captured at printk time. This change ensures netconsole outputs reflect the actual context that generated the log message, which is especially important when the console driver runs asynchronously in a dedicated thread.

netconsole: convert to NBCON console infrastructure
Convert netconsole from the legacy console API to the NBCON framework.
NBCON provides threaded printing which unblocks printk()s and flushes in
a thread, decoupling network TX from printk() when netconsole is
in use.
Since netconsole relies on the network stack which cannot safely operate
from all atomic contexts, mark both consoles with
CON_NBCON_ATOMIC_UNSAFE. (See discussion in [1])
CON_NBCON_ATOMIC_UNSAFE restricts write_atomic() usage to emergency
scenarios (panic) where regular messages are sent in threaded mode.
Implementation changes:
- Unify write_ext_msg() and write_msg() into netconsole_write()
- Add device_lock/device_unlock callbacks to manage target_list_lock
- Use nbcon_enter_unsafe()/nbcon_exit_unsafe() around network
operations.
- If nbcon_enter_unsafe() fails, just return given netconsole lost
the ownership of the console.
- Set write_thread and write_atomic callbacks (both use same function)

netconsole: extract message fragmentation into send_msg_udp()
Extract the message fragmentation logic from write_msg() into a dedicated send_msg_udp() function. This improves code readability and prepares for future enhancements. The new send_msg_udp() function handles splitting messages that exceed MAX_PRINT_CHUNK into smaller fragments and sending them sequentially. This function is placed before send_ext_msg_udp() to maintain a logical ordering of related functions. No functional changes - this is purely a refactoring commit.

printk: Add execution context (task name/CPU) to printk_info
Extend struct printk_info to include the task name, pid, and CPU number where printk messages originate. This information is captured at vprintk_store() time and propagated through printk_message to nbcon_write_context, making it available to nbcon console drivers. This is useful for consoles like netconsole that want to include execution context in their output, allowing correlation of messages with specific tasks and CPUs regardless of where the console driver actually runs. The feature is controlled by CONFIG_PRINTK_EXECUTION_CTX, which is automatically selected by CONFIG_NETCONSOLE_DYNAMIC. When disabled, the helper functions compile to no-ops with no overhead.

configfs-tsm-report: tdx_guest: Increase Quote buffer size to 128KB
Intel platforms are transitioning from traditional SGX-based attestation toward DICE-based attestation as part of a broader move toward open and standardized attestation models. DICE enables layered and extensible attestation, where evidence is accumulated across multiple boot stages. With SGX-based attestation, Quote sizes are typically under 8KB, as the payload consists primarily of Quote data and a small certificate bundle. Existing TDX guest code sizes the Quote buffer accordingly. DICE-based attestation produces significantly larger Quotes due to the inclusion of evidence (certificate chains) from multiple boot layers. The cumulative Quote size can reach approximately 100KB. Increase GET_QUOTE_BUF_SIZE to 128KB to ensure sufficient buffer capacity for DICE-based Quote payloads.

configfs-tsm-report: Increase TSM_REPORT_OUTBLOB_MAX to 16MB
Confidential Computing (CoCo) attestation is evolving toward standardized models such as DICE (Device Identifier Composition Engine) and Post-Quantum Cryptography (PQC), which rely on layered certificate chains and larger cryptographic signatures. A typical PQC certificate can range from 5KB to 15KB, and DICE-based architectures accumulate these certificates across multiple boot stages. In such configurations, the total attestation evidence can reach several megabytes, exceeding the current 32KB limit. Increase TSM_REPORT_OUTBLOB_MAX to 16MB to accommodate these larger certificate chains. This provides sufficient headroom to handle evolving requirements without requiring frequent updates to the limit. TSM_REPORT_OUTBLOB_MAX is used by the configfs read interface to cap the maximum allowed binary blob size for outblob, auxblob and manifestblob attributes. Hence, the per-open-file worst case memory allocation increases from 32KB to 16MB. Multiple concurrent readers multiply this cost (e.g., N readers of an M-byte blob incur NxM bytes of vmalloc-backed memory). However, allocations are performed on demand and remain proportional to the actual blob length, not the configured maximum.

configfs-tsm-report: Document size limits for outblob attributes
The configfs-tsm-report interface can fail with -EFBIG when the attestation report generated by a TSM provider exceeds internal maximums (TSM_REPORT_OUTBLOB_MAX). However, this error condition and its handling are not currently documented in the ABI. Userspace tools need to understand how to interpret various error conditions when reading attestation reports. Document that reads fail with -EFBIG when reports exceed size limits, with guidance on how to resolve them.

Updates for the VDSO subsystem:
- Provide the missing 64-bit variant of clock_getres()
This allows the extension of CONFIG_COMPAT_32BIT_TIME to the vDSO and
finally the removal of 32-bit time types from the kernel and UAPI.
- Remove the useless and broken getcpu_cache from the VDSO
The intention was to provide a trivial way to retrieve the CPU number from
the VDSO, but as the VDSO data is per process there is no way to make it
work.
- Switch get/put_unaligned() from packed struct to memcpy()
The packed struct violates strict aliasing rules which requires to pass
-fno-strict-aliasing to the compiler. As this are scalar values
__builtin_memcpy() turns them into simple loads and stores
- Use __typeof_unqual__() for __unqual_scalar_typeof()
The get/put_unaligned() changes triggered a new sparse warning when __beNN
types are used with get/put_unaligned() as sparse builds add a special
'bitwise' attribute to them which prevents sparse to evaluate the Generic
in __unqual_scalar_typeof().
Newer sparse versions support __typeof_unqual__() which avoids the problem,
but requires a recent sparse install. So this adds a sanity check to sparse
builds, which validates that sparse is available and capable of handling it.
- Force inline __cvdso_clock_getres_common()
Compilers sometimes un-inline agressively, which results in function call
overhead and problems with automatic stack variable initialization.
Interestingly enough the force inlining results in smaller code than the
un-inlined variant produced by GCC when optimizing for size.

Updates for the [PCI] MSI subsystem:
- Add interrupt redirection infrastructure
Some PCI controllers use a single demultiplexing interrupt for the MSI
interrupts of subordinate devices.
This prevents setting the interrupt affinity of device interrupts, which
causes device interrupts to be delivered to a single CPU. That obviously is
counterproductive for multi-queue devices and interrupt balancing.
To work around this limitation the new infrastructure installs a dummy
irq_set_affinity() callback which captures the affinity mask and picks a
redirection target CPU out of the mask.
When the PCI controller demultiplexes the interrupts it invokes a new
handling function in the core, which either runs the interrupt handler in
the context of the target CPU or delegates it to irq_work on the target CPU.
- Utilize the interrupt redirection mechanism in the PCI DWC host controller
driver.
This allows affinity control for the subordinate device MSI interrupts
instead of being randomly executed on the CPU which runs the demultiplex
handler.
- Replace the binary 64-bit MSI flag with a DMA mask
Some PCI devices have PCI_MSI_FLAGS_64BIT in the MSI capability, but
implement less than 64 address bits. This breaks on platforms where such a
device is assigned an MSI address higher than what's supported.
With the binary 64-bit flag there is no other choice than disabling 64-bit
MSI support which leaves the device disfunctional.
By using a DMA mask the address limit of a device can be described
correctly which provides support for the above scenario.
- Make use of the DMA mask based address limit in the hda/intel and radeon
drivers to enable them on affected platforms.
- The usual small cleanups and improvements

Updates for interrupt chip drivers:
- Add support for the Renesas RZ/V2N SoC
- Add a new driver for the Renesas RZ/[TN]2H SoCs
- Preserve the register state of the RISCV APLIC interrupt controller accross
suspend/resume
- Reinitialize the RISCV IMSIC registers after suspend/resume
- Make the various Loongson interrupt chip drivers 32/64-bit aware
- Handle the number of hardware interrupts in the SIFIVE PLIC driver
correctly.
The hardware interrupt 0 is reserved which resulted in inconsistent
accounting. That went unnoticed as the off by one is only noticable when
the number of device interrupts is a multiple of 32.
- The usual device tree updates, cleanups and improvements all over the place.

Updates for the interrupt core subsystem:
- Remove the interrupt timing infrastructure
This was added seven years ago to be used for power management purposes, but
that integration never happened.
- Clean up the remaining setup_percpu_irq() users
The memory allocator is available when interrupts can be requested so there
is not need for static irq_action. Move the remaining users to
request_percpu_irq() and delete the historical cruft.
- Warn when interrupt flag inconsistencies are detected in request*_irq().
Inconsistent flags can lead to hard to diagnose malfunction. The fallout of
this new warning has been addressed in next and the fixes are coming in via
the maintainer trees and the tip irq/cleanup pull requests.
- Invoke affinity notifier when CPU hotplug breaks affinity
Otherwise the code using the notifier misses the affinity change and
operates on stale information.
- The usual cleanups and improvements

A series of treewide cleanups to ensure interrupt request consistency.
- Add the missing IRQF_COND_ONESHOT flag to devm_request_irq()
This is inconsistent vs. request_irq() and causes the same issues which
where addressed with the introduction of this flag
- Cleanup IRQF_ONESHOT and IRQF_NO_THREAD usage
Quite some drivers have inconsistent interrupt request flags related to
interrupt threading namely IRQF_ONESHOT and IRQF_NO_THREAD. This leads to
warnings and/or malfunction when forced interrupt threading is enabled.
- Remove stub primary (hard interrupt) handlers
A bunch of drivers implement a stub primary (hard interrupt) handler which
just returns IRQ_WAKE_THREAD. The same functionality is provided by the
core code when the primary handler argument of request_thread_irq() is set
to NULL.

Scheduler changes for v7.0:
Scheduler Kconfig space updates:
- Further consolidate configurable preemption modes: reduce
the number of architectures that are allowed to offer
PREEMPT_NONE and PREEMPT_VOLUNTARY, reducing the number
of preemption models from four to just two: 'full' and 'lazy'
on up-to-date architectures (arm64, loongarch, powerpc,
riscv, s390, x86).
None and voluntary are only available as legacy features
on platforms that don't implement lazy preemption yet,
or which don't even support preemption.
The goal is to eventually remove cond_resched() and
voluntary preemption altogether.
(Peter Zijlstra)
RSEQ based 'scheduler time slice extension' support:
This allows a thread to request a time slice extension when it
enters a critical section to avoid contention on a resource when
the thread is scheduled out inside of the critical section.
- Add fields and constants for time slice extension
- Provide static branch for time slice extensions
- Add statistics for time slice extensions
- Add prctl() to enable time slice extensions
- Implement sys_rseq_slice_yield()
- Implement syscall entry work for time slice extensions
- Implement time slice extension enforcement timer
- Reset slice extension when scheduled
- Implement rseq_grant_slice_extension()
- entry: Hook up rseq time slice extension

- Allow registering RSEQ with slice extension
- Move slice_ext_nsec to debugfs
- Lower default slice extension
- selftests/rseq: Add rseq slice histogram script
(Peter Zijlstra)
Scheduler performance/scalability improvements:
- Update rq->avg_idle when a task is moved to an idle CPU,
which improves the scalability of various workloads.
(Shubhang Kaushik)
- Reorder fields in 'struct rq' for better caching
(Blake Jones)
- Fair scheduler SMP NOHZ balancing code speedups:
- Move checking for nohz cpus after time check
- Change likelyhood of nohz.nr_cpus
- Remove nohz.nr_cpus and use weight of cpumask instead
(Shrikanth Hegde)
- Avoid false sharing for sched_clock_irqtime (Wangyang Guo)
- Drop useless cpumask_empty() in find_energy_efficient_cpu()

(Yury Norov)
DL scheduler updates:
- Add a deadline server for sched_ext tasks (by Andrea Righi and
Joel Fernandes, with fixes by Peter Zijlstra)
RT scheduler updates:
- Skip currently executing CPU in rto_next_cpu() (Chen Jinghuang)
Entry code updates and performance improvements, which is part of the
scheduler tree in this cycle due to interdependencies with the RSEQ
based time slice extension work:
- Remove unused syscall argument from syscall_trace_enter()
- Rework syscall_exit_to_user_mode_work() for architecture reuse
- Add arch_ptrace_report_syscall_entry/exit()
- Inline syscall_exit_work() and syscall_trace_enter()
(Jinjie Ruan)
Scheduler core updates:
- Rework sched_class::wakeup_preempt() and rq_modified_*()
- Avoid rq->lock bouncing in sched_balance_newidle()
- Rename rcu_dereference_check_sched_domain() =>
rcu_dereference_sched_domain()

(Peter Zijlstra)
Fair scheduler updates/refactoring:

- Change rcu_dereference_check_sched_domain() to rcu-sched
- Switch to rcu_dereference_all()
- Remove superfluous rcu_read_lock()
- Limit hrtick work
(Peter Zijlstra)
- Join two #ifdef CONFIG_FAIR_GROUP_SCHED blocks
- Clean up comments in 'struct cfs_rq'
- Separate se->vlag from se->vprot
- Rename cfs_rq::avg_load to cfs_rq::sum_weight
- Rename cfs_rq::avg_vruntime to ::sum_w_vruntime & helper functions
- Introduce and use the vruntime_cmp() and vruntime_op() wrappers
for wrapped-signed aritmetics

Locking updates for v6.20:
Lock debugging:
- Implement compiler-driven static analysis locking context
checking, using the upcoming Clang 22 compiler's context
analysis features. (Marco Elver)
We removed Sparse context analysis support, because prior to
removal even a defconfig kernel produced 1,700+ context
tracking Sparse warnings, the overwhelming majority of which
are false positives. On an allmodconfig kernel the number of
false positive context tracking Sparse warnings grows to
over 5,200... On the plus side of the balance actual locking
bugs found by Sparse context analysis is also rather ... sparse:
I found only 3 such commits in the last 3 years. So the
rate of false positives and the maintenance overhead is
rather high and there appears to be no active policy in
place to achieve a zero-warnings baseline to move the
annotations & fixers to developers who introduce new code.
Clang context analysis is more complete and more aggressive
in trying to find bugs, at least in principle. Plus it has
a different model to enabling it: it's enabled subsystem by
subsystem, which results in zero warnings on all relevant
kernel builds (as far as our testing managed to cover it).
Which allowed us to enable it by default, similar to other
compiler warnings, with the expectation that there are no
warnings going forward. This enforces a zero-warnings baseline
on clang-22+ builds. (Which are still limited in distribution,
admittedly.)
Hopefully the Clang approach can lead to a more maintainable
zero-warnings status quo and policy, with more and more
subsystems and drivers enabling the feature. Context tracking
can be enabled for all kernel code via WARN_CONTEXT_ANALYSIS_ALL=y
(default disabled), but this will generate a lot of false positives.
( Having said that, Sparse support could still be added back,
if anyone is interested - the removal patch is still
relatively straightforward to revert at this stage. )
Rust integration updates: (Alice Ryhl, Fujita Tomonori, Boqun Feng)
- Add support for Atomic<i8/i16/bool> and replace most Rust native
AtomicBool usages with Atomic<bool>
- Clean up LockClassKey and improve its documentation
- Add missing Send and Sync trait implementation for SetOnce
- Make ARef Unpin as it is supposed to be
- Add __rust_helper to a few Rust helpers as a preparation for
helper LTO
- Inline various lock related functions to avoid additional
function calls.
WW mutexes:
- Extend ww_mutex tests and other test-ww_mutex updates (John Stultz)
Misc fixes and cleanups:
- rcu: Mark lockdep_assert_rcu_helper() __always_inline
(Arnd Bergmann)
- locking/local_lock: Include more missing headers (Peter Zijlstra)
- seqlock: fix scoped_seqlock_read kernel-doc (Randy Dunlap)
- rust: sync: Replace `kernel::c_str!` with C-Strings
(Tamir Duberstein)

Pull locking updates from Ingo Molnar:
"Lock debugging:
- Implement compiler-driven static analysis locking context checking,
using the upcoming Clang 22 compiler's context analysis features
(Marco Elver)
We removed Sparse context analysis support, because prior to
removal even a defconfig kernel produced 1,700+ context tracking
Sparse warnings, the overwhelming majority of which are false
positives. On an allmodconfig kernel the number of false positive
context tracking Sparse warnings grows to over 5,200... On the plus
side of the balance actual locking bugs found by Sparse context
analysis is also rather ... sparse: I found only 3 such commits in
the last 3 years. So the rate of false positives and the
maintenance overhead is rather high and there appears to be no
active policy in place to achieve a zero-warnings baseline to move
the annotations & fixers to developers who introduce new code.
Clang context analysis is more complete and more aggressive in
trying to find bugs, at least in principle. Plus it has a different
model to enabling it: it's enabled subsystem by subsystem, which
results in zero warnings on all relevant kernel builds (as far as
our testing managed to cover it). Which allowed us to enable it by
default, similar to other compiler warnings, with the expectation
that there are no warnings going forward. This enforces a
zero-warnings baseline on clang-22+ builds (Which are still limited
in distribution, admittedly)
Hopefully the Clang approach can lead to a more maintainable
zero-warnings status quo and policy, with more and more subsystems
and drivers enabling the feature. Context tracking can be enabled
for all kernel code via WARN_CONTEXT_ANALYSIS_ALL=y (default
disabled), but this will generate a lot of false positives.
( Having said that, Sparse support could still be added back,
if anyone is interested - the removal patch is still
relatively straightforward to revert at this stage. )
Rust integration updates: (Alice Ryhl, Fujita Tomonori, Boqun Feng)
- Add support for Atomic<i8/i16/bool> and replace most Rust native
AtomicBool usages with Atomic<bool>
- Clean up LockClassKey and improve its documentation
- Add missing Send and Sync trait implementation for SetOnce
- Make ARef Unpin as it is supposed to be
- Add __rust_helper to a few Rust helpers as a preparation for
helper LTO
- Inline various lock related functions to avoid additional function
calls
WW mutexes:
- Extend ww_mutex tests and other test-ww_mutex updates (John
Stultz)
Misc fixes and cleanups:
- rcu: Mark lockdep_assert_rcu_helper() __always_inline (Arnd
Bergmann)
- locking/local_lock: Include more missing headers (Peter Zijlstra)
- seqlock: fix scoped_seqlock_read kernel-doc (Randy Dunlap)
- rust: sync: Replace `kernel::c_str!` with C-Strings (Tamir
Duberstein)"
