It has been a relatively busy cycle for docs, especially the build system:
- The Perl kernel-doc script was added to 2.3.52pre1 just after the turn of
the millennium. Over the following 25 years, it accumulated a vast
amount of cruft, all in a language few people want to deal with anymore.
Mauro's Python replacement in 6.16 faithfully reproduced all of the cruft
in the hope of avoiding regressions. Now that we have a more reasonable
code base, though, we can work on cleaning it up; many of the changes
this time around are toward that end.
- A reorganization of the ext4 docs into the usual TOC format.
- Various Chinese translations and updates.
- A new script from Mauro to help with docs-build testing.
- A new document for linked lists
- A sweep through MAINTAINERS fixing broken GitHub git:// repository links.
...and lots of fixes and updates.

Merge tag 'docs-6.17' of git://git.lwn.net/linux
Pull documentation updates from Jonathan Corbet:
"It has been a relatively busy cycle for docs, especially the build
system:
- The Perl kernel-doc script was added to 2.3.52pre1 just after the
turn of the millennium. Over the following 25 years, it accumulated
a vast amount of cruft, all in a language few people want to deal
with anymore. Mauro's Python replacement in 6.16 faithfully
reproduced all of the cruft in the hope of avoiding regressions.
Now that we have a more reasonable code base, though, we can work
on cleaning it up; many of the changes this time around are toward
that end.
- A reorganization of the ext4 docs into the usual TOC format.
- Various Chinese translations and updates.
- A new script from Mauro to help with docs-build testing.
- A new document for linked lists
- A sweep through MAINTAINERS fixing broken GitHub git:// repository
links.
...and lots of fixes and updates"

ARM:
- Host driver for GICv5, the next generation interrupt controller for arm64, including support for interrupt routing, MSIs, interrupt translation and wired interrupts. - Use FEAT_GCIE_LEGACY on GICv5 systems to virtualize GICv3 VMs on GICv5 hardware, leveraging the legacy VGIC interface. - Userspace control of the 'nASSGIcap' GICv3 feature, allowing userspace to disable support for SGIs w/o an active state on hardware that previously advertised it unconditionally. - Map supporting endpoints with cacheable memory attributes on systems with FEAT_S2FWB and DIC where KVM no longer needs to perform cache maintenance on the address range. - Nested support for FEAT_RAS and FEAT_DoubleFault2, allowing the guest hypervisor to inject external aborts into an L2 VM and take traps of masked external aborts to the hypervisor. - Convert more system register sanitization to the config-driven implementation. - Fixes to the visibility of EL2 registers, namely making VGICv3 system registers accessible through the VGIC device instead of the ONE_REG vCPU ioctls. - Various cleanups and minor fixes. LoongArch: - Add stat information for in-kernel irqchip - Add tracepoints for CPUCFG and CSR emulation exits - Enhance in-kernel irqchip emulation - Various cleanups. RISC-V: - Enable ring-based dirty memory tracking - Improve perf kvm stat to report interrupt events - Delegate illegal instruction trap to VS-mode - MMU improvements related to upcoming nested virtualization s390x - Fixes x86: - Add CONFIG_KVM_IOAPIC for x86 to allow disabling support for I/O APIC, PIC, and PIT emulation at compile time. - Share device posted IRQ code between SVM and VMX and harden it against bugs and runtime errors. - Use vcpu_idx, not vcpu_id, for GA log tag/metadata, to make lookups O(1) instead of O(n). - For MMIO stale data mitigation, track whether or not a vCPU has access to (host) MMIO based on whether the page tables have MMIO pfns mapped; using VFIO is prone to false negatives - Rework the MSR interception code so that the SVM and VMX APIs are more or less identical. - Recalculate all MSR intercepts from scratch on MSR filter changes, instead of maintaining shadow bitmaps. - Advertise support for LKGS (Load Kernel GS base), a new instruction that's loosely related to FRED, but is supported and enumerated independently. - Fix a user-triggerable WARN that syzkaller found by setting the vCPU in INIT_RECEIVED state (aka wait-for-SIPI), and then putting the vCPU into VMX Root Mode (post-VMXON). Trying to detect every possible path leading to architecturally forbidden states is hard and even risks breaking userspace (if it goes from valid to valid state but passes through invalid states), so just wait until KVM_RUN to detect that the vCPU state isn't allowed. - Add KVM_X86_DISABLE_EXITS_APERFMPERF to allow disabling interception of APERF/MPERF reads, so that a "properly" configured VM can access APERF/MPERF. This has many caveats (APERF/MPERF cannot be zeroed on vCPU creation or saved/restored on suspend and resume, or preserved over thread migration let alone VM migration) but can be useful whenever you're interested in letting Linux guests see the effective physical CPU frequency in /proc/cpuinfo. - Reject KVM_SET_TSC_KHZ for vm file descriptors if vCPUs have been created, as there's no known use case for changing the default frequency for other VM types and it goes counter to the very reason why the ioctl was added to the vm file descriptor. And also, there would be no way to make it work for confidential VMs with a "secure" TSC, so kill two birds with one stone. - Dynamically allocation the shadow MMU's hashed page list, and defer allocating the hashed list until it's actually needed (the TDP MMU doesn't use the list). - Extract many of KVM's helpers for accessing architectural local APIC state to common x86 so that they can be shared by guest-side code for Secure AVIC. - Various cleanups and fixes. x86 (Intel): - Preserve the host's DEBUGCTL.FREEZE_IN_SMM when running the guest. Failure to honor FREEZE_IN_SMM can leak host state into guests. - Explicitly check vmcs12.GUEST_DEBUGCTL on nested VM-Enter to prevent L1 from running L2 with features that KVM doesn't support, e.g. BTF. x86 (AMD): - WARN and reject loading kvm-amd.ko instead of panicking the kernel if the nested SVM MSRPM offsets tracker can't handle an MSR (which is pretty much a static condition and therefore should never happen, but still). - Fix a variety of flaws and bugs in the AVIC device posted IRQ code. - Inhibit AVIC if a vCPU's ID is too big (relative to what hardware supports) instead of rejecting vCPU creation. - Extend enable_ipiv module param support to SVM, by simply leaving IsRunning clear in the vCPU's physical ID table entry. - Disable IPI virtualization, via enable_ipiv, if the CPU is affected by erratum #1235, to allow (safely) enabling AVIC on such CPUs. - Request GA Log interrupts if and only if the target vCPU is blocking, i.e. only if KVM needs a notification in order to wake the vCPU. - Intercept SPEC_CTRL on AMD if the MSR shouldn't exist according to the vCPU's CPUID model. - Accept any SNP policy that is accepted by the firmware with respect to SMT and single-socket restrictions. An incompatible policy doesn't put the kernel at risk in any way, so there's no reason for KVM to care. - Drop a superfluous WBINVD (on all CPUs!) when destroying a VM and use WBNOINVD instead of WBINVD when possible for SEV cache maintenance. - When reclaiming memory from an SEV guest, only do cache flushes on CPUs that have ever run a vCPU for the guest, i.e. don't flush the caches for CPUs that can't possibly have cache lines with dirty, encrypted data. Generic: - Rework irqbypass to track/match producers and consumers via an xarray instead of a linked list. Using a linked list leads to O(n^2) insertion times, which is hugely problematic for use cases that create large numbers of VMs. Such use cases typically don't actually use irqbypass, but eliminating the pointless registration is a future problem to solve as it likely requires new uAPI. - Track irqbypass's "token" as "struct eventfd_ctx *" instead of a "void *", to avoid making a simple concept unnecessarily difficult to understand. - Decouple device posted IRQs from VFIO device assignment, as binding a VM to a VFIO group is not a requirement for enabling device posted IRQs. - Clean up and document/comment the irqfd assignment code. - Disallow binding multiple irqfds to an eventfd with a priority waiter, i.e. ensure an eventfd is bound to at most one irqfd through the entire host, and add a selftest to verify eventfd:irqfd bindings are globally unique. - Add a tracepoint for KVM_SET_MEMORY_ATTRIBUTES to help debug issues related to private <=> shared memory conversions. - Drop guest_memfd's .getattr() implementation as the VFS layer will call generic_fillattr() if inode_operations.getattr is NULL. - Fix issues with dirty ring harvesting where KVM doesn't bound the processing of entries in any way, which allows userspace to keep KVM in a tight loop indefinitely. - Kill off kvm_arch_{start,end}_assignment() and x86's associated tracking, now that KVM no longer uses assigned_device_count as a heuristic for either irqbypass usage or MDS mitigation. Selftests: - Fix a comment typo. - Verify KVM is loaded when getting any KVM module param so that attempting to run a selftest without kvm.ko loaded results in a SKIP message about KVM not being loaded/enabled (versus some random parameter not existing). - Skip tests that hit EACCES when attempting to access a file, and rpint a "Root required?" help message. In most cases, the test just needs to be run with elevated permissions. -----BEGIN PGP SIGNATURE----- iQFIBAABCAAyFiEE8TM4V0tmI4mGbHaCv/vSX3jHroMFAmiKXMgUHHBib256aW5p QHJlZGhhdC5jb20ACgkQv/vSX3jHroMhMQf/QDhC/CP1aGXph2whuyeD2NMqPKiU 9KdnDNST+ftPwjg9QxZ9mTaa8zeVz/wly6XlxD9OQHy+opM1wcys3k0GZAFFEEQm YrThgURdzEZ3nwJZgb+m0t4wjJQtpiFIBwAf7qq6z1VrqQBEmHXJ/8QxGuqO+BNC j5q/X+q6KZwehKI6lgFBrrOKWFaxqhnRAYfW6rGBxRXxzTJuna37fvDpodQnNceN zOiq+avfriUMArTXTqOteJNKU0229HjiPSnjILLnFQ+B3akBlwNG0jk7TMaAKR6q IZWG1EIS9q1BAkGXaw6DE1y6d/YwtXCR5qgAIkiGwaPt5yj9Oj6kRN2Ytw== =j2At -----END PGP SIGNATURE----- Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm Pull kvm updates from Paolo Bonzini: "ARM: - Host driver for GICv5, the next generation interrupt controller for arm64, including support for interrupt routing, MSIs, interrupt translation and wired interrupts - Use FEAT_GCIE_LEGACY on GICv5 systems to virtualize GICv3 VMs on GICv5 hardware, leveraging the legacy VGIC interface - Userspace control of the 'nASSGIcap' GICv3 feature, allowing userspace to disable support for SGIs w/o an active state on hardware that previously advertised it unconditionally - Map supporting endpoints with cacheable memory attributes on systems with FEAT_S2FWB and DIC where KVM no longer needs to perform cache maintenance on the address range - Nested support for FEAT_RAS and FEAT_DoubleFault2, allowing the guest hypervisor to inject external aborts into an L2 VM and take traps of masked external aborts to the hypervisor - Convert more system register sanitization to the config-driven implementation - Fixes to the visibility of EL2 registers, namely making VGICv3 system registers accessible through the VGIC device instead of the ONE_REG vCPU ioctls - Various cleanups and minor fixes LoongArch: - Add stat information for in-kernel irqchip - Add tracepoints for CPUCFG and CSR emulation exits - Enhance in-kernel irqchip emulation - Various cleanups RISC-V: - Enable ring-based dirty memory tracking - Improve perf kvm stat to report interrupt events - Delegate illegal instruction trap to VS-mode - MMU improvements related to upcoming nested virtualization s390x - Fixes x86: - Add CONFIG_KVM_IOAPIC for x86 to allow disabling support for I/O APIC, PIC, and PIT emulation at compile time - Share device posted IRQ code between SVM and VMX and harden it against bugs and runtime errors - Use vcpu_idx, not vcpu_id, for GA log tag/metadata, to make lookups O(1) instead of O(n) - For MMIO stale data mitigation, track whether or not a vCPU has access to (host) MMIO based on whether the page tables have MMIO pfns mapped; using VFIO is prone to false negatives - Rework the MSR interception code so that the SVM and VMX APIs are more or less identical - Recalculate all MSR intercepts from scratch on MSR filter changes, instead of maintaining shadow bitmaps - Advertise support for LKGS (Load Kernel GS base), a new instruction that's loosely related to FRED, but is supported and enumerated independently - Fix a user-triggerable WARN that syzkaller found by setting the vCPU in INIT_RECEIVED state (aka wait-for-SIPI), and then putting the vCPU into VMX Root Mode (post-VMXON).

Using a linked list leads to O(n^2) insertion times, which is hugely problematic for use cases that create large numbers of VMs. Such use cases typically don't actually use irqbypass, but eliminating the pointless registration is a future problem to solve as it likely requires new uAPI - Track irqbypass's "token" as "struct eventfd_ctx *" instead of a "void *", to avoid making a simple concept unnecessarily difficult to understand - Decouple device posted IRQs from VFIO device assignment, as binding a VM to a VFIO group is not a requirement for enabling device posted IRQs - Clean up and document/comment the irqfd assignment code - Disallow binding multiple irqfds to an eventfd with a priority waiter, i.e. ensure an eventfd is bound to at most one irqfd through the entire host, and add a selftest to verify eventfd:irqfd bindings are globally unique - Add a tracepoint for KVM_SET_MEMORY_ATTRIBUTES to help debug issues related to private <=> shared memory conversions - Drop guest_memfd's .getattr() implementation as the VFS layer will call generic_fillattr() if inode_operations.getattr is NULL - Fix issues with dirty ring harvesting where KVM doesn't bound the processing of entries in any way, which allows userspace to keep KVM in a tight loop indefinitely - Kill off kvm_arch_{start,end}_assignment() and x86's associated tracking, now that KVM no longer uses assigned_device_count as a heuristic for either irqbypass usage or MDS mitigation Selftests: - Fix a comment typo - Verify KVM is loaded when getting any KVM module param so that attempting to run a selftest without kvm.ko loaded results in a SKIP message about KVM not being loaded/enabled (versus some random parameter not existing) - Skip tests that hit EACCES when attempting to access a file, and print a "Root required?" help message.

Remove or hide unused tracepoints
Tracepoints take up memory (around 5K per tracepoint) even when they are
unused. Changes are being made to detect when a tracepoint is defined but
unused and a warning is shown at build. But those changes are not yet
ready for inclusion.
- Fix some of the unused tracepoints that it detected
Some tracepoints were removed and others were hidden by config settings
to match the config settings of where they are instantiated. Some
tracepoints were moved into architecture specific code as only one
architecture used them.
- Call the ftrace_test_filter tracepoint in an unreachable if statement
The ftrace_test_filter tracepoint which is defined when ftrace selftests
are configured and is used to test the filter logic, but the tracepoint is
not actually called. It is put into an if statement to not have it get
compiled out, but also not warn for not being used.

Runtime verification changes for 6.17
- Added Linear temporal logic monitors for RT application
Real-time applications may have design flaws causing them to have
unexpected latency. For example, the applications may raise page faults, or
may be blocked trying to take a mutex without priority inheritance.
However, while attempting to implement DA monitors for these real-time
rules, deterministic automaton is found to be inappropriate as the
specification language. The automaton is complicated, hard to understand,
and error-prone.
For these cases, linear temporal logic is found to be more suitable. The
LTL is more concise and intuitive.
- Make printk_deferred() public
The new monitors needed access to printk_deferred(). Make them visible for
the entire kernel.
- Add a vpanic() to allow for va_list to be passed to panic.
- Add rtapp container monitor.
A collection of monitors that check for common problems with real-time
applications that cause unexpected latency.
- Add page fault tracepoints to risc-v
These tracepoints are necessary to for the RV monitor to run on risc-v.
- Fix the behaviour of the rv tool with -s and idle tasks.
- Allow the rv tool to gracefully terminate with SIGTERM
- Adjusts dot2c not to create lines over 100 columns
- Properly order nested monitors in the RV Kconfig file
- Return the registration error in all DA monitor instead of 0
- Update and add new sched collection monitors
Replace tss and sncid monitors with more complete sts:
Not only prove that switches occur in scheduling context and scheduling
needs interrupt disabled but also that each call to the scheduler
disables interrupts to (optionally) switch.
New monitor: nrp
Preemption requires need resched which is cleared by any switch
(includes a non optimal workaround for /nested/ preemptions)
New monitor: sssw
suspension requires setting the task to sleepable and, after the
switch occurs, the task requires a wakeup to come back to runnable
New monitor: opid
waking and need-resched operations occur with interrupts and
preemption disabled or in IRQ without explicitly disabling preemption

ring-buffer changes for v6.17:
- Rewind persistent ring buffer on boot When the persistent ring buffer is being used for live kernel tracing and the system crashes, the tool that is reading the trace may not have recorded the data when the system crashed. Although the persistent ring buffer still has that data, when reading it after a reboot, it will start where it left off. That is, what was read will not be accessible. Instead, on reboot, have the persistent ring buffer restart where the data starts and this will allow the tooling to recover what was lost when the crash occurred. - Remove the ring_buffer_read_prepare_sync() logic Reading the trace file required stopping writing to the ring buffer as the trace file is only an iterator and does not consume what it read. It was originally not safe to read the ring buffer in this mode and required disabling writing. The ring_buffer_read_prepare_sync() logic was used to stop each per_cpu ring buffer, call synchronize_rcu() and then start the iterator. This was used instead of calling synchronize_rcu() for each per_cpu buffer. Today, the iterator has been updated where it is safe to read the trace file while writing to the ring buffer is still occurring. There is no more need to do this synchronization and it is causing large delays on machines with many CPUs. Remove this unneeded synchronization. - Make static string array a constant in show_irq_str() Making the string array into a constant has shown to decrease code text/data size. -----BEGIN PGP SIGNATURE----- iIoEABYKADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCaIkfURQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qnx4AQCNXOuKYJXDvXrkwf449agwrn0lCVyI vV0L65nyIrakpAD8COV/lw8DhlCpb/Lijlzzo5L0n9QpEElNpq5uEntNwgE= =1YIy -----END PGP SIGNATURE----- Merge tag 'trace-ringbuffer-v6.17' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull ring-buffer updates from Steven Rostedt: - Rewind persistent ring buffer on boot When the persistent ring buffer is being used for live kernel tracing and the system crashes, the tool that is reading the trace may not have recorded the data when the system crashed.

ktest updates for v6.17
- Add new -D option that allows to override variables and options
For example:
./ktest.pl -DPATCH_START:=HEAD~1 -DOUTPUT_DIR=/work/build/urgent config
The above sets the variable "PATCH_START" to HEAD~1 and the OUTPUT_DIR
option to "/work/build/urgent".
This is useful because currently the only way to make a slight change to a
config file is by modifying that config file. For one time changes, this
can be annoying. Having a way to do a one time override from the command
line simplifies the workflow.
Temp variables (PATCH_START) will override every temp variable in the
config file, whereas options will act like a normal OVERRIDE option and
will only affect the session they define.
-DBUILD_OUTPUT=/work/git/linux.git
Replaces the default BUILD_OUTPUT option.
'-DBUILD_OUTPUT[2]=/work/git/linux.git'
Only replaces the BUILD_OUTPUT variable for test #2.
- If an option contains itself, just drop it instead of going into an
infinite loop and failing to parse (it doesn't crash, it detects the
recursion after 100 iterations anyway).
Some configs may define a variable with the same name as the option:
ADD_CONFIG := $(ADD_CONFIG)
But if the option doesn't exist, it the above will fail to parse. In these
cases, just ignore evaluating the option inside the definition of another
option if it has the same name.
- Display the BUILD_DIR and OUTPUT_DIR options at the start of every test
It is useful to know which kernel source and what destination a test is
using when it starts, in case a mistake is made. This makes it easier to
abort the test if the wrong source or destination is being used instead of
waiting until the test completes.
- Add new PATCHCHECK_SKIP option
When testing a series of commits that also includes changes to the Linux
tools directory, it is useless to test the changes in tools as they may
not affect the kernel itself. Doing tests on the kernel for changes that
do not affect the kernel is a waste of time.
Add a PATCHCHECK_SKIP that takes a series of shas that will be skipped
while doing the individual commit tests.

- Allocate string buffers from the heap for uprobe, eprobe, kprobe,
and fprobe events to avoid stack overflow
- Allocate traceprobe_parse_context from the heap to prevent
potential stack overflow
- Fix a typo in the above commit
New features for eprobe and tprobe events:
- Add support for arrays in eprobes
- Support multiple tprobes on the same tracepoint
Improve efficiency:
- Register fprobe-events only when it is enabled to reduce overhead
- Register tracepoints for tprobe events only when enabled to resolve
a lock dependency
Code Cleanup:
- Add kerneldoc for traceprobe_parse_event_name() and
__get_insn_slot()
- Sort #include alphabetically in the probes code
- Remove the unused 'mod' field from the tprobe-event
- Clean up the entry-arg storing code in probe-events
Selftest update
- Enable fprobe events before checking enable_functions in selftests"

Networking changes for 6.17.
Core & protocols
----------------
- Wrap datapath globals into net_aligned_data, to avoid false sharing.
- Preserve MSG_ZEROCOPY in forwarding (e.g. out of a container).
- Add SO_INQ and SCM_INQ support to AF_UNIX.
- Add SIOCINQ support to AF_VSOCK.
- Add TCP_MAXSEG sockopt to MPTCP.
- Add IPv6 force_forwarding sysctl to enable forwarding per interface.
- Make TCP validation of whether packet fully fits in the receive
window and the rcv_buf more strict. With increased use of HW
aggregation a single "packet" can be multiple 100s of kB.
- Add MSG_MORE flag to optimize large TCP transmissions via sockmap,
improves latency up to 33% for sockmap users.
- Convert TCP send queue handling from tasklet to BH workque.
- Improve BPF iteration over TCP sockets to see each socket exactly once.
- Remove obsolete and unused TCP RFC3517/RFC6675 loss recovery code.
- Support enabling kernel threads for NAPI processing on per-NAPI
instance basis rather than a whole device. Fully stop the kernel NAPI
thread when threaded NAPI gets disabled. Previously thread would stick
around until ifdown due to tricky synchronization.
- Allow multicast routing to take effect on locally-generated packets.
- Add output interface argument for End.X in segment routing.
- MCTP: add support for gateway routing, improve bind() handling.
- Don't require rtnl_lock when fetching an IPv6 neighbor over Netlink.
- Add a new neighbor flag ("extern_valid"), which cedes refresh
responsibilities to userspace. This is needed for EVPN multi-homing
where a neighbor entry for a multi-homed host needs to be synced
across all the VTEPs among which the host is multi-homed.
- Support NUD_PERMANENT for proxy neighbor entries.
- Add a new queuing discipline for IETF RFC9332 DualQ Coupled AQM.
- Add sequence numbers to netconsole messages. Unregister netconsole's
console when all net targets are removed. Code refactoring.
Add a number of selftests.
- Align IPSec inbound SA lookup to RFC 4301. Only SPI and protocol
should be used for an inbound SA lookup.
- Support inspecting ref_tracker state via DebugFS.
- Don't force bonding advertisement frames tx to ~333 ms boundaries.
Add broadcast_neighbor option to send ARP/ND on all bonded links.
- Allow providing upcall pid for the 'execute' command in openvswitch.
- Remove DCCP support from Netfilter's conntrack.
- Disallow multiple packet duplications in the queuing layer.
- Prevent use of deprecated iptables code on PREEMPT_RT.
Driver API
----------
- Support RSS and hashing configuration over ethtool Netlink.
- Add dedicated ethtool callbacks for getting and setting hashing fields.
- Add support for power budget evaluation strategy in PSE /
Power-over-Ethernet. Generate Netlink events for overcurrent etc.
- Support DPLL phase offset monitoring across all device inputs.
Support providing clock reference and SYNC over separate DPLL
inputs.
- Support traffic classes in devlink rate API for bandwidth management.
- Remove rtnl_lock dependency from UDP tunnel port configuration.
Device drivers
--------------
- Add a new Broadcom driver for 800G Ethernet (bnge).

Summary
* Move sysctls out of the kern_table array
This is the final move of ctl_tables into their respective subsystems. Only 5
(out of the original 50) will remain in kernel/sysctl.c file; these handle
either sysctl or common arch variables.
By decentralizing sysctl registrations, subsystem maintainers regain control
over their sysctl interfaces, improving maintainability and reducing the
likelihood of merge conflicts.
* docs: Remove false positives from check-sysctl-docs
Stopped falsely identifying sysctls as undocumented or unimplemented in the
check-sysctl-docs script. This script can now be used to automatically
identify if documentation is missing.
* Testing
All these have been in linux-next since rc3, giving them a solid 3 to 4 weeks
worth of testing. Additionally, sysctl selftests and kunit were also run
locally on my x86_64

Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 updates from Catalin Marinas:
"A quick summary: perf support for Branch Record Buffer Extensions
(BRBE), typical PMU hardware updates, small additions to MTE for
store-only tag checking and exposing non-address bits to signal
handlers, HAVE_LIVEPATCH enabled on arm64, VMAP_STACK forced on.
There is also a TLBI optimisation on hardware that does not require
break-before-make when changing the user PTEs between contiguous and
non-contiguous.

Scheduler updates for v6.17:
Core scheduler changes:
- Better tracking of maximum lag of tasks in presence of different
slices duration, for better handling of lag in the fair
scheduler. (Vincent Guittot)
- Clean up and standardize #if/#else/#endif markers throughout
the entire scheduler code base (Ingo Molnar)
- Make SMP unconditional: build the SMP scheduler's
data structures and logic on UP kernel too, even though
they are not used, to simplify the scheduler and remove
around 200 #ifdef/[#else]/#endif blocks from the
scheduler. (Ingo Molnar)
- Reorganize cgroup bandwidth control interface handling
for better interfacing with sched_ext (Tejun Heo)
Balancing:
- Bump sd->max_newidle_lb_cost when newidle balance fails (Chris Mason)
- Remove sched_domain_topology_level::flags to simplify the code (Prateek Nayak)
- Simplify and clean up build_sched_topology() (Li Chen)
- Optimize build_sched_topology() on large machines (Li Chen)
Real-time scheduling:
- Add initial version of proxy execution: a mechanism for mutex-owning
tasks to inherit the scheduling context of higher priority waiters.
Currently limited to a single runqueue and conditional on CONFIG_EXPERT,
and other limitations. (John Stultz, Peter Zijlstra, Valentin Schneider)
- Deadline scheduler (Juri Lelli):
- Fix dl_servers initialization order (Juri Lelli)
- Fix DL scheduler's root domain reinitialization logic (Juri Lelli)
- Fix accounting bugs after global limits change (Juri Lelli)
- Fix scalability regression by implementing less agressive dl_server handling
(Peter Zijlstra)
PSI:
- Improve scalability by optimizing psi_group_change() cpu_clock() usage
(Peter Zijlstra)
Rust changes:
- Make Task, CondVar and PollCondVar methods inline to avoid unnecessary
function calls (Kunwu Chan, Panagiotis Foliadis)
- Add might_sleep() support for Rust code: Rust's "#[track_caller]"
mechanism is used so that Rust's might_sleep() doesn't need to be
defined as a macro (Fujita Tomonori)
- Introduce file_from_location() (Boqun Feng)
Debugging & instrumentation:
- Make clangd usable with scheduler source code files again (Peter Zijlstra)
- tools: Add root_domains_dump.py which dumps root domains info (Juri Lelli)
- tools: Add dl_bw_dump.py for printing bandwidth accounting info (Juri Lelli)
Misc cleanups & fixes:
- Remove play_idle() (Feng Lee)
- Fix check_preemption_disabled() (Sebastian Andrzej Siewior)
- Do not call __put_task_struct() on RT if pi_blocked_on is set
(Luis Claudio R. Goncalves)
- Correct the comment in place_entity() (wang wei)

defined as a macro (Fujita Tomonori)
- Introduce file_from_location() (Boqun Feng)
Debugging & instrumentation:
- Make clangd usable with scheduler source code files again (Peter
Zijlstra)
- tools: Add root_domains_dump.py which dumps root domains info (Juri
Lelli)
- tools: Add dl_bw_dump.py for printing bandwidth accounting info
(Juri Lelli)
Misc cleanups & fixes:
- Remove play_idle() (Feng Lee)
- Fix check_preemption_disabled() (Sebastian Andrzej Siewior)
- Do not call __put_task_struct() on RT if pi_blocked_on is set (Luis
Claudio R. Goncalves)
- Correct the comment in place_entity() (wang wei)"

compiler_types: Provide __no_kstack_erase to disable coverage only on Clang
In order to support Clang's stack depth tracking (for Linux's kstack_erase
feature), the coverage sanitizer needed to be disabled for __init (and
__head) section code. Doing this universally (i.e. for GCC too) created
a number of unexpected problems, ranging from changes to inlining logic
to failures to DCE code on earlier GCC versions.
Since this change is only needed for Clang, specialize it so that GCC
doesn't see the change as it isn't needed there (the GCC implementation
of kstack_erase uses a GCC plugin that removes stack depth tracking
instrumentation from __init sections during a late pass in the IR).
Successfully build and boot tested with GCC 12 and Clang 22.

fortify: Fix incorrect reporting of read buffer size
When FORTIFY_SOURCE reports about a run-time buffer overread, the wrong
buffer size was being shown in the error message. (The bounds checking
was correct.)

kstack_erase: Fix missed export of renamed KSTACK_ERASE_CFLAGS
Certain targets disable kstack_erase by filtering out KSTACK_ERASE_CFLAGS
rather than adding DISABLE_KSTACK_ERASE. The renaming to kstack_erase
missed the CFLAGS export, which broke those build targets (e.g. x86
vdso32).
