e3a22b5320 Documentation: Coccinelle: document debug log handling
The current debug documentation does not mention that logs are printed
to stdout unless DEBUG_FILE is set. It also doesn't mention that
Coccinelle cannot overwrite debug files.

Document this behaviour in the examples and reference it in the
debugging section.

0201eedb69 ipv6: icmp: remove obsolete code in icmpv6_xrlim_allow()
Following part was needed before the blamed commit, because
inet_getpeer_v6() second argument was the prefix.

	/* Give more bandwidth to wider prefixes. */
	if (rt->rt6i_dst.plen < 128)
		tmo >>= ((128 - rt->rt6i_dst.plen)>>5);

Now inet_getpeer_v6() retrieves hosts, we need to remove
@tmo adjustement or wider prefixes likes /24 allow 8x
more ICMP to be sent for a given ratelimit.

As we had this issue for a while, this patch changes net.ipv6.icmp.ratelimit
default value from 1000ms to 100ms to avoid potential regressions.

Also add a READ_ONCE() when reading net->ipv6.sysctl.icmpv6_time.

Pull more power management updates from Rafael Wysocki:
 "These are mostly fixes on top of the power management updates merged
  recently in cpuidle governors, in the Intel RAPL power capping driver
  and in the wake IRQ management code:

   - Fix the handling of package-scope MSRs in the intel_rapl power
     capping driver when called from the PMU subsystem and make it add
     all package CPUs to the PMU cpumask to allow tools to read RAPL
     events from any CPU in the package (Kuppuswamy Satharayananyan)

   - Rework the invalid version check in the intel_rapl_tpmi power
     capping driver to account for the fact that on partitioned systems,
     multiple TPMI instances may exist per package, but RAPL registers
     are only valid on one instance (Kuppuswamy Satharayananyan)

   - Describe the new intel_idle.table command line option in the
     admin-guide intel_idle documentation (Artem Bityutskiy)

   - Fix a crash in the ladder cpuidle governor on systems with only one
     (polling) idle state available by making the cpuidle core bypass
     the governor in those cases and adjust the other existing governors
     to that change (Aboorva Devarajan, Christian Loehle)

   - Update kerneldoc comments for wake IRQ management functions that
     have not been matching the code (Wang Jiayue)"

80ca113671 ASoC: dt-bindings: asahi-kasei,ak5558: Fix the supply names
In the original txt format binding document ak4458.txt, the supply names
are 'AVDD-supply', 'DVDD-supply', and they are also used in driver. But in
the commit converting to yaml format, they are changed to 'avdd-supply',
'dvdd-supply'. After search all the dts file, these names 'AVDD-supply',
'DVDD-supply', 'avdd-supply', 'dvdd-supply' are not used in any dts
file. So it is safe to fix the yaml binding document.

a07c33c6f2 vsock: document namespace mode sysctls
Add documentation for the vsock per-namespace sysctls (`ns_mode` and
`child_ns_mode`) to Documentation/admin-guide/sysctl/net.rst.
These sysctls were introduced by commit eafb64f40c ("vsock: add
netns to vsock core").

Document the two namespace modes (`global` and `local`), the
inheritance behavior of `child_ns_mode`, and the restriction preventing
local namespaces from setting `child_ns_mode` to `global`.

Pull more misc vfs updates from Christian Brauner:
 "Features:

   - Optimize close_range() from O(range size) to O(active FDs) by using
     find_next_bit() on the open_fds bitmap instead of linearly scanning
     the entire requested range. This is a significant improvement for
     large-range close operations on sparse file descriptor tables.

   - Add FS_XFLAG_VERITY file attribute for fs-verity files, retrievable
     via FS_IOC_FSGETXATTR and file_getattr(). The flag is read-only.
     Add tracepoints for fs-verity enable and verify operations,
     replacing the previously removed debug printk's.

   - Prevent nfsd from exporting special kernel filesystems like pidfs
     and nsfs. These filesystems have custom ->open() and ->permission()
     export methods that are designed for open_by_handle_at(2) only and
     are incompatible with nfsd. Update the exportfs documentation
     accordingly.

  Fixes:

   - Fix KMSAN uninit-value in ovl_fill_real() where strcmp() was used
     on a non-null-terminated decrypted directory entry name from
     fscrypt. This triggered on encrypted lower layers when the
     decrypted name buffer contained uninitialized tail data.

     The fix also adds VFS-level name_is_dot(), name_is_dotdot(), and
     name_is_dot_dotdot() helpers, replacing various open-coded "." and
     ".." checks across the tree.

   - Fix read-only fsflags not being reset together with xflags in
     vfs_fileattr_set(). Currently harmless since no read-only xflags
     overlap with flags, but this would cause inconsistencies for any
     future shared read-only flag

   - Return -EREMOTE instead of -ESRCH from PIDFD_GET_INFO when the
     target process is in a different pid namespace. This lets userspace
     distinguish "process exited" from "process in another namespace",
     matching glibc's pidfd_getpid() behavior

  Cleanups:

   - Use C-string literals in the Rust seq_file bindings, replacing the
     kernel::c_str!() macro (available since Rust 1.77)

   - Fix typo in d_walk_ret enum comment, add porting notes for the
     readlink_copy() calling convention change"

Pull clk updates from Stephen Boyd:
 "Not much changed in the clk framework this time except the clk.h
  consumer API moved the context saving APIs around to fix a build error
  in certain configurations.

  There was a change to the core framework for CLK_OPS_PARENT_ENABLE
  behavior during registration, but it wrecked existing drivers that
  didn't expect things to be turned off during clk registration so it
  got reverted.

  This cycle is really a large collection of new clk drivers, primarily
  for Qualcomm SoCs but also for Amlogic, SpacemiT, Google, and Aspeed.
  Another big change in here is support for automatic hardware clock
  gating on Samsung SoCs where the clks turn on and off when needed.
  Ideally more vendors move to this method for better power savings. The
  highlights are in the updates section below.

  Beyond all the new drivers we have a bunch of cleanups like converting
  drivers from divider_round_rate() to divider_determine_rate() and
  using scoped for each OF child loops. Otherwise it's the usual data
  fixes and plugging reference leaks, etc. that's all pretty ordinary
  but not critical enough to fix until the next release.

  New Drivers:
   - Qualcomm Kaanapali global, tcsr, rpmh, display, gpu, camera, and
     video clk controllers
   - Qualcomm SM8750 camera clk controllers
   - Qualcomm MSM8940 and SDM439 global clk controllers
   - Google GS101 Display Process Unit (DPU) clk controllers
   - SpacemiT K3 clk controllers
   - Amlogic t7 clk controllers
   - Aspeed AST2700 clk controllers

  Updates:
   - Convert clock dividers from round_rate() to determine_rate()
   - Fix sparse warnings, kernel-doc warnings, and plug leaked OF refs
   - Automatic hardware clk gating on Google GS101 SoCs
   - Amlogic s4 video clks
   - CAN-FD clks and resets on Renesas RZ/T2H, RZ/N2H, RZ/V2H, and
     RZ/V2N
   - Expanded Serial Peripheral Interface (xSPI) clocks and resets on
     Renesas RZ/T21H and RZ/N2H
   - DMAC, interrupt controller (ICU), SPI, and thermal (TSU) clocks and
     resets on Renesas RZ/V2N
   - More serial (RSCI) clocks and resets on Renesas RZ/V2H and RZ/V2N
   - CPU frequency scaling on T-HEAD TH1520"

Pull f2fs updates from Jaegeuk Kim:
 "In this development cycle, we focused on several key performance
  optimizations:

   - introducing large folio support to enhance read speeds for
     immutable files

   - reducing checkpoint=enable latency by flushing only committed dirty
     pages

   - implementing tracepoints to diagnose and resolve lock priority
     inversion.

  Additionally, we introduced the packed_ssa feature to optimize the SSA
  footprint when utilizing large block sizes.

  Detail summary:

  Enhancements:
   - support large folio for immutable non-compressed case
   - support non-4KB block size without packed_ssa feature
   - optimize f2fs_enable_checkpoint() to avoid long delay
   - optimize f2fs_overwrite_io() for f2fs_iomap_begin
   - optimize NAT block loading during checkpoint write
   - add write latency stats for NAT and SIT blocks in

Pull tracing updates from Steven Rostedt:
 "User visible changes:

   - Add an entry into MAINTAINERS file for RUST versions of code

     There's now RUST code for tracing and static branches. To
     differentiate that code from the C code, add entries in for the
     RUST version (with "[RUST]" around it) so that the right
     maintainers get notified on changes.

   - New bitmask-list option added to tracefs

     When this is set, bitmasks in trace event are not displayed as hex
     numbers, but instead as lists: e.g. 0-5,7,9 instead of 0000015f

   - New show_event_filters file in tracefs

     Instead of having to search all events/*/*/filter for any active
     filters enabled in the trace instance, the file show_event_filters
     will list them so that there's only one file that needs to be
     examined to see if any filters are active.

   - New show_event_triggers file in tracefs

     Instead of having to search all events/*/*/trigger for any active
     triggers enabled in the trace instance, the file
     show_event_triggers will list them so that there's only one file
     that needs to be examined to see if any triggers are active.

   - Have traceoff_on_warning disable trace pintk buffer too

     Recently recording of trace_printk() could go to other trace
     instances instead of the top level instance. But if
     traceoff_on_warning triggers, it doesn't stop the buffer with
     trace_printk() and that data can easily be lost by being
     overwritten. Have traceoff_on_warning also disable the instance
     that has trace_printk() being written to it.

   - Update the hist_debug file to show what function the field uses

     When CONFIG_HIST_TRIGGERS_DEBUG is enabled, a hist_debug file
     exists for every event. This displays the internal data of any
     histogram enabled for that event. But it is lacking the function
     that is called to process one of its fields. This is very useful
     information that was missing when debugging histograms.

   - Up the histogram stack size from 16 to 31

     Stack traces can be used as keys for event histograms. Currently
     the size of the stack that is stored is limited to just 16 entries.
     But the storage space in the histogram is 256 bytes, meaning that
     it can store up to 31 entries (plus one for the count of entries).
     Instead of letting that space go to waste, up the limit from 16 to
     31. This makes the keys much more useful.

   - Fix permissions of per CPU file buffer_size_kb

     The per CPU file of buffer_size_kb was incorrectly set to read only
     in a previous cleanup. It should be writable.

   - Reset "last_boot_info" if the persistent buffer is cleared

     The last_boot_info shows address information of a persistent ring
     buffer if it contains data from a previous boot. It is cleared when
     recording starts again, but it is not cleared when the buffer is
     reset. The data is useless after a reset so clear it on reset too.

  Internal changes:

   - A change was made to allow tracepoint callbacks to have preemption
     enabled, and instead be protected by SRCU. This required some
     updates to the callbacks for perf and BPF.

     perf needed to disable preemption directly in its callback because
     it expects preemption disabled in the later code.

     BPF needed to disable migration, as its code expects to run
     completely on the same CPU.

   - Have irq_work wake up other CPU if current CPU is "isolated"

     When there's a waiter waiting on ring buffer data and a new event
     happens, an irq work is triggered to wake up that waiter. This is
     noisy on isolated CPUs (running NO_HZ_FULL). Trigger an IPI to a
     house keeping CPU instead.

   - Use proper free of trigger_data instead of open coding it in.

   - Remove redundant call of event_trigger_reset_filter()

     It was called immediately in a function that was called right after
     it.

   - Workqueue cleanups

   - Report errors if tracing_update_buffers() were to fail.

   - Make the enum update workqueue generic for other parts of tracing

     On boot up, a work queue is created to convert enum names into
     their numbers in the trace event format files. This work queue can
     also be used for other aspects of tracing that takes some time and
     shouldn't be called by the init call code.

     The blk_trace initialization takes a bit of time. Have the
     initialization code moved to the new tracing generic work queue
     function.

   - Skip kprobe boot event creation call if there's no kprobes defined
     on cmdline

     The kprobe initialization to set up kprobes if they are defined on
     the cmdline requires taking the event_mutex lock. This can be held
     by other tracing code doing initialization for a long time. Since
     kprobes added to the kernel command line need to be setup
     immediately, as they may be tracing early initialization code, they
     cannot be postponed in a work queue and must be setup in the
     initcall code.

     If there's no kprobe on the kernel cmdline, there's no reason to
     take the mutex and slow down the boot up code waiting to get the
     lock only to find out there's nothing to do. Simply exit out early
     if there's no kprobes on the kernel cmdline.

     If there are kprobes on the cmdline, then someone cares more about
     tracing over the speed of boot up.

   - Clean up the trigger code a bit

   - Move code out of trace.c and into their own files

     trace.c is now over 11,000 lines of code and has become more
     difficult to maintain. Start splitting it up so that related code
     is in their own files.

     Move all the trace_printk() related code into trace_printk.c.

     Move the __always_inline stack functions into trace.h.

     Move the pid filtering code into a new trace_pid.c file.

   - Better define the max latency and snapshot code

     The latency tracers have a "max latency" buffer that is a copy of
     the main buffer and gets swapped with it when a new high latency is
     detected. This keeps the trace up to the highest latency around
     where this max_latency buffer is never written to. It is only used
     to save the last max latency trace.

     A while ago a snapshot feature was added to tracefs to allow user
     space to perform the same logic. It could also enable events to
     trigger a "snapshot" if one of their fields hit a new high. This
     was built on top of the latency max_latency buffer logic.

     Because snapshots came later, they were dependent on the latency
     tracers to be enabled. In reality, the latency tracers depend on
     the snapshot code and not the other way around. It was just that
     they came first.

     Restructure the code and the kconfigs to have the latency tracers
     depend on snapshot code instead. This actually simplifies the logic
     a bit and allows to disable more when the latency tracers are not
     defined and the snapshot code is.

   - Fix a "false sharing" in the hwlat tracer code

     The loop to search for latency in hardware was using a variable
     that could be changed by user space for each sample. If the user
     change this variable, it could cause a bus contention, and reading
     that variable can show up as a large latency in the trace causing a
     false positive. Read this variable at the start of the sample with
     a READ_ONCE() into a local variable and keep the code from sharing
     cache lines with readers.

   - Fix function graph tracer static branch optimization code

     When only one tracer is defined for function graph tracing, it uses
     a static branch to call that tracer directly. When another tracer
     is added, it goes into loop logic to call all the registered
     callbacks.

     The code was incorrect when going back to one tracer and never
     re-enabled the static branch again to do the optimization code.

   - And other small fixes and cleanups"

   - Fix return value for memory reads from and writes to in-kernel

   - Add sanitisation of the VTCR_EL2 register, fixing a number of

   - Make sure that MTE being disabled on the pKVM host doesn't give it
     the ability to attack the hypervisor

   - Allow pKVM's host stage-2 mappings to use the Force Write Back
     version of the memory attributes by using the "pass-through'

   - Fix trapping of ICC_DIR_EL1 on GICv5 hosts emulating GICv3 for the

   - Preliminary work for guest GICv5 support

   - A bunch of debugfs fixes, removing pointless custom iterators
     stored in guest data structures

   - A small set of FPSIMD cleanups

   - Selftest fixes addressing the incorrect alignment of page
     allocation

   - Other assorted low-impact fixes and spelling fixes

  RISC-V:

   - Fixes for issues discoverd by KVM API fuzzing in
     kvm_riscv_aia_imsic_has_attr(), kvm_riscv_aia_imsic_rw_attr(), and
     kvm_riscv_vcpu_aia_imsic_update()

   - Allow Zalasr, Zilsd and Zclsd extensions for Guest/VM

   - Transparent huge page support for hypervisor page tables

   - Adjust the number of available guest irq files based on MMIO
     register sizes found in the device tree or the ACPI tables

   - Add RISC-V specific paging modes to KVM selftests

   - Detect paging mode at runtime for selftests

  s390:

   - Performance improvement for vSIE (aka nested virtualization)

   - Completely new memory management. s390 was a special snowflake that
     enlisted help from the architecture's page table management to
     build hypervisor page tables, in particular enabling sharing the
     last level of page tables. This however was a lot of code (~3K
     lines) in order to support KVM, and also blocked several features.
     The biggest advantages is that the page size of userspace is
     completely independent of the page size used by the guest:
     userspace can mix normal pages, THPs and hugetlbfs as it sees fit,
     and in fact transparent hugepages were not possible before. It's
     also now possible to have nested guests and guests with huge pages
     running on the same host

   - Maintainership change for s390 vfio-pci

   - Small quality of life improvement for protected guests

  x86:

   - Add support for giving the guest full ownership of PMU hardware
     (contexted switched around the fastpath run loop) and allowing
     direct access to data MSRs and PMCs (restricted by the vPMU model).

     KVM still intercepts access to control registers, e.g. to enforce
     event filtering and to prevent the guest from profiling sensitive
     host state. This is more accurate, since it has no risk of
     contention and thus dropped events, and also has significantly less
     overhead.

     For more information, see the commit message for merge commit
     bf2c3138ae ("Merge tag 'kvm-x86-pmu-6.20' ...")

   - Disallow changing the virtual CPU model if L2 is active, for all
     the same reasons KVM disallows change the model after the first
     KVM_RUN

   - Fix a bug where KVM would incorrectly reject host accesses to PV
     MSRs when running with KVM_CAP_ENFORCE_PV_FEATURE_CPUID enabled,
     even if those were advertised as supported to userspace,

   - Fix a bug with protected guest state (SEV-ES/SNP and TDX) VMs,

     (for x86 only) to enforce usage of EXPORT_SYMBOL_FOR_KVM_INTERNAL.
     Only a few exports that are intended for external usage, and those
     are allowed explicitly

   - When checking nested events after a vCPU is unblocked, ignore
     -EBUSY instead of WARNing. Userspace can sometimes put the vCPU
     into what should be an impossible state, and spurious exit to
     userspace on -EBUSY does not really do anything to solve the issue

   - Also throw in the towel and drop the WARN on INIT/SIPI being
     blocked when vCPU is in Wait-For-SIPI, which also resulted in
     playing whack-a-mole with syzkaller stuffing architecturally
     impossible states into KVM

   - Add support for new Intel instructions that don't require anything
     beyond enumerating feature flags to userspace

   - Grab SRCU when reading PDPTRs in KVM_GET_SREGS2

   - Add WARNs to guard against modifying KVM's CPU caps outside of the
     intended setup flow, as nested VMX in particular is sensitive to
     unexpected changes in KVM's golden configuration

   - Add a quirk to allow userspace to opt-in to actually suppress EOI
     broadcasts when the suppression feature is enabled by the guest
     (currently limited to split IRQCHIP, i.e. userspace I/O APIC).
     Sadly, simply fixing KVM to honor Suppress EOI Broadcasts isn't an
     option as some userspaces have come to rely on KVM's buggy behavior
     (KVM advertises Supress EOI Broadcast irrespective of whether or
     not userspace I/O APIC supports Directed EOIs)

   - Clean up KVM's handling of marking mapped vCPU pages dirty

   - Drop a pile of *ancient* sanity checks hidden behind in KVM's
     unused ASSERT() macro, most of which could be trivially triggered
     by the guest and/or user, and all of which were useless

   - Fold "struct dest_map" into its sole user, "struct rtc_status", to
     make it more obvious what the weird parameter is used for, and to
     allow fropping these RTC shenanigans if CONFIG_KVM_IOAPIC=n

   - Bury all of ioapic.h, i8254.h and related ioctls (including
     KVM_CREATE_IRQCHIP) behind CONFIG_KVM_IOAPIC=y

   - Add a regression test for recent APICv update fixes

   - Handle "hardware APIC ISR", a.k.a. SVI, updates in
     kvm_apic_update_apicv() to consolidate the updates, and to
     co-locate SVI updates with the updates for KVM's own cache of ISR
     information

   - Drop a dead function declaration

   - Minor cleanups

  x86 (Intel):

   - Rework KVM's handling of VMCS updates while L2 is active to
     temporarily switch to vmcs01 instead of deferring the update until
     the next nested VM-Exit.

     The deferred updates approach directly contributed to several bugs,
     was proving to be a maintenance burden due to the difficulty in
     auditing the correctness of deferred updates, and was polluting
     "struct nested_vmx" with a growing pile of booleans

   - Fix an SGX bug where KVM would incorrectly try to handle EPCM page
     faults, and instead always reflect them into the guest. Since KVM
     doesn't shadow EPCM entries, EPCM violations cannot be due to KVM
     interference and can't be resolved by KVM

   - Fix a bug where KVM would register its posted interrupt wakeup
     handler even if loading kvm-intel.ko ultimately failed

   - Disallow access to vmcb12 fields that aren't fully supported,
     mostly to avoid weirdness and complexity for FRED and other
     features, where KVM wants enable VMCS shadowing for fields that
     conditionally exist

   - Print out the "bad" offsets and values if kvm-intel.ko refuses to
     load (or refuses to online a CPU) due to a VMCS config mismatch

  x86 (AMD):

   - Drop a user-triggerable WARN on nested_svm_load_cr3() failure

   - Add support for virtualizing ERAPS. Note, correct virtualization of
     ERAPS relies on an upcoming, publicly announced change in the APM
     to reduce the set of conditions where hardware (i.e. KVM) *must*
     flush the RAP

   - Ignore nSVM intercepts for instructions that are not supported
     according to L1's virtual CPU model

   - Add support for expedited writes to the fast MMIO bus, a la VMX's
     fastpath for EPT Misconfig

   - Don't set GIF when clearing EFER.SVME, as GIF exists independently
     of SVM, and allow userspace to restore nested state with GIF=0

   - Treat exit_code as an unsigned 64-bit value through all of KVM

   - Add support for fetching SNP certificates from userspace

   - Fix a bug where KVM would use vmcb02 instead of vmcb01 when
     emulating VMLOAD or VMSAVE on behalf of L2

   - Misc fixes and cleanups

  x86 selftests:

   - Add a regression test for TPR<=>CR8 synchronization and IRQ masking

   - Overhaul selftest's MMU infrastructure to genericize stage-2 MMU
     support, and extend x86's infrastructure to support EPT and NPT
     (for L2 guests)

   - Extend several nested VMX tests to also cover nested SVM

   - Add a selftest for nested VMLOAD/VMSAVE

   - Rework the nested dirty log test, originally added as a regression
     test for PML where KVM logged L2 GPAs instead of L1 GPAs, to
     improve test coverage and to hopefully make the test easier to
     understand and maintain

  guest_memfd:

   - Remove kvm_gmem_populate()'s preparation tracking and half-baked
     hugepage handling. SEV/SNP was the only user of the tracking and it
     can do it via the RMP

   - Retroactively document and enforce (for SNP) that
     KVM_SEV_SNP_LAUNCH_UPDATE and KVM_TDX_INIT_MEM_REGION require the
     source page to be 4KiB aligned, to avoid non-trivial complexity for
     something that no known VMM seems to be doing and to avoid an API
     special case for in-place conversion, which simply can't support
     unaligned sources

   - When populating guest_memfd memory, GUP the source page in common
     code and pass the refcounted page to the vendor callback, instead
     of letting vendor code do the heavy lifting. Doing so avoids a
     looming deadlock bug with in-place due an AB-BA conflict betwee
     mmap_lock and guest_memfd's filemap invalidate lock

  Generic:

   - Fix a bug where KVM would ignore the vCPU's selected address space
     when creating a vCPU-specific mapping of guest memory. Actually
     this bug could not be hit even on x86, the only architecture with
     multiple address spaces, but it's a bug nevertheless"
