When CONFIG_FB_DEVICE is disabled, struct fb_info does

which is a conditional scheduling point based on printk's internal
variables console_may_schedule. It may only be used if the console lock
is acquired for instance via console_lock() or console_trylock().
Prinkt sets the internal variable to 1 (and allows to schedule)
if the console lock has been acquired via console_lock(). The trylock
does not allow it.
The console_conditional_schedule() invocation in do_con_write() is
invoked shortly before console_unlock().
The console_conditional_schedule() invocation in fbcon_redraw.*()
original from fbcon_scroll() / vt's con_scroll() which originate from a
line feed.
In console_unlock() the variable is set to 0 (forbids to schedule) and
it tries to schedule while making progress printing. This is brand new
compared to when console_conditional_schedule() was added in v2.4.9.11.
In v2.6.38-rc3, console_unlock() (started its existence) iterated over
all consoles and flushed them with disabled interrupts. A scheduling
attempt here was not possible, it relied that a long print scheduled
before console_unlock().
Since commit 8d91f8b15361d ("printk: do cond_resched() between lines
while outputting to consoles"), which appeared in v4.5-rc1,
console_unlock() attempts to schedule if it was allowed to schedule
while during console_lock(). Each record is idealy one line so after
every line feed.
This console_conditional_schedule() is also only relevant on
PREEMPT_NONE and PREEMPT_VOLUNTARY builds. In other configurations
cond_resched() becomes a nop and has no impact.
I'm bringing this all up just proof that it is not required anymore. It
becomes a problem on a PREEMPT_RT build with debug code enabled because
that might_sleep() in cond_resched() remains and triggers a warnings.
This is due to
and vt_console_print() acquires a spinlock_t which does not allow a
voluntary schedule. There is no need to fb_scroll() to schedule since
console_flush_one_record() attempts to schedule after each line.
!PREEMPT_RT is not affected because the legacy printing thread is only
enabled on PREEMPT_RT builds.
Therefore I suggest to remove console_conditional_schedule().

A userspace program can trigger the RIVA NV3 arbitration code by calling

first.
In a normal setup, state->mclk_khz is provided by the real hardware and is
non-zero. However, an attacker can construct a malicious or misconfigured
device (e.g. a crafted/emulated PCI device) that exposes a bogus PLL
configuration, causing state->mclk_khz to become zero. Once
nv3_get_param() calls nv3_arb(), the division by state->mclk_khz in the gns

"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.

- Add more CPUCFG mask bits
- Improve feature detection
- Add lazy load support for FPU and binary translation (LBT) register
state
- Fix return value for memory reads from and writes to in-kernel
devices
- Add support for detecting preemption from within a guest
- Add KVM steal time test case to tools/selftests
ARM:
- Add support for FEAT_IDST, allowing ID registers that are not
implemented to be reported as a normal trap rather than as an UNDEF
exception
- Add sanitisation of the VTCR_EL2 register, fixing a number of
UXN/PXN/XN bugs in the process
- Full handling of RESx bits, instead of only RES0, and resulting in
SCTLR_EL2 being added to the list of sanitised registers
- More pKVM fixes for features that are not supposed to be exposed to
guests
- 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'
encoding
- Fix trapping of ICC_DIR_EL1 on GICv5 hosts emulating GICv3 for the
guest
- 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 bf2c3138ae36 ("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,
where KVM would attempt to read CR3 configuring an async #PF entry
- Fail the build if EXPORT_SYMBOL_GPL or EXPORT_SYMBOL is used in KVM
(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"

we try to re-enable direct mode via ftrace_graph_enable_direct(true, ...).
But ftrace_graph_enable_direct() incorrectly disables the static key

mm/hugetlb: restore failed global reservations to subpool
Commit a833a693a490 ("mm: hugetlb: fix incorrect fallback for subpool")
fixed an underflow error for hstate->resv_huge_pages caused by incorrectly
attributing globally requested pages to the subpool's reservation.
Unfortunately, this fix also introduced the opposite problem, which would
leave spool->used_hpages elevated if the globally requested pages could
not be acquired. This is because while a subpool's reserve pages only
accounts for what is requested and allocated from the subpool, its "used"
counter keeps track of what is consumed in total, both from the subpool
and globally. Thus, we need to adjust spool->used_hpages in the other
direction, and make sure that globally requested pages are uncharged from
the subpool's used counter.
Each failed allocation attempt increments the used_hpages counter by how
many pages were requested from the global pool. Ultimately, this renders
the subpool unusable, as used_hpages approaches the max limit.
The issue can be reproduced as follows:
1. Allocate 4 hugetlb pages
2. Create a hugetlb mount with max=4, min=2
3. Consume 2 pages globally
4. Request 3 pages from the subpool (2 from subpool + 1 from global)
4.1 hugepage_subpool_get_pages(spool, 3) succeeds.
used_hpages += 3
4.2 hugetlb_acct_memory(h, 1) fails: no global pages left
used_hpages -= 2
5. Subpool now has used_hpages = 1, despite not being able to
successfully allocate any hugepages. It believes it can now only
allocate 3 more hugepages, not 4.
With each failed allocation attempt incrementing the used counter, the
subpool eventually reaches a point where its used counter equals its
max counter. At that point, any future allocations that try to
allocate hugeTLB pages from the subpool will fail, despite the subpool
not having any of its hugeTLB pages consumed by any user.
Once this happens, there is no way to make the subpool usable again,
since there is no way to decrement the used counter as no process is
really consuming the hugeTLB pages.
The underflow issue that the original commit fixes still remains fixed
as well.
Without this fix, used_hpages would keep on leaking if
hugetlb_acct_memory() fails.

- Set stop threshold after enabling instances
Prefer recording samples without stopping on them on the start of
tracing to stopping on samples that are never recorded. This fixes

them into a new function to reduce code duplication.

individually. Now that we have a common structure for parameters,
unify the parsing of those options common among all four tools into
one function.

- Refactor da_monitor to minimize macros
Complete refactor of da_monitor.h to reduce reliance on macros
generating functions. Use generic static functions and uses the
preprocessor only when strictly necessary (e.g. for tracepoint
handlers).
The change essentially relies on functions with generic names (e.g.
da_handle) instead of monitor-specific as well adding the need to
define constant (e.g. MONITOR_NAME, MONITOR_TYPE) before including
the header rather than calling macros that would define functions.
Also adapt monitors and documentation accordingly.

Clean up functions in dot2c removing reimplementations of trivial
library functions (__buff_to_string) and removing some other unused
intermediate steps.
- Annotate functions with types in the rvgen python scripts
- Remove superfluous assignments and cleanup generated code
The rvgen scripts generate a superfluous assignment to 0 for enum
variables and don't add commas to the last elements, which is against
the kernel coding standards. Change the generation process for a
better compliance and slightly simpler logic.
- Remove superfluous declarations from generated code

Pull nfsd updates from Chuck Lever:
"Neil Brown and Jeff Layton contributed a dynamic thread pool sizing
mechanism for NFSD. The sunrpc layer now tracks minimum and maximum
thread counts per pool, and NFSD adjusts running thread counts based
on workload: idle threads exit after a timeout when the pool exceeds
its minimum, and new threads spawn automatically when all threads are
busy. Administrators control this behavior via the nfsdctl netlink
interface.
Rick Macklem, FreeBSD NFS maintainer, generously contributed server-
side support for the POSIX ACL extension to NFSv4, as specified in
draft-ietf-nfsv4-posix-acls. This extension allows NFSv4 clients to
get and set POSIX access and default ACLs using native NFSv4
operations, eliminating the need for sideband protocols. The feature
is gated by a Kconfig option since the IETF draft has not yet been
ratified.
Chuck Lever delivered numerous improvements to the xdrgen tool. Error
reporting now covers parsing, AST transformation, and invalid
declarations. Generated enum decoders validate incoming values against
valid enumerator lists. New features include pass-through line support
for embedding C directives in XDR specifications, 16-bit integer
types, and program number definitions. Several code generation issues
were also addressed.
When an administrator revokes NFSv4 state for a filesystem via the
unlock_fs interface, ongoing async COPY operations referencing that
filesystem are now cancelled, with CB_OFFLOAD callbacks notifying
affected clients.
The remaining patches in this pull request are clean-ups and minor
optimizations. Sincere thanks to all contributors, reviewers, testers,
and bug reporters who participated in the v7.0 NFSD development cycle"

Pull networking updates from Paolo Abeni:
"Core & protocols:
- A significant effort all around the stack to guide the compiler to
make the right choice when inlining code, to avoid unneeded calls
for small helper and stack canary overhead in the fast-path.
This generates better and faster code with very small or no text
size increases, as in many cases the call generated more code than
the actual inlined helper.
- Extend AccECN implementation so that is now functionally complete,
also allow the user-space enabling it on a per network namespace
basis.
- Add support for memory providers with large (above 4K) rx buffer.
Paired with hw-gro, larger rx buffer sizes reduce the number of
buffers traversing the stack, dincreasing single stream CPU usage
by up to ~30%.
- Do not add HBH header to Big TCP GSO packets. This simplifies the
RX path, the TX path and the NIC drivers, and is possible because
user-space taps can now interpret correctly such packets without
the HBH hint.
- Allow IPv6 routes to be configured with a gateway address that is
resolved out of a different interface than the one specified,
aligning IPv6 to IPv4 behavior.
- Multi-queue aware sch_cake. This makes it possible to scale the
rate shaper of sch_cake across multiple CPUs, while still enforcing
a single global rate on the interface.
- Add support for the nbcon (new buffer console) infrastructure to
netconsole, enabling lock-free, priority-based console operations
that are safer in crash scenarios.
- Improve the TCP ipv6 output path to cache the flow information,
saving cpu cycles, reducing cache line misses and stack use.
- Improve netfilter packet tracker to resolve clashes for most
protocols, avoiding unneeded drops on rare occasions.
- Add IP6IP6 tunneling acceleration to the flowtable infrastructure.
- Reduce tcp socket size by one cache line.
- Notify neighbour changes atomically, avoiding inconsistencies
between the notification sequence and the actual states sequence.
- Add vsock namespace support, allowing complete isolation of vsocks
across different network namespaces.
- Improve xsk generic performances with cache-alignment-oriented
optimizations.
- Support netconsole automatic target recovery, allowing netconsole
to reestablish targets when underlying low-level interface comes
back online.
Driver API:
- Support for switching the working mode (automatic vs manual) of a
DPLL device via netlink.
- Introduce PHY ports representation to expose multiple front-facing
media ports over a single MAC.
- Introduce "rx-polarity" and "tx-polarity" device tree properties,
to generalize polarity inversion requirements for differential
signaling.
- Add helper to create, prepare and enable managed clocks.
- Add ethernet driver for MaxLinear MxL862xx switches
- Remove parallel-port Ethernet driver.
- Convert existing driver timestamp configuration reporting to
hwtstamp_get and remove legacy ioctl().
- Convert existing drivers to .get_rx_ring_count(), simplifing the RX
ring count retrieval. Also remove the legacy fallback path.

tracing: Fix indentation of return statement in print_trace_fmt()
The return statement inside the nested if block in print_trace_fmt()
is not properly indented, making the code structure unclear. This was
flagged by smatch as a warning.
Add proper indentation to the return statement to match the kernel
coding style and improve readability.

Merge tag 'driver-core-7.0-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/driver-core/driver-core
Pull driver core updates from Danilo Krummrich:
"Bus:
- Ensure bus->match() is consistently called with the device lock
held
- Improve type safety of bus_find_device_by_acpi_dev()
Devtmpfs:
- Parse 'devtmpfs.mount=' boot parameter with kstrtoint() instead of
simple_strtoul()
- Avoid sparse warning by making devtmpfs_context_ops static
IOMMU:
- Do not register the qcom_smmu_tbu_driver in arm_smmu_device_probe()
MAINTAINERS:
- Add the new driver-core mailing list (driver-core@lists.linux.dev)
to all relevant entries
- Add missing tree location for "FIRMWARE LOADER (request_firmware)"
- Add driver-model documentation to the "DRIVER CORE" entry
- Add missing driver-core maintainers to the "AUXILIARY BUS" entry
Misc:
- Change return type of attribute_container_register() to void; it
has always been infallible
- Do not export sysfs_change_owner(), sysfs_file_change_owner() and
device_change_owner()
- Move devres_for_each_res() from the public devres header to
drivers/base/base.h
- Do not use a static struct device for the faux bus; allocate it
dynamically
Revocable:
- Patches for the revocable synchronization primitive have been
scheduled for v7.0-rc1, but have been reverted as they need some
more refinement
Rust:
- Device:
- Support dev_printk on all device types, not just the core Device
struct; remove now-redundant .as_ref() calls in dev_* print
calls
- Devres:
- Introduce an internal reference count in Devres<T> to avoid a
deadlock condition in case of (indirect) nesting
- DMA:
- Allow drivers to tune the maximum DMA segment size via
dma_set_max_seg_size()
- I/O:
- Introduce the concept of generic I/O backends to handle
different kinds of device shared memory through a common
interface.
This enables higher-level concepts such as register
abstractions, I/O slices, and field projections to be built
generically on top.
In a first step, introduce the Io, IoCapable<T>, and IoKnownSize
trait hierarchy for sharing a common interface supporting offset
validation and bound-checking logic between I/O backends.
- Refactor MMIO to use the common I/O backend infrastructure
- Misc:
- Add __rust_helper annotations to C helpers for inlining into
Rust code
- Use "kernel vertical" style for imports
- Replace kernel::c_str! with C string literals
- Update ARef imports to use sync::aref
- Use pin_init::zeroed() for struct auxiliary_device_id and
debugfs file_operations initialization
- Use LKMM atomic types in debugfs doc-tests
- Various minor comment and documentation fixes
- PCI:
- Implement PCI configuration space accessors using the common I/O
backend infrastructure
- Document pci::Bar device endianness assumptions
- SoC:
- Abstractions for struct soc_device and struct soc_device_attribute
- Sample driver for soc::Device"

Pull PCI updates from Bjorn Helgaas:
"Enumeration:
- Don't try to enable Extended Tags on VFs since that bit is Reserved
and causes misleading log messages (Håkon Bugge)
- Initialize Endpoint Read Completion Boundary to match Root Port,
regardless of ACPI _HPX (Håkon Bugge)
- Apply _HPX PCIe Setting Record only to AER configuration, and only
when OS owns PCIe hotplug but not AER, to avoid clobbering Extended
Tag and Relaxed Ordering settings (Håkon Bugge)
Resource management:
- Move CardBus code to setup-cardbus.c and only build it when
CONFIG_CARDBUS is set (Ilpo Järvinen)
- Fix bridge window alignment with optional resources, where
additional alignment requirement was previously lost (Ilpo
Järvinen)
- Stop over-estimating bridge window size since they are now assigned
without any gaps between them (Ilpo Järvinen)
- Increase resource MAX_IORES_LEVEL to avoid /proc/iomem flattening
for nested bridges and endpoints (Ilpo Järvinen)
- Add pbus_mem_size_optional() to handle sizes of optional resources
(SR-IOV VF BARs, expansion ROMs, bridge windows) (Ilpo Järvinen)
- Don't claim disabled bridge windows to avoid spurious claim
failures (Ilpo Järvinen)
Driver binding:
- Fix device reference leak in pcie_port_remove_service() (Uwe
Kleine-König)
- Move pcie_port_bus_match() and pcie_port_bus_type to PCIe-specific
portdrv.c (Uwe Kleine-König)
- Convert portdrv to use pcie_port_bus_type.probe() and .remove()
callbacks so .probe() and .remove() can eventually be removed from
struct device_driver (Uwe Kleine-König)
Error handling:
- Clear stale errors on reporting agents upon probe so they don't
look like recent errors (Lukas Wunner)
- Add generic RAS tracepoint for hotplug events (Shuai Xue)
- Add RAS tracepoint for link speed changes (Shuai Xue)
Power management:
- Avoid redundant delay on transition from D3hot to D3cold if the
device was already in D3hot (Brian Norris)
- Prevent runtime suspend until devices are fully initialized to
avoid saving incompletely configured device state (Brian Norris)
Power control:
- Add power_on/off callbacks with generic signature to pwrseq,
tc9563, and slot drivers so they can be used by pwrctrl core
(Manivannan Sadhasivam)
- Add PCIe M.2 connector support to the slot pwrctrl driver
(Manivannan Sadhasivam)
- Switch to pwrctrl interfaces to create, destroy, and power on/off
devices, calling them from host controller drivers instead of the
PCI core (Manivannan Sadhasivam)
- Drop qcom .assert_perst() callbacks since this is now done by the
controller driver instead of the pwrctrl driver (Manivannan
Sadhasivam)
Virtualization:
- Remove an incorrect unlock in pci_slot_trylock() error handling
(Jinhui Guo)
- Lock the bridge device for slot reset (Keith Busch)
- Enable ACS after IOMMU configuration on OF platforms so ACS is
enabled an all devices; previously the first device enumerated
(typically a Root Port) didn't have ACS enabled (Manivannan
Sadhasivam)
- Disable ACS Source Validation for IDT 0x80b5 and 0x8090 switches to
work around hardware erratum; previously ACS SV was only
temporarily disabled, which worked for enumeration but not after
reset (Manivannan Sadhasivam)
Peer-to-peer DMA:
- Release per-CPU pgmap ref when vm_insert_page() fails to avoid hang
when removing the PCI device (Hou Tao)
- Remove incorrect p2pmem_alloc_mmap() warning about page refcount
(Hou Tao)
Endpoint framework:
- Add configfs sub-groups synchronously to avoid NULL pointer
dereference when racing with removal (Liu Song)
- Fix swapped parameters in pci_{primary/secondary}_epc_epf_unlink()
functions (Manikanta Maddireddy)
- Add DT binding and driver support for SA8255p Endpoint being

- Parse PERST# from all PCIe bridge nodes for future platforms that
will have PERST# in Switch Downstream Ports as well as in Root
Ports (Manivannan Sadhasivam)
Renesas RZ/G3S PCIe controller driver:
- Use pci_generic_config_write() since the writability provided by
the custom wrapper is unnecessary (Claudiu Beznea)
SOPHGO PCIe controller driver:
- Disable ASPM L0s and L1 on Sophgo 2044 PCIe Root Ports (Inochi
Amaoto)
Synopsys DesignWare PCIe controller driver:
- Extend PCI_FIND_NEXT_CAP() and PCI_FIND_NEXT_EXT_CAP() to return a
pointer to the preceding Capability, to allow removal of
Capabilities that are advertised but not fully implemented (Qiang
Yu)
- Remove MSI and MSI-X Capabilities in platforms that can't support
them, so the PCI core automatically falls back to INTx (Qiang Yu)
- Add ASPM L1.1 and L1.2 Substates context to debugfs ltssm_status
for drivers that support this (Shawn Lin)
- Skip PME_Turn_Off broadcast and L2/L3 transition during suspend if
link is not up to avoid an unnecessary timeout (Manivannan
Sadhasivam)
- Revert dw-rockchip, qcom, and DWC core changes that used link-up
IRQs to trigger enumeration instead of waiting for link to be up
because the PCI core doesn't allocate bus number space for
hierarchies that might be attached (Niklas Cassel)
- Make endpoint iATU entry for MSI permanent instead of programming
it dynamically, which is slow and racy with respect to other
concurrent traffic, e.g., eDMA (Koichiro Den)
- Use iMSI-RX MSI target address when possible to fix endpoints using
32-bit MSI (Shawn Lin)
- Allow DWC host controller driver probe to continue if device is not
found or found but inactive; only fail when there's an error with
the link (Manivannan Sadhasivam)
- For controllers like NXP i.MX6QP and i.MX7D, where LTSSM registers
are not accessible after PME_Turn_Off, simply wait 10ms instead of
polling for L2/L3 Ready (Richard Zhu)
- Use multiple iATU entries to map large bridge windows and DMA
ranges when necessary instead of failing (Samuel Holland)
- Add EPC dynamic_inbound_mapping feature bit for Endpoint
Controllers that can update BAR inbound address translation without
requiring EPF driver to clear/reset the BAR first, and advertise it
for DWC-based Endpoints (Koichiro Den)
- Add EPC subrange_mapping feature bit for Endpoint Controllers that
can map multiple independent inbound regions in a single BAR,
implement subrange mapping, advertise it for DWC-based Endpoints,
and add Endpoint selftests for it (Koichiro Den)
- Make resizable BARs work for Endpoint multi-PF configurations;
previously it only worked for PF 0 (Aksh Garg)
- Fix Endpoint non-PF 0 support for BAR configuration, ATU mappings,
and Address Match Mode (Aksh Garg)
- Set up iATU when ECAM is enabled; previously IO and MEM outbound
windows weren't programmed, and ECAM-related iATU entries weren't
restored after suspend/resume, so config accesses failed (Krishna
Chaitanya Chundru)

- The percpu sheaves caching layer was introduced as opt-in in 6.18 and
now we enable it for all caches and remove the previous cpu (partial)
slab caching mechanism.
Besides the lower locking overhead and much more likely fastpath when
freeing, this removes the rather complicated code related to the cpu
slab lockless fastpaths (using this_cpu_try_cmpxchg128/64) and all
its complications for PREEMPT_RT or kmalloc_nolock().
The lockless slab freelist+counters update operation using
try_cmpxchg128/64 remains and is crucial for freeing remote NUMA
objects, and to allow flushing objects from sheaves to slabs mostly
without the node list_lock (Vlastimil Babka)
- Eliminate slabobj_ext metadata overhead when possible. Instead of
using kmalloc() to allocate the array for memcg and/or allocation
profiling tag pointers, use leftover space in a slab or per-object
padding due to alignment (Harry Yoo)

sched/mmcid: Don't assume CID is CPU owned on mode switch
Shinichiro reported a KASAN UAF, which is actually an out of bounds access
in the MMCID management code.
CPU0 CPU1
T1 runs in userspace
T0: fork(T4) -> Switch to per CPU CID mode
fixup() set MM_CID_TRANSIT on T1/CPU1
T4 exit()
T3 exit()
T2 exit()
T1 exit() switch to per task mode
---> Out of bounds access.
As T1 has not scheduled after T0 set the TRANSIT bit, it exits with the
TRANSIT bit set. sched_mm_cid_remove_user() clears the TRANSIT bit in
the task and drops the CID, but it does not touch the per CPU storage.
That's functionally correct because a CID is only owned by the CPU when
the ONCPU bit is set, which is mutually exclusive with the TRANSIT flag.
Now sched_mm_cid_exit() assumes that the CID is CPU owned because the
prior mode was per CPU. It invokes mm_drop_cid_on_cpu() which clears the
not set ONCPU bit and then invokes clear_bit() with an insanely large
bit number because TRANSIT is set (bit 29).
Prevent that by actually validating that the CID is CPU owned in
mm_drop_cid_on_cpu().

Although 1394 OHCI specification does not impose any restriction on
the memory size dedicated to these DMA contexts, 1394 OHCI PCI driver
allocates pages for convenience when mapping them into either kernel
space or userspace VMA. The driver previously used dma_alloc_pages()
for both page allocation and mapping creation, even though this
kernel API is rarely used. Following discussions questioning the
page-oriented kernel API in the DMA layer, the driver has been
refactored to avoid using this API. In addition, the use of private
members in the allocated pages has been removed following
long-standing concern.
- Allocate variable-sized buffer for isochronous context header
1394 OHCI PCI driver previously allocated a single page for
isochronous context header. As a result, the buffer size for the
header was fixed to PAGE_SIZE, which imposed a limitation on IEC
61883-1/6 packet streaming engine. Consequently, the ALSA PCM devices
provided by drivers for audio and music units in IEEE 1394 bus were
constrained in the maximum size of buffer period (64 ms in most
cases). This limitation is resolved by dynamically allocating the
header buffer with an arbitrary size.

"There are two new drivers and some changes to GPIO core but mostly
just GPIO driver updates across a wide array of files, adding support
for new models as well as various refactoring changes. Nothing
controversial and everything has spent a good measure of time in
linux-next.
GPIOLIB core:
- shrink the GPIO bus driver stub code
- rework software node support for "undefined" software nodes
- provide and use devm_fwnode_gpiod_get_optional()
- only compile the OF quirk for MT2701 when needed
New drivers:
- add the GPIO driver for ROHM bd72720
- add the gpio-line-mux driver providing 1-to-many mapping for a
single real GPIO
Driver changes:
- refactor gpio-pca9570: use lock guard, add missing headers, use
devres consistently
- add support for a new model (G7 Aspeed sgpiom) to the aspeed-sgpio
driver along with some prerequisite refactoring
- use device_get_match_data() where applicable and save some lines
- add support for more models to gpio-cadence
- add the compatible property to reset-gpio and use it in shared GPIO
management
- drop unnecessary use of irqd_get_trigger_type() in gpio-max77759
- add support for a new variant to gpio-pca953x
- extend build coverage with COMPILE_TEST for more drivers
- constify configfs structures in gpio-sim and gpio-virtuser
- add support for the K3 SoC to gpio-spacemit
- implement the missing .get_direction() callback in gpio-max77620
- add support for Tegra264 to gpio-tegra186
- drop unneeded MODULE_ALIAS() from gpio-menz127
DT bindings:
- document support for the opencores GPIO controller in gpio-mmio
- document new variants for gpio-pca953x
Documentation:
- extensively describe interrupt source detection for gpio-pca953x
and add more models to the list of supported variants"

KVM mediated PMU support for 6.20
Add support for mediated PMUs, where KVM gives the guest full ownership of PMU
hardware (contexted switched around the fastpath run loop) and allows direct
access to data MSRs and PMCs (restricted by the vPMU model), but intercepts
access to control registers, e.g. to enforce event filtering and to prevent the
guest from profiling sensitive host state.
To keep overall complexity reasonable, mediated PMU usage is all or nothing
for a given instance of KVM (controlled via module param). The Mediated PMU
is disabled default, partly to maintain backwards compatilibity for existing
setup, partly because there are tradeoffs when running with a mediated PMU that
may be non-starters for some use cases, e.g. the host loses the ability to
profile guests with mediated PMUs, the fastpath run loop is also a blind spot,
entry/exit transitions are more expensive, etc.
Versus the emulated PMU, where KVM is "just another perf user", the mediated
PMU delivers more accurate profiling and monitoring (no risk of contention and
thus dropped events), with significantly less overhead (fewer exits and faster
emulation/programming of event selectors) E.g. when running Specint-2017 on
a single-socket Sapphire Rapids with 56 cores and no-SMT, and using perf from
within the guest:
Perf command:
a. basic-sampling: perf record -F 1000 -e 6-instructions -a --overwrite
b. multiplex-sampling: perf record -F 1000 -e 10-instructions -a --overwrite

KVM x86 APIC-ish changes for 6.20
- Fix a benign bug where KVM could use the wrong memslots (ignored SMM) when
creating a vCPU-specific mapping of guest memory.
- 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 burying the
RTC shenanigans behind CONFIG_KVM_IOAPIC=y.
- Bury all of ioapic.h and KVM_IRQCHIP_KERNEL behind CONFIG_KVM_IOAPIC=y.
- Add a regression test for recent APICv update fixes.
- 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.
- 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.

KVM guest_memfd changes for 6.20
- Remove kvm_gmem_populate()'s preparation tracking and half-baked hugepage
handling, and instead rely on SNP (the only user of the tracking) to do its
own tracking 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 a non-existent usecase (and because
in-place conversion 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.

Pull spi updates from Mark Brown:
"The highlight here is that David Lechner has added support for
multi-lane SPI devices. Unlike the existing dual/quad SPI support this
is for devices (typically ADCs/DACs) which support multiple
independent data streams over multiple data lanes, instead of sending
one data stream N times as fast they simultaneously transfer N
different data streams.
This is very similar to the case where multiple devices are grouped
together but in this case it's a single device in a way that's visible
to software.
Otherwise there's been quite a bit of work on existing drivers, both
cleanup and feature improvement, and a reasonable collection of new
drivers.
- Support for multi-lane SPI devices
- Preparatory work for some memory mapped flash improvements that
will happen in the MTD subsystem
- Several conversions to fwnode APIs
- A bunch of cleanup and hardening work on the ST drivers
- Support for DMA mode on Renesas RZV2H and i.MX target mode
- Support for ATCSPI200, AXIADO AX300, NXP XPI and Renesas RZ/N1"
