Pull tracing tooling updates from Steven Rostedt:
- Add cgroup support for rtla via the -C option
- Add --house-keeping option that tells rtla where to place the
housekeeping threads

When using pm_nl_ctl to validate userspace path-manager's behaviours, it
was failing on 32-bit architectures ~half of the time.
pm_nl_ctl was not reporting any error but the command was not doing what
it was expected to do. As a result, the expected linked event was not
triggered after and the test failed.
This is due to the fact the token given in argument to the application
was parsed as an integer with atoi(): in a 32-bit arch, if the number
was bigger than INT_MAX, 2147483647 was used instead.
This can simply be fixed by using strtoul() instead of atoi().
The errors have been seen "by chance" when manually looking at the
results from LKFT.

MPTCP selftests are using TCP SYN Cookies for quite a while now, since
v5.9.
Some CIs don't have this config option enabled and this is causing
issues in the tests:
# ns1 MPTCP -> ns1 (10.0.1.1:10000 ) MPTCP (duration 167ms) sysctl: cannot stat /proc/sys/net/ipv4/tcp_syncookies: No such file or directory
# [ OK ]./mptcp_connect.sh: line 554: [: -eq: unary operator expected
There is no impact in the results but the test is not doing what it is
supposed to do.

When an error was detected when checking the marks, a message was
correctly printed mentioning the error but followed by another one
saying everything was OK and the selftest was not marked as failed as
expected.
Now the 'ret' variable is directly set to 1 in order to make sure the
exit is done with an error, similar to what is done in other functions.
While at it, the error is correctly propagated to the caller.

In case of "external" errors when preparing the environment for the
TProxy tests, the subtests were marked as skipped.
This is fine but it means these errors are ignored. On MPTCP Public CI,
we do want to catch such issues and mark the selftest as failed if there
are such issues. We can then use mptcp_lib_fail_if_expected_feature()
helper that has been recently added to fail if needed.

Pull kvm updates from Paolo Bonzini:
"ARM64:
- Eager page splitting optimization for dirty logging, optionally
allowing for a VM to avoid the cost of hugepage splitting in the
stage-2 fault path.
- Arm FF-A proxy for pKVM, allowing a pKVM host to safely interact
with services that live in the Secure world. pKVM intervenes on
FF-A calls to guarantee the host doesn't misuse memory donated to
the hyp or a pKVM guest.
- Support for running the split hypervisor with VHE enabled, known as
'hVHE' mode. This is extremely useful for testing the split
hypervisor on VHE-only systems, and paves the way for new use cases
that depend on having two TTBRs available at EL2.
- Generalized framework for configurable ID registers from userspace.
KVM/arm64 currently prevents arbitrary CPU feature set
configuration from userspace, but the intent is to relax this
limitation and allow userspace to select a feature set consistent
with the CPU.
- Enable the use of Branch Target Identification (FEAT_BTI) in the
hypervisor.
- Use a separate set of pointer authentication keys for the
hypervisor when running in protected mode, as the host is untrusted
at runtime.
- Ensure timer IRQs are consistently released in the init failure
paths.
- Avoid trapping CTR_EL0 on systems with Enhanced Virtualization
Traps (FEAT_EVT), as it is a register commonly read from userspace.
- Erratum workaround for the upcoming AmpereOne part, which has
broken hardware A/D state management.

- Redirect AMO load/store misaligned traps to KVM guest
- Trap-n-emulate AIA in-kernel irqchip for KVM guest

Packets bound for peers can queue up prior to the device private key
being set. For example, if persistent keepalive is set, a packet is
queued up to be sent as soon as the device comes up. However, if the
private key hasn't been set yet, the handshake message never sends, and
no timer is armed to retry, since that would be pointless.
But, if a user later sets a private key, the expectation is that those
queued packets, such as a persistent keepalive, are actually sent. So
adjust the configuration logic to account for this edge case, and add a
test case to make sure this works.
Maxim noticed this with a wg-quick(8) config to the tune of:
[Interface]
PostUp = wg set %i private-key somefile
[Peer]
PublicKey = ...
Endpoint = ...
PersistentKeepalive = 25
Here, the private key gets set after the device comes up using a PostUp
script, triggering the bug.

Pull CXL updates from Dan Williams:
"The highlights in terms of new functionality are support for the
standard CXL Performance Monitor definition that appeared in CXL 3.0,
support for device sanitization (wiping all data from a device),
secure-erase (re-keying encryption of user data), and support for
firmware update. The firmware update support is notable as it reuses
the simple sysfs_upload interface to just cat(1) a blob to a sysfs
file and pipe that to the device.
Additionally there are a substantial number of cleanups and
reorganizations to get ready for RCH error handling (RCH == Restricted
CXL Host == current shipping hardware generation / pre CXL-2.0
topologies) and type-2 (accelerator / vendor specific) devices.
For vendor specific devices they implement a subset of what the
generic type-3 (generic memory expander) driver expects. As a result
the rework decouples optional infrastructure from the core driver
context.
For RCH topologies, where the specification working group did not want
to confuse pre-CXL-aware operating systems, many of the standard
registers are hidden which makes support standard bus features like
AER (PCIe Advanced Error Reporting) difficult. The rework arranges for
the driver to help the PCI-AER core. Bjorn is on board with this
direction but a late regression disocvery means the completion of this
functionality needs to cook a bit longer, so it is code
reorganizations only for now.
Summary:
- Add infrastructure for supporting background commands along with
support for device sanitization and firmware update
- Introduce a CXL performance monitoring unit driver based on the
common definition in the specification.
- Land some preparatory cleanup and refactoring for the anticipated
arrival of CXL type-2 (accelerator devices) and CXL RCH (CXL-v1.1
topology) error handling.
- Rework CPU cache management with respect to region configuration
(device hotplug or other dynamic changes to memory interleaving)
- Fix region reconfiguration vs CXL decoder ordering rules"

Pull perf tools updates from Namhyung Kim:
"Internal cleanup:
- Refactor PMU data management to handle hybrid systems in a generic
way.
Do more work in the lexer so that legacy event types parse more
easily. A side-effect of this is that if a PMU is specified,
scanning sysfs is avoided improving start-up time.
- Fix hybrid metrics, for example, the TopdownL1 works for both
performance and efficiency cores on Intel machines. To support
this, sort and regroup events after parsing.
- Add reference count checking for the 'thread' data structure.
- Lots of fixes for memory leaks in various places thanks to the ASAN
and Ian's refcount checker.
- Reduce the binary size by replacing static variables with local or
dynamically allocated memory.
- Introduce shared_mutex for annotate data to reduce memory
footprint.
- Make filesystem access library functions more thread safe.
Test:
- Organize cpu_map tests into a single suite.
- Add metric value validation test to check if the values are within
correct value ranges.
- Add perf stat stdio output test to check if event and metric names
match.
- Add perf data converter JSON output test.
- Fix a lot of issues reported by shellcheck(1). This is a
preparation to enable shellcheck by default.
- Make the large x86 new instructions test optional at build time
using EXTRA_TESTS=1.
- Add a test for libpfm4 events.
perf script:
- Add 'dsoff' outpuf field to display offset from the DSO.
$ perf script -F comm,pid,event,ip,dsoff

- Adjust width for large PID/TID values.
perf report:
- Robustify reading addr2line output for srcline by checking sentinel
output before the actual data and by using timeout of 1 second.
- Allow config terms (like 'name=ABC') with breakpoint events.
$ perf record -e mem:0x55feb98dd169:x/name=breakpoint/ -p 19646 -- sleep 1
perf annotate:
- Handle x86 instruction suffix like 'l' in 'movl' generally.
- Parse instruction operands properly even with a whitespace. This is
needed for llvm-objdump output.
- Support RISC-V binutils lookup using the triplet prefixes.
- Add '<' and '>' key to navigate to prev/next symbols in TUI.
- Fix instruction association and parsing for LoongArch.

Pull probes updates from Masami Hiramatsu:
- fprobe: Pass return address to the fprobe entry/exit callbacks so
that the callbacks don't need to analyze pt_regs/stack to find the
function return address.
- kprobe events: cleanup usage of TPARG_FL_FENTRY and TPARG_FL_RETURN
flags so that those are not set at once.
- fprobe events:
- Add a new fprobe events for tracing arbitrary function entry and
exit as a trace event.
- Add a new tracepoint events for tracing raw tracepoint as a
trace event. This allows user to trace non user-exposed
tracepoints.
- Move eprobe's event parser code into probe event common file.
- Introduce BTF (BPF type format) support to kernel probe (kprobe,
fprobe and tracepoint probe) events so that user can specify
traced function arguments by name. This also applies the type of
argument when fetching the argument.
- Introduce '$arg*' wildcard support if BTF is available. This
expands the '$arg*' meta argument to all function argument
automatically.
- Check the return value types by BTF. If the function returns
'void', '$retval' is rejected.
- Add some selftest script for fprobe events, tracepoint events
and BTF support.
- Update documentation about the fprobe events.
- Some fixes for above features, document and selftests.
- selftests for ftrace (in addition to the new fprobe events):
- Add a test case for multiple consecutive probes in a function
which checks if ftrace based kprobe, optimized kprobe and normal
kprobe can be defined in the same target function.
- Add a test case for optimized probe, which checks whether kprobe
can be optimized or not.

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull tracing updates from Steven Rostedt:
- Add new feature to have function graph tracer record the return
value. Adds a new option: funcgraph-retval ; when set, will show the
return value of a function in the function graph tracer.
- Also add the option: funcgraph-retval-hex where if it is not set, and
the return value is an error code, then it will return the decimal of
the error code, otherwise it still reports the hex value.
- Add the file /sys/kernel/tracing/osnoise/per_cpu/cpu<cpu>/timerlat_fd
That when a application opens it, it becomes the task that the timer
lat tracer traces. The application can also read this file to find
out how it's being interrupted.
- Add the file /sys/kernel/tracing/available_filter_functions_addrs
that works just the same as available_filter_functions but also shows
the addresses of the functions like kallsyms, except that it gives
the address of where the fentry/mcount jump/nop is. This is used by
BPF to make it easier to attach BPF programs to ftrace hooks.
- Replace strlcpy with strscpy in the tracing boot code.

"Fix user event write on buffer disabled.
The user events write currently returns the size of what was supposed
to be written when tracing is disabled and nothing was written.
Instead, behave like trace_marker and return -EBADF, as that is what
is returned if a file is opened for read only, and a write is
performed on it. Writing to the buffer that is disabled is like trying
to write to a file opened for read only, as the buffer still can be
read, but just not written to.
This also includes test cases for this use case"

The objtool merge in commit 6f612579be9d ("Merge tag 'objtool-core ...")
generated a semantic conflict that was not resolved.
The btrfs_assertfail() entry was removed from the noreturn list in
commit b831306b3b7d ("btrfs: print assertion failure report and stack
trace from the same line") because btrfs_assertfail() was changed from a
noreturn function into a macro.
The noreturn list was then moved from check.c to noreturns.h in commit
6245ce4ab670 ("objtool: Move noreturn function list to separate file"),
and should be removed from that post-merge as well.
Do it explicitly.

Pull gpio updates from Bartosz Golaszewski:
"We have two new drivers, some improvements to the core code, lots of
different updates to existing GPIO drivers and some dt-bindings on
top.
There's nothing controversial in here and almost everything has been
in next for more than a week (95% a lot longer than this). The only
thing that has spent less time in next is a new driver so no risk of
regressions.
The single merge pulls in changes that remove all usage of global GPIO
numbers from arch/arm/mach-omap.
Core GPIO library:
- remove unused symbols
- don't spam the kernel log with messages about hogs
- remove old sysfs API cruft
- improve handling of GPIO masks
New drivers:
- add a driver for the BlueField-3 GPIO controller
- add GPIO support for the TPS65219 PMIC
Driver improvements:
- extend the gpio-aggregator driver to support ramp-up/ramp-down
delay
- remove unnecessary CONFIG_OF guards from gpio-aggregator
- readability improvements in gpio-tangier
- switch i2c drivers back to using probe() now that it's been
converted in the i2c subsystem to not taking the id parameter
- remove unused inclusions of of_gpio.h in several drivers
- make pm ops static in gpio-davinci and fix a comment
- use more devres in drivers to shrink and simplify the code
- add missing include in gpio-sa1100
- add HAS_IOPORT KConfig dependency where needed
- add permissions checks before accessing pins in gpio-tegra186
- convert the gpio-zynq driver to using immutable irqchips
- preserve output settings set by the bootloader in gpio-mpc8xxx
Selftests:
- tweak the variable naming in script tests
Device tree updates:
- convert gpio-mmio and gpio-stmpe to YAML
- add parsing of GPIO hogs to gpio-vf610
- add bindings for the Cirrus EP93xx GPIO controller
- add gpio-line-names property to the gpio-pca9570 bindings
- extend the binding for x-powers,axp209 with another block"

Pull networking changes from Jakub Kicinski:
"WiFi 7 and sendpage changes are the biggest pieces of work for this
release. The latter will definitely require fixes but I think that we
got it to a reasonable point.
Core:
- Rework the sendpage & splice implementations
Instead of feeding data into sockets page by page extend sendmsg
handlers to support taking a reference on the data, controlled by a
new flag called MSG_SPLICE_PAGES
Rework the handling of unexpected-end-of-file to invoke an
additional callback instead of trying to predict what the right
combination of MORE/NOTLAST flags is
Remove the MSG_SENDPAGE_NOTLAST flag completely
- Implement SCM_PIDFD, a new type of CMSG type analogous to
SCM_CREDENTIALS, but it contains pidfd instead of plain pid
- Enable socket busy polling with CONFIG_RT
- Improve reliability and efficiency of reporting for ref_tracker
- Auto-generate a user space C library for various Netlink families
Protocols:
- Allow TCP to shrink the advertised window when necessary, prevent
sk_rcvbuf auto-tuning from growing the window all the way up to
tcp_rmem[2]
- Use per-VMA locking for "page-flipping" TCP receive zerocopy
- Prepare TCP for device-to-device data transfers, by making sure
that payloads are always attached to skbs as page frags
- Make the backoff time for the first N TCP SYN retransmissions
linear. Exponential backoff is unnecessarily conservative
- Create a new MPTCP getsockopt to retrieve all info
(MPTCP_FULL_INFO)
- Avoid waking up applications using TLS sockets until we have a full
record
- Allow using kernel memory for protocol ioctl callbacks, paving the
way to issuing ioctls over io_uring
- Add nolocalbypass option to VxLAN, forcing packets to be fully
encapsulated even if they are destined for a local IP address
- Make TCPv4 use consistent hash in TIME_WAIT and SYN_RECV. Ensure
in-kernel ECMP implementation (e.g. Open vSwitch) select the same
link for all packets. Support L4 symmetric hashing in Open vSwitch
- PPPoE: make number of hash bits configurable
- Allow DNS to be overwritten by DHCPACK in the in-kernel DHCP client
(ipconfig)
- Add layer 2 miss indication and filtering, allowing higher layers
(e.g. ACL filters) to make forwarding decisions based on whether
packet matched forwarding state in lower devices (bridge)
- Support matching on Connectivity Fault Management (CFM) packets
- Hide the "link becomes ready" IPv6 messages by demoting their
printk level to debug
- HSR: don't enable promiscuous mode if device offloads the proto
- Support active scanning in IEEE 802.15.4
- Continue work on Multi-Link Operation for WiFi 7
BPF:
- Add precision propagation for subprogs and callbacks. This allows
maintaining verification efficiency when subprograms are used, or
in fact passing the verifier at all for complex programs,
especially those using open-coded iterators
- Improve BPF's {g,s}setsockopt() length handling. Previously BPF
assumed the length is always equal to the amount of written data.
But some protos allow passing a NULL buffer to discover what the
output buffer *should* be, without writing anything
- Accept dynptr memory as memory arguments passed to helpers
- Add routing table ID to bpf_fib_lookup BPF helper
- Support O_PATH FDs in BPF_OBJ_PIN and BPF_OBJ_GET commands
- Drop bpf_capable() check in BPF_MAP_FREEZE command (used to mark
maps as read-only)
- Show target_{obj,btf}_id in tracing link fdinfo
- Addition of several new kfuncs (most of the names are
self-explanatory):
- Add a set of new dynptr kfuncs: bpf_dynptr_adjust(),
bpf_dynptr_is_null(), bpf_dynptr_is_rdonly(), bpf_dynptr_size()
and bpf_dynptr_clone().
- bpf_task_under_cgroup()
- bpf_sock_destroy() - force closing sockets
- bpf_cpumask_first_and(), rework bpf_cpumask_any*() kfuncs
Netfilter:
- Relax set/map validation checks in nf_tables. Allow checking
presence of an entry in a map without using the value
- Increase ip_vs_conn_tab_bits range for 64BIT builds
- Allow updating size of a set
- Improve NAT tuple selection when connection is closing
Driver API:
- Integrate netdev with LED subsystem, to allow configuring HW
"offloaded" blinking of LEDs based on link state and activity
(i.e. packets coming in and out)
- Support configuring rate selection pins of SFP modules
- Factor Clause 73 auto-negotiation code out of the drivers, provide
common helper routines
- Add more fool-proof helpers for managing lifetime of MDIO devices
associated with the PCS layer
- Allow drivers to report advanced statistics related to Time Aware
scheduler offload (taprio)
- Allow opting out of VF statistics in link dump, to allow more VFs
to fit into the message
- Split devlink instance and devlink port operations

Pull sysctl updates from Luis Chamberlain:
"The changes for sysctl are in line with prior efforts to stop usage of
deprecated routines which incur recursion and also make it hard to
remove the empty array element in each sysctl array declaration.
The most difficult user to modify was parport which required a bit of
re-thinking of how to declare shared sysctls there, Joel Granados has
stepped up to the plate to do most of this work and eventual removal
of register_sysctl_table(). That work ended up saving us about 1465
bytes according to bloat-o-meter. Since we gained a few bloat-o-meter
karma points I moved two rather small sysctl arrays from
kernel/sysctl.c leaving us only two more sysctl arrays to move left.
Most changes have been tested on linux-next for about a month. The
last straggler patches are a minor parport fix, changes to the sysctl
kernel selftest so to verify correctness and prevent regressions for
the future change he made to provide an alternative solution for the
special sysctl mount point target which was using the now deprecated
sysctl child element.
This is all prep work to now finally be able to remove the empty array
element in all sysctl declarations / registrations which is expected
to save us a bit of bytes all over the kernel. That work will be
tested early after v6.5-rc1 is out"

Pull module updates from Luis Chamberlain:
"The changes queued up for modules are pretty tame, mostly code removal
of moving of code.
Only two minor functional changes are made, the only one which stands
out is Sebastian Andrzej Siewior's simplification of module reference
counting by removing preempt_disable() and that has been tested on
linux-next for well over a month without no regressions.
I'm now, I guess, also a kitchen sink for some kallsyms changes"
[ There was a mis-communication about the concurrent module load changes
that I had expected to come through Luis despite me authoring the
patch. So some of the module updates were left hanging in the email
ether, and I just committed them separately.
It's my bad - I should have made it more clear that I expected my
own patches to come through the module tree too. Now they missed
linux-next, but hopefully that won't cause any issues - Linus ]

Pull hardening updates from Kees Cook:
"There are three areas of note:
A bunch of strlcpy()->strscpy() conversions ended up living in my tree
since they were either Acked by maintainers for me to carry, or got
ignored for multiple weeks (and were trivial changes).
The compiler option '-fstrict-flex-arrays=3' has been enabled
globally, and has been in -next for the entire devel cycle. This
changes compiler diagnostics (though mainly just -Warray-bounds which
is disabled) and potential UBSAN_BOUNDS and FORTIFY _warning_
coverage. In other words, there are no new restrictions, just
potentially new warnings. Any new FORTIFY warnings we've seen have
been fixed (usually in their respective subsystem trees). For more
details, see commit df8fc4e934c12b.
The under-development compiler attribute __counted_by has been added
so that we can start annotating flexible array members with their
associated structure member that tracks the count of flexible array
elements at run-time. It is possible (likely?) that the exact syntax
of the attribute will change before it is finalized, but GCC and Clang
are working together to sort it out. Any changes can be made to the
macro while we continue to add annotations.
As an example of that last case, I have a treewide commit waiting with
such annotations found via Coccinelle:
https://git.kernel.org/linus/adc5b3cb48a049563dc673f348eab7b6beba8a9b
Also see commit dd06e72e68bcb4 for more details.
Summary:
- Fix KMSAN vs FORTIFY in strlcpy/strlcat (Alexander Potapenko)
- Convert strreplace() to return string start (Andy Shevchenko)
- Flexible array conversions (Arnd Bergmann, Wyes Karny, Kees Cook)
- Add missing function prototypes seen with W=1 (Arnd Bergmann)
- Fix strscpy() kerndoc typo (Arne Welzel)
- Replace strlcpy() with strscpy() across many subsystems which were
either Acked by respective maintainers or were trivial changes that
went ignored for multiple weeks (Azeem Shaikh)
- Remove unneeded cc-option test for UBSAN_TRAP (Nick Desaulniers)
- Add KUnit tests for strcat()-family
- Enable KUnit tests of FORTIFY wrappers under UML
- Add more complete FORTIFY protections for strlcat()
- Add missed disabling of FORTIFY for all arch purgatories.
- Enable -fstrict-flex-arrays=3 globally
- Tightening UBSAN_BOUNDS when using GCC
- Improve checkpatch to check for strcpy, strncpy, and fake flex
arrays
- Improve use of const variables in FORTIFY
- Add requested struct_size_t() helper for types not pointers

Pull landlock updates from Mickaël Salaün:
"Add support for Landlock to UML.
To do this, this fixes the way hostfs manages inodes according to the
underlying filesystem [1]. They are now properly handled as for other
filesystems, which enables Landlock support (and probably other
features).
This also extends Landlock's tests with 6 pseudo filesystems,
including hostfs"

Pull workqueue updates from Tejun Heo:
- Concurrency-managed per-cpu work items that hog CPUs and delay the
execution of other work items are now automatically detected and
excluded from concurrency management. Reporting on such work items
can also be enabled through a config option.
- Added tools/workqueue/wq_monitor.py which improves visibility into
workqueue usages and behaviors.
- Arnd's minimal fix for gcc-13 enum warning on 32bit compiles,
superseded by commit afa4bb778e48 in mainline.

Pull objtool updates from Ingo Molar:
"Build footprint & performance improvements:
- Reduce memory usage with CONFIG_DEBUG_INFO=y
In the worst case of an allyesconfig+CONFIG_DEBUG_INFO=y kernel,
DWARF creates almost 200 million relocations, ballooning objtool's
peak heap usage to 53GB. These patches reduce that to 25GB.
On a distro-type kernel with kernel IBT enabled, they reduce
objtool's peak heap usage from 4.2GB to 2.8GB.
These changes also improve the runtime significantly.
Debuggability improvements:
- Add the unwind_debug command-line option, for more extend unwinding
debugging output
- Limit unreachable warnings to once per function
- Add verbose option for disassembling affected functions
- Include backtrace in verbose mode
- Detect missing __noreturn annotations
- Ignore exc_double_fault() __noreturn warnings
- Remove superfluous global_noreturns entries
- Move noreturn function list to separate file
- Add __kunit_abort() to noreturns
Unwinder improvements:
- Allow stack operations in UNWIND_HINT_UNDEFINED regions
- drm/vmwgfx: Add unwind hints around RBP clobber
Cleanups:
- Move the x86 entry thunk restore code into thunk functions
- x86/unwind/orc: Use swap() instead of open coding it
- Remove unnecessary/unused variables
Fixes for modern stack canary handling"
