- Reorganize the architecture-optimized CRC32 and CRC-T10DIF code to be
directly accessible via the library API, instead of requiring the
crypto API. This is much simpler and more efficient.
- Convert some users such as ext4 to use the CRC32 library API instead
of the crypto API. More conversions like this will come later.
- Add a KUnit test that tests and benchmarks multiple CRC variants.
Remove older, less-comprehensive tests that are made redundant by
this.
- Add an entry to MAINTAINERS for the kernel's CRC library code. I'm
volunteering to maintain it. I have additional cleanups and
optimizations planned for future cycles.
These patches have been in linux-next since -rc1.

Pull power management updates from Rafael Wysocki:
"The majority of changes here are cpufreq updates which are dominated
by amd-pstate driver changes, like in the previous cycle. Moreover,
changes related to amd-pstate are also the majority of cpupower
utility updates.
Included are some pieces of new hardware support, like the addition of
Clearwater Forest processors support to intel_idle, new cpufreq driver
for Airoha SoCs, and Apple cpufreq driver extensions to support more
SoCs. The intel_pstate driver is also extended to be able to support
new platforms by using ACPI CPPC to compute scaling factors between
HWP performance states and frequency.

management code.

Kozlowski)

Core
----
- More core refactoring to reduce the RTNL lock contention,
including preparatory work for the per-network namespace RTNL lock,
replacing RTNL lock with a per device-one to protect NAPI-related
net device data and moving synchronize_net() calls outside such
lock.
- Extend drop reasons usage, adding net scheduler, AF_UNIX, bridge and
more specific TCP coverage.
- Reduce network namespace tear-down time by removing per-subsystems
synchronize_net() in tipc and sched.
- Add flow label selector support for fib rules, allowing traffic
redirection based on such header field.
Netfilter
---------
- Do not remove netdev basechain when last device is gone, allowing
netdev basechains without devices.
- Revisit the flowtable teardown strategy, dealing better with fin,
reset and re-open events.
- Scale-up IP-vs connection dumping by avoiding linear search on
each restart.
Protocols
---------
- A significant XDP socket refactor, consolidating and optimizing
several helpers into the core
- Better scaling of ICMP rate-limiting, by removing false-sharing in
inet peers handling.
- Introduces netlink notifications for multicast IPv4 and IPv6
address changes.
- Add ipsec support for IP-TFS/AggFrag encapsulation, allowing
aggregation and fragmentation of the inner IP.
- Add sysctl to configure TIME-WAIT reuse delay for TCP sockets,
to avoid local port exhaustion issues when the average connection
lifetime is very short.
- Support updating keys (re-keying) for connections using kernel
TLS (for TLS 1.3 only).
- Support ipv4-mapped ipv6 address clients in smc-r v2.
- Add support for jumbo data packet transmission in RxRPC sockets,
gluing multiple data packets in a single UDP packet.
- Support RxRPC RACK-TLP to manage packet loss and retransmission in
conjunction with the congestion control algorithm.
Driver API
----------
- Introduce a unified and structured interface for reporting PHY
statistics, exposing consistent data across different H/W via
ethtool.
- Make timestamping selectable, allow the user to select the desired
hwtstamp provider (PHY or MAC) administratively.
- Add support for configuring a header-data-split threshold (HDS)
value via ethtool, to deal with partial or buggy H/W implementation.
- Consolidate DSA drivers Energy Efficiency Ethernet support.
- Add EEE management to phylink, making use of the phylib
implementation.
- Add phylib support for in-band capabilities negotiation.
- Simplify how phylib-enabled mac drivers expose the supported
interfaces.
Tests and tooling
-----------------
- Make the YNL tool package-friendly to make it easier to deploy it
separately from the kernel.
- Increase TCP selftest coverage importing several packetdrill
test-cases.
- Regenerate the ethtool uapi header from the YNL spec,
to ease maintenance and future development.
- Add YNL support for decoding the link types used in net
self-tests, allowing a single build to run both net and
drivers/net.

Pull networking updates from Paolo Abeni:
"This is slightly smaller than usual, with the most interesting work
being still around RTNL scope reduction.
Core:
- More core refactoring to reduce the RTNL lock contention, including
preparatory work for the per-network namespace RTNL lock, replacing
RTNL lock with a per device-one to protect NAPI-related net device
data and moving synchronize_net() calls outside such lock.
- Extend drop reasons usage, adding net scheduler, AF_UNIX, bridge
and more specific TCP coverage.
- Reduce network namespace tear-down time by removing per-subsystems
synchronize_net() in tipc and sched.
- Add flow label selector support for fib rules, allowing traffic
redirection based on such header field.
Netfilter:
- Do not remove netdev basechain when last device is gone, allowing
netdev basechains without devices.
- Revisit the flowtable teardown strategy, dealing better with fin,
reset and re-open events.
- Scale-up IP-vs connection dumping by avoiding linear search on each
restart.
Protocols:
- A significant XDP socket refactor, consolidating and optimizing
several helpers into the core
- Better scaling of ICMP rate-limiting, by removing false-sharing in
inet peers handling.
- Introduces netlink notifications for multicast IPv4 and IPv6
address changes.
- Add ipsec support for IP-TFS/AggFrag encapsulation, allowing
aggregation and fragmentation of the inner IP.
- Add sysctl to configure TIME-WAIT reuse delay for TCP sockets, to
avoid local port exhaustion issues when the average connection
lifetime is very short.
- Support updating keys (re-keying) for connections using kernel TLS
(for TLS 1.3 only).
- Support ipv4-mapped ipv6 address clients in smc-r v2.
- Add support for jumbo data packet transmission in RxRPC sockets,
gluing multiple data packets in a single UDP packet.
- Support RxRPC RACK-TLP to manage packet loss and retransmission in
conjunction with the congestion control algorithm.
Driver API:
- Introduce a unified and structured interface for reporting PHY
statistics, exposing consistent data across different H/W via
ethtool.
- Make timestamping selectable, allow the user to select the desired
hwtstamp provider (PHY or MAC) administratively.
- Add support for configuring a header-data-split threshold (HDS)
value via ethtool, to deal with partial or buggy H/W
implementation.
- Consolidate DSA drivers Energy Efficiency Ethernet support.
- Add EEE management to phylink, making use of the phylib
implementation.
- Add phylib support for in-band capabilities negotiation.
- Simplify how phylib-enabled mac drivers expose the supported
interfaces.
Tests and tooling:
- Make the YNL tool package-friendly to make it easier to deploy it
separately from the kernel.
- Increase TCP selftest coverage importing several packetdrill
test-cases.
- Regenerate the ethtool uapi header from the YNL spec, to ease
maintenance and future development.

Merge tag 'lsm-pr-20250121' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm
Pull lsm updates from Paul Moore:
- Improved handling of LSM "secctx" strings through lsm_context struct
The LSM secctx string interface is from an older time when only one
LSM was supported, migrate over to the lsm_context struct to better
support the different LSMs we now have and make it easier to support
new LSMs in the future.
These changes explain the Rust, VFS, and networking changes in the
diffstat.
- Only build lsm_audit.c if CONFIG_SECURITY and CONFIG_AUDIT are
enabled
Small tweak to be a bit smarter about when we build the LSM's common
audit helpers.
- Check for absurdly large policies from userspace in SafeSetID
SafeSetID policies rules are fairly small, basically just "UID:UID",
it easy to impose a limit of KMALLOC_MAX_SIZE on policy writes which
helps quiet a number of syzbot related issues. While work is being
done to address the syzbot issues through other mechanisms, this is a
trivial and relatively safe fix that we can do now.
- Various minor improvements and cleanups
A collection of improvements to the kernel selftests, constification
of some function parameters, removing redundant assignments, and
local variable renames to improve readability.

- Have fprobes built on top of function graph infrastructure
The fprobe logic is an optimized kprobe that uses ftrace to attach to
functions when a probe is needed at the start or end of the function. The
fprobe and kretprobe logic implements a similar method as the function
graph tracer to trace the end of the function. That is to hijack the
return address and jump to a trampoline to do the trace when the function
exits. To do this, a shadow stack needs to be created to store the
original return address. Fprobes and function graph do this slightly
differently. Fprobes (and kretprobes) has slots per callsite that are
reserved to save the return address. This is fine when just a few points
are traced. But users of fprobes, such as BPF programs, are starting to add
many more locations, and this method does not scale.
The function graph tracer was created to trace all functions in the
kernel. In order to do this, when function graph tracing is started, every
task gets its own shadow stack to hold the return address that is going to
be traced. The function graph tracer has been updated to allow multiple
users to use its infrastructure. Now have fprobes be one of those users.
This will also allow for the fprobe and kretprobe methods to trace the
return address to become obsolete. With new technologies like CFI that
need to know about these methods of hijacking the return address, going
toward a solution that has only one method of doing this will make the
kernel less complex.
- Cleanup with guard() and free() helpers
There were several places in the code that had a lot of "goto out" in the
error paths to either unlock a lock or free some memory that was
allocated. But this is error prone. Convert the code over to use the
guard() and free() helpers that let the compiler unlock locks or free
memory when the function exits.
- Remove disabling of interrupts in the function graph tracer
When function graph tracer was first introduced, it could race with
interrupts and NMIs. To prevent that race, it would disable interrupts and
not trace NMIs. But the code has changed to allow NMIs and also
interrupts. This change was done a long time ago, but the disabling of
interrupts was never removed. Remove the disabling of interrupts in the
function graph tracer is it is not needed. This greatly improves its
performance.
- Allow the :mod: command to enable tracing module functions on the kernel
command line.
The function tracer already has a way to enable functions to be traced in
modules by writing ":mod:<module>" into set_ftrace_filter. That will
enable either all the functions for the module if it is loaded, or if it
is not, it will cache that command, and when the module is loaded that
matches <module>, its functions will be enabled. This also allows init
functions to be traced. But currently events do not have that feature.
Because enabling function tracing can be done very early at boot up
(before scheduling is enabled), the commands that can be done when
function tracing is started is limited. Having the ":mod:" command to
trace module functions as they are loaded is very useful. Update the
kernel command line function filtering to allow it.

Pull livepatching updates from Petr Mladek:
- Add a sysfs attribute showing the livepatch ordering
- Some code clean up
* tag 'livepatching-for-6.14' of git://git.kernel.org/pub/scm/linux/kernel/git/livepatching/livepatching:
selftests: livepatch: add test cases of stack_order sysfs interface
livepatch: Add stack_order sysfs attribute
selftests/livepatch: Replace hardcoded module name with variable in test-callbacks.sh
This just moves the existing tests under tools/pci to
tools/testing/selftests/pci_endpoint and adjusts the paths in Makefile
accordingly. Migration to Kselftest framework will be done in subsequent
commits.

Merge tag 'vfs-6.14-rc1.mount.v2' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs
Pull vfs mount updates from Christian Brauner:
- Add a mountinfo program to demonstrate statmount()/listmount()
Add a new "mountinfo" sample userland program that demonstrates how
to use statmount() and listmount() to get at the same info that
/proc/pid/mountinfo provides
- Remove pointless nospec.h include
- Prepend statmount.mnt_opts string with security_sb_mnt_opts()
Currently these mount options aren't accessible via statmount()
- Add new mount namespaces to mount namespace rbtree outside of the
namespace semaphore
- Lockless mount namespace lookup
Currently we take the read lock when looking for a mount namespace to
list mounts in. We can make this lockless. The simple search case can
just use a sequence counter to detect concurrent changes to the
rbtree
For walking the list of mount namespaces sequentially via nsfs we
keep a separate rcu list as rb_prev() and rb_next() aren't usable
safely with rcu. Currently there is no primitive for retrieving the
previous list member. To do this we need a new deletion primitive
that doesn't poison the prev pointer and a corresponding retrieval
helper
Since creating mount namespaces is a relatively rare event compared
with querying mounts in a foreign mount namespace this is worth it.
Once libmount and systemd pick up this mechanism to list mounts in
foreign mount namespaces this will be used very frequently
- Add extended selftests for lockless mount namespace iteration
- Add a sample program to list all mounts on the system, i.e., in
all mount namespaces
- Improve mount namespace iteration performance
Make finding the last or first mount to start iterating the mount
namespace from an O(1) operation and add selftests for iterating the
mount table starting from the first and last mount
- Use an xarray for the old mount id
While the ida does use the xarray internally we can use it explicitly
which allows us to increment the unique mount id under the xa lock.
This allows us to remove the atomic as we're now allocating both ids
in one go
- Use a shared header for vfs sample programs
- Fix build warnings for new sample program to list all mounts

Pull pid_max namespacing update from Christian Brauner:
"The pid_max sysctl is a global value. For a long time the default
value has been 65535 and during the pidfd dicussions Linus proposed to
bump pid_max by default. Based on this discussion systemd started
bumping pid_max to 2^22. So all new systems now run with a very high
pid_max limit with some distros having also backported that change.
The decision to bump pid_max is obviously correct. It just doesn't
make a lot of sense nowadays to enforce such a low pid number. There's
sufficient tooling to make selecting specific processes without typing
really large pid numbers available.
In any case, there are workloads that have expections about how large
pid numbers they accept. Either for historical reasons or
architectural reasons. One concreate example is the 32-bit version of
Android's bionic libc which requires pid numbers less than 65536.
There are workloads where it is run in a 32-bit container on a 64-bit
kernel. If the host has a pid_max value greater than 65535 the libc
will abort thread creation because of size assumptions of
pthread_mutex_t.
That's a fairly specific use-case however, in general specific
workloads that are moved into containers running on a host with a new
kernel and a new systemd can run into issues with large pid_max
values. Obviously making assumptions about the size of the allocated
pid is suboptimal but we have userspace that does it.
Of course, giving containers the ability to restrict the number of
processes in their respective pid namespace indepent of the global
limit through pid_max is something desirable in itself and comes in
handy in general.
Independent of motivating use-cases the existence of pid namespaces
makes this also a good semantical extension and there have been prior
proposals pushing in a similar direction. The trick here is to
minimize the risk of regressions which I think is doable. The fact
that pid namespaces are hierarchical will help us here.
What we mostly care about is that when the host sets a low pid_max
limit, say (crazy number) 100 that no descendant pid namespace can
allocate a higher pid number in its namespace. Since pid allocation is
hierarchial this can be ensured by checking each pid allocation
against the pid namespace's pid_max limit. This means if the
allocation in the descendant pid namespace succeeds, the ancestor pid
namespace can reject it. If the ancestor pid namespace has a higher
limit than the descendant pid namespace the descendant pid namespace
will reject the pid allocation. The ancestor pid namespace will
obviously not care about this.
All in all this means pid_max continues to enforce a system wide limit
on the number of processes but allows pid namespaces sufficient leeway
in handling workloads with assumptions about pid values and allows
containers to restrict the number of processes in a pid namespace
through the pid_max interface"

Pull pidfs updates from Christian Brauner:
- Rework inode number allocation
Recently we received a patchset that aims to enable file handle
encoding and decoding via name_to_handle_at(2) and
open_by_handle_at(2).
A crucical step in the patch series is how to go from inode number to
struct pid without leaking information into unprivileged contexts.
The issue is that in order to find a struct pid the pid number in the
initial pid namespace must be encoded into the file handle via
name_to_handle_at(2).
This can be used by containers using a separate pid namespace to
learn what the pid number of a given process in the initial pid
namespace is. While this is a weak information leak it could be used
in various exploits and in general is an ugly wart in the design.
To solve this problem a new way is needed to lookup a struct pid
based on the inode number allocated for that struct pid. The other
part is to remove the custom inode number allocation on 32bit systems
that is also an ugly wart that should go away.
Allocate unique identifiers for struct pid by simply incrementing a
64 bit counter and insert each struct pid into the rbtree so it can
be looked up to decode file handles avoiding to leak actual pids
across pid namespaces in file handles.
On both 64 bit and 32 bit the same 64 bit identifier is used to
lookup struct pid in the rbtree. On 64 bit the unique identifier for
struct pid simply becomes the inode number. Comparing two pidfds
continues to be as simple as comparing inode numbers.
On 32 bit the 64 bit number assigned to struct pid is split into two
32 bit numbers. The lower 32 bits are used as the inode number and
the upper 32 bits are used as the inode generation number. Whenever a
wraparound happens on 32 bit the 64 bit number will be incremented by
2 so inode numbering starts at 2 again.
When a wraparound happens on 32 bit multiple pidfds with the same
inode number are likely to exist. This isn't a problem since before
pidfs pidfds used the anonymous inode meaning all pidfds had the same
inode number. On 32 bit sserspace can thus reconstruct the 64 bit
identifier by retrieving both the inode number and the inode
generation number to compare, or use file handles. This gives the
same guarantees on both 32 bit and 64 bit.
- Implement file handle support
This is based on custom export operation methods which allows pidfs
to implement permission checking and opening of pidfs file handles
cleanly without hacking around in the core file handle code too much.
- Support bind-mounts
Allow bind-mounting pidfds. Similar to nsfs let's allow bind-mounts
for pidfds. This allows pidfds to be safely recovered and checked for
process recycling.
Instead of checking d_ops for both nsfs and pidfs we could in a
follow-up patch add a flag argument to struct dentry_operations that
functions similar to file_operations->fop_flags.

Add both asm-based and C-based tests which have 'may_goto 0' insns.
For the following code in C-based test,
int i, tmp[3];
for (i = 0; i < 3 && can_loop; i++)
tmp[i] = 0;
The clang compiler (clang 19 and 20) generates
may_goto 2
may_goto 1
may_goto 0
r1 = 0
r2 = 0
r3 = 0
The above asm codes are due to llvm pass SROAPass. This ensures the
successful verification since tmp[0-2] are initialized. Otherwise,
the code without SROAPass like
may_goto 5
r1 = 0
may_goto 3
r2 = 0
may_goto 1
r3 = 0
will have verification failure.
Although from the source code C-based test should have verification
failure, clang compiler optimization generates code with successful
verification. If gcc generates different asm codes than clang, the
following code can be used for gcc:
int i, tmp[3];
for (i = 0; i < 3; i++)
tmp[i] = 0;

"Features:
- Support caching symlink lengths in inodes
The size is stored in a new union utilizing the same space as
i_devices, thus avoiding growing the struct or taking up any more
space
When utilized it dodges strlen() in vfs_readlink(), giving about
1.5% speed up when issuing readlink on /initrd.img on ext4
- Add RWF_DONTCACHE iocb and FOP_DONTCACHE file_operations flag
If a file system supports uncached buffered IO, it may set
FOP_DONTCACHE and enable support for RWF_DONTCACHE.
If RWF_DONTCACHE is attempted without the file system supporting
it, it'll get errored with -EOPNOTSUPP
- Enable VBOXGUEST and VBOXSF_FS on ARM64
Now that VirtualBox is able to run as a host on arm64 (e.g. the
Apple M3 processors) we can enable VBOXSF_FS (and in turn
VBOXGUEST) for this architecture.
Tested with various runs of bonnie++ and dbench on an Apple MacBook

The main purpose of the test is to demonstrate the lock problem for the
free of bpf_timer under PREEMPT_RT. When freeing a bpf_timer which is
running on other CPU in bpf_timer_cancel_and_free(), hrtimer_cancel()
will try to acquire a spin-lock (namely softirq_expiry_lock), however
the freeing procedure has already held a raw-spin-lock.
The test first creates two threads: one to start timers and the other to
free timers. The start-timers thread will start the timer and then wake
up the free-timers thread to free these timers when the starts complete.
After freeing, the free-timer thread will wake up the start-timer thread
to complete the current iteration. A loop of 10 iterations is used.

Particularly tricky are spills both smaller or larger than key size. For
smaller, we need to ensure verifier doesn't let through a potential read
into unchecked bytes. For larger, endianness comes into play, as the
native endian value tracked in the verifier may not be the bytes the
kernel would have read out of the key pointer. So check that we disallow
both.

This commit allows progs to elide a null check on statically known map
lookup keys. In other words, if the verifier can statically prove that
the lookup will be in-bounds, allow the prog to drop the null check.
This is useful for two reasons:
1. Large numbers of nullness checks (especially when they cannot fail)
unnecessarily pushes prog towards BPF_COMPLEXITY_LIMIT_JMP_SEQ.
2. It forms a tighter contract between programmer and verifier.
For (1), bpftrace is starting to make heavier use of percpu scratch
maps. As a result, for user scripts with large number of unrolled loops,
we are starting to hit jump complexity verification errors. These
percpu lookups cannot fail anyways, as we only use static key values.
Eliding nullness probably results in less work for verifier as well.
For (2), percpu scratch maps are often used as a larger stack, as the
currrent stack is limited to 512 bytes. In these situations, it is
desirable for the programmer to express: "this lookup should never fail,
and if it does, it means I messed up the code". By omitting the null
check, the programmer can "ask" the verifier to double check the logic.
Tests also have to be updated in sync with these changes, as the
verifier is more efficient with this change. Notable, iters.c tests had
to be changed to use a map type that still requires null checks, as it's
exercising verifier tracking logic w.r.t iterators.

Previously, the verifier was treating all PTR_TO_STACK registers passed
to a helper call as potentially written to by the helper. However, all
calls to check_stack_range_initialized() already have precise access type
information available.
Rather than treat ACCESS_HELPER as a proxy for BPF_WRITE, pass
enum bpf_access_type to check_stack_range_initialized() to more
precisely track helper arguments.
One benefit from this precision is that registers tracked as valid
spills and passed as a read-only helper argument remain tracked after
the call. Rather than being marked STACK_MISC afterwards.
An additional benefit is the verifier logs are also more precise. For
this particular error, users will enjoy a slightly clearer message. See
included selftest updates for examples.

The tool pp_alloc_fail.py tested error recovery by injecting errors
into the function page_pool_alloc_pages(). The page pool allocation
function page_pool_dev_alloc() does not end up calling
page_pool_alloc_pages(). page_pool_alloc_netmems() seems to be the
function that is called by all of the page pool alloc functions in
the API, so move error injection to that function instead.

When redirecting the split BTF to the vmlinux base BTF, we need to mark
the distilled base struct/union members of split BTF structs/unions in
id_map with BTF_IS_EMBEDDED. This indicates that these types must match
both name and size later. So if a needed composite type, which is the
member of composite type in the split BTF, has a different size in the
base BTF we wish to relocate with, btf__relocate() should error out.

libbpf automatically adjusts autoload for struct_ops programs,
see libbpf.c:bpf_object_adjust_struct_ops_autoload.
For example, if there is a map:
SEC(".struct_ops.link")
struct sched_ext_ops ops = {
.enqueue = foo,
.tick = bar,
};
Both 'foo' and 'bar' would be loaded if 'ops' autocreate is true,
both 'foo' and 'bar' would be skipped if 'ops' autocreate is false.
This means that when veristat processes object file with 'ops',
it would load 4 programs in total: two programs per each
'process_prog' call.
The adjustment occurs at object load time, and libbpf remembers
association between 'ops' and 'foo'/'bar' at object open time.
The only way to persuade libbpf to load one of two is to adjust map
initial value, such that only one program is referenced.
This patch does exactly that, significantly reducing time to process
object files with big number of struct_ops programs.

- Print the rc errors at the end of the line.
- Print the MIB counters.
- Use the same ss options: add -M (MPTCP sockets) and -e (detailed

While at it, also print of the 'max' time only in case of success,
because 'mptcp_connect.c' will already print this info in case of error,

When porting librseq commit:
commit c7b45750fa85 ("Adapt to glibc __rseq_size feature detection")
from librseq to the kernel selftests, the following line was missed
at the end of rseq_init():
rseq_size = get_rseq_kernel_feature_size();
which effectively leaves rseq_size initialized to -1U when glibc does not
have rseq support. glibc supports rseq from version 2.35 onwards.
In a following librseq commit
commit c67d198627c2 ("Only set 'rseq_size' on first thread registration")
to mimic the libc behavior, a new approach is taken: don't set the
feature size in 'rseq_size' until at least one thread has successfully
registered. This allows using 'rseq_size' in fast-paths to test for both
registration status and available features. The caveat is that on libc
either all threads are registered or none are, while with bare librseq
it is the responsability of the user to register all threads using rseq.
This combines the changes from the following librseq git commits:
commit c7b45750fa85 ("Adapt to glibc __rseq_size feature detection")
commit c67d198627c2 ("Only set 'rseq_size' on first thread registration")

Resctrl selftest prints a message on test failure that Sub-Numa
Clustering (SNC) could be enabled and points the user to check their BIOS
settings. No actual check is performed before printing that message so
it is not very accurate in pinpointing a problem.
When there is SNC support for kernel's resctrl subsystem and SNC is
enabled then sub node files are created for each node in the resctrlfs.
The sub node files exist in each regular node's L3 monitoring directory.
The reliable path to check for existence of sub node files is
/sys/fs/resctrl/mon_data/mon_L3_00/mon_sub_L3_00.
Add helper that checks for mon_sub_L3_00 existence.

Sub-NUMA Cluster divides CPUs sharing an L3 cache into separate NUMA
nodes. Systems may support splitting into either two, three, four or six
nodes. When SNC mode is enabled the effective amount of L3 cache
available for allocation is divided by the number of nodes per L3.
It's possible to detect which SNC mode is active by comparing the number
of CPUs that share a cache with CPU0, with the number of CPUs on node0.
Detect SNC mode once and let other tests inherit that information.
Update CFLAGS after including lib.mk in the Makefile so that fallthrough
macro can be used.
To check if SNC detection is reliable one can check the
/sys/devices/system/cpu/offline file. If it's empty, it means all cores
are operational and the ratio should be calculated correctly. If it has
any contents, it means the detected SNC mode can't be trusted and should
be disabled.
Check if detection was not reliable due to offline cpus. If it was skip
running tests since the results couldn't be trusted.

intptr_t and uintptr_t are not big enough types on 32-bit architectures

Replace intptr_t and uintptr_t with intmax_t and uintmax_t, respectively.

The root cause is actually in the user-space bits: the test program
currently disconnects as soon as all the pending data has been spooled,
generating an FASTCLOSE. If such option reaches the peer before the
latter has reached the closed status, the msk socket will report an
error to the user-space, as per protocol specification, causing the
above failure.
Address the issue explicitly waiting for all the relevant sockets to

PKEY_ALLOW_ALL is meant to represent the pkey register value that allows
all accesses (enables all pkeys). However its current naming suggests
that the value applies to *one* key only (like PKEY_DISABLE_ACCESS for
instance).
Rename PKEY_ALLOW_ALL to PKEY_REG_ALLOW_ALL to avoid such
misunderstanding. This is consistent with the PKEY_REG_ALLOW_NONE macro
introduced by commit 6e182dc9f2 ("selftests/mm: Use generic pkey
register manipulation").

sys_pkey_alloc, sys_pkey_free and sys_mprotect_pkey are currently used in
protections_keys.c, while pkey_sighandler_tests.c calls the libc wrappers
directly (e.g. pkey_mprotect()). This is probably ok when using glibc
(those symbols appeared a while ago), but Musl does not currently provide
them. The logging in the helpers from pkey-helpers.h can also come in
handy.
Make things more consistent by using the sys_pkey helpers in
pkey_sighandler_tests.c too. To that end their implementation is moved to
a common .c file (pkey_util.c). This also enables calling
is_pkeys_supported() outside of protections_keys.c, since it relies on
sys_pkey_{alloc,free}.

The pkey tests define a whole lot of functions and some global variables.
A few are truly global (declared in pkey-helpers.h), but the majority are
file-scoped. Make sure those are labelled static.
Some of the pkey_{access,write}_{allow,deny} helpers are not called, or
only called when building for some architectures. Mark them
__maybe_unused to suppress compiler warnings.

Some of the functions declared in pkey-helpers.h are actually defined in
protections_keys.c, meaning they can only be called from
protections_keys.c. This is less than ideal, but it is hard to avoid as
these helpers are themselves called from inline functions in
pkey-<arch>.h. Let's at least add a comment clarifying that. We can also
remove the empty definition in pkey_sighandler_tests.c:
expected_pkey_fault() is not meant to be called from there.

Headers should not define non-inline functions, as this prevents them from
being included more than once in a given program. pkey-helpers.h and the
arch-specific headers it includes currently define multiple such
non-inline functions.
In most cases those functions can simply be made inline - this patch does
just that. read_ptr() is an exception as it must not be inlined. Since
it is only called from protection_keys.c, we just move it there.
