lib: util_macros_kunit: add kunit test for util_macros.h

A bug was found in the find_closest() (find_closest_descending() is also
affected after some testing), where for certain values with small
progressions of 1, 2 & 3, the rounding (done by averaging 2 values) causes
an incorrect index to be returned.

The bug is described in more detail in the commit which fixes the bug.
This commit adds a kunit test to validate that the fix works correctly.

This kunit test adds some of the arrays (from the driver-sphere) that seem
to produce issues with the 'find_closest()' macro. Specifically the one
from ad7606 driver (with which the bug was found) and from the ina2xx
drivers, which shows the quirk with 'find_closest()' with elements in a
array that have an interval of 3.

For the find_closest_descending() tests, the same arrays are used as for
the find_closest(), but in reverse; the idea is that
'find_closest_descending()' should return the sames indices as
'find_closest()' but in reverse.

For testing both macros, there are 4 special arrays created, one for
testing find_closest{_descending}() for arrays of progressions 1, 2, 3 and
4. The idea is to show that (for progressions of 1, 2 & 3) the fix works
as expected. When removing the fix, the issues should start to show up.

Then an extra array of negative and positive values is added. There are
currently no such arrays within drivers, but one could expect that these
macros behave correctly even for such arrays.

To run this kunit:
./tools/testing/kunit/kunit.py run "*util_macros*"

lib/min_heap: introduce non-inline versions of min heap API functions

Patch series "Enhance min heap API with non-inline functions and
optimizations", v2.

Add non-inline versions of the min heap API functions in lib/min_heap.c
and updates all users outside of kernel/events/core.c to use these
non-inline versions. To mitigate the performance impact of indirect
function calls caused by the non-inline versions of the swap and compare
functions, a builtin swap has been introduced that swaps elements based on
their size. Additionally, it micro-optimizes the efficiency of the min
heap by pre-scaling the counter, following the same approach as in
lib/sort.c. Documentation for the min heap API has also been added to the
core-api section.


This patch (of 10):

All current min heap API functions are marked with '__always_inline'.
However, as the number of users increases, inlining these functions
everywhere leads to a increase in kernel size.

In performance-critical paths, such as when perf events are enabled and
min heap functions are called on every context switch, it is important to
retain the inline versions for optimal performance. To balance this, the
original inline functions are kept, and additional non-inline versions of
the functions have been added in lib/min_heap.c.

Merge tag 'net-next-6.13' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Paolo Abeni:
"The most significant set of changes is the per netns RTNL. The new
behavior is disabled by default, regression risk should be contained.

Notably the new config knob PTP_1588_CLOCK_VMCLOCK will inherit its
default value from PTP_1588_CLOCK_KVM, as the first is intended to be
a more reliable replacement for the latter.

Core:

- Started a very large, in-progress, effort to make the RTNL lock
scope per network-namespace, thus reducing the lock contention
significantly in the containerized use-case, comprising:
- RCU-ified some relevant slices of the FIB control path
- introduce basic per netns locking helpers
- namespacified the IPv4 address hash table
- remove rtnl_register{,_module}() in favour of
rtnl_register_many()
- refactor rtnl_{new,del,set}link() moving as much validation as
possible out of RTNL lock
- convert all phonet doit() and dumpit() handlers to RCU
- convert IPv4 addresses manipulation to per-netns RTNL
- convert virtual interface creation to per-netns RTNL
the per-netns lock infrastructure is guarded by the
CONFIG_DEBUG_NET_SMALL_RTNL knob, disabled by default ad interim.

- Introduce NAPI suspension, to efficiently switching between busy
polling (NAPI processing suspended) and normal processing.

- Migrate the IPv4 routing input, output and control path from direct
ToS usage to DSCP macros. This is a work in progress to make ECN
handling consistent and reliable.

- Add drop reasons support to the IPv4 rotue input path, allowing
better introspection in case of packets drop.

- Make FIB seqnum lockless, dropping RTNL protection for read access.

- Make inet{,v6} addresses hashing less predicable.

- Allow providing timestamp OPT_ID via cmsg, to correlate TX packets
and timestamps

Things we sprinkled into general kernel code:

- Add small file operations for debugfs, to reduce the struct ops
size.

- Refactoring and optimization for the implementation of page_frag
API, This is a preparatory work to consolidate the page_frag
implementation.

Netfilter:

- Optimize set element transactions to reduce memory consumption

- Extended netlink error reporting for attribute parser failure.

- Make legacy xtables configs user selectable, giving users the
option to configure iptables without enabling any other config.

- Address a lot of false-positive RCU issues, pointed by recent CI
improvements.

BPF:

- Put xsk sockets on a struct diet and add various cleanups. Overall,
this helps to bump performance by 12% for some workloads.

- Extend BPF selftests to increase coverage of XDP features in
combination with BPF cpumap.

- Optimize and homogenize bpf_csum_diff helper for all archs and also
add a batch of new BPF selftests for it.

- Extend netkit with an option to delegate skb->{mark,priority}
scrubbing to its BPF program.

- Make the bpf_get_netns_cookie() helper available also to tc(x) BPF
programs.

Protocols:

- Introduces 4-tuple hash for connected udp sockets, speeding-up
significantly connected sockets lookup.

- Add a fastpath for some TCP timers that usually expires after
close, the socket lock contention.

- Add inbound and outbound xfrm state caches to speed up state
lookups.

- Avoid sending MPTCP advertisements on stale subflows, reducing
risks on loosing them.

- Make neighbours table flushing more scalable, maintaining per
device neigh lists.

Driver API:

- Introduce a unified interface to configure transmission H/W
shaping, and expose it to user-space via generic-netlink.

- Add support for per-NAPI config via netlink. This makes napi
configuration persistent across queues removal and re-creation.
Requires driver updates, currently supported drivers are:
nVidia/Mellanox mlx4 and mlx5, Broadcom brcm and Intel ice.

- Add ethtool support for writing SFP / PHY firmware blocks.

- Track RSS context allocation from ethtool core.

- Implement support for mirroring to DSA CPU port, via TC mirror
offload.

- Consolidate FDB updates notification, to avoid duplicates on
device-specific entries.

- Expose DPLL clock quality level to the user-space.

- Support master-slave PHY config via device tree.

Tests and tooling:

- forwarding: introduce deferred commands, to simplify the cleanup
phase

Drivers:

- Updated several drivers - Amazon vNic, Google vNic, Microsoft vNic,
Intel e1000e and Broadcom Tigon3 - to use netdev-genl to link the
IRQs and queues to NAPI IDs, allowing busy polling and better
introspection.

- Ethernet high-speed NICs:

- mlx5:
- a large refactor to implement support for cross E-Switch
scheduling

Merge branch 'packing-various-improvements-and-kunit-tests'

Jacob Keller says:

====================
packing: various improvements and KUnit tests

This series contains a handful of improvements and fixes for the packing
library, including the addition of KUnit tests.

There are two major changes which might be considered bug fixes:

1) The library is updated to handle arbitrary buffer lengths, fixing
undefined behavior when operating on buffers which are not a multiple
of 4 bytes.

2) The behavior of QUIRK_MSB_ON_THE_RIGHT is fixed to match the intended
behavior when operating on packings that are not byte aligned.

These are not sent to net because no driver currently depends on this
behavior. For (1), the existing users of the packing API all operate on
buffers which are multiples of 4-bytes. For (2), no driver currently uses
QUIRK_MSB_ON_THE_RIGHT. The incorrect behavior was found while writing
KUnit tests.

This series also includes a handful of minor cleanups from Vladimir, as
well as a change to introduce a separated pack() and unpack() API. This API
is not (yet) used by a driver, but is the first step in implementing
pack_fields() and unpack_fields() which will be used in future changes for
the ice driver and changes Vladimir has in progress for other drivers using
the packing API.

This series is part 1 of a 2-part series for implementing use of
lib/packing in the ice driver. The 2nd part includes a new pack_fields()
and unpack_fields() implementation inspired by the ice driver's existing
bit packing code. It is built on top of the split pack() and unpack()
code. Additionally, the KUnit tests are built on top of pack() and
unpack(), based on original selftests written by Vladimir.

Fitting the entire library changes and drivers changes into a single series
exceeded the usual series limits.

Add 24 simple KUnit tests for the lib/packing.c pack() and unpack() APIs.

The first 16 tests exercise all combinations of quirks with a simple magic
number value on a 16-byte buffer. The remaining 8 tests cover
non-multiple-of-4 buffer sizes.

These tests were originally written by Vladimir as simple selftest
functions. I adapted them to KUnit, refactoring them into a table driven
approach. This will aid in adding additional tests in the future.

New implementation for IO memcpy and IO memset

The IO memcpy and IO memset functions in asm-generic/io.h simply call
memcpy and memset. This can lead to alignment problems or faults on
architectures that do not define their own version and fall back to
these defaults.
This patch introduces new implementations for IO memcpy and IO memset,
that use read{l,q} accessor functions, align accesses to machine word
size, and resort to byte accesses when the target memory is not aligned.
For new architectures and existing ones that were using the old
fallbacks these functions are save to use, because IO memory constraints
are taken into account. Moreover, architectures with similar
implementations can now use these new versions, not needing to implement
their own.

Merge tag 'mm-nonmm-stable-2024-09-21-07-52' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Pull non-MM updates from Andrew Morton:
"Many singleton patches - please see the various changelogs for
details.

Quite a lot of nilfs2 work this time around.

Notable patch series in this pull request are:

- "mul_u64_u64_div_u64: new implementation" by Nicolas Pitre, with
assistance from Uwe Kleine-König. Reimplement mul_u64_u64_div_u64()
to provide (much) more accurate results. The current implementation
was causing Uwe some issues in the PWM drivers.

- "xz: Updates to license, filters, and compression options" from
Lasse Collin. Miscellaneous maintenance and kinor feature work to
the xz decompressor.

- "Fix some GDB command error and add some GDB commands" from
Kuan-Ying Lee. Fixes and enhancements to the gdb scripts.

- "treewide: add missing MODULE_DESCRIPTION() macros" from Jeff
Johnson. Adds lots of MODULE_DESCRIPTIONs, thus fixing lots of
warnings about this.

- "nilfs2: add support for some common ioctls" from Ryusuke Konishi.
Adds various commonly-available ioctls to nilfs2.

- "This series fixes a number of formatting issues in kernel doc
comments" from Ryusuke Konishi does that.

- "nilfs2: prevent unexpected ENOENT propagation" from Ryusuke
Konishi. Fix issues where -ENOENT was being unintentionally and
inappropriately returned to userspace.

- "nilfs2: assorted cleanups" from Huang Xiaojia.

- "nilfs2: fix potential issues with empty b-tree nodes" from Ryusuke
Konishi fixes some issues which can occur on corrupted nilfs2
filesystems.

- "scripts/decode_stacktrace.sh: improve error reporting and
usability" from Luca Ceresoli does those things"
