Add a "--multi <do-op> <json>" command line to ynl that makes it
possible to add several operations to a single netlink request payload.
The --multi command line option is repeated for each operation.
This is used by the nftables family for transaction batches. For
example:
./tools/net/ynl/cli.py \
--spec Documentation/netlink/specs/nftables.yaml \
--multi batch-begin '{"res-id": 10}' \
--multi newtable '{"name": "test", "nfgen-family": 1}' \
--multi newchain '{"name": "chain", "table": "test", "nfgen-family": 1}' \
--multi batch-end '{"res-id": 10}'
[None, None, None, None]
It can also be used for bundling get requests:
./tools/net/ynl/cli.py \
--spec Documentation/netlink/specs/nftables.yaml \
--multi gettable '{"name": "test", "nfgen-family": 1}' \
--multi getchain '{"name": "chain", "table": "test", "nfgen-family": 1}' \
--output-json
[{"name": "test", "use": 1, "handle": 1, "flags": [],
"nfgen-family": 1, "version": 0, "res-id": 2},
{"table": "test", "name": "chain", "handle": 1, "use": 0,
"nfgen-family": 1, "version": 0, "res-id": 2}]

This addresses this perf tools build warning:
diff -u tools/perf/trace/beauty/include/uapi/linux/vhost.h include/uapi/linux/vhost.h
But this specific process, usually boring, this time around catch a
problem, namely the addition of VDPA_GET_VRING_SIZE used an ioctl number
already taken, which went on unnoticed and only got caught when the
tools/perf/trace/beauty/vhost_virtio_ioctl.sh script was run as part of
the perf tools process of updating the tools copies of system headers it
uses for creating id->string tables that, well, broke the perf tools
build because there were multiple initializations in the strings table
for the 0x80 entry...
I'm adding here a link to the discussion, that is lacking in the fix for
the reported problem, and a quote from one of the developers involved:
"Thanks a lot for taking care of this! So given the header is actually
buggy pls hang on to this change until I merge the fix for the header
(you were CC'd on the patch). It's great we have this redundancy which
allowed us to catch the bug in time, and many thanks to Namhyung Kim for
reporting the issue!"
This is here as a hint for anyone thinking about ways to automate
checking these issues in a more automated way... ;-)

Turbostat assumed that every package had a die_id = 0.

If sysfs directory "intel_uncore_frequency/cluster00/" exists,
then use uncore cluster code (now its own routine).
The previous check for
"intel_uncore_frequency/package_00_die_00/current_freq_khz",
could be unreliable in the face of sparse die id's.

Kernel developers often need to diagnose remote customer systems
with the latest turbostat, yet customers are running binary distros
with out-dated turbostat and the customer has no experience
cloning linux kernel trees.
Add a turbostat "snapshot" makefile target to create a standalone
source snapshot from the developer's git tree, appropriately hacked
so that the customer can build turbostat without a kernel tree.
Include the turbostat binary in the snapshot, for convenience in
those situations where the source and destination are trusted,
(and have new enough glibc to execute).
The snapshot is named with the date it was taken rather than
the turbostat VERSION, as it could occur between VERSIONS...

Add a tool to generate a picture of the current DAPM state for a sound
card.
dapm-graph is inspired by vizdapm which used to be published on a Wolfson
Micro git repository now disappeared, and has a few forks around:
https://github.com/mihais/asoc-tools
https://github.com/alexandrebelloni/asoc-tools
dapm-graph is a full reimplementation with several improvements while still
being a self-contained shell script:
Improvements to rendered output:
- shows the entire card, not one component hierarchy only
- each component is rendered in a separate box
- shows widget on/off status based on widget information alone (the
original vizdapm propagates the "on" green colour to the first input
widget)
- use bold line and gray background and not only green/red line to show
on/off status (for the color blind)
Improvements for embedded system developers:
- remote mode: get state of remote device (possibly with minimal rootfs)
via SSH, but parsing locally for faster operation
- compatible with BusyBox shell, not only bash
Usability improvements:
- flexible command line (uses getopts for parsing)
- detailed help text
- flag to enable detailed debug logging
- graphviz output format detected from file extension, not hard coded
- a self-contained shell script
Usage is designed to be simple:
dapm-grpah -c CARD - get state from debugfs for CARD
dapm-grpah -c CARD -r REMOTE_TARGET - same, but remotely via SSH
dapm-grpah -d STATE_DIR - from a local copy of the debugfs
tree for a card

Pull kvm fixes from Paolo Bonzini:
"This is a bit on the large side, mostly due to two changes:
- Changes to disable some broken PMU virtualization (see below for
details under "x86 PMU")
- Clean up SVM's enter/exit assembly code so that it can be compiled
without OBJECT_FILES_NON_STANDARD. This fixes a warning "Unpatched
return thunk in use. This should not happen!" when running KVM
selftests.
Everything else is small bugfixes and selftest changes:
- Fix a mostly benign bug in the gfn_to_pfn_cache infrastructure
where KVM would allow userspace to refresh the cache with a bogus
GPA. The bug has existed for quite some time, but was exposed by a
new sanity check added in 6.9 (to ensure a cache is either
GPA-based or HVA-based).
- Drop an unused param from gfn_to_pfn_cache_invalidate_start() that
got left behind during a 6.9 cleanup.
- Fix a math goof in x86's hugepage logic for
KVM_SET_MEMORY_ATTRIBUTES that results in an array overflow
(detected by KASAN).
- Fix a bug where KVM incorrectly clears root_role.direct when
userspace sets guest CPUID.
- Fix a dirty logging bug in the where KVM fails to write-protect
SPTEs used by a nested guest, if KVM is using Page-Modification
Logging and the nested hypervisor is NOT using EPT.
x86 PMU:
- Drop support for virtualizing adaptive PEBS, as KVM's
implementation is architecturally broken without an obvious/easy
path forward, and because exposing adaptive PEBS can leak host LBRs
to the guest, i.e. can leak host kernel addresses to the guest.
- Set the enable bits for general purpose counters in
PERF_GLOBAL_CTRL at RESET time, as done by both Intel and AMD
processors.
- Disable LBR virtualization on CPUs that don't support LBR
callstacks, as KVM unconditionally uses
PERF_SAMPLE_BRANCH_CALL_STACK when creating the perf event, and
would fail on such CPUs.
Tests:
- Fix a flaw in the max_guest_memory selftest that results in it
exhausting the supply of ucall structures when run with more than
256 vCPUs.
- Mark KVM_MEM_READONLY as supported for RISC-V in
set_memory_region_test"

This is a common failure mode when probing userspace C++ code (where the
mangling adds significant length to the symbol names).
Prior to this patch, only a very generic error message is produced,
making the user guess at what the issue is.

In several places we had
char buf[64];
...
snprintf(buf, 64, ...);
This patch changes it to
char buf[64];
...
snprintf(buf, sizeof(buf), ...);
so the "64" is only stated once.

These tests record in a mode that includes kernel trace but look for
samples of a userspace process. This makes them sensitive to any kernel
compilation options that increase the amount of time spent in the
kernel. If the trace buffer is completely filled before userspace is
reached then the test will fail. Double the buffer size to fix this.
The other tests in the same file aren't sensitive to this for various
reasons, for example the iterate devices test filters by userspace trace
only. But in order to keep coverage of all the modes, increase the
buffer size rather than filtering by userspace for the basic tests.

Test cases need to exit with non-zero status if they failed,
we currently don't do that:
# KTAP version 1
# 1..3
# # At /root/ksft-net-drv/drivers/net/./ping.py line 18:
# # Check failed 1 != 2
# not ok 1 ping.test_v4
# ok 2 ping.test_v6
# ok 3 ping.test_tcp
# # Totals: pass:2 fail:1 xfail:0 xpass:0 skip:0 error:0
ok 1 selftests: drivers/net: ping.py
^^^^
It's a bit tempting to make the exit part of ksft_run(),
but that only works well for very trivial setups. We can
revisit this later, if people forget to call ksft_exit().

Totals currently only pay attention to exceptions, if check fails
(say ksft_eq()) the test case will be counted as pass:
# At /ksft/drivers/net/./ping.py line 18:
# Check failed 1 != 2
not ok 1 ping.test_v4
ok 2 ping.test_v6
ok 3 ping.test_tcp
# Totals: pass:3 fail:0 xfail:0 xpass:0 skip:0 error:0
^^^^^^^^^^^^^
Pay attention to the result.

Apparently it's more legal to pass the format as NULL, than
it is to use an empty string. Clang complains about empty
formats:

Character sequences starting with `\` are interpreted by python as
escaped Unicode characters. However, they have other meaning in
regular expressions (e.g: "\d").
It seems Python >= 3.12 starts emitting a SyntaxWarning when these
escaped sequences are not recognized as valid Unicode characters.
An example of these warnings:
tools/testing/selftests/net/openvswitch/ovs-dpctl.py:505:
SyntaxWarning: invalid escape sequence '\d'
Fix all the warnings by flagging literals as raw strings.

selftest build is fairly noisy, it's easy to miss warnings.
It's standard practice to add alternative messages in
the Makefile. I was grepping for existing solutions,
and found that bpf already has the right knobs.
Move them to lib.mk and adopt in net.
Convert the basic rules in lib.mk.

Test "perf probe of function from different CU" fails due to certain
configs not being enabled. Building the kernel with
CONFIG_KPROBE_EVENTS=y and CONFIG_UPROBE_EVENTS=y fixes the issue. As
CONFIG_KPROBE_EVENTS is dependent on CONFIG_KPROBES, enable it as well.
Some platforms enable these configs as a part of their defconfig, so
this change is only required for the ones that don't do so.
