xdp_cpumap_attach, in its current form, only checks that an xdp cpumap
program can be executed, but not that it performs correctly the cpu
redirect as configured by userspace (bpf_prog_test_run_opts will return
success even if the redirect program returns an error)
Add a check to ensure that the program performs the configured redirect
as well. The check is based on a global variable incremented by a
chained program executed only if the redirect program properly executes.

xdp_redir_prog currently redirects packets based on the entry at index 1
in cpu_map, but the corresponding test only manipulates the entry at
index 0. This does not really affect the test in its current form since
the program is detached before having the opportunity to execute, but it
needs to be fixed before being able improve the corresponding test (ie,
not only test attach/detach but also the redirect feature)
Fix this XDP program by making it redirect packets based on entry 0 in
cpu_map instead of entry 1.

The hmm2 double_map test was failing due to an incorrect buffer->mirror
size. The buffer->mirror size was 6, while buffer->ptr size was 6 *
PAGE_SIZE. The test failed because the kernel's copy_to_user function was
attempting to copy a 6 * PAGE_SIZE buffer to buffer->mirror. Since the
size of buffer->mirror was incorrect, copy_to_user failed.
This patch corrects the buffer->mirror size to 6 * PAGE_SIZE.

The RED test uses a pair of TBF shapers. The first to get predictably-sized
stream of traffic, and second to get a 100% saturated chokepoint. To this
chokepoint it injects individual packets. Because the chokepoint is
saturated, these additional packets go straight to the backlog. This allows
the test to check RED behavior across various queue sizes.
The shapers are rated at 1Gbps, for historical reasons (before mlxsw
supported TBF offload, the test used port speed to create the chokepoints).
Machines with a low-power CPU may have trouble consistently generating
1Gbps of traffic, and the test then spuriously fails.
Instead, drop the rate to 200Mbps (Spectrum has a guaranteed shaper rate
granularity of 200Mbps, so anything lower is not guaranteed to work well).
Because that means fewer packets will be mirrored in the ECN-mark test,
adjust the passing condition accordingly.

This test works by injecting into a port with a maxed-out queue a couple
packets and checks if a corresponding number of packets were dropped. This
has worked well on Spectrum<4, but on Spectrum-4 it has been noisy. This
is in line with the observation that on Spectrum-4, queue size tends to
fluctuate more. A handful of packets could then still be accepted to the
queue even though it was nominally full just recently.
In order to accommodate this behavior, send many more packets. The buffer
can fit N extra packets, but not N% packets. This therefore allows us to
set wider absolute margins, while actually narrowing them relatively.

The qdisc stats are taken from the port's periodic HW stats, which are
updated once a second. We try to accommodate the latency by using busywait
in build_backlog().
The issue in that seems to be that when do_mark_test() builds the backlog,
it makes the decision whether to send more packets based on the first
instance of the queue depth stat exceeding the current value, when in fact
more traffic is on the way and the queue depth would increase further. This
leads to failures in TC 1 of mark-mirror test, where we see the following
failure:
TEST: TC 0: marked packets mirror'd [ OK ]
TEST: TC 1: marked packets mirror'd [FAIL]
Spurious packets (1680 -> 2290) observed without buffer pressure
Fix by waiting for the full second before reading the queue depth for the
first time, to make sure it reflects all in-flight traffic.

Backlog fluctuates on Spectrum-4 much more than on <4. In practice we can
sample queue depth values going from about -12% to about +7% of the
configured RED limit. The test which checks the queue size has a limit of
+-10%, and as a result often fails. We attempted to fix the issue by
busywaiting for several seconds hoping to get within the bounds, but that
still proved to be too noisy (or the wait time would be impractically
long). Unfortunately we have to bump the value tolerance from 10% to 15%,
which in this patch do.

Merge tag 'kvmarm-fixes-6.12-1' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD
KVM/arm64 fixes for 6.12, take #1
- Fix pKVM error path on init, making sure we do not change critical
system registers as we're about to fail
- Make sure that the host's vector length is at capped by a value
common to all CPUs
- Fix kvm_has_feat*() handling of "negative" features, as the current
code is pretty broken
- Promote Joey to the status of official reviewer, while James steps
down -- hopefully only temporarly
This kselftest fixes update for Linux 6.12-rc2 consists of fixes
to build warnings, install scripts, run-time error path, and
git status cleanups to tests:
-- devices/probe: fix for Python3 regex string syntax warnings
-- clone3: removing unused macro from clone3_cap_checkpoint_restore()
-- vDSO: fix to align getrandom states to cache line
-- core and exec: add missing executables to .gitignore files
-- rtc: change to skip test if /dev/rtc0 can't be accessed
-- timers/posix: fix warn_unused_result result in __fatal_error()
-- breakpoints: fix to detect suspend successful condition correctly
-- hid: fix to install required dependencies to run the test

MONOTONIC{,_RAW} timestamps for PTP_SYS_OFFSET_EXTENDED") clock_gettime()
now allows retrieval of pre/post timestamps for CLOCK_MONOTONIC and
CLOCK_MONOTONIC_RAW timebases along with the previously supported
CLOCK_REALTIME.
This patch adds a command line option 'y' to the testptp program to
choose one of the allowed timebases [realtime aka system, monotonic,

Currently, the second bridge command overwrites the first one.
Fix this by adding this VID to the interface behind $swp2.
The one_bridge_two_pvids() test intends to check that there is no
leakage of traffic between bridge ports which have a single VLAN - the
PVID VLAN.
Because of a typo, port $swp1 is configured with a PVID twice (second
command overwrites first), and $swp2 isn't configured at all (and since
the bridge vlan_default_pvid property is set to 0, this port will not
have a PVID at all, so it will drop all untagged and priority-tagged
traffic).
So, instead of testing the configuration that was intended, we are
testing a different one, where one port has PVID 2 and the other has
no PVID. This incorrect version of the test should also pass, but is
ineffective for its purpose, so fix the typo.
This typo has an impact on results of the test,
potentially leading to wrong conclusions regarding
the functionality of a network device.
The tests results:
TEST: Switch ports in VLAN-aware bridge with different PVIDs:
Unicast non-IP untagged [ OK ]
Multicast non-IP untagged [ OK ]
Broadcast non-IP untagged [ OK ]
Unicast IPv4 untagged [ OK ]

Slightly high amount of changes in this round, partly because of my
vacation in the last weeks. But all changes are small and nothing
looks worrisome.
The biggest LOCs is MAINTAINERS updates, and there is a core change
for card-ID string creation for non-ASCII inputs. Others are rather
device-specific, such as new quirks and device IDs for ASoC, usual
HD-audio and USB-audio quirks and fixes, as well as regression fixes
in HD-audio HDMI audio and Conexant codec.

The test runs "devlink reload" explicitly. Instead, it is better to use
devlink_reload() which waits for udev events to be processed. Do not sleep
after reload, as devlink_reload() blocks until all the netdevs are renamed.

step_after_suspend_test fails with device busy error while
writing to /sys/power/state to start suspend. The test believes
it failed to enter suspend state with
$ sudo ./step_after_suspend_test
TAP version 13
Bail out! Failed to enter Suspend state
However, in the kernel message, I indeed see the system get
suspended and then wake up later.

After investigation, I noticed that for the code block
if (write(power_state_fd, "mem", strlen("mem")) != strlen("mem"))
ksft_exit_fail_msg("Failed to enter Suspend state\n");
The write will return -1 and errno is set to 16 (device busy).
It should be caused by the write function is not successfully returned
before the system suspend and the return value get messed when waking up.
As a result, It may be better to check the time passed of those few
instructions to determine whether the suspend is executed correctly for
it is pretty hard to execute those few lines for 5 seconds.
The timer to wake up the system is set to expire after 5 seconds and
no re-arm. If the timer remaining time is 0 second and 0 nano secomd,
it means the timer expired and wake the system up. Otherwise, the system
could be considered to enter the suspend state failed if there is any
remaining time.
After appling this patch, the test would not fail for it believes the
system does not go to suspend by mistake. It now could continue to the
rest part of the test after suspend.

A bunch of fixes here that came in during the merge window and the first
week of release, plus some new quirks and device IDs. There's nothing
major here, it's a bit bigger than it might've been due to there being
no fixes sent during the merge window due to your vacation.

ASoC: Fixes for v6.12
A bunch of fixes here that came in during the merge window and the first
week of release, plus some new quirks and device IDs. There's nothing
major here, it's a bit bigger than it might've been due to there being
no fixes sent during the merge window due to your vacation.
The recent addition of support for testing with the x86 specific quirk
KVM_X86_QUIRK_SLOT_ZAP_ALL disabled in the generic memslot tests broke the
build of the KVM selftests for all other architectures:
In file included from include/kvm_util.h:8,
from include/memstress.h:13,
from memslot_modification_stress_test.c:21:
memslot_modification_stress_test.c: In function ‘main’:
memslot_modification_stress_test.c:176:38: error: ‘KVM_X86_QUIRK_SLOT_ZAP_ALL’ undeclared (first use in this function)
176 | KVM_X86_QUIRK_SLOT_ZAP_ALL);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~
Add __x86_64__ guard defines to avoid building the relevant code on other
architectures.
Fixes: 61de4c34b5 ("KVM: selftests: Test memslot move in memslot_perf_test with quirk disabled")
Fixes: 218f641500 ("KVM: selftests: Allow slot modification stress test with quirk disabled")
