Setting a vCPU's MP state to KVM_MP_STATE_STOPPED has the effect of
powering off the vCPU. Rather than using the vCPU init feature flag, use
the KVM_SET_MP_STATE ioctl to power off the target vCPU.

Check userspace PM behavior to ensure ADD_ADDR echoes are only sent when
there is an active userspace daemon. If the daemon is restarting or
hasn't loaded yet, the missing echo will cause the peer to retransmit
the ADD_ADDR - and hopefully the daemon will be ready to receive it at
that later time.

Pull seccomp selftest fix from Kees Cook:
- Avoid using stdin for read syscall testing (Jann Horn)
* tag 'seccomp-v5.18-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux:
selftests/seccomp: Don't call read() on TTY from background pgrp

This verifies that if a filter is set up with the wait killable feature
that it obeys the semantics that non-fatal signals are ignored during
a notification after the notification is received.
Cases tested:
* Non-fatal signal prior to receive
* Non-fatal signal during receive
* Fatal signal after receive
The normal signal handling is tested in user_notification_signal. That
behaviour remains unchanged.
On an unsupported kernel, these tests will immediately bail as it relies
on a new seccomp flag.

operational
In emulated environments, the bridge ports enslaved to br1 get a carrier
before changing br1's PVID. This means that by the time the PVID is
changed, br1 is already operational and configured with an IPv6
link-local address.
When the test is run with netdevs registered by mlxsw, changing the PVID
is vetoed, as changing the VID associated with an existing L3 interface
is forbidden. This restriction is similar to the 8021q driver's
restriction of changing the VID of an existing interface.
Fix this by taking br1 down and bringing it back up when it is fully
configured.
With this fix, the test reliably passes on top of both the SW and HW
data paths (emulated or not).

The Felix VSC9959 switch in NXP LS1028A supports the tc-gate action
which enforced time-based access control per stream. A stream as seen by
this switch is identified by {MAC DA, VID}.
We use the standard forwarding selftest topology with 2 host interfaces
and 2 switch interfaces. The host ports must require timestamping non-IP
packets and supporting tc-etf offload, for isochron to work. The
isochron program monitors network sync status (ptp4l, phc2sys) and
deterministically transmits packets to the switch such that the tc-gate
action either (a) always accepts them based on its schedule, or
(b) always drops them.
I tried to keep as much of the logic that isn't specific to the NXP
LS1028A in a new tsn_lib.sh, for future reuse. This covers
synchronization using ptp4l and phc2sys, and isochron.
The cycle-time chosen for this selftest isn't particularly impressive
(and the focus is the functionality of the switch), but I didn't really
know what to do better, considering that it will mostly be run during
debugging sessions, various kernel bloatware would be enabled, like
lockdep, KASAN, etc, and we certainly can't run any races with those on.
I tried to look through the kselftest framework for other real time
applications and didn't really find any, so I'm not sure how better to
prepare the environment in case we want to go for a lower cycle time.
At the moment, the only thing the selftest is ensuring is that dynamic
frequency scaling is disabled on the CPU that isochron runs on. It would
probably be useful to have a blacklist of kernel config options (checked
through zcat /proc/config.gz) and some cyclictest scripts to run
beforehand, but I saw none of those.

Currently, alloc_anon_noexit() calls alloc_anon() which instantly frees
the allocated memory. alloc_anon_noexit() is usually used with
cg_run_nowait() to run a process in the background that allocates
memory. It makes sense for the background process to keep the memory
allocated and not instantly free it (otherwise there is no point of
running it in the background).

Since commit 92d25637a3a4 ("kselftest: signal all child processes"), tests
are executed in background process groups. This means that trying to read
from stdin now throws SIGTTIN when stdin is a TTY, which breaks some
seccomp selftests that try to use read(0, NULL, 0) as a dummy syscall.
The simplest way to fix that is probably to just use -1 instead of 0 as
the dummy read()'s FD.

These might not be issues yet, but they make the script more fragile.
Also by fixing them we give a better example to future readers, who might
copy/paste or otherwise re-use snippets from our script.
- Use "read -r", since we don't ever want read to be interpreting '\'
characters as escape sequences...
- Quote variables, to deal with spaces properly.
- Use $() instead of the older and harder-to-nest ``.
- Get rid of superfluous "$" prefixes inside arithmetic $(()).

Previously, each test printed out its own header, dealt with its own
return code, etc. By just putting this standard stuff in a function, we
can delete > 300 lines from the script.
This also makes adding future tests easier. And, it gets rid of various
inconsistencies that already exist:
- Some tests correctly deal with ksft_skip, but others don't.
- Some tests just print the executable name, others print arguments, and
yet others print some comment in the header.
- Most tests print out a header with two separator lines, but not the
HMM smoke test or the memfd_secret test, which only print one.
- We had a redundant "exit" at the end, with all the boilerplate it's an
easy oversight.

After commit 0e4b01df8659 ("mm, memcg: throttle allocators when failing
reclaim over memory.high") allocating memory over memory.high became very
time consuming. But it's exactly what the memory.high test from cgroup
kselftests is doing: it tries to allocate 100M with 30M memory.high value.
It takes forever to complete.
In order to keep it passing (or failing) in a reasonable amount of time
let's try to allocate only a little over 30M: 31M to be precise.

Patch series "mm: memcg kselftests fixes".
This patch (of 4):
Commit 9852ae3fe529 ("mm, memcg: consider subtrees in memory.events") made
memory.events recursive: all events are propagated upwards by the tree.
It was a change in semantics.
It broke the oom group leaf events test: it assumes that after an OOM the
oom_kill counter is zero on parent's level.
Let's adjust the test: it should have similar expectations for the child
and parent levels.
The test passes after this fix.

Add new or modify existing SEC() definitions to be target-less and
validate that libbpf handles such program definitions correctly.
For kprobe/kretprobe we also add explicit test that generic
bpf_program__attach() works in cases when kprobe definition contains
proper target. It wasn't previously tested as selftests code always
explicitly specified the target regardless.

Pull networking fixes from Jakub Kicinski:
"Including fixes from bluetooth, bpf and netfilter.
Current release - new code bugs:
- bridge: switchdev: check br_vlan_group() return value
- use this_cpu_inc() to increment net->core_stats, fix preempt-rt
Previous releases - regressions:
- eth: stmmac: fix write to sgmii_adapter_base
Previous releases - always broken:
- netfilter: nf_conntrack_tcp: re-init for syn packets only,
resolving issues with TCP fastopen
- tcp: md5: fix incorrect tcp_header_len for incoming connections
- tcp: fix F-RTO may not work correctly when receiving DSACK
- tcp: ensure use of most recently sent skb when filling rate samples
- tcp: fix potential xmit stalls caused by TCP_NOTSENT_LOWAT
- virtio_net: fix wrong buf address calculation when using xdp
- xsk: fix forwarding when combining copy mode with busy poll
- xsk: fix possible crash when multiple sockets are created
- bpf: lwt: fix crash when using bpf_skb_set_tunnel_key() from
bpf_xmit lwt hook
- sctp: null-check asoc strreset_chunk in sctp_generate_reconf_event
- wireguard: device: check for metadata_dst with skb_valid_dst()
- netfilter: update ip6_route_me_harder to consider L3 domain
- gre: make o_seqno start from 0 in native mode
- gre: switch o_seqno to atomic to prevent races in collect_md mode
Misc:
- add Eric Dumazet to networking maintainers
- dt: dsa: realtek: remove realtek,rtl8367s string
- netfilter: flowtable: Remove the empty file"

Currently the arm64 floating point tests don't support out of tree builds
due to two quirks of the kselftest build system. One is that when building
a program from multiple files we shouldn't separately compile the main
program to an object file as that will result in the pattern rule not
matching when adjusted for the output directory. The other is that we also
need to include $(OUTPUT) in the names of the binaries when specifying the
dependencies in order to ensure that they get picked up with O=.
Rewrite the dependencies for the executables to fix these issues. The
kselftest build system will ensure OUTPUT is always defined.
