RFC 9131 changes default behaviour of handling RX of NA messages when the
corresponding entry is absent in the neighbour cache. The current
implementation is limited to accept just unsolicited NAs. However, the
RFC is more generic where it also accepts solicited NAs. Both types
should result in adding a STALE entry for this case.
Expand accept_untracked_na behaviour to also accept solicited NAs to
be compliant with the RFC and rename the sysctl knob to
accept_untracked_na.

The psock_snd test sends and receives packets over loopback, and
the test results depend on parameter settings:
Set rp_filter=0,
or set rp_filter=1 and accept_local=1
so that the test will pass. Otherwise, this test will fail with
Resource temporarily unavailable:
sudo ./psock_snd.sh
dgram
tx: 128
rx: 142
./psock_snd: recv: Resource temporarily unavailable
For most distro kernel releases(like Ubuntu or Centos), the parameter
rp_filter is enabled by default, so it's necessary to enable the
parameter lo.accept_local in psock_snd test. And this test runs
inside a netns, changing a sysctl is fine.

bhash entry
This test populates the bhash table for a given port with
MAX_THREADS * MAX_CONNECTIONS sockets, and then times how long
a bind request on the port takes.
When populating the bhash table, we create the sockets and then bind
the sockets to the same address and port (SO_REUSEADDR and SO_REUSEPORT
are set). When timing how long a bind on the port takes, we bind on a
different address without SO_REUSEPORT set. We do not set SO_REUSEPORT
because we are interested in the case where the bind request does not
go through the tb->fastreuseport path, which is fragile (eg
tb->fastreuseport path does not work if binding with a different uid).
To run the test locally, I did:
* ulimit -n 65535000
* ip addr add 2001:0db8:0:f101::1 dev eth0
* ./bind_bhash_test 443

Commit 49bb39bddad2 ("selftests: fib_nexthops: Make the test more robust")
increased the timeout of ping commands to 5 seconds, to make the test
more robust. Make the timeout configurable using '-w' argument to allow
user to change it depending on the system that runs the test. Some systems
suffer from slow forwarding performance, so they may need to change the
timeout.

Add the multiple subflows test case for MP_FAIL, to test the MP_FAIL
reset case. Use the test_linkfail value to make 1024KB test files.
Invoke reset_with_fail() to use 'iptables' and 'tc action pedit' rules
to produce the bit flips to trigger the checksum failures on ns2eth2.
Add delays on ns2eth1 to make sure more data can translate on ns2eth2.
The check_invert flag is enabled in reset_with_fail(), so this test
prints out the inverted bytes, instead of the file mismatch errors.
Invoke pedit_action_pkts() to get the numbers of the packets edited
by the tc pedit actions, and print this numbers to the output.

This patch adds a test that has 300 VIPs listening on port 443.
Each VIP:443 will have 80 listening socks by using SO_REUSEPORT.
Thus, it will have 24000 listening socks.
Before removing the port only listening_hash, all socks will be in the
same port 443 bucket and inet_reuseport_add_sock() spends much time to
walk through the bucket. After removing the port only listening_hash
and move all usage to the port+addr lhash2, each bucket in the
ideal case has 80 sk which is much smaller than before.
Here is the test result from a qemu:
Before: listen 24000 socks took 210.210485362 (~210s)
After: listen 24000 socks took 0.207173 (~210ms)

non-offloaded h2
The host interfaces $h1 and $h2 don't have to be switchdev interfaces,
but due to the fact that we pass $tcflags which may have the value of
"skip_sw", we force $h2 to offload a drop rule for dst_ip, something
which it may not be able to do.
The selftest only wants to verify the hit count of this rule as a means
of figuring out whether the packet was received, so remove the $tcflags
for it and let it be done in software.

The 'ping' utility is able to manage two kind of sockets (raw or icmp),
depending on the sysctl ping_group_range. By default, ping_group_range is
set to '1 0', which forces ping to use an ip raw socket.
Let's replay the ping tests by allowing 'ping' to use the ip icmp socket.
After the previous patch, ipv4 tests results are the same with both kinds
of socket. For ipv6, there are a lot a new failures (the previous patch
fixes only two cases).

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.

These tests ensure that the in-kernel path manager is bypassed when
the userspace path manager is configured. Kernel code is still
responsible for ADD_ADDR echo, so also make sure that's working.

This patch extends chk_fail_nr to check the MP_FAIL response mibs.
Add a new argument invert for chk_fail_nr to allow it can check the
MP_FAIL TX and RX mibs from the opposite direction.
When the infinite map is received before the MP_FAIL response, the
response will be lost. A '-' can be added into fail_tx or fail_rx to
represent that MP_FAIL response TX or RX can be lost when doing the
checks.

Add the single subflow test case for MP_FAIL, to test the infinite
mapping case. Use the test_linkfail value to make 128KB test files.
Add a new function reset_with_fail(), in it use 'iptables' and 'tc
action pedit' rules to produce the bit flips to trigger the checksum
failures. Set validate_checksum to enable checksums for the MP_FAIL
tests without passing the '-C' argument. Set check_invert flag to
enable the invert bytes check for the output data in check_transfer().
Instead of the file mismatch error, this test prints out the inverted
bytes.
Add a new function pedit_action_pkts() to get the numbers of the packets
edited by the tc pedit actions. Print this numbers to the output.
Also add the needed kernel configures in the selftests config file.

This tests the capability of switch ports to filter out undesired
traffic. Different drivers are expected to have different capabilities
here (so some may fail and some may pass), yet the test still has some
value, for example to check for regressions.
There are 2 kinds of failures, one is when a packet which should have
been accepted isn't (and that should be fixed), and the other "failure"
(as reported by the test) is when a packet could have been filtered out
(for being unnecessary) yet it was received.
The bridge driver fares particularly badly at this test:
TEST: br0: Unicast IPv4 to primary MAC address [ OK ]
TEST: br0: Unicast IPv4 to macvlan MAC address [ OK ]
TEST: br0: Unicast IPv4 to unknown MAC address [FAIL]
reception succeeded, but should have failed
TEST: br0: Unicast IPv4 to unknown MAC address, promisc [ OK ]
TEST: br0: Unicast IPv4 to unknown MAC address, allmulti [FAIL]
reception succeeded, but should have failed
TEST: br0: Multicast IPv4 to joined group [ OK ]
TEST: br0: Multicast IPv4 to unknown group [FAIL]
reception succeeded, but should have failed
TEST: br0: Multicast IPv4 to unknown group, promisc [ OK ]
TEST: br0: Multicast IPv4 to unknown group, allmulti [ OK ]
TEST: br0: Multicast IPv6 to joined group [ OK ]
TEST: br0: Multicast IPv6 to unknown group [FAIL]
reception succeeded, but should have failed
TEST: br0: Multicast IPv6 to unknown group, promisc [ OK ]
TEST: br0: Multicast IPv6 to unknown group, allmulti [ OK ]
mainly because it does not implement IFF_UNICAST_FLT. Yet I still think
having the test (with the failures) is useful in case somebody wants to
tackle that problem in the future, to make an easy before-and-after
comparison.

Bombard a standalone switch port with various kinds of traffic to ensure
it is really standalone and doesn't leak packets to other switch ports.
Also check for switch ports in different bridges, and switch ports in a
VLAN-aware bridge but having different pvids. No forwarding should take
place in either case.

interface
Pinging an IPv6 link-local multicast address selects the link-local
unicast address of the interface as source, and we'd like to monitor for
that in tcpdump.
Add a helper to the forwarding library which retrieves the link-local
IPv6 address of an interface, to make that task easier.

Extend the forwarding library with calls to some small C programs which
join an IP multicast group and send some packets to it. Both IPv4 and
IPv6 groups are supported. Use cases range from testing IGMP/MLD
snooping, to RX filtering, to multicast routing.
Testing multicast traffic using msend/mreceive is intended to be done
using tcpdump.

Extend tcpdump_start() & C:o to handle multiple instances. Useful when
observing bridge operation, e.g., unicast learning/flooding, and any
case of multicast distribution (to these ports but not that one ...).
This means the interface argument is now a mandatory argument to all
tcpdump_*() functions, hence the changes to the ocelot flower test.

For some use-cases we may want to change the tcpdump flags used in
tcpdump_start(). For instance, observing interfaces without the PROMISC
flag, e.g. to see what's really being forwarded to the bridge interface.

By default, DSA switch ports inherit their MAC address from the DSA
master.
This works well for practical situations, but some selftests like
bridge_vlan_unaware.sh loop back 2 standalone DSA ports with 2 bridged
DSA ports, and require the bridge to forward packets between the
standalone ports.
Due to the bridge seeing that the MAC DA it needs to forward is present
as a local FDB entry (it coincides with the MAC address of the bridge
ports), the test packets are not forwarded, but terminated locally on
br0. In turn, this makes the ping and ping6 tests fail.
Address this by introducing an option to have stable MAC addresses.
When mac_addr_prepare is called, the current addresses of the netifs are
saved and replaced with 00:01:02:03:04:${netif number}. Then when
mac_addr_restore is called at the end of the test, the original MAC
addresses are restored. This ensures that the MAC addresses are unique,
which makes the test pass even for DSA ports.
The usage model is for the behavior to be opt-in via STABLE_MAC_ADDRS,
which DSA should set to true, all others behave as before. By hooking
the calls to mac_addr_prepare and mac_addr_restore within the forwarding
lib itself, we do not need to patch each individual selftest, the only
requirement is that pre_cleanup is called.
