Nothing special, just test how long insertion of x policies takes.
This should ideally show linear insertion speeds.
Do not run this by default, it has little value, but it can be useful to
check for insertion speed chahnges when altering the xfrm policy db
implementation.

A few tests check if nettest exists in the $PATH before adding
$PWD to $PATH and re-checking. They don't discard stderr on
the first check (and nettest is built as part of selftests,
so it's pretty normal for it to not be available in system $PATH).
This leads to output noise:
which: no nettest in (/home/virtme/tools/fs/bin:/home/virtme/tools/fs/sbin:/home/virtme/tools/fs/usr/bin:/home/virtme/tools/fs/usr/sbin:/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin)
Add a common helper for the check which does silence stderr.
There is another small functional change hiding here, because pmtu.sh
and fib_rule_tests.sh used to return from the test case rather than
completely exit. Building nettest is not hard, there should be no need
to maintain the ability to selectively skip cases in its absence.

This case was not covered, and the wrong ID was set before the previous
commit.
The rest is not modified, it is just that it will increase the code
coverage.
The right address ID can be verified by looking at the packet traces. We
could automate that using Netfilter with some cBPF code for example, but
that's always a bit cryptic. Packetdrill seems better fitted for that.

This test extends "delete and re-add" to validate the previous commit. A
new 'subflow' endpoint is added, but the subflow request will be
rejected. The result is that no subflow will be established from this
address.
Later, the endpoint is removed and re-added after having cleared the
firewall rule. Before the previous commit, the client would not have
been able to create this new subflow.
While at it, extra checks have been added to validate the expected
numbers of MPJ and RM_ADDR.

Looking at timestamped output of netdev CI reveals that
most of the time in forwarding tests for custom route
hashing is spent on a single case, namely the test which
uses ping (mausezahn does not support flow labels).
On a non-debug kernel we spend 714 of 730 total test
runtime (97%) on this test case. While having flow label
support in a traffic gen tool / mausezahn would be best,
we can significantly speed up the loop by putting ip vrf exec
outside of the iteration.
In a test of 1000 pings using a normal loop takes 50 seconds
to finish. While using:
ip vrf exec $vrf sh -c "$loop-body"
takes 12 seconds (1/4 of the time).
Some of the slowness is likely due to our inefficient virtualization
setup, but even on my laptop running "ip link help" 16k times takes
25-30 seconds, so I think it's worth optimizing even for fastest
setups.

The bridge VLAN implementation w.r.t. VLAN protocol is described in
merge commit 1a0b20b25732 ("Merge branch 'bridge-next'"). We are only
sensitive to those VLAN tags whose TPID is equal to the bridge's
vlan_protocol. Thus, an 802.1ad VLAN should be treated as 802.1Q-untagged.
Add 3 tests which validate that:
- 802.1ad-tagged traffic is learned into the PVID of an 802.1Q-aware
bridge
- Double-tagged traffic is forwarded when just the PVID of the port is
present in the VLAN group of the ports
- Double-tagged traffic is not forwarded when the PVID of the port is
absent from the VLAN group of the ports
The test passes with both veth and ocelot.

A breakage in the felix DSA driver shows we do not have enough test
coverage. More generally, it is sufficiently special that it is likely
drivers will treat it differently.
This is not meant to be a full PTP test, it just makes sure that PTP
packets sent to the different addresses corresponding to their profiles
are received correctly. The local_termination selftest seemed like the
most appropriate place for this addition.
PTP RX/TX in some cases makes no sense (over a bridge) and this is why
$skip_ptp exists. And in others - PTP over a bridge port - the IP stack
needs convincing through the available bridge netfilter hooks to leave
the PTP packets alone and not stolen by the bridge rx_handler. It is
safe to assume that users have that figured out already. This is a
driver level test, and by using tcpdump, all that extra setup is out of
scope here.
send_non_ip() was an unfinished idea; written but never used.
Replace it with a more generic send_raw(), and send 3 PTP packet types
times 3 transports.

xfail_on_veth() for this test is an incorrect approximation which gives
false positives and false negatives.
When local_termination fails with "reception succeeded, but should have failed",
it is because the DUT ($h2) accepts packets even when not configured as
promiscuous. This is not something specific to veth; even the bridge
behaves that way, but this is not captured by the xfail_on_veth test.
The IFF_UNICAST_FLT flag is not explicitly exported to user space, but
it can somewhat be determined from the interface's behavior. We have to
create a macvlan upper with a different MAC address. This forces a
dev_uc_add() call in the kernel. When the unicast filtering list is
not empty, but the device doesn't support IFF_UNICAST_FLT,
__dev_set_rx_mode() force-enables promiscuity on the interface, to
ensure correct behavior (that the requested address is received).
We can monitor the change in the promiscuity flag and infer from it
whether the device supports unicast filtering.
There is no equivalent thing for allmulti, unfortunately. We never know
what's hiding behind a device which has allmulti=off. Whether it will
actually perform RX multicast filtering of unknown traffic is a strong
"maybe". The bridge driver, for example, completely ignores the flag.
We'll have to keep the xfail behavior, but instead of XFAIL on just
veth, always XFAIL.

Add more coverage to the local termination selftest as follows:
- 8021q upper of $h2
- 8021q upper of $h2, where $h2 is a port of a VLAN-unaware bridge
- 8021q upper of $h2, where $h2 is a port of a VLAN-aware bridge
- 8021q upper of VLAN-unaware br0, which is the upper of $h2
- 8021q upper of VLAN-aware br0, which is the upper of $h2
Especially the cases with traffic sent through the VLAN upper of a
VLAN-aware bridge port will be immediately relevant when we will start
transmitting PTP packets as an additional kind of traffic.

The current bridge() test is for packet reception on a VLAN-unaware
bridge. Some things are different enough with VLAN-aware bridges that
it's worth renaming this test into vlan_unaware_bridge(), and add a new
vlan_aware_bridge() test.
The two will share the same implementation: bridge() becomes a common
function, which receives $vlan_filtering as an argument. Rename it to
test_bridge() at the same time, because just bridge() pollutes the
global namespace and we cannot invoke the binary with the same name from
the iproute2 package currently.

When deleting netns, it is possible to still have some tasks running,
e.g. background tasks like tcpdump running in the background, not
stopped because the test has been interrupted.
Before deleting the netns, it is then safer to kill all attached PIDs,
if any. That should reduce some noises after the end of some tests, and
help with the debugging of some issues. That's why this modification is
seen as a "fix".

Add tests that exercise full 16 bits of NH weight.
To test the 255:65535, it is necessary to run more packets than for the
other tests. On a debug kernel, the test can take up to a minute, therefore
avoid the test when KSFT_MACHINE_SLOW.

Add new @ksft_disruptive decorator to mark the tests that might
be disruptive to the system. Depending on how well the previous
test works in the CI we might want to disable disruptive tests
by default and only let the developers run them manually.
KSFT framework runs disruptive tests by default. DISRUPTIVE=False
environment (or config file) can be used to disable these tests.
ksft_setup should be called by the test cases that want to use
new decorator (ksft_setup is only called via NetDrvEnv/NetDrvEpEnv for now).
In the future we can add similar decorators to, for example, avoid
running slow tests all the time. And/or have some option to run
only 'fast' tests for some sort of smoke test scenario.

It should be quite uncommon to set both the subflow and the signal
flags: the initiator of the connection is typically the one creating new
subflows, not the other peer, then no need to announce additional local
addresses, and use it to create subflows.
But some people might be confused about the flags, and set both "just to
be sure at least the right one is set". To verify the previous fix, and
avoid future regressions, this specific case is now validated: the
client announces a new address, and initiates a new subflow from the
same address.
While working on this, another bug has been noticed, where the client
reset the new subflow because an ADD_ADDR echo got received as the 3rd
ACK: this new test also explicitly checks that no RST have been sent by
the client and server.

commit: this patch here is not fixing anything wrong in the selftests,

In the following commit, the client will initiate the ADD_ADDR, instead
of the server. We need to way to verify the ADD_ADDR have been correctly
sent.
Note: the default expected counters for when the port number is given
are never changed by the caller, no need to accept them as parameter
then.

Before the previous commit, 'signal' endpoints with the 'backup' flag
were ignored when sending the MP_JOIN.
The MPTCP Join selftest has then been modified to validate this case:
the "single address, backup" test, is now validating the MP_JOIN with a
backup flag as it is what we expect it to do with such name. The
previous version has been kept, but renamed to "single address, switch
to backup" to avoid confusions.
The "single address with port, backup" test is also now validating the
MPJ with a backup flag, which makes more sense than checking the switch
to backup with an MP_PRIO.
The "mpc backup both sides" test is now validating that the backup flag
is also set in MP_JOIN from and to the addresses used in the initial
subflow, using the special ID 0.

commit: this patch here is not fixing anything wrong in the selftests,

A peer can notify the other one that a subflow has to be treated as
"backup" by two different ways: either by sending a dedicated MP_PRIO
notification, or by setting the backup flag in the MP_JOIN handshake.
The selftests were previously monitoring the former, but not the latter.
This is what is now done here by looking at these new MIB counters when
validating the 'backup' cases:
MPTcpExtMPJoinSynBackupRx
MPTcpExtMPJoinSynAckBackupRx
