It is now added by the MPTCP lib automatically, see the parent commit.
The time in the TAP output might be slightly different from the one
displayed before, but that's OK.

It adds 'time=<N>ms' in the diagnostic data of the TAP output, e.g.
ok 1 - pm_netlink: defaults addr list # time=9ms
This addition is useful to quickly identify which subtests are taking a
longer time than the others, or more than expected.
Note that there are no specific formats to follow to show this time
according to the TAP 13 [1], TAP 14 [2] and KTAP [3] specifications.
Let's then define this one here.

When I was trying to modify the tx timestamping feature, I found that
running "./txtimestamp -4 -C -L 127.0.0.1" didn't reflect the error:
I succeeded to generate timestamp stored in the skb but later failed
to report it to the userspace (which means failed to put css into cmsg).
It can happen when someone writes buggy codes in __sock_recv_timestamp(),
for example.
After adding the check so that running ./txtimestamp will reflect the
result correctly like this if there is a bug in the reporting phase:
protocol: TCP
payload: 10
server port: 9000
family: INET
test SND
USR: 1725458477 s 667997 us (seq=0, len=0)

Failed to report timestamps
USR: 1725458477 s 818416 us (seq=0, len=0)

...
In the future, it will help us detect whether the new coming patch has
bugs or not.

The test is supposed to be killed before the end, which will likely
cause "Connection reset by peer" errors. It is confusing, especially
because in case of real transfer errors, the test will not be marked as
failed. But that's OK, there are many other tests checking that.

Instead of displaying 'invert' when looking at some events like MP_FAIL,
MP_FASTCLOSE, MP_RESET, RM_ADDR, which is a bit vague because they are
not traditionnaly sent from one side, the host being checked is now
printed.
For the ADD_ADDR, only display the host when it is the client sending
it, which is more unusual.
Also before, the 'invert' message was printed after a few checks, but it
was not clear which ones exactly.

A few new MPJoinSynTx MIB counters have been added in a previous commit.
They are being validated here in mptcp_join.sh selftest, each time the
number of received MPJ are checked.
Most of the time, the number of sent SYN+MPJ is the same as the received
ones. But sometimes, there are more, because there are dropped, or there
are errors.
While at it, the "no MPC reuse with single endpoint" subtest has been
modified to force a bind() error.

The sctp selftest is very slow on debug kernels.
Its possible that the nf_queue listener program exits due to timeout
before first sctp packet is processed.
In this case socat hangs until script times out.
Fix this by removing the -t option where possible and kill the test
program once the file transfer/socat has exited.
-t sets SO_RCVTIMEO, its inteded for the 'ping' part of the selftest
where we want to make sure that packets get reinjected properly without
skipping a second queue request.
While at it, add a helper to compare the (binary) files instead of diff.
The 'diff' part was copied from a another sub-test that compares text.
Let helper dump file sizes on error so we can see the progress made.
Tested on an old 2010-ish box with a debug kernel and 100 iterations.
This is a followup to the earlier filesize reduction change.

commit: when the 'signal' endpoint linked to the initial subflow (ID 0)
is re-added multiple times, it will re-send the ADD_ADDR with id 0. The
client should still be able to re-create this subflow, even if the

The initial subflow has a special local ID: 0. It is specific per
connection.
When a global endpoint is deleted and re-added later, it can have a
different ID, but the kernel should still use the ID 0 if it corresponds
to the initial address.
This test validates this behaviour: the endpoint linked to the initial
subflow is removed, and re-added with a different ID.
Note that removing the initial subflow will not decrement the 'subflows'
counters, which corresponds to the *additional* subflows. On the other
hand, when the same endpoint is re-added, it will increment this
counter, as it will be seen as an additional subflow this time.

Thanks to the previous commit, the MPTCP subflows are now closed on both
directions even when only the MPTCP path-manager of one peer asks for
their closure.
In the two tests modified here -- "userspace pm add & remove address"
and "userspace pm create destroy subflow" -- one peer is controlled by
the userspace PM, and the other one by the in-kernel PM. When the
userspace PM sends a RM_ADDR notification, the in-kernel PM will
automatically react by closing all subflows using this address. Now,
thanks to the previous commit, the subflows are properly closed on both
directions, the userspace PM can then no longer closes the same
subflows if they are already closed. Before, it was OK to do that,
because the subflows were still half-opened, still OK to send a RM_ADDR.
In other words, thanks to the previous commit closing the subflows, an
error will be returned to the userspace if it tries to close a subflow
that has already been closed. So no need to run this command, which mean
that the linked counters will then not be incremented.
These tests are then no longer sending both a RM_ADDR, then closing the
linked subflow just after. The test with the userspace PM on the server
side is now removing one subflow linked to one address, then sending
a RM_ADDR for another address. The test with the userspace PM on the
client side is now only removing the subflow that was previously
created.

Setup trace points, add a new ftrace instance in order to not interfere
with the rest of the system, filtering by net namespace cookies.
Raise a new background thread that parses trace_pipe, matches them with
the list of expected events.
Wiring up trace events to selftests provides another insight if there is
anything unexpected happining in the tcp-ao code (i.e. key rotation when
it's not expected).
Note: in real programs libtraceevent should be used instead of this
manual labor of setting ftrace up and parsing. I'm not using it here
as I don't want to have an .so library dependency that one would have to
bring into VM or DUT (Device Under Test). Please, don't copy it over

On tests that are expecting failure the timeout value is
TEST_RETRANSMIT_SEC == 1 second. Which is big enough for most of devices
under tests. But on a particularly slow machine/VM, 1 second might be
not enough for another thread to be scheduled and attempt to connect().
It is not a problem for tests that expect connect() to succeed as
the timeout value for them (TEST_TIMEOUT_SEC) is intentionally bigger.
One obvious way to solve this would be to increase TEST_RETRANSMIT_SEC.
But as all tests would increase the timeouts, that's going to sum up.
But here is less obvious way that keeps timeouts for expected connect()
failures low: just synchronize the two threads, which will assure that
before counter checks the other thread got a chance to run and timeout
on connect(). The expected increase of the related counter for listen()
socket will yet test the expected failure.
Never happens on my machine, but I suppose the majority of netdev's
connect-deny-* flakes [1] are caused by this.
Prevents the following testing issue:

It turns to be that open_netns() is called rarely from the child-thread
and more often from parent-thread. Yet, on initialization of kconfig
checks, either of threads may reach kconfig_lock mutex first.
VRF-related checks do create a temporary ksft-check VRF in
an unshare()'d namespace and than setns() back to the original.
As original was opened from "/proc/self/ns/net", it's valid for
thread-leader (parent), but it's invalid for the child, resulting
in the following failure on tests that check has_vrfs() support:
> # ok 54 TCP-AO required on socket + TCP-MD5 key: prefailed as expected: Key was rejected by service
> # not ok 55 # error 381[unsigned-md5.c:24] Failed to add a VRF: -17
> # not ok 56 # error 383[unsigned-md5.c:33] Failed to add a route to VRF: -22: Key was rejected by service
> not ok 1 selftests: net/tcp_ao: unsigned-md5_ipv6 # exit=1
Use "/proc/thread-self/ns/net" which is valid for any thread.

Most of the functions in tcp-ao lib/ return negative errno or -1 in case
of a failure. That creates inconsistencies in lib/kconfig, which saves
what was the error code. As well as the uninitialized kconfig value is
-1, which also may be the result of a check.
Define KCONFIG_UNKNOWN and save negative return code, rather than
libc-style errno.

Instead of pre-allocating a fixed-sized buffer of TEST_MSG_BUFFER_SIZE
and printing into it, call vsnprintf() with str = NULL, which will
return the needed size of the buffer. This hack is documented in
man 3 vsnprintf.
Essentially, in C++ terms, it re-invents std::stringstream, which is
going to be used to print different tracing paths and formatted strings.
Use it straight away in __test_print() - which is thread-safe version of
printing in selftests.

Pablo Neira Ayuso says:
====================
Netfilter updates for net-next
The following batch contains Netfilter updates for net-next:
Patch #1 fix checksum calculation in nfnetlink_queue with SCTP,
segment GSO packet since skb_zerocopy() does not support
GSO_BY_FRAGS, from Antonio Ojea.
Patch #2 extend nfnetlink_queue coverage to handle SCTP packets,
from Antonio Ojea.
Patch #3 uses consume_skb() instead of kfree_skb() in nfnetlink,
from Donald Hunter.
Patch #4 adds a dedicate commit list for sets to speed up
intra-transaction lookups, from Florian Westphal.
Patch #5 skips removal of element from abort path for the pipapo
backend, ditching the shadow copy of this datastructure
is sufficient.
Patch #6 moves nf_ct_netns_get() out of nf_conncount_init() to
let users of conncoiunt decide when to enable conntrack,
this is needed by openvswitch, from Xin Long.
Patch #7 pass context to all nft_parse_register_load() in
preparation for the next patch.
Patches #8 and #9 reject loads from uninitialized registers from
control plane to remove register initialization from
datapath. From Florian Westphal.

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.

After having flushed endpoints that didn't cause the creation of new

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.

Later, the server will delete this extra endpoint, and set a new one,
with a valid address, but re-using the same ID. Before the previous
