getaddrinfo MPTCP is recently supported in glibc and IPPROTO_MPTCP for
getaddrinfo is used in mptcp_connect.c. But in mptcp_sockopt.c and
mptcp_inq.c, IPPROTO_TCP are still used for getaddrinfo, So this patch
updates them.

mptcp_lib_get_info_value() will only print the first entry that match
the filter because of the ';q' at the end. As a consequence, the 'sed'
command could finish before the previous 'grep' one and print a 'write
error' warning because it is trying to write data to the closed pipe.
Such warnings are not interesting, they can be hidden by muting stderr
here for grep.
While at it, clearly indicate that mptcp_lib_get_info_value() will only
print the first matched entry to avoid confusions later on.

====================
pull-request: bpf-next 2025-05-02
We've added 14 non-merge commits during the last 10 day(s) which contain
a total of 13 files changed, 740 insertions(+), 121 deletions(-).
The main changes are:
1) Avoid skipping or repeating a sk when using a UDP bpf_iter,
from Jordan Rife.
2) Fixed a crash when a bpf qdisc is set in
the net.core.default_qdisc, from Amery Hung.
3) A few other fixes in the bpf qdisc, from Amery Hung.
- Always call qdisc_watchdog_init() in the .init prologue such that
the .reset/.destroy epilogue can always call qdisc_watchdog_cancel()
without issue.
- bpf_qdisc_init_prologue() was incorrectly returning an error
when the bpf qdisc is set as the default_qdisc and the mq is creating
the default_qdisc. It is now fixed.

Introduce a set of tests that exercise various bucket resume scenarios:
* remove_seen resumes iteration after removing a socket from the bucket
that we've already processed. Before, with the offset-based approach,
this test would have skipped an unseen socket after resuming
iteration. With the cookie-based approach, we now see all sockets
exactly once.
* remove_unseen exercises the condition where the next socket that we
would have seen is removed from the bucket before we resume iteration.
This tests the scenario where we need to scan past the first cookie in
our remembered cookies list to find the socket from which to resume
iteration.
* remove_all exercises the condition where all sockets we remembered
were removed from the bucket to make sure iteration terminates and
returns no more results.
* add_some exercises the condition where a few, but not enough to
trigger a realloc, sockets are added to the head of the current bucket
between reads. Before, with the offset-based approach, this test would
have repeated sockets we've already seen. With the cookie-based
approach, we now see all sockets exactly once.
* force_realloc exercises the condition that we need to realloc the
batch on a subsequent read, since more sockets than can be held in the
current batch array were added to the current bucket. This exercies
the logic inside bpf_iter_udp_realloc_batch that copies cookies into
the new batch to make sure nothing is skipped or repeated.

Add a forwarding path test for tc-taprio, based on isochron. This is
specifically intended for NICs with an offloaded data path (switchdev/DSA)
and requires taprio 'flags 2'. Also, $h1 and $h2 must support hardware
timestamping, and $h1 tc-etf offload, for isochron to work.
Packets received by a switch while the egress port has a taprio schedule
with an open gate for the traffic class must be sent right away.
Packets received by the switch while the traffic class gate must be
delayed until it opens.
Packets received by the switch must be dropped if the gate for the
traffic class never opens.
Packets should pass if the maximum SDU for the traffic class allows it,
and should be dropped otherwise.
The schedule should auto-update itself if clock jumps take place while
taprio is installed. Repeat most of the above tests after forcing two
clock jumps, one backwards (in Jan 1970) and one back into the present.
Symlink it from tools/testing/selftests/drivers/net/dsa, because usually
DSA ports have the same MAC address, and we need STABLE_MAC_ADDRS=yes
from its forwarding.config for the test to run successfully.

Make out-of-band testing (send a packet when its traffic class gate is
closed, expecting it to be delayed) more predictable by allowing the
window size to be customized by isochron_do().
From man isochron-send, the window size alters the advance time (the
delta between the transmission time of the packet, and its expected TX
time when using SO_TXTIME or tc-taprio on the sender). In absence of the
argument, isochron-send defaults to maximizing the advance time (making
it equal to the cycle length).
The default behavior is exactly what is problematic. An advance time
that is too large will make packets intended to be out-of-band still be
potentially in-band with an open gate from the schedule's previous cycle.
We need to allow that advance time to be reduced.
Perhaps a bit confusingly, isochron_do() has a shift_time argument
currently, but that does not help here. The shift time shifts both the
user space wakeup time and the expected TX time by equal amounts, it is
unable of bringing them closer to one another.
Set the window size properly for the Ocelot PSFP selftest as well.
That used to work due to a very carefully chosen SHIFT_TIME_NS.
I've re-tested that the test still works properly.

Verify that TCP connections use both routes when connecting multiple
times to a remote service over a two nexthop multipath route.
Use socat to create the connections. Use tc prio + tc filter to
count routes taken, counting SYN packets across the two egress
devices. Also verify that the saddr matches that of the device.
To avoid flaky tests when testing inherently randomized behavior,
set a low bar and pass if even a single SYN is observed on each

lib: Ensure prime numbers tests are included in KUnit test runs
Recent discussions around commit ad1afb0039 ("vlan_dev: VLAN 0 should
be treated as "no vlan tag" (802.1p packet)") have sparked the question
what happens with the DSA (and possibly other switchdev) data path when
the bridge says that ports should have no PVID VLAN, but the 8021q
module, as the result of a NETDEV_UP event, decides it should add VID 0
to the RX filter of those bridge ports. Do those bridge ports receive
packets tagged with VID 0 or not, now? We don't know, there is no test.
In the veth realm, this passes trivially, because veth is not VLAN
filtering and this, the 8021q module lacks the instinct to add VID 0 in
the first place.
In the realm of VLAN filtering NICs with no switchdev offload, this
should also pass, because the VLAN groups of the software bridge are
consulted, where it can clearly be seen that a PVID is missing, even
though the packet was initially accepted by the NIC.
The test only poses a challenge for switchdev drivers, which usually
have to program to hardware both VLANs from RX filtering, as well as
from switchdev. Especially when a switchdev port joins a VLAN-aware
bridge, it is unavoidable that it gains the NETIF_F_HW_VLAN_CTAG_FILTER
feature, i.e. any 8021q uppers that the bridge port may have must also
be committed to the RX filtering table of the interface. When a
VLAN-tagged packet is physically received by the port, it is initially
indistinguishable whether it will reach the bridge data path or the
8021q upper data path.
That is rather the final step of the new tests that we introduce.
We need to build context up to that stage, which means the following:
- we need to test that 802.1p (VID 0) tagged traffic is received in the
first place (on bridge ports with a valid PVID). This is the "8021p"
test.
- we need to test that the usual paths of reaching a configuration with
no PVID on a bridge port are all covered and they all reach the same
state.

Some distributions, such as centos stream 9, still have a version of
coreutils which does not yet support the %Hr and %Lr formats for stat(1)
[1, 2]. Running ublk selftests on these distributions results in the
following error in tests that use the _get_disk_dev_t helper:
line 23: ?r: syntax error: operand expected (error token is "?r")
To better accommodate older distributions, rewrite _get_disk_dev_t to
use the much older %t and %T formats for stat instead.

When running diag.sh in a loop, chk_dump_one will report the following
"grep: write error":

grep: write error
14 ....chk dump_one [ OK ]
15 ....chk 2->0 msk in use after flush [ OK ]
16 ....chk 2->0 cestab after flush [ OK ]
This error is caused by a broken pipe. When the output of 'ss' is processed
by grep, 'head -n 1' will exit immediately after getting the first line,
causing the subsequent pipe to close. At this time, if 'grep' is still
trying to write data to the closed pipe, it will trigger a SIGPIPE signal,
causing a write error.
One solution is not to use this problematic "head -n 1" command, but to use
mptcp_lib_get_info_value() helper defined in mptcp_lib.sh to get the value
of 'token'.
