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

previously used IDs.
Before the previous commit, the client would not have been able to

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.

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.

There are upcoming tests which verify the RX filtering of a bridge
(or bridge port), but under differing vlan_filtering conditions.
Since we currently print $h2 (the DUT) in the log_test() output, it

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".

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.

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.

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

The following patchset contains Netfilter/IPVS fixes for net:
1) Call nf_expect_get_id() to delete expectation by ID. By trial and
error it is possible to leak the LSB of the expectation address on
x86_64. This bug is a leftover when converting the existing code
to use nf_expect_get_id().
2) Incorrect initialization in pipapo set backend leads to packet
mismatches. From Florian Westphal.
3) Extend netfilter's selftests to cover for the pipapo set backend,

The TOS value that is returned to user space in the route get reply is
the one with which the lookup was performed ('fl4->flowi4_tos'). This is
fine when the matched route is configured with a TOS as it would not
match if its TOS value did not match the one with which the lookup was
performed.
However, matching on TOS is only performed when the route's TOS is not
zero. It is therefore possible to have the kernel incorrectly return a
non-zero TOS:
# ip link add name dummy1 up type dummy
# ip address add 192.0.2.1/24 dev dummy1
# ip route get fibmatch 192.0.2.2 tos 0xfc
192.0.2.0/24 tos 0x1c dev dummy1 proto kernel scope link src 192.0.2.1
Fix by instead returning the DSCP field from the FIB result structure
which was populated during the route lookup.
Output after the patch:
# ip link add name dummy1 up type dummy
# ip address add 192.0.2.1/24 dev dummy1
# ip route get fibmatch 192.0.2.2 tos 0xfc
192.0.2.0/24 dev dummy1 proto kernel scope link src 192.0.2.1
Extend the existing selftests to not only verify that the correct route
is returned, but that it is also returned with correct "tos" value (or
without it).

The other sets defined in the selftest do not trigger this bug, it only

For each added element, check 'get' works and actually returns the

After map has been filled, check all added ranges can still be

For each deleted element, check that 'get' fails.

Lately, an additional locking was added by commit c0a40097f0bc
("drivers: core: synchronize really_probe() and dev_uevent()"). The
locking protects dev_uevent() calling. This function is used to send
messages from the kernel to user space. Uevent messages notify user space
about changes in device states, such as when a device is added, removed,
or changed. These messages are used by udev (or other similar user-space
tools) to apply device-specific rules.
After reloading devlink instance, udev events should be processed. This
locking causes a short delay of udev events handling.
One example for useful udev rule is renaming ports. 'forwading.config'
can be configured to use names after udev rules are applied. Some tests run
devlink_reload() and immediately use the updated names. This worked before
the above mentioned commit was pushed, but now the delay of uevent messages
causes that devlink_reload() returns before udev events are handled and
tests fail.
Adjust devlink_reload() to not assume that udev events are already
processed when devlink reload is done, instead, wait for udev events to
ensure they are processed before returning from the function.

There are a couple of places where the test script "sleep"s to wait for
some external condition to be met.
This is error prone, specially in slow systems (identified in CI by
"KSFT_MACHINE_SLOW=yes").
To fix this, add a "ovs_wait" function that tries to execute a command
a few times until it succeeds. The timeout used is set to 5s for
"normal" systems and doubled if a slow CI machine is detected.
This should make the following work:
$ vng --build \
--config tools/testing/selftests/net/config \
--config kernel/configs/debug.config
$ vng --run . --user root -- "make -C tools/testing/selftests/ \

Centralize the _GNU_SOURCE definition to CFLAGS in lib.mk. Remove
redundant defines from Makefiles that import lib.mk. Convert any usage of
"#define _GNU_SOURCE 1" to "#define _GNU_SOURCE".
This uses the form "-D_GNU_SOURCE=", which is equivalent to
"#define _GNU_SOURCE".
Otherwise using "-D_GNU_SOURCE" is equivalent to "-D_GNU_SOURCE=1" and
"#define _GNU_SOURCE 1", which is less commonly seen in source code and
would require many changes in selftests to avoid redefinition warnings.

In selftests/net/msg_zerocopy.c, it has a while loop keeps calling sendmsg
on a socket with MSG_ZEROCOPY flag, and it will recv the notifications
until the socket is not writable. Typically, it will start the receiving
process after around 30+ sendmsgs. However, as the introduction of commit
dfa2f0483360 ("tcp: get rid of sysctl_tcp_adv_win_scale"), the sender is
always writable and does not get any chance to run recv notifications.
The selftest always exits with OUT_OF_MEMORY because the memory used by
opt_skb exceeds the net.core.optmem_max. Meanwhile, it could be set to a
different value to trigger OOM on older kernels too.
Thus, we introduce "cfg_notification_limit" to force sender to receive
notifications after some number of sendmsgs.

The openvswitch selftest is difficult to debug for anyone that isn't

sparsely populated and it takes some time to understand where a failure
