There are currently no kernel tests that verify the effect of setting
the enabled team driver option. In a followup patch, there will be
changes to this option, so it will be important to make sure it still
behaves as it does now.
The test verifies that tcp continues to work across two different team
devices in separate network namespaces, even when member links are
manually disabled.

The querier-interval test adds h1 (currently a slave of the VRF created
by simple_if_init) to a temporary bridge br1 acting as an outside IGMP
querier. The kernel VRF driver (drivers/net/vrf.c) calls cycle_netdev()
on every slave add and remove, toggling the interface admin-down then up.
Phylink takes the PHY down during the admin-down half of that cycle.
Since h1 and swp1 are cable-connected, swp1 also loses its link may need
several seconds to re-negotiate.
Use setup_wait_dev $h1 0 which waits for h1 to return to UP state, so the
test can rely on the link being back up at this point.

Update some helpers so that they are capable to run commands on
different targets than the local one. This patch makes the necesasy
modification for those helpers / sections of code which are needed for
the ethtool_rmon.sh test that will be converted in the next patches.
For example, mac_addr_prepare() and mac_addr_restore() used when
STABLE_MAC_ADDRS=yes need to ensure stable MAC addresses on interfaces
located even in other namespaces. In order to do that, append the 'ip
link' commands with a 'run_on $dev' tag.
The same run_on is necessary also when verifying if all the interfaces
listed in NETIFS are indeed available.

Extend lib.sh so that it's able to parse driver/net/net.config and
environment variables such as NETIF, REMOTE_TYPE, LOCAL_V4 etc described
in drivers/net/README.rst.
In order to make the transition towards running with a single local
interface smoother for the bash networking driver tests, beside sourcing
the net.config file also translate the new env variables into the old
style based on the NETIFS array. Since the NETIFS array only holds the
network interface names, also add a new array - TARGETS - which keeps
track of the target on which a specific interfaces resides - local,
netns or accesible through an ssh command.
For example, a net.config which looks like below:
NETIF=eth0
LOCAL_V4=192.168.1.1
REMOTE_V4=192.168.1.2
REMOTE_TYPE=ssh
REMOTE_ARGS=root@192.168.1.2
will generate the NETIFS and TARGETS arrays with the following data.
NETIFS[p1]="eth0"
NETIFS[p2]="eth2"
TARGETS[eth0]="local:"
TARGETS[eth2]="ssh:root@192.168.1.2"
The above will be true if on the remote target, the interface which has
the 192.168.1.2 address is named eth2.
Since the TARGETS array is indexed by the network interface name,
document a new restriction README.rst which states that the remote
interface cannot have the same name as the local one. Keep the old way
of populating the NETIFS variable based on the command line arguments.
This will be invoked in case DRIVER_TEST_CONFORMANT = "no".
Also add a couple of helpers which can be used by tests which need to
run a specific bash command on a different target than the local system,
be it either another netns or a remote system accessible through ssh.
The __run_on() function is passed through $1 the target on which the
command should be executed while run_on() is passed the name of the
interface that is then used to retrieve the target from the TARGETS
array.
Also add a stub run_on() function in net/lib.sh so that users of the
net/lib.sh are going through the stub only since neither NETIFS nor
TARGETS are valid in that circumstance.

Even though pause frame statistics are not exported through the same
ethtool command, there is no point in adding another helper just for
them. Extent the ethtool_std_stats_get() function so that we are able to
interrogate using the same helper all the standard statistics.
And since we are touching the function, convert the initial ethtool call
as well to the jq --arg form in order to be easier to read.

All six PTP-over-IP test frames (3x IPv4 + 3x IPv6) contain incorrect
UDP checksums. The stored values are the ones-complement sums of just
the pseudo-headers, not the complete UDP checksums over pseudo-header +
UDP header + payload. This is characteristic of frames captured on the
sender before TX checksum offload completion.
For example, the IPv4 Sync and Follow-Up frames both store checksum
0xa3c8 despite having different UDP payloads and port numbers - 0xa3c8
is their shared pseudo-header sum (same src/dst IP, same protocol and
UDP length).
While most L2 switches forward frames without verifying transport
checksums, hardware that performs deep packet inspection or has PTP
awareness may validate UDP checksums and drop frames that fail
verification. This causes the 1588v2 over IPv4/IPv6 tests to fail on
such hardware even though L2 PTP (which has no UDP checksum) passes
fine.
Replace all six pseudo-header partial sums with the correctly computed
full UDP checksums:
IPv4 Sync: 0xa3c8 -> 0x9f41
IPv4 Follow-Up: 0xa3c8 -> 0xeb8a
IPv4 Peer Delay Req: 0xa2bc -> 0x9ab9
IPv6 Sync: 0x2e92 -> 0x1476
IPv6 Follow-Up: 0x2e92 -> 0xf047
IPv6 Peer Delay Req: 0xb454 -> 0x891f

Add tests to local_termination.sh to verify that link-local frames
arrive. On some switches the DSA driver uses bridges to connect the
user ports to their CPU ports. More "intelligent" switches typically
don't forward link-local frames, but may trap them to an internal
microcontroller. The driver may have to change trapping rules, so
link-local frames end up on the DSA CPU ports instead of being
silently dropped or trapped to the internal microcontroller of the
switch.
Add two tests which help to validate this has been done correctly:
- Link-local STP BPDU should arrive at the Linux netdev when the
bridge has STP disabled (BR_NO_STP), in which case the bridge
forwards them rather than consuming them in the control plane
- Link-local LLDP should arrive at standalone ports (and the test
should be skipped on bridged ports similar to how it is done
for the IEEE1588v2/PTP tests)

Several forwarding tests (e.g., gre_multipath.sh) initialize both IPv4
and IPv6 addresses using simple_if_init, but only clean up IPv4
in simple_if_fini. This leaves stale IPv6 addresses on the interfaces,
which causes subsequent tests to fail when they encounter unexpected
address configuration.
The issue can be reproduced by running tests in sequence:
# run_kselftest.sh -t net/forwarding:ipip_hier_gre.sh
# run_kselftest.sh -t net/forwarding:min_max_mtu.sh
TAP version 13
1..1
# timeout set to 0
# selftests: net/forwarding: min_max_mtu.sh
# TEST: ping [ OK ]
# TEST: ping6 [ OK ]
# TEST: Test maximum MTU configuration [ OK ]
# TEST: Test traffic, packet size is maximum MTU [FAIL]
# Ping6, packet size: 65487 succeeded, but should have failed
# TEST: Test minimum MTU configuration [ OK ]
# TEST: Test traffic, packet size is minimum MTU [ OK ]
not ok 1 selftests: net/forwarding: min_max_mtu.sh # exit=1
Fix this by removing the unused IPv6 argument from simple_if_init in
tests that don't use IPv6 (gre_multipath.sh, ipip_lib.sh), and by
adding the missing IPv6 argument to simple_if_fini in tests that
use IPv6 (gre_multipath_nh.sh, gre_multipath_nh_res.sh).

Since we started running selftests in NIPA we have been seeing
tc_actions.sh generate a soft lockup warning on ~20% of the runs.
On the pre-netdev foundation setup it was actually a missed irq
splat from the console. Now it's either that or a lockup.
I initially suspected a socket locking issue since the test
is exercising local loopback with act_mirred.
After hours of staring at this I noticed in strace that ncat
when -o $file is specified _both_ saves the output to the file
and still prints it to stdout. Because the file being sent
is constructed with:
dd conv=sparse status=none if=/dev/zero bs=1M count=2 of=$mirred
^^^^^^^^^
the data printed is all \0. Most terminals don't display nul
characters (and neither does vng output capture save them).
But QEMU's serial console still has to poke them thru which
is very slow and causes the lockup (if the file is >600kB).
Replace the '-o $file' with '> $file'. This speeds the test up
from 2m20s to 18s on debug kernels, and prevents the warnings.

The tests use the tc pedit action to modify the IPv4 source address
("pedit ex munge ip src set"), but the IP header checksum is not
recalculated after the modification. As a result, the modified packet
fails sanity checks in br_netfilter after bridging and is dropped,
which causes the test to fail.
Fix this by ensuring net.bridge.bridge-nf-call-iptables is set to 0
during the test execution. This prevents the bridge from passing
L2 traffic to netfilter, bypassing the checksum validation that
causes the test failure.

This test runs an overlay traffic, forwarded over a multicast-routed VXLAN
underlay. In order to determine whether packets reach their intended
destination, it uses a TC match. For convenience, it uses a flower match,
which however does not allow matching on the encapsulated packet. So
various service traffic ends up being indistinguishable from the test
packets, and ends up confusing the test. To alleviate the problem, the test
uses sleep to allow the necessary service traffic to run and clear the
channel, before running the test traffic. This worked for a while, but
lately we have nevertheless seen flakiness of the test in the CI.
Fix the issue by using u32 to match the encapsulated packet as well. The
confusing packets seem to always be IPv6 multicast listener reports.
Realistically they could be ARP or other ICMP6 traffic as well. Therefore
look for ethertype IPv4 in the IPv4 traffic test, and for IPv6 / UDP
combination in the IPv6 traffic test.

ret_set_ksft_status() calls ksft_status_merge() with the current return
status and the last one. It treats a non-zero return code from
ksft_status_merge() as an indication that the return status was
overwritten by the last one and therefore overwrites the return message
with the last one.
Currently, ksft_status_merge() returns a non-zero return code even if
the current return status and the last one are equal. This results in
return messages being overwritten which is counter-productive since we
are more interested in the first failure message and not the last one.
Fix by changing ksft_status_merge() to only return a non-zero return
code if the current return status was actually changed.
Add a test case which checks that the first error message is not
overwritten.

It seems that most of the tests prepare the interfaces once before the test
run (setup_prepare()), rely on setup_wait() to wait for link and only then
run the test(s).
local_termination brings the physical interfaces down and up during test
run but never wait for them to come up. If the auto-negotiation takes
some seconds, first test packets are being lost, which leads to
false-negative test results.
Use setup_wait() in run_test() to make sure auto-negotiation has been
completed after all simple_if_init() calls on physical interfaces and test
packets will not be lost because of the race against link establishment.

Most forwarding tests invoke forwarding_enable() to enable the router and
forwarding_restore() to restore the original configuration. Add a helper,
adf_forwarding_enable(), which is like forwarding_enable(), but takes care
of scheduling the cleanup automatically.
Convert the tests that currently use defer to schedule the cleanup.

Quoted from musl wiki:
GNU getopt permutes argv to pull options to the front, ahead of
non-option arguments. musl and the POSIX standard getopt stop
processing options at the first non-option argument with no
permutation.
Thus these scripts stop working on musl since non-option arguments for
tools using getopt() (in this case, (ar)ping) do not always come last.
Fix it by reordering arguments.

Add comprehensive selftest to verify:
- Per-port actor priority setting via ad_actor_port_prio
- Aggregator selection behavior with port_priority ad_select policy
Also move cmd_jq helper from forwarding/lib.sh to net/lib.sh for
broader reusability across network selftests.
Here is the result output
# ./bond_lacp_prio.sh
TEST: bond 802.3ad (ad_actor_port_prio setting) [ OK ]
TEST: bond 802.3ad (ad_actor_port_prio select) [ OK ]

setup_wait() takes an optional argument and then is called from the top
level of the test script. That confuses shellcheck, which thinks that maybe
the intention is to pass $1 of the script to the function, which is never
the case. To avoid having to annotate every single new test with a SC
disable, split the function in two: one that takes a mandatory argument,
and one that takes no argument at all.
Convert the two existing users of that optional argument, both in Spectrum
resource selftest, to use the new form. Clean up vxlan_bridge_1q_mc_ul.sh
to not pass a now-unused argument.

Tests may wish to add other interfaces to listen on. Notably locally
generated traffic uses dummy interfaces. The multicast daemon needs to know
about these so that it allows forming rules that involve these interfaces,
and so that net.ipv4.conf.X.mc_forwarding is set for the interfaces.
To that end, allow passing in a list of interfaces to configure in addition
to all the physical ones.
