Three tests share the initial namespace with the machine and fail on
what is already in it.
fdb_notify and test_vxlan_fdb_changelink bring up a vxlan device on the
default port 4789. Where the machine already has one there, and that
one is metadata based, as the device open vswitch keeps is, the port
cannot be shared and the test device is never created:
# ip link add vxs type vxlan external dstport 4789
# ip link add name vx up type vxlan id 2000 dstport 4789
RTNETLINK answers: Address already in use
# ./test_vxlan_fdb_changelink.sh
Cannot find device "vx"
expected two remotes after link set [FAIL]
Run both in a fresh namespace by re-executing them there, the way
nft_audit.sh, nft_concat_range.sh and br_netfilter_queue.sh already do.
bind_wildcard binds 0.0.0.0 and expects to know which sockets exist.
With 432 foreign sockets on 0.0.0.0 on the machine it failed 6 runs out
of 10; unsharing a namespace in FIXTURE_SETUP took that to 0 out of 10.
This is what commit a897e194c475 ("selftests: net: run reuseport in an
isolated netns") does for the reuseport tests.

Five cases report a failure where a feature is simply not there.
tls asks for every cipher it knows and fails on the ones the kernel does
not implement, SM4 and ARIA, which answer ENOENT at setsockopt
time. Skip a cipher the kernel refuses that way; the run then reports
632 passed, 264 skipped and none failed.
rtnetlink.sh sets up an erspan tunnel, which this kernel does not have
and which fails with "Unknown device type", and checks a netconf dump
whose exit status iproute2 gets wrong: 6.11 exits 2 on a dump that
worked, 6.17 exits 0. Probe for both and skip when unusable.
rtnetlink.py asks for an IPv4 multicast address dump the kernel answers
with EOPNOTSUPP, and ip_local_port_range asks for protocols it does not
have. Skip those too.

has the wrapper without the script it needs:

The script is listed in TEST_PROGS but, alone among the tests in that
directory, is not executable. The runner copes: it falls back to the
interpreter named in the shebang, so the test does run, and the only
trace is a line in the log
# Warning: file test_ingress_egress_chaining.sh is not executable

Bridged UDP tunnels such as VXLAN and GENEVE build an ICMP error packet
around an overlay packet if the packet is going to exceed the underlay
path MTU. The ICMP error packet is then injected back into the Rx path
with the source and destination addresses swapped, so that it will be
delivered to the overlay source.
If the overlay packet was routed to the UDP tunnel or locally generated,
then it is already carrying a valid dst entry and this entry is not
dropped when transforming the packet to an ICMP error packet. This
causes the IP layer to reuse the dst entry, leading to the ICMP error
packet being dropped or routed out of the UDP tunnel interface in case
of forwarding.
Prior to the blamed commit this could not happen, as
skb_tunnel_check_pmtu() did not build ICMP errors for PACKET_HOST
packets. Such packets were instead encapsulated and, unless the DF bit
was set in the outer header, fragmented by the underlay.
Fix this by making sure that the ICMP error packet does not have a valid
dst entry, thereby forcing the IP layer to perform a route lookup.
Adjust the bridged PMTU exception selftests accordingly. When the
local sender in ns_a pings the overlay destination with a deadline
(-w), ping exits on the first socket error before any reply is
received and returns a non-zero exit code. The test therefore only
passed because the ICMP error was never delivered. Use a packet count
(-c) like the ns_c line above it, so that the ICMP error counts
against the packet budget and the exit code depends on whether echo
replies were received. This passes with and without the fix.
Fixes: 8930424777e4 ("tunnels: Accept PACKET_HOST in skb_tunnel_check_pmtu().")
