The UDP reuseport conflict was a little bit tricky.

The net-next code, via bpf-next, extracted the reuseport handling
into a helper so that the BPF sk lookup code could invoke it.

At the same time, the logic for reuseport handling of unconnected
sockets changed via commit efc6b6f6c3113e8b203b9debfb72d81e0f3dcace
which changed the logic to carry on the reuseport result into the
rest of the lookup loop if we do not return immediately.

This requires moving the reuseport_has_conns() logic into the callers.

While we are here, get rid of inline directives as they do not belong
in foo.c files.

The other changes were cases of more straightforward overlapping
modifications.

1b6687e31a vrf: Handle CONFIG_SYSCTL not set
Randy reported compile failure when CONFIG_SYSCTL is not set/enabled:

ERROR: modpost: "sysctl_vals" [drivers/net/vrf.ko] undefined!

Fix by splitting out the sysctl init and cleanup into helpers that
can be set to do nothing when CONFIG_SYSCTL is disabled. In addition,
move vrf_strict_mode and vrf_strict_mode_change to above
vrf_shared_table_handler (code move only) and wrap all of it
in the ifdef CONFIG_SYSCTL.

Update the strict mode tests to check for the existence of the
/proc/sys entry.

34fe5a1cf9 ipv6: fib6_select_path can not use out path for nexthop objects
Brian reported a crash in IPv6 code when using rpfilter with a setup
running FRR and external nexthop objects. The root cause of the crash
is fib6_select_path setting fib6_nh in the result to NULL because of
an improper check for nexthop objects.

More specifically, rpfilter invokes ip6_route_lookup with flowi6_oif
set causing fib6_select_path to be called with have_oif_match set.
fib6_select_path has early check on have_oif_match and jumps to the
out label which presumes a builtin fib6_nh. This path is invalid for
nexthop objects; for external nexthops fib6_select_path needs to just
return if the fib6_nh has already been set in the result otherwise it
returns after the call to nexthop_path_fib6_result. Update the check
on have_oif_match to not bail on external nexthops.

Update selftests for this problem.

0b8241fe3c selftests: mptcp: capture pcap on both sides
When investigating performance issues that involve latency / loss /
reordering it is useful to have the pcap from the sender-side as it
allows to easier infer the state of the sender's congestion-control,
loss-recovery, etc.

Allow the selftests to capture a pcap on both sender and receiver so
that this information is not lost when reproducing.

This patch also improves the file names. Instead of:

  ns4-5ee79a56-X4O6gS-ns3-5ee79a56-X4O6gS-MPTCP-MPTCP-10.0.3.1.pcap

We now have something like for the same test:

  5ee79a56-X4O6gS-ns3-ns4-MPTCP-MPTCP-10.0.3.1-10030-connector.pcap
  5ee79a56-X4O6gS-ns3-ns4-MPTCP-MPTCP-10.0.3.1-10030-listener.pcap

It was a connection from ns3 to ns4, better to start with ns3 then. The
port is also added, easier to find the trace we want.

767659f650 selftests: mptcp: add option to specify size of file to transfer
The script generates two random files that are then sent via tcp and
mptcp connections.

In order to compare throughput over consecutive runs add an option
to provide the file size on the command line: "-f 128000".

Also add an option, -t, to enable tcp tests. This is useful to
compare throughput of mptcp connections and tcp connections.

Example: run tests with a 4mb file size, 300ms delay 0.01% loss,
default gso/tso/gro settings and with large write/blocking io:

mptcp_connect.sh -t -f $((4 * 1024 * 1024)) -d 300 -l 0.01%  -r 0 -e "" -m mmap

0558c39604 selftests/net: plug rxtimestamp test into kselftest framework
Run rxtimestamp as part of TEST_PROGS. Analogous to other tests, add
new rxtimestamp.sh wrapper script, so that the test runs isolated
from background traffic in a private network namespace.

Also ignore failures of test case #6 by default. This case verifies
that a receive timestamp is not reported if timestamp reporting is
enabled for a socket, but generation is disabled. Receive timestamp
generation has to be enabled globally, as no associated socket is
known yet. A background process that enables rx timestamp generation
therefore causes a false positive. Ntpd is one example that does.

Add a "--strict" option to cause failure in the event that any test
case fails, including test #6. This is useful for environments that
are known to not have such background processes.

Tested:
make -C tools/testing/selftests TARGETS="net" run_tests

0e6fbe39bd net/tls(TLS_SW): Add selftest for 'chunked' sendfile test
This selftest tests for cases where sendfile's 'count'
parameter is provided with a size greater than the intended
file size.

Motivation: When sendfile is provided with 'count' parameter
value that is greater than the size of the file, kTLS example
fails to send the file correctly. Last chunk of the file is
not sent, and the data integrity is compromised.
The reason is that the last chunk has MSG_MORE flag set
because of which it gets added to pending records, but is
not pushed.
Note that if user space were to send SSL_shutdown control
message, pending records would get flushed and the issue
would not happen. So a shutdown control message following
sendfile can mask the issue.

Using ping in tests is error-prone, because ping is too smart. On a
flaky system (notably in a simulator), when packets don't come quickly
enough, more pings are sent, and that throws off counters. Instead use
mausezahn to generate ICMP echo request packets. That allows us to
send them in quicker succession as well, because the reason the ping
was made slow in the first place was to make the tests work on

Add Nik's torture tests as a new set to stress the replace and cleanup
paths.

Torture test created by Nikolay Aleksandrov and then I adapted to
selftest and added IPv6 version.

5a1b72cebc net: add large ecmp group nexthop tests
Add a couple large ecmp group nexthop selftests to cover
the remnant fixed by d69100b8eee27c2d60ee52df76e0b80a8d492d34.

The tests create 100 x32 ecmp groups of ipv4 and ipv6 and then
dump them. On kernels without the fix, they will fail due
to data remnant during the dump.

eb682677f5 selftests: Drop 'pref medium' in route checks
The 'pref medium' attribute was moved in iproute2 to be near the prefix
which is where it applies versus after the last nexthop. The nexthop
tests were updated to drop the string from route checking, but it crept
in again with the compat tests.

We were lucky because recent additions added 'out' parameters,
still we need to clean our reference implementation, before folks
