The amt.sh requires smcrouted for multicasting routing.
So, it starts smcrouted before forwarding tests.
It must be stopped after all tests, but it isn't.
To fix this issue, it kills smcrouted in the cleanup logic.

When running the bridge IGMP/MLD selftests on debug kernels we can get
spurious errors when setting up the IGMP/MLD exclude timeout tests
because the membership interval is just 3 seconds and the setup has 2
seconds of sleep plus various validations, the one second that is left
is not enough. Increase the membership interval from 3 to 5 seconds to

There are multiple versions of nc out there, switch

Tell socat to exit after 128 bytes and pad the message.

moving over the test and just setting non-zero exit code
with no output indicating what failed.

Align the behavior for gcc and clang builds by interpreting unset
`ARCH` and `CROSS_COMPILE` variables in `LLVM` builds as a sign that the
user wants to build for the host architecture.
This patch preserves the properties that setting the `ARCH` variable to an
unknown value will trigger an error that complains about insufficient
information, and that a set `CROSS_COMPILE` variable will override the
target triple that is determined based on presence/absence of `ARCH`.
When compiling with clang, i.e., `LLVM` is set, an unset `ARCH` variable in
combination with an unset `CROSS_COMPILE` variable, i.e., compiling for
the host architecture, leads to compilation failures since `lib.mk` can
not determine the clang target triple. In this case, the following error
message is displayed for each subsystem that does not set `ARCH` in its
own Makefile before including `lib.mk` (lines wrapped at 75 chrs):
make[1]: Entering directory '/mnt/build/linux/tools/testing/selftests/
sysctl'
../lib.mk:33: *** Specify CROSS_COMPILE or add '--target=' option to
lib.mk. Stop.
make[1]: Leaving directory '/mnt/build/linux/tools/testing/selftests/
sysctl'
In the same scenario a gcc build would default to the host architecture,
i.e., it would use plain `gcc`.

While trying to fix this, I noticed that:
a) selftests/lib.mk already avoids the problem, and
b) The binderfs Makefile indavertently bypasses the selftests/lib.mk
build system, and quitely uses Make's implicit build rules for .c files
instead.
The Makefile attempts to set up both a dependency and a source file,
neither of which was needed, because lib.mk is able to automatically
handle both. This line:
binderfs_test: binderfs_test.c
...causes Make's implicit rules to run, which builds binderfs_test
without ever looking at lib.mk.
Fix this by simply deleting the "binderfs_test:" Makefile target and
letting lib.mk handle it instead.

Current MPTCP servers increment MPTcpExtMPCapableFallbackACK when they
accept non-MPC connections. As reported by Christoph, this is "surprising"
because the counter might become greater than MPTcpExtMPCapableSYNRX.
MPTcpExtMPCapableFallbackACK counter's name suggests it should only be
incremented when a connection was seen using MPTCP options, then a
fallback to TCP has been done. Let's do that by incrementing it when
the subflow context of an inbound MPC connection attempt is dropped.
Also, update mptcp_connect.sh kselftest, to ensure that the
above MIB does not increment in case a pure TCP client connects to a
MPTCP server.
