[PATCH mptcp-next 1/4] selftests: mptcp: reset all the env vars

[Geliang Tang]

It's better to clear all the env vars in init_partial(), to let them be
reset before runing the next test.

[PATCH mptcp-next 2/4] selftests: mptcp: add fastclose env var

[Geliang Tang]

Use a new env var fastclose instead of passing fastclose to addr_nr_ns2.
It can be set with 'server' or 'client'. Then the fullmesh flag setting
code can be moved into pm_nl_set_endpoint() from do_transfer().

[PATCH mptcp-next 4/4] selftests: mptcp: add speed env var

[Geliang Tang]

Use a new env var speed instead of using 'speed' argument of run_tests()
and do_transfer(). It can be set with 'fast', 'slow', or the actual speed
number.

Thank you for looking at that!

I think it would be better to move the declaration of these variables to
do_transfer() (or run_tests()) instead of exporting them at the
beginning of the file, no?

You could do something like:

  local test_linkfail=${test_linkfail:-0}

So by default, it will have the value 0. But if you do

  tests_linkfail=3 \
      run_tests (...)

It will have the value 3 just for this test. WDYT?

It looks better than defining the variables globally and resetting them
elsewhere.

Cheers,
Matt

I forgot to say that apart from that (and it is also valid for the new
variables you add in the other patches and even FAILING_LINKS (and maybe
others)), the other modifications you did look good!

Hi Geliang,

Thank you for your modifications, that's great!

Our CI did some validations and here is its report:

If there are some issues, you can reproduce them using the same environment as
the one used by the CI thanks to a docker image, e.g.:

    $ cd [kernel source code]
    $ docker run -v "${PWD}:${PWD}:rw" -w "${PWD}" --privileged --rm -it \
        --pull always mptcp/mptcp-upstream-virtme-docker:latest \
        auto-debug

For more details:

    https://github.com/multipath-tcp/mptcp-upstream-virtme-docker


Please note that despite all the efforts that have been already done to have a
stable tests suite when executed on a public CI like here, it is possible some
reported issues are not due to your modifications. Still, do not hesitate to
help us improve that ;-)
