[PATCH mptcp-next v4 0/6] run sched tests in a dedicated ns

[PATCH mptcp-next v4 0/6] run sched tests in a dedicated ns

[Geliang Tang]

v4:
 - patch #1 could be merged before "mptcp: refactor push_pending logic"
   as a single fix.
 - patch #2 should be merged between "selftests/bpf: Add mptcp sched
   structs" and "selftests/bpf: Add bpf_first scheduler".

v3:
 - add two helpers.
 - drop sched_cleanup().

Geliang Tang (6):
  selftests/bpf: use random netns name for mptcp
  selftests/bpf: add two mptcp netns helpers
  Squash to "selftests/bpf: Add bpf_first test"
  Squash to "selftests/bpf: Add bpf_bkup test"
  Squash to "selftests/bpf: Add bpf_rr test"
  Squash to "selftests/bpf: Add bpf_red test"

[PATCH mptcp-next v4 1/6] selftests/bpf: use random netns name for mptcp

[Geliang Tang]

Use rand() to generate a random netns name instead of using the fixed
name "mptcp_ns" for every test.

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 ;-)

Thank you for the new version and for the explanations!

I suggest to apply the first patch also between "selftests/bpf: Add
mptcp sched structs" and "selftests/bpf: Add bpf_first scheduler" as it
seems not needed before (see my comment on this patch).

Re: [PATCH mptcp-next v4 1/6] selftests/bpf: use random netns name for mptcp

If we add the "Fixes" tag, it somehow means the previous behaviour was
buggy. I agree that it is better to do what you did here just in case
the previous netns has not been removed when re-launching the same test
multiple time (what a CI would not do I guess) but I also see that most
(all?) other BPF tests creating netns' use a fixed name.

I hope you don't mind if I then remove this Fixes tag when applying the
patch.

While at it, I will also explain the reason why this patch is needed,
something like:

  By doing that, we can re-launch the test even if there was an issue
  removing the previous netns or if by accident, a netns with this
  generic name already existed on the system. Note that using a
  different name each will also help adding more subtests in future
  commits.

Cheers,
Matt

I suggest to add the reason behind this patch:

  These new helpers will be re-used in future other subtests.

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

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 ;-)
