[PATCH mptcp-net 4/4] selftests: mptcp: rm subflow with v4/v4mapped addr
Posted by Geliang Tang 7 months, 3 weeks ago 
From: Geliang Tang <tanggeliang@kylinos.cn>

Now both a v4 address and a v4-mapped address are supported when
destroying a userspace pm subflow, this patch adds random tests for both
addresses.

Closes: https://github.com/multipath-tcp/mptcp_net-next/issues/387
Fixes: 48d73f609dcc ("selftests: mptcp: update userspace pm addr tests")

Instead of randomizing this test, does it work to add a second subflow to 
this test case?

Then the two subflows could be removed two different ways (one with the 
v4mapped and one with v4)? That should avoid adding too much test time.

Yes, it works.

I just sent a v2 for this with only patch 3 and patch 4 in it.
