[PATCH 1/3] selftests/net: Argument value mismatch when calling verify_counters()
Posted by Dmitry Safonov 1 year, 11 months ago
From: Mohammad Nassiri <mnassiri@ciena.com>

The end_server() function only operates in the server thread
and always takes an accept socket instead of a listen socket as
its input argument. To align with this, invert the boolean values
used when calling verify_counters() within the end_server() function.

Fixes: 3c3ead555648 ("selftests/net: Add TCP-AO key-management test")

Hi Dmitry,

I see that this is correct, but I am wondering
if it fixes a user-visible bug. If so, could
some text about that go here?

Yep. The test as the result doesn't correctly check tcp counters for
non-symmetrical scenario, where peer-A uses a key <a:a2> to send data,
but peer-B uses <b:b2> key to send its data. So, in simple terms,
different keys for TX and RX on peers.

I'll send v2 with an improved patch message.
