It appears that things got a bit confused in the BV-01 case. In the BV-02
case, the stack tossed the extra byte and reported the error to stderror bu=
t
not to the application. To pass the test the application must be told that
there was an error reading the data (my interpretation of the test case is
that the stack can still send the application the data, but it must be
flagged as a failure). In both cases, the second packet should be correctly
received. It's not clear to me from the test case that receiving the second
packet correctly is mandatory, but it might be. It shouldn't be a problem t=
o
receive it correctly.

Below are the two scenarios:

BV-01 case:
