Hi Neal,
Apologies for the delay, and happy new year!
To answer your question, data is only transferred in one direction
(from the client to the server). The SeqNo in the pkts from the server
to the client is not incremented. So I don't think that a data pkt is
attempted to be sent in the tcp_dat
Hi,
while working on Debian bug [1] and the Ubuntu counterpart of it
I found that the tests can throw a broken pipe warning.
I kept the associated check-and-retry of the length separate to
discuss the changes individually - feel free to squash them on
commit if preferred.
[1]: https://bugs.debian
The change to limit the read size from /dev/urandom is a tradeoff.
Reading too much can trigger an issue, but so it could if the
suggested 250 random chars would not contain enough [:alpha:] chars.
If they contain:
a) >=6 all is ok
b) [1-5] the devname would be shorter than expected (non fatal).

In some test environments like e.g. Ubuntu & Debian autopkgtest it
can happen that while generating random device names the pipes
between tr and head are considered dead while processing.
That prints (non fatal) issues like:
