Keep-alive probes have seq number set to SND.NXT - 1 and may or may not contain an octet of data. The latter case was not handled properly therefore add a special case when validating seq number to response to keep-alive probes. Signed-off-by: Robert Lubos <[email protected]> (cherry picked from commit d93c5d6)
Add test verifying that if keep-alive messages are exchanged, the connection remains alive. Signed-off-by: Robert Lubos <[email protected]> (cherry picked from commit dcbd1ed)
