My current thinking is that the problem might be related to using KTLS in a situation, where the TCP sends a FIN, but still has outstanding data. KTLS = is tested a lot with the RACK stack, which does NOT send a FIN if there is outstanding data. This could be the problem with len =3D 1, since the FIN t= akes conceptually one byte in the sequence number space, but there is no corresponding byte in the data stream... --=20 You are receiving this mail because: You are the assignee for the bug.
