The problem is that the recv buffer ends up w= ith sb_ccc > sb_hiwat, and the last recv from the test does not consume enough bytes to bring sb_ccc below hiwat, so nl_process_received_one() does not process anything in the snd buffer. I'm not sure if it's a kernel bug or not. The test could just read from the socket until FIONREAD reports that the number of available bytes is small enough, but I have no idea how this stuff is supposed to work. It would be nice to fix this though.. --=20 You are receiving this mail because: You are on the CC list for the bug.=
