The bug, to be precise, is that the user can specify any buffer size they want, but that size gets thrown out when some of the other parts of the TCP control block are computed. > As for access to people's whiteboards, well, mine is hanging on my wall and > changes all the time.

Dillon spipe/mss'', which is actually for a slightly different problem, which I'm not certain I agree is entirely a bug, but which is closely related to this one and began manifesting itself at about the same time. Usually the stuff on my whiteboard has little to do with what I'm actually working on right now, and more to do with longer-term concerns that I think I might forget if I don't write them down. The other ``public'' items up there right now are ``NFS packet stealing'' and ``KERNEL -> _KERNEL''. -GAWollman -- Garrett A.
