These changes should be in 2.1 too. Sigh. They should be checked more carefully than the changes in tty_subr.c. I'm not sure what happens in the PF_REMOTE case. cc can only be 0 in that case if the PF_REMOTE flag changed. If that can happen, then cc may be too large to fit in the canq and not everything is written. Brucehome | help
