Modified files:
sys/kern tty_pty.c
Log:
fix a few problems with pty. warn about how if you only have 1 pty
defined, your really getting 32. Also warn about how you can't have
more than 256 pty's when your using DEVFS (non DEVFS can use more, just
the makedev script doesn't know how to make >256). it also doesn't
allocate more memory than needed in this case.
Make sure that the signal passed in TIOCSIG isn't 0 as it might cause
a panic. I personally haven't seen this happen, but after a similar
bug in syscons crashed my machine, I'm acutely aware of this one. :)
