mesg Broke on Stable between 8/21 and 8/28

[Dave Tweten]

When I replaced a STABLE build from 8/21 with one from 8/29, "mesg" 
stopped working on xterms.

I treat each xterm as a login shell, and include "mesg n" in .login.  
The problem seems to be that ownership of /dev/ttyp? is not being 
transferred to the user anymore.  I remember that "options UCONSOLE" 
was involved in the transfer of ownership.  That configuration element 
was in both the 8/21 and 8/28 kernels; nothing was changed in the 
config file.

I checked the mailing list archives, and there does seem to be some 
recent action in the tty driver area.  Unfortunatly, we were 
compromised recently, and I'm only now getting my connections to e-mail 
lists (including this one) re-established, so my knowledge of recent 
list traffic is limited to what I can find on the web site.

Does anyone have any idea what has caused the change?
