c50897c392 Put back the openpty(3) and ptsname(3) fixes but don't disable ptsname(3) 
on pts(4) devices this time.  This fixes the issues while leaving pts(4)
enabled on HEAD.

d3f576839b Back out last commit, since it accidentally broke pts. 
The security fix will be re-committed soon, hopefully without breaking
anything.

d32324f64f Clean up some of the pts(4) vs pty(4) stuff in grantpt(3) and friends: 
- Use PTY* for all pty(4) related constants.
- Use PTMX* for all pts(4) related constants.
- Consistently use _PATH_DEV PTMX rather than "/dev/ptmx".
- Revert 1.7 and properly fix it by using the correct prefix string for
  pts(4) masters.

ca81364fb1 Update posix_openpt(3) to handle 512 ptys. This was missed in the earlier 
pty(4) changes.

9b1fa2482e If the sysctl kern.pts.enable doesn't exist, check that /dev/ptmx is there, 
and if so, use the pts system.

67c7201e18 ptsname() bits for pts. 2006-01-26 01:33:55 +00:00

a617a18a23 Fix ptsname(3) by converting it to use devname(3) to obtain the name of 
a tty device instead of the legacy minor number approach.  This is known to
fix gnome-vfs' sftp module as well as kio_sftp and kdesu on -CURRENT.

Thanks to scottl for the snprintf() approach idea.

 o Remove unused variable: sbuf.
 o Don't use assignment as truth value.

d3951ad162 Implement POSIX grantpt(3) functionality, and add a pt_chown utility (akin 
to Solaris, it is in /usr/libexec) to perform the handing over of tty nodes
to the user being granted the pty.
