openssh bugs - Feb 2006 - [Bug 1156] Closes connection after C-c is pressed on QNX

http://bugzilla.mindrot.org/show_bug.cgi?id=1156

           Summary: Closes connection after C-c is pressed on QNX
           Product: Portable OpenSSH
           Version: 4.3p2
          Platform: ix86
        OS/Version: other
            Status: NEW
          Severity: normal
          Priority: P2
         Component: sshd
        AssignedTo: bitbucket at mindrot.org
        ReportedBy: kraai at ftbfs.org


When I press Control-C while running a command (e.g., sleep 1) on QNX 6, after
the command finishes, the connection is closed:
> $ qnx18
> Welcome to QNX Neutrino!
> sh: j_init: tcgetpgrp() failed: Inappropriate I/O control operation
> sh: warning: won't have full job control
> Mon Feb 13 08:23:04 2006 on /dev/ttyp3
> Last login: Mon Feb 13 08:21:32 2006 on /dev/ttyp2
> $ sleep 1              # I pressed C-c here.
> Connection to qnx18 closed by remote host.
> Connection to qnx18 closed.
When I run sshd -d, pressing C-c kills sleep but does not cause the connection
to close.

I used the 20060213 snapshot.

Please try each of:
./configure --with-cflags=-DSSHD_ACQUIRES_CTTY
check_for_openpty_ctty_bug=1 ./configure

If it's the former, then see bug #245 for an explanation.

Created an attachment (id=1066)
 --> (http://bugzilla.mindrot.org/attachment.cgi?id=1066&action=view)
Define SSHD_ACQUIRES_CTTY on QNX

Defining SSHD_ACQUIRES_CTTY fixes the problem, so the attached patch makes
configure do so on QNX.
