           Summary: sshd does not forward break request to process as
                    SIGINT
           Product: Portable OpenSSH
           Version: 5.8p1
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: sshd
        AssignedTo: unassigned-bugs@mindrot.org
        ReportedBy: david.choweller@pb.com


Older implementations of sshd forwarded a break request to the
connected process as a SIGINT.  This was fixed (see bug 888), but seems
to have re-appeared again.

We see the following in the syslog:


Feb 15 12:51:24 jerom sshd[14392]: debug1: server_input_channel_req:
channel 0 request break reply 0
Feb 15 12:51:24 jerom sshd[14392]: debug1: session_by_channel: session
0 channel 0
Feb 15 12:51:24 jerom sshd[14392]: debug1: session_input_channel_req:
session 0 req break


However, the connected process is not getting a SIGINT.
