openssh bugs - Feb 2011 - [Bug 1859] New: sshd does not forward break request to process as SIGINT

https://bugzilla.mindrot.org/show_bug.cgi?id=1859

           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 at mindrot.org
        ReportedBy: david.choweller at 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.

send break to correct fd

Break delivery in sshd was indeed broken. This patch should fix it, but
I don't personally see any change in behaviour after applying it. Does
it help your case?
