openssh bugs - Dec 2011 - [Bug 1966] New: Copy DSCP field from request to response packets

https://bugzilla.mindrot.org/show_bug.cgi?id=1966

             Bug #: 1966
           Summary: Copy DSCP field from request to response packets
    Classification: Unclassified
           Product: Portable OpenSSH
           Version: 5.9p1
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: sshd
        AssignedTo: unassigned-bugs at mindrot.org
        ReportedBy: bugzilla.mindrot.org at pobox.madduck.net


sshd seems to ignore the DSCP field in packets sent by clients. I think
it would be sensible if it copied the DSCP field to its response
packets, though maybe it would make sense to be able to override this
in the configuration, e.g.

  IPQoSResponse nodelay throughput   (the default)
  IPQoSResponse copy throughput      (copy from client packet for
interactive sessions)
  ?

How would sshd find out the TOS/DSCP of the incoming packets? On most
platforms IP_TOS is write-only...
