[Bug 1801128] Re: OpenSSH 7.7 -w tunnel bug

Debian has 7.9p1, so as soon as Disco opens up for development the next
sync will get the fix there.

Title:
  OpenSSH 7.7 -w tunnel bug

Status in openssh package in Ubuntu:
  New
Status in openssh source package in Cosmic:
  New

Bug description:
  Just upgraded to cosmic, which picks up OpenSSH 7.7.

  OpenSSH 7.7 has known bug
  https://bugzilla.mindrot.org/show_bug.cgi?id=2855 which is fixed in
  OpenSSH 7.8.  It's a regression that completely breaks -w tunneling.

  The OpenSSH bug contains a trivial two-line patch to fix the bug.  I
  downloaded the Ubuntu openssh package source, applied the patch and
  rebuilt, and can confirm that is does fix the problem.

  Any chance we could get this patch backported to Cosmic?
