           Summary: OpenSSH 3.6.1p1 adding CRs, hurting CVS client/server
                    communications
           Product: Portable OpenSSH
           Version: 3.6.1p2
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: critical
          Priority: P2
         Component: ssh
        AssignedTo: openssh-bugs at mindrot.org
        ReportedBy: toscani at wideopenwest.com


Currently using OpenSSH under CygWin on an XP box to communicate with a CVS 
server on a Linux box.  Recently upgraded OpenSSH to v3.6.1p1 (the latest 
available under CygWin), and now CVS client/server communications don't
work.

I've tracked the problem to what I think (by process of elimination) is a 
new "feature" in OpenSSH whereby it converts LF to CR+LF line
terminators.
This pretty much hoses client/server communications, as the SSH server 
interprets all incoming lines as byte strings including a CR at the 
end...especially bad for pathname interpretation, but lots of other things may 
be affected as well.  I've tried altering the SSH server code to eat the
extra
CRs, but too many other things are broken (including file data exchange I'd 
bet...can't tell which CRs are valid and which are inserted by SSH) for that
to be effective.

i cannot reproduce this. i use cvs over openssh all
the time (since october 1999) and never see these problems.

if \r appears, then you probably allocate extra TTYs.

for ssh over cvs no TTYs should be allocated.
