           Summary: permanently_set_uid() doesn't work on BSDI 4.0.1
           Product: Portable OpenSSH
           Version: 3.7p1
          Platform: ix86
        OS/Version: BSDI
            Status: NEW
          Severity: normal
          Priority: P2
         Component: sshd
        AssignedTo: openssh-bugs at mindrot.org
        ReportedBy: jsr at dexter.mi.org


On BSDI 4.0.1, sshd answers the port but closes the connection before
negotiation is complete.  Replacing the permanently_set_uid() function in
uidswap.c with the one from 3.6.1p2 fixed the problem for BSDI.
