Bug in openssh-6.4p1

[Reinig, Peter]

Hello Guys,

I found the following bug of openssh-6.4p1 using Solaris 10 in channels.c which results in scanning only AF_INET6 addresses for X11 forwarding. If the server has only AF_INET addresses, these are never tested and so X11 forwarding fails.

The following diff shows a possible fix:

user at server [openssh-6.4p1] diff -c channels.c*
*** channels.c  Mo Nov 18 14:36:51 2013
--- channels.c_orig     Mo Nov 18 14:36:24 2013

*** 3470,3476 ****
                                        close(socks[n]);
                                }
                                num_socks = 0;
!                               continue;
                        }
                        socks[num_socks++] = sock;
                        if (num_socks == NUM_SOCKS)
--- 3470,3476 ----
                                        close(socks[n]);
                                }
                                num_socks = 0;
!                               break;
                        }
                        socks[num_socks++] = sock;
                        if (num_socks == NUM_SOCKS)
