Ok, found the problem. When using the port transport, UML starts in.telnetd
which will wait for connections. The user has no possibility to specify the
command line used to start in.telnetd, so your answer, while leading to the
good road, is not applicable.
The connection is done in port_connection() inside
arch/um/drivers/port_user.c. The default options don't include IPV6 settings.
Probably, adding -6 to them will make it work (or anyway, the solution will
be based on this idea).
I.e., I guess, you must modify this:
char *argv[] = { "/usr/sbin/in.telnetd", "-L",
"/usr/lib/uml/port-helper", NULL };
to get this:
char *argv[] = { "/usr/sbin/in.telnetd", "-6", "-L",
"/usr/lib/uml/port-helper", NULL };
(even if it's passed to run_helper, the semantics for argv are the same ones
to call execve).
