[tor/master] relay: Remove possible ORPorts duplicate from parsed list
by nickm＠torproject.org 22 Jul '20

22 Jul '20

commit 803e769fb255f39dba07b5dbc2ca62a43b43004c Author: David Goulet <dgoulet(a)torproject.org> Date: Tue Jul 21 11:34:13 2020 -0400 relay: Remove possible ORPorts duplicate from parsed list Now that tor automatically binds to IPv4 _and_ IPv6, in order to avoid breaking configurations, we sanitize the parsed lists for duplicate ORPorts. It is possible to happen because we still allow this configuration; ORPort 9888 ORPort [4242::1]:9888 Meaning that the first ORPort value will bind to 0.0.0.0:9888 _and_ [::]:9888 which would lead to an error when attempting to bind on [4242::1]:9888. However, that configuration is accepted today and thus we must not break it. To remedy, we now sanitize the parsed list and prioritize an ORPort that has an explicit address over the global one. A warning is emitted if such configuration pattern is found. This is only for the ORPort.

[tor/master] relay: Change router_can_extend_over_ipv6() to look at configured port
by nickm＠torproject.org 22 Jul '20

22 Jul '20

commit 28c1b6047649dad62d269e6c2fde40f41cb9834a Author: David Goulet <dgoulet(a)torproject.org> Date: Tue Jul 21 13:11:28 2020 -0400 relay: Change router_can_extend_over_ipv6() to look at configured port In routerconf_find_ipv6_or_ap(), we check if the returned ORPort is internal but not for listening. This means that IPv6 [::] is considered internal. Thus, we can't use it, we have to look directly at the configured address and port and if they are valid, we do consider that we have a valid IPv6 ORPort and that we can thus extend in IPv6.

[tor/master] relay: Automatically Enable an IPv6 ORPort

commit c3a0f757964de0e8a24911d72abff5df20bb323c Author: David Goulet <dgoulet(a)torproject.org> Date: Tue Jul 21 09:28:52 2020 -0400 relay: Automatically Enable an IPv6 ORPort This commit makes it that if the ORPort is set with a single port, it will bind to both global listen IPv4 and IPv6 addresses. To pin an "ORPort <PORT>" to be IPv4 or IPv6, the IPv4Only/IPv6Only flags are honored thus this will _only_ bind on IPv6 for that port value: ORPort 9050 IPv6Only Results in: [::]:9050 ORPort 9051 IPv4Only Results in: [0.0.0.0]:9051 Attempting to configure an explicit IPv4 address with IPv6Only flag is an error and vice versa.
