Comment:
I have pushed some extra tests and changes files:
* master: https://github.com/torproject/tor/pull/1874
This branch also fixes the following Rust protover bugs in master:
* #34248: add HSIntro=5 in Rust
* #34251: fix error handling in Rust protover is supported
I've left those tickets open, because we need to backport those changes.
Here are the features and functions that don't have unit tests:
* launch IPv6 ORPort self-test circuits
* fmt_addr32_port()
* fmt_af_family() - refactoring
* fmt_addr_family() - refactoring
* router_get_orport()
* extend_info_from_router()
* router_do_orport_reachability_checks()
* router_do_dirport_reachability_checks() - minor modifications and
refactoring
* router_do_reachability_checks() - minor modifications and refactoring
* inform_testing_reachability() - minor modifications and refactoring
* when launching IPv6 ORPort self-test circuits, make sure that the last
hop supports IPv6 extends
* node_supports_initiating_ipv6_extends()
* node_supports_accepting_ipv6_extends()
* router_add_running_nodes_to_smartlist() - added IPv6 extend check
These tests should be much easier to write on top of the refactor in
#34200.
This code runs in chutney's IPv6 networks, which are part of Tor's CI. But
chutney doesn't fully test IPv6 reachability yet. Chutney will test more
of this code, when we split tor's IPv4 and IPv6 reachability flags in
#34067.
