Return early when there is no suitable IPv6 ORPort.
Show the address and port on error, using a convenience function.
Code simplification and refactoring.
Cleanup after 32588.
When IPv6 ORPorts are set to "auto", tor relays and bridges would
advertise an incorrect port in their descriptor.
This may be a low-severity memory safety issue, because the published
port number may be derived from uninitialised or out-of-bounds memory
reads.
Fixes bug 32588; bugfix on 0.2.3.9-alpha.
This patch ensures that we always lowercase the BridgeDistribution from
torrc in descriptors before submitting it.
See: https://bugs.torproject.org/32753
Our dimap code asserts if you try to add the same key twice; this
can't happen if everything is running smoothly, but it's possible if
you try to start a relay where secret_onion_key_ntor is the same as
secret_onion_key_ntor.old.
Fixes bug 30916; bugfix on 0.2.4.8-alpha when ntor keys were
introduced.
Always publish bridge pluggable transport information in the extra info
descriptor, even if ExtraInfoStatistics is 0. This information is
needed by BridgeDB.
Fixes bug 30956; bugfix on 0.4.1.1-alpha.
Previously we purged it in 1-hour increments -- but one-hour is the
maximum TTL for the cache! Now we do it in 25%-TTL increments.
Fixes bug 29617; bugfix on 0.3.5.1-alpha.
I don't believe any of these represent a real timing vulnerability
(remote timing against memcmp() on a modern CPU is not easy), but
these are the ones where I believe we should be more careful.
This should please coverity, and fix CID 1415721. It didn't
understand that networkstatus_get_param() always returns a value
between its minimum and maximum values.
... and ed25519_public_to_base64(). Also remove all checks for the return
values, which were redundant anyway, because the functions never failed.
Part of 29960.
Remove router_update_info_send_unencrypted(), and move its code into the
relevant functions.
Then, re-use an options pointer.
Preparation for testing 29017 and 20918.
Remove some tiny static functions called by router_build_fresh_descriptor(),
and move their code into more relevant functions.
Then, give router_update_{router,extra}info_descriptor_body identical layouts.
Preparation for testing 29017 and 20918.
Make sure that these static functions aren't passed NULL.
If they are, log a BUG() warning, and return an error.
Preparation for testing 29017 and 20918.
