Yay, family key's are live:
Implemented-In: Tor 0.4.9.1-alpha
Note that the version number given there is wrong.
tor 0.4.9.1-alpha does not include support for the new happy families feature.
0.4.9.2-alpha will probably be the first tor release with happy families
support.
This has been corrected on this page:
https://community.torproject.org/relay/setup/post-install/family-ids/
but has not found its way to the proposal page yet.
Thanks to early adopters like toralf bugs in happy families are being reported
and fixed.
I really hope I don't have to copy paste it all given the amount of relays
that I am currently running. Hopefully, nusenu will update the ansible repo
to support it.
:-)
Nusenu has not only implemented this in his ansible-relayor, but has also
given hints during development:
https://gitlab.torproject.org/tpo/core/tor/-/merge_requests/857#note_3164207
The current implementation in tor does not support setting the path to the
family key file.
Which is a bit cumbersome for large operators because they need to copy the file
for every tor instance (keys folder) instead of a single time for each server
and a single torrc config line.
This is less problematic for ansible-relayor than for operators doing it
manually because we can automate that
task in realyor, but the runtime will certainly increase significantly for
large operators if we need to copy that file for every tor instance including
setting permissions and so on.
I hope a torrc option for specifying the path to the key file is added before
the first tor release with happy families is published
to mitigate this overhead.
Here is the related gitlab issue for it:
https://gitlab.torproject.org/tpo/core/tor/-/issues/41033
After this has been clarified/implemented (or rejected) an ansible-relayor
release with happy families support will be implemented.
OrNetStats will also get Happy Families support but this depends on onionoo's
support for Happy Families:
https://gitlab.torproject.org/tpo/network-health/metrics/onionoo/-/issues/40051
I found it surprising to learn from the proposal that the old MyFamily design
makes up over 80% of microdescriptors size
so this change has significant potential to decrease the bandwidth used for
answering directory requests
https://metrics.torproject.org/dirbytes.html
but since both Family designs will co-exist for some time for backward
compatibility reasons it will take some time before operators can remove there
old
MyFamily lines from their torrc config files.
kind regards,
nusenu
