No behaviour change
This function is used twice. The code is simpler if we split
it up and inline it where it is used.
|
|
|
|
Previosuly, during bootstrap, we would continue to download
consensuses if we had a consensus, but didn't have the certificates
to validate it.

we should avoid launching a consensus fetch if we don't want one,
but if we do end up with an extra one, we should let the other checks
take care of it.
|
|
We'll back off from the request in connection_ap_handshake_attach_circuit,
or cancel it in connection_dir_close_consensus_fetches, and those are the
only places we need to check.

not once per second, and only do it when a consensus arrives

No behavioural change
This makes the use of the node explicit in the function, rather
than hiding the node lookup in fascist_firewall_allows_rs.

Variable rename only

This makes sure clients will only select relays which support
begindir over ORPort.
|
|
This improves client anonymity and avoids directory header tampering.
The extra load on the authorities should be offset by the fallback
directories feature.
This also simplifies the fixes to #18809.
|
|
Delete an unnecessary check for non-preferred IP versions.
Allows clients which can't reach any directories of their
preferred IP address version to get directory documents.
Patch on #17840 in 0.2.8.1-alpha.
|
|
|
|
After #17840 in 0.2.8.1-alpha, we incorrectly chose an IPv4
address for all DIRIND_ONEHOP directory connections,
even if the routerstatus didn't have an IPv4 address.
This likely affected bridge clients with IPv6 bridges.
Resolves #18921.

Also, document the actual behavior and return values of
tor_terminate_process.
Fixes bug18686; bugfix on 0.2.3.9-alpha.

The problem is that "q" is always set on the first iteration even
if the question is not a supported question. This set of "q" is
not necessary, and will be handled after exiting the loop if there
if a supported q->type was found.

* SHA-3/SHAKE use little endian for certain things, so byteswap as
needed.
* The code was written under the assumption that unaligned access to
quadwords is allowed, which isn't true particularly on non-Intel.

As well as the existing reports of IPv6 address additions or removals,
the script now warns when keys change but IPv4:ORPort or
IPv6:IPv6ORPort remain the same.
Existing checks for other whitelist detail changes have also
been re-worded and upgraded to warnings.
This makes it easier for changes to be identified so operators can
be contacted to confirm whether the change is stable.

Also add misbehaving relays to updateFallbackDirs.py blacklist,
but leave them commented out in case it's a transient issue,
or it's been resolved by the download check fixes. (These
relays hang stem's downloader. It's unlikely they'll ever help
clients.)
|
|
Use IP address, effective family, and contact info to
discover and limit fallbacks to one per operator.
Also analyse netblock, ports, IP version, and Exit flag,
and print the results. Don't exclude any fallbacks from
the list because of netblocks, ports, IP version, or
Exit flag.
|
|
When creating the list of fallbacks for a release:
* don't output fallback name and contact
* sort fallbacks by fingerprint
|
|
But as advertised bandwidth is controlled by relays,
use consensus weight and median weight to bandwidth ratio
to approximate measured bandwidth.
Includes minor comment changes and parameter reordering.
|
|
Previously, we would cut the list down to 100 fallbacks,
then check if they could serve a consensus, and comment
them out if they couldn't.
This would leave us with fewer than 100 active fallbacks.
Now, we stop when there are 100 active fallbacks.
Also count fallbacks with identical contact info.
Also fix minor logging issues.
|
|
Give each fallback a set weight of 10.0 for client selection.
Fallbacks must have at least 3000 consensus weight.
This is (nominally) 100 times the expected extra load of
20 kilobytes per second (50 GB per month).
Fixes issue #17905.
|
|
Improve the download test:
* Allow IPv4 DirPort checks to be turned off.
* Add a timeout to stem's consensus download.
* Actually check for download errors, rather than ignoring them.
* Simplify the timeout and download error checking logic.
Tweak whitelist/blacklist checks to be more robust.
Improve logging, make it warn by default.
Cleanse fallback comments more thoroughly:
* non-printables (yes, ContactInfo can have these)
* // comments (don't rely on newlines to prevent // */ escapes)

Fixes bug 18716; bugfix on 0.2.1.1-alpha where memarea.c was
introduced. Found by wbenny.
|
|
This changes simply renames them by removing "Testing" in front of them and
they do not require TestingTorNetwork to be enabled anymore.
Fixes #18481
