In systemd 209, they deprecated -lsystemd-daemon in favor of
-lsystemd. So we'd better actually look at the pkg-config output,
or we'll get warnings on newer distributions.
For some as-yet-unknown-to-me reason, setting CFLAGS so early makes
it so -O2 -g doesn't get added to it later. So, adding it myself
later. Perhaps a better fix here can be found.
Fixes 14072; bugfix on 0.2.6.2-alpha. Based on a patch from h.venev
We had a check to block these, but the patch we merged as a1c1fc72
broke this check by making them absolute on demand every time we
opened them. That's not so great though. Instead, we should make them
absolute on startup, and not let them change after that.
Fixes bug 13397; bugfix on 0.2.3.11-alpha.
This happened because we changed AutomapHostsSuffixes to replace "."
with "", since a suffix of "" means "match everything." But our
option handling code for CSV options likes to remove empty entries
when it re-parses stuff.
Instead, let "." remain ".", and treat it specially when we're
checking for a match.
Fixes bug 12509; bugfix on 0.2.0.1-alpha.
This allows hidden services to disable the anti-scanning feature
introduced in 0.2.6.2-alpha. With this option not set, a connection
to an unlisted port closes the circuit. With this option set, only
a RELAY_DONE cell is sent.
Closes ticket #14084.
Supposedly there are a decent number of applications that "support"
IPv6 and SOCKS5 using the FQDN address type. While said applications
should be using the IPv6 address type, allow the connection if
SafeSocks is not set.
Bug not in any released version.
Stop assuming that private addresses are local when checking
reachability in a TestingTorNetwork. Instead, when testing, assume
all OR connections are remote. (This is necessary due to many test
scenarios running all nodes on localhost.)
This assists in bootstrapping a testing Tor network.
Fixes bugs 13718 & 13924.
If the consensus does not contain Exits, Tor will only build internal
circuits. In this case, relevant statuses will contain the word "internal"
as indicated in the Tor control-spec.txt. When bootstrap completes,
Tor will be ready to handle an application requesting an internal
circuit to hidden services at ".onion" addresses.
If a future consensus contains Exits, exit circuits may become available.
Tor already notifies the user at "notice" level if they have no exits in
the consensus, and can therefor only build internal paths.
Consequential change from #13718.
Tor can now build circuits from a consensus with no exits.
But if it tries to build exit circuits, they fail and flood the logs.
The circuit types in the Exit Circuits list below will only be
built if the current consensus has exits. If it doesn't,
only the Internal Circuits will be built. (This can change
with each new consensus.)
Fixes bug #13814, causes fewer path failures due to #13817.
Exit Circuits:
Predicted Exit Circuits
User Traffic Circuits
Most AP Streams
Circuits Marked Exit
Build Timeout Circuits (with exits)
Internal Circuits:
Hidden Service Server Circuits
Hidden Service Client Circuits
Hidden Service AP Streams
Hidden Service Intro Point Streams
Circuits Marked Internal
Build Timeout Circuits (with no exits)
Other Circuits?
If the consensus has no exits (typical of a bootstrapping
test network), allow tor to build circuits once enough
descriptors have been downloaded.
When there are no exits, we always have "enough"
exit descriptors. (We treat the proportion of available
exit descriptors as 100%.)
This assists in bootstrapping a testing Tor network.
Fixes bug 13718.
Makes bug 13161's TestingDirAuthVoteExit non-essential.
(But still useful for speeding up a bootstrap.)
Add router_have_consensus_path() which reports whether
the consensus has exit paths, internal paths, or whether it
just doesn't know.
Used by #13718 and #13814.
count_usable_descriptors now uses named exit_only values:
USABLE_DESCRIPTOR_ALL
USABLE_DESCRIPTOR_EXIT_ONLY
Add debug logging code for descriptor counts.
This (hopefully) resolves nickm's request in bug 13718 to improve
argument readability in nodelist.c.
choose_good_entry_server() now excludes current entry
guards and their families, unless we're in a test network,
and excluding guards would exclude all nodes.
This typically occurs in incredibly small tor networks,
and those using TestingAuthVoteGuard *
This is an incomplete fix, but is no worse than the previous
behaviour, and only applies to minimal, testing tor networks
(so it's no less secure).
Discovered as part of #13718.
Make hidden service port scanning harder by sending back REASON_DONE which
does not disclose that it was in fact an exit policy issue. After that, kill
the circuit immediately to avoid more bad requests on it.
This means that everytime an hidden service exit policy does match, the user
(malicious or not) needs to build a new circuit.
Fixes#13667.

Otherwise we risk a subsequent memdup or memcpy copying
uninitialized RAM into some other place that might eventually expose
it. Let's make sure that doesn't happen.
Closes ticket 14041
