Have clients and authorities both have new behavior, since the
fix for bug 11243 has gone in. But make clients still accept
accept old bogus HSDir descriptors, to avoid fingerprinting trickery.
Fixes bug 9286.
If we're not a relay, we ignore it.
If it's set to 1, we obey ExitPolicy.
If it's set to 0, we force ExitPolicy to 'reject *:*'
And if it's set to auto, then we warn the user if they're running an
exit, and tell them how they can stop running an exit if they didn't
mean to do that.
Fixes ticket 10067
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.
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
When V3AuthVotingInterval is low, decrease the delay on the
If-Modified-Since header passed to directory servers.
This allows us to obtain consensuses promptly when the consensus
interval is very short.
This assists in bootstrapping a testing Tor network.
Fixes bugs 13718 & 13963.
Decrease minimum consensus interval to 10 seconds
when TestingTorNetwork is set. (Or 5 seconds for
the first consensus.)
Fix code that assumes larger interval values.
This assists in quickly bootstrapping a testing
Tor network.
Fixes bugs 13718 & 13823.
Stop requiring exits to have non-zero bandwithcapacity in a
TestingTorNetwork. Instead, when TestingMinExitFlagThreshold is 0,
ignore exit bandwidthcapacity.
This assists in bootstrapping a testing Tor network.
Fixes bugs 13718 & 13839.
Makes bug 13161's TestingDirAuthVoteExit non-essential.
Matthew's autoaddr code returned an undecorated address when trying to check
that the code didn't insert an undecorated one into the map.
This patch fixes this by actually storing the undecorated address in tmp
instead of buf as it was originally intended.

Document why we divide it by two.
Check for > 0 instead of nonzero for success, since that's what the
manpage says.
Allow watchdog timers greater than 1 second.
It work by notifying systemd on a regular basis. If
there is no notification, the daemon is restarted.
This requires a version newer than the 209 version
of systemd, as it is not supported before.
When receiving a trasnsparently proxied request with tor using iptables tor
dies because the appropriate getsockopt calls aren't enabled on the sandbox.
This patch fixes this by adding the two getsockopt calls used when doing
transparent proxying with tor to the sandbox for the getsockopt policy.

The original call to getsockopt to know the original address on transparently
proxyed sockets using REDIRECT in iptables failed with IPv6 addresses because
it assumed all sockets used IPv4.
This patch fixes this by using the appropriate options and adding the headers
containing the needed definitions for these.

This is a good idea in case the caller stupidly doesn't check the
return value from baseX_decode(), and as a workaround for the
current inconsistent API of base16_decode.
