RendPostPeriod only works on v2 onion services.
HiddenServiceAuthorizeClient is not yet implemented for v3 onion services.
Closes ticket #25661, bugfix on 0.3.2.1-alpha.
At this commit, the SocksSocketsGroupWritable option is renamed to
UnixSocksGroupWritable. A deprecated warning is triggered if the old option is
used and tor will use it properly.

Because this touches too many commits at once, it is made into one single
commit.
Remove the use of "tenths" for the circuit rate to simplify things. We can
only refill the buckets at best once every second because of the use of
approx_time() and our token system is set to be 1 token = 1 circuit so make
the rate a flat integer of circuit per second.

This makes clients on the public tor network prefer to bootstrap off fallback
directory mirrors.
This is a follow-up to 24679, which removed weights from the default fallbacks.
Implements ticket 24681.
This patch adds support for MainloopStats that allow developers to get
main event loop statistics via Tor's heartbeat status messages. The new
status log message will show how many succesful, erroneous, and idle
event loop iterations we have had.

This patch adds support for Android's logging subsystem in Tor. When
debugging Android applications it is useful to be able to collect
information about the application running on the platform via the
various system services that is available on the platform.
This patch allows you to add "Log notice android" to your torrc and have
Tor send everything above and including the notice severity to Android's
ring buffer which can be inspected using the 'adb logcat' program.

Few issues...
* Malformed ReducedExitPolicy, causing brackets to appear.
* ExitPolicyDefault wasn't actually listed, instead it munged the description
into the ExitPolicy description.
* Extra plus signs in the ExitPolicy and ReducedExitPolicy entries. After an
hour of struggling with asciidoc couldn't figure out how to format it as
'paragraph => example => paragraph with same indentation' so just
rearranging the ExitPolicy entry.
Patches welcome if someone strongly prefers having the paragraph after the
example.

(I was going to fix "along" to "along with" which was pretty clearly the
original intent, but then I realized that it would be confusing whether
it's only bad when you use several of them in conjunction, or what. So
hopefully this fix is clearer.)
Bridge relays can use it to add a "bridge-distribution-request" line
to their bridge descriptor, which tells BridgeDB how they'd like their
bridge address to be given out.
Implements tickets 18329.
But when clients are just starting, make them try each bridge a few times
before giving up on it.
These changes make the bridge download schedules more explicit: before
17750, they relied on undocumented behaviour and specific schedule
entries. (And between 17750 and this fix, they were broken.)
Fixes 23347, not in any released version of tor.
The download schedule tells Tor to wait 15 minutes before downloading
bridge descriptors. But 17750 made Tor ignore that and start immediately.
Since we fixed 17750, Tor waits 15 minutes for bridge client bootstrap,
like the schedule says.
This fixes the download schedule to start immediately, and to try each
bridge 3 times in the first 30 seconds. This should make bridge bootstraps
more reliable.
Fixes 23347.
Undeprecate it;
rename it to TestingClientDNSRejectInternalAddresses;
add the old name as an alias;

Closes tickets 21031 and 21522.
We removed this documentation in 607724c696, when we removed
Naming Authoritative Directories, but actually this file is still
used by authorities to indicate rejected and invalid fingerprints.
Closes ticket 21148.
Relay operators (especially bridge operators) can use this to lower
or raise the number of consensuses that they're willing to hold for
diff generation purposes.
This enables a workaround for bug 22883.
Move the HTTPProxy option to the deprecated list so for now it will only warn
users but feature is still in the code which will be removed in a future
stable version.

This unifies CircuitIdleTimeout and PredictedCircsRelevanceTime into a single
option, and randomizes it.
It also gives us control over the default value as well as relay-to-relay
connection lifespan through the consensus.

This defense will cause Cisco, Juniper, Fortinet, and other routers operating
in the default configuration to collapse netflow records that would normally
be split due to the 15 second flow idle timeout.
Collapsing these records should greatly reduce the utility of default netflow
data for correlation attacks, since all client-side records should become 30
minute chunks of total bytes sent/received, rather than creating multiple
separate records for every webpage load/ssh command interaction/XMPP chat/whatever
else happens to be inactive for more than 15 seconds.
The defense adds consensus parameters to govern the range of timeout values
for sending padding packets, as well as for keeping connections open.
The defense only sends padding when connections are otherwise inactive, and it
does not pad connections used solely for directory traffic at all. By default
it also doesn't pad inter-relay connections.
Statistics on the total padding in the last 24 hours are exported to the
extra-info descriptors.
Bridge lines in torrc can contain key=value settings as per-connection
arguments to a pluggable transport. tor.1.txt hadn't been updated to
reflect this.
In addition to the comments in the ticket, couple hidden service options have
been improved to clarify the maximum and minimum values they can be set to.

Back when Roger had do do most of our testing on the moria host, we
needed a higher limit for the number of relays running on a single

the idea is pretty obsolete.
Also remove the router_addr_is_trusted_dir() function, which served
no other purpose.
Closes ticket 20960.
If there is some horrible bug in our ed25519 link authentication
code that causes us to label every single ed25519-having node as
non-running, we'll be glad we had this. Otherwise we can remove it
later.
I need to be able to turn on Ed25519 support in client generation
of extend cells so I can test it, but leave it off-by-default until
enough clients support it for us to turn it on for a bunch at once.
This is part of #15056 / prop#220.
The client addr is essentially meaningless in this context (yes, it is
possible to explicitly `bind()` AF_LOCAL client side sockets to a path,
but no one does it, and there are better ways to grant that sort of
feature if people want it like using `SO_PASSCRED`).
Parse the value to UseEntryNodes_option, then set UseEntryNodes before
validating options.
This way, Authorities, Tor2web, and Single Onion Services don't write
spurious "UseEntryNodes 0" lines to their configs. Document the fact that
these tor configurations ignore UseEntryNodes in the manual page.
Also reorder options validation so we modify UseEntryNodes first, then
check its value against EntryNodes.
And silence a warning about disabled UseEntryNodes for hidden services
when we're actually in non-anonymous single onion service mode.
Add experimental OnionServiceSingleHopMode and
OnionServiceNonAnonymousMode options. When both are set to 1, every
hidden service on a tor instance becomes a non-anonymous Single Onion
Service. Single Onions make one-hop (direct) connections to their
introduction and renzedvous points. One-hop circuits make Single Onion
servers easily locatable, but clients remain location-anonymous.
This is compatible with the existing hidden service implementation, and
works on the current tor network without any changes to older relays or
clients.

Redesign single onion service poisoning.
When in OnionServiceSingleHopMode, each hidden service key is poisoned
(marked as non-anonymous) on creation by creating a poison file in the
hidden service directory.
Existing keys are considered non-anonymous if this file exists, and
anonymous if it does not.
Tor refuses to launch in OnionServiceSingleHopMode if any existing keys
are anonymous. Similarly, it refuses to launch in anonymous client mode
if any existing keys are non-anonymous.

Now, only advertised addresses are rejected by default by

ExitPolicyRejectLocalInterfaces is explicitly set to 1.

Regardless of the setting of ExtendAllowPrivateAddresses.
This fixes a bug with pluggable transports that ignore the
(potentially private) address in their bridge line.
Fixes bug 18517; bugfix on 23b088907f in tor-0.2.8.1-alpha.
When ClientPreferIPv6ORPort is auto, bridges prefer the configured
bridge ORPort address. Otherwise, they use the value of the option.
Other clients prefer IPv4 ORPorts if ClientPreferIPv6ORPort is auto.
When ClientPreferIPv6DirPort is auto, all clients prefer IPv4 DirPorts.
Bridge clients ignore ClientUseIPv6, acting as if it is always 1.
This preserves existing behaviour.
Make ClientPreferIPv6OR/DirPort auto by default:
* Bridge clients prefer IPv6 by default.
* Other clients prefer IPv4 by default.
This preserves existing behaviour.
ClientUseIPv4 0 tells tor to avoid IPv4 client connections.
ClientPreferIPv6DirPort 1 tells tor to prefer IPv6 directory connections.
Refactor policy for IPv4/IPv6 preferences.
Fix a bug where node->ipv6_preferred could become stale if
ClientPreferIPv6ORPort was changed after the consensus was loaded.
Update documentation, existing code, add unit tests.
This will give relay operators the ability of disabling the caching of
directory data. In general, this should not be necessary, but on some
lower-resource systems it may beneficial.
* The option is now KeepBindCapabilities
* We now warn if the user specifically asked for KeepBindCapabilities
and we can't deliver.
* The unit tests are willing to start.
* Fewer unused-variable warnings.
* More documentation, fewer misspellings.
Once tor is downloading a usable consensus, any other connection
attempts are not needed.

* fallback directories over authorities,
* connections initiated earlier over later connections
Close all other connections downloading a consensus.
Prop210: Add attempt-based connection schedules
Existing tor schedules increment the schedule position on failure,
then retry the connection after the scheduled time.
To make multiple simultaneous connections, we need to increment the
schedule position when making each attempt, then retry a (potentially
simultaneous) connection after the scheduled time.
(Also change find_dl_schedule_and_len to find_dl_schedule, as it no
longer takes or returns len.)
Prop210: Add multiple simultaneous consensus downloads for clients
Make connections on TestingClientBootstrapConsensus*DownloadSchedule,
incrementing the schedule each time the client attempts to connect.
Check if the number of downloads is less than
TestingClientBootstrapConsensusMaxInProgressTries before trying any
more connections.
UseDefaultFallbackDirs enables any hard-coded fallback
directory mirrors. Default is 1, set it to 0 to disable fallbacks.

However, this didn't change the option itself in tor (it's still SocksPort),
and wasn't even uniform in the man page. Functionally this doesn't matter
(tor's config options are case insensitive) but this is a pretty clear
regression.
