02e2edeb33 prop224: Add hs_config.{c|h} with a refactoring
Add the hs_config.{c|h} files contains everything that the HS subsystem needs
to load and configure services. Ultimately, it should also contain client
functions such as client authorization.

This comes with a big refactoring of rend_config_services() which has now
changed to only configure a single service and it is stripped down of the
common directives which are now part of the generic handler.

This is ground work for prop224 of course but only touches version 2 services
and add XXX note for version 3.

config: Fix duplicate error message for nonlocal SocksPorts.
If `validate_only` is true, then just validate the configuration without warning
about it.  This way, we only emit warnings when the listener is actually opened.
(Otherwise, every time we parse the config we will might re-warn and we would
need to keep state; whereas the listeners are only opened once.)

b867295ffd config: Parse ports at the start of options_validate()
There was a bug that got exposed with the removal of ORListenAddress. Within
server_mode(), we now only check ORPort_set which is set in parse_ports().

However, options_validate() is using server_mode() at the start to check if we
need to look at the uname but then the ORPort_set is unset at that point
because the port parsing was done just after. This commit fixes that.

b0e92634d8 Netflow record collapsing defense.
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.

c2d1d949de Use tor_compress_supports_method() before printing library versions.
This patch ensures that Tor checks if a given compression method is
supported before printing the version string when calling `tor
--library-versions`.

Additionally, we use the `tor_compress_supports_method()` to check if a
given version is supported for Tor's start-up version string, but here
we print "N/A" if a given compression method is unavailable.

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
IP address when that limit was shared with an authority. Nowadays,
the idea is pretty obsolete.

Also remove the router_addr_is_trusted_dir() function, which served
no other purpose.

Closes ticket 20960.

f80a43d16f Stop ignoring hidden service key anonymity when first starting tor
Instead, refuse to start tor if any hidden service key has been used in
a different hidden service anonymity mode.

Fixes bug 20638; bugfix on 17178 in 0.2.9.3-alpha; reported by ahf.

The original single onion service poisoning code checked poisoning state
in options_validate, and poisoned in options_act. This was problematic,
because the global array of hidden services had not been populated in
options_validate (and there were ordrering issues with hidden service
directory creation).

This patch fixes this issue in rend_service_check_dir_and_add, which:
* creates the directory, or checks permissions on an existing directory, then
* checks the poisoning state of the directory, then
* poisons the directory.

When validating, only the permissions checks and the poisoning state checks
are perfomed (the directory is not modified).

This way, Authorities, Tor2web, and Single Onion Services don't write

Also reorder options validation so we modify UseEntryNodes first, then

b560f852f2 Implement Prop #260: Single Onion Services
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.

Implements proposal #260, completes ticket #17178. Patch by teor & asn.

squash! fixup! fixup! fixup! fixup! fixup! fixup! fixup! fixup! fixup! fixup! fixup! fixup! fixup! Implement Prop #260: Single Onion Services

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.

Rewrite the unit tests to match and be more comprehensive.
Adds a bonus unit test for rend_service_load_all_keys().

Count unix sockets when counting client listeners
Users can't run an anonymous client and non-anonymous single
onion service at the same time. We need to know whether we have
any client ports or sockets open to do this check.

When determining whether a client port (SOCKS, Trans, NATD, DNS)
is set, count unix sockets when counting client listeners. This
has no user-visible behaviour change, because these options are
set once and never read in the current tor codebase.

Don't count sockets when setting ControlPort_set, that's what
ControlSocket is for. (This will be reviewed in #19665.)

Don't count sockets when counting server listeners, because the code
that uses these options expects to count externally-visible ports.
(And it would change the behaviour of Tor.)

53a3b39da1 Add -Wmissing-variable-declarations, with attendant fixes
This is a big-ish patch, but it's very straightforward.  Under this
clang warning, we're not actually allowed to have a global variable
without a previous extern declaration for it.  The cases where we
violated this rule fall into three roughly equal groups:
  * Stuff that should have been static.
  * Stuff that was global but where the extern was local to some
    other C file.
  * Stuff that was only global when built for the unit tests, that
    needed a conditional extern in the headers.

The first two were IMO genuine problems; the last is a wart of how
we build tests.

But we have a huge pile of such comments accumulated for a large

So, here's what I tried to do:

  * 0.2.9 and 0.2.8 are retained, since those are not yet released.

  * XXX+ or XXX++ or XXX++++ or whatever means, "This one looks
    quite important!"

  * The others, after one-by-one examination, are downgraded to
    plain old XXX.  Which doesn't mean they aren't a problem -- just
    that they cannot possibly be a release-blocking problem.

368825ff45 Sandbox: Don't preseed getaddrinfo(gethostname()) in client mode.
If we're a server with no address configured, resolve_my_hostname
will need this.  But not otherwise.  And the preseeding itself can
consume a few seconds if like tails we have no resolvers.

Fixes bug 18548.

ef31c8862f Add changes file for 18448; refactor
(I've made it so FreeBSD || FreeBSD_kernel is enough to ensure that
we think you might have ipfw, and so that the logic is all in one
place.)

db263442af enable and test transproxy on FreeBSD derivatives #18448
The transproxy feature is only enabled when __FreeBSD__ is defined, and
only regular FreeBSD does that.  Change this to __FreeBSD_kernel__ which
is defined on derivatives as well.

This enables the relevant options/validate__transproxy test on FreeBSD
derivatives.

77a9de0d48 Automatically use IPv6 when ClientUseIPv4 is 0
Consequential changes to log messages:
  * it's no longer possible to disable both IPv4 and IPv6,
  * refactor common string out of remaining log messages

3b8216f215 Use fascist firewall and ClientUseIPv4 for bridge clients
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.

2d33d192fc Add ClientUseIPv4 and ClientPreferIPv6DirPort torrc options
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.
