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.
This commit adds the src/trace directory containing the basics for our tracing
subsystem. It is not used in the code base. The "src/trace/debug.h" file
contains an example on how we can map our tor trace events to log_debug().
The tracing subsystem can only be enabled by tracing framework at compile
time. This commit introduces the "--enable-tracing-debug" option that will
make all "tor_trace()" function be maped to "log_debug()".

In an effort to better communicate with our users that they might need
to take certain actions when upgrading, we should extract from the
changelog the items that require some action (example: the new version
automatically generates keys, if you want them to be offline - make sure
to create them before upgrading).
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
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.
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.

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().

OnionTrafficOnly is equivalent to NoDNSRequest, NoIPv4Traffic,

Add unit tests for parsing and checking option validity.
Add documentation for each flag to the man page.
Add changes file for all of #18693.
Parsing only: the flags do not change client behaviour (yet!)
Rely on onion_populate_cpath to check that we're only using
TAP for the rare hidden service cases.
Check and log if handshakes only support TAP when they should support

From 0.2.7.2-alpha onwards, Exits would reject all the IP addresses
they knew about in their exit policy. But this may have disclosed
addresses that were otherwise unlisted.
Now, only advertised addresses are rejected by default by
ExitPolicyRejectPrivate. All known addresses are only rejected when
ExitPolicyRejectLocalInterfaces is explicitly set to 1.
Document this convention.
Add a script to post-process .gcov files in order to stop nagging us

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.
Fixes bug 17924; bugfix on 0.2.4.1-alpha.
In ddf5020ea8, we added config.log to CLEANFILES in doc/Makefile.am
so that distcheck would be happy about the presence of doc/config.log.
But when we moved to nonrecursie makefiles in 2a4a149624, we
accidentally left that filename unchanged, so that it referred to
config.log instead.
Patch from cypherpunks.
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.
