Proposal 171 gives us a new syntax for parsing client port options.
You can now have as many FooPort options as you want (for Foo in
Socks, Trans, DNS, NATD), and they can have address:port arguments,
and you can specify the level of isolation on those ports.
Additionally, this patch refactors the client port parsing logic to
use a new type, port_cfg_t. Previously, ports to be bound were
half-parsed in config.c, and later re-parsed in connection.c when
we're about to bind them. Now, parsing a port means converting it
into a port_cfg_t, and binding it uses only a port_cfg_t, without
needing to parse the user-provided strings at all.
We should do a related refactoring on other port types. For
control ports, that'll be easy enough. For ORPort and DirPort,
we'll want to do this when we solve proposal 118 (letting servers
bind to and advertise multiple ports).
This implements tickets 3514 and 3515.
Returning a tristate is needless here; we can just use the yielded
transport/proxy_type field to tell whether there's a proxy, and have
the return indicate success/failure.
Also, store the proxy_type in the or_connection_t rather than letting
it get out of sync if a configuration reload happens between launching
the or_connection and deciding what to say with it.
This change also requires us to add and use a pair of
allocator/deallocator functions for socks_request_t, instead of
using tor_malloc_zero/tor_free directly.
In the code as it stood, we would accept any number of socks5
username/password authentication messages, regardless of whether we
had actually negotiated username/password authentication. Instead,
we should only accept one, and only if we have really negotiated
username/password authentication.
This patch also makes some fields of socks_request_t into uint8_t,
for safety.
* Improved function documentation.
* Renamed find_bridge_transport_by_addrport() to
find_transport_by_bridge_addrport().
* Sanitized log severities we use.
* Ran check-spaces.
UseBridges 1 now means "connect only to bridges; if you know no
bridges, don't make connections." UseBridges auto means "Use bridges
if they are known, and we have no EntryNodes set, and we aren't a
server." UseBridges 0 means "don't use bridges."
Fixes part of #1297; bugfix on 48e0228f1e,
when circuit_expire_building was changed to assume that timestamp_dirty
was set when a circuit changed purpose to _C_REND_READY. (It wasn't.)
On win64, sockets are of type UINT_PTR; on win32 they're u_int;
elsewhere they're int. The correct windows way to check a socket for
being set is to compare it with INVALID_SOCKET; elsewhere you see if
it is negative.
On Libevent 2, all callbacks take sockets as evutil_socket_t; we've
been passing them int.
This patch should fix compilation and correctness when built for
64-bit windows. Fixes bug 3270.
When running a system-wide instance of Tor on Unix-like systems, having
a ControlSocket is a quite handy mechanism to access Tor control
channel. But it would be easier if access to the Unix domain socket can
be granted by making control users members of the group running the Tor
process.
This change introduces a UnixSocketsGroupWritable option, which will
create Unix domain sockets (and thus ControlSocket) 'g+rw'. This allows
ControlSocket to offer same access control measures than
ControlPort+CookieAuthFileGroupReadable.

Previously, if they changed in torrc during a SIGHUP, all was well,
since we would just clear all transient entries from the addrmap
thanks to bug 1345. But if you changed them from the controller, Tor
would leave old mappings in place.
The VirtualAddrNetwork bug has been here since 0.1.1.19-rc; the
AutomapHosts* bug has been here since 0.2.0.1-alpha.
On IRC, wanoskarnet notes that if we ever do microdesc_free() on a
microdesc that's in the nodelist, we're in trouble. Also, we're in
trouble if we free one that's still in the microdesc_cache map.
This code adds a flag to microdesc_t to note where the microdesc is
referenced from, and checks those flags from microdesc_free(). I
don't believe we have any errors here now, but if we introduce some
later, let's log and recover from them rather than introducing
heisenbugs later on.
Addresses bug 3153.
Make that explicit by adding an assert and removing a null-check. All of
its callers currently depend on the argument being non-null anyway.
Silences a few clang complaints.
To turn this on, set UseMicrodescriptors to "1" (or "auto" if you
want it on-if-you're-a-client). It should go auto-by-default once
0.2.3.1-alpha is released.
Because of our node logic, directory caches will never use
microdescriptors when they have the right routerinfo available.
