* Add some utility transport functions in circuitbuild.[ch] so that we
can use them from pt.c.
* Make the accounting system consider traffic coming from proxies.
* Make sure that we only fetch bridge descriptors when all the
transports are configured.
* Create a function that will get input from a stream, so that we can
communicate with the managed proxy.
* Hackish change to tor_spawn_background() so that we can specify an
environ for our spawn.
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.
- const-ify some transport_t pointers
- Remove a vestigial argument to parse_bridge_line
- Make it compile without warnings on my laptop with
--enable-gcc-warnings
Multiple Bridge lines can point to the same one ClientTransportPlugin
line, and we can have multiple ClientTransportPlugin lines in our
configuration file that don't match with a bridge. We also issue a
warning when we have a Bridge line with a pluggable transport but we
can't match it to a ClientTransportPlugin line.
* Renamed transport_info_t to transport_t.
* Introduced transport_get_by_name().
* Killed match_bridges_with_transports().
We currently *don't* detect whether any bridges miss their transports,
of if any transports miss their bridges.
* Various code and aesthetic tweaks and English language changes.
* Improved function documentation.
* Renamed find_bridge_transport_by_addrport() to
find_transport_by_bridge_addrport().
* Sanitized log severities we use.
* Ran check-spaces.
When we set a networkstatus in the non-preferred flavor, we'd check
the time in the current_consensus. But that might have been NULL,
which could produce a crash as seen in bug 3361.
George Kadianakis notes that if you give crypto_rand_int() a value
above INT_MAX, it can return a negative number, which is not what
the documentation would imply.
The simple solution is to assert that the input is in [1,INT_MAX+1].
If in the future we need a random-value function that can return
values up to UINT_MAX, we can add one.
Fixes bug 3306; bugfix on 0.2.2pre14.
When we added the check for key size, we required that the keys be
128 bytes. But RSA_size (which defers to BN_num_bytes) will return
128 for keys of length 1017..1024. This patch adds a new
crypto_pk_num_bits() that returns the actual number of significant
bits in the modulus, and uses that to enforce key sizes.
Also, credit the original bug3318 in the changes file.
