Arvid Norberg 7251575d98 This patch does: (#633)
1. simplifies and regularizies creation of listen sockets based on the listen
   interfaces setting.
2. simplifies and improves the behavior of UDP sockets, which are now explicitly
   opened per listen interface
3. transitions udp tracker, DHT and uTP socket manager over to using the new
   udp sockets
4. greatly simplified udp_socket to only wrap a single underlying socket (as
   opposed to one IPv4 and IPv6 socket)
5. improved behavior of bind-to-device
6. introduce an array_view type to make udp packet passing code simpler
7. simplify and make setting of DF flag more robust
8. simplify and regularize port mapping of listen sockets

arvidn 01e6b93854 simplify and improve unit test for distance_exp. make some immutable variables const in the DHT implementation. instead of waking up periodically just to check if it's time to refresh the DHT secret key, set the timer to only wake up to refresh the key. If we don't have a DHT observer (to ask for our external IP) or if we don't know our external IP, don't generate a node ID based on 0.0.0.0, just generate a random ID instead. Simplified and improved node replacement logic in the routing table a little bit 2016-01-01 16:42:37 -05:00

Steven Siloti ac01ccc43a add templated wrapper around verify_message
It was too easy to forget to update the ret and size parameters
when the size of desec changed. With this change we now automatically
get the size of desc and enforce that ret has the same size.

It would be nice if we could use bdecode_node ret[static Size] from C99
but that is not widely supported.

Steven Siloti 9f7aa7f3a6 fix segfault in put_data
If less than three nodes are found to put an item to then traversal_algorithm::start
will add router nodes. This leads to a crash in put_data::invoke when it tries to
read a token from uninitialized memory in a null_observer.

Steven Siloti c2277b3ea5 fix traversal_algorithm::done() being invoked more than once
A traversal can be done while there are still outstanding queries (i.e.
m_invoke_count is non-zero) if K good responses have already been received and
none of the outstanding queries are closer than the nodes which have responded.

When this happens and the outstanding queries eventually complete or timeout
they call traversal_algorithm::failed() or traversal_algorithm::finished() as
usual which will cause traversal_algorithm::done() to be called yet again.

The fix is to always set the done flag on all queried observers in
traversal_algorithm::done() so that the observers will refrain from calling
back into the traversal.

This also makes traversal_algorithm::abort() redundant since this was the only
thing it did before it called into done().

Steven Siloti 86fd8c3048 enable arbitrary direct dht requests and extension dht requests
If you're wondering why I used an alert for handling responses but not requests,
it's because the former was easy to do that way but the latter would have
involved some major refactoring or kludging. The DHT node is written with the
(IMO reasonable) assumption that all responses will be generated immediately, so
there was no way to easily accommodate getting a response asynchronously via
an alert.
