We're removing the notion of find/lookup a singular RC, so this gets rid
of all functions which did that and replaces their usages with something
sensible.
change path control message inner message response to take just a
string, which will be a bt-encoded response with an early key for
status. If there is a timeout we pass a bt dict that only has that as
the status, else the response we de-onioned should have either an OK
status or some other error.
change messages to use new status key
correctly call Path::EnterState on path build response
- control messages can be sent along a path
- the path owner onion-encrypts the "inner" message for each hop in the
path
- relays on the path will onion the payload in both directions, such
that the terminal relay will get the plaintext "inner" message and the
client will get the plaintext "response" to that.
- control messages have (mostly, see below) been changed to be invokable
either over a path or directly to a relay, as appropriate.
TODO:
- exit messages need looked at, so they have not yet been changed for
this
- path transfer messages (traffic from client to client over 2 paths
with a shared "pivot") are not yet implemented
- RemoteRC supplants most of the functionality throughout the code of RouterContact
- Next step will be to sort out CI issues, then see if we can get rid of either LocalRC (and therefore RouterContact entirely)
- includes are now sorted in consistent, logical order; first step in an attempt to fix the tomfoolery (no relation to Tom) brought in by include-what-you-use
- shuffled around some cmake linking to simplify dependency graph
- superfluous files removed
- Get rid of CryptoManager.
- Get rid of Crypto.
- Move all the Crypto instance methods to llarp::crypto functions.
(None of them needed to be methods at all, so this is simple).
- Move sodium/ntru initialization into static initialization.
- Add llarp::csrng, which is an available llarp::CSRNG instance which is
a bit easier than needing to construct a `CSRNG rng{};` in various
places.
- Various related small simplifications/cleanups.
- almost all errors have been commented out for refactor or already refactored
- committing this prior to sorting out the cmake structure
- upcoming include-what-you-use application
- libsodium calls streamlined and moved away from stupid typedefs
- buffer handling taken away from buffer_t and towards ustrings and strings
- lots of stuff deleted
- team is working well
- re-implementing message handling in proper link_manager methods
- routing messages and surrounding code
- shim code in place for iteration and optimization after deciding what to do with buffer, string handling, and subsequent function calls
This class is cursed, but also broken under gcc-12. Apply some lipstick
to get it moving again (but we really need to refactor this because it
is a mess).
* attempt path timeout bullshittery fix
* make sure ServiceInfo always has its address set up
* do not copy intros in constuctor, ammend logging and
add assert
