Whitelisting is now always-on for relays. Disabling the option is never
used and is unsupported/unmaintained (it was, in theory, to allow
lokinet as a separate usage in a non-service-node relay mode, i.e. on a
completely separate network).
Confusingly, the option was enabled by the `[lokid]:enabled` config
parameter.
- Added call_get to ev.hpp to queue event loop operations w/ a return value
- de-mutexed NodeDB and made all operations via event loop. Some calls to NodeDB methods (like ::put_if_newer) were wrapped in call->get's, but some weren't. All function bodies were using mutex locks
- 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
- bumped version to latest main branch commit
- wired up callbacks to set RPC request stream on creation
- methods for I/O of control and data messages through link_manager
- llarp/router/router.hpp, route_poker, and platform code moved to libquic Address types
- implementing required methods in link_manager for connection establishment
- coming along nicely
- `::handle_message` is transposed; Rather than the message calling the method and taking a reference to the router, the router should have a handle_message method and take a reference to the message
- `::EndcodeBuffer` takes a string reference, to which the result of `::bt_encode()` is assigned
TODO:
- set up all the callbacks for libquic
- define control message requests, responses, commands
- plug new control messages into lokinet (path creation, network state, etc)
- plug connection state changes (established, failed, closed, etc.) into lokinet
- lots of cleanup and miscellanea

* Updated RpcServer Initialization and Logic
-- Moved all RPCServer initialization logic to rpcserver constructor
-- Fixed config logic, fxn binding to rpc address, fxn adding rpc cats
-- router hive failed CI/CD resulting from outdated reference to rpcBindAddr
-- ipc socket as default hidden from windows (for now)
the win32 and sd_notify components provided a disjointed set of
similar high level functionality so we consolidate these duplicate
code paths into one that has the same lifecycle regardless of platform
to reduce complexity of this feature.
this new component is responsible for reporting state changes to the
system layer and optionally propagating state change to lokinet
requested by the system layer (used by windows service).
Currently (from a recent PR) we aren't pinging oxend if not active, but
that behaviour ended up being quite wrong because lokinet needs to ping
even when decommissioned or deregistered (when decommissioned we need
the ping to get commissioned again, and if not registered we need the
ping to get past the "lokinet isn't pinging" nag screen to prepare a
registration).
This considerably revises the pinging behaviour:
- We ping oxend *unless* there is a specific error with our connections
(i.e. we *should* be establishing peer connections but don't have any)
- If we do have such an error, we send a new oxend "error" ping to
report the error to oxend and get oxend to hold off on sending uptime
proofs.
Along the way this also changes how we handle the current node state:
instead of just tracking deregistered/decommissioned, we now track three
states:
- LooksRegistered -- which means the SN is known to the network (but not
necessarily active or fully staked)
- LooksFunded -- which means it is known *and* is fully funded, but not
necessarily active
- LooksDecommissioned -- which means it is known, funded, and not
currently active (which implies decommissioned).
The funded (or more precisely, unfunded) state is now tracked in
rc_lookup_handler in a "greenlist" -- i.e. new SNs that are so new (i.e.
"green") that they aren't even fully staked or active yet.
If running as a service node, we ping core on a regular interval to
inform it we're running and in a good state. If we're an active
(not decommissioned or deregistered) service node and have too few
peers and thus we're not actually connected to lokinet, we should skip
that ping so core doesn't think we're ok.
* wintun vpn platform for windows
* bundle config snippets into nsis installer for exit node, keyfile persisting, reduced hops mode.
* use wintun for vpn platform
* isolate all windows platform specific code into their own compilation units and libraries
* split up internal libraries into more specific components
* rename liblokinet.a target to liblokinet-amalgum.a to elimiate ambiguity with liblokinet.so
* DNS platform for win32
* rename llarp/ev/ev_libuv.{c,h}pp to llarp/ev/libuv.{c,h}pp as the old name was idiotic
* split up net platform into win32 and posix specific compilation units
* rename lokinet_init.c to easter_eggs.cpp as that is what they are for and it does not need to be a c compilation target
* add cmake option STRIP_SYMBOLS for seperating out debug symbols for windows builds
* intercept dns traffic on all interfaces on windows using windivert and feed it into lokinet
we want to be able to have multiple locally bound dns sockets in lokinet so
i restructured most of the dns subsystem in order to make this easier.
specifically, we have a new structure to dns subsystem:
* dns::QueryJob_Base
base type for holding a dns query and response with virtual methods
in charge of sending a reply to whoever requested.
* dns::PacketSource_Base
base type for reading and writing dns messages to and from wherever they came from
* dns::Resolver_Base
base type for filtering and handling of dns messages asynchronously.
* dns::Server
contextualized per endpoint dns object, responsible for all dns related isms.
this change hides all impelementation details of all of the dns components.
adds some more helper functions for parsing dns and dealing with OwnedBuffer.
overall dns becomes less of a pain with this new structure. probably.
* immediately poke routes when we are told to use an exit so that packets get pushed which makes an exit path happen
* fix up cmake oddity in nsis section
* not gossip our rc
* not explore the network to prevent outbound session attempts
* not establish sessions to other service nodes
* close all open sessions we have to tell clients we don't want them
* catch exceptions flushing peerdb in disk thread
* don't connect out to non allowed routers
* simplify logic in RCLookupHandler::RemoteIsAllowed()
* add HaveReceivedWhitelist to I_RCLookupHandler base type
* add LooksDeregistered to Router type that tells us if we think we are deregistered
* don't allow building paths over us if we are deregistered
* add srv records in RCs if we have any
* add mechanism to add SRV records for plainquic exposed ports
* resign and republish rc or introset on srv record changes
All #ifndef guards on headers have been removed, I think,
in favor of #pragma once
Headers are now included as `#include "filename"` if the included file
resides in the same directory as the file including it, or any
subdirectory therein. Otherwise they are included as
`#include <project/top/dir/relative/path/filename>`
The above does not include system/os headers.
loop->call(...) is similar to the old logic->Call(...), but is smart
about the current thread: if called from within the event loop it simply
runs the argument directly, otherwise it queues it.
Similarly most of the other event loop calls are also now thread-aware:
for example, `call_later(...)` can queue the job directly when called if
in the event loop rather than having to double-queue through the even
loop (once to call, then inside the call to initiate the time).
- removes all the llarp_ev_* functions, replacing with methods/classes/functions in the llarp
namespace.
- banish ev/ev.h to the void
- Passes various things by const lvalue ref, especially shared_ptr's that don't need to be copied
(to avoid an atomic refcount increment/decrement).
- Add a llarp::UDPHandle abstract class for UDP handling
- Removes the UDP tick handler; code that needs tick can just do a separate handler on the event
loop outside the UDP socket.
- Adds an "OwnedBuffer" which owns its own memory but is implicitly convertible to a llarp_buffer_t.
This is mostly needed to take over ownership of buffers from uvw without copying them as,
currently, uvw does its own allocation (pending some open upstream issues/PRs).
- Logic:
- add `make_caller`/`call_forever`/`call_every` utility functions to abstract Call wrapping and
dependent timed tasks.
- Add inLogicThread() so that code can tell its inside the logic thread (typically for
debugging assertions).
- get rid of janky integer returns and dealing with cancellations on call_later: the other methods
added here and the event loop code remove the need for them.
- Event loop:
- redo everything with uvw instead of libuv
- rename EventLoopWakeup::Wakeup to EventLoopWakeup::Trigger to better reflect what it does.
- add EventLoopRepeater for repeated events, and replace the code that reschedules itself every
time it is called with a repeater.
- Split up `EventLoop::run()` into a non-virtual base method and abstract `run_loop()` methods;
the base method does a couple extra setup/teardown things that don't need to be in the derived class.
- udp_listen is replaced with ev->udp(...) which returns a new UDPHandle object rather that
needing gross C-style-but-not-actually-C-compatible structs.
- Remove unused register_poll_fd_(un)readable
- Use shared_ptr for EventLoopWakeup rather than returning a raw pointer; uvw lets us not have to
worry about having the event loop class maintain ownership of it.
- Add factory EventLoop::create() function to create a default (uvw-based) event loop (previously
this was one of the llarp_ev_blahblah unnamespaced functions).
- ev_libuv: this is mostly rewritten; all of the glue code/structs, in particular, are gone as
they are no longer needed with uvw.
- DNS:
- Rename DnsHandler to DnsInterceptor to better describe what it does (this is the code that
intercepts all DNS to the tun IP range for Android).
- endpoint:
- remove unused "isolated network" code
- remove distinct (but actually always the same) variables for router/endpoint logic objects
- llarp_buffer_t
- make constructors type-safe against being called with points to non-size-1 values
- tun packet reading:
- read all available packets off the device/file descriptor; previously we were reading one packet
at a time then returning to the event loop to poll again.
- ReadNextPacket() now returns a 0-size packet if the read would block (so that we can implement
the previous point).
- ReadNextPacket() now throws on I/O error
- Miscellaneous code cleanups/simplifications
