- 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
-- 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-- router hive failed CI/CD resulting from outdated reference to rpcBindAddr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)
refactored config endpoint
- added rpc call script (contrib/omq-rpc.py)
- added new fxns to .ini config stuff
- added delete .ini file functionality to config endpoint
- added edge case control for config endpoint
add commented out line in clang-form for header reorg later
previously we had a checking style function that passes in an optional
defaulting to nullopt as a micro optimzation, this makes the code
unnessarily obtuse.
simplify this by splitting up into 2 functions,
one for getting the unique endpoints and one for checking if the
number of them is above the minimum.
add overload for ReadyToDoLookup() that checks against constant but
can do more in the future if desired to reduce the burden on future contributors.
* 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.
Having it there (even defaulted, like this) means endpoint.hpp doesn't
have to include endpoint_state.hpp (which it otherwise would need,
because of the std::unique_ptr<EndpointState> default deleter
requirements).
When we enable/disable exit mode on this restarts the unbound DNS
responder with the DNS trampoline (or restores upstream, when disabling)
to properly route DNS requests through the tunnel (because libunbound's
direct requests don't get tunneled because unbound is inside the network
extension).
* introset path haodver tweaks
* improve warn/error messages to convey more information
* dont block on queue insertion
* reset convotag on decrypt/verify fail
* add multiple ready hooks on outbound context
* lookup introsets from close routers on dht
* continue to tick dead sessions so they expire their paths
* introset spacing
* reduce lns lookup diversity requirement for speed
* add a function to send reset convotag message
* only have 1 outbound context at a time
so it doesn't time out and get into a state that's totally screwed.
add virtual function service::Endpont::DefaultPathAlignmentTimeout() to get the timeout for path alignment
and use it for resetablishing outbound sessions
* 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
* add lokinet_add_bootstrap_rc function for adding an rc from memory
* prevent stack overflow on error closing connection in quic
* add in memory nodedb
* refactor how convotags are set as active
* add initial stubs for endpoint statistics
* refactor time stuff to be a bit cleaner
* update lnproxy script with more arguments
Refactors how quic packets get handled: the actual tunnels now live in
tunnel.hpp's TunnelManager which holds and manages all the quic<->tcp
tunnelling. service::Endpoint now holds a TunnelManager rather than a
quic::Server. We only need one quic server, but we need a separate quic
client instance per outgoing quic tunnel, and TunnelManager handles all
that glue now.
Adds QUIC packet handling to get to the right tunnel code. This
required multiplexing incoming quic packets, as follows:
Adds a very small quic tunnel packet header of 4 bytes:
[1, SPORT, ECN] for client->server packets, where SPORT is our
source "port" (really: just a uint16_t unique quic instance
identifier)
or
[2, DPORT, ECN] for server->client packets where the DPORT is the SPORT
from above.
(This also reworks ECN bits to get properly carried over lokinet.)
We don't need a destination/source port for the server-side because
there is only ever one quic server (and we know we're going to it when
the first byte of the header is 1).
Removes the config option for quic exposing ports; a full lokinet will
simply accept anything incoming on quic and tunnel it to the requested
port on the the local endpoint IP (this handler will come in a following
commit).
Replace ConvoTags with full addresses: we need to carry the port, as
well, which the ConvoTag can't give us, so change those to more general
SockAddrs from which we can extract both the ConvoTag *and* the port.
Add a pending connection queue along with new quic-side handlers to call
when a stream becomes available (TunnelManager uses this to wire up
pending incoming conns with quic streams as streams open up).
Completely get rid of tunnel_server/tunnel_client.cpp code; it is now
moved to tunnel.hpp.
Add listen()/forget() methods in TunnelManager for setting up quic
listening sockets (for liblokinet usage).
Add open()/close() methods in TunnelManager for spinning up new quic
clients for outgoing quic connections.
