Jason Rhinelander	7982581cfd	Revisit/reduce quic logging ... Demote many things to Trace.	4 years ago
Jason Rhinelander	3c630b260a	Don't install stream forwarding here ... Stream forward on the client-side TCP connection gets set up within in initial_client_data_handler (which also handles reading the initial stream version byte).	4 years ago
Jason Rhinelander	f534103971	Simplify/fix expiry timer logic ... Also fix a potential transmission delay because `again()` wasn't being called when the expiry is already passed (i.e. meaning we should run immediately).	4 years ago
Jason Rhinelander	ac34835c12	Fix/refactor stream closing ... Make stream closing with expiring connections work better. Fixes an issue where the stream's uv_async could outlive the stream and/or connection and segfault.	4 years ago
Jason Rhinelander	60c813d306	Schedule retransmit after blocked send ... In the standalone plainquic code we triggered a retransmit when the socket became writeable again, but that doesn't work here, so just schedule it right away to let ngtcp2 worry about retrying.	4 years ago
Jason Rhinelander	71beae5923	Stop retransmit timer when destroying a connection ... Otherwise we segfault because it outlives the Connection.	4 years ago
Jason Rhinelander	027243cbcc	Remove obsolete fixme	4 years ago
Jason Rhinelander	db2344505f	Update ngtcp2	4 years ago
Jason Rhinelander	233cb86191	Sever tunnel links earlier ... When we get an error on the tcp connection immediately sever the link to the quic tunnel so that it doesn't keep trying to forward data to it.	4 years ago
Jeff Becker	73572b317b	stuff	4 years ago
Jason Rhinelander	4cea33a139	Fix Server's missing opt-out of ring buffer ... For now we still steal buffers from uvw. In the future I'd like to change that, but it's still uvw work-in-progress to support custom data allocators, and so for now we still steal data buffers from uvw.	4 years ago
Jason Rhinelander	99954f7501	Add some more useful debug logging	4 years ago
Jason Rhinelander	b8be889291	Add missing client TCP accept/forwarding handlers ... Somehow the TCP client connection accept and stream forwarding got dropped in the quic refactor.	4 years ago
Jason Rhinelander	738f16366b	Try outbound convos if no inbound convos work (FIXME) ... FIXME - eliminate this block of code that used to be an `else` before PR'ing.	4 years ago
Jason Rhinelander	183abd58aa	Add more checks and logging ... Most of the logging here is Trace level so needs a Debug build to not get compiled away.	4 years ago
Jason Rhinelander	44fc941c32	Set port properly in server-to-client reply packets ... ngtcp2 was rejecting them because we have the port when constructing, but then it was 0 on the return packet (which ngtcp2 drops because it's coming from an unknown/invalid path).	4 years ago
Jason Rhinelander	a1a152b5c3	Disable building ngtcp2 example code	4 years ago
Jeff Becker	6bb23aa956	patch	4 years ago

Jeff Becker	708e408c30	various fixups and cleanups ... * wire up last of the quic stuff * clean up udp packet generation code * pass EndpointBase not quic tunnel for quic stuff * add {n,h}uint16_t::FromString * add nuint_t::FromString * make AlignedBuffer::IsZero non constant time call for speed	4 years ago
Jeff Becker	211a051444	add quic_tester.py script for hitting rpc endpoints to test quic	4 years ago
Jeff Becker	100a953a23	make the lokinet endpoint code work ... still needs the quic sides to work	4 years ago
Jeff Becker	7098f46d60	rpc endpoint for triggering quic tunnel	4 years ago
Jeff Becker	838b968d8f	re add static build for all internal lokinet libs	4 years ago

Jason Rhinelander	752879d712	QUIC lokinet integration refactor ... 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.	4 years ago
Jason Rhinelander	158ea4a951	Add isIPv4/isIPv6 to SockAddr	4 years ago
Jason Rhinelander	2ca7ef7f5f	Rename isRouter -> isSNode ... The isRouter wording was quite confusing, especially in a call such as: router->Configure(config, opts.isRouter, nodedb)	4 years ago
Jason Rhinelander	1d6ad7284c	Fix cursed formatting	4 years ago
Jason Rhinelander	d588f777c7	Fix logging of std::byte values ... They were failing to compile if output because implicit integer promotion doesn't work for std::byte's (but rather needs an explicit std::to_integer call).	4 years ago
Jason Rhinelander	e27fdf4c9a	Simplify/unify SendTo* methods ... Overload them to the same name to make it easier to call and/or visit them with either a RouterID, Address, Variant, or ConvoTag.	4 years ago
Jason Rhinelander	104f63543f	Change MaybeGetLoop to a virtual member func ... Minor simplification.	4 years ago
Jeff Becker	a1a1b2e2bc	remove superflous include	4 years ago

Jason Rhinelander	39d31df059	no-op LogTrace(); print chars as ints ... - LogTrace() (and LogTraceTag, etc.) are now no-ops for release builds. (hoping there are no side effects in trace logging!) - renamed llarp::_Log to llarp::_log because _Log is a reserved keyword - change logging code to implicitly convert 1-byte types (char, unsigned char, uint8_t) to ints so that we print them as numeric values rather than raw chars because, more often than not, printing a single char is trying to log an 8-bit value.	4 years ago
