Replaces custom logging system with spdlog-based oxen logging. This
commit mainly replaces the backend logging with the spdlog-based system,
but doesn't (yet) convert all the existing LogWarn, etc. to use the new
format-based logging.
New logging statements will look like:
llarp::log::warning(cat, "blah: {}", val);
where `cat` should be set up in each .cpp or cluster of .cpp files, as
described in the oxen-logging README.
As part of spdlog we get fmt, which gives us nice format strings, where
are applied generously in this commit.
Making types printable now requires two steps:
- add a ToString() method
- add this specialization:
template <>
constexpr inline bool llarp::IsToStringFormattable<llarp::Whatever> = true;
This will then allow the type to be printed as a "{}" value in a
fmt::format string. This is applied to all our printable types here,
and all of the `operator<<` are removed.
This commit also:
- replaces various uses of `operator<<` to ToString()
- replaces various uses of std::stringstream with either fmt::format or
plain std::string
- Rename some to_string and toString() methods to ToString() for
consistency (and to work with fmt)
- Replace `stringify(...)` and `make_exception` usage with fmt::format
(and remove stringify/make_exception from util/str.hpp).
Replace stream_reset (which typically isn't called) with a stream_close
handler (which is already called whether or not it was a reset). Most
importantly, the server side needs to extend the max bidi streams
counter during stream_close (otherwise we run out when we hit the
limit and new connections just stall).
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.
