* 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-- router hive failed CI/CD resulting from outdated reference to rpcBindAddr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)
Previously oxen-logging was erroneously hard-coded to use the target
"lokinet" for system logs. Obviously this is wrong for anything else
which uses oxen-logging and the system log. This changes our call to
add_sink to pass "lokinet" as the target rather than the config
filename, and updates oxen-logging to use that argument correctly.
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).
We're defining formats for std::chrono types, which feels wrong (because
fmt itself also has these), so just replace them with functions:
short_time_from_now(...) gives a short "in 14m12s" or "5.123s ago" time
span relative to now, given a time point. Precision gets reduced for
larger deviations from now (e.g. "4h12m ago").
ToString(Duration_t) gives a string such as "-3h22m02.123s" for a
duration.
The iterator here to skip an obsolete bootstrap wasn't properly
reassigning the iterator, so "didn't work" (though why it was hanging
for me is entirely non-obvious).
Also refactored it to simplify/clarify it a bit.
- Move logging initialization to early in Configure rather than at the
end of FromConfig so that we can add debug logging inside
Configure/FromConfig/etc.
- add said debug logging to Configure/FromConfig/etc.
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.
Adds a fallback bootstrap file path parameter to CMake, specify
-DBOOTSTRAP_SYSTEM_PATH="/path/to/file" to use.
Adds a list of (currently 1) obsolete bootstrap RouterIDs to check
bootstrap RCs against. Will not use bootstrap RCs if they're on that
list.
Log an error periodically if we appear to be an active service node but
have fewer than a set number (5) known peers.
Bumps oxen-logging version for literal _format.
* 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.
outbound=:1234
outbound=0.0.0.0:1234
outbound=
outbound=0.0.0.0
now all default to use the inbound= IP. (If multiple inbound= IPs are
given, we raise an exception to abort startup).
Only applies to routers (since clients don't have inbound IPs), and
eliminates potential weird edge cases with local system IP and routing
shenanigans.
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).
only send close packet once, before we were sending a close after we got a close causing excess log spam.
include handshake phase when checking for connection timeouts.
when we change our rc make sure to put it into nodedb too when we are a service node to prevent weirdness in dht lookups.
