- 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.
- a `static` is less verbose and otherwise identical to an empty
namespace for a single declaration like this.
- operator== on two optionals already does exactly what the `is_equal`
lambda here is doing.

* 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.
this allows you to use exit nodes without forcing routes over the interface, useful for using lokinet with an exit and selectively routing over the lokinet interface using an external socks proxy or binding to device explicitly.
* make route poker configurable, defaults to enabled but allows disabling it on runtime if desired
* add config option [network]:auto-routing to enable/disable route poker
on win32/apple reading packets from the interface does not count as an io operation.
manually trigger pump on win32/apple to pretend that it is an io event.
add platform quark function MaybeWakeUpperLayers on vpn::Interface to manaully wake up the other components on platforms that need that (ones on which packet io is not done via io events).
on non linux platforms, use uv_prepare_t instead of uv_check_t as the former triggers before blocking for io, instead of after. this better matches linux's order of operations in libuv.
- Make the main PumpLL also pump hidden services, rather than using
separate wakers in each TunEndpoint. It seems there is some
interactions that just one or the other is not enough.
- Eliminate TunEndpoint send queue -- it isn't needed as we can just
send directly.
If something needs to wake up the event loop it should be using an
async, as we are now with PumpLL(); but we had various code triggering a
wakeup, expecting that PumpLL gets called on every wakeup, which isn't
true anymore.
We trigger a pump immediately, but this is racey because we add to our
plaintext data in a worker thread; if the worker thread runs after the
pump then it ends up leaving plaintext to be handled, but there's no
wakeup until the next one.
This was the cause of seeing a random +1s and bunching added to ping
responses sometimes: it wasn't until the *next* ping goes through the
network that the plaintext queue gets processed, at which point it
flushes the old one and often the new one together.
The fix here gets rid of the map of sessions needing wakeups and instead
adds an atomic flag to all of them to let us figure out which ones
need to be flushed.
call_soon wakes up the mainloop and is often reentrant, we dont want to
ever way up the event loop but we also want to always defer the call so
we always use the workers
* use std::source_location instead of godawful macros in logging
* remove unused/absolutely haram af json logstream
* fix bug in android logger where it doesn't respect eLogNone
before when we get the list of router ids for gossip it was highly bias towards outbound sessions.
instead now we get a full list of link session router ids in random order, truncate them to be at most MaxGossipPeers number of keys, and then put them into an unordered set
* make it so that we don't set up unbound resolver when we have no resolvers provided by config
* clean up dns codepath and make it use llarp::SockAddr instead of llarp::IpAddress
* add remove_node_from_failing to remove a node by pubkey from the failing set
* if a router is deregistered we remove it from the failing set so we don't retest it
* remove a router from the failing set if we get a test success
currently creating an outbound session will cancel if we have any session
at all with the relay. instead, only cancel if we have an outbound session
to that relay. this is useful for reachability testing.
