This commit changes the definition of the
constraints in the ChannelConstraints struct
to specify that these are all constraints the
*owner* of the set of constraints must *never
violate*.
This is done to make it easier to check that
a particular node is not violating any
constraint for a gien update, as before it
could violate constraints found both in its
local and the remote contraints.
This commit adds the `tlsextraip` flag to the cli to add an
ip to the generated certificate. This is usefull when using
a loadbalancer to access the node.
This commit fixes a deadlock scenario caused when some
switch methods are waiting for a response on the
command's done/err chan. However, no such response will
be delivered if the main event loop has already exited.
This is resolved by selecting on the command's done/err chan
and the server's quit chan simultaneously.
After a shutdown has been initiated, both registrations
for spend ntfns and publishing txns can fail. The current
behavior in the face of such failures is to continue trying,
which is fine if we are online. However, this causes an
infinite loop during shutdown, and lnd cannot exit since
the routine is tracked by the brar's waitgroup.
A simple fix is to select on the brar's quit channel after
detecting a failure from either, allowing the breach arbiter
to break out of this death cycle.
Fixes a minor indexing bug that could cause the
utxonursery to accidentally overwrite CSV
witnesses with other CLTV witnesses when populating
a sweep txn. Each type of output is treated
separately internally, the bug is introduced by
using the relative indexes of both sets as the final
indexes into the txins.
The fix adds an offset, equal to the number of CSV
outputs, to the relative indexes of the CLTV inputs.
This matches the order in which CSV and CLTV outputs
are added to the raw txn.
In this commit, we make an API change that’s meant to reduce the amount
of garbage we generate when doing pathfinding or syncing nodes with our
latest graph state. Before this commit, we would always have to fully
decode the public key and signatures when reading a edge or vertex
struct. For the edges, we may need several EC operations to fully
decode all the pubkeys. This has been seen to generate a ton of
garbage, as well as slow down path finding a good bit.
To remedy this, we’ll now only ever read the *raw* bytes from disk. In
the event that we actually need to verify a signature (or w/e), only
*then* will we fully decode everything.
In this commit, we replace all instances of *btcec.PublicKey within the
announcement messages with a simple [33]byte. We do this as usually we
don’t need to immediately validate an announcement, therefore we can
avoid the scalar multiplications during decoding.
In this commit, we add a new signature type. We’ll use this type to
avoid fully decoding a signature on the wire into a btcec.Signature.
This type is only really needed when we need to do signature
validation, as a result, always encoding it is a waste. Several helper
methods have been added to the new struct in order to ensure that we
can use it in the existing codebase without substantial issues.
This commit adds the `lnnet` package which contains an
implementation of the newly created LightningNet interface which
multiplexes the Dial and DNS-related functions to use net
by default and torsvc if a flag is specified. This modularization
makes for cleaner code.
This commit adds a new interface named NetInterface and two
implementations of it: RegularNet & TorProxyNet. These two structs
are used in config.go in an attempt to clean up the code and
abstract away the dialer and DNS functions.
This commit adds a new module named 'torsvc' which houses all Tor
functionality in an attempt to isolate it and make it reusable in
other projecs. Some additional tweaks were made to config.go and
to the bootstrapper.
This commit adds Tor support. Users can set the --TorSocks flag
to specify which port Tor's SOCKS5 proxy is listening on so that
lnd can connect to it. When this flag is set, ALL traffic gets
routed over Tor including DNS traffic. Special functions for
DNS lookups were added, and since Tor doesn't natively support
SRV requests, the proxySRV function routes connects us to
a DNS server via Tor and SRV requests can be issued directly
to the DNS server.
