This commit lets the watchtower automatically create hidden services
by giving it a pointer to a TorController. The server was also slightly
refactored so that it was not the sole owner of the TorController.
After renewing the certificate, the new certificate wasn't actually
loaded and used, causing the old one to be used until lnd was restarted.
This fixes that by reloading it after it has been written.
This commit makes lnd recreate its TLS certificate if the config's
tlsextradomains or tlsextraips changed. This is useful, since earlier
user would have to manually delete the files to trigger lnd to recreate
them.
To ensure users don't accidentally have their TLS certificate recreated,
we gate it behind a flag --tlsautorefresh that defaults to false.
Adds a global Authenticate method that can be used to get the
atuhentication options needed to call the grpc server.
Currently meant only for used with the mobile bindings, so we use the
admin macaroon.
Earlier we used emtpy grpc server options if custom listeners were set.
This was done to disable TLS. Now, we reuse the same server options as
for the regular listeners, in a move towards enabling TLS also here.
ListenerCfg allows passing custom listeners to the main method, to be
used for the wallet unlocker and rpc server. If these are set these will
be used instead of the regular RPC listeners.
Some time ago, we modified `lncli` to accept larger responses from the
server, up to 50MB. However, we failed to update the REST proxy, which
is in a sense, a client to the regular RPC server. As a result, users
can't currently hit the `/v1/graph` endpoint, as it'll fail with an
error.
In this PR, we update the proxy's dial options to allow it to receive
larger responses from the actual gRPC server. This is only a temporary
measure however, as we'll eventually want to expose some sort of
pagination for the end client.
The server was kept alive long after it stopped being used. This caused
problems for services using long-lived GRPC connections which might be
created before wallet unlocked. They got stuck connected to the wallet
unlock service needing a restart.
With the introduction of the WatchtowerClient RPC subserver, the lnd
configuration flag to specify private watchtowers for the client is no
longer needed and can lead to confusion upon users. Therefore, we remove
the flag completely, and only rely on the watchtower client being active
through a new --wtclient.active flag.
In this commit, we establish a new pattern to always log errors before
returning them to the higher level caller, which then prints the error
to stdout/stderr. Errors returned are usually lowercase, but we decide
not to apply this rule here as these errors should not be chained
forward.
A cleanup closure is not included when an error is returned, causing the
defer to execute and triggering the following panic:
panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0x105da38]
