Variables related to the default configuration file location are
needed if the config parsing is happening externally. We export them
so they don't need to be copied to projects that use lnd as a library.
To allow external configuration parsing and validation, this commit
exports the function that checks a configuration for sanity.
Also because we touch the code, we need to fix all linter errors.
This provides users an alternative over the SAFECOOKIE authentication
method, which may not be as useful if users are connecting to a remote
Tor sevrer due to lnd not being able to retrieve the cookie file.
This commit enables the user to specify he is not interested in
automatically close channels with pending payments that their
corresponding htlcs have timed-out.
By requiring a configurable grace period uptime of our node
before closing such channels, we give a chance to the other node to
properly cancel the htlc and avoid unnecessary on-chain transaction.
In mobile it is very important for the user experience as otherwise
channels will be force closed more frequently.
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.
This commit adds handling code for the key send custom record. If this
record is present and its hash matches the payment hash, invoice
registry will insert a new invoice into the database "just in time". The
subsequent settle flow is unchanged. The newly inserted invoice is
picked up and settled. Notifications will be broadcast as usual.
This commit gets upfront shutdown scripts from openchannel and
acceptchannel wire messages sent from our peer and sets upfront
shutdown scripts in our open and accept channel messages when
the remote peer supports option upfront shutdown and we have
the feature enabled.
This commit beings the process of deprecating unsafe-disconnect. Many
moons ago this was disallowed to prevent concurency bugs surrounding
reconnect. Despite the name, it has been safe to enable this feature for
well over a year, as several PRs have been merged that addressed the
possible issues that existed when the feature was added.
In this commit, we begin to enforce a maximum channel commitment fee for
channel initiators when attempting to update their commitment fee. Now,
if the new commitment fee happens to exceed their maximum, then a fee
update of the maximum fee allocation will be proposed instead if needed.
A default of up to 50% of the channel initiator's balance is enforced
for the maximum channel commitment fee. It can be modified through the
`--max-channel-fee-allocation` CLI flag.
In this commit, we add a new build tag protected sub-config for legacy
protocol features. The goal of this addition is to be able to default to
new feature within lnd, but expose hooks at the config level to allow
integration tests to force the old behavior to ensure that we're able to
support both the old+new versions.
htlcs
config: Adding RejectHTLC field in config struct
This commit adds a RejectHTLC field in the config struct in config.go.
This allows the user to run lnd as a node that does not accept onward
HTLCs.
htlcswitch/switch: Adding a field RejectHTLC to the switch config
This commit adds a field RejectHTLC to the switch config. When the
switch receives an HTLC it will check this flag and if the HTLC is not
from the source hop, the HTLC will be rejected.
htlcswitch/switch: adding check for RejectHTLC flag and incomingChanID
This commit adds a check when receiving UpdateAddHTLC. The check looks
for the RejectHTLC flag set and whether the HTLC is from the sourceHop
(the local switch). If the HTLC is not from the sourceHop, then we
reject the HTLC and return a FailChannelDisabled error.
server: adding RejectHTLC field to initialization of switch
lnd_test: adding test for RejectHTLC
This commit adds a test which tests that a node with the --rejecthtlc
flag will reject any onward HTLCs but still can receive direct HTLCs and
can send HTLCs.
