With the introduction of the max CLTV limit parameter, nodes are able to
reject HTLCs that exceed it. This should also be applied to path
finding, otherwise HTLCs crafted by the same node that exceed it never
left the switch. This wasn't a big deal since the previous max CLTV
limit was ~5000 blocks. Once it was lowered to 1008, the issue became
more apparent. Therefore, all of our path finding attempts now have a
restriction of said limit in in order to properly carry out HTLCs to the
network.
Fixes https://github.com/lightningnetwork/lnd/issues/3357. When
start_time isn't specified, its default value is 0. This meant when
users explicitly specified a start_time of 0, we would incorrectly set
start_time to 24 hours in the past. Now, n0 means n0.
The policy update logic that resided part in the gossiper and
part in the rpc server is extracted into its own object.
This prepares for additional validation logic to be added for policy
updates that would otherwise make the gossiper heavier.
It is also a small first step towards separation of our own channel data
from the rest of the graph.
In this commit, we fix a bug where if a user updates a forwarding policy to be
zero, the update will be applied to the policy correctly on-disk, but not
in-memory.
We solve this issue by having the gossiper return the list of on-disk updated
policies and passing these policies to the switch, so the switch can assume
that zero-valued fields are intentional and not just uninitialized.
In this commit, we add a new field to the Hop proto to allow callers to
be able to specify TLV records for the SendToRoute call, and also to be
able to display TLV records that were used during regular path finding.
We also update SendPayment to support dest TLV records.
Debug invoices are rarely used nowadays, but keep asking for maintenance
every time refactoring in primarily the invoice registry occurs. We have
passed the cost/benefit tipping point, so therefore the debug invoice
concept is removed in this commit.
Previously the debughtlc flag also controlled whether hodl masks were
active. It is safe to remove that additional condition because the hodl
masks are still guarded by the dev build tag.
Not all errors that occur when serving client requests in the gRPC
server are logged. As a result, at times, we can be lacking critic
information that can be used to debug issues that pop up. With this PR,
we create a basic streaming+unary interceptor that will log all errors
that occur when servicing calls.
The current format looks something like this in the logs when an error
occurs:
```
[ERR] RPCS: [/lnrpc.Lightning/SendCoins]: decoded address is of unknown format
```
lnrpc/rpc.proto: updates RoutingPolicy last_update number
rpcserver: adding LastUpdate field to marshalDbEdge
This commit adds a LastUpdate field to each RoutingPolicy, it will show
the time each RoutingPolicy was updated.
lnrpc: regenerating proto files
In this commit two fields were added to the Channl RPC result in both
open and pending states.
The fields: local_chan_reserve, remote_chan_reserve represents the
reservation the nodes are rquired to keep in both sides of the channel.
This is usefull when calculating the "real" inbound and outbound
liquidity in an accurate way.
This commit fixes a but where restarting LND at the same process causes
It to fail.
The problem resides in the fact that an array of permissions is
initialized as a package variable and when creating the
RPCServer all subserver permissions are appended while checking for
duplicates.
On subsequent restart this array is left over from the previous run and
being populated again with the same permissions causing a duplicate
error.
The solution is simple, just to extract out the initial permissions to
a separate function and call it from the context is is needed.
Earlier versions of ListPayments only included completed payments. We
return to this behavior by ignore all other payments if the nonSucceeded
boolean is not set in the request.
Start the Prometheus exporter in rpcserver.go if monitoring is enabled through the
build tag. Also allow users to specify what address they want the Prometheus
exporter to be listening on.
This commit moves the default timeout out of router and thereby fixes a
bug that caused SendToRoute to not return the actual error, but a
timeout result instead. SendToRoute only tries a single route, so a
timeout should never happen.
This commit makes the router use the ControlTower to drive the payment
life cycle state machine, to keep track of active payments across
restarts. This lets the router resume payments on startup, such that
their final results can be handled and stored when ready.
Now that the success resolver preimage field is always populated by the
incoming contest resolver, preimage lookups earlier in the
process (channel and channel arbitrator) can mostly be removed.
This commit restructures the creation of various tls related object. It
also fixes a bug where wildcard IP addresses where only instantiated for
the main RPC server and not the WalletUnlocker service.
In this commit, we modify the `closeObserver` to fast path the DLP
dispatch case if we detect that the channel has been restored. We do
this as otherwise, we may inadvertently enter one of the other cases
erroneously, causing us to now properly look up their dlp commitment
point.
lnd_test: adding address validation for send coins
The commit adds a test that checks that when a user calls sendcoins, the
receiving address is validated according to the current network. If the
address is not compatible with the current network, it will return an
error to the user.
rpcserver: adding a check for compatible network in SendCoins
This commit adds a check in SendCoins that checks whether the receiving
address is compatible with the current network.
Fixes#2677.
