In this commit, we fix an issue where we would always assume the dust
limit was Bitcoin's dust limit, rather than the active chain. This would
lead to issues when attempting to open channels on the Litecon chain.
In this commit, we add and enforce a min fee rate for commitment
transactions created, and also any updates we propose to the remote
party. It's important to note that this is only a temporary patch, as
nodes can dynamically raise their min fee rate whenever their mempool is
saturated.
Fixes#1330.
This commit changes cancelReservationCtx to gold the resMtx from start
to finish. Earlier it would lock at different times only when accessing
the maps, meaning that other goroutines (I'm looking at you
PeerTerminationWatcher) could come in and grab the context in between
locks, possibly leading to a race.
This commit moves the responsibility of sending a funding error on the
reservation error channel inside failFundingFlow, reducing the places we
need to keep track of sending it.
This commit fixes an issue in funding manager startup,
where a goroutine reads from a range value. The method in
question could cause a channel to be announced at the
wrong time.
This may have been a cause for certain channels having
phantom HTLCs before they had even received the funding
locked message from the remote peer.
This is fixed simply by using the locally scoped
variable passed in as an argument to the goroutine.
This commit fixes a bug within the funding manager, where we would use
the wrong min_htlc_value parameter. Instead of attributing the custom
passed value for MinHtlc to the remote's constraints, we would add it to
our own constraints.
This commit fixes a bug that would cause the local and remote commitment
to be incompatible when using custom remote CSV delay when opening a
channel. This would happen because we wouldn't store the CSV value
before we received the FundingAccept message, and here we would use the
default value.
This commit fixes this by making the csv value part of the
reservationWithCtx struct, such that it can be recorded for use when the
FundingAccept msg comes back.
In this commit we add a new command line option (and a sane default) to
allow users to specify the *smallest* inbound channel that they'll
accept. Having a higher-ish limit lets users limit their channels, and
also avoid a series of very low value "spam" channels.
The new option is --minchansize, and expressed in satoshis. If we
receive an inbound channel request for a value smaller than this, then
we'll immediately reject it.
In this commit, we fix a minor bug in the prior versions of lnd. Before
this commit, if we received a new inbound connection for channel
creation, the channel was created, and then the peer disconnected, we
wouldn't automatically reconnect.
In this commit we fix this issue by overloading the WatchNewChannel
method to also accept the peer's ID so we can add it to the set of
persistent connections.
In this commit, we raise the min channel size to 20k satoshis. This
will be evaluated before we check for dusty commitments. The goal of
this is to ensure ample room for fees at current, and future fee
levels.
Before previous commits were squashed into this commit, zombie
reservations were cleaned up individually when they timed out.
However, this made the code more complex because each reservation
had its own individual timer and thus it would have required the
timer being cancelled any time the reservation was cancelled,
which would have been harder to maintain. With this commit,
zombie reservations are cleaned up by a zombie sweeper that is
set off by a ticker instead, to make the code more maintainable.
This commit alters the behavior of the fundingmanager to
rebroadcast the funding transaction of all pending-open
channels upon restart. This is applied only to single-funder
channels for which we are the initiator, and helps ensure that
funding txns do not get stuck in the face of failures or restarts.
In this commit, we fix an existing bug in the funding manager, that can
be triggered if the user is connecting to a node over Tor, and then
attempts to open a channel. An existing fix was added for the case that
the receiving node established the channel, but this now makes that case
symmetric.
This commit changes the failFundingFlow to accept an error, which will
only be sent to the remote the peer if it is among the
ReservationErrors or ErrorCode. This is done to ensure we don't send
errors that contain information we don't want to leak.
This commit adds wallet_best_block_timestamp to the gRPC interface.
This is done in order to allow clients to calculate progress while
lnd syncs to the blockchain. wallet_best_block_timestamp is exposed
via the GetInfo() rpc call. Additionally, IsSynced() returns the
WalletBestBlockTimestamp as the second value in the tuple
that is returned, providing additional detail when querying about the
status of the sync. The BtcWallet interface has also been updated
accordingly.
This commit was created to support the issue to
[Add progress bar for chain sync] (lightninglabs/lightning-app#10) in
lightning-app
This commit makes more channel constraints available
via closures part of the fundingConfig, moving them
from the reservation.RemoteChanConstraints method.
