If new default scopes are added to the underlying btcwallet
implementation, then they aren't automatically created for _existing_
wallets, only for new ones. So on startup we need to make sure all
scopes are present.
Fixes#6329.
This commit fixes a connection leak in the RPC wallet's health check. By
not closing the test connection the watch-only node would slowly stack
up connections and eventually hit the ulimit.
Fixes an issue with SignOutputRaw in remote signing mode where we
weren't able to sign on the remote signer if we only provided the public
key or only the family/index (and not both).
Fixes part of an issue detected in lightninglabs/loop#457.
We need to be able to query the watch-only wallet about a public key
when trying to sign with a key that we don't know the family or index
of. The easiest way to do that is to leverage the wallet's address index
to query the derivation path for a public key.
To give the RPC wallet access to that functionality, we need to expose
the method on the WalletController interface.
With `OutputDetail` now containing the destination addresses, the `DestAddresses` field can be removed from the `lnwallet.TransactionDetail`. It is already populated when needed for backwards compatibility to `lnrpc.TransactionDetail` via `OutputDetail.Addresses`.
Adds the output script and amount to the `DestOutput` field of `TransactionDetails`, as well as sets the flag `isOurAddress` if the output is controlled by the node's wallet.
A new `DestOutputs` field contains additional information on destinations of a transaction described with the `TransactionDetail` structure.
The additional information inside `DestOuputs` denote the output script and amount, as well as a flag `IsOurAddress` if the address is controlled by the node's wallet.
Before this commit, we we were trying to sweep an anchor output, and
that output was spent by someone else (not the sweeper), then we would
report this back to the original resolver (allowing it to be cleaned
up), and also remove the set of inputs spent by that transaction from
the set we need to sweep.
However, it's possible that if a user is spending unconfirmed outputs,
then the wallet is holding onto an invalid transaction, as the outputs
that were used as inputs have been double spent elsewhere.
In this commit, we fix this issue by recursively removing all descendant
transactions of our past sweeps that have an intersecting input set as
the spending transaction. In cases where a user spent an unconfirmed
output to funding a channel, and that output was a descendant of the now
swept anchor output, the funds will now properly be marked as available.
Fixes#6241
This commit was previously split into the following parts to ease
review:
- 2d746f68: replace imports
- 4008f0fd: use ecdsa.Signature
- 849e33d1: remove btcec.S256()
- b8f6ebbd: use v2 library correctly
- fa80bca9: bump go modules
In this commit, we increase the legacy fee limit threshold (the amount
below which we'll allow 100% of funds to go to fees for the non-v2 RPC
calls) from 50 sats to 1k sats.
If we're signing for an UTXO that isn't known to the wallet, then the
UTXO's pk script _must_ be set in the sign descriptor. Otherwise we run
into a generic PSBT serialization error when running in a remote signing
setup.
To enable converting an existing wallet with private key material into a
watch-only wallet on first startup with remote signing enabled, we add a
new flag. Since the conversion is a destructive process, this shouldn't
happen automatically just because remote signing is enabled.
This fixeslightninglabs/loop#437 by adding all accounts that are used
in liquidity products such as Loop or Pool. Since both of these products
use key families below 255, we can get by with that number.
The alternative to creating way too many accounts (which increases the
default wallet size by ~250kB) would be to hard code the exact accounts
used by Loop (99) and Pool (210). But that sounds like a bad idea given
that there could always be more accounts being added to those (or other)
products. By making sure the first 255 accounts exist, we have a lot
more flexibility in those products for choosing key families.
With the remote signing instance now not needing to know anything about
addresses or current derivation indices, we don't need to forward any
such calls to that instance and can simplify the RPCKeyRing
considerably.
The minimum relay fee is always ensured to be above our fee floor except
in the very first min relay fee query to bitcoind. This commit ensures
that the fee floor is respected in this first query.
This change avoids enforcing new reserved value when PSBT funding is not
finished yet as new inputs and outputs may still be added that could
change the outcome of the check.
This originally failed in the scenario when funding a channel from
external wallet *and depositing to on-chain wallet* was done
simultaneously in a single transaction. If such transaction confirms
then reserved UTXO is guaranteed to be available but the check didn't
take it into account.
The enforcement still occurs in the final step of PSBT funding flow, so
it is safe. It also occurs in case of non-PSBT funding.
This commit modifies the channel state machine to be able to derive the
proper commitment and second-level HTLC output scripts required by the
new script-enforced leased channel commitment type.
