Because the original dcrec secp256k1 library that is used for the
Schnorr signature primitives uses different hash algorithms than the
btcd secp256k1 library. Therefore pulling in the wrong library can lead
to weird and unexpected errors. We try to make it harder to make the
mistake by not using the library directly in lnd in the first place.
Note that it is still indirectly needed by the btcd secp256k1 library,
therefore the module dependency is still expected to be there, just
moved to the indirect section.
In this commit, we add a new field `TapTweak` to be used for key path
spends. Before this commit, we'd overload the existing `WitnessScript`
field to pass this information to the signing context. This was
confusing as for tapscript spends, this was the leaf script, which
mirrors the other script based spending types.
With this new filed, users need to set this to the script root for
keypath spends where the output key commits to a real merkle root, and
nothing when bip 86 spending is being used.
To make the signing even more explicit, we also add a new field called
sign_method with an enum type that differentiates between the different
segwit v0 and v1 signing methods.
Fixes https://github.com/lightningnetwork/lnd/issues/6446.
Since we might now be given a whole list of UTXOs in the PrevOutputs
field of the SignOutputRaw RPC, the previous output fetcher might
contain the information we require for the remote signing case. So
instead of failing if our wallet doesn't know each input that's being
spent, we fall back to the UTXO information contained in the previous
outputs.
Add a new chainview interface test that runds the chainview tests
against a bitcoind node that we are getting block and tx notifications
from using the rpc interface.
With this commit we support fee calculation in coin selection for p2tr
inputs. We assume that coins in our UTXO selection are only BIP0086
coins. Any other input types with different spend paths won't be
selected by the wallet assembler.
This updates the list of tags used for `release` builds in the release
documentation. `peersrpc`, `kvdb_postgres`, and `kvdb_etcd` are now
automatically included in `make release` or `make release-install`
builds.
This adds a list of tags that can be used when building or installing
lnd from source. Links to relevant code, protobuf definitions, or
documentation are included to illustrate the purpose of each tag.
Closes#3598.
