This commit adds three optional command line flags to the
encryptdebugpackage: --peers, --onchain and --channels.
Each of them adds the output of extra commands to the encrypted debug
package.
With this commit we add a new way to encrypt and decrypt a sensitive
payload: By using Diffie-Hellman over a local and remote key to derive
at a shared secret key.
With this commit we add a new helper function that recursively turns the
runtime configuration into a flat key/value map that is human-readable,
using the dot notation for nested values that is also used in the config
file or command line flags.
We take into account a fee buffer of twice the current fee rate
of the commitment transaction plus an additional htlc output
when we are the opener of the channel hence pay when publishing the
commitment transaction. This buffer is not consensus critical
because we only consider it when we are in control of adding a
new htlc to the state. The goal is to prevent situations
where we push our local balance below our channel reserve due to
parallel adding of htlcs to the state. Its not a panacea for these
situations but until we have __option_simplified_update__ deployed
widely on the network its a good precaution to protect against
fee spikes and parallel adding of htlcs to the update log.
Moreover the way the available balance for a channel changed.
We now need to account for a fee buffer when we are the channel
opener. Therefore all the tests had to be adopted.
In this commit, we convert the `JusticeKit` struct to an interface.
Then, we add two implementations of that interface:
1) The `legacyJusticeKit` which implements all the methods of
`JusticeKit`
2) The `anchorJusticKit` which wraps the `legacyJusticeKit` and just
re-implements the `ToRemoteOutputSpendInfo` method since.
In preparation for the next commit which will introduce the `JusticeKit`
interface, here we just move the code related to building the actual
justice kit packet into a separate file.
In this commit a new enum, CommitmentType, is introduced and initially
there are 3 CommitmentTypes: Legacy, LegacyTweakless and Anchor.
Then, various methods are added to `CommitmentType`. This allows us to
remove a bunch of "if-else" chains from the `wtclient` and `lookout`
code. This will also make things easier to extend when a new commitment
type (like Taproot) is added.
We add a WhenSome that'll pass in the actual underlying value, and not
just the record.
We also add `SomeRecord` to make it easier to create TLV records w/
`Some` set.
This will be useful when decoding optional TLV records, as we can use
this to look up in the `typeMap` for a given field to see if we decoded
it or not.
With this change, callers can now examine a struct instance of the
`TlvType` instance to figure out programmatically which integer type is
maps to. This'll be useful when decoding optional TLV types into a wire
struct (knowing when to set it to Some vs None).
In this commit, we modify the RecordT type to allow callers to re-use
the Record definition of a different type, but use the new type param to
override the integer type used on the wire.
This will let use do things like encode a signature using the same
RecordProducer instance, but with a diff type in another context.
The upcoming use for this is allowing our `lnwire.Sig` type to be
encoded in the same message using distinct TLV integer types (new co-op
close protocol).
