This commit makes SendHTLC (we are the source) evaluate the dust
threshold of the outgoing channel against the default threshold of
500K satoshis. If the threshold is exceeded by adding this HTLC, we
fail backwards. It also makes handlePacketForward (we are forwarding)
evaluate the dust threshold of the incoming channel and the outgoing
channel and fails backwards if either channel's dust sum exceeds the
default threshold.
This commit extends the Mailbox interface with the SetDustClosure,
SetFeeRate, and DustPackets methods. This enables the mailbox to
report the dust exposure to the Switch when the Switch decides whether
to forward a dust packet. The dust is counted from the time an Add is
introduced via AddPacket until it is removed via AckPacket. This can
lead to some packets being counted twice before they are signed for,
but this is a trade-off between accuracy and simplicity.
It over-estimates the local or remote commitment's dust sum by
counting all updates in both updateLogs that are dust using the
trimmed-to-dust mechanism if applicable. The over-estimation is done
because ensuring an accurate counting is a trade-off between code
simplicity and accuracy.
A stray version of lnd was pushed out waaaay back in 2016 that can trip
up `pkg.go.dev` and things like `go get`. Using the new Go 1.16 feature,
we can now "retract" this version, which marks it as being unavailable.
With go 1.17 a change to the build flags was implemented:
https://go.googlesource.com/proposal/+/master/design/draft-gobuild.md
The formatter now automatically adds the forward-compatible build tag
format and the linter checks for them, so we need to include them in our
code.
This commit fixes a nil pointer issue when a node fails to start up.
Because require.NoErrorf() doesn't abort a test immediately if run
inside a goroutine, this lead to the test continuing with nil node
references which lead to a panic later on.
When Alice receives a CommitSig near the end of the test, the test
assumed that she wouldn't reply with a RevokeAndAck message before
shutdownAssert was called. This led to a test flake. Instead, only
call shutdownAssert after we've received the RevokeAndAck.
This is necessary and is implied by BOLT#02. Both ChannelReserve
parameters should be above both DustLimit parameters. Otherwise,
it is possible for one side to have nothing at stake.
This commit updates call-sites to use the proper dust limits for
various script types. This also updates the default dust limit used
in the funding flow to be 354 satoshis instead of 573 satoshis.

In this commit, we take an initial step towards converting the existing
breach arbiter and utxo nursery logic into contract resolvers by moving
the files as is, into the `contractcourt` pacakge.
This commit is primarily move only, though we had to massage some
interfaces and config names along the way to make things compile and the
tests run properly.
Fixes#5796.
Some historical channels might not have the forwarding packages
recorded. And since the error might be silenced, the historical channel
might be nil.
Because the PGP keys are no longer downloaded from Keybase but are used
from the repo directly, we also have to copy them to the Docker image so
we can run the script without needing to supply them through a volume.
With this commit we add a new restriction that checks that the
username in the signature file (manifest-<username>-<version>.sig) actually
does have a signing key and that the signature was created with that key.
The signature is only counted towards the minimum of 5 signatures if
that check is successful.
The changes in this commit were inspired by @kixunil in #5048.
