We might hit a connection refused error in cases where the peer connects
to us exactly as we try to connect to it. We retry the connection within
a wait predicat, as it should be the case that the other peer
establishes the connection, and the two peers actually connects.
These result in an error with the current release script as is. Those
that want to run `lnd` on their iPhone/iPad can instead use the
`gomobile` bindings.
Notably, solaris/amd64 and illumos/amd64 were added in go1.13. The
others were have been supported previously but were not build targets.
After go1.13, nacl/* will no longer be supported and plan9/* is still
considered experiemental. As a result they are omitted.
In this commit, we fix a bug that would prevent users that had
unresolved contracts at the time of update from starting their nodes.
Before we added the conf commit set, the information needed to
supplement the resolvers was found in the chain action map. As a result,
if the conf commit set is nil, then we also need to check this legacy
data to ensure that we can supplement the resolvers to the best of our
ability based on the available data.
Fixes#3549.
In this commit, we create a new `build/release` package which houses the
build instructions and scripts that we need to do deterministic builds
across Windows, Linux, and MacOS.
With this new system, it's now possible for all `lnd` developers, as
well as users to verify the posted build binaries. This wasn't possible
in prior release as only in Go 1.13 did deterministic builds becomes
easier/possible. See the new `README.md` for further details.
Without this, it was possible for a combination of our balance and max
fee allocation to result in a fee rate below the fee floor causing the
remote party to reject the update and close the channel.
In this commit, we use the recently added `chanvalidate` package to
verify channels once they have been confirmed in the funding manager. We
expose a new method on the `LightningWallet` struct: `ValidateChannels`
which calls the new shared 1st party verification code.
After the channel is fully confirmed in the funding manager, we'll now
use this newly exposed method to handle all validation. As a result, we
can remove the existing validation code in the funding manager, and rely
on the new code in isolation.
In the process of moving to use the new package, we no longer need to
fetch the outpoint directly, and instead only need to pass the funding
transaction into the new verification logic.
In this commit, we create a new `chanvalidate` package which it to house
all logic required for 1st and 3rd party channel verification. 1st party
verification occurs when we find a channel in the chain that is
allegedly ours, while 3rd party verification will occur when a peer
sends us a channel proof of a new channel.
In the scope of the recent CVE, we actually fully verified 3rd party
channels, but failed to also include those checks in our 1st party
verification code. In order to unify this logic, and prevent future
issues, in this PR we move to concentrate all validation logic into a
single function. Both 1st and 3rd party validation will then use this
function. Additionally, having all the logic in a single place makes it
easier to audit, and also write tests against.
In this commit, we move to make a full deep copy of the commitment
transaction in `getSignedCommitTx` to ensure that we don't mutate the
commitment on disk, possibly resulting in a "hot commitment".
In order to prevent future unforeseen issues, we are temporarily
disabling the ability to send custom tlv records to the receiver of a
payment. Currently the receiver does not process or expose these
additional fields via rpc or internally, so they are being disabled
until the end-to-end flow is finished and fully validated.
Without waiting, we would proceed to retrieve the remote peer's
supported features, which may have not been set due to not yet receiving
their Init message.
