In this commit, we fix an issue that would cause peers running lnd 0.12
to not be able to connect to existing peers due to a feature bit
compatibility issue. In a recent PR we started to downgrade our required
feature bit for static key from required to optional, if we had a legacy
(non-tweakless) open with the peer then we would unset the required bit
and set the optional bit to ensure we could still connect to them.
The change implementing this new version of downgrade failed _also_
unset the bit (the required bit) in the "legacy global" feature bit
section. This caused the `RawFeatureVector.Merge` method to fail as we
would have the required bit set in the `GlobalFeatures` section, but the
optional bit set in the `Features` section. The `Merge` method ensures
that a required and optional bit can't be set in two different locations
for the same feature.
This PR fixes this issue by also unsetting the bit in the
`GlobalFeatures` field in the init message.
Fixes#4871
This commit caps the update fee the initiator will send when the anchors
channel type is used. We do not limit anything on the receiver side.
10 sat/vbyte is the current default max fee rate we use. This should be
enough to ensure propagation before anchoring down the commitment
transaction.
This commit unsets option static remote key required for peers that
we have existing legacy channels with. This ensures that we can still
connect to peers that do not recognize this feature bit that we have
existing channels with.
This commit changes the logic when garbage collecting forwarding
packages such that they are removed once when the function is called,
and then again upon subsequent ticks. This allows us to bump the
peer timer to 1 hour to limit the number of db transactions happening
in lnd. The forwarding packages need to be removed initially as
otherwise a flappy node will never have them garbage collected.
In this commit, we split the database storage into two classes: remote
and local data. If etcd isn't active, then everything is actually just
local though we use two pointers everywhere. If etcd is active, then
everything but the graph goes into the remote database.
