With the new btcd version we can specify our own listen address
generator function for any btcd nodes. This should reduce flakiness as
the previous way of getting a free port was based on just picking a
random number which lead to conflicts.
We also double the default values for connection retries and timeouts,
effectively waiting up to 4 seconds in total now.
This adds the scenario to the local force close test cases where a node
force closes one of its channels, then lose state (or do recovery)
before the commmitment is confirmed. Without the previous commit this
would go undetected.
outdated local state
This commit fixes a bug that would cause us to not sweep our local
output in case we force closed, then lost state or attempted recovery.
The reason being that we would use or local commit height when deriving
our scripts, which would be incorrect. Instead we use the extracted
state number to derive the correct scripts, allowing us to sweep the
output.
Allthough being an unlikely scenario, we would leave money on chain in
this case without any warning (since we would just end up with an empty
delay script) and forget about the spend.
Similar to what we did for the local state handling, we extract handling
all known remote states we can act on (breach, current, pending state)
into its own method.
Since we want to handle the case where we lost state (both in case of
local and remote close) last, we don't rely on the remote state number
to check which commit we are looking at, but match on TXIDs directly.
The tests didn't really roll back the channel state, so we would only
rely on the state number to determine whether we had lost state. Now we
properly roll back the channel to a previous state, in preparation for
upcoming changes.
Since it was added, we never maintained the file leading to decay in the
set of "actual" code owners. In practice, the current set up ends up
assign most reviews to 2 or so active contributors. I think the idea
itself is sound, but the current implementation leads to certain
reviewers being over-assigned PRs, which at times causes those PRs to
stagnate since pretty much every PR gets assigned to the same set of
people.
In certain container set ups, it's useful to optionally have lnd just shutdown if it detects that its certs are expired, as assuming there's a hypervisor to restart the container/pod, then upon restart, lnd will have fully up to date certs.
This commit introduces a change in the key format used to reserve/lookup
session-key-indexes. Currently the reservations are stored under the
tower id, however this creates issues when multiple clients are using
the same database since only one reservation is permitted per tower.
We fix this by appending the blob type to the session-key-index locator.
This allows multiple clients to reserve keys for the same tower, but
still limits each client to one outstanding reservation. The changes are
made in a way such that we fall back to the legacy format if the a
reservation under the new format is not found, but only if the blob type
matches blob.TypeAltruistCommit, which is so far the only actively
deployed blob type.
To avoid the "Error outside of test" log and to properly terminate the
test if a sub test fails, we need to correctly invoke them using the
RunTestCase method.
In this commit, we add a new option to toggle gossip rate limiting. This
new option can be useful in contexts that require near instant
propagation of gossip messages like integration tests.
With this commit we make it possible to use an Onion v2 hidden service
address as the Neutrino backend.
This failed before because an .onion address cannot be looked up and
converted into an IP address through the normal DNS resolving process,
even when using a Tor socks proxy.
Instead, we turn any v2 .onion address into a fake IPv6 representation
before giving it to Neutrino's address manager and turn it back into an
Onion host address when actually dialing.
If we use a chain backend that only understands IP addresses (like
Neutrino for example), we need to turn any Onion v2 host addresses into
a fake IPv6 representation, otherwise it would be resolved incorrectly.
To do this, we use the same fake IPv6 address format that bitcoind and
btcd use internally to represent Onion v2 hidden service addresses.
Currently if the tower hangs up during session negotiation there is no
backoff applied. We add backoff here to avoid excessive CPU/network
utilization during unexpected failures.
Currently the ForceQuit call is scheduled after trying to stop the
backup queue. In certain cases, the call to stop the queue never
finishes, which means the force quit is never scheduled. We rememdy by
scheduling this call before any other operations to ensure we can always
exit ungracefully if necessary.
In this commit, we extend the `BuildRoute` method and RPC on the router
sub-server to accept a raw payment address which will be included as
part of an MPP payload for the finla hop. This change actually also
allows users to craft their own MPP paths using BuildRoute+SendToRoute.
Our primary goal however, was to fix some broken itests since we now
require the payAddr to be present for ALL payments other than key send
payments.
In this commit, we move to start rejecting any normal payments that
aren't keysend, if they don't also include the MPP invoice payload. With
this change, we require that some sort of e2e secret (either the payment
addr or the keysend pre-image) is present in a payload before we'll
accept the payment.
The second portion of the commit also updates all current tests in the
package. We kept the base `TestSettleInvoice` test in-tact as it still
exercises some useful behavior. However, we've removed all cases that
allow an overpayment, as the new MPP logic doesn't allow overpayment for
various reasons. In addition to this, some of the returned errors are
slightly different, tho the actual behavior is equivalent.
In this commit, we add a new RequiresFeature method to the feature
vector struct. This method allows us to check if the set of features
we're examining *require* that the even portion of a bit pair be set.
This can be used to check if new behavior should be allowed (after we
flip new bits to be required) for existing contexts.
In this commit, we move to start requiring the payment addr feature bit
in the invoices we produce. With this change, if a user attempts to pay
one of our invoices (assuming they're also an lnd node), then they'll
receive an error when they attempt to pay. At this point, *most* lnd
nodes should be on v0.11 at this point, and this change will notify any
lagging wallet authors to update, as these payments are generally more
secure.
This change was largely motivated by an increase in high disk usage as a
result of channel update spam. With an in memory graph, this would've
gone mostly undetected except for the increased bandwidth usage, which
this doesn't aim to solve yet. To minimize the effects to disks, we
begin to rate limit channel updates in two ways. Keep alive updates,
those which only increase their timestamps to signal liveliness, are now
limited to one per lnd's rebroadcast interval (current default of 24H).
Non keep alive updates are now limited to one per block per direction.
