This commit replaces `FundingLocked` found in docs using the following
command,
```shell
find . -name "*.go" -exec sed -i '' 's/FundingLocked/ChannelReady/g' {} \;
find . -name "*.go" -exec sed -i '' 's/FundingLock/ChannelReady/g' {} \;
```
We rename `ChanUpdateOptionMaxHtlc` to `ChanUpdateRequiredMaxHtlc`
as with the latest changes it is now required.
Similarly, rename `validateOptionalFields` to
`ValidateChannelUpdateFields`, export it to use it in a later commit.
Add the ability to specify messages < CustomRangeStart that will still
be treated like custom messages by lnd (rather than unknown ones). This
allows code external to lnd to handle protocol messages that are *not
yet known to lnd*.
Fixes a bug where channel update data is read until the end of the stream
rather than stopping after the specified length. This is problematic
when failure message tlv data is present, because this data is interpreted
as channel update tlv data.
This changes the call-sites in several places to use the *P2P variants
to not trigger an OOM on untrusted input. This makes the code safe with
the new tlv version. Note that the call-sites prior to this change were
also safe.
In order to reduce the number of calls to the db we try to process as
few channels as we can + try to not do extra work for each of them.
- First fetch all the channels. Then, filter all the public ones and
sort the potential candidates by remote balance.
- Filter out each potential candidate as soon as possible.
- Only check the alias if the channel supports scid aliases.
- Because we sort the channels by remote balance, we will hit the
target amount, if possible, as soon as we can.
We do not want to leak information about our remote balances, so we
shuffle the hop hints (the forced ones go always first) so the invoice
receiver does not know which channels have more balance than others.
In this commit, we add awareness of the option_shutdown_anysegwit that
permits both sides to send newer segwit based addresses. This'll
eventually enable us to send taproot addresses for co-op close.
This defines the zero-conf feature bit, the scid-alias feature bit,
the zero-conf channel type, and the scid-alias channel type. It also
defines the dependency "tree" that exists for the feature bits.
The scid-alias feature bit signals that the node requires an alias
short channel id to be sent in funding_locked. The scid-alias channel
type requires that the channel is private, in addition to some other
forwarding-related privacy measures.
This commit adds Warning messages to lnwire, as introduced in bolts/950.
It does not include reading/writing of warning messages, which will be
covered in followup commits.
Instead of erroring out with encountering an address with an unknown
type, we just store the remainder of the addrBytes as OpaqueAddrs so
that we are able to rewrite them to the wire when we re-propagate the
message.
In this commit, a new net.Addr implementation called OpaqueAddrs is
added along with a WriteOpaqueAddrs func that is called in
WriteNetAddrs. It will be used to store any address bytes that we cannot
parse due to us not being aware of the address type.
Add a test to demonstrate that if a NodeAnnouncement includes an address
with an unknown type, then we incorrectly return an error. This will be
fixed in the following commit.
This commit was previously split into the following parts to ease
review:
- 2d746f68: replace imports
- 4008f0fd: use ecdsa.Signature
- 849e33d1: remove btcec.S256()
- b8f6ebbd: use v2 library correctly
- fa80bca9: bump go modules
This was not properly enforced and would be a spec violation on the
peer's end. Also re-use a pong buffer to save on heap allocations if
there are a lot of peers. The pong buffer is only read from, so this
is concurrent safe.
