* Handle the decodeAuthMessage error case separatly and log to trace
Garbage data on the TCP port (e.g. from port scanners) would
cause lots of error log messages, so log this to trace and get rid
of a (little) bit of exception usage in the process.
* Remove usage of result var in rlpxAccept and rlpxConnect
* Discv4: Add ENRRequest & ENRResponse msgs to avoid fails on these
Fix#499
These messages are not implemented yet however, but just ignored.
* disc: updateExternalIp()
New public proc that can be used to inform the discovery subsystem about
a changed external IP (as reported by UPnP/NAT-PMP in some other module).
why:
Rlp errors throw exceptions which cause the dispatcher loop to
terminate the current session immediately.
details:
The DisconnectionReasonList message requires a single entry list.
Observed and now accepted deviations are:
Geth: single byte number
bor(a Geth fork): blobbed single entry list containing a number
why:
This is a legacy feature and its usage should peter out over time.
details:
Use -d:chunked_rlpx_enabled for enabling chunked RLPx message handling.
why:
For some reason, Nethermind insists on sending chunked messages to
the syncing peer. Unfortunately, for the test networks the Nethermind
modes are the importent ones as they speak eth/65 as well while others
like Geth only support eth/66 which is not implemented here, yet.
- add eventLoop to control all incoming events
- change semantic of write to asynchronously block only when send buffer is full, and not when bytes do not fit into send window
- change handling of receive buffer, to start dropping packets if the reorder buffer and receive buffer are full. Old behaviour was to async block unless there is space which could lead to resource exhaustion attacks
The ENR code used to be solely exception based, and these
exceptions where a left-over of that. They are useless as later
calls use Result anyhow.
Additionally, they cause quite the performance loss because they
are used in the "common path" for the toTypedRecord call, e.g.
when reading the fields of ip6, tcp6 and udp6.
Currently only setting `--styleCheck:hint` as there are some
dependency fixes required and the compiler seems to trip over the
findnode MessageKind, findnode Message field and the findNode
proc. Also over protocol.Protocol usage.
