disc: updateExternalIp() (#495)
* 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).

Don't use exceptions for enr get call (#453)
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.

Style fixes according to --styleCheck:usages (#452)
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.

Merge pull request #450 from etan-status/reject-whoareyou-len
reject WHOAREYOU packets with non-empty message
2021-12-14 16:22:25 +01:00
Etan Kissling 45387ad4d2
reject WHOAREYOU packets with non-empty message
This changes the `discv5` parser to reject malformed WHOAREYOU packets
that have a non-0 message length. The extra data used to be ignored.
The `message` part of WHOAREYOU packets is always empty.
See https://github.com/ethereum/devp2p/blob/master/discv5/discv5-wire.md

Etan Kissling 172dad7968
more specific type check in `encryptGCM`
Narrowed the type of `encryptGCM`'s `key` parameter from
`openarray[byte]` to `AesKey`, same as already used for `decryptGCM`.

Adjust logging when node is not reachable but enrAutoUpdate is on (#436)

enrAutoUpdate is on or off to avoid confusion whether or not the
node might still become reachable.

Revert the useless async change for queryRandom (#432) 2021-11-22 23:14:37 +01:00
Kim De Mey 086162183c
Make queryRandom async and add exports (#431)
queryRandom was currently only async for the `enrField` version.
However the basic queryRandom is also exported and thus gets
changed so it can be properly used as async proc.

Also added exports for the modules of which objects are used in
the discovery public API.

Fix logDistance for BE arch and remove toBytes for NodeId (#427)
toBytes for NodeId wasn't selected by compiler byt if it does
get selected, it will fail on the test cases due to the
countdown that is done in logDistance.
Set to toBytesBE properly now and do countup, that should make
it correct also for BE architecture.

Removed toBytes to avoid confusion and avoid this one being
selected ever. The only place toBytes for NodeId was used is in
sessions.nim makeKey func and there also the stint one
(thus native endianness) was selected in Nim 1.2.x.
Native endianness is fine there as it is only an internal
representation.

Enr rlp lists (#408)

Allow for tcp/udp ports to always be configured (#402)
* Allow for tcp/udp ports to always be configured

- Allow for an ENR to be build with tcp and udp ports also when
no IP address is provided
- In the address set-up always provide best efforttcp and udp ports
also when configuration of external ip (and/or ports) fails.
