This fix puts an end to a saga that essentially start during the
Status Prague Meetup at the end of October 2018. At the time we were
experiencing massive issues with `Connecting...` spinners in the app in the
venue we rented. We were pulling our hairs out what to do and we could not
find the cause of the issue at the time.
Three months later I deployed the following change:
https://github.com/status-im/infra-eth-cluster/commit/63a13eed
Which used `iptables` to map the `443` port onto our `30504` Status node port
using `PREROUTING` chain and `REDIRECT` jump in order to fix issues people
have been complaining about when using WiFi networks in various venues:
https://github.com/status-im/status-react/issues/6351
Our thinking when trying to resolve the reported issue assumed that some
networks might block outgoing connections on non-standard ports other than
the usual `80`(HTTP)/`443`(HTTPS) which would disrupt Status connectivity.
While this fix could have indeed helped a few edge cases, what it really
did was cause the Status node to stop seeing actual public IPs of the clients.
But __pure accident__ this change caused the code we inherited from
`go-ethereum` implementation of DevP2P protocol to stop throttling new
incoming connections, because the IP as which they appeared was a
`172.16.0.0/12` network address of the Docker bridge.
The `go-ethereum` code used the `!netutil.IsLAN(remoteIP)` check to
avoid throttling connections from local addresses, which included the
local Docker bridge address:
https://github.com/status-im/status-go/blob/82680830/vendor/github.com/ethereum/go-ethereum/p2p/netutil/net.go#L36
The fix intended to target a small number of networks with fortified
firewall configuration accidentally resolved our issues with
`Connecting...` prompts that our application showed us en masse during
our Prauge Meetup. Part of the reason for that is that venues like that
normally give out local IP addresses and use NAT to translate them onto
the only public IP address they possess.
Since out application is supposed to be usable from within networks
behind NAT like airport WiFi networks for example, it makes no sense to
keep the inbound connection throttle time implemented in `go-ethereum`.
I'm leaving `inboundThrottleTime` in because it's used to calculate
value for `dialHistoryExpiration` in:
`vendor/github.com/ethereum/go-ethereum/p2p/dial.go`
I believe reducing that value one we deploy this change should also
increase the speed with which the Status application is able to reconnect
to a node that was temporarily unavailable, instead waiting the 5*30 seconds.

* fixed TestStatusNodeReconnectStaticPeers,
* fixed TestBackendAccountsConcurrently.
This change makes invalidation mechanism more aggressive. With a primary goal to invalidate short living nodes faster. In current setup any node that became known in terms of discovery will stay in this state until it will fail to respond to 5 queries. Removing them earlier from a table allows to reduce latency for finding required nodes.
The second change, one adds a version for discovery, separates status dht from ethereum dht.
After we rolled out discovery it became obvious that our boot nodes became spammed with irrelevant nodes. And this made discovery process very long, for example with separate dht discovery takes ~2s, with mutual dht - it can take 1m-10m and there is still no guarantee to find a max amount of peers, cause status nodes is a very small part of whole ethereum infra.
In my understanding, we don't need to be a part of ethereum dht, and lower latency is way more important for us.
Closes: #941
Partially closes: #960 (960 requires futher investigations on devices)
Now if Add is to be called it will be called before Wait, this is achieved
by doing following:
- if cancel() gets lock first and closes channelCh before spawnSync is called
we will exit right away
- if not than we will ensure that we hold a lock until syncers are spawned
so that cancel() will be blocked for this time and it will prevent whole Terminate() from
progressing
This change adds adds an ability to use different source of time for whisper:
when envelope is created it is used to set expiry
to track when envelope needs to be expired
This time is then used to check validity of the envelope when it is received. Currently If we receive an envelope that is sent from future - peer will get disconnected. If envelope that was received has an expiry less then now it will be simply dropped, if expiry is less than now + 10*2 seconds peer will get dropped.
So, it is clear that whisper depends on time. And any time we get a skew with peers that is > 20s reliability will be grealy reduced.
In this change another source of time for whisper will be used. This time source will use ntp servers from pool.ntp.org to compute offset. When whisper queries time - this offset will be added/substracted from current time.
Query is executed every 2 mins, queries 5 different servers, cut offs min and max and the computes mean value. pool.ntp.org is resolved to different servers and according to documentation you will rarely hit the same.
Closes: #687
