Add a method to "kick" the refresh thread and re-post the tokens in the case where the thread is somehow still running & controller pushes out an AUTH_REQUIRED. This situation happens in a corner case still under investigation where the controller pushes out many copies of the network config repeatedly
See issue #750.
zerotier doesn't currently set a metric on routes. Linux
takes this to mean "0", the highest priority.
Every comment in the issue is about routing between zerotier
and lan and how they conflict.
This quick change could fix this problem for most people.
The subnet route for the zerotier network, the one with no
via, is still 0 in this patch. Just the "via" routes get
higher metrics.
If for some reason, you needed your via routes to have
higher priority, you could use a prefix work-around:
192.168.1.0/25 via 10.147.17.1
192.168.1.128/25 via 10.147.17.1
consolidated everything into the single IDC struct. Should help keep from rotating the pkce token as often & causing issues with the login window flapping
and vice versa.
For issue #1104
With some printf debugging, I was seeing:
here, src fe80::3c7a:2dff:fe0c:21ed, target 10.147.20.0, matchingPrefixBits 0, mostMatchingPrefixBits 0
here, src fd8b:d512:4fd6:255:3c99:932f:2fda:6eff, target 10.147.20.0, matchingPrefixBits 0, mostMatchingPrefixBits 0
and (matchingPrefixBits >= mostMatchingPrefixBits) would be true
Then on mac, somewhere downstream from there, the default route would
get messed up:
default via 92:29:f1:6f:2f:76 dev en0
- Can now provide the following environment variables to populate
secrets (nice for kubernetes, other situations)
- ZEROTIER_API_SECRET: authtoken.secret
- ZEROTIER_IDENTITY_PUBLIC: identity.public
- ZEROTIER_IDENTITY_SECRET: identity.secret
- Joining networks by providing them as a part of docker's "command"
array should now work properly

On certain OSes (Linux & Apple) tun#, tap#, and of course zt# are blacklisted by default, this adds wg# to the list as WireGuard is a similar popular service with wg# being the default adapter name(s) by convention.
On system shutdown, zerotier is stopped after the network and gets
itself into a connection timeout loop. It hits the TimeoutStopUSec= and
is forcibly killed by SIGKILL. Order zerotier after network.target so it
can shutdown gracefully while the network is still up.
From systemd.special(7):
at shutdown, a unit that is ordered after network.target will be stopped
before the network — to whatever level it might be set up then — is shut
down. It is hence useful when writing service files that require network
access on shutdown, which should order themselves after this target, but
not pull it in

[ZeroTier](https://www.zerotier.com) is a smart programmable Ethernet switch for planet Earth. It allows all networked devices, VMs, containers, and applications to communicate as if they all reside in the same physical data center or cloud region.
This is accomplished by combining a cryptographically addressed and secure peer to peer network (termed VL1) with an Ethernet emulation layer somewhat similar to VXLAN (termed VL2). Our VL2 Ethernet virtualization layer includes advanced enterprise SDN features like fine grained access control rules for network micro-segmentation and security monitoring.
All ZeroTier traffic is encrypted end-to-end using secret keys that only you control. Most traffic flows peer to peer, though we offer free (but slow) relaying for users who cannot establish peer to peer connections.
The goals and design principles of ZeroTier are inspired by among other things the original [Google BeyondCorp](https://static.googleusercontent.com/media/research.google.com/en//pubs/archive/43231.pdf) paper and the [Jericho Forum](https://en.wikipedia.org/wiki/Jericho_Forum) with its notion of "deperimeterization."

## Building the docker image
Due to the network being a substrate for most applications and not an application unto itself, it makes sense that many people would want to build their own image based on our formula.
The image is based on `debian:buster`.
The `Dockerfile.release` file contains build instructions for building the described image in the rest of the README. The build is multi-arch and multi-release capable.
These build arguments power the build:
-`PACKAGE_BASEURL`: The base URL of the package repository to fetch from. (default: `https://download.zerotier.com/debian/buster/pool/main/z/zerotier-one/`)
-`ARCH`: The architecture of the package, in debian format. Must match your image arch. (default: `amd64`)
-`VERSION`: **REQUIRED** the version of ZeroTier to fetch.
The `entrypoint.sh` in the docker image is a little different; zerotier will be spawned in the background and the "main process" is actually just a sleeping shell script. This allows `zerotier-one` to gracefully terminate in some situations largely unique to docker.
The `zerotier/zerotier` image requires the `CAP_NET_ADMIN` capability and the `/dev/net/tun` device must be forwarded to it.
To join a network, simply supply it on the command-line; you can supply multiple networks.
Once joining all the networks you have provided, it will sleep until terminated. Note that in ZeroTier, joining a network does not necessarily mean you have an IP or can do anything, really. You will want to probe the control socket:
```
docker exec myzerotier zerotier-cli listnetworks
```
To ensure you have a network available before trying to listen on it. Without pre-configuring the identity, this usually means going to the central admin panel and clicking the checkmark against your zerotier identity.
### Environment Variables
You can control a few settings including the identity used and the authtoken used to interact with the control socket (which you can forward and access through `localhost:9993`).
-`ZEROTIER_API_SECRET`: replaces the `authtoken.secret` before booting and allows you to manage the control socket's authentication key.
-`ZEROTIER_IDENTITY_PUBLIC`: the `identity.public` file for zerotier-one. Use `zerotier-idtool` to generate one of these for you.
-`ZEROTIER_IDENTITY_SECRET`: the `identity.secret` file for zerotier-one. Use `zerotier-idtool` to generate one of these for you.
### Tips
- Forwarding port `<dockerip>:9993` to somewhere outside is probably a good idea for highly trafficked services.
- Forwarding `localhost:9993` to a control network where you can drive it remotely might be a good idea, just be sure to set your authtoken properly through environment variables.
- Pre-generating your identities could be much simpler to do via our [terraform plugin](https://github.com/zerotier/terraform-provider-zerotier)

* Fix numerous UI issues from 1.8.0 (never fully released).
* Remove support for REALLY ancient 1.1.6 or earlier network controllers.
* MacOS IPv6 no longer binds to temporary addresses as these can cause interruptions if they expire.
* Added additional hardening against address impersonation on networks (also in 1.6.6).

go into a "coma" on some networks.
* Also groundhog day
# 2020-11-30 -- Version 1.6.2
