Network Controller Microservice
======
-ZeroTier's 16-digit network IDs are really just a concatenation of the 10-digit ZeroTier address of a network controller followed by a 6-digit (24-bit) network number on that controller. Fans of software defined networking will recognize this as a variation of the familiar [separation of data plane and control plane](http://sdntutorials.com/difference-between-control-plane-and-data-plane/) SDN design pattern.
+Every ZeroTier virtual network has a *network controller*. This is our reference implementation and is the same one we use to power our own hosted services at [my.zerotier.com](https://my.zerotier.com/). Network controllers act as configuration servers and certificate authorities for the members of networks. Controllers are located on the network by simply parsing out the first 10 digits of a network's 16-digit network ID: these are the address of the controller.
-This code implements the *node/NetworkController.hpp* interface and provides a SQLite3-backed network controller microservice. Including it in the build allows ZeroTier One to act as a controller and create/manage networks.
+As of ZeroTier One version 1.2.0 this code is included in normal builds for desktop, laptop, and server (Linux, etc.) targets, allowing any device to create virtual networks without having to be rebuilt from source with special flags to enable this feature. While this does offer a convenient way to create ad-hoc networks or experiment, we recommend running a dedicated controller somewhere secure and stable for any "serious" use case.
-This is the same code we use to run [my.zerotier.com](https://my.zerotier.com/), which is a web UI and API that runs in front of a pool of controllers.
+Controller data is stored in JSON format under `controller.d` in the ZeroTier working directory. It can be copied, rsync'd, placed in `git`, etc. The files under `controller.d` should not be modified in place while the controller is running or data loss may result, and if they are edited directly take care not to save corrupt JSON since that can also lead to data loss when the controller is restarted. Going through the API is strongly preferred to directly modifying these files.
-### Building
+### Upgrading from Older (1.1.14 or earlier) Versions
-On Linux, Mac, or BSD you can create a controller-enabled build with:
+Older versions of this code used a SQLite database instead of in-filesystem JSON. A migration utility called `migrate-sqlite` is included here and *must* be used to migrate this data to the new format. If the controller is started with an old `controller.db` in its working directory it will terminate after printing an error to *stderr*. This is done to prevent "surprises" for those running DIY controllers using the old code.
- make ZT_ENABLE_NETWORK_CONTROLLER=1
+The migration tool is written in nodeJS and can be used like this:
-You will need the development headers and libraries for SQLite3 installed.
+ cd migrate-sqlite
+ npm install
+ node migrate.js </path/to/controller.db> </path/to/controller.d>
-### Running
+Very old versions of nodeJS may have issues. We tested it with version 7.
-After building and installing (`make install`) a controller-enabled build of ZeroTier One, start it and try:
+### Scalability and Reliability
- sudo zerotier-cli /controller
+Controllers can in theory host up to 2^24 networks and serve many millions of devices (or more), but we recommend spreading large numbers of networks across many controllers for load balancing and fault tolerance reasons. Since the controller uses the filesystem as its data store we recommend fast filesystems and fast SSD drives for heavily loaded controllers.
-You should see something like:
-
- {
- "controller": true,
- "apiVersion": 2,
- "clock": 1468002975497,
- "instanceId": "8ab354604debe1da27ee627c9ef94a48"
- }
-
-When started, a controller-enabled build of ZeroTier One will automatically create and initialize a `controller.db` file in its home folder. This is where all the controller's data and persistent state lives. If you're upgrading an old controller it will upgrade its database schema automatically on first launch. Make a backup of the old controller's database first since you can't go backward.
-
-Controllers periodically make backups of their database as `controller.db.backup`. This is done so that this file can be more easily copied/rsync'ed to other systems without worrying about corruption. SQLite3 supports multiple processes accessing the same database file, so `sqlite3 /path/to/controller.db .dump` also works but can be slow on a busy controller.
-
-Controllers can in theory host up to 2^24 networks and serve many millions of devices (or more), but we recommend running multiple controllers for a lot of networks to spread load and be more fault tolerant.
+Since ZeroTier nodes are mobile and do not need static IPs, implementing high availability fail-over for controllers is easy. Just replicate their working directories from master to backup and have something automatically fire up the backup if the master goes down. Many modern orchestration tools have built-in support for this. It would also be possible in theory to run controllers on a replicated or distributed filesystem, but we haven't tested this yet.
### Dockerizing Controllers
ZeroTier network controllers can easily be run in Docker or other container systems. Since containers do not need to actually join networks, extra privilege options like "--device=/dev/net/tun --privileged" are not needed. You'll just need to map the local JSON API port of the running controller and allow it to access the Internet (over UDP/9993 at a minimum) so things can reach and query it.
-### Implementing High Availability Fail-Over
-
-ZeroTier network controllers are not single points of failure for networks-- in the sense that if a controller goes down *existing* members of a network can continue to communicate. But new members (or those that have been offline for a while) can't join, existing members can't be de-authorized, and other changes to the network's configuration can't be made. This means that short "glitches" in controller availability are not a major problem but long periods of unavailability can be.
-
-Because controllers are just regular ZeroTier nodes and controller queries are in-band, controllers can trivially be moved without worrying about changes to underlying physical IPs. This makes high-availability fail-over very easy to implement.
-
-Just set up two cloud hosts, preferably in different data centers (e.g. two different AWS regions or Digital Ocean SF and NYC). Now set up the hot spare controller to constantly mirror `controller.db.backup` from its active sibling.
-
-If the active controller goes down, rename `controller.db.backup` to `controller.db` on the hot spare and start the ZeroTier One service there. The spare will take over and has now become the active controller. If the original active node comes back, it should take on the role of spare and should not start its service. Instead it should start mirroring the active controller's backup and wait until it is needed.
-
-The details of actually implementing this kind of HA fail-over on Linux or other OSes are beyond the scope of these docs and there are many ways to do it. Docker orchestration tools like Kubernetes can also be used to accomplish this if you've dockerized your controller.
-
### Network Controller API
The controller API is hosted via the same JSON API endpoint that ZeroTier One uses for local control (usually at 127.0.0.1 port 9993). All controller options are routed under the `/controller` base path.
The controller microservice does not implement any fine-grained access control (authentication is via authtoken.secret just like the regular JSON API) or other complex mangement features. It just takes network and network member configurations and reponds to controller queries. We have an enterprise product called [ZeroTier Central](https://my.zerotier.com/) that we host as a service (and that companies can license to self-host) that does this.
-All working network IDs on a controller must begin with the controller's ZeroTier address. The API will *allow* "foreign" networks to be added but the controller will have no way of doing anything with them.
+All working network IDs on a controller must begin with the controller's ZeroTier address.

-(The `ipLocalRoutes` field appeared in older versions but is no longer present. Routes will now show up in `routes`.)
+Recent changes:
-Two important things to know about networks:
+ * The `ipLocalRoutes` field appeared in older versions but is no longer present. Routes will now show up in `routes`.
+ * The `relays` field is gone since network preferred relays are gone. This capability is replaced by VL1 level federation ("federated roots").
- - Networks without rules won't carry any traffic. See below for an example with rules to permit IPv4 and IPv6.
- - Managed IP address assignments and IP assignment pools that do not fall within a route configured in `routes` are ignored and won't be used or sent to members.
- - The default for `private` is `true` and this is probably what you want. Turning `private` off means *anyone* can join your network with only its 16-digit network ID. It's also impossible to de-authorize a member as these networks don't issue or enforce certificates. Such "party line" networks are used for decentralized app backplanes, gaming, and testing but are not common in ordinary use.
+Other important points:
-**IPv6 Auto-Assign Modes:**
+ * Networks without rules won't carry any traffic. If you don't specify any on network creation an "accept anything" rule set will automatically be added.
+ * Managed IP address assignments and IP assignment pools that do not fall within a route configured in `routes` are ignored and won't be used or sent to members.

Such "party line" networks are used for decentralized app backplanes, gaming, and testing but are otherwise not common.
-This field is (for legacy reasons) a comma-delimited list of strings. These can be `rfc4193`, `6plane`, and `zt`. RFC4193 and 6PLANE are special addressing modes that deterministically assign IPv6 addresses based on the network ID and the ZeroTier address of each member. The `zt` mode enables IPv6 auto-assignment from arbitrary IPv6 IP ranges configured in `ipAssignmentPools`.
+**Auto-Assign Modes:**
-**Relay object format:**
+Auto assign modes (`v4AssignMode` and `v6AssignMode`) contain objects that map assignment modes to booleans.
-Relay objects define network-specific preferred relay nodes. Traffic to peers on this network will preferentially use these relays if they are available, and otherwise will fall back to the global rootserver infrastructure.
+For IPv4 the only valid setting is `zt` which, if true, causes IPv4 addresses to be auto-assigned from `ipAssignmentPools` to members that do not have an IPv4 assignment. Note that active bridges are exempt and will not get auto-assigned IPs since this can interfere with bridging. (You can still manually assign one if you want.)

+IPv6 includes this option and two others: `6plane` and `rfc4193`. These assign private IPv6 addresses to each member based on a deterministic assignment scheme that allows members to emulate IPv6 NDP to skip multicast for better performance and scalability. The `rfc4193` mode gives every member a /128 on a /88 network, while `6plane` gives every member a /80 within a /40 network but uses NDP emulation to route *all* IPs under that /80 to its owner. The `6plane` mode is great for use cases like Docker since it allows every member to assign IPv6 addresses within its /80 that just work instantly and globally across the network.

**Rule object format:**
-Rules are matched in order of ruleNo. If no rules match, the default action is `drop`. To allow all traffic, create a single rule with all *null* fields and an action of `accept`.
+Each rule is actually a sequence of zero or more `MATCH_` entries in the rule array followed by an `ACTION_` entry that describes what to do if all the preceding entries match. An `ACTION_` without any preceding `MATCH_` entries is always taken, so setting a single `ACTION_ACCEPT` rule yields a network that allows all traffic. If no rules are present the default action is `ACTION_DROP`.
-In the future there will be many, many more types of rules. As of today only filtering by Ethernet packet type is supported.
+Rules are evaluated in the order in which they appear in the array. There is currently a limit of 256 entries per network. Capabilities should be used if a larger and more complex rule set is needed since they allow rules to be grouped by purpose and only shipped to members that need them.

+Important notes about rules engine behavior:
+
+ * IPv4 and IPv6 IP address rules do not match for frames that are not IPv4 or IPv6 respectively.
+ * `ACTION_DEBUG_LOG` is a no-op on nodes not built with `ZT_RULES_ENGINE_DEBUGGING` enabled (see Network.cpp). If that is enabled nodes will dump a trace of rule evaluation results to *stdout* when this action is encountered but will otherwise keep evaluating rules. This is used for basic "smoke testing" of the rules engine.
+ * Multicast packets and packets destined for bridged devices treated a little differently. They are matched more than once. They are matched at the point of send with a NULL ZeroTier destination address, meaning that `MATCH_DEST_ZEROTIER_ADDRESS` is useless. That's because the true VL1 destination is not yet known. Then they are matched again for each true VL1 destination. On these later subsequent matches TEE actions are ignored and REDIRECT rules are interpreted as DROPs. This prevents multiple TEE or REDIRECT packets from being sent to third party devices.
+ * Rules in capabilities are always matched as if the current device is the sender (inbound == false). A capability specifies sender side rules that can be enforced on both sides.

The controller can only know a member's `fromAddr` if it's able to establish a direct path to it. Members behind very restrictive firewalls may not have this information since the controller will be receiving the member's requests by way of a relay. ZeroTier does not back-trace IP paths as packets are relayed since this would add a lot of protocol overhead.
