It's undefined to write to a buffer you're reading from in snprintf().
On modern glibc and musl versions, this results in the string
"/zerotier_dump.txt" being generated, i.e. in the root directory. Use a
new variable to hold the string dump.
This is done for MacOS as well. On Sequoia, at least, it's not
necessary, as it handles overlapping objects fine, but this is more
future-proof.
At the same time, include a specific error message when the dumpfile
can't be opened to help users track down problems. Also, truncate the
file so that new writes don't potentially leave stale data.
_enabled is set to true by setUpPostDecodeReceiveThreads(), so disabled
until then, but the constructor wasn't initializing it. _concurrency is
not being used before being set but for safety's sake, ensure it has a
starting value as well.
Also, remove the vestigial _rxThreadCount, which is no longer used.
Adds support for "linkSelectMethod" as the JSON configuration field name
while maintaining backward compatibility with the legacy "activeReselect"
field name.
This change aligns the JSON field name with the internal API naming
convention (setLinkSelectMethod/getLinkSelectMethod) and follows the
established pattern in the codebase where JSON field names match their
corresponding setter method names.
The implementation:
- Checks for the new field name first, then falls back to the legacy name
- Emits a deprecation warning when "activeReselect" is used
- Ensures existing configurations continue to work without modification

* Bump version in most places.
* Update official release steps for desktop
* Version bump a bunch of Rust packages.
* Windows fix for disabling MT properly.
* Release notes.
In nixpkgs we use coreutils and do not have PWD available.
This change have any downsides on normal macOS systems, but helps
nixpkgs packaging a bit.

Update the minimal compilers in documentation. As `std=c++17` is used the minimal got quite bumped from last update. For gcc 7.x would seem possibly enough, but some of the dependencies (eg. libpqxx) need 8.x at least, so setting that as documented minimum.
cpp-httplib sets IPV6_V6ONLY to false on it's sockets.
On FreeBSD, this makes all ipv4 addresses get get prefixed with ::ffff:
it makes them IPv6 addresses mapped to v4.
This is a partial fix for #2151. The cli will work again.
Something should probably also be adjusted with the httplib.
If you want to, for example, use the `allowManagementFrom` option in
local.conf
you will need to prefix it with "::ffff:", "::ffff:1.2.3.4"
which is a little surprising and inconsistent between BSD and other OSs.
Want to show it in UIs. So need to get it via API.
It's also a pain to look up. You have to go to external docs.
zerotier-cli info -j
```json
"config": {
"settings": {
"allowTcpFallbackRelay": true,
"forceTcpRelay": true,
"homeDir": "/Library/Application Support/ZeroTier/One",
```
```sh
curl -s -X POST "http://localhost:9993/controller/network/abcdabcdabcdabcd/member/1122334455"
```
Would return 200 and ZT_HOME/controller.d/abcdabcdabcdabcd/members/1122334455
would be created. Without a ZT_HOME/controller.d/abcdabcdabcdabcd.json
Then other parts of the system mistakenly think a abcdabcdabcdabcd
network sorta kinda exists and then fail in weird ways.
There was as Windows directory traversal bug in the static
file server feature. We don't use that feature, so we are ok.
We are going to use that feature soon, so we are
taking the opportunity to update.
Add /unstable/controller/network endpoint
Similar to /unstable/controller/network/{id}/member, it returns actual network objects,
instead of just network ids.
Also includes the total network count,
and each network has it's member counts in meta{}.
The current api at /controller/network/1111111111767f2f/member
Lists only the members' ID and revision number.
If you want details, you have to query each specific member.
So if you want to make a members list, and you have
10000 members on a network, you need to make
10000 http requests.
It's also in a hard to specify and use shape
{ [member-id-1]: 13, [member-id-2]: 14, ... }
GET http://localhost:9993/unstable/controller/network/1111111111767f2f/member ->
```
{
data: [ {...member1}, {...member2}, ...],
meta: { totalCount: 4, authorizedCount: 3 }
}
```
It wasn't ignoring separator characters such as the colon and hyphen.
The rules compiler automatically add a colon to separate bytes, which is
not compatible with how they are parsed.
* Better compatibility with LLVM toolchain where clang -c doesn't
support the flag, but the linker does. LLD already defaults to
noexecstack, but adding it in the linker phase will avoid errors about

If that's better we can change the PR.
Since now there are no callers of getAuthURL I deleted it.

* fix a couple of cases of writing the wrong token
* Add warning to cli for allow default on FreeBSD
It doesn't work.
Not possible to fix with deficient network
stack and APIs.
ZeroTierOne-freebsd # zerotier-cli set 9bee8941b5xxxxxx allowDefault=1
400 set Allow Default does not work properly on FreeBSD. See #580
root@freebsd13-a:~/ZeroTierOne-freebsd # zerotier-cli get 9bee8941b5xxxxxx allowDefault

* ARM64 Support for TapDriver6 (#1949)
* Release memory previously allocated by UPNP_GetValidIGD
* Fix ifdef that breaks libzt on iOS (#2050)
* less drone (#2060)
* Exit if loading an invalid identity from disk (#2058)
* Exit if loading an invalid identity from disk
Previously, if an invalid identity was loaded from disk, ZeroTier would
generate a new identity & chug along and generate a brand new identity
as if nothing happened. When running in containers, this introduces the
possibility for key matter loss; especially when running in containers
where the identity files are mounted in the container read only. In
this case, ZT will continue chugging along with a brand new identity
with no possibility of recovering the private key.
ZeroTier should exit upon loading of invalid identity.public/identity.secret #2056
* add validation test for #2056
* tcp-proxy: fix build
* Adjust tcp-proxy makefile to support metrics
There's no way to get the metrics yet. Someone will
have to add the http service.
* remove ZT_NO_METRIC ifdef
* Implement recvmmsg() for Linux to reduce syscalls. (#2046)
Between 5% and 40% speed improvement on Linux, depending on system configuration and load.
* suppress warnings: comparison of integers of different signs: 'int64_t' (aka 'long') and 'uint64_t' (aka 'unsigned long') [-Wsign-compare] (#2063)
* fix warning: 'OS_STRING' macro redefined [-Wmacro-redefined] (#2064)
Even though this is in ext, these particular chunks of code were added
by us, so are ok to modify.
* Apply default route a different way - macOS
The original way we applied default route, by forking
0.0.0.0/0 into 0/1 and 128/1 works, but if mac os has any networking
hiccups -if you change SSIDs or sleep/wake- macos erases the system default route.
And then all networking on the computer is broken.
to summarize the new way:
allowDefault=1
```
sudo route delete default 192.168.82.1
sudo route add default 10.2.0.2
sudo route add -ifscope en1 default 192.168.82.1
```
gives us this routing table
```
Destination Gateway RT_IFA Flags Refs Use Mtu Netif Expire rtt(ms) rttvar(ms)
default 10.2.0.2 10.2.0.18 UGScg 90 1 2800 feth4823
default 192.168.82.1 192.168.82.217 UGScIg
```
allowDefault=0
```
sudo route delete default
sudo route delete -ifscope en1 default
sudo route add default 192.168.82.1
```
Notice the I flag, for -ifscope, on the physical default route.
route change does not seem to work reliably.
* fix docker tag for controllers (#2066)
* Update build.sh (#2068)
fix mkwork compilation errors
* Fix network DNS on macOS
It stopped working for ipv4 only networks in Monterey.
See #1696
We add some config like so to System Configuration
```
scutil
show State:/Network/Service/9bee8941b5xxxxxx/IPv4
<dictionary> {
Addresses : <array> {
0 : 10.2.1.36
}
InterfaceName : feth4823
Router : 10.2.1.36
ServerAddress : 127.0.0.1
}
```
* Add search domain to macos dns configuration
Stumbled upon this while debugging something else.
If we add search domain to our system configuration for
network DNS, then search domains work:
```
ping server1 ~
PING server1.my.domain (10.123.3.1): 56 data bytes
64 bytes from 10.123.3.1
```
* Fix reporting of secondaryPort and tertiaryPort See: #2039
* Fix typos (#2075)
* Disable executable stacks on assembly objects (#2071)
Add `--noexecstack` to the assembler flags so the resulting binary
will link with a non-executable stack.

* Test that starting zerotier before internet works
* Don't skip hellos when there are no paths available
working on #2082
* Update validate-1m-linux.sh
* Save zt node log files on abort
* Separate test and summary step in validator script
* Don't apply default route until zerotier is "online"
I was running into issues with restarting the zerotier service while
"full tunnel" mode is enabled.
When zerotier first boots, it gets network state from the cache
on disk. So it immediately applies all the routes it knew about
before it shutdown.
The network config may have change in this time.
If it has, then your default route is via a route
you are blocked from talking on. So you can't get the current
network config, so your internet does not work.
Other options include
- don't use cached network state on boot
- find a better criteria than "online"
* Fix node time-to-online counter in validator script
* Export variables so that they are accessible by exit function
* Fix PortMapper issue on ZeroTier startup
See issue #2082
We use a call to libnatpmp::ininatpp to make sure the computer
has working network sockets before we go into the main
nat-pmp/upnp logic.
With basic exponenetial delay up to 30 seconds.
* testing
* Comment out PortMapper debug
this got left turned on in a confusing merge previously
* fix macos default route again
see commit fb6af1971 * Fix network DNS on macOS
adding that stuff to System Config causes this extra route to be added
which breaks ipv4 default route.
We figured out a weird System Coniguration setting
that works.
--- old
couldn't figure out how to fix it in SystemConfiguration
so here we are# Please enter the commit message for your changes. Lines starting
We also moved the dns setter to before the syncIps stuff
to help with a race condition. It didn't always work when
you re-joined a network with default route enabled.
* Catch all conditions in switch statement, remove trailing whitespaces
* Add setmtu command, fix bond lifetime issue
* Basic cleanups

* Add a 2nd auth token for /metrics
Allows administrators to distribute a token that only has access to read
metrics and nothing else.
Also added support for using bearer auth tokens for both types of tokens
Separate endpoint for metrics #2041
* Update readme
* fix a couple of cases of writing the wrong token
getAuthURL() was not calling zeroidc::free_cstr(url);
the only place authAuthURL is called, the url can be retrieved
from the network config instead.
You could alternatively copy the string and call free_cstr in getAuthURL.
If that's better we can change the PR.
Since now there are no callers of getAuthURL I deleted it.

Switching `/t:ZeroTierOne:Rebuild` to just `/t:ZeroTierOne` allows the Windows build to use the rust cache. `/t:ZeroTierOne:Rebuild` cleared the cache before building.
refactored the old control plane code to use [cpp-httplib](https://github.com/yhirose/cpp-httplib) instead of a hand rolled HTTP server. Makes the control plane code much more legible. Also no longer randomly stops responding.

The check code wasn't running.
I don't know why !defined(TARGET_OS_IOS) would exclude code on
desktop macOS. I did a quick search and changed it to defined(TARGET_OS_MAC).
Not 100% sure what the most correct solution there is.
You can verify the old and new versions with
`ifconfig | grep temporary`
plus
`zerotier-cli info -j` -> listeningOn
This was getting called outside of the check for existing ips
Because of the added ifdef and a brace getting moved to the
wrong place.
```
if (! n.tap()->addIp(*ip)) {
fprintf(stderr, "ERROR: unable to add ip address %s" ZT_EOL_S, ip->toString(ipbuf));
}
WinFWHelper::newICMPRule(*ip, n.config().nwid);
```
Still unknown as to why, but the call to `nc->GetProperties()` can fail
when setting a friendly name on the Windows virtual ethernet adapter.
Ensure that `ncp` is not null before continuing and accessing the device
GUID.

ZeroTier 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 peertopeer 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.

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 peertopeer, though we offer free (but slow) relaying for users who cannot establish peertopeer 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."

## License
A small amount of third party code is also included in ZeroTier and is not subject to our BSL license. See [AUTHORS.md](AUTHORS.md) for a list of third party code, where it is included, and the licenses that apply to it. All of the third party code in ZeroTier is liberally licensed (MIT, BSD, Apache, public domain, etc.).
See [LICENSE-MPL.txt](LICENSE-MPL.txt) for all code in node/, osdep/. service/, and everywhere else except ext/ and nonfree/.
### Getting Started
See [nonfree/LICENSE.md](nonfree/LICENSE.md) for all non-free ("source available") portions of this repository.
Everything in the ZeroTier world is controlled by two types of identifier: 40-bit/10-digit *ZeroTier addresses* and 64-bit/16-digit *network IDs*. These identifiers are easily distinguished by their length. A ZeroTier address identifies a node or "device" (laptop, phone, server, VM, app, etc.) while a network ID identifies a virtual Ethernet network that can be joined by devices.
ZeroTier addresses can be thought of as port numbers on an enormous planet-wide enterprise Ethernet smart switch supporting VLANs. Network IDs are VLAN IDs to which these ports may be assigned. A single port can be assigned to more than one VLAN.
A ZeroTier address looks like `8056c2e21c` and a network ID looks like `8056c2e21c000001`. Network IDs are composed of the ZeroTier address of that network's primary controller and an arbitrary 24-bit ID that identifies the network on this controller. Network controllers are roughly analogous to SDN controllers in SDN protocols like [OpenFlow](https://en.wikipedia.org/wiki/OpenFlow), though as with the analogy between VXLAN and VL2 this should not be read to imply that the protocols or design are the same. You can use our convenient and inexpensive SaaS hosted controllers at [my.zerotier.com](https://my.zerotier.com/) or [run your own controller](controller/) if you don't mind messing around with JSON configuration files or writing scripts to do so.
### Project Layout
The base path contains the ZeroTier One service main entry point (`one.cpp`), self test code, makefiles, etc.
-`artwork/`: icons, logos, etc.
-`attic/`: old stuff and experimental code that we want to keep around for reference.
-`controller/`: the reference network controller implementation, which is built and included by default on desktop and server build targets.
-`debian/`: files for building Debian packages on Linux.
-`doc/`: manual pages and other documentation.
-`ext/`: third party libraries, binaries that we ship for convenience on some platforms (Mac and Windows), and installation support files.
-`include/`: include files for the ZeroTier core.
-`java/`: a JNI wrapper used with our Android mobile app. (The whole Android app is not open source but may be made so in the future.)
-`node/`: the ZeroTier virtual Ethernet switch core, which is designed to be entirely separate from the rest of the code and able to be built as a stand-alone OS-independent library. Note to developers: do not use C++11 features in here, since we want this to build on old embedded platforms that lack C++11 support. C++11 can be used elsewhere.
-`osdep/`: code to support and integrate with OSes, including platform-specific stuff only built for certain targets.
-`rule-compiler/`: JavaScript rules language compiler for defining network-level rules.
-`service/`: the ZeroTier One service, which wraps the ZeroTier core and provides VPN-like connectivity to virtual networks for desktops, laptops, servers, VMs, and containers.
-`windows/`: Visual Studio solution files, Windows service code, and the Windows task bar app UI.
-`zeroidc/`: OIDC implementation used by ZeroTier service to log into SSO-enabled networks. (This part is written in Rust, and more Rust will be appearing in this repository in the future.)
### Build and Platform Notes
To build on Mac and Linux just type `make`. On FreeBSD and OpenBSD `gmake` (GNU make) is required and can be installed from packages or ports. For Windows there is a Visual Studio solution in `windows/`.
- **Mac**
- Xcode command line tools for macOS 10.13 or newer are required.
- Rust for x86_64 and ARM64 targets *if SSO is enabled in the build*.
- **Linux**
- The minimum compiler versions required are GCC/G++ 4.9.3 or CLANG/CLANG++ 3.4.2. (Install `clang` on CentOS 7 as G++ is too old.)
- Linux makefiles automatically detect and prefer clang/clang++ if present as it produces smaller and slightly faster binaries in most cases. You can override by supplying CC and CXX variables on the make command line.
- Rust for x86_64 and ARM64 targets *if SSO is enabled in the build*.
- **Windows**
- Visual Studio 2022 on Windows 10 or newer.
- Rust for x86_64 and ARM64 targets *if SSO is enabled in the build*.
- **FreeBSD**
- GNU make is required. Type `gmake` to build.
-`binutils` is required. Type `pkg install binutils` to install.
- Rust for x86_64 and ARM64 targets *if SSO is enabled in the build*.
- **OpenBSD**
- There is a limit of four network memberships on OpenBSD as there are only four tap devices (`/dev/tap0` through `/dev/tap3`).
- GNU make is required. Type `gmake` to build.
- Rust for x86_64 and ARM64 targets *if SSO is enabled in the build*.
Typing `make selftest` will build a *zerotier-selftest* binary which unit tests various internals and reports on a few aspects of the build environment. It's a good idea to try this on novel platforms or architectures.
### Running
Running *zerotier-one* with `-h` option will show help.
On Linux and BSD, if you built from source, you can start the service with:
sudo ./zerotier-one -d
On most distributions, macOS, and Windows, the installer will start the service and set it up to start on boot.
A home folder for your system will automatically be created.
The service is controlled via the JSON API, which by default is available at 127.0.0.1 port 9993. We include a *zerotier-cli* command line utility to make API calls for standard things like joining and leaving networks. The *authtoken.secret* file in the home folder contains the secret token for accessing this API. See [service/README.md](service/README.md) for API documentation.
Here's where home folders live (by default) on each OS:
* **Windows**: `\ProgramData\ZeroTier\One` (That's the default. The base 'shared app data' folder might be different if Windows is installed with a non-standard drive letter assignment or layout.)
### Basic Troubleshooting
For most users, it just works.
If you are running a local system firewall, we recommend adding a rules permitting zerotier. If you installed binaries for Windows this should be done automatically. Other platforms might require manual editing of local firewall rules depending on your configuration.
See the [documentation site](https://docs.zerotier.com/zerotier/troubleshooting) for more information.
The Mac firewall can be found under "Security" in System Preferences. Linux has a variety of firewall configuration systems and tools.
On CentOS check `/etc/sysconfig/iptables` for IPTables rules. For other distributions consult your distribution's documentation. You'll also have to check the UIs or documentation for commercial third party firewall applications like Little Snitch (Mac), McAfee Firewall Enterprise (Windows), etc. if you are running any of those. Some corporate environments might have centrally managed firewall software, so you might also have to contact IT.
ZeroTier One peers will automatically locate each other and communicate directly over a local wired LAN *if UDP port 9993 inbound is open*. If that port is filtered, they won't be able to see each others' LAN announcement packets. If you're experiencing poor performance between devices on the same physical network, check their firewall settings. Without LAN auto-location peers must attempt "loopback" NAT traversal, which sometimes fails and in any case requires that every packet traverse your external router twice.
Users behind certain types of firewalls and "symmetric" NAT devices may not be able to connect to external peers directly at all. ZeroTier has limited support for port prediction and will *attempt* to traverse symmetric NATs, but this doesn't always work. If P2P connectivity fails you'll be bouncing UDP packets off our relay servers resulting in slower performance. Some NAT router(s) have a configurable NAT mode, and setting this to "full cone" will eliminate this problem. If you do this you may also see a magical improvement for things like VoIP phones, Skype, BitTorrent, WebRTC, certain games, etc., since all of these use NAT traversal techniques similar to ours.
If a firewall between you and the Internet blocks ZeroTier's UDP traffic, you will fall back to last-resort TCP tunneling to rootservers over port 443 (https impersonation). This will work almost anywhere but is *very slow* compared to UDP or direct peer to peer connectivity.
Additional help can be found in our [knowledge base](https://zerotier.atlassian.net/wiki/spaces/SD/overview).
### Prometheus Metrics
Prometheus Metrics are available at the `/metrics` API endpoint. This endpoint is protected by an API key stored in `metricstoken.secret` to prevent unwanted information leakage. Information that could be gleaned from the metrics include joined networks and peers your instance is talking to.
Access control is via the ZeroTier control interface itself and `metricstoken.secret`. This can be sent as a bearer auth token, via the `X-ZT1-Auth` HTTP header field, or appended to the URL as `?auth=<token>`. You can see the current metrics via `cURL` with the following command:
To configure a scrape job in Prometheus on the machine ZeroTier is running on, add this to your Prometheus `scrape_config`:
- job_name: zerotier-one
honor_labels: true
scrape_interval: 15s
metrics_path: /metrics
static_configs:
- targets:
- 127.0.0.1:9993
labels:
group: zerotier-one
node_id: $YOUR_10_CHARACTER_NODE_ID
authorization:
credentials: $YOUR_METRICS_TOKEN_SECRET
If neither of these methods are desirable, it is probably possible to distribute metrics via [Prometheus Proxy](https://github.com/pambrose/prometheus-proxy) or some other tool. Note: We have not tested this internally, but will probably work with the correct configuration.
Metrics are also available on disk in ZeroTier's working directory:
