```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.
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.

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.

* 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

* 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.
Fixeszerotier/ZeroTierOne#1179
Co-authored-by: Joseph Henry <joseph.henry@zerotier.com>
* 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
* Check if null is passed to VirtualNetworkConfig.equals and name fixes
* ANDROID-96: Simplify and use return code from node_init directly
* Windows arm64 (#2099)
* ARM64 changes for 1.12
* 1.12 Windows advanced installer updates and updates for ARM64
* 1.12.0
* Linux build fixes for old distros.
