Adds knobs to configure three aspects of the OpenID Connect flow:
* Custom scopes to override the default "openid profile email".
* Custom parameters to be added to the Authorize Endpoint request.
* Domain allowlisting for authenticated principals.
* User allowlisting for authenticated principals.
current logic is not safe as it will allow an IP that isnt persisted to
the DB to be given out multiple times if machines joins in quick
succession.
This adds a lock around the "get ip" and machine registration and save
to DB so we ensure thiis isnt happning.
Currently this had to be done three places, which is silly, and outlined
in #294.
This commit change the default behaviour and remove the notion of namespaces between the hosts. It allows all namespaces to be only filtered by the ACLs. This behavior is closer to tailsnet.
This commit converts all the uses of wgkey to the new key interfaces.
It now has specific machine, node and discovery keys and we now should
use them correctly.
Please note the new logic which strips a key prefix (in utils.go) that
is now standard inside tailscale.
In theory we could put it in the database, but to preserve backwards
compatibility and not spend a lot of resources on accounting for both,
we just strip them.
This commit changes the way CLI and grpc-gateway communicates with the
gRPC backend to socket, instead of localhost. Unauthenticated access now
goes on the socket, while the network interface will require API key (in
the future).
This commit reworks getAvailableIp with a "simpler" version that will
look for the first available IP address in our IP Prefix.
There is a couple of ideas behind this:
* Make the host IPs reasonably predictable and in within similar
subnets, which should simplify ACLs for subnets
* The code is not random, but deterministic so we can have tests
* The code is a bit more understandable (no bit shift magic)
This commit makes the IP prefix used to generate addresses configurable
to users. This can be useful if you would like to use a smaller range or
if your current setup is overlapping with the current range.
The current range is left as a default
