This commit removes the need for datatypes.JSON and makes the code a bit
cleaner by allowing us to use proper types throughout the code when it
comes to hostinfo and other datatypes on the machine object.
This allows us to remove alot of unmarshal/marshal operations and remove
a lot of obsolete error checks.
This following commits will clean away a lot of untyped data and
uneccessary error checks.
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.
After some more tests in tailscale I couldn't replicate the behavior
described in there.
When adding a rule, allowing A to talk to B the reverse connection was
instantly added to B to allow communication to B.
The previous assumption was probably wrong.
Using h.ListAllMachines also listed the current machine in the result. It's unnecessary (I don't know if it's harmful).
Breaking the check with the `matchSourceAndDestinationWithRule` broke the tests. We have a specificity with the '*' destination that isn't symetrical.
I need to think of a better way to do this. It too hard to read.
Rewrite some function to get rid of the dependency on Headscale object. This allows us
to write succinct test that are more easy to review and implement.
The improvements of the tests allowed to write the removal of the tagged hosts
from the namespace as specified here: https://tailscale.com/kb/1068/acl-tags/
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 adds a sentral cache to keep track of clients whom has
requested an expiry time, but were we need to keep hold of it until the
second request comes in.
