- makes the html/template for /register follow the same formatting
as /apple and /windows
- adds a <title> element
- minor change for consistency's sake
This commit removes the two extra caches (oidc, requested time) and uses
the new central registration cache instead. The requested time is
unified into the main machine object and the oidc key is just added to
the same cache, as a string with the state as a key instead of machine
key.
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 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.
This commits tries to dismantle the complicated "if and or" in the
RegistrationHandler by factoring out the "is Registrated" into a root
if.
This, together with some new comments, should hopefully make it a bit
easier to follow what is happening in all the different cases that needs
to be handled when a Node contacts the registration endpoint.
This tries to make the same functions emit and consume the same type of
data all over the application.
If a function transform data, it should emit new data, not a pointer.
This commit adds some Prometheus metrics to /metrics in headscale.
It will add the standard go metrics, some automatic gin metrics and some
initial headscale specific ones.
Some of them has been added to aid debugging #97 (loop bug)
In the future, we can use the metrics to get rid of the sleep in the
integration tests by checking that our expected number of nodes has been
registered:
```
headscale_machine_registrations_total
```
This commit moves toNode to the bottom of the file, and adds a helper
function for lists of Machines to be converted.
It also adds string helpers for Machines and lists of machines.
Lastly it splits getPeers into getDirectPeers, which exist in the same
namespace, and getShared, which is nodes shared with the namespace.
getPeers is kept as a function putting together the two lists for
convenience.
This commit rewrites a bunch of the code to always use *Machine instead
of a mix of both, and a mix of tailcfg.Node and Machine.
Now we use *Machine, and if tailcfg.Node is needed, it is converted just
before needed.
This function migrates more poll functions (including keepalive) to
poll.go to keep it somehow in the same file.
In addition it makes changes to improve the stability and ensure nodes
get the appropriate updates from the headscale control and are not left
in an inconsistent state.
Two new additions is:
omitpeers=true will now trigger an update if the clients are not already up
to date
keepalive has been extended with a timer that will check every 120s if
all nodes are up to date.
This commit removes most of the locks in the PollingMap handler as there
was combinations that caused deadlocks. Instead of doing a plain map and
doing the locking ourselves, we use sync.Map which handles it for us.
