### Security fix: OIDC changes in Headscale 0.24.0
The following issue _only_ affects Headscale installations which authenticate
with OIDC.
_Headscale v0.23.0 and earlier_ identified OIDC users by the "username" part of
their email address (when `strip_email_domain: true`, the default) or whole
email address (when `strip_email_domain: false`).
Depending on how Headscale and your Identity Provider (IdP) were configured,
only using the `email` claim could allow a malicious user with an IdP account to
take over another Headscale user's account, even when
`strip_email_domain: false`.
This would also cause a user to lose access to their Headscale account if they
changed their email address.
_Headscale v0.24.0_ now identifies OIDC users by the `iss` and `sub` claims.
[These are guaranteed by the OIDC specification to be stable and unique](https://openid.net/specs/openid-connect-core-1_0.html#ClaimStability),
even if a user changes email address. A well-designed IdP will typically set
`sub` to an opaque identifier like a UUID or numeric ID, which has no relation
to the user's name or email address.
Headscale v0.24.0 and later will also automatically update profile fields with
OIDC data on login. This means that users can change those details in your IdP,
and have it populate to Headscale automatically the next time they log in.
However, this may affect the way you reference users in policies.
Headscale v0.23.0 and earlier never recorded the `iss` and `sub` fields, so all
legacy (existing) OIDC accounts _need to be migrated_ to be properly
secured.
#### What do I need to do to migrate?
Headscale v0.24.0 has an automatic migration feature, which is enabled by
default (`map_legacy_users: true`). **This will be disabled by default in a
future version of Headscale – any unmigrated users will get new accounts.**
The migration will mostly be done automatically, with one exception. If your
OIDC does not provide an `email_verified` claim, Headscale will ignore the
`email`. This means that either the administrator will have to mark the user
emails as verified, or ensure the users verify their emails. Any unverified
emails will be ignored, meaning that the users will get new accounts instead
of being migrated.
After this exception is ensured, make all users log into Headscale with their
account, and Headscale will automatically update the account record. This will
be transparent to the users.
When all users have logged in, you can disable the automatic migration by
setting `map_legacy_users: false` in your configuration file.
Please note that `map_legacy_users` will be set to `false` by default in v0.25.0
and the migration mechanism will be removed in v0.26.0.
<details>
<summary>What does automatic migration do?</summary>
##### What does automatic migration do?
When automatic migration is enabled (`map_legacy_users: true`), Headscale will
first match an OIDC account to a Headscale account by `iss` and `sub`, and then
fall back to matching OIDC users similarly to how Headscale v0.23.0 did:
- If `strip_email_domain: true` (the default): the Headscale username matches
the "username" part of their email address.
- If `strip_email_domain: false`: the Headscale username matches the _whole_
email address.
On migration, Headscale will change the account's username to their
`preferred_username`. **This could break any ACLs or policies which are
configured to match by username.**
Like with Headscale v0.23.0 and earlier, this migration only works for users who
haven't changed their email address since their last Headscale login.
A _successful_ automated migration should otherwise be transparent to users.
Once a Headscale account has been migrated, it will be _unavailable_ to be
matched by the legacy process. An OIDC login with a matching username, but
_non-matching_ `iss` and `sub` will instead get a _new_ Headscale account.
Because of the way OIDC works, Headscale's automated migration process can
_only_ work when a user tries to log in after the update.
Legacy account migration should have no effect on new installations where all
users have a recorded `sub` and `iss`.
</details>
<details>
<summary>What happens when automatic migration is disabled?</summary>
##### What happens when automatic migration is disabled?
When automatic migration is disabled (`map_legacy_users: false`), Headscale will
only try to match an OIDC account to a Headscale account by `iss` and `sub`.
If there is no match, it will get a _new_ Headscale account – even if there was
a legacy account which _could_ have matched and migrated.
We recommend new Headscale users explicitly disable automatic migration – but it
should otherwise have no effect if every account has a recorded `iss` and `sub`.
When automatic migration is disabled, the `strip_email_domain` setting will have
no effect.
</details>
Special thanks to @micolous for reviewing, proposing and working with us on
these changes.
#### Other OIDC changes
Headscale now uses
[the standard OIDC claims](https://openid.net/specs/openid-connect-core-1_0.html#StandardClaims)
to populate and update user information every time they log in:
| Headscale profile field | OIDC claim | Notes / examples |
| ----------------------- | -------------------- | --------------------------------------------------------------------------------------------------------- |
| email address | `email` | Only used when `"email_verified": true` |
| display name | `name` | eg: `Sam Smith` |
| username | `preferred_username` | Varies depending on IdP and configuration, eg: `ssmith`, `ssmith@idp.example.com`, `\\example.com\ssmith` |
| profile picture | `picture` | URL to a profile picture or avatar |
These should show up nicely in the Tailscale client.
This will also affect the way you
[reference users in policies](https://github.com/juanfont/headscale/pull/2205).
### BREAKING

## 0.23.0 (2024-09-18)
This release was intended to be mainly a code reorganisation and refactoring,
significantly improving the maintainability of the codebase. This should allow
us to improve further and make it easier for the maintainers to keep on top of
the project. However, as you all have noticed, it turned out to become a much
larger, much longer release cycle than anticipated. It has ended up to be a
release with a lot of rewrites and changes to the code base and functionality of
Headscale, cleaning up a lot of technical debt and introducing a lot of
improvements. This does come with some breaking changes,
**Please remember to always back up your database between versions**
#### Here is a short summary of the broad topics of changes:
Code has been organised into modules, reducing use of global variables/objects,
isolating concerns and “putting the right things in the logical place”.
The new
[policy](https://github.com/juanfont/headscale/tree/main/hscontrol/policy) and
[mapper](https://github.com/juanfont/headscale/tree/main/hscontrol/mapper)
package, containing the ACL/Policy logic and the logic for creating the data
served to clients (the network “map”) has been rewritten and improved. This
change has allowed us to finish SSH support and add additional tests throughout
the code to ensure correctness.
The
[“poller”, or streaming logic](https://github.com/juanfont/headscale/blob/main/hscontrol/poll.go)
has been rewritten and instead of keeping track of the latest updates, checking
at a fixed interval, it now uses go channels, implemented in our new
[notifier](https://github.com/juanfont/headscale/tree/main/hscontrol/notifier)
package and it allows us to send updates to connected clients immediately. This
should both improve performance and potential latency before a client picks up
an update.
Headscale now supports sending “delta” updates, thanks to the new mapper and
poller logic, allowing us to only inform nodes about new nodes, changed nodes
and removed nodes. Previously we sent the entire state of the network every time
an update was due.
While we have a pretty good
[test harness](https://github.com/search?q=repo%3Ajuanfont%2Fheadscale+path%3A_test.go&type=code)
for validating our changes, the changes came down to
[284 changed files with 32,316 additions and 24,245 deletions](https://github.com/juanfont/headscale/compare/b01f1f1867136d9b2d7b1392776eb363b482c525...ed78ecd)
and bugs are expected. We need help testing this release. In addition, while we
think the performance should in general be better, there might be regressions in
parts of the platform, particularly where we prioritised correctness over speed.
There are also several bugfixes that has been encountered and fixed as part of
implementing these changes, particularly after improving the test harness as
part of adopting [#1460](https://github.com/juanfont/headscale/pull/1460).
### BREAKING
- Code reorganisation, a lot of code has moved, please review the following PRs
accordingly [#1473](https://github.com/juanfont/headscale/pull/1473)
- Change the structure of database configuration, see
[config-example.yaml](./config-example.yaml) for the new structure.
[#1700](https://github.com/juanfont/headscale/pull/1700)
- Old structure has been remove and the configuration _must_ be converted.
- Adds additional configuration for PostgreSQL for setting max open, idle
connection and idle connection lifetime.
- API: Machine is now Node
[#1553](https://github.com/juanfont/headscale/pull/1553)
- Remove support for older Tailscale clients
[#1611](https://github.com/juanfont/headscale/pull/1611)
- The oldest supported client is 1.42
- Headscale checks that _at least_ one DERP is defined at start
[#1564](https://github.com/juanfont/headscale/pull/1564)
- If no DERP is configured, the server will fail to start, this can be because
it cannot load the DERPMap from file or url.
- Embedded DERP server requires a private key
[#1611](https://github.com/juanfont/headscale/pull/1611)
- Add a filepath entry to
[`derp.server.private_key_path`](https://github.com/juanfont/headscale/blob/b35993981297e18393706b2c963d6db882bba6aa/config-example.yaml#L95)
- Docker images are now built with goreleaser (ko)
[#1716](https://github.com/juanfont/headscale/pull/1716)
[#1763](https://github.com/juanfont/headscale/pull/1763)
- Entrypoint of container image has changed from shell to headscale, require
change from `headscale serve` to `serve`
- `/var/lib/headscale` and `/var/run/headscale` is no longer created
automatically, see [container docs](./docs/running-headscale-container.md)
- Prefixes are now defined per v4 and v6 range.
[#1756](https://github.com/juanfont/headscale/pull/1756)
- `ip_prefixes` option is now `prefixes.v4` and `prefixes.v6`
- `prefixes.allocation` can be set to assign IPs at `sequential` or `random`.
[#1869](https://github.com/juanfont/headscale/pull/1869)
- MagicDNS domains no longer contain usernames []()
- This is in preperation to fix Headscales implementation of tags which
currently does not correctly remove the link between a tagged device and a
user. As tagged devices will not have a user, this will require a change to
the DNS generation, removing the username, see
[#1369](https://github.com/juanfont/headscale/issues/1369) for more
information.
- `use_username_in_magic_dns` can be used to turn this behaviour on again, but
note that this option _will be removed_ when tags are fixed.
- dns.base_domain can no longer be the same as (or part of) server_url.
- This option brings Headscales behaviour in line with Tailscale.
- YAML files are no longer supported for headscale policy.
[#1792](https://github.com/juanfont/headscale/pull/1792)
- HuJSON is now the only supported format for policy.
- DNS configuration has been restructured
[#2034](https://github.com/juanfont/headscale/pull/2034)
- Please review the new [config-example.yaml](./config-example.yaml) for the
new structure.

- Please note that this support should be considered _partially_ implemented
- SSH ACLs status:
- Support `accept` and `check` (SSH can be enabled and used for connecting
and authentication)
- Rejecting connections **are not supported**, meaning that if you enable
SSH, then assume that _all_ `ssh` connections **will be allowed**.
- If you decided to try this feature, please carefully managed permissions
by blocking port `22` with regular ACLs or do _not_ set `--ssh` on your
clients.
- We are currently improving our testing of the SSH ACLs, help us get an
overview by testing and giving feedback.
- This feature should be considered dangerous and it is disabled by default.
Enable by setting `HEADSCALE_EXPERIMENTAL_FEATURE_SSH=1`.

- `/metrics` is now a configurable host:port endpoint:
[#344](https://github.com/juanfont/headscale/pull/344). You must update your
`config.yaml` file to include:

## 0.14.0 (2022-02-24)
**UPCOMING ### BREAKING From the **next\*\* version (`0.15.0`), all machines
will be able to communicate regardless of if they are in the same namespace.
This means that the behaviour currently limited to ACLs will become default.
From version `0.15.0`, all limitation of communications must be done with ACLs.
This is a part of aligning `headscale`'s behaviour with Tailscale's upstream
behaviour.
### BREAKING
- ACLs have been rewritten to align with the bevaviour Tailscale Control Panel
provides. **NOTE:** This is only active if you use ACLs
- Namespaces are now treated as Users
- All machines can communicate with all machines by default
- Tags should now work correctly and adding a host to Headscale should now
reload the rules.
- The documentation have a [fictional example](docs/acls.md) that should cover
some use cases of the ACLs features
