So fun fact. Chrome considers a redirect after submitting a form part of
the form actions. Since we redirect to a new protocol (nc://login/).
Causing the form submission to work but the redirect failing hard.

There is no need to log the expcetion of most of the stuff here.
We should properly log them but an exception is excessive.
This moves it to a proper exception which we can catch and then log.
The other exceptions will still be fully logged.

Once 2FA is enforced for a user and they have no 2FA setup yet this will
now prompt them with a setup screen. Given that providers are enabled
that allow setup then.

When a password is reste we should make sure that all users are properly
logged in. Pending states should be cleared. For example a session where
the 2FA code is not entered yet should be cleared.
The token is now removed so the session will be killed the next time
this is checked (within 5 minutes).

If the remember_login_cookie_lifetime is set to 0 this means we do not
want to use remember me at all. In that case we should also not creatae
a remember me cookie and should create a proper temp token.
Further this specifies that is not 0 the remember me time should always
be larger than the session timeout. Because else the behavior is not
really defined.

If a user can't authenticate normally (because they have 2FA that is not
available on their devices for example). The redirect that is generated
should be of the proper format.
This means
1. Include the protocol
2. Include the possible subfolder

In 2f87fb6b45 this header was introduced. The referenced documentation says:
> When delivered with a response from https://example.com/clear, the following header will cause cookies associated with the origin https://example.com to be cleared, as well as cookies on any origin in the same registered domain (e.g. https://www.example.com/ and https://more.subdomains.example.com/).
This also applies if `https://nextcloud.example.com/` sends the `Clear-Site-Data: "cookies"` header.
This is not the behavior we want at this point!
So I removed the deletion of cookies from the header. This has no effect on the logout process as this header is supported only recently and the logout works in old browsers as well.

This adds persistence to the Nextcloud server 2FA logic so that the server
knows which 2FA providers are enabled for a specific user at any time, even
when the provider is not available.
The `IStatefulProvider` interface was added as tagging interface for providers
that are compatible with this new API.

PHPDoc (of the public API) says that this method returns string but it also returns null, which is not allowed in some method calls. This fixes that behaviour and returns an empty string and fixes all code paths that explicitly checked for null to be still compliant.
Found while enabling the strict_typing for lib/private for the PHP7+ migration.

Any `\OCP\Authentication\IApacheBackend` previously had to implement `getLogoutAttribute` which returns a string.
This string is directly injected into the logout `<a>` tag, so returning something like `href="foo"` would result
in `<a href="foo">`.
This is rather error prone and also in Nextcloud 12 broken as the logout entry has been moved with
054e161eb5 inside the navigation manager where one cannot simply inject attributes.
Thus this feature is broken in Nextcloud 12 which effectively leads to the bug described at nextcloud/user_saml#112,
people cannot logout anymore when using SAML using SLO. Basically in case of SAML you have a SLO url which redirects
you to the IdP and properly logs you out there as well.
Instead of monkey patching the Navigation manager I decided to instead change `\OCP\Authentication\IApacheBackend` to
use `\OCP\Authentication\IApacheBackend::getLogoutUrl` instead where it can return a string with the appropriate logout
URL. Since this functionality is only prominently used in the SAML plugin. Any custom app would need a small change but
I'm not aware of any and there's simply no way to fix this properly otherwise.

This implements the basics for the new app-password based authentication flow for our clients.
The current implementation tries to keep it as simple as possible and works the following way:
1. Unauthenticated client opens `/index.php/login/flow`
2. User will be asked whether they want to grant access to the client
3. If accepted the user has the chance to do so using existing App Token or automatically generate an app password.
If the user chooses to use an existing app token then that one will simply be redirected to the `nc://` protocol handler.
While we can improve on that in the future, I think keeping this smaller at the moment has its advantages. Also, in the
near future we have to think about an automatic migration endpoint so there's that anyways :-)
If the user chooses to use the regular login the following happens:
1. A session state token is written to the session
2. User is redirected to the login page
3. If successfully authenticated they will be redirected to a page redirecting to the POST controller
4. The POST controller will check if the CSRF token as well as the state token is correct, if yes the user will be redirected to the `nc://` protocol handler.
This approach is quite simple but also allows to be extended in the future. One could for example allow external websites to consume this authentication endpoint as well.

While the risk is actually quite low because one would already have the user session and could potentially do other havoc it makes sense to throttle here in case of invalid previous password attempts.
Signed-off-by: Lukas Reschke <lukas@statuscode.ch>
This makes the new `@BruteForceProtection` annotation more clever and moves the relevant code into it's own middleware.
Basically you can now set `@BruteForceProtection(action=$key)` as annotation and that will make the controller bruteforce protected. However, the difference to before is that you need to call `$responmse->throttle()` to increase the counter. Before the counter was increased every time which leads to all kind of unexpected problems.

Single user mode basically disables WebDAV, OCS and cron execution. Since
we heavily rely on WebDAV and OCS also in the web UI it's basically useless.
An admin only sees a broken interface and can't even change any settings nor
sees any files. Also sharing is not possible.
As this is at least the case since Nextcloud 9 and we haven't received any
reports for this it seems that this feature is not used at all so I removed it.
The encryption commands now rely on the well tested maintenance mode.

This fixes infinite loops that are caused whenever a user is about to solve a 2FA
challenge, but the provider app is disabled at the same time. Since the session
value usually indicates that the challenge needs to be solved before we grant access
we have to remove that value instead in this special case.
- Updated the config sample to point to log_type='file'
- Renamed the Class for logfile logging to File in namespace 'OC\Log\'.
Changed the occurrences of 'OC\Log\Owncloud' to 'OC\Log\File'.
- Renamed the Class for log:file command to File in namespace 'OC\Core\Command\Log\File'.
Changed registration of the command to use 'OC\Core\Command\Log\File'.
- Changed default Syslog tag to Nextcloud
- Retained backwards compatibility for configs with 'logtype' => 'owncloud'
- Adjusted tests for the new file log.
Closes#490.
Class Throttler implements the bruteforce protection for security actions in
Nextcloud.
It is working by logging invalid login attempts to the database and slowing
down all login attempts from the same subnet. The max delay is 30 seconds and
the starting delay are 200 milliseconds. (after the first failed login)
- remove testResetFormUnsuccessful as it is now splitted up in different test cases
- add testResetFormInvalidToken to check if timestamp and token are present
- add testResetFormInvalidTokenMatch to check if the saved token matches the provided
- add testResetFormExpiredToken to check if expiration detection works
- add testResetFormValidToken to check if detection of valid tokens works
