[Security] Various CS + doc fixes
[Security] Exception when authentication failure/success handlers do not return a response
[Security] Add authors + fix docblock
This is not a problem with Symfony, but when using the component
standalone (Silex for instance), the context listener might be
instantiated even if the firewall does not need to be fired. In that
case, the handle() method is not called, but the response listener is
called, which means that en empty token is stored in the session.
For Silex, it means that when authenticated, if you visit a 404 page,
you would be disconnected automatically.

License of the code: MIT
If there are two firewalls (eg. main and admin), calling an protected admin url
will direct you to the login form of the admin. If I ignore this and go to the login
form of the main firewall directly I will end up being redirected to the stored
admin target url, which will lead me to the admin login form again.

Doesn't this make sense or did this slip through? Or is there something missing?
If there are two firewalls (eg. main and admin), calling an protected admin url
will direct you to the login form of the admin. If I ignore this and go to the login
form of the main firewall directly I will end up being redirected to the stored

@fabpot could you review it ?

My comments:
* `ServerBag` represents what we have in the `$_SERVER` global variables. As such, the code should be moved to the `getHeaders()` method instead like the other tweaks we do for the HTTP headers.
* A comment must be added explaining why this is needed and the configuration the user must have to make it work (then remove the Github URLs).
* The code should only be executed when `PHP_AUTH_USER` is not available (to not have any overhead when not needed).

A quick note on that .htaccess/apache configuration required, if adding to the Symfony SE htaccess file, then it will need to look like this:
```
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ app.php [QSA,L]
</IfModule>
```
NOTE: No **,L** in the Authorization Rewrite as in the original example - it prevents the front controller rewrite from happening

your PR is fine for sure and I don't want to interfere, just wanted to mention that part of the bug hunt day of Symfony I had a go at this PR as an "exercise" but just saw later on that you already fixed the problem, so you can ignore my pushes

[Security] Implement support for CSRF tokens in logout URL's
```
Bug fix: no
Feature addition: yes
Backwards compatibility break: no
Symfony2 tests pass: yes
Fixes the following tickets: -
Todo: -
```
[](http://travis-ci.org/jmikola/symfony)
This derived from #3006 but properly targeting on the master branch.
This exposes new configuration options to the logout listener to enable CSRF protection, as already exists for the form login listener. The individual commits and their extended messages should suffice for explaining the logical changes of the PR.
In addition to changing LogoutListener, I also created a templating helper to generate logout URL's, which includes a CSRF token if necessary. This may or may not using routing, depending on how the listener is configured since both route names or hard-coded paths are valid options.
Additionally, I added unit tests for LogoutListener and functional tests for both CSRF-enabled form logins and the new logout listener work.
Kudo's to @henrikbjorn for taking the time to document CSRF validation for form login listeners (see [here](http://henrik.bjrnskov.dk/symfony2-cross-site-request-forgery/)). The [Logout CSRF Protection](http://www.yiiframework.com/wiki/190/logout-csrf-protection/) article on the Yii Framework wiki was also helpful in drafting this.

@schmittjoh: Please let me know your thoughts on the last commit. I think it would be overkill to add support for another handler service and/or error page just for logout exceptions.
Perhaps as an alternative, we might just want to consider an invalid CSRF token on logout imply a false return value for `LogoutListener::requiresLogout()`. That would sacrifice the ability to handle the error separately (which a 403 response allows us), although we could still add logging (currently done in ExceptionListener).

After rebasing, my merge commits disappeared. Is this normal?
---------------------------------------------------------------------------
by stof at 2012-02-15T00:15:07Z
Are you sure they disappeared ? Diverging from the remote branch is logical (you rewrote the history and so changed the commit id) but are you sure it does not have the commits on top of master ? Try ``git log master..logout-scrf``
If your commut are there, you simply need to force the push for the logout-csrf branch (take care to push only this branch during the force push to avoid messing all others as git won't warn you when asking to force)
---------------------------------------------------------------------------
by stof at 2012-02-15T00:17:09Z
ah sorry, you talked only about the merge commit. Yeah it is normal. When reapplying your commits on top of master, the merge commit are not kept as you are reapplying the changes linearly on top of the other branch (and deleting the merge commit was the reason why @fabpot asked you to rebase instead of merging btw)
---------------------------------------------------------------------------
by jmikola at 2012-02-15T00:18:00Z
The merge commits are not present in `git log master..logout-csrf`. Perhaps it used those merge commits when rebasing, as there were definitely conflicts resolved when I originally merged in symfony/master (@fabpot had made his own changes to LogoutListener).
I'll force-push the changes to my PR brange. IIRC, GitHub is smart enough to preserve inline diff comments, provided they were made through the PR and not on the original commits.
---------------------------------------------------------------------------
by jmikola at 2012-02-15T00:19:38Z
That worked well. In the future, I think I'll stick to merging upstream in and then rebasing afterwards. Resolving conflicts is much easier during a merge than interactive rebase.
---------------------------------------------------------------------------

@fabpot @schmittjoh: Is there anything else I can do for this PR? I believe the exception was the only outstanding question (see: [this comment](https://github.com/symfony/symfony/pull/3007#issuecomment-3835716)).
On the advice of @schmittjoh, this commit adds a LogoutException class for use by LogoutListener if the CSRF token is invalid.
The handling in the Security component's ExceptionListener is modeled after AccessDeniedException, which gets wrapped in an AccessDeniedHttpException in the absence of handler service or error page (I didn't think it was appropriate to re-use those for LogoutException).
This adds several new options to the logout listener, modeled after the form_login listener:
* csrf_parameter
* intention
* csrf_provider
The "csrf_parameter" and "intention" have default values if omitted. By default, "csrf_provider" is empty and CSRF validation is disabled in LogoutListener (preserving BC). If a service ID is given for "csrf_provider", CSRF validation will be enabled. Invalid tokens will result in an InvalidCsrfTokenException being thrown before any logout handlers are invoked.

Well I'm sure it is never intended by a developer to be redirected to the login page after logging in but it could be possible that the controller which displays the login form handles this case, so my change would break it.
