TYPO3 Core

In the \TYPO3\CMS\Core\Resource\ResourceStorage it is possible to set a the class property $evaluatePermissions.

If this is FALSE no check for filemount boundaries should be performed.

The new feature for read only filemounts has introduced a regression here because the check for this new flag does not respect this setting.

Another problem is that this check in the checkFileActionPermission() method can also fail when the user has multiple filemounts, one which allows writing and one which is read only because it breaks on the first read only filemount.
