As an additional security hardening it's sensible to serve these files with a Content-Disposition of 'attachment'. Currently they are served 'inline' and get a "secure mimetype" assigned in case of potential dangerous files.
To test this change ensure that:
- [ ] Syncing with the Desktop client still works
- [ ] Syncing with the Android client still works
- [ ] Syncing with the iOS client still works
I verified that the 1.8 OS X and iOS client still work with this change.
Reasoning:
- a WebDAV server is not required to implement locking support
- WebDAV Locking is know to break the sync algorithm
- the current lock implementation is known to be broken (locks are not moved if a file is moved, locks on shared files don't work)
- VObject fixes for Sabre\VObject 3.3
- Remove VObject property workarounds
- Added prefetching for tags in sabre tags plugin
- Moved oc_properties logic to separate PropertyStorage backend (WIP)
- Fixed Sabre connector namespaces
- Improved files plugin to handle props on-demand
- Moved allowed props from server class to files plugin
- Fixed tags caching for files that are known to have no tags
(less queries)
- Added/fixed unit tests for Sabre FilesPlugin, TagsPlugin
- Replace OC\Connector\Sabre\Request with direct call to
httpRequest->setUrl()
- Fix exception detection in DAV client when using Sabre\DAV\Client
- Added setETag() on Node instead of using the static FileSystem
- Also preload tags/props when depth is infinity
This changeset removes the static class `OC_Request` and moves the functions either into `IRequest` which is accessible via `\OC::$server::->getRequest()` or into a separated `TrustedDomainHelper` class for some helper methods which should not be publicly exposed.
This changes only internal methods and nothing on the public API. Some public functions in `util.php` have been deprecated though in favour of the new non-static functions.
Unfortunately some part of this code uses things like `__DIR__` and thus is not completely unit-testable. Where tests where possible they ahve been added though.
Fixes https://github.com/owncloud/core/issues/13976 which was requested in https://github.com/owncloud/core/pull/13973#issuecomment-73492969
\Sabre\DAV\Auth\Backend\AbstractBasic::authenticate was only calling \OC_Connector_Sabre_Auth::validateUserPass when the response of \Sabre\HTTP\BasicAuth::getUserPass was not null.
However, there is a case where the value can be null and the user could be authenticated anyways: The authentication via ownCloud web-interface and then accessing WebDAV resources. This was not possible anymore with this patch because it never reached the code path in this scenario.
This patchs allows authenticating with a session without isDavAuthenticated value stored (this is for ugly WebDAV clients that send the cookie in any case) and thus the functionality should work again.
To test this go to the admin settings and test if the WebDAV check works fine. Furthermore all the usual stuff (WebDAV / Shibboleth / etc...) needs testing as well.
