This PR implements the base foundation of the code signing and integrity check. In this PR implemented is the signing and verification logic, as well as commands to sign single apps or the core repository.
Furthermore, there is a basic implementation to display problems with the code integrity on the update screen.
Code signing basically happens the following way:
- There is a ownCloud Root Certificate authority stored `resources/codesigning/root.crt` (in this PR I also ship the private key which we obviously need to change before a release 😉). This certificate is not intended to be used for signing directly and only is used to sign new certificates.
- Using the `integrity:sign-core` and `integrity:sign-app` commands developers can sign either the core release or a single app. The core release needs to be signed with a certificate that has a CN of `core`, apps need to be signed with a certificate that either has a CN of `core` (shipped apps!) or the AppID.
- The command generates a signature.json file of the following format:
```json

`hashes` is an array of all files in the folder with their corresponding SHA512 hashes (this is actually quite cheap to calculate), the `certificate` is the certificate used for signing. It has to be issued by the ownCloud Root Authority and it's CN needs to be permitted to perform the required action. The `signature` is then a signature of the `hashes` which can be verified using the `certificate`.
Steps to do in other PRs, this is already a quite huge one:
- Add nag screen in case the code check fails to ensure that administrators are aware of this.
- Add code verification also to OCC upgrade and unify display code more.
- Add enforced code verification to apps shipped from the appstore with a level of "official"
- Add enfocrced code verification to apps shipped from the appstore that were already signed in a previous release
- Add some developer documentation on how devs can request their own certificate
- Check when installing ownCloud
- Add support for CRLs to allow revoking certificates
**Note:** The upgrade checks are only run when the instance has a defined release channel of `stable` (defined in `version.php`). If you want to test this, you need to change the channel thus and then generate the core signature:
```
➜ master git:(add-integrity-checker) ✗ ./occ integrity:sign-core --privateKey=resources/codesigning/core.key --certificate=resources/codesigning/core.crt
Successfully signed "core"
```
Then increase the version and you should see something like the following:
As you can see a failed code check will not prevent the further update. It will instead just be a notice to the admin. In a next step we will add some nag screen.
For packaging stable releases this requires the following additional steps as a last action before zipping:
1. Run `./occ integrity:sign-core` once
2. Run `./occ integrity:sign-app` _for each_ app. However, this can be simply automated using a simple foreach on the apps folder.
Adding group Db to federation tests and ldap tests
Add group DB to Test_UrlGenerator
Adding group DB to trashbin and versions tests
Adding group DB to Test_Util_CheckServer for pg
This is necessary to categorize unit test and avoid duplicate test case execution - it also allows us to closely review unit test implementations to identify unnecessary db calls.
Currently the `getPath` methods returned `NULL` in case when a file with the specified ID does not exist. This however mandates that developers are checking for the `NULL` case and if they do not the door for bugs with all kind of impact is widely opened.
This is especially harmful if used in context with Views where the final result is limited based on the result of `getPath`, if `getPath` returns `NULL` PHP type juggles this to an empty string resulting in all possible kind of bugs.
While one could argue that this is a misusage of the API the fact is that it is very often misused and an exception will trigger an immediate stop of execution as well as log this behaviour and show a pretty error page.
I also adjusted some usages where I believe that we need to catch these errors, in most cases this is though simply an error that should hard-fail.
IDN is not installed on all machines making the unit test execution fail on those without. Let's make IDN thus a pre-requirement for the text execution.
Fix regression that makes PROPPATCH of mtime work like it did in OC <=
8.0.
The PROPPATCH must be done on the "lastmodified" property.
The "getlastmodified" now return 403 again.
If folder1 is shared to user2 and user3. And folder1/folder2 is shared
to user4 and user5 then getting all the users with access to
folder1/folder2 should only list user2 and user 3 once.
Previously this was done twice since we request the info two times.
This fix makes sure that we only append unique results to the array.
* Added test
`\OCP\IRequest::getScriptName` will also return the directory, so if ownCloud is installed in a subfolder such as `owncloud/` it will resolve to `/owncloud/ocs/v2.php`. This made this check fail and also made it return invalid status codes.
Some folders might have an extension like "test.conf".
This fix prevents to overwrite the folder's mime type with another mime
type while running the mimetype repair step.
Fixes#5251
If we perform a move we need to make sure first that the source can be
deleted. Else the dest might be cleared but the move will fail later.
* Added unit tests
Eventually we need more and better checking here.
use default config for swift primary storage test config
allow testsuite to complete
fix timeout, script cleanup, enable debug for now
use btrfs loopback device, requires privileged container and absolute path
throw exception when storage has problems
debug by echo ...
sleep more, more debug
Group shares usually have subshare entries for every user. In some
situations it can happen that the user was removed from the group but
the subshare entries still exist.
This fix makes sure that such subshare entries are not returned any more
as the user isn't in the group any more.
It is already not allowed to share a folder containing mount points /
incoming shares.
This fixes an issue that made it possible to bypass the check by moving
the incoming share mount point into an existing outgoing share folder.

If a file/folder is reshared we should not blindly copy the expiration
date of the parent share. User/Group shares do not have expiration dates
currently, and thus this is always set to null.
Fixes#19119
* Added testcase
There is the case where OCs IDs might become outdated such as it has been with the calendar and contacts app which refer to the old dummy entry. This means that users with the old OCS id can't update updates as well will receive invalid state flags. (e.g. "experimental" instead of "approved")
To allow instances to properly update the applications in the future we need to migrate the OCS IDs for now manually.
