CardDAV and CalDAV stop working with E2EE enabled. about end_to_end_encryption

[schiessle]

Thanks, this is probably caused by the sabredav plugins implemented here. I will look into it.

@schiessle I have the same problem, but also with your PR :/

[schiessle]

@mannp we could just test it successfully with some small changes. I merged it now into master. Please reopen the issue (or create a new one) if you still experience any problem.

[schiessle]

@mannp this should solve the issue: #4 Maybe you can give it a try and report back? Thanks a lot!

[mannp]

@schiessle thanks for the update.

I am using a git version of the plugin and have done a new git pull for your changes, but sill lose access with E2EE enabled.

Am I picking up all the changes? Are they solely in an updated plugin?

I have done the git pull and rebooted my server just in case and still have no access via CardDav or Caldav; getting 404.

I also lose connection on my android phone through davdroid.

[schiessle]

@mannp you need to checkout the branch with the fix: git checkout only-files

[mannp]

@schiessle Oops! So, with initial tests on that branch I am able to sync both Dav's on the mac and android devices.

I will take a further look tomorrow, as I haven't configured e2ee yet, but initial tests look good 👍

[schiessle]

Great, thanks for testing @mannp !

@schiessle Hi there. So I have had no issues with CalDAV and CardDav syncing now, but I now cannot upload files from the latest android app to my server, they just error out.

I also cannot setup E2EE which might be related to not being able to upload files.

Happy to create a new issue if these are unrelated to CardDav and CalDAV.

The errors in my log are as follows;

end_to_end_encryption | Can't create public key: could not sign the CSR, please make sure to submit a valid CSR
-- | --

PHP | openssl_csr_sign(): cannot get CSR from parameter 1 at /config/www/nextcloud/apps/end_to_end_encryption/lib/SignatureHandler.php#60
-- | --

webdav | OCA\DAV\Connector\Sabre\Exception\InvalidPath: Dot files are not allowed
-- | --

[schiessle]

At first sight I would say that this is not related, creating a public key should be completely independent from the DAV request. Looks like the Android client sends a wrong CSR... @tobiasKaminsky what do you think?

[schiessle]

@mannp just to double check, if you switch back to the master branch it works again?

[tobiasKaminsky]

@schiessle the first error message is related to E2E, but the third one "InvalidPath: Dot files are not allowed"....?

[schiessle]

@tobiasKaminsky maybe you can try the pull request as well? #4? Then we can debug it together...Thanks!

[mannp]

@schiessle Thats a good question as I hadn't bothered to setup E2EE before as I didn't want to sacrifice the DAV's to test it.

I will revert back to master and try to setup directly, but it would be good if @tobiasKaminsky has chance to test too, as the interoperability is pretty critical 👍 and perhaps not best left to my level of testing :)

[ConorIA]

I can confirm that my Android app hangs at "Generating new keys..." when the #4 branch is active on the server.

[mannp]

@schiessle It's not particularly clear to me but it seems the csr error is present in both branches.

[mannp]

Did this one get resolved? or is in progress, or not being looked at :) ?

No updates to the code, so I am assuming its on hold?

Thanks in advance
