gvfs confinement issues

Thank you Reinhard. Is the convention that these gvfs mounts are "part
of the home directory"? If so then we don't need a separate interface,
let's just extend the existing home interface.

I'd say so. It's files the user has access to. I'd vote for extending the home interface as well, unless somebody has a good counter argument.

This is merged and will be in 2.0.10.

Hello Reinhard, or anyone else affected,

Accepted snapd into xenial-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/snapd/2.0.10 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

Hi Chris,

I've tried a few things and as far as file permissions are concerned it looks good.

I haven't been able to fully test it with my application though because I haven't managed to get g_vfs_get_file_for_uri (GVfs *vfs, const char *uri) working within the sandbox.

Cheers, Reinhard

The verification of the Stable Release Update for snapd has completed successfully and the package has now been released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regressions.

This is fixed in snapd 2.11+16.10 on Ubuntu 16.10 and snapd 2.0.10 on 16.04 LTS.

I still have issues with listing the contents of /run/user/1000/gvfs

Sandboxed apps should be able to list the contents of /run/user/1000/gvfs otherwise it would be impossible to access network storage without already knowing the exact gvfs folder name.

This should list mounted network storage folders, but it fails in the sandbox:

$ ls -l /run/user/1000/gvfs
ls: cannot open directory '/run/user/1000/gvfs': Permission denied

(It should list "afp-volume:host=10.0.1.5,user=reinhard,volume=data")

This works fine:

$ ls -l /run/user/1000/gvfs/afp-volume:host=10.0.1.5,user=reinhard,volume=data
drwxrwxrwx 1 reinhard reinhard 0 May 21 2016 Archive
...

Partially fixed. Still issues with listing the gvfs folder.

Reinhard, can you file a new bug for the directory listing? Thanks!
