Analysing /data with root enabled does not work anymore

[Massedil]

I tried the 5.0-alpha0 on F-Droid and I can't see my files when I try to show /data partition.

It was working with the 3.8.0 version.

Phone: Samsung Galaxy S5
LineageOS : 18.1

Does it work on an older version of diskusage on the same device? I don't have access to rooted devices at this point, so my debugging abilities are limited and the code for capturing this state is removed now.

Yes, it works with the 3.8.0 F-Droid version.

The only bug with 3.8.0 is that 2 same folders (but mounted twice with different names) are counted twice instead of one.

/data/data and /data/user/0 are the same folder.

Here is 3.8.0 on the same device :

Same issue as this ticket and same issue with the old version:

I tried various other entries like "/data/user/0" and it doesn't data either.

The issue with limited access to /data can be worked around by calling magisk su with

  -mm, -M,
  --mount-master                Force run in the global mount namespace

And the app should check for and not follow symlinks (like /data/user/0 -> /data/data)

Patches are welcome.

It seems, the problem is not only the restricted access to /data.
When running the native lib manually, it segfaults immediately, not even printing the "Need directory argument" error.
As I don't know how to debug that, I have to pass the issue to someone who does.
I could however push my change to use --mount-master
