Unable to access app data #1327

Describe your problem.

Hi!

We're not really sure if this is a bug or intended behavior, but with KernelSU on WSA app data directories return "Permission denied" whereas Magisk has no such issue.

What we've tried:

Is this intended behavior, a setting we need to change, or a bug? If it's a bug, what information should I provide?

tiann commented 9 months ago

Maybe it is a bug, you can use adb shell and execute su -mm, then ls -al /data/data, can you see any data?

tiann commented 9 months ago

And also, which app do you test?

And also, which app do you test?

App we're developing internally + adb shell (with su)

Will check it tomorrow.

Listing folders (with just su) under /data/data works, but any sort of access to files or directories in actual app data folders results in Permission denied

Do you install Magisk with KernelSU together? Permission denied is werid.

No, both are relatively clean installs of WSA (generated using MagiskOnWSALocal)

androidacy-user commented 9 months ago

su -mm produces no different result. We're currently trying to clean reinstall WSA, just to eliminate any issues on that front.

androidacy-user commented 9 months ago

Weird as hell. After completely uninstalling + reinstalling WSA, the problem resolved itself

What's weird, is there were no selinux denials and permissions should have been okay. We'll just chalk it up to a weird one off problem.

Anyway, thanks for your time!
