Description Ryu 2022-07-27 13:15:05 UTC
Description of problem:

Selinux gives the following error when I launch the Flatpak version of OBS.

The source process: gdb 
Attempted this access:read 
On this chr_file: nvidiactl


SELinux is preventing gdb from read access on the chr_file nvidiactl.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that gdb should be allowed read access on the nvidiactl chr_file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'gdb' --raw | audit2allow -M my-gdb
# semodule -X 300 -i my-gdb.pp

Hash: gdb,abrt_t,xserver_misc_device_t,chr_file,read

Version-Release number of selected component (if applicable):


How reproducible:

Happens every single time I close OBS (flatpak version)

Steps to Reproduce:
1.  Launch OBS
2.  Close OBS by hitting the X
3.  Program gives a crash warning and then shows a SELinux error

Actual results:

Program crashes after I close it and I get a SELinux error.


Expected results:

Now crash error or SELinux warning.

Additional info:

I noticed this started after I updated some nvidia related flatpak packages along with other flatpak packages.   Here is what I have installed now related to nvidia.  I don't know which one updated though.

nvidia-510-68-02	org.freedesktop.Platform.GL.nvidia-510-68-02		1.4	system
nvidia-515-57	org.freedesktop.Platform.GL.nvidia-515-57		1.4	system


Also, I did flatpak update without using sudo which I found strange that it worked as updates usually always require administrative permissions for RPM and Debian base systems.

Comment 1 Ben Cotton 2023-04-25 17:40:04 UTC
This message is a reminder that Fedora Linux 36 is nearing its end of life.
Fedora will stop maintaining and issuing updates for Fedora Linux 36 on 2023-05-16.
It is Fedora's policy to close all bug reports from releases that are no longer
maintained. At that time this bug will be closed as EOL if it remains open with a
'version' of '36'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, change the 'version' 
to a later Fedora Linux version. Note that the version field may be hidden.
Click the "Show advanced fields" button if you do not see it.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora Linux 36 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora Linux, you are encouraged to change the 'version' to a later version
prior to this bug being closed.

Comment 2 Fedora Release Engineering 2023-08-16 07:05:49 UTC
This bug appears to have been reported against 'rawhide' during the Fedora Linux 39 development cycle.
Changing version to 39.
