Hello, Is there any configuration change needed to trigger this denial? Can you set your system to permissive mode and try again to collect all denials? setenforce 0 Hi, I'm not aware of any changes apart from regular dnf updates. I started reporting these as I'm getting some unrelated AVC denials due to installing of an antivirus (this is my company laptop). I was mostly ignoring them before.. I'll try with permissive settings. It happened again in Permissive mode:
SELinux is preventing switcheroo-cont from getattr access on the filesystem /dev/shm.
***** Plugin catchall (100. confidence) suggests **************************
If you believe that switcheroo-cont should be allowed getattr access on the shm filesystem 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 'switcheroo-cont' --raw | audit2allow -M my-switcheroocont
# semodule -X 300 -i my-switcheroocont.pp
