This file should be labeled user_tmpfs_t in which case nsplugin would have been allowed to use it, But for some reason it got created with the incorrect context. Could you try to upgrade to the latest policy and see if this still happens. I tried an experiment as the unconfined user # mount -t tmpfs_t /dev/shm /mnt # ls -ldZ /mnt/redhat/ drwxrwxrwt root root staff_u:object_r:tmpfs_t:s0 /mnt/redhat/ # touch /mnt/redhat/test # ls -lZ /mnt/redhat/test - -rw-r--r-- root root staff_u:object_r:user_tmpfs_t:s0 /mnt/redhat/test Which is what pulseaudio should have done. Could you check what context pulseaudio is running with # ps -eZ | grep pulse -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iEYEARECAAYFAkk1pdkACgkQrlYvE4MpobNjawCg6EmpLWaQNOK9ndoYgD8GN4TV HG8AoNJIqutO0vFPPa1tjRW+gLk2V9WU =L/DR -----END PGP SIGNATURE----- -- fedora-selinux-list mailing list fedora-selinux-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-selinux-list
