Did you run in permissive mode? Any idea how pulseaudio file got mislabeled? What other tools were you running? The only other thing that uses pulse and doesn't come from the Fedora repositories I use here is Skype. I have not run in permissive mode. I also run (installed from the repositories) pactl and pavucontrol. So I should just relabel the file and close the bug? Well I would love to know how it happened. It is a file in /dev/shm and I have no idea which domain creating it would create it as tmpfs_t rather then user_tmpfs_t. skype should run under the unconfined_t domain and thus create it as user_tmpfs_t. Is there any more debug information I could provide to help solve this problem? *** Bug 822273 has been marked as a duplicate of this bug. *** What does # ls -Z /dev/shm/ -r--------. elad elad unconfined_u:object_r:user_tmpfs_t:s0 pulse-shm-2066826072 -r--------. gdm gdm system_u:object_r:user_tmpfs_t:s0 pulse-shm-2239420499 -r--------. gdm gdm system_u:object_r:user_tmpfs_t:s0 pulse-shm-3123853139 -r--------. gdm gdm system_u:object_r:user_tmpfs_t:s0 pulse-shm-3301271153 -r--------. elad elad unconfined_u:object_r:user_tmpfs_t:s0 pulse-shm-3961955622 -r--------. elad elad unconfined_u:object_r:user_tmpfs_t:s0 pulse-shm-407317724 -r--------. elad elad unconfined_u:object_r:user_tmpfs_t:s0 pulse-shm-912411733 -r--------. elad elad unconfined_u:object_r:user_tmpfs_t:s0 pulse-shm-91519574 Miroslav maybe we should just don't audit this, since it seems to be a race condition, and I have seen it over the years but we never see a tmpfs_t file in the directory. I agree. I have been trying to reproduce it but without success.
