Allow alsa_t to set scheduling priority and send signal to itself When alsactl is running as a daemon with systemd, it sets its process priority to be nice to other processes. When stopping the service, it's signaling to itself that it needs to exit. ---- time->Sun Oct 6 11:59:59 2019 type=AVC msg=audit(1570355999.755:43): avc: denied { setsched } for pid=794 comm="alsactl" scontext=system_u:system_r:alsa_t:s0 tcontext=system_u:system_r:alsa_t:s0 tclass=process permissive=1 ---- time->Sun Oct 6 11:59:59 2019 type=AVC msg=audit(1570355999.755:44): avc: denied { getsched } for pid=794 comm="alsactl" scontext=system_u:system_r:alsa_t:s0 tcontext=system_u:system_r:alsa_t:s0 tclass=process permissive=1 ---- time->Sun Oct 6 12:07:26 2019 type=AVC msg=audit(1570356446.747:292): avc: denied { signal } for pid=3585 comm="alsactl" scontext=system_u:system_r:alsa_t:s0 tcontext=system_u:system_r:alsa_t:s0 tclass=process permissive=1 Signed-off-by: Laurent Bigonville <bigon@bigon.be>
