Description of problem: SELinux policy defines following file context pattern: # semanage fcontext -l | grep minidlna_exec_t /usr/sbin/minidlna regular file system_u:object_r:minidlna_exec_t:s0 # but the minidlna package does not bring such a file. The package brings a /usr/sbin/minidlnad file which is labeled bin_t, but it should be labeled minidlna_exec_t. Version-Release number of selected component (if applicable): minidlna-1.2.1-1.fc27.x86_64 selinux-policy-3.13.1-283.26.fc27.noarch selinux-policy-targeted-3.13.1-283.26.fc27.noarch How reproducible: * always Steps to Reproduce: 1. get a Fedora 27 machine (targeted policy is active) 2. install RPMfusion free repositories 3. install the minidlna package 4. start the minidlna service 5. search for SELinux denials Actual results: * the minidlna service runs as unconfined_service_t Expected results: * the minidlna service runs as minidlna_t and it does not trigger SELinux denials in default configuration Additional info: * if /usr/sbin/minidlnad is labeled minidlna_exec_t, then following SELinux denials appear in permissive mode: ---- time->Sun Mar 11 06:51:54 2018 type=AVC msg=audit(1520765514.286:329): avc: denied { read } for pid=2051 comm="minidlnad" name="cpu" dev="sysfs" ino=33 scontext=system_u:system_r:minidlna_t:s0 tcontext=system_u:object_r:sysfs_t:s0 tclass=dir permissive=1 ---- time->Sun Mar 11 06:51:54 2018 type=AVC msg=audit(1520765514.286:330): avc: denied { read } for pid=2051 comm="minidlnad" name="meminfo" dev="sysfs" ino=660 scontext=system_u:system_r:minidlna_t:s0 tcontext=system_u:object_r:sysfs_t:s0 tclass=file permissive=1 ---- time->Sun Mar 11 06:51:54 2018 type=AVC msg=audit(1520765514.286:331): avc: denied { open } for pid=2051 comm="minidlnad" path="/sys/devices/system/node/node0/meminfo" dev="sysfs" ino=660 scontext=system_u:system_r:minidlna_t:s0 tcontext=system_u:object_r:sysfs_t:s0 tclass=file permissive=1 ---- time->Sun Mar 11 06:51:54 2018 type=AVC msg=audit(1520765514.286:332): avc: denied { getattr } for pid=2051 comm="minidlnad" path="/sys/devices/system/node/node0/meminfo" dev="sysfs" ino=660 scontext=system_u:system_r:minidlna_t:s0 tcontext=system_u:object_r:sysfs_t:s0 tclass=file permissive=1 ---- time->Sun Mar 11 06:51:54 2018 type=AVC msg=audit(1520765514.288:333): avc: denied { read } for pid=2051 comm="minidlnad" name="unix" dev="proc" ino=4026532057 scontext=system_u:system_r:minidlna_t:s0 tcontext=system_u:object_r:proc_net_t:s0 tclass=file permissive=1 ---- time->Sun Mar 11 06:51:54 2018 type=AVC msg=audit(1520765514.289:334): avc: denied { create } for pid=2051 comm="minidlnad" scontext=system_u:system_r:minidlna_t:s0 tcontext=system_u:system_r:minidlna_t:s0 tclass=unix_dgram_socket permissive=1 ---- time->Sun Mar 11 06:51:54 2018 type=AVC msg=audit(1520765514.289:335): avc: denied { ioctl } for pid=2051 comm="minidlnad" path="socket:[25584]" dev="sockfs" ino=25584 ioctlcmd=0x8933 scontext=system_u:system_r:minidlna_t:s0 tcontext=system_u:system_r:minidlna_t:s0 tclass=unix_dgram_socket permissive=1 ----
