Description of problem: Tried to play a track with mpd. SELinux is preventing 6F75747075743A4D792050756C7365 from 'map' accesses on the file 2F6D656D66643A70756C7365617564696F202864656C6574656429. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that 6F75747075743A4D792050756C7365 should be allowed map access on the 2F6D656D66643A70756C7365617564696F202864656C6574656429 file 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 '6F75747075743A4D792050756C7365' --raw | audit2allow -M my-6F75747075743A4D792050756C7365 # semodule -X 300 -i my-6F75747075743A4D792050756C7365.pp Additional Information: Source Context system_u:system_r:mpd_t:s0 Target Context system_u:object_r:mpd_tmpfs_t:s0 Target Objects 2F6D656D66643A70756C7365617564696F202864656C657465 6429 [ file ] Source 6F75747075743A4D792050756C7365 Source Path 6F75747075743A4D792050756C7365 Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.14.1-30.fc28.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 4.16.12-300.fc28.x86_64 #1 SMP Fri May 25 21:13:28 UTC 2018 x86_64 x86_64 Alert Count 5 First Seen 2018-03-19 03:21:33 EDT Last Seen 2018-06-02 20:32:32 EDT Local ID c3c23b44-4c63-42f5-997a-0cf289389609 Raw Audit Messages type=AVC msg=audit(1527985952.282:527): avc: denied { map } for pid=30841 comm=6F75747075743A4D792050756C7365 path=2F6D656D66643A70756C7365617564696F202864656C6574656429 dev="tmpfs" ino=540889 scontext=system_u:system_r:mpd_t:s0 tcontext=system_u:object_r:mpd_tmpfs_t:s0 tclass=file permissive=0 Hash: 6F75747075743A4D792050756C7365,mpd_t,mpd_tmpfs_t,file,map Version-Release number of selected component: selinux-policy-3.14.1-30.fc28.noarch Additional info: component: selinux-policy reporter: libreport-2.9.5 hashmarkername: setroubleshoot kernel: 4.16.12-300.fc28.x86_64 type: libreport
