Description of problem: This happened when typing "top" in a Fedora docker container. Maybe docker should even try reading this file and it's a docker bug, I don't know. SELinux is preventing /var/lib/docker/init/dockerinit-1.2.0 from 'getattr' accesses on the file /proc/kcore. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that dockerinit-1.2.0 should be allowed getattr access on the kcore 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: # grep dockerinit-1.2. /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:docker_t:s0 Target Context system_u:object_r:proc_kcore_t:s0 Target Objects /proc/kcore [ file ] Source dockerinit-1.2.
