Description of problem: SELinux is preventing cat from 'read' accesses on the file dmesg_restrict. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that cat should be allowed read access on the dmesg_restrict 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 cat /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:abrt_t:s0-s0:c0.c1023 Target Context system_u:object_r:proc_security_t:s0 Target Objects dmesg_restrict [ file ] Source cat Source Path cat Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.13.1-105.19.fc21.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 4.0.7-200.fc21.x86_64 #1 SMP Mon Jun 29 22:11:52 UTC 2015 x86_64 x86_64 Alert Count 1 First Seen 2015-07-07 20:42:13 PDT Last Seen 2015-07-07 20:42:13 PDT Local ID 0f6c9d9e-8fc0-4670-aa69-8a55a8773fb4 Raw Audit Messages type=AVC msg=audit(1436326933.966:1715): avc: denied { read } for pid=29018 comm="cat" name="dmesg_restrict" dev="proc" ino=103371 scontext=system_u:system_r:abrt_t:s0-s0:c0.c1023 tcontext=system_u:object_r:proc_security_t:s0 tclass=file permissive=0 Hash: cat,abrt_t,proc_security_t,file,read Version-Release number of selected component: selinux-policy-3.13.1-105.19.fc21.noarch Additional info: reporter: libreport-2.3.0 hashmarkername: setroubleshoot kernel: 4.0.7-200.fc21.x86_64 type: libreport
