Description of problem: Screen suddenly turned black then back to login stage, after entering the password and getting into the system again, this happened. SELinux is preventing abrt-hook-ccpp from using the 'sigchld' accesses on a process. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that abrt-hook-ccpp should be allowed sigchld access on processes labeled kernel_t 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 abrt-hook-ccpp /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:xdm_t:s0-s0:c0.c1023 Target Context system_u:system_r:kernel_t:s0 Target Objects Unknown [ process ] Source abrt-hook-ccpp Source Path abrt-hook-ccpp Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.13.1-135.fc23.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 4.2.0-0.rc1.git3.1.fc23.x86_64 #1 SMP Fri Jul 10 19:49:28 UTC 2015 x86_64 x86_64 Alert Count 2 First Seen 2015-07-13 19:49:23 CST Last Seen 2015-07-13 20:23:50 CST Local ID 5e09d0ea-2472-46b4-b45a-919a4ca9d265 Raw Audit Messages type=AVC msg=audit(1436790230.491:721): avc: denied { sigchld } for pid=5968 comm="abrt-hook-ccpp" scontext=system_u:system_r:xdm_t:s0-s0:c0.c1023 tcontext=system_u:system_r:kernel_t:s0 tclass=process permissive=0 Hash: abrt-hook-ccpp,xdm_t,kernel_t,process,sigchld Version-Release number of selected component: selinux-policy-3.13.1-135.fc23.noarch Additional info: reporter: libreport-2.6.1 hashmarkername: setroubleshoot kernel: 4.2.0-0.rc1.git3.1.fc23.x86_64 type: libreport Potential duplicate: bug 1242467
