Description of problem: Cockpit places a symlink in /etc/issue.d/cockpit.issue to /run/cockpit/motd which is intended to show the admin console URL on the non-graphical login console of the system. The selinux policy is now denying agetty the ability to read this file, which it was allowing properly in the past. SELinux is preventing agetty from 'read' accesses on the lnk_file motd. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that agetty should be allowed read access on the motd lnk_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 'agetty' --raw | audit2allow -M my-agetty # semodule -X 300 -i my-agetty.pp Additional Information: Source Context system_u:system_r:getty_t:s0-s0:c0.c1023 Target Context system_u:object_r:cockpit_var_run_t:s0 Target Objects motd [ lnk_file ] Source agetty Source Path agetty Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.14.2-35.fc29.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 4.18.7-300.fc29.x86_64 #1 SMP Mon Sep 10 15:37:17 UTC 2018 x86_64 x86_64 Alert Count 1 First Seen 2018-09-20 08:47:18 EDT Last Seen 2018-09-20 08:47:18 EDT Local ID 2bae4d9c-054a-48a9-be58-6877cdf70a71 Raw Audit Messages type=AVC msg=audit(1537447638.112:320): avc: denied { read } for pid=3707 comm="agetty" name="motd" dev="tmpfs" ino=30806 scontext=system_u:system_r:getty_t:s0-s0:c0.c1023 tcontext=system_u:object_r:cockpit_var_run_t:s0 tclass=lnk_file permissive=0 Hash: agetty,getty_t,cockpit_var_run_t,lnk_file,read Version-Release number of selected component: selinux-policy-3.14.2-35.fc29.noarch Additional info: component: selinux-policy reporter: libreport-2.9.5 hashmarkername: setroubleshoot kernel: 4.18.7-300.fc29.x86_64 type: libreport
