Red Hat Bugzilla – Bug 1278983
SELinux is preventing SetroubleshootF from 'write' accesses on the directory /var/tmp.
Last modified: 2016-02-16 22:50:46 EST
Description of problem: This happened after attempting to run restorecon for a problem with the provided button in SELinux Alert Browser. The 'fixes' were needed after updating my Fedora 22 system to Fedora 23. There were two other related problems. I will mark them as related once I have all the numbers. SELinux is preventing SetroubleshootF from 'write' accesses on the directory /var/tmp. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that SetroubleshootF should be allowed write access on the tmp directory 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 SetroubleshootF /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:setroubleshoot_fixit_t:s0-s0:c0. c1023 Target Context system_u:object_r:tmp_t:s0 Target Objects /var/tmp [ dir ] Source SetroubleshootF Source Path SetroubleshootF Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages filesystem-3.2-35.fc23.x86_64 Policy RPM selinux-policy-3.13.1-152.fc23.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 4.2.5-300.fc23.x86_64 #1 SMP Tue Oct 27 04:29:56 UTC 2015 x86_64 x86_64 Alert Count 6 First Seen 2015-11-06 22:36:52 GMT Last Seen 2015-11-06 22:36:52 GMT Local ID 9e1ef59e-fcba-41f2-89bb-e87d6cb33ea6 Raw Audit Messages type=AVC msg=audit(1446849412.408:817): avc: denied { write } for pid=12161 comm="SetroubleshootF" name="tmp" dev="sda2" ino=130145 scontext=system_u:system_r:setroubleshoot_fixit_t:s0-s0:c0.c1023 tcontext=system_u:object_r:tmp_t:s0 tclass=dir permissive=0 Hash: SetroubleshootF,setroubleshoot_fixit_t,tmp_t,dir,write Version-Release number of selected component: selinux-policy-3.13.1-152.fc23.noarch Additional info: reporter: libreport-2.6.3 hashmarkername: setroubleshoot kernel: 4.2.5-300.fc23.x86_64 type: libreport

Until there's refactored code in sealert it would need to use similar fix as 14ce26603c60b9cf8fb98b0be0f2209cedf7bc45 to allow setroubleshoot_fixit_t to create and manage temp files.
Created attachment 1123024 [details] proposed patch I've not tested this patch yet but it should work. Still I will try to refactor the sealert code.
