Description of problem: SELinux is preventing nm-dispatcher from using the 'signull' accesses on a process. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that nm-dispatcher should be allowed signull access on processes labeled dnssec_trigger_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 nm-dispatcher /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:NetworkManager_t:s0 Target Context system_u:system_r:dnssec_trigger_t:s0 Target Objects Unknown [ process ] Source nm-dispatcher Source Path nm-dispatcher Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.13.1-126.fc22.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Permissive Host Name (removed) Platform Linux (removed) 4.0.4-303.fc22.x86_64 #1 SMP Thu May 28 12:37:06 UTC 2015 x86_64 x86_64 Alert Count 41 First Seen 2015-06-03 17:54:35 PDT Last Seen 2015-06-04 16:18:07 PDT Local ID e415970e-3025-41f8-bb15-d1f7ac426d5f Raw Audit Messages type=AVC msg=audit(1433459887.977:801): avc: denied { signull } for pid=1785 comm="nm-dispatcher" scontext=system_u:system_r:NetworkManager_t:s0 tcontext=system_u:system_r:dnssec_trigger_t:s0 tclass=process permissive=1 Hash: nm-dispatcher,NetworkManager_t,dnssec_trigger_t,process,signull Version-Release number of selected component: selinux-policy-3.13.1-126.fc22.noarch Additional info: reporter: libreport-2.5.1 hashmarkername: setroubleshoot kernel: 4.0.4-303.fc22.x86_64 type: libreport

BZ(1228464) I thought the issue is that NM is not allowed to send the signal to dnssec_trigger_t. Based on the comment, the fix may be wrong.
selinux-policy-3.13.1-128.2.fc22 has been pushed to the Fedora 22 stable repository. If problems still persist, please make note of it in this bug report.
