Description of problem: Happened in normal system use (with avahi service installed/enabled, of course) after 'map' permission was introduced to selinux. SELinux is preventing avahi-daemon from 'map' accesses on the file /var/lib/sss/mc/initgroups. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that avahi-daemon should be allowed map access on the initgroups 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 'avahi-daemon' --raw | audit2allow -M my-avahidaemon # semodule -X 300 -i my-avahidaemon.pp Additional Information: Source Context system_u:system_r:avahi_t:s0 Target Context system_u:object_r:sssd_public_t:s0 Target Objects /var/lib/sss/mc/initgroups [ file ] Source avahi-daemon Source Path avahi-daemon Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages sssd-common-1.15.3-2.fc27.x86_64 Policy RPM selinux-policy-3.13.1-270.fc27.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Permissive Host Name (removed) Platform Linux (removed) 4.13.0-0.rc4.git4.1.fc27.x86_64 #1 SMP Fri Aug 11 15:03:46 UTC 2017 x86_64 x86_64 Alert Count 5 First Seen 2017-08-12 17:17:03 PDT Last Seen 2017-08-14 09:20:49 PDT Local ID fae4c520-74e1-4bfb-a6ea-3ee6ca3bce2f Raw Audit Messages type=AVC msg=audit(1502727649.397:106): avc: denied { map } for pid=1043 comm="avahi-daemon" path="/var/lib/sss/mc/initgroups" dev="dm-2" ino=397741 scontext=system_u:system_r:avahi_t:s0 tcontext=system_u:object_r:sssd_public_t:s0 tclass=file permissive=1 Hash: avahi-daemon,avahi_t,sssd_public_t,file,map Version-Release number of selected component: selinux-policy-3.13.1-270.fc27.noarch Additional info: component: selinux-policy reporter: libreport-2.9.1 hashmarkername: setroubleshoot kernel: 4.13.0-0.rc4.git4.1.fc27.x86_64 type: libreport
