This AVC causes postfix to refuse to start when running in enforcing mode.

Description of problem: systemd start postfix SELinux is preventing postalias from 'read' accesses on the lnk_file log. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that postalias should be allowed read access on the log 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 'postalias' --raw | audit2allow -M my-postalias # semodule -X 300 -i my-postalias.pp Additional Information: Source Context system_u:system_r:postfix_master_t:s0 Target Context system_u:object_r:tmpfs_t:s0 Target Objects log [ lnk_file ] Source postalias Source Path postalias Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.13.1-222.fc25.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Permissive Host Name (removed) Platform Linux (removed) 4.8.6-300.fc25.x86_64 #1 SMP Tue Nov 1 12:36:38 UTC 2016 x86_64 x86_64 Alert Count 498 First Seen 2016-11-01 02:44:20 PDT Last Seen 2016-11-14 17:07:06 PST Local ID 898f6890-49d2-4a84-a920-6af5ee04ea1d Raw Audit Messages type=AVC msg=audit(1479172026.404:329): avc: denied { read } for pid=3868 comm="postfix" name="log" dev="tmpfs" ino=96035 scontext=system_u:system_r:postfix_master_t:s0 tcontext=system_u:object_r:tmpfs_t:s0 tclass=lnk_file permissive=1 Hash: postalias,postfix_master_t,tmpfs_t,lnk_file,read Version-Release number of selected component: selinux-policy-3.13.1-222.fc25.noarch Additional info: reporter: libreport-2.8.0 hashmarkername: setroubleshoot kernel: 4.8.6-300.fc25.x86_64 type: libreport
