Description of problem: Probably called by rpm SELinux is preventing procmail from using the 'dac_override' capabilities. ***** Plugin dac_override (91.4 confidence) suggests ********************** If you want to help identify if domain needs this access or you have a file with the wrong permissions on your system Then turn on full auditing to get path information about the offending file and generate the error again. Do Turn on full auditing # auditctl -w /etc/shadow -p w Try to recreate AVC. Then execute # ausearch -m avc -ts recent If you see PATH record check ownership/permissions on file, and fix it, otherwise report as a bugzilla. ***** Plugin catchall (9.59 confidence) suggests ************************** If you believe that procmail should have the dac_override capability 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 'procmail' --raw | audit2allow -M my-procmail # semodule -X 300 -i my-procmail.pp Additional Information: Source Context system_u:system_r:procmail_t:s0 Target Context system_u:system_r:procmail_t:s0 Target Objects Unknown [ capability ] Source procmail Source Path procmail Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages Policy RPM <Unknown> Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 4.16.7-100.fc26.i686+PAE #1 SMP Wed May 2 22:19:22 UTC 2018 i686 i686 Alert Count 4 First Seen 2018-05-16 08:38:18 CEST Last Seen 2018-05-18 06:30:09 CEST Local ID b1e8469a-33ad-4bb7-8669-07a2db05f0c6 Raw Audit Messages type=AVC msg=audit(1526617809.818:285): avc: denied { dac_override } for pid=6700 comm="procmail" capability=1 scontext=system_u:system_r:procmail_t:s0 tcontext=system_u:system_r:procmail_t:s0 tclass=capability permissive=0 Hash: procmail,procmail_t,procmail_t,capability,dac_override Additional info: component: selinux-policy reporter: libreport-2.9.5 hashmarkername: setroubleshoot kernel: 4.16.7-100.fc26.i686+PAE type: libreport
