Description of problem: PID that created the error is a spamd child process. ausearch came up with: time->Mon Dec 31 00:07:58 2018 type=AVC msg=audit(1546232878.601:102892): avc: denied { dac_override } for pid=13620 comm="spamd" capability=1 scontext=system_u:system_r:spamd_t:s0 tcontext=system_u:system_r:spamd_t:s0 tclass=capability permissive=0 SELinux is preventing spamd 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 spamd 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 'spamd' --raw | audit2allow -M my-spamd # semodule -X 300 -i my-spamd.pp Additional Information: Source Context system_u:system_r:spamd_t:s0 Target Context system_u:system_r:spamd_t:s0 Target Objects Unknown [ capability ] Source spamd Source Path spamd Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.14.2-44.fc29.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 4.19.8-300.fc29.x86_64 #1 SMP Mon Dec 10 15:23:11 UTC 2018 x86_64 x86_64 Alert Count 1 First Seen 2018-12-31 00:07:58 EST Last Seen 2018-12-31 00:07:58 EST Local ID 478cfaa8-7342-4866-a20c-4b4d5e52440f Raw Audit Messages type=AVC msg=audit(1546232878.601:102892): avc: denied { dac_override } for pid=13620 comm="spamd" capability=1 scontext=system_u:system_r:spamd_t:s0 tcontext=system_u:system_r:spamd_t:s0 tclass=capability permissive=0 Hash: spamd,spamd_t,spamd_t,capability,dac_override Version-Release number of selected component: selinux-policy-3.14.2-44.fc29.noarch Additional info: component: selinux-policy reporter: libreport-2.9.7 hashmarkername: setroubleshoot kernel: 4.19.8-300.fc29.x86_64 type: libreport
