Description of problem: Not sure what caused this SELinux is preventing winbindd from using the 'signull' accesses on a process. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that winbindd should be allowed signull access on processes labeled systemd_hostnamed_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: # ausearch -c 'winbindd' --raw | audit2allow -M my-winbindd # semodule -X 300 -i my-winbindd.pp Additional Information: Source Context system_u:system_r:winbind_t:s0 Target Context system_u:system_r:systemd_hostnamed_t:s0 Target Objects Unknown [ process ] Source winbindd Source Path winbindd Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.14.1-44.fc28.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 4.18.13-200.fc28.x86_64 #1 SMP Wed Oct 10 17:29:59 UTC 2018 x86_64 x86_64 Alert Count 1 First Seen 2018-10-22 10:50:25 EDT Last Seen 2018-10-22 10:50:25 EDT Local ID 67899dd4-12dd-49c0-a424-9fae916c5522 Raw Audit Messages type=AVC msg=audit(1540219825.728:73583): avc: denied { signull } for pid=1186 comm="winbindd" scontext=system_u:system_r:winbind_t:s0 tcontext=system_u:system_r:systemd_hostnamed_t:s0 tclass=process permissive=0 Hash: winbindd,winbind_t,systemd_hostnamed_t,process,signull Version-Release number of selected component: selinux-policy-3.14.1-44.fc28.noarch Additional info: component: selinux-policy reporter: libreport-2.9.7 hashmarkername: setroubleshoot kernel: 4.20.3-200.fc29.x86_64 type: libreport
