Description of problem: SELinux is preventing /usr/lib/systemd/systemd-resolved from 'name_bind' accesses on the udp_socket port 5353. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that systemd-resolved should be allowed name_bind access on the port 5353 udp_socket 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 'systemd-resolve' --raw | audit2allow -M my-systemdresolve # semodule -X 300 -i my-systemdresolve.pp Additional Information: Source Context system_u:system_r:systemd_resolved_t:s0 Target Context system_u:object_r:howl_port_t:s0 Target Objects port 5353 [ udp_socket ] Source systemd-resolve Source Path /usr/lib/systemd/systemd-resolved Port 5353 Host (removed) Source RPM Packages systemd-239-3.fc29.x86_64 Target RPM Packages Policy RPM selinux-policy-3.14.2-32.fc29.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 4.18.5-300.fc29.x86_64 #1 SMP Fri Aug 24 17:16:35 UTC 2018 x86_64 x86_64 Alert Count 75 First Seen 2018-09-07 18:01:03 CEST Last Seen 2018-09-09 00:26:09 CEST Local ID 322b2f9c-f349-43a9-b04a-dd39bb810705 Raw Audit Messages type=AVC msg=audit(1536445569.401:28497): avc: denied { name_bind } for pid=963 comm="systemd-resolve" src=5353 scontext=system_u:system_r:systemd_resolved_t:s0 tcontext=system_u:object_r:howl_port_t:s0 tclass=udp_socket permissive=0 type=SYSCALL msg=audit(1536445569.401:28497): arch=x86_64 syscall=bind success=no exit=EACCES a0=f a1=7fff8ad70880 a2=1c a3=557aff680428 items=0 ppid=1 pid=963 auid=4294967295 uid=193 gid=193 euid=193 suid=193 fsuid=193 egid=193 sgid=193 fsgid=193 tty=(none) ses=4294967295 comm=systemd-resolve exe=/usr/lib/systemd/systemd-resolved subj=system_u:system_r:systemd_resolved_t:s0 key=(null) Hash: systemd-resolve,systemd_resolved_t,howl_port_t,udp_socket,name_bind Version-Release number of selected component: selinux-policy-3.14.2-32.fc29.noarch Additional info: component: selinux-policy reporter: libreport-2.9.5 hashmarkername: setroubleshoot kernel: 4.18.5-300.fc29.x86_64 type: libreport Potential duplicate: bug 1430520
