Description of problem: When creating a new namespace, and add an interface to it, then dhcp in the new namespaces dhclient cli, the cli will fail. Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. Create an interface, e.g. a macvtap device, and a new namespaces including a new net namespaces. 2. Add the interface to the new namespaces 3. Up and dhcp the interface in the new namespaces Actual results: dhcp failed and the interface has not any IP addr. Expected results: The interface gets an IP addr, broadcast addr, ..., etc. Additional info: SELinux is preventing dhclient from net_bind_service access on the cap_userns Unknown. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that dhclient should be allowed net_bind_service access on the Unknown cap_userns 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 'dhclient' --raw | audit2allow -M my-dhclient # semodule -X 300 -i my-dhclient.pp Additional Information: Source Context unconfined_u:system_r:dhcpc_t:s0-s0:c0.c1023 Target Context unconfined_u:system_r:dhcpc_t:s0-s0:c0.c1023 Target Objects Unknown [ cap_userns ] Source dhclient Source Path dhclient Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.13.1-191.14.fc24.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux localhost 4.7.2-201.fc24.x86_64 #1 SMP Fri Aug 26 15:58:40 UTC 2016 x86_64 x86_64 Alert Count 1 First Seen 2016-09-12 16:11:22 CST Last Seen 2016-09-12 16:11:22 CST Local ID ee534592-100b-47a8-9513-18bf8fd5ec69 Raw Audit Messages type=AVC msg=audit(1473667882.131:215): avc: denied { net_bind_service } for pid=2366 comm="dhclient" capability=10 scontext=unconfined_u:system_r:dhcpc_t:s0-s0:c0.c1023 tcontext=unconfined_u:system_r:dhcpc_t:s0-s0:c0.c1023 tclass=cap_userns permissive=0 Hash: dhclient,dhcpc_t,dhcpc_t,cap_userns,net_bind_service
