Description of problem: After update of RHEL-8.1.0 compose from RHEL-8.1.0-20190604.7 to RHEL-8.1.0-20190619.2 I hit following selinux denial: time->Sun Jul 7 11:06:22 2019 type=PROCTITLE msg=audit(1562511982.369:33): proctitle=2F7362696E2F6468636C69656E74002D64002D71002D7366002F7573722F6C6962657865632F6E6D2D646863702D68656C706572002D7066002F72756E2F4E6574776F726B4D616E616765722F6468636C69656E742D657468302E706964002D6C66002F7661722F6C69622F4E6574776F726B4D616E616765722F6468636C69 type=SYSCALL msg=audit(1562511982.369:33): arch=c000003e syscall=257 success=no exit=-13 a0=ffffff9c a1=7ffea51c0e9a a2=80241 a3=1a4 items=0 ppid=811 pid=884 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=4294967295 comm="dhclient" exe="/usr/sbin/dhclient" subj=system_u:system_r:dhcpc_t:s0 key=(null) type=AVC msg=audit(1562511982.369:33): avc: denied { write } for pid=884 comm="dhclient" name="NetworkManager" dev="tmpfs" ino=22589 scontext=system_u:system_r:dhcpc_t:s0 tcontext=system_u:object_r:NetworkManager_var_run_t:s0 tclass=dir permissive=0 I have this modification of NetworkManager configuration: echo -e "[main]\ndhcp=dhclient" > /etc/NetworkManager/conf.d/lnst.conf There were two changes between the two composes that may have caused this issue: selinux-policy-3.14.3-7.el8 -> selinux-policy-3.14.3-9.el8 NetworkManager-1:1.14.0-14.el8 -> NetworkManager-1:1.20.0-0.1.el8 Version-Release number of selected component (if applicable): NetworkManager-1:1.20.0-0.1.el8 selinux-policy-3.14.3-9.el8 How reproducible: 100% Steps to Reproduce: 1. clone this beaker job https://beaker.engineering.redhat.com/jobs/3654957 or simply setup NetworkManager to use dhclient for DHCP instead of internal one that seems to work without any issues 2. 3. Actual results: selinux denial Expected results: no selinux denial Additional info:
