What were you trying to do that didn't work?
It seems that the dhcpcd service starts and runs successfully in enforcing mode, but each (re)start of the service triggers several SELinux denials.
Please provide the package NVR for which bug is seen:
dhcpcd-10.0.2-7.el9.x86_64
selinux-policy-38.1.25-1.el9.noarch
selinux-policy-devel-38.1.25-1.el9.noarch
selinux-policy-targeted-38.1.25-1.el9.noarch
How reproducible:
always
Steps to reproduce
- get a RHEL-9.4 machine (targeted policy is active)
- install the dhcpcd package (from EPEL repository)
- start the dhcpcd service
- search for SELinux denials
Expected results
No SELinux denials are triggered.
Actual results
