Description of problem: SELinux is preventing dhclient-script from 'getattr' accesses on the file /usr/libexec/chrony-helper. ***** Plugin catchall (100. confidence) suggests ************************** If si crede che dhclient-script dovrebbe avere possibilità di accesso getattr sui chrony-helper file in modo predefinito. Then si dovrebbe riportare il problema come bug. E' possibile generare un modulo di politica locale per consentire questo accesso.

Hi, Could you reproduce it in permissive mode? (#setenforce 0)
Nope, dhclient didn't output any error. Instead had this on AVC SELinux is preventing chrony-helper from ioctl access on the file /usr/libexec/chrony-helper. ***** Plugin catchall (100. confidence) suggests ************************** If cree que de manera predeterminada, chrony-helper debería permitir acceso ioctl sobre chrony-helper file.
