+Subject: dhcp: Nameserver issue on IP address renewal after lease expiry
+
+After lease expiry and releasing its current IP, when device eventually
+gets an IP address, DNS resolution stops working. This is because
+nameserver list in service structure is empty. On lease expiry when
+apply_dhcp_invalidate_on_network(dhcp) is called, it removes
+nameservers from the service structure but it does not free namservers in
+dhcp structure. Now next time when device gets an IP address and
+apply_lease_available_on_network is called, nameserver is not updated as
+compare_string_arrays(nameservers, dhcp->nameservers) would return true.
+The fix for this would be to free dhcp->nameservers when lease is lost so
+that on successful renewal next time, nameserver properly gets updated.

+Subject: dhcp: Timeserver issue on IP address renewal after lease expiry
+
+Similar to nameservers, timeservers are also checked against previous
+values when added. When there is no change in timeservers when the DHCP
+lease is lost and reacquired, the service will not be notified if the
+timeservers have changed. With timeservers removed on lease lost,
+timeservers are not properly updated once reacquired.
+
+Fix this by removing timeservers from the dhcp struct when lease is lost.
