commit e2d6e2d5d2388cd7c135a50129466aaa7ca85cbf Author: Slawek Kaplonski <[email protected]> Date: Mon Aug 23 13:01:37 2021 +0200 Remove dhcp_extra_opt value after first newline character Passing newline to the dnsmasq may cause security issues, especially that in case of Neutron that dhcp options' values are controlled by cloud users. This patch removes everything what is after first newline character in the dhcp_extra_opt's values before passing them to dnsmasq.
