Subject: [PATCH 1/1] Fix regression in s_config_in_context() method
Prior to commit 137286e9baecf6a3ba97722ef1b49c851b531810
a config would not be considered in context if:
a) it has no address family flags set
b) it has the address family flag of current context set
Since above commit config is considered in context if the
address family is the opposite of current context.
The result is that a config with two dhcp-host records,
one for IPv6 and another for IPv4 no longer works, for
example with the below config the config with the IPv6
address would be considered in context for a DHCP(v4)
request.
dhcp-host=52:54:00:bc:c3:fd,172.20.0.11,host2
dhcp-host=52:54:00:bc:c3:fd,[fd12:3456:789a:1::aadd],host2
This commit restores the previous behavior.
