DHCP: Ensure dhcp is running on the interface received from
BSD: Link handling has been simplified, however it is expected
that if an interface supports SIOCGIFMEDIA then it reports
the correct link status via route(4) for reliable operations
BPF: ARP filter is more robust
BSD and sun: Validate RTM message lengths
DHCPv6 (security): Fix a potential read overflow with D6_OPTION_PD_EXCLUDE
was a request to upstream for this so that slaacd could handle the address
and dhcpcd handle rdnss (though TBH I'd just use dhcpcd for everything in
that case).
other fixes);
dhcpcd-7.0.0, 7.0.1 and 7.0.2 are vulnerable to the DHCP6 issue where the
message is copied from the DHCP6 option into a buffer, but is NULL terminated
beyond the size of the buffer.
dhcpcd-6 is not vulnerable.
dhcpcd is a DHCPv4/IPv4LL/IPv6RS/DHCPv6 quad stack client.
It will listen for new interfaces and carrier signals from the kernel
so it can quickly configure each interface as it appears.
dhcpcd has a powerful DHCP expression engine which makes it easy
to decode future RFC DHCP options, or handroll your own.
