Package: ifupdown Version: 0.7.2 Severity: important Hi,
RFC 3021 states that when a /31 netmask is specified, then the directed broadcast address cannot be used and the limited broadcast address (255.255.255.255) MUST be used for all broadcast communication. The current version of ifupdown however calculates the broadcast and network addresses for a /31 subnet on an `inet' interface in the `regular' way (address | ~netmask, as can be seen in compute_v4_broadcast()) and configures the interface in a way that renders it inoperable. Manually specifying a broadcast address in /etc/network/interfaces, works around this issue. As /31 subnets are commonly used in router interconnection links, this behaviour potentially affects the network connectivity of more systems.
