[Debian-ha-maintainers] Bug#927311: resource-agents: ethmonitor does not list interfaces without assigned IP address

[Heitor Alves de Siqueira]

Package: resource-agents
Severity: normal

Dear Maintainer,

The is_interface() function in heartbeat/ethmonitor tries to match an
interface to a list obtained from the 'ip' tool. It lists interfaces
using the 'inet' family, which omits interfaces that don't have an IP
address assigned.

If the interface that we're looking for is e.g. a VLAN bridge that does
not have an IP address, it won't show up in the listing and
is_interface() will return false. ethmonitor will miss that interface,
and it won't be available for monitoring.
