           Summary: os_common_find_running_interfaces() fails on NetBSD-5
           Product: Exim
           Version: 4.69
          Platform: x86
        OS/Version: NetBSD
            Status: NEW
          Severity: bug
          Priority: high
         Component: Networking
        AssignedTo: nigel@...
        ReportedBy: abs@...
                CC: exim-dev@...


os_common_find_running_interfaces() can fail on NetBSD-5 in some cases as the
test for the data being >sizeof(addrbuf) (256) is triggered.

Increasing addrbuf to [512] works around this, but a better solution would be
to use the much cleaner getifaddrs() instead of the multiple ioctls()

Will attach a patch which increases addrbuf to [512], and adds an #ifdef
HAVE_GETIFADDRS (initially only enabled for NetBSD)
