# brintOS wasm32-hwjs: the configuration igmpproxy reads at startup, and
# the subject of `igmpproxy -d -v -v /etc/igmpproxy.conf'.
#
# UPSTREAM SHIPS A FILE WITH NO `whitelist' IN IT, WHICH IS WHY THIS PORT
# BUNDLES ANOTHER. igmpproxy's own igmpproxy.conf is installed by
# dist_sysconf_DATA and is a worked example over eth0/eth1/eth2 carrying
# quickleave, two altnets and nothing else. It parses -- unlike radvd's,
# it is not a file the daemon rejects -- but the criterion this port was
# taken on names the WHITELIST among the things a verbose run must log as
# configured, and on a stock image that half has no subject at all.
#
# EVERY VALUE HERE IS DELIBERATELY NON-DEFAULT, against the defaults
# config.c assigns. A suite that asserts a configured value against the
# value igmpproxy would have chosen anyway proves nothing, so each number
# below differs from the default named beside it.
#
# THE INTERFACE NAMES ARE HONEST ABOUT THE MACHINE, AND `lo' IS THE ONLY
# ONE THAT EXISTS. configureVifs() matches a phyint block to an interface
# only when the interface has an address and is NOT IFF_LOOPBACK
# (config.c), so NONE of the three blocks below becomes a VIF on this
# image -- `lo' is excluded by the loopback test and eth0/eth1 are not
# there. That is the platform and not this file; 88-igmpproxy.test scores
# the two apart. Naming `lo' rather than inventing a third ethN keeps the
# file truthful about the one interface the image has, and an upstream
# block is required for the configuration to be a proxy configuration at
# all.

# Send a leave upstream the moment the last downstream member goes away.
