# Keystone Port Reservation
# -------------------------
# Reserve and prevent $KEYSTONE_AUTH_PORT and $KEYSTONE_AUTH_PORT_INT from
# being used as ephemeral ports by the system. The default(s) are 35357 and
# 35358 which are in the Linux defined ephemeral port range (in disagreement
# with the IANA ephemeral port range). This is a workaround for bug #1253482
# where Keystone will try and bind to the port and the port will already be
# in use as an ephemeral port by another process. This places an explicit
# exception into the Kernel for the Keystone AUTH ports.
keystone_ports=${KEYSTONE_AUTH_PORT:-35357},${KEYSTONE_AUTH_PORT_INT:-35358}
# Get any currently reserved ports, strip off leading whitespace
reserved_ports=$(sysctl net.ipv4.ip_local_reserved_ports | awk -F'=' '{print $2;}' | sed 's/^ //')
if [[ -z "${reserved_ports}" ]]; then
# If there are no currently reserved ports, reserve the keystone ports
sudo sysctl -w net.ipv4.ip_local_reserved_ports=${keystone_ports}
else
# If there are currently reserved ports, keep those and also reserve the
# keystone specific ports. Duplicate reservations are merged into a single
# reservation (or range) automatically by the kernel.
sudo sysctl -w net.ipv4.ip_local_reserved_ports=${keystone_ports},${reserved_ports}
