From e5b335830efe21f560383f4a2003450b42923e63 Mon Sep 17 00:00:00 2001 From: Christian Poessinger Date: Fri, 26 Feb 2021 19:10:08 +0100 Subject: vyos.ifconfig: T1579: remove calls to vyos.ifconfig.Interface.get_config() Interface.get_config() was always a pure helper which exposed a "per interface type" dictionary which was then fed by the caller to create interfaces by iproute2 which required additional options during creation time. Such interfaces had been: * tunnel * vxlan * geneve * macsec * wifi * macvlan / pseudo-ethernet The code was always duplicated to convert from the VyOS CLI based get_config_dict() to a dict which can be used to feed iproute2. This path has been removed and we now always feed in the entire dictionary retrieved by get_config_dict() or in the interfaces case, it's high-level wrapper get_interface_dict() to the interface we wan't to create. This also adds the - personally long awaited - possibility to get rid of the derived tunnel classes for e.g. GRE, IPIP, IPIP6 and so on. --- src/conf_mode/interfaces-erspan.py | 32 ++++++++++------------- src/conf_mode/interfaces-geneve.py | 12 +-------- src/conf_mode/interfaces-l2tpv3.py | 22 ++-------------- src/conf_mode/interfaces-macsec.py | 10 +------- src/conf_mode/interfaces-openvpn.py | 5 +--- src/conf_mode/interfaces-pseudo-ethernet.py | 12 +-------- src/conf_mode/interfaces-tunnel.py | 40 +---------------------------- src/conf_mode/interfaces-vxlan.py | 13 +--------- src/conf_mode/interfaces-wireless.py | 11 +------- 9 files changed, 22 insertions(+), 135 deletions(-) (limited to 'src') diff --git a/src/conf_mode/interfaces-erspan.py b/src/conf_mode/interfaces-erspan.py index 2d65b834c..97ae3cf55 100755 --- a/src/conf_mode/interfaces-erspan.py +++ b/src/conf_mode/interfaces-erspan.py @@ -48,7 +48,7 @@ def get_config(config=None): conf = Config() base = ['interfaces', 'erspan'] erspan = get_interface_dict(conf, base) - + tmp = leaf_node_changed(conf, ['encapsulation']) if tmp: erspan.update({'encapsulation_changed': {}}) @@ -58,30 +58,30 @@ def get_config(config=None): def verify(erspan): if 'deleted' in erspan: return None - + if 'encapsulation' not in erspan: raise ConfigError('Unable to detect the following ERSPAN tunnel encapsulation'\ '{ifname}!'.format(**erspan)) verify_mtu_ipv6(erspan) verify_tunnel(erspan) - + key = dict_search('parameters.ip.key',erspan) if key == None: raise ConfigError('parameters.ip.key is mandatory for ERSPAN tunnel') - + def generate(erspan): return None def apply(erspan): - if 'deleted' in erspan or 'encapsulation_changed' in erspan: - if erspan['ifname'] in interfaces(): - tmp = Interface(erspan['ifname']) - tmp.remove() - if 'deleted' in erspan: - return None - + if 'deleted' in erspan or 'encapsulation_changed' in erspan: + if erspan['ifname'] in interfaces(): + tmp = Interface(erspan['ifname']) + tmp.remove() + if 'deleted' in erspan: + return None + dispatch = { 'erspan': ERSpanIf, 'ip6erspan': ER6SpanIf @@ -90,14 +90,8 @@ def apply(erspan): # We need to re-map the tunnel encapsulation proto to a valid interface class encap = erspan['encapsulation'] klass = dispatch[encap] - - conf = deepcopy(erspan) - - conf.update(klass.get_config()) - - del conf['ifname'] - - erspan_tunnel = klass(erspan['ifname'],**conf) + + erspan_tunnel = klass(**erspan) erspan_tunnel.change_options() erspan_tunnel.update(erspan) diff --git a/src/conf_mode/interfaces-geneve.py b/src/conf_mode/interfaces-geneve.py index 979a5612e..2a63b60aa 100755 --- a/src/conf_mode/interfaces-geneve.py +++ b/src/conf_mode/interfaces-geneve.py @@ -72,18 +72,8 @@ def apply(geneve): g.remove() if 'deleted' not in geneve: - # This is a special type of interface which needs additional parameters - # when created using iproute2.
