From 1a85e758b105d493bb9d95916816bd206345bc5d Mon Sep 17 00:00:00 2001 From: Christian Poessinger Date: Tue, 21 Jul 2020 15:59:06 +0200 Subject: vyos.util: add common helper to load kernel modules l2tpv3, wireguard, wirelessmodem, nat all require additional Kernel modules to be present on the system. Each and every interface implemented their own way of loading a module - by copying code. Use a generic function, vyos.util.check_kmod() to load any arbitrary kernel module passed as string or list. --- python/vyos/util.py | 9 +++++++++ 1 file changed, 9 insertions(+) (limited to 'python') diff --git a/python/vyos/util.py b/python/vyos/util.py index 924df6b3a..7234be6cb 100644 --- a/python/vyos/util.py +++ b/python/vyos/util.py @@ -652,3 +652,12 @@ def get_bridge_member_config(conf, br, intf): conf.set_level(old_level) return memberconf + +def check_kmod(k_mod): + """ Common utility function to load required kernel modules on demand """ + if isinstance(k_mod, str): + k_mod = k_mod.split() + for module in k_mod: + if not os.path.exists(f'/sys/module/{module}'): + if call(f'modprobe {module}') != 0: + raise ConfigError(f'Loading Kernel module {module} failed') -- cgit v1.2.3 From ebefa38b9fa946fde82a4c9b55122c037598143b Mon Sep 17 00:00:00 2001 From: Christian Poessinger Date: Wed, 1 Jul 2020 19:06:52 +0200 Subject: ethernet: ifconfig: T2653: move to get_config_dict() The current VyOS CLI parser code written in Python contains a ton of duplicates which I can also hold myself accountable for - or maybe mainly me - depends on the angle of judge. While providing a new update() method in vyos.ifconfig.interfaces() this is extended for ethernet based interfaces which also supports 802.1q, 802.1ad VLANs. This commit migrates the existing codebase for an ethernet based interfaces and implements the missing parts for VLANs. Adding or migrating other interfaces (e.g. bridge or bond) will become much easier as they must reuse the entire functionality - we now walk towards a single codepath. Thanks for all who made this combined effort possible!
