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
