From dd0ebffa33728e452ac6e11737c2283f0e390359 Mon Sep 17 00:00:00 2001 From: Christian Breunig Date: Tue, 23 Jul 2024 19:05:21 +0200 Subject: vrf: T6602: verify supplied VRF name on all interface types Only some (e.g. ethernet or wireguard) interfaces validate if the supplied VRF actually exists. If this is not validated, one can pass an invalid VRF to the system which generates an OSError exception. To reproduce set interfaces vxlan vxlan1 vni 1000 set interfaces vxlan vxlan1 remote 1.2.3.4 set interfaces vxlan vxlan1 vrf smoketest results in OSError: [Errno 255] failed to run command: ip link set dev vxlan1 master smoketest_mgmt This commit adds the missing verify_vrf() call to the missing interface types and an appropriate smoketest for all interfaces supporting VRF assignment. --- smoketest/scripts/cli/base_interfaces_test.py | 18 ++++++++++++++++++ 1 file changed, 18 insertions(+) (limited to 'smoketest') diff --git a/smoketest/scripts/cli/base_interfaces_test.py b/smoketest/scripts/cli/base_interfaces_test.py index 4072fd5c2..66b789e94 100644 --- a/smoketest/scripts/cli/base_interfaces_test.py +++ b/smoketest/scripts/cli/base_interfaces_test.py @@ -303,6 +303,24 @@ class BasicInterfaceTest: self.cli_delete(['vrf', 'name', vrf1_name]) self.cli_delete(['vrf', 'name', vrf2_name]) + def test_add_to_invalid_vrf(self): + if not self._test_vrf: + self.skipTest('not supported') + + # move interface into first VRF + for interface in self._interfaces: + for option in self._options.get(interface, []): + self.cli_set(self._base_path + [interface] + option.split()) + self.cli_set(self._base_path + [interface, 'vrf', 'invalid']) + + # check validate() - can not use a non-existing VRF + with self.assertRaises(ConfigSessionError): + self.cli_commit() + + for interface in self._interfaces: + self.cli_delete(self._base_path + [interface, 'vrf', 'invalid']) + self.cli_set(self._base_path + [interface, 'description', 'test_add_to_invalid_vrf']) + def test_span_mirror(self): if not self._mirror_interfaces: self.skipTest('not supported') -- cgit v1.2.3
