From d13b91462487e090b32c0d1ecf9139a2271b4837 Mon Sep 17 00:00:00 2001 From: Christian Poessinger Date: Wed, 17 Nov 2021 21:42:26 +0100 Subject: snmp: T3996: fix invalid IPv6 localhost handling when using listen-address We need to use a temporary variable when validating the tuple if address is used. If not the else branch will always add the tuple to the list of addresses used for listen-address. --- smoketest/scripts/cli/test_service_snmp.py | 33 ++++++++++++++++++++++-------- 1 file changed, 24 insertions(+), 9 deletions(-) (limited to 'smoketest/scripts/cli') diff --git a/smoketest/scripts/cli/test_service_snmp.py b/smoketest/scripts/cli/test_service_snmp.py index 008271102..e15d186bc 100755 --- a/smoketest/scripts/cli/test_service_snmp.py +++ b/smoketest/scripts/cli/test_service_snmp.py @@ -22,6 +22,7 @@ from base_vyostest_shim import VyOSUnitTestSHIM from vyos.configsession import ConfigSession from vyos.configsession import ConfigSessionError from vyos.template import is_ipv4 +from vyos.template import address_from_cidr from vyos.util import read_file from vyos.util import process_named_running @@ -36,16 +37,29 @@ def get_config_value(key): return tmp[0] class TestSNMPService(VyOSUnitTestSHIM.TestCase): - def setUp(self): + @classmethod + def setUpClass(cls): + super(cls, cls).setUpClass() + # ensure we can also run this test on a live system - so lets clean # out the current configuration :) + cls.cli_delete(cls, base_path) + + def tearDown(self): + # delete testing SNMP config self.cli_delete(base_path) + self.cli_commit() def test_snmp_basic(self): + dummy_if = 'dum7312' + dummy_addr = '100.64.0.1/32' + self.cli_set(['interfaces', 'dummy', dummy_if, 'address', dummy_addr]) + # Check if SNMP can be configured and service runs clients = ['192.0.2.1', '2001:db8::1'] networks = ['192.0.2.128/25', '2001:db8:babe::/48'] - listen = ['127.0.0.1', '::1'] + listen = ['127.0.0.1', '::1', address_from_cidr(dummy_addr)] + port = '5000' for auth in ['ro', 'rw']: community = 'VyOS' + auth @@ -56,7 +70,7 @@ class TestSNMPService(VyOSUnitTestSHIM.TestCase): self.cli_set(base_path + ['community', community, 'network', network]) for addr in listen: - self.cli_set(base_path + ['listen-address', addr]) + self.cli_set(base_path + ['listen-address', addr, 'port', port]) self.cli_set(base_path + ['contact', 'maintainers@vyos.io']) self.cli_set(base_path + ['location', 'qemu']) @@ -68,16 +82,18 @@ class TestSNMPService(VyOSUnitTestSHIM.TestCase): # thus we need to transfor this into a proper list config = get_config_value('agentaddress') expected = 'unix:/run/snmpd.socket' + self.assertIn(expected, config) + for addr in listen: if is_ipv4(addr): - expected += ',udp:{}:161'.format(addr) + expected = f'udp:{addr}:{port}' else: - expected += ',udp6:[{}]:161'.format(addr) - - self.assertTrue(expected in config) + expected = f'udp6:[{addr}]:{port}' + self.assertIn(expected, config) # Check for running process self.assertTrue(process_named_running(PROCESS_NAME)) + self.cli_delete(['interfaces', 'dummy', dummy_if]) def test_snmpv3_sha(self): @@ -86,7 +102,7 @@ class TestSNMPService(VyOSUnitTestSHIM.TestCase): self.cli_set(base_path + ['v3', 'engineid', '000000000000000000000002']) self.cli_set(base_path + ['v3', 'group', 'default', 'mode', 'ro']) - # check validate() - a view must be created before this can be comitted + # check validate() - a view must be created before this can be committed with self.assertRaises(ConfigSessionError): self.cli_commit() @@ -152,4 +168,3 @@ class TestSNMPService(VyOSUnitTestSHIM.TestCase): if __name__ == '__main__': unittest.main(verbosity=2) - -- cgit v1.2.3
