From 30c177a93731a1451bbd30f7d8e2cde15b85f081 Mon Sep 17 00:00:00 2001 From: Yu Watanabe Date: Mon, 17 Aug 2026 08:06:23 +0900 Subject: [PATCH] test-network: add test cases for IPv6ProxyNDP=no In that case, IPv6 proxy neighbor entries are ignored. This also checks IPv6ProxyNDP=yes is implied if an IPv6 proxy neighbor address is specified. --- test/test-network/systemd-networkd-tests.py | 23 ++++++++++++++++++++- 1 file changed, 22 insertions(+), 1 deletion(-) diff --git a/test/test-network/systemd-networkd-tests.py b/test/test-network/systemd-networkd-tests.py index 961a3f49a7..7ca0567bab 100755 --- a/test/test-network/systemd-networkd-tests.py +++ b/test/test-network/systemd-networkd-tests.py @@ -5370,9 +5370,30 @@ class NetworkdNetworkTests(unittest.TestCase, Utilities): output = check_output('ip neighbor show proxy dev dummy98') print(output) - for i in range(1, 5): + for i in range(1, 6): self.assertRegex(output, f'2607:5300:203:5215:{i}::1 *proxy') + # When a proxy NDP address is specified, IPv6ProxyNDP=yes is implied. + self.check_ipv6_sysctl_attr('dummy98', 'proxy_ndp', '1') + + with open( + os.path.join(network_unit_dir, '25-ipv6-proxy-ndp.network'), mode='a', encoding='utf-8' + ) as f: + f.write('[Network]\nIPv6ProxyNDP=no\n') + + stop_networkd() + remove_link('dummy98') + start_networkd() + self.wait_online('dummy98:routable') + + # If IPv6ProxyNDP= is disabled, proxy NDP addresses are ignored. + output = check_output('ip neighbor show proxy dev dummy98') + print(output) + for i in range(1, 6): + self.assertNotRegex(output, f'2607:5300:203:5215:{i}::1 *proxy') + + self.check_ipv6_sysctl_attr('dummy98', 'proxy_ndp', '0') + def test_ipv4_proxy_arp(self): copy_network_unit('25-ipv4-proxy-arp.network', '12-dummy.netdev') start_networkd()
