From 2b00a4e03dc375465de7f60f3a6937cbe8ffdf31 Mon Sep 17 00:00:00 2001 From: Tom Yan Date: Sat, 28 May 2016 13:35:01 +0800 Subject: [PATCH] networkd: disable IPv6 for bridge slave If an interface is managed as a bridge slave, we don't want any IP configuration for it. Therefore, disable IPv6 in such case. --- src/network/networkd-link.c | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff --git a/src/network/networkd-link.c b/src/network/networkd-link.c index 377e6f52f45..0d9d228796a 100644 --- a/src/network/networkd-link.c +++ b/src/network/networkd-link.c @@ -110,6 +110,9 @@ static bool link_ipv6_enabled(Link *link) { if (!socket_ipv6_is_supported()) return false; + if (link->network->bridge) + return false; + /* DHCPv6 client will not be started if no IPv6 link-local address is configured. */ return link_ipv6ll_enabled(link) || network_has_static_ipv6_addresses(link->network); } @@ -1586,7 +1589,7 @@ static int link_up(Link *link) { } /* If IPv6 not configured (no static IPv6 address and IPv6LL autoconfiguration is disabled) - for this interface then disable IPv6 else enable it. */ + for this interface, or if it is a bridge slave, then disable IPv6 else enable it. */ (void) link_enable_ipv6(link); if (link->network->mtu) { -- 2.39.2
