From e7dbda3d64e98276570cba3b0c0f94461f77d645 Mon Sep 17 00:00:00 2001 From: Hans Dedecker Date: Thu, 11 Aug 2016 15:53:25 +0200 Subject: proto-shell: Support teardown on layer 3 link loss Commit c6858766 added interface teardown support on layer 3 device link loss mainly for shell protocols who have no proto task like xl2tp. However for shell protocols having a proto task it is not always the correct action to teardown the interface; as an example the PPP daemon can be put into persist state trying to re-establish the link via a hold-off mechanism if layer 3 link loss is detected. Therefore shell handlers can enable via TEARDOWN_ON_L3_LINK_DOWN a proto flag which will teardown the interface when layer 3 link loss is detected Signed-off-by: Hans Dedecker --- interface.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'interface.c') diff --git a/interface.c b/interface.c index b9833d3..0b9893c 100644 --- a/interface.c +++ b/interface.c @@ -414,7 +414,8 @@ interface_l3_dev_cb(struct device_user *dep, enum device_event ev) switch (ev) { case DEV_EVENT_LINK_DOWN: - interface_proto_event(iface->proto, PROTO_CMD_TEARDOWN, false); + if (iface->proto_handler->flags & PROTO_FLAG_TEARDOWN_ON_L3_LINK_DOWN) + interface_proto_event(iface->proto, PROTO_CMD_TEARDOWN, false); break; default: break; -- cgit v1.2.1
