From c6817e4c32d8c4118405d2dec30ac1c264349085 Mon Sep 17 00:00:00 2001 From: James Morris Date: Mon, 30 Oct 2006 18:56:06 -0800 Subject: [IPV6]: return EINVAL for invalid address with flowlabel lease request Currently, when an application requests a lease for a flowlabel via the IPV6_FLOWLABEL_MGR socket option, no error is returned if an invalid type of destination address is supplied as part of the request, leading to a silent failure. This patch ensures that EINVAL is returned to the application in this case. Signed-off-by: James Morris Signed-off-by: David S.
