Message-Id: <20141119.151948.1499529626052606712.davem@davemloft.net> Date: Wed, 19 Nov 2014 15:19:48 -0500 (EST) From: David Miller <davem@...emloft.net> To: joestringer@...ira.com Cc: netdev@...r.kernel.org, linux-kernel@...r.kernel.org, pshelar@...ira.com, dev@...nvswitch.org Subject: Re: [PATCH net] openvswitch: Fix mask generation for IPv6 labels. From: Joe Stringer <joestringer@...ira.com> Date: Tue, 18 Nov 2014 10:54:17 -0800 > When userspace doesn't provide a mask, OVS datapath generates a fully > unwildcarded mask for the flow. This is done by taking a copy of the > flow key, then iterating across its attributes, setting all values to > 0xff. This works for most attributes, as the length of the netlink > attribute typically matches the length of the value. However, IPv6 > labels only use the lower 20 bits of the field. This patch makes a > special case to handle this. > > This fixes the following error seen when installing IPv6 flows without a mask: > > openvswitch: netlink: Invalid IPv6 flow label value (value=ffffffff, max=fffff) > > Signed-off-by: Joe Stringer <joestringer@...ira.com> Judging by the discussion ongoing about this patch, I am assuming there will be a new version of this change forthcoming.
