I''m trying to configure dsmark qdisc on 2.6.11.4 user mode linux and tc from iproute2-2.6.11-050314. I think I have some mismatch in my setup since adding dsmark qdisc fails *unless* I specify "set_tc_index" argument which I believe should be optional: # tc qdisc add dev eth1 handle 1:0 root dsmark indices 8 RTNETLINK answers: Invalid argument Mar 20 13:00:50 user user.debug

V3: drop debugging printk's update selinux perm table as well V2: drop patch 1/2, export ifindex directly Redesign netlink attributes Improve netlink seq check Handle IPv6 addr as well This patch exports bridge multicast database via netlink message type RTM_GETMDB. Similar to fdb, but currently bridge-specific. We may need to support modify multicast database too

From: Cong Wang <amwang at redhat.com> V4: remove some useless #include some coding style fix V3: drop debugging printk's update selinux perm table as well V2: drop patch 1/2, export ifindex directly Redesign netlink attributes Improve netlink seq check Handle IPv6 addr as well This patch exports bridge multicast database via netlink message type RTM_GETMDB.

Based on net-next. This patch exports port->port_no port->port_id in the end of IFA_INFO_DATA.
