From: "Paul E. McKenney" <paulmck at linux.vnet.ibm.com> The sparse checking for rcu_assign_pointer() was recently upgraded to reject non-__kernel address spaces. This also rejects __rcu, which is almost always the right thing to do. However, the use in __br_mdb_del() is legitimate: They are assigning a pointer to an element from an RCU-protected list, and all elements of this list are already visible to caller. This commit therefore silences these false positives by laundering the pointers using ACCESS_ONCE() as suggested by Eric Dumazet and Josh Triplet...

Hi, Here are two, small feature changes I would like to submit to increase the usefulness of the multicast snooping of the bridge code. The first patch is an unaltered one I had submitted before, but since it got no feedback I'm resubmitting it here for net-next. With the recently added patch to disable snooping if there is no querier (b00589af + 248ba8ec05 + 8d50af4fb), it should be a safe

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

Changes since v9: * series re-ordering so make functionality more distinct. Basic vlan filtering is patches 1-4. Support for PVID/untagged vlans is patches 5 and 6. VLAN support for FDB/MDB is patches 7-11. Patch 12 is still additional egress policy. * Slight simplification to code that extracts the VID from skb. Since we now depend on the vlan module, at the time of input skb_tci is
