Commit "fib: RCU conversion of fib_lookup()" removed rcu_read_lock() from __mkroute_output but left a couple of calls to rcu_read_unlock() in there. This causes lockdep to complain that the rcu_read_unlock() call in __ip_route_output_key causes a lock inbalance and quickly crashes the kernel. The below fixes this for me. Signed-off-by:

Do not set num_rx_queues in netif_set_real_num_rx_queues() some drivers will increase the real_num_rx_queues later due to a feature changes or available interrupts increasing. By setting num_rx_queues here this ends up creating a cap on the number of rx queues available. For example the ixgbe driver sets the max number of queues it intends to use ever then sets the current number in use with the netif_set_num_{rx|tx}_queues calls. With the current implementation the number of rx queues gets limited so when a feature such as DCB or FCoE is enabled the queues are no longer available. kobjects will only be allocated for real_num_rx_queues so the waste in memory is minimal.

In diva_mnt_add_xdi_adapter() we do this: strcpy (clients[id].drvName, tmp); strcpy (clients[id].Dbg.drvName, tmp); The "clients[id].drvName" is a 128 character buffer and "clients[id].Dbg.drvName" was originally a 16 character buffer but I've changed it to 128 as well. We don't actually use 128 characters but we do use more than 16. I've also changed the size of "tmp" to 128 characters instead of 256. Signed-off-by:

This is the second step for neighbour RCU conversion. (first was commit d6bf7817 : RCU conversion of neigh hash table) neigh_lookup() becomes lockless, but still take a reference on found neighbour. (no more read_lock()/read_unlock() on tbl->lock) struct neighbour gets an additional rcu_head field and is freed after an RCU grace period. Future work would need to eventually not take a reference on neighbour for temporary dst (DST_NOCACHE), but this would need dst->_neighbour to use a noref bit like we did for skb->_dst.

When an interface was enslaved when it was down, bonding thinks it has speed -1 even after it goes up. This leads into selecting a wrong active interface in active/backup mode on mixed 10G/1G or 1G/100M environment. before: bonding: bond0: link status definitely up for interface eth5, 100 Mbps full duplex. bonding: bond0: link status definitely up for interface eth0, 100 Mbps full duplex. after: bonding: bond0: link status definitely up for interface eth5, 10000 Mbps full duplex. bonding: bond0: link status definitely up for interface eth0, 1000 Mbps full duplex.
