Alexey reported that we have GFP_KERNEL allocation when holding the spinlock tcf_lock. Actually we don't have to take that spinlock for all the cases, especially for the new one we just create. To modify the existing actions, we still need this spinlock to make sure the whole update is atomic. For net-next, we can get rid of this spinlock because we already hold the RTNL lock on slow path, and on fast path we can use RCU to protect the metalist. Joint work with Jamal.

When extracting an individual message from a received "bundle" buffer, we just create a clone of the base buffer, and adjust it to point into the right position of the linearized data area of the latter. This works well for regular message reception, but during periods of extremely high load it may happen that an extracted buffer, e.g, a connection probe, is reversed and forwarded through an external interface while the preceding extracted message is still unhandled. When this happens, the header or data area of the preceding message will be partially overwritten by a MAC header, leading to unpredicatable consequences, such as a link reset. We now fix this by ensuring that the msg_reverse() function never returns a cloned buffer, and that the returned buffer always contains sufficient valid head and tail room to be forwarded.

Internal loopback in driver is based on two things - first is the willingness of transmitter to use it [in case of VFs, this can be forced based on VEPA/VEB] and secondly on another vport classification configuration which should match the packet's destination. Current code allows non-linux VFs to configure a 'promisc' mode on Tx, meaning all traffic sent by VF would be loopbacked internally by firmware; This isn't considered a valid mode and as such should be prevented by PF.

We sometimes observe a 'deadly embrace' type deadlock occurring between mutually connected sockets on the same node. This happens when the one-hour peer supervision timers happen to expire simultaneously in both sockets. The scenario is as follows: CPU 1: CPU 2: -------- -------- tipc_sk_timeout(sk1) tipc_sk_timeout(sk2) lock(sk1.slock) lock(sk2.slock) msg_create(probe) msg_create(probe) unlock(sk1.slock) unlock(sk2.slock) tipc_node_xmit_skb() tipc_node_xmit_skb() tipc_node_xmit() tipc_node_xmit() tipc_sk_rcv(sk2) tipc_sk_rcv(sk1) lock(sk2.slock) lock((sk1.slock) filter_rcv() filter_rcv() tipc_sk_proto_rcv() tipc_sk_proto_rcv() msg_create(probe_rsp) msg_create(probe_rsp) tipc_sk_respond() tipc_sk_respond() tipc_node_xmit_skb() tipc_node_xmit_skb() tipc_node_xmit() tipc_node_xmit() tipc_sk_rcv(sk1) tipc_sk_rcv(sk2) lock((sk1.slock) lock((sk2.slock) ===> DEADLOCK ===> DEADLOCK Further analysis reveals that there are three different locations in the socket code where tipc_sk_respond() is called within the context of the socket lock, with ensuing risk of similar deadlocks. We now solve this by passing a buffer queue along with all upcalls where sk_lock.slock may potentially be held. Response or rejected message buffers are accumulated into this queue instead of being sent out directly, and only sent once we know we are safely outside the slock context.

Since 32b8a8e5 ("sit: add IPv4 over IPv4 support") ipip6_err() may be called for packets whose IP protocol is IPPROTO_IPIP as well as those whose IP protocol is IPPROTO_IPV6. In the case of IPPROTO_IPIP packets the correct protocol value is not passed to ipv4_update_pmtu() or ipv4_redirect(). This patch resolves this problem by using the IP protocol of the packet rather than a hard-coded value. This appears to be consistent with the usage of the protocol of a packet by icmp_socket_deliver() the caller of ipip6_err(). I was able to exercise the redirect case by using a setup where an ICMP redirect was received for the destination of the encapsulated packet. However, it appears that although incorrect the protocol field is not used in this case and thus no problem manifests. On inspection it does not appear that a problem will manifest in the fragmentation needed/update pmtu case either. In short I believe this is a cosmetic fix. None the less, the use of IPPROTO_IPV6 seems wrong and confusing.
