'count' is unsigned. It is initialized to zero, then it can be increased
multiple times, and finally it is used in such a way:
>>>> count--;
|
| /* clear timestamp and dma mappings for remaining portion of packet */
| while (count >= 0) {
| count--;
| ...
^
If count is zero here (so, it was never increased), we would have a very
long loop :)

Fix problem in reading the tx_queue recorded in a socket. In
dev_pick_tx, the TX queue is read by doing a check with
sk_tx_queue_recorded on the socket, followed by a sk_tx_queue_get.
The problem is that there is not mutual exclusion across these
calls in the socket so it it is possible that the queue in the
sock can be invalidated after sk_tx_queue_recorded is called so
that sk_tx_queue get returns -1, which sets 65535 in queue_index
and thus dev_pick_tx returns 65536 which is a bogus queue and
can cause crash in dev_queue_xmit.
We fix this by only calling sk_tx_queue_get which does the proper
checks. The interface is that sk_tx_queue_get returns the TX queue
if the sock argument is non-NULL and TX queue is recorded, else it
returns -1. sk_tx_queue_recorded is no longer used so it can be
completely removed.

When configuring DMVPN (GRE + openNHRP) and a GRE remote
address is configured a kernel Oops is observed. The
obserseved Oops is caused by a NULL header_ops pointer
(neigh->dev->header_ops) in neigh_update_hhs() when
void (*update)(struct hh_cache*, const struct net_device*, const unsigned char *)
= neigh->dev->header_ops->cache_update;
is executed. The dev associated with the NULL header_ops is
the GRE interface. This patch guards against the
possibility that header_ops is NULL.
This Oops was first observed in kernel version 2.6.26.8.

The reset_policy() does:
memset(d->tcfd_defdata, 0, SIMP_MAX_DATA);
strlcpy(d->tcfd_defdata, defdata, SIMP_MAX_DATA);
In the original code, the size of d->tcfd_defdata wasn't fixed and if
strlen(defdata) was less than 31, reset_policy() would cause memory
corruption.
Please Note: The original alloc_defdata() assumes defdata is 32
characters and a NUL terminator while reset_policy() assumes defdata is
31 characters and a NUL. This patch updates alloc_defdata() to match
reset_policy() (ie a shorter string). I'm not very familiar with this
code so please review carefully.

commit fc6055a5ba31e2 (net: Introduce skb_orphan_try()) added early
orphaning of skbs.
This unfortunately added a performance regression in skb_tx_hash() in
case of stacked devices (bonding, vlans, ...)
Since skb->sk is now NULL, we cannot access sk->sk_hash anymore to
spread tx packets to multiple NIC queues on multiqueue devices.
skb_tx_hash() in this case only uses skb->protocol, same value for all
flows.
skb_orphan_try() can copy sk->sk_hash into skb->rxhash and skb_tx_hash()
can use this saved sk_hash value to compute its internal hash value.
