Jouni Malinen f3f9258678 nl80211: Check that function pointer != NULL before using it
NL80211_CMD_GET_MESH_PARAMS and NL80211_CMD_SET_MESH_PARAMS handlers
did not verify whether a function pointer is NULL (not supported by
the driver) before trying to call the function. The former nl80211
command is available for unprivileged users, too, so this can
potentially allow normal users to kill networking (or worse..) if
mac80211 is built without CONFIG_MAC80211_MESH=y.

Jorge Boncompte [DTI2] 2bad35b7c9 netns: oops in ip[6]_frag_reasm incrementing stats
dev can be NULL in ip[6]_frag_reasm for skb's coming from RAW sockets.

Quagga's OSPFD sends fragmented packets on a RAW socket, when netfilter
conntrack reassembles them on the OUTPUT path you hit this code path.

You can test it with something like "hping2 -0 -d 2000 -f AA.BB.CC.DD"

With help from Jarek Poplawski.

Bjørn Mork 1b1d8f73a4 ipv6: fix display of local and remote sit endpoints
This fixes the regressions cause by
commit 1326c3d5a4
(v2.6.28-rc6-461-g23a12b1) broke the display of local and remote
addresses of an SIT tunnel in iproute2.

nt->parms is used by ipip6_tunnel_init() and therefore need to be
initialized first.

Herbert Xu 303c6a0251 gro: Fix legacy path napi_complete crash
On the legacy netif_rx path, I incorrectly tried to optimise
the napi_complete call by using __napi_complete before we reenable
IRQs.  This simply doesn't work since we need to flush the held
GRO packets first.

This patch fixes it by doing the obvious thing of reenabling
IRQs first and then calling napi_complete.

Jouni Malinen 055249d20d mac80211: Fix panic on fragmentation with power saving
It was possible to hit a kernel panic on NULL pointer dereference in
dev_queue_xmit() when sending power save buffered frames to a STA that
woke up from sleep. This happened when the buffered frame was requeued
for transmission in ap_sta_ps_end(). In order to avoid the panic, copy
the skb->dev and skb->iif values from the first fragment to all other
fragments.

Christoph Paasch d1238d5337 netfilter: conntrack: check for NEXTHDR_NONE before header sanity checking
NEXTHDR_NONE doesn't has an IPv6 option header, so the first check
for the length will always fail and results in a confusing message
"too short" if debugging enabled. With this patch, we check for
NEXTHDR_NONE before length sanity checkings are done.

We currently use the negative value in the conntrack code to encode
the packet verdict in the error. As NF_DROP is equal to 0, inverting
NF_DROP makes no sense and, as a result, no packets are ever dropped.

Trond Myklebust eb9b55ab4d SUNRPC: Tighten up the task locking rules in __rpc_execute()
We should probably not be testing any flags after we've cleared the
RPC_TASK_RUNNING flag, since rpc_make_runnable() is then free to assign the
rpc_task to another workqueue, which may then destroy it.

We can fix any races with rpc_make_runnable() by ensuring that we only
clear the RPC_TASK_RUNNING flag while holding the rpc_wait_queue->lock that
the task is supposed to be sleeping on (and then checking whether or not
the task really is sleeping).

David S. Miller 9d40bbda59 vlan: Fix vlan-in-vlan crashes.
As analyzed by Patrick McHardy, vlan needs to reset it's
netdev_ops pointer in it's ->init() function but this
leaves the compat method pointers stale.

Add a netdev_resync_ops() and call it from the vlan code.

Any other driver which changes ->netdev_ops after register_netdevice()
will need to call this new function after doing so too.

With help from Patrick McHardy.
