c7c694d196 [AX.25]: Fix potencial memory hole.
If the AX.25 dialect chosen by the sysadmin is set to DAMA master / 3
(or DAMA slave / 2, if CONFIG_AX25_DAMA_SLAVE=n) ax25_kick() will fall
through the switch statement without calling ax25_send_iframe() or any
other function that would eventually free skbn thus leaking the packet.

Fix by restricting the sysctl inferface to allow only actually supported
AX.25 dialects.

The system administration mistake needed for this to happen is rather
unlikely, so this is an uncritical hole.

Coverity #651.

72df16f109 [PATCH] ieee80211: Fix QoS is not active problem
Fix QoS is not active even the network and the card is QOS enabled.
The problem is we pass the wrong ieee80211_network address to
ipw_handle_beacon/ipw_handle_probe_response, thus the
ieee80211_network->qos_data.active will not be set, causing the driver
not sending QoS frames at all.

529bf6be5c [PATCH] fix file counting
I have benchmarked this on an x86_64 NUMA system and see no significant
performance difference on kernbench.  Tested on both x86_64 and powerpc.

The way we do file struct accounting is not very suitable for batched
freeing.  For scalability reasons, file accounting was
constructor/destructor based.  This meant that nr_files was decremented
only when the object was removed from the slab cache.  This is susceptible
to slab fragmentation.  With RCU based file structure, consequent batched
freeing and a test program like Serge's, we just speed this up and end up
with a very fragmented slab -

llm22:~ # cat /proc/sys/fs/file-nr
587730  0       758844

At the same time, I see only a 2000+ objects in filp cache.  The following
patch I fixes this problem.

This patch changes the file counting by removing the filp_count_lock.
Instead we use a separate percpu counter, nr_files, for now and all
accesses to it are through get_nr_files() api.  In the sysctl handler for
nr_files, we populate files_stat.nr_files before returning to user.

Counting files as an when they are created and destroyed (as opposed to
inside slab) allows us to correctly count open files with RCU.

752c1f4c78 [IPSEC]: Kill post_input hook and do NAT-T in esp_input directly
The only reason post_input exists at all is that it gives us the
potential to adjust the checksums incrementally in future which
we ought to do.

However, after thinking about it for a bit we can adjust the
checksums without using this post_input stuff at all.  The crucial
point is that only the inner-most NAT-T SA needs to be considered
when adjusting checksums.  What's more, the checksum adjustment
comes down to a single u32 due to the linearity of IP checksums.

We just happen to have a spare u32 lying around in our skb structure :)
When ip_summed is set to CHECKSUM_NONE on input, the value of skb->csum
is currently unused.  All we have to do is to make that the checksum
adjustment and voila, there goes all the post_input and decap structures!

I've left in the decap data structures for now since it's intricately
woven into the sec_path stuff.  We can kill them later too.

f8d0e3f115 [NET] ethernet: Fix first packet goes out with MAC 00:00:00:00:00:00
When you turn off ARP on a netdevice then the first packet always goes
out with a dstMAC of all zeroes. This is because the first packet is
used to resolve ARP entries. Even though the ARP entry may be resolved
(I tried by setting a static ARP entry for a host i was pinging from),
it gets overwritten by virtue of having the netdevice disabling ARP.

Subsequent packets go out fine with correct dstMAC address (which may
be why people have ignored reporting this issue).

To cut the story short: 

the culprit code is in net/ethernet/eth.c::eth_header()

----
        /*
         *      Anyway, the loopback-device should never use this
function...
         */

        if (dev->flags & (IFF_LOOPBACK|IFF_NOARP))
        {
                memset(eth->h_dest, 0, dev->addr_len);
                return ETH_HLEN;
        }

	if(daddr)
        {
                memcpy(eth->h_dest,daddr,dev->addr_len);
                return ETH_HLEN;
        }

----

Note how the h_dest is being reset when device has IFF_NOARP.

As a note:
All devices including loopback pass a daddr. loopback in fact passes
a 0 all the time ;-> 
This means i can delete the check totaly or i can remove the IFF_NOARP

Alexey says:
--------------------
I think, it was me who did this crap. It was so long ago I do not remember
why it was made.

I remember some troubles with dummy device. It tried to resolve
addresses, apparently, without success and generated errors instead of
blackholing. I think the problem was eventually solved at neighbour
level.

After some thinking I suspect the deletion of this chunk could change
behaviour of some parts which do not use neighbour cache f.e. packet
socket.

I think safer approach would be to move this chunk after if (daddr).
And the possibility to remove this completely could be analyzed later.

Patch updated with Alexey's safer suggestions.

7c6de05884 [NETFILTER]: nf_conntrack: Fix TCP/UDP HW checksum handling for IPv6 packet
If skb->ip_summed is CHECKSUM_HW here, skb->csum includes checksum
of actual IPv6 header and extension headers. Then such excess
checksum must be subtruct when nf_conntrack calculates TCP/UDP checksum
with pseudo IPv6 header. Spotted by Ben Skeggs.

763ecff187 [NETFILTER]: nf_conntrack: attach conntrack to locally generated ICMPv6 error
Locally generated ICMPv6 errors should be associated with the conntrack
of the original packet. Since the conntrack entry may not be in the hash
tables (for the first packet), it must be manually attached.

08857fa745 [NETFILTER]: nf_conntrack: attach conntrack to TCP RST generated by ip6t_REJECT
TCP RSTs generated by the REJECT target should be associated with the
conntrack of the original TCP packet. Since the conntrack entry is
usually not is the hash tables, it must be manually attached.
