====================
The following patchset contains Netfilter/IPVS fixes for 3.10-rc3,
they are:
* fix xt_addrtype with IPv6, from Florian Westphal. This required
a new hook for IPv6 functions in the netfilter core to avoid
hard dependencies with the ipv6 subsystem when this match is
only used for IPv4.
* fix connection reuse case in IPVS. Currently, if an reused
connection are directed to the same server. If that server is
down, those connection would fail. Therefore, clear the
connection and choose a new server among the available ones.
* fix possible non-nul terminated string sent to user-space if
ipt_ULOG is used as the default netfilter logging stub, from
Chen Gang.
* fix mark logging of IPv6 packets in xt_LOG, from Michal Kubecek.
This bug has been there since 2.6.26.
* Fix breakage ip_vs_sh due to incorrect structure layout for
RCU, from Jan Beulich.

tuntap: forbid changing mq flag for persistent device
We currently allow changing the mq flag (IFF_MULTI_QUEUE) for a persistent
device. This will result a mismatch between the number the queues in netdev and
tuntap. This is because we only allocate a 1q netdevice when IFF_MULTI_QUEUE was
not specified, so when we set the IFF_MULTI_QUEUE and try to attach more queues
later, netif_set_real_num_tx_queues() may fail which result a single queue
netdevice with multiple sockets attached.
Solve this by disallowing changing the mq flag for persistent device.

We must clear IPCB in ip_tunnel_xmit() sooner in case dst_link_failure()

GFS2: Use single-block reservations for directories
This patch changes the multi-block allocation code, such that
directory inodes only get a single block reserved in the bitmap.
That way, the bitmaps are more tightly packed together, and there
are fewer spans of free blocks for in-use block reservations.
This means it takes less time to find a free span of blocks in the
bitmap, which speeds things up. This increases the performance of
some workloads by almost 2X. In Nate's mockup.py script (which does
(1) create dir, (2) create dir in dir, (3) create file in that dir)

netfilter: add nf_ipv6_ops hook to fix xt_addrtype with IPv6
Quoting https://bugzilla.netfilter.org/show_bug.cgi?id=812:
[ ip6tables -m addrtype ]
When I tried to use in the nat/PREROUTING it messes up the
routing cache even if the rule didn't matched at all.
[..]
If I remove the --limit-iface-in from the non-working scenario, so just
use the -m addrtype --dst-type LOCAL it works!
This happens when LOCAL type matching is requested with --limit-iface-in,
and the default ipv6 route is via the interface the packet we test
arrived on.
Because xt_addrtype uses ip6_route_output, the ipv6 routing implementation
creates an unwanted cached entry, and the packet won't make it to the
real/expected destination.
Silently ignoring --limit-iface-in makes the routing work but it breaks
rule matching (--dst-type LOCAL with limit-iface-in is supposed to only
match if the dst address is configured on the incoming interface;
without --limit-iface-in it will match if the address is reachable
via lo).
The test should call ipv6_chk_addr() instead. However, this would add
a link-time dependency on ipv6.
There are two possible solutions:
1) Revert the commit that moved ipt_addrtype to xt_addrtype,
and put ipv6 specific code into ip6t_addrtype.
2) add new "nf_ipv6_ops" struct to register pointers to ipv6 functions.
While the former might seem preferable, Pablo pointed out that there
are more xt modules with link-time dependeny issues regarding ipv6,
so lets go for 2).

tcp: bug fix in proportional rate reduction.
This patch is a fix for a bug triggering newly_acked_sacked < 0
in tcp_ack(.).
The bug is triggered by sacked_out decreasing relative to prior_sacked,
but packets_out remaining the same as pior_packets. This is because the
snapshot of prior_packets is taken after tcp_sacktag_write_queue() while
prior_sacked is captured before tcp_sacktag_write_queue(). The problem
is: tcp_sacktag_write_queue (tcp_match_skb_to_sack() -> tcp_fragment)
adjusts the pcount for packets_out and sacked_out (MSS change or other
reason). As a result, this delta in pcount is reflected in
(prior_sacked - sacked_out) but not in (prior_packets - packets_out).
This patch does the following:
1) initializes prior_packets at the start of tcp_ack() so as to
capture the delta in packets_out created by tcp_fragment.
2) introduces a new "previous_packets_out" variable that snapshots
packets_out right before tcp_clean_rtx_queue, so pkts_acked can be
correctly computed as before.
3) Computes pkts_acked using previous_packets_out, and computes
newly_acked_sacked using prior_packets.

MVF is a family while MVF600 is a particular SoC in the family. We
generally prefer to use SoC rather than family name in compatible string
to define a particular type of fec device. And this is how fec_dt_ids
works for all those IMX fec variants. Let's change mvf to mvf600 to
have it work in the same way.

After resetting the device, the driver waits for a signature to be
updated to know that firmware has completed initialization. However, the
call to tg3_poll_fw() is being done too late and we're writing to the
GRC_MODE register before it has completely initialized, causing
contention with firmware. This logic has existed since day one but is

When CONFIG_I2C=m, meaning we can't build the drivers in with I2C support.
Thus don't allow the drivers to be compiled as built-in when CONFIG_I2C=m.
The real fix though is to break the driver apart into a SPI part, an I2C part
and a common part. But that's something for 3.11 while this is something for
3.10/stable.

Merge branch 'i2c/for-current' of git://git./linux/kernel/git/wsa/linux
Pull i2c bugfixes from Wolfram Sang:
"These should have been in rc2 but I missed it due to working on devm
longer than expected.
There is one ID addition, since we are touching the driver anyhow.
And the feature bit documentation is one outcome of a debug session
and will make it easier for users to work around problems. The rest
is typical driver bugfixes."

Since commit c8801a8 (regulator: core: Mark all get and enable calls as
__must_check) we need to check the value returned by 'regulator_enable()'.
Do this check to get rid of the following build warning:
