Pull networking fixes from David Miller:
1) L2TP doesn't get autoloaded when you try to open an L2TP socket due
to a missing module alias, fix from Benjamin LaHaise.
2) Netlabel and RDS should propagate gfp flags given to them by
callers, fixes from Dan Carpeneter.
3) Recursive locking fix in usbnet wasn't bulletproof and can result in
objects going away mid-flight due to races, fix from Ming Lei.
4) Fix up some confusion about a bool module parameter in netfilter's
iptable_filter and ip6table_filter, from Rusty Russell.
5) If SKB recycling is used via napi_reuse_skb() we end up with
different amounts of headroom reserved than we had at the original
SKB allocation. Fix from Eric Dumazet.
6) Fix races in TG3 driver ring refilling, from Michael Chan.
7) We have callbacks for IPSEC replay notifiers, but some call sites
were not using the ops method and instead were calling one of the
implementations directly. Oops. Fix from Steffen Klassert.
8) Fix IP address validation properly in the bonding driver, the
previous fix only works with netlink where the subnet mask and IP
address are changed in one atomic operation. When 'ifconfig' ioctls
are used the IP address and the subnet mask are changed in two
distinct operations. Fix from Andy Gospodarek.

Pull NFS client updates for Linux 3.4 from Trond Myklebust:
"New features include:
- Add NFS client support for containers.
This should enable most of the necessary functionality, including
lockd support, and support for rpc.statd, NFSv4 idmapper and
RPCSEC_GSS upcalls into the correct network namespace from which
the mount system call was issued.
- NFSv4 idmapper scalability improvements
Base the idmapper cache on the keyring interface to allow
concurrent access to idmapper entries. Start the process of
migrating users from the single-threaded daemon-based approach to
the multi-threaded request-key based approach.
- NFSv4.1 implementation id.
Allows the NFSv4.1 client and server to mutually identify each
other for logging and debugging purposes.
- Support the 'vers=4.1' mount option for mounting NFSv4.1 instead of
having to use the more counterintuitive 'vers=4,minorversion=1'.
- SUNRPC tracepoints.
Start the process of adding tracepoints in order to improve
debugging of the RPC layer.
- pNFS object layout support for autologin.
Important bugfixes include:
- Fix a bug in rpc_wake_up/rpc_wake_up_status that caused them to
fail to wake up all tasks when applied to priority waitqueues.
- Ensure that we handle read delegations correctly, when we try to
truncate a file.
- A number of fixes for NFSv4 state manager loops (mostly to do with
delegation recovery)."

The following patch aimed to resolve an issue where secondary, tertiary,
etc. addresses added to bond interfaces could overwrite the
bond->master_ip and vlan_ip values.
commit 917fbdb32f37e9a93b00bb12ee83532982982df3
Author: Henrik Saavedra Persson <henrik.e.persson@ericsson.com>
Date: Wed Nov 23 23:37:15 2011 +0000
bonding: only use primary address for ARP
That patch was good because it prevented bonds using ARP monitoring from
sending frames with an invalid source IP address. Unfortunately, it
didn't always work as expected.
When using an ioctl (like ifconfig does) to set the IP address and
netmask, 2 separate ioctls are actually called to set the IP and netmask
if the mask chosen doesn't match the standard mask for that class of
address. The first ioctl did not have a mask that matched the one in
the primary address and would still cause the device address to be
overwritten. The second ioctl that was called to set the mask would
then detect as secondary and ignored, but the damage was already done.
This was not an issue when using an application that used netlink
sockets as the setting of IP and netmask came down at once. The
inconsistent behavior between those two interfaces was something that
needed to be resolved.
While I was thinking about how I wanted to resolve this, Ralf Zeidler
came with a patch that resolved this on a RHEL kernel by keeping a full
shadow of the entries in dev->ifa_list for the bonding device and vlan
devices in the bonding driver. I didn't like the duplication of the
list as I want to see the 'bonding' struct and code shrink rather than
grow, but liked the general idea.
As the Subject indicates this patch drops the master_ip and vlan_ip
elements from the 'bonding' and 'vlan_entry' structs, respectively.
This can be done because a device's address-list is now traversed to
determine the optimal source IP address for ARP requests and for checks
to see if the bonding device has a particular IP address. This code
could have all be contained inside the bonding driver, but it made more
sense to me to EXPORT and call inet_confirm_addr since it did exactly
what was needed.
I tested this and a backported patch and everything works as expected.
Ralf also helped with verification of the backported patch.
Thanks to Ralf for all his help on this.

We need to permanently attach the timeout policy to the conntrack,
otherwise we may apply the custom timeout policy inconsistently.
Without this patch, the following example:
nfct timeout add test inet icmp timeout 100
iptables -I PREROUTING -t raw -p icmp -s 1.1.1.1 -j CT --timeout test
Will only apply the custom timeout policy to outgoing packets from
1.1.1.1, but not to reply packets from 2.2.2.2 going to 1.1.1.1.
To fix this issue, this patch modifies the current logic to attach the
timeout policy when the first packet is seen (which is when the
conntrack entry is created). Then, we keep using the attached timeout
policy until the conntrack entry is destroyed.

`iptables -p all' uses 0 to match all protocols, while the conntrack
subsystem uses 255. We still need `-p all' to attach the custom
timeout policies for the generic protocol tracker.
Moreover, we may use `iptables -p sctp' while the SCTP tracker is
not loaded. In that case, we have to default on the generic protocol
tracker.
Another possibility is `iptables -p ip' that should be supported
as well. This patch makes sure we validate all possible scenarios.

In write_partial_msg_pages(), every case now does an identical call
to kmap(page). Instead, just call it once inside the CRC-computing
block where it's needed. Move the definition of kaddr inside that
block, and make it a (char *) to ensure portable pointer arithmetic.
We still don't kunmap() it until after the sendpage() call, in case
that also ends up needing to use the mapping.

In write_partial_msg_pages() there is a local variable used to
track the starting offset within a bio segment to use. Its name,
"page_shift" defies the Linux convention of using that name for
log-base-2(page size).
Since it's only used in the bio case rename it "bio_offset". Use it
along with the page_pos field to compute the memory offset when
computing CRC's in that function. This makes the bio case match the
others more closely.

There's not a lot of benefit to zero_page_address, which basically
holds a mapping of the zero page through the life of the messenger
module. Even with our own mapping, the sendpage interface where
it's used may need to kmap() it again. It's almost certain to
be in low memory anyway.
So stop treating the zero page specially in write_partial_msg_pages()
and just get rid of zero_page_address entirely.

CRC's are computed for all messages between ceph entities. The CRC
computation for the data portion of message can optionally be
disabled using the "nocrc" (common) ceph option. The default is
for CRC computation for the data portion to be enabled.
Unfortunately, the code that implements this feature interprets the
feature flag wrong, meaning that by default the CRC's have *not*
been computed (or checked) for the data portion of messages unless
the "nocrc" option was supplied.
Fix this, in write_partial_msg_pages() and read_partial_message().
Also change the flag variable in write_partial_msg_pages() to be
"no_datacrc" to match the usage elsewhere in the file.

assigned appears to be the opposite of what it should be. No

A spinlock is used to protect a value used for selecting an array
index for a string used for formatting a socket address for human
consumption. The index is reset to 0 if it ever reaches the maximum
index value.
Instead, use an ever-increasing atomic variable as a sequence
number, and compute the array index by masking off all but the
sequence number's lowest bits. Make the number of entries in the
array a power of two to allow the use of such a mask (to avoid jumps
in the index value when the sequence number wraps).
The length of these strings is somewhat arbitrarily set at 60 bytes.
The worst-case length of a string produced is 54 bytes, for an IPv6
address that can't be shortened, e.g.:
[1234:5678:9abc:def0:1111:2222:123.234.210.100]:32767
Change it so we arbitrarily use 64 bytes instead; if nothing else
it will make the array of these line up better in hex dumps.
Rename a few things to reinforce the distinction between the number
of strings in the array and the length of individual strings.

Pull kmap_atomic cleanup from Cong Wang.
It's been in -next for a long time, and it gets rid of the (no longer
used) second argument to k[un]map_atomic().
Fix up a few trivial conflicts in various drivers, and do an "evil
merge" to catch some new uses that have come in since Cong's tree.
