Pull networking changes from David S. Miller:
1) Fix IPSEC header length calculation for transport mode in ESP. The
issue is whether to do the calculation before or after alignment.
Fix from Benjamin Poirier.
2) Fix regression in IPV6 IPSEC fragment length calculations, from Gao
Feng. This is another transport vs tunnel mode issue.
3) Handle AF_UNSPEC connect()s properly in L2TP to avoid OOPSes. Fix
from James Chapman.
4) Fix USB ASIX driver's reception of full sized VLAN packets, from
Eric Dumazet.
5) Allow drop monitor (and, more generically, all generic netlink
protocols) to be automatically loaded as a module. From Neil
Horman.
Fix up trivial conflict in Documentation/feature-removal-schedule.txt
due to new entries added next to each other at the end. As usual.

mac80211 tries to verify the existence of the current AP by
probing or sending a NULL frame in function
ieee80211_mgd_probe_ap_send. It 1st sends a null frame to the AP,
increments probe_send_count and waits for the ACK to the NULL
frame for a finite duration of time. At times, it happens that by
the time mac80211 gets to increment probe_send_count, the ACK for
the NULL frame transmitted has already been processed. This leads
to a race condition where mac80211 times out waiting for the ACK
for the NULL frame causing unnecessary disconnection with the AP.

Generic netlink searches for -type- formatted aliases when requesting a module to
fulfill a protocol request (i.e. net-pf-16-proto-16-type-<x>, where x is a type
value). However generic netlink protocols have no well defined type numbers,
they have string names. Modify genl_ctrl_getfamily to request an alias in the
format net-pf-16-proto-16-family-<x> instead, where x is a generic string, and
add a macro that builds on the previously added MODULE_ALIAS_NET_PF_PROTO_NAME
macro to allow modules to specifify those generic strings.
Note, l2tp previously hacked together an net-pf-16-proto-16-type-l2tp alias
using the MODULE_ALIAS macro, with these updates we can convert that to use the
PROTO_NAME macro.

RDS code assumes that the struct ib_device dma_device member, which is a
pointer, points to a struct device embedded in a struct pci_dev.
This is not the case for ehca, for example, which is a OF driver, and
makes dma_device point to a struct device embedded in a struct
platform_device.
This will make the system crash when rds_rdma is loaded in a system
with ehca, since it will try to access the bus member of a non-existent
struct pci_dev.
The only reason rds_rdma uses the struct pci_dev is to get the NUMA node
the device is attached to. Using dev_to_node for that is much better,
since it won't assume which bus the infiniband is attached to.

An application may call connect() to disconnect a socket using an
address with family AF_UNSPEC. The L2TP IP sockets were not handling
this case when the socket is not bound and an attempt to connect()
using AF_UNSPEC in such cases would result in an oops. This patch
addresses the problem by protecting the sk_prot->disconnect() call
against trying to unhash the socket before it is bound.
The L2TP IPv4 and IPv6 sockets have the same problem. Both are fixed
by this patch.
The patch also adds more checks that the sockaddr supplied to bind()
and connect() calls is valid.

Since commit ad0081e43a
"ipv6: Fragment locally generated tunnel-mode IPSec6 packets as needed"
the fragment of packets is incorrect.
because tunnel mode needs IPsec headers and trailer for all fragments,
while on transport mode it is sufficient to add the headers to the
first fragment and the trailer to the last.
so modify mtu and maxfraglen base on ipsec mode and if fragment is first
or last.
with my test,it work well(every fragment's size is the mtu)
and does not trigger slow fragment path.
Changes from v1:
though optimization, mtu_prev and maxfraglen_prev can be delete.
replace xfrm mode codes with dst_entry's new frag DST_XFRM_TUNNEL.
add fuction ip6_append_data_mtu to make codes clearer.

Corrects the function that determines the esp payload size. The calculations
done in esp{4,6}_get_mtu() lead to overlength frames in transport mode for
certain mtu values and suboptimal frames for others.
According to what is done, mainly in esp{,6}_output() and tcp_mtu_to_mss(),
net_header_len must be taken into account before doing the alignment
calculation.

There is a race between two __unregister_request() callers: the
reply path and the ceph_osdc_wait_request(). If we get a reply
*and* the timeout expires at roughly the same time, both callers
will try to unregister the request, and the second one will do bad
things.
Simply check if the request is still already unregistered; if so,
return immediately and do nothing.

Move the addition of the authorizer buffer to a connection's
out_kvec out of get_connect_authorizer() and into its caller. This
way, the caller--prepare_write_connect()--can avoid adding the
connect header to out_kvec before it has been fully initialized.
Prior to this patch, it was possible for a connect header to be
sent over the wire before the authorizer protocol or buffer length
fields were initialized. An authorizer buffer associated with that
header could also be queued to send only after the connection header
that describes it was on the wire.

In the create_authorizer method for both the mds and osd clients,
the auth_client->ops pointer is blindly dereferenced. There is no
obvious guarantee that this pointer has been assigned. And
furthermore, even if the ops pointer is non-null there is definitely
no guarantee that the create_authorizer or destroy_authorizer
methods are defined.
Add checks in both routines to make sure they are defined (non-null)
before use. Add similar checks in a few other spots in these files
while we're at it.

prepare_write_connect() prepares a connect message, then sets
WRITE_PENDING on the connection. Then *after* this, it calls
prepare_connect_authorizer(), which updates the content of the
connection buffer already queued for sending. It's also possible it
will result in prepare_write_connect() returning -EAGAIN despite the
WRITE_PENDING big getting set.
Fix this by preparing the connect authorizer first, setting the
WRITE_PENDING bit only after that is done.

There are two blocks of code in read_partial_message()--those that
read the header and footer of the message--that can be replaced by a
call to read_partial(). Do that.

From Al Viro <viro@zeniv.linux.org.uk>
Al Viro noticed that we were using a non-cpu-encoded value in
a switch statement in osd_req_encode_op(). The result would
clearly not work correctly on a big-endian machine.

This was an ill-conceived feature that has been removed from Ceph. Do
this gracefully:
- reject attempts to specify a preferred_osd via the ioctl
- stop exposing this information via virtual xattrs
- always fill in -1 for requests, in case we talk to an older server
- don't calculate preferred_osd placements/pgids

We call the destroy function when a cgroup starts to be removed, such as
by a rmdir event.
However, because of our reference counters, some objects are still
inflight. Right now, we are decrementing the static_keys at destroy()
time, meaning that if we get rid of the last static_key reference, some
objects will still have charges, but the code to properly uncharge them
won't be run.
This becomes a problem specially if it is ever enabled again, because now
new charges will be added to the staled charges making keeping it pretty
much impossible.
We just need to be careful with the static branch activation: since there
is no particular preferred order of their activation, we need to make sure
that we only start using it after all call sites are active. This is
achieved by having a per-memcg flag that is only updated after
static_key_slow_inc() returns. At this time, we are sure all sites are
active.
This is made per-memcg, not global, for a reason: it also has the effect
of making socket accounting more consistent. The first memcg to be
limited will trigger static_key() activation, therefore, accounting. But
all the others will then be accounted no matter what. After this patch,
only limited memcgs will have its sockets accounted.
[akpm@linux-foundation.org: move enum sock_flag_bits into sock.h,
document enum sock_flag_bits,
convert memcg_proto_active() and memcg_proto_activated() to test_bit(),
redo tcp_update_limit() comment to 80 cols]

Pull NFS client updates from Trond Myklebust:
"New features include:
- Rewrite the O_DIRECT code so that it can share the same coalescing
and pNFS functionality as the page cache code.
- Allow the server to provide hints as to when we should use pNFS,
and when it is more efficient to read and write through the
metadata server.
- NFS cache consistency updates:
* Use the ctime to emulate a change attribute for NFSv2/v3 so that
all NFS versions can share the same cache management code.
* New cache management code will only look at the change attribute
and size attribute when deciding whether or not our cached data
is still valid or not.
* Don't request NFSv4 post-op attributes on writes in cases such as
O_DIRECT, where we don't care about data cache consistency, or
when we have a write delegation, and know that our cache is still
consistent.
* Don't request NFSv4 post-op attributes on operations such as
COMMIT, where there are no expected metadata updates.
* Don't request NFSv4 directory post-op attributes in cases where
the operations themselves already return change attribute
updates: i.e. operations such as OPEN, CREATE, REMOVE, LINK and
RENAME.
- Speed up 'ls' and friends by using READDIR rather than READDIRPLUS
if we detect no attempts to lookup filenames.
- Improve the code sharing between NFSv2/v3 and v4 mounts
- NFSv4.1 state management efficiency improvements
- More patches in preparation for NFSv4/v4.1 migration functionality."
Fix trivial conflict in fs/nfs/nfs4proc.c that was due to the dcache
qstr name initialization changes (that made the length/hash a 64-bit
union)

xprt_alloc_slot will call rpc_delay() to make the task wait a bit before
retrying when it gets back an -ENOMEM error from xprt_dynamic_alloc_slot.
The problem is that rpc_delay will clear the task->tk_status, causing
call_reserveresult to abort the task.
The solution is simply to let call_reserveresult handle the ENOMEM error
directly.

It's easily possible for these allocations to fail since we're using
GFP_NOWAIT here. We don't want to spam the logs with warnings about
