Large timeout parameters could result wrong timeout values due to
an overflow at msec to jiffies conversion (reported by Andreas Herz)
[ This patch was mangled by Pablo Neira Ayuso since David Laight and
Eric Dumazet noticed that we were using hardcoded 1000 instead of
MSEC_PER_SEC to calculate the timeout ]

The canonical way to validate if the set bits are in a valid

Pull networking tree from David Miller:
1) ptp_pch driver build broke during this merge window due to missing
slab.h header, fix from Geery Uytterhoeven.
2) If ipset passes in a bogus hash table size we crash because the size
is not validated properly. Compounding this, gcc-4.7 can miscompile
ipset such that even when the user specifies legitimate parameters
the tool passes in an out-of-range size to the kernel.
Fix from Jozsef Kadlecsik.
3) Users have reported that the netdev watchdog can trigger with pch_gbe
devices, and it turns out this is happening because of races in the
TX path of the driver leading to the transmitter hanging. Fix from
Eric Dumazet, reported and tested by Andy Cress.
4) Novatel USB551L devices match the generic class entries for the cdc
ethernet USB driver, but they don't work because they have generic
descriptors and thus need FLAG_WWAN to function properly.
Add the necessary ID table entry to fix this, from Dan Williams.
5) A recursive locking fix in the USBNET driver added a new problem, in
that packet list traversal is now racy and we can thus access
unlinked SKBs and crash.
Avoid this situation by adding some extra state tracking, from Ming
Lei.
6) The rtlwifi conversion to asynchronous firmware loading is racy, fix
by reordering the probe procedure. From Larry Finger.
Fixes: https://bugzilla.kernel.org/show_bug.cgi?id=43187
7) Fix regressions with bluetooth keyboards by notifying userland
properly when the security level changes, from Gustavo Padovan.
8) Bluetooth needs to make sure device connected events are emitted
before other kinds of events, otherwise userspace will think there is
no baseband link yet and therefore abort the sockets associated with
that connection.

codel_should_drop() logic allows a packet being not dropped if queue
size is under max packet size.
In fq_codel, we have two possible backlogs : The qdisc global one, and
the flow local one.
The meaningful one for codel_should_drop() should be the global backlog,
not the per flow one, so that thin flows can have a non zero drop/mark
probability.

The IEEE 802.15.4 Working Group focuses on the standardization of the
bottom two layers of ISO/OSI protocol stack: Physical (PHY) and MAC.
The MAC layer provides access control to a shared channel and reliable
data delivery. The main functions performed by the MAC sublayer are:
association and disassociation, security control, optional star
network topology functions, such as beacon generation and Guaranteed
Time Slots (GTSs) management, generation of ACK frames (if used), and,
finally, application support for the two possible network topologies
described in the standard.
This is an initial commit which describes main data structures needed
for ieee802.15.4 compatible devices representation in the MAC layer.

John Linville says:
Here are three more fixes that some of my developers are desperate to
see included in 3.4...
Johan Hedberg went to some length justifyng the inclusion of these two
Bluetooth fixes:
"The device_connected fix should be quite self-explanatory, but it's
actually a wider issue than just for keyboards. All profiles that do
incoming connection authorization (e.g. headsets) will break without it
with specific hardware. The reason it wasn't caught earlier is that it
only occurs with specific Bluetooth adapters.
As for the security level patch, this fixes L2CAP socket based security
level elevation during a connection. The HID profile needs this (for
keyboards) and it is the only way to achieve the security level
elevation when using the management interface to talk to the kernel
(hence the management enabling patch being the one that exposes this"
The rtlwifi fix addresses a regression related to firmware loading,
as described in kernel.org bug 43187. It basically just moves a hunk
of code to a more appropriate place.

__ratelimit() can be considered an inverted bool test because
it returns true when not ratelimited. Several tests in the
kernel tree use this __ratelimit() function incorrectly.
No net_ratelimit uses are incorrect currently though.
Most uses of net_ratelimit are to log something via printk or
pr_<level>.
In order to minimize the uses of net_ratelimit, and to start
standardizing the code style used for __ratelimit() and net_ratelimit(),
add a net_ratelimited_function() macro and net_<level>_ratelimited()
logging macros similar to pr_<level>_ratelimited that use the global
net_ratelimit instead of a static per call site "struct ratelimit_state".

Commit 4231d47e6fe69f061f96c98c30eaf9fb4c14b96d(net/usbnet: avoid
recursive locking in usbnet_stop()) fixes the recursive locking
problem by releasing the skb queue lock before unlink, but may
cause skb traversing races:
- after URB is unlinked and the queue lock is released,
the refered skb and skb->next may be moved to done queue,
even be released
- in skb_queue_walk_safe, the next skb is still obtained
by next pointer of the last skb
- so maybe trigger oops or other problems
This patch extends the usage of entry->state to describe 'start_unlink'
state, so always holding the queue(rx/tx) lock to change the state if
the referd skb is in rx or tx queue because we need to know if the
refered urb has been started unlinking in unlink_urbs.
The other part of this patch is based on Huajun's patch:
always traverse from head of the tx/rx queue to get skb which is
to be unlinked but not been started unlinking.

way to achieve the security level elevation when using the management
interface to talk to the kernel (hence the management enabling patch
being the one that exposes this issue).
It enables the userspace a security level change when the socket is
already connected and create a way to notify the socket the result of the
request. At the moment of the request the socket is made non writable, if
the request fails the connections closes, otherwise the socket is made
writable again, POLL_OUT is emmited.

Fair Queue Codel packet scheduler
Principles :
- Packets are classified (internal classifier or external) on flows.
- This is a Stochastic model (as we use a hash, several flows might
be hashed on same slot)
- Each flow has a CoDel managed queue.
- Flows are linked onto two (Round Robin) lists,
so that new flows have priority on old ones.
- For a given flow, packets are not reordered (CoDel uses a FIFO)
- head drops only.
- ECN capability is on by default.
- Very low memory footprint (64 bytes per flow)

As Van pointed out, interval/sqrt(count) can be implemented using
multiplies only.
http://en.wikipedia.org/wiki/Methods_of_computing_square_roots#Iterative_methods_for_reciprocal_square_roots
This patch implements the Newton method and reciprocal divide.
Total cost is 15 cycles instead of 120 on my Corei5 machine (64bit
kernel).
There is a small 'error' for count values < 5, but we don't really care.
I reuse a hole in struct codel_vars :
- pack the dropping boolean into one bit
- use 31bit to store the reciprocal value of sqrt(count).

This moves the bus message definition to land together with the
other message types. This message is not used in the kernel but
I'm keeping it anyway.

This switches a horde of NDIS_*-prefixed variables to the RNDIS_*
prefix. Most of them aren't used much and causes no changes.

Switch the hyperv filter and rndis gadget driver to use the same command
enumerators as the other drivers and delete the surplus command codes.

This moves the PnP OID definitions to the RNDIS_* namespace
and puts them in the next falling slot in the list. Oh, the comment
above the PnP defines was referring to some obsolete or out-of-tree
driver so removed it, and removed my own comments telling where each
header segment came from as well, we have moved everything around by
this point anyway.

The NDIS_*-prefixed packet types have equivalent RNDIS_*-
prefixed types, besides nothing in the kernel use these defines.

Let's have a unified table of RNDIS media. We used to have a similar
table with NDIS_* prefix from the gadget driver, but since we're only
using RNDIS in the kernel (IIRC NDIS, non-remote, is for the windows-
internal network drivers so what do we care) let's prefix everything
with RNDIS. Some of the definitions were conflicting, in one of the
defines 0x0B is bearer "CO WAN" and in two others "BPC". Well I took
the majority vote. Two definition of medium 0x09 calls it "wireless
WAN" but one vote for "wireless LAN" but in this case I am sticking
with the minority, "Wide Area Network" does not make much sense in
this case as far as I can tell.
NOTE: latin singular and plural is so screwed up in these defines
that it makes my eyes bleed. But I will not attempt to submit a
patch converting all use of _MEDIA_ to _MEDIUM_ while I can probably
tell from the semantics of the code that RNDIS_MEDIA_STATE_CONNECTED
is most probably (erroneously) referring to a singular, unless it
can return an array of connected media. I suspect these erroneous
plurals are used in documentation and such so I don't want to
mess around with things for no functional change.

Move all RNDIS status codes so they appear in rising order and
in one place of the header file.

The 802_* network OIDs were duplicated, so let's merge them and
use the RNDIS_* prefixed definitions from the hyperV driver.

The RNDIS protocol contains a vast number of Object ID:s (OIDs).
The current definitions had multiple definitions of these ID:s,
let's use the nicely RNDIS_*-prefixed defines from the HyperV
implementation, rename everywhere they're used, and copy+rename
the few that were missing from this list of objects.

The RNDIS status codes are redefined with much stranged ifdeffery
and only one of these codes was used in the hyperv driver, and
there it is very clearly referring to the RNDIS variant, not some
other status. So clarify this by explictly using the RNDIS_*
prefixed status code in the hyperv drivera and delete the
duplicate defines.

As a first step to consolidate the RNDIS implementations, break out
a common file with all the #defines and move it to <linux/rndis.h>.
This also deletes the immediate duplicated defines in the
<linux/rndis.h> file that yields a lot of compilation warnings.
