ixgbe: Fix memory leak in ixgbe when receiving traffic on DDP enabled rings
This patch fixes a memory leak that was introduced in the 3.4 kernel. The
leak occurred when FCoE was enabled and traffic was passed over the FCoE
rings reserved for FCoE. The memory leak was due to us not populating the
compound page information on the order 1 pages needed for FCoE.

skb_linearize(skb) possibly rearranges the skb internal data and then changes

was assigned skb->data before invoking skb_linearise(skb) must be re-assigned.
In the current tt_query message handling code this is not done and therefore, in
case of skb linearization, the pointer used to handle the packet header ends up

ixgbe: Fix PHC loophole allowing misconfiguration of increment register
This patch fixes a potential hole when configuring the cycle counter used to
generate the nanosecond time clock. This clock is based off of the SYSTIME
registers along with the TIMINCA registers. The TIMINCA register determines
the increment to be added to the SYSTIME registers every DMA clock tick. This
register needs to be reconfigured whenever the link-speed changes. However,
the value calculated stays the same when link is down and when link is up.
Misconfiguration can occur if the link status changes due to a reset, which
causes the TIMINCA register to be reset. This reset puts the device in an
unstable state where the SYSTIME registers stop incrementing and the PTP
protocol does not function.
The solution is to double check the TIMINCA value and always reset the value
if the register is zero. This prevents a misconfiguration bug that halts the
PHC.

net: remove skb_orphan_try()
Orphaning skb in dev_hard_start_xmit() makes bonding behavior
unfriendly for applications sending big UDP bursts : Once packets
pass the bonding device and come to real device, they might hit a full
qdisc and be dropped. Without orphaning, the sender is automatically
throttled because sk->sk_wmemalloc reaches sk->sk_sndbuf (assuming
sk_sndbuf is not too big)
We could try to defer the orphaning adding another test in
dev_hard_start_xmit(), but all this seems of little gain,
now that BQL tends to make packets more likely to be parked
in Qdisc queues instead of NIC TX ring, in cases where performance
matters.

hardware doesn't provide CHECKSUM_COMPLETE support in its cqe.
Then, if IP/L4 checksumming was done by the hardware, set

netpoll: fix netpoll_send_udp() bugs
Bogdan Hamciuc diagnosed and fixed following bug in netpoll_send_udp() :
"skb->len += len;" instead of "skb_put(skb, len);"
Meaning that _if_ a network driver needs to call skb_realloc_headroom(),
only packet headers would be copied, leaving garbage in the payload.
However the skb_realloc_headroom() must be avoided as much as possible
since it requires memory and netpoll tries hard to work even if memory
is exhausted (using a pool of preallocated skbs)
It appears netpoll_send_udp() reserved 16 bytes for the ethernet header,
which happens to work for typicall drivers but not all.
Right thing is to use LL_RESERVED_SPACE(dev)
(And also add dev->needed_tailroom of tailroom)
This patch combines both fixes.

is needed to recover from some rare beacon stuck during stress testing.
Before the STA is associated/IBSS had started beaconing, PLL4(0x1618c)
always seem to have zero even though we had configured PLL3(0x16188) to
query about PLL's locking status. When we keep on polling infinitely PLL4's
8th bit(ie check for PLL locking measurements is done), machine hangs
due to softlockup.

bonding: Fix corrupted queue_mapping
In the transmit path of the bonding driver, skb->cb is used to
stash the skb->queue_mapping so that the bonding device can set its
own queue mapping. This value becomes corrupted since the skb->cb is
also used in __dev_xmit_skb.
When transmitting through bonding driver, bond_select_queue is
called from dev_queue_xmit. In bond_select_queue the original
skb->queue_mapping is copied into skb->cb (via bond_queue_mapping)
and skb->queue_mapping is overwritten with the bond driver queue.
Subsequently in dev_queue_xmit, __dev_xmit_skb is called which writes
the packet length into skb->cb, thereby overwriting the stashed
queue mappping. In bond_dev_queue_xmit (called from hard_start_xmit),
the queue mapping for the skb is set to the stashed value which is now
the skb length and hence is an invalid queue for the slave device.
If we want to save skb->queue_mapping into skb->cb[], best place is to
add a field in struct qdisc_skb_cb, to make sure it wont conflict with
other layers (eg : Qdiscc, Infiniband...)
This patchs also makes sure (struct qdisc_skb_cb)->data is aligned on 8
bytes :
netem qdisc for example assumes it can store an u64 in it, without
misalignment penalty.
Note : we only have 20 bytes left in (struct qdisc_skb_cb)->data[].
The largest user is CHOKe and it fills it.

drm/ttm: Fix buffer object metadata accounting regression v2
A regression was introduced in the 3.3 rc series, commit
"drm/ttm: simplify memory accounting for ttm user v2",
causing the metadata of buffer objects created using the ttm_bo_create()
function to be accounted twice.
That causes massive leaks with the vmwgfx driver running for example
SpecViewperf Catia-03 test 2, eventually killing the app.
Furthermore, the same commit introduces a regression where
metadata accounting is leaked if a buffer object is
initialized with an illegal size. This is also fixed with this commit.

drm: increase DRM_OBJECT_MAX_PROPERTY to 24
Before Kernel 3.5, no one was checking for the return value of
drm_connector_attach_property, so we never noticed that we were unable
to create some properties. Commit "drm: WARN() when
drm_connector_attach_property fails" added a WARN when we fail to
create a property, and the transition from "connector properties" to
"object properties" changed the warning message a little bit.
On i915 machines with many TV connectors we hit the maximum number of
properties (since each TV connector uses a lot of properties), so we
get a few backtraces in our logs. This commit increases the maximum
number of properties to 24 hoping we'll have enough room for
everybody.
Chris suggested that we convert this code to "lists", but I believe
this conversion can come after we make sure people's dmesgs are not
spammed by our driver.

rndis_wlan: fix matching bssid check in rndis_check_bssid_list()
rndis_check_bssid_list() originally tried to check if bssid->mac and
match_bssid are equal using compare_ether_addr() when it should use
!compare_ether_addr(). This check was added by commit
b5257c952dda24df7078c74b7b811b44c6e49206 as part of workaround for
hardware issue.
Commit
2e42e4747ea72943c21551d8a206b51a9893b1e0 that replaced
compare_ether_addr with ether_addr_equal relieved that this compare
to be inverse of what it should be.
Compare was added as response to hardware bug, where bssid-list does
not contain BSSID and other information of currently connected AP
(spec insists that device must provide this information in the list
when connected). Lack bssid-data on current connection then causes
WARN_ON somewhere in cfg80211. Workaround was to check if bssid-list
returns current bssid and if it does not, manually construct bssid
information in other ways. And this workaround worked, with inverse
check. Which must mean that when hardware is experiencing the problem,
it's actually returning empty bssid-list and this check didn't make
any difference for workaround.
However inverse check causes workaround be activated when bssid-list
returns only entry, currently connected BSSID. That does not cause
problems in itself, just slightly more inaccurate information in
scan-list.

After this splat, RTNL is locked and reboot is needed.
We must call cond_resched() to avoid this, even holding RTNL.

net: Reorder initialization in ip_route_output to fix gcc warning
If I build with W=1, for every file that includes <net/route.h>, I get the warning
include/net/route.h: In function 'ip_route_output':
include/net/route.h:135:3: warning: initialized field overwritten [-Woverride-init]
include/net/route.h:135:3: warning: (near initialization for 'fl4') [-Woverride-init]
(This is with "gcc (Debian 4.6.3-1) 4.6.3")
A fix seems pretty trivial: move the initialization of .flowi4_tos
earlier. As far as I can tell, this has no effect on code generation.

virtio-net: fix a race on 32bit arches
commit
3fa2a1df909 (virtio-net: per cpu 64 bit stats (v2)) added a race
on 32bit arches.
We must use separate syncp for rx and tx path as they can be run at the
same time on different cpus. Thus one sequence increment can be lost and
readers spin forever.
