batman-adv: fix race condition in TT full-table replacement
bug introduced with
cea194d90b11aff7fc289149e4c7f305fad3535a
In the current TT code, when a TT_Response containing a full table is received
from an originator, first the node purges all the clients for that originator in
the global translation-table and then merges the newly received table.
During the purging phase each client deletion is done by means of a call_rcu()
invocation and at the end of this phase the global entry counter for that
originator is set to 0. However the invoked rcu function decreases the global
entry counter for that originator by one too and since the rcu invocation is
likely to be postponed, the node will end up in first setting the counter to 0
and then decreasing it one by one for each deleted client.
This bug leads to having a wrong global entry counter for the related node, say
X. Then when the node with the broken counter will answer to a TT_REQUEST on
behalf of node X, it will create faulty TT_RESPONSE that will generate an
unrecoverable situation on the node that asked for the full table recover.
The non-recoverability is given by the fact that the node with the broken
counter will keep answering on behalf of X because its knowledge about X's state
(ttvn + tt_crc) is correct.
To solve this problem the counter is not explicitly set to 0 anymore and the
counter decrement is performed right before the invocation of call_rcu().

r8169: RxConfig hack for the 8168evl.
The 8168evl (RTL_GIGA_MAC_VER_34) based Gigabyte GA-990FXA motherboards
are very prone to NETDEV watchdog problems without this change. See
https://bugzilla.kernel.org/show_bug.cgi?id=42899 for instance.
I don't know why it *works*. It's depressingly effective though.
For the record:
- the problem may go along IOMMU (AMD-Vi) errors but it really looks
like a red herring.
- the patch sets the RX_MULTI_EN bit. If the 8168c doc is any guide,
the chipset now fetches several Rx descriptors at a time.
- long ago the driver ignored the RX_MULTI_EN bit.
e542a2269f232d61270ceddd42b73a4348dee2bb changed the RxConfig
settings. Whatever the problem it's now labeled a regression.
- Realtek's own driver can identify two different 8168evl devices

sees one. It sucks.

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.

ipv6: Prevent access to uninitialized fib_table_hash via /proc/net/ipv6_route
/proc/net/ipv6_route reflects the contents of fib_table_hash. The proc
handler is installed in ip6_route_net_init() whereas fib_table_hash is
allocated in fib6_net_init() _after_ the proc handler has been installed.
This opens up a short time frame to access fib_table_hash with its pants
down.
fib6_init() as a whole can't be moved to an earlier position as it also
registers the rtnetlink message handlers which should be registered at
the end. Therefore split it into fib6_init() which is run early and
fib6_init_late() to register the rtnetlink message handlers.

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.

bnx2x driver incorrectly sets ip_summed to CHECKSUM_UNNECESSARY on

Our understanding is that if no IP or L4 csum validation was done by the
hardware, we should leave ip_summed as is (CHECKSUM_NONE), since
hardware doesn't provide CHECKSUM_COMPLETE support in its cqe.
Then, if IP/L4 checksumming was done by the hardware, set
CHECKSUM_UNNECESSARY if no error was flagged.

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)

mac80211: stop polling in disassociation
Stop connection monitor poll during disassociation.
This clears the polling flags and if a scan was
deferred it will be run.
Without this fix, if a scan was deferred due to
connection monitoring while disassociation happens,
this scan blocks further scan requests until interface
down/up which causes problems connecting to another AP.

cfg80211: fix potential deadlock in regulatory

reg_set_request_processed() already holds cfg80211_mutex

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.

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.

pinctrl: pinctrl-mxs: Take care of frees if the kzalloc fails
if there is no purecfg , the group pointer is allocated using kzalloc and if it
fails to allocate, we wont free the new_map,
if config is true, we call kmemdup and if it
fails to do so we wont free the allocated group if there is no purecfg.
fix this by doing the frees of new_map pointer and group pointers.

pinctrl: pinctrl-imx: fix incorrect debug message of maps
After create config map, the new_map pointer becomes point to
PIN_MAP_TYPE_CONFIGS_PIN map rather than PIN_MAP_TYPE_MUX_GROUP map any more.
Thus using new_map pointer to display the MUX_GROUP info is not correct.
Using map pointer instead to show the correct MUX_GROUP map info.
Original the debug message is:
imx6q-pinctrl
20e0000.iomuxc: maps: function Yp group MX6Q_PAD_SD3_CMD num 12
After fix it is:
imx6q-pinctrl

a) as we allocate the pinctrl_map structure at imx_dt_node_to_map at line 167, anyway
if its an element, or a num_elements * (sizeof(type)) elements allocated to one single
pointer must be freed only once.
CASE. A)
as new_map is not moved and allocated like,
for (i = 0; i < MAX_ELEMS; i++) {
new_map[i] = kmalloc(numelems * size, GFP_KERNEL);
}
its freed as
for (i = 0; i < MAX_ELEMS; i++) {
kfree(new_map[i]);

CASE. B)

new_map = kmalloc(numelems * size, GFP_KERNEL);
it just needs kfree not as case A's.

pinctrl: nomadik: fix up typo
Commit
a60b57eddaa8af6c02cf7bbeb58ebf82881f08ac
"drivers/gpio: gpio-nomadik: Add support for irqdomains"
changed GPIO offset calculations to have this form:
(gpio % NMK_GPIO_PER_CHIP) except in this one place for
setting sleep mode, where the conversion was all wrong, and
instead mod:ing the GPIO with the IRQ base which does not
make any sense.
So fix this up so we can use sleepmode.
