Array index 'j' is used before limits check.
Suggest put limit check before index use.

We don't delete napi from hash list during module exit. This will

This patch fixes this by doing this in virtnet_free_queues(). And also
don't delete napi in virtnet_freeze() since it will call
virtnet_free_queues() which has already did this.

The rds_iw_update_cm_id function stores a large 'struct rds_sock' object
on the stack in order to pass a pair of addresses. This happens to just
fit withint the 1024 byte stack size warning limit on x86, but just
exceed that limit on ARM, which gives us this warning:
net/rds/iw_rdma.c:200:1: warning: the frame size of 1056 bytes is larger than 1024 bytes [-Wframe-larger-than=]
As the use of this large variable is basically bogus, we can rearrange
the code to not do that. Instead of passing an rds socket into
rds_iw_get_device, we now just pass the two addresses that we have
available in rds_iw_update_cm_id, and we change rds_iw_get_mr accordingly,
to create two address structures on the stack there.

John reported that my previous commit added a regression
on his router.
This is because sender_cpu & napi_id share a common location,
so get_xps_queue() can see garbage and perform an out of bound access.
We need to make sure sender_cpu is cleared before doing the transmit,
otherwise any NIC busy poll enabled (skb_mark_napi_id()) can trigger
this bug.

sysctl has sysctl.net.core.rmem_*/wmem_* parameters which can be
set to incorrect values. Given that 'struct sk_buff' allocates from
rcvbuf, incorrectly set buffer length could result to memory
allocation failures. For example, set them as follows:
# sysctl net.core.rmem_default=64
net.core.wmem_default = 64
# sysctl net.core.wmem_default=64
net.core.wmem_default = 64
# ping localhost -s 1024 -i 0 > /dev/null
This could result to the following failure:

Commit 814d488c6126 ("tcp: fix the timid additive increase on stretch
ACKs") fixed a bug where tcp_cong_avoid_ai() would either credit a
connection with an increase of snd_cwnd_cnt, or increase snd_cwnd, but
not both, resulting in cwnd increasing by 1 packet on at most every
alternate invocation of tcp_cong_avoid_ai().
Although the commit correctly implemented the CUBIC algorithm, which
can increase cwnd by as much as 1 packet per 1 packet ACKed (2x per
RTT), in practice that could be too aggressive: in tests on network
paths with small buffers, YouTube server retransmission rates nearly
doubled.
This commit restores CUBIC to a maximum cwnd growth rate of 1 packet
per 2 packets ACKed (1.5x per RTT). In YouTube tests this restored
retransmit rates to low levels.
Testing: This patch has been tested in datacenter netperf transfers
and live youtube.com and google.com servers.

The recent change to tcp_cong_avoid_ai() to handle stretch ACKs
introduced a bug where snd_cwnd_cnt could accumulate a very large
value while w was large, and then if w was reduced snd_cwnd could be
incremented by a large delta, leading to a large burst and high packet
loss. This was tickled when CUBIC's bictcp_update() sets "ca->cnt =
100 * cwnd".
This bug crept in while preparing the upstream version of
814d488c6126.
Testing: This patch has been tested in datacenter netperf transfers
and live youtube.com and google.com servers.

The commit below introduced an unsafe dereference of
mvmvif->phy_ctxt. It can be NULL even if we hold the mutex.
We can be handling a BT Coex notification while the vif has
already been unassigned. This can happen since the BT Coex
notification is hanled asynchronuously: we can have started
to handle the BT Coex notification trying to acquire the
mutex while the unassign flow already got it. The BT Coex
notification handling will wait for the mutext. I'll get it
later, but then mvmvif->phy_ctxt will be NULL.

The commit below didn't update the max_ht_ampdu_exponent
for the devices listed in iwl-[1-6]000.c which, in result,
became 0 instead of 8K. This reduced the size of the Rx
AMPDU from 64K to 8K which had an impact in the Rx
throughput. One user reported that because of this, his
downstream throughput droppped by a half.

iwl_mvm_stop_roc removes TE only if running flag is set. This is not correct
since this flag is only set when the TE is started.
This resulted in a TE not being removed, when mac80211 believes that there are
no active ROCs.

In certain conditions, mac80211 may ask us to stop a scan (scheduled
or normal) that is not running anymore. This can also happen when we
are doing a different type of scan, for instance, mac80211 can ask us
to stop a scheduled scan when we are running a normal scan, due to
some race conditions. In this case, we would stop the wrong type of
scan and leave everything everything in a wrong state.
To fix this, simply ignore scan stop requests for scans types that are
not running.

The check to avoid the shared antenna was passed the wrong
antenna parameter. It should have checked whether the antenna of
the next column we're considering is allowed and instead it was
passed the current antenna.
This could lead to a wrong choice of the next column in the rs
algorithm and non optimal performance.

A scan abort command failure is not that unusual, since we may try to
send it after the scan has actually completed but before we received
the completed notification from the firmware. The scan abort can also
fail for other reasons, such as a timeout. In such cases, we should
clear things up so the next scans will work again. To do so, don't
return immediately in case of failures, but call
ieee80211_scan_completed() and clear the scan_status flags.

Routine rtl_is_special_data() is supposed to identify packets that need to
use a low bit rate so that the probability of successful transmission is
high. The current version has a bug that causes all IPv6 packets to be
labelled as special, with a corresponding low rate of transmission. A
complete fix will be quite intrusive, but until that is available, all
IPv6 packets are identified as regular.
This patch also removes a magic number.

We dynamically allocate divisor+1 entries for ->ht[] in tc_u_hnode:
ht = kzalloc(sizeof(*ht) + divisor*sizeof(void *), GFP_KERNEL);
So ->ht is supposed to be the last field of this struct, however
this is broken, since an rcu head is appended after it.

Pull sound fixes from Takashi Iwai:
"This is a collection of many small fixes. Most of fixes are for ASoC
drivers, including the fixes of wrong field usages for boolean kctls.
In addition, there is a fix in ASoC core for adding proper locks for
component lists, and a fix for a HD-audio regression by the previous
mono channel fix"

ASoC: Fixes for v4.0
As well as the usual collection of driver specific fixes there's a few
more generic things:
- Lots of fixes from Takashi for drivers using the wrong field in the
control union to communicate with userspace, leading to potential
errors on 64 bit systems.
- A fix from Lars for locking of the lists of devices we maintain,
mostly only likely to trigger during device probe and removal.

Routes without a control must use NULL for the control name. The sn95031
driver uses "NULL" instead in a few places. Previous to commit 5fe5b767dc6f
("ASoC: dapm: Do not pretend to support controls for non mixer/mux widgets")
the DAPM core silently ignored non-NULL controls on non-mixer and non-mux
routes. But starting with that commit it will complain and not add the
route breaking the sn95031 driver in the process.
This patch replaces the incorrect "NULL" control name with NULL to fix the
issue.

Any access to the component_list, codec_list and platform_list needs to be
properly locked by the client_mutex. Otherwise undefined behavior can occur
if the list is modified in one thread and concurrently accessed from another
thread.
This patch adds the missing locking to the debugfs file handlers that
display the registered components, as well as the various components
unregister functions.
Furthermore the client_lock is now held for the whole
snd_soc_instantiate_card() sequence to make sure that component removal does
not race against the card registration.

According to i.MX6 Series Reference Manual, the formula to calculate
the sys clock is
sysclk rate = bclk rate * (div2 + 1) * (7 * psr + 1) * (pm + 1) * 2
Commit aafa85e71a75 ("ASoC: fsl_ssi: Add DAI master mode support for
SSI on i.MX series") added the divisor calculation which relies on
the clk_round_rate(). However, at that time, clk_round_rate() didn't
provide closest clock rates for some cases because it might not use
a correct rounding policy. So using the original formula (pm + 1) for
PM divisor was not able to give us a desired clock rate. And then we
used (pm + 2) to do the trick.
However, the clk-divider driver has been refined a lot since commit
b11d282dbea2 ("clk: divider: fix rate calculation for fractional rates")
Now using (pm + 2) trick would result an incorrect clock rate.
So this patch fixes the problem by removing the useless trick.
