ASoC: Fix SSM2602 device identification
Another fix for v3.17, fixing device identification after the split out
of the I2C and SPI code.

The correct type (SSM2602/SSM2603/SSM2604) is passed down
from the ssm2602_spi_probe()/ssm2602_spi_probe() functions,
so use that instead of hardcoding it to SSM2602 in
ssm2602_probe().

We try to write index registers into cache when we write an index
register, but we change the reg value before updating the cache.
As a result, the cache is never be updated. This patch will fix
this issue.

cpu_dai->dev in fsl_ssi_set_dai_fmt().

Since we cannot make sure the 'params->num_regs' will always be none
zero here, and then if it equals to zero, the kmemdup() will return
ZERO_SIZE_PTR, which equals to ((void *)16).
So this patch fix this with just doing the zero check before calling
kmemdup().

2) Handle full sized 802.1ad frames in bnx2 and tg3 drivers properly,
from Vlad Yasevich.
3) Don't sleep while holding tx_clean_lock in netxen driver, fix from
Manish Chopra.
4) Certain kinds of ipv6 routes can end up endlessly failing the route
validation test, causing it to be re-looked up over and over again.
This particularly kills input route caching in TCP sockets. Fix
from Hannes Frederic Sowa.
5) netvsc_start_xmit() has a use-after-free access to skb->len, fix
from K Y Srinivasan.
6) Fix matching of inverted containers in ematch module, from Ignacy
Gawędzki.
7) Aggregation of GRO frames via SKB ->frag_list for linear skbs isn't
handled properly, regression fix from Eric Dumazet.
8) Don't test return value of ipv4_neigh_lookup(), which returns an
error pointer, against NULL. From WANG Cong.
9) Fix an old regression where we mistakenly allow a double add of the
same tunnel. Fixes from Steffen Klassert.
10) macvtap device delete and open can run in parallel and corrupt lists
etc., fix from Vlad Yasevich.
11) Fix build error with IPV6=m NETFILTER_XT_TARGET_TPROXY=y, from Pablo

The xxx_clear_bp() is used to halt the firmware. It only necessary
for updating the new firmware. Besides, depend on the version of
the current firmware, it may have problem to halt the firmware
directly. Finally, halt the firmware would let the firmware code
useless, and the bugs which are fixed by the firmware would occur.

This driver, similar to tg3, has a check that will
cause full sized 802.1ad frames to be dropped. The
frame will be larger then the standard mtu due to the
presense of vlan header that has not been stripped.
The driver should not drop this frame and should process
it just like it does for 802.1q.

When receiving a vlan-tagged frame that still contains
a vlan header, the length of the packet will be greater
then MTU+ETH_HLEN since it will account of the extra
vlan header. TG3 checks this for the case for 802.1Q,
but not for 802.1ad. As a result, full sized 802.1ad
frames get dropped by the card.
Add a check for 802.1ad protocol when receving full
sized frames.

Eric Dumazet noticed that all no-nonexthop or no-gateway routes which
are already marked DST_HOST (e.g. input routes routes) will always be
invalidated during sk_dst_check. Thus per-socket dst caching absolutely
had no effect and early demuxing had no effect.
Thus this patch removes rt6i_genid: fn_sernum already gets modified during
add operations, so we only must ensure we mutate fn_sernum during ipv6
address remove operations. This is a fairly cost extensive operations,
but address removal should not happen that often. Also our mtu update
functions do the same and we heard no complains so far. xfrm policy
changes also cause a call into fib6_flush_trees. Also plug a hole in
rt6_info (no cacheline changes).
I verified via tracing that this change has effect.

In commit 8a29111c7ca6 ("net: gro: allow to build full sized skb")
I added a regression for linear skb that traditionally force GRO
to use the frag_list fallback.
Erez Shitrit found that at most two segments were aggregated and
the "if (skb_gro_len(p) != pinfo->gso_size)" test was failing.
This is because pinfo at this spot still points to the last skb in the
chain, instead of the first one, where we find the correct gso_size
information.

ipv6: Return an error when adding an already existing tunnel
The ipv6 tunnel locate functions should not return an existing
tunnel if create is true. Otherwise it is possible to add the
same tunnel multiple times without getting an error.
All our ipv6 tunnels have this bug from the very beginning.
Only the sit tunnel was fixed some years ago with:
commit 8db99e57175 ("sit: Fail to create tunnel, if it already exists").
This patchset fixes the remaining ipv6 tunnels.

When the HCA is configured in SRIOV IB mode (that is, at least one of
the ports is IB) and the probe_vf module param isn't specified,
mlx4_init_one() failed because of the following condition:
if (ib_ports && (num_vfs_argc > 1 || probe_vfs_argc > 1)) {
.....
}
The root cause for that is a mistake in the initialization of num_vfs_argc
and probe_vfs_argc. When num_vfs / probe_vf aren't given, their argument
count counterpart should be 0, fix that.

2) Remove unnecessary spinlock_bh in the destroy path of the nf_tables
rbtree set type from rcu_callback context.
3) Fix another lockdep splat in rhashtable. None of the callers hold
a mutex when calling rhashtable_destroy.
4) Fix duplicated error reporting from nfnetlink when aborting and

We have to wait until the full batch has been processed to deliver the
netlink error messages to userspace. Otherwise, we may deliver
duplicated errors to userspace in case that we need to abort and replay
the transaction if any of the required modules needs to be autoloaded.
A simple way to reproduce this (assumming nft_meta is not loaded) with
the following test file:
add table filter
add chain filter test
add chain bad test # intentional wrong unexistent table
add rule filter test meta mark 0
Then, when trying to load the batch:
# nft -f test
test:4:1-19: Error: Could not process rule: No such file or directory
add chain bad test
^^^^^^^^^^^^^^^^^^^
test:4:1-19: Error: Could not process rule: No such file or directory
add chain bad test
^^^^^^^^^^^^^^^^^^^
The error is reported twice, once when the batch is aborted due to
missing nft_meta and another when it is fully processed.

No need for rht_dereference() from rhashtable_destroy() since the
existing callers don't hold the mutex when invoking this function
from:
1) Netlink, this is called in case of memory allocation errors in the
initialization path, no nl_sk_hash_lock is held.
2) Netfilter, this is called from the rcu callback, no nfnl_lock is
held either.
I think it's reasonable to assume that the caller has to make sure
that no hash resizing may happen before releasing the bucket array.
Therefore, the caller should be responsible for releasing this in a
safe way, document this to make people aware of it.
This resolves a rcu lockdep splat in nft_hash:

The sets are released from the rcu callback, after the rule is removed
from the chain list, which implies that nfnetlink cannot update the
rbtree and no packets are walking on the set anymore. Thus, we can get
rid of the spinlock in the set destroy path there.

In macvtap device delete and open calls can race and
this causes a list curruption of the vlan queue_list.
The race intself is triggered by the idr accessors
that located the vlan device. The device is stored
into and removed from the idr under both an rtnl and
a mutex. However, when attempting to locate the device
in idr, only a mutex is taken. As a result, once cpu
perfoming a delete may take an rtnl and wait for the mutex,
while another cput doing an open() will take the idr
mutex first to fetch the device pointer and later take
an rtnl to add a queue for the device which may have
just gotten deleted.
With this patch, we now hold the rtnl for the duration
of the macvtap_open() call thus making sure that
open will not race with delete.

o Driver is doing memset with zero for total number of stats bytes when
it has already filled some data in the stats buffer, which can overwrite
memory area beyond the length of stats buffer.
o Fix this by initializing stats buffer with zero before filling any data in it.

In qlcnic_83xx_setup_idc_parameters() routine use qlcnic_83xx_flash_read32() API
which takes flash lock internally instead of the lockless version
qlcnic_83xx_lockless_flash_read32().

When we try to add an already existing tunnel, we don't return
an error. Instead we continue and call ip_tunnel_update().
This means that we can change existing tunnels by adding
the same tunnel multiple times. It is even possible to change
the tunnel endpoints of the fallback device.
We fix this by returning an error if we try to add an existing
tunnel.

Pull nfsd bugfix from Bruce Fields:
"This fixes a data corruption bug introduced by the v3.16 xdr encoding
rewrite. I haven't managed to reproduce it myself yet, but it's
apparently not hard to hit given the right workload"
