====================
Two cls_bpf fixes

Found them while doing a review on act_bpf and going over the
cls_bpf code again. Will also address the first issue in act_bpf
as it needs to be fixed there, too.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>

When creating a bpf classifier in tc with priority collisions and
invoking automatic unique handle assignment, cls_bpf_grab_new_handle()
will return a wrong handle id which in fact is non-unique. Usually
altering of specific filters is being addressed over major id, but
in case of collisions we result in a filter chain, where handle ids
address individual cls_bpf_progs inside the classifier.

Issue is, in cls_bpf_grab_new_handle() we probe for head->hgen handle
in cls_bpf_get() and in case we found a free handle, we're supposed
to use exactly head->hgen. In case of insufficient numbers of handles,
we bail out later as handle id 0 is not allowed.

In cls_bpf_modify_existing(), we read out the number of filter blocks,
do some sanity checks, allocate a block on that size, and copy over the
BPF instruction blob from user space, then pass everything through the
classic BPF checker prior to installation of the classifier.

We should reject mismatches here, there are 2 scenarios: the number of
filter blocks could be smaller than the provided instruction blob, so
we do a partial copy of the BPF program, and thus the instructions will
either be rejected from the verifier or a valid BPF program will be run;
in the other case, we'll end up copying more than we're supposed to,
and most likely the trailing garbage will be rejected by the verifier
as well (i.e. we need to fit instruction pattern, ret {A,K} needs to be
last instruction, load/stores must be correct, etc); in case not, we
would leak memory when dumping back instruction patterns. The code should
have only used nla_len() as Dave noted to avoid this from the beginning.
Anyway, lets fix it by rejecting such load attempts.

The device driver has plenty of command buffers available
per channel for channel command communication.
In the extremely rare case when there is no command buffer
available, return a NULL pointer and issue a warning
in the kernel log. The caller handles the case when
a NULL pointer is encountered and returns an error.

In the case the wait for command buffer is possible
(because no lock is held as in the OSN case), still wait
until a channel command buffer is available.

When registering a mdio bus, Linux assumes than every port has a PHY and tries
to scan it. If a switch port has no PHY registered, DSA will fail to register
the slave MII bus. To fix this, set the slave MII bus PHY mask to the switch
PHYs mask.

As an example, if we use a Marvell MV88E6352 (which is a 7-port switch with no
registered PHYs for port 5 and port 6), with the following declared names:

	static struct dsa_chip_data switch_cdata = {
		[...]
		.port_names[0] = "sw0",
		.port_names[1] = "sw1",
		.port_names[2] = "sw2",
		.port_names[3] = "sw3",
		.port_names[4] = "sw4",
		.port_names[5] = "cpu",
	};

DSA will fail to create the switch instance. With the PHY mask set for the
slave MII bus, only the PHY for ports 0-4 will be scanned and the instance will
be successfully created.

* one fix for rfkill while scheduled scan is running.
  Linus's system hit this issue. WiFi would be unavailable
  after this has happpened because of bad state in cfg80211.

When we have an active scheduled scan, and the RFKILL
interrupt kicks in, the stack will cancel the scheduled
scan as part of the down flow. But cancelling scheduled
scan usually implies sending a command to the firwmare
which has been killed as part of the RFKILL interrupt
handling.
Because of that, we returned an error to mac80211 when
it asked to stop the scheduled scan and didn't notify the
end of the scheduled scan. Besides a fat warning, this led
to a situation in which cfg80211 would refuse any new scan
request.

To disentangle this, fake that the scheduled scan has been
stopped without sending the command to the firwmare, return
0 after having properly let cfg80211 know that the scan
has been cancelled.

This is basically the same as:

Pull ARM SoC fixes from Olof Johansson:
 "We've been sitting on our fixes branch for a while, so this batch is
  unfortunately on the large side.

  A lot of these are tweaks and fixes to device trees, fixing various
  bugs around clocks, reg ranges, etc.  There's also a few defconfig
  updates (which are on the late side, no more of those).

  All in all the diffstat is bigger than ideal at this time, but nothing
  in here seems particularly risky"
