In order to prevent a device from disappearing when a background job was
started, dev_hold() and dev_put() calls were made. During the
stabilization phase of the scan/beacon features, it was later decided
that removing the device while a background job was ongoing was a valid use
case, and we should instead stop the background job and then remove the
device, rather than prevent the device from being removed. This is what
is currently done, which means manually reference counting the device
during background jobs is no longer needed.

Changing the channels is prohibited while a beacon operation is

The ieee802154 layer should be able to scan a set of channels in order
to look for beacons advertizing PANs. Supporting this involves adding
two user commands: triggering scans and aborting scans. The user should
also be notified when a new beacon is received and also upon scan
termination.
A scan request structure is created to list the requirements and to be
accessed asynchronously when changing channels or receiving beacons.

We currently have two forms of operations - small ops and "full" ops
(or just ops). The former does not have pointers for some of the less
commonly used features (namely dump start/done and policy).
The "full" ops, however, still don't contain all the necessary
information. In particular the policy is per command ID, while
do and dump often accept different attributes. It's also not
possible to define different pre_doit and post_doit callbacks
for different commands within the family.
At the same time a lot of commands do not support dumping and
therefore all the dump-related information is wasted space.
Create a new command representation which can hold info about
a do implementation or a dump implementation, but not both at
the same time.
Use this new representation on the command execution path
(genl_family_rcv_msg) as we either run a do or a dump and
don't have to create a "full" op there.

Create a hold_txs atomic variable and increment/decrement it when
relevant, ie. when we want to hold the queue or release it: currently
all the "stopped" situations are suitable, but very soon we will more
extensively use this feature for MLME purposes.
Upon release, the atomic counter is decremented and checked. If it is
back to 0, then the netif queue gets woken up. This makes the whole
process fully transparent, provided that all the users of
ieee802154_wake/stop_queue() now call ieee802154_hold/release_queue()
instead.
In no situation individual drivers should call any of these helpers
manually in order to avoid messing with the counters. There are other
functions more suited for this purpose which have been introduced, such
as the _xmit_complete() and _xmit_error() helpers which will handle all
that for them.
One advantage is that, as no more drivers call the stop/wake helpers
directly, we can safely stop exporting them and only declare the
hold/release ones in a header only accessible to the core.

The internal recvmsg() functions have two parameters 'flags' and 'noblock'
that were merged inside skb_recv_datagram(). As a follow up patch to commit
f4b41f062c ("net: remove noblock parameter from skb_recv_datagram()")
this patch removes the separate 'noblock' parameter for recvmsg().
Analogue to the referenced patch for skb_recv_datagram() the 'flags' and
'noblock' parameters are unnecessarily split up with e.g.
err = sk->sk_prot->recvmsg(sk, msg, size, flags & MSG_DONTWAIT,
flags & ~MSG_DONTWAIT, &addr_len);
or in
err = INDIRECT_CALL_2(sk->sk_prot->recvmsg, tcp_recvmsg, udp_recvmsg,
sk, msg, size, flags & MSG_DONTWAIT,
flags & ~MSG_DONTWAIT, &addr_len);
instead of simply using only flags all the time and check for MSG_DONTWAIT
where needed (to preserve for the formerly separated no(n)block condition).

skb_recv_datagram() has two parameters 'flags' and 'noblock' that are
merged inside skb_recv_datagram() by 'flags | (noblock ? MSG_DONTWAIT : 0)'
As 'flags' may contain MSG_DONTWAIT as value most callers split the 'flags'
into 'flags' and 'noblock' with finally obsolete bit operations like this:
skb_recv_datagram(sk, flags & ~MSG_DONTWAIT, flags & MSG_DONTWAIT, &rc);
And this is not even done consistently with the 'flags' parameter.
This patch removes the obsolete and costly splitting into two parameters
and only performs bit operations when really needed on the caller side.

A latter patch will postpone the delivery_time clearing until the stack
knows the skb is being delivered locally (i.e. calling
skb_clear_delivery_time() at ip_local_deliver_finish() for IPv4
and at ip6_input_finish() for IPv6). That will allow other kernel
forwarding path (e.g. ip[6]_forward) to keep the delivery_time also.
A very similar IPv6 defrag codes have been duplicated in
multiple places: regular IPv6, nf_conntrack, and 6lowpan.
Unlike the IPv4 defrag which is done before ip_local_deliver_finish(),
the regular IPv6 defrag is done after ip6_input_finish().
Thus, no change should be needed in the regular IPv6 defrag
logic because skb_clear_delivery_time() should have been called.
6lowpan also does not need special handling on delivery_time
because it is a non-inet packet_type.
However, cf_conntrack has a case in NF_INET_PRE_ROUTING that needs
to do the IPv6 defrag earlier. Thus, it needs to save the
mono_delivery_time bit in the inet_frag_queue which is similar
to how it is handled in the previous patch for the IPv4 defrag.
This patch chooses to do it consistently and stores the mono_delivery_time
in the inet_frag_queue for all cases such that it will be easier
for the future refactoring effort on the IPv6 reasm code.

compat_ifreq_ioctl() is one of the last users of copy_in_user() and
compat_alloc_user_space(), as it attempts to convert the 'struct ifreq'
arguments from 32-bit to 64-bit format as used by dev_ioctl() and a
couple of socket family specific interpretations.
The current implementation works correctly when calling dev_ioctl(),
inet_ioctl(), ieee802154_sock_ioctl(), atalk_ioctl(), qrtr_ioctl()
and packet_ioctl(). The ioctl handlers for x25, netrom, rose and x25 do
not interpret the arguments and only block the corresponding commands,
so they do not care.
For af_inet6 and af_decnet however, the compat conversion is slightly
incorrect, as it will copy more data than the native handler accesses,
both of them use a structure that is shorter than ifreq.
Replace the copy_in_user() conversion with a pair of accessor functions
to read and write the ifreq data in place with the correct length where
needed, while leaving the other ones to copy the (already compatible)
structures directly.
