This is done to improve readability, and so that we can give
the struct a name that will allow us to declare a local
pointer to it in code, instead of having to always redirect
through the link struct to get to it.

Since the kmem cache API doesn't internally allocate
the name but just points to the name that was passed
in we can't use stack memory for it. Move the name
into the transport struct.

As described in my patch series from the other day, we need to
rearrange redirect handling so that the local initiators of packets
(sockets, tunnels, xfrms, etc.) that implement the protocols compute
the route and pass this down into the ipv4/ipv6 routing code.
These changes here do so by implementing a new dst_ops->redirect
method.
No more do we have this funny code that tries several different sets
of routing keys to try and figure out which route the redirect should
actually be applied to.
No more do we have the problem wherein TOS rewriting causes problems
for us.

If the virtual monitor interface is requested
by the driver, it should also be iterated over
when the driver wants to iterate all active
interfaces.
To allow that protect it with the iflist_mtx.

To call cfg80211_get_chan_state() we need to lock
the wdev, so we need to lock the wdev_iter mutex
in cfg80211_can_use_iftype_chan(). This needs to
use nested locking for lockdep.
Also, cfg80211_get_chan_state() doesn't actually
use the rdev, so remove that completely including
the lock assertion that isn't needed.

When sample_idx is set to a value other than -1 it activates
the IEEE80211_TX_CTL_RATE_CTRL_PROBE flag which disables
frame aggregation. To allow frame aggregation during fixed
rate it is necessary to set max_tp_rate, max_tp_rate2 and
max_prob_rate instead of sample_idx.

When drop_unencrypted is enabled and MFP is disabled,
non-robust management frames for not-yet associated STA are dropped.
This isn't visible as many management frames sent from the kernel
have TX_INTFL_DONT_ENCRYPT set and management frames injected
from a monitor vif have TX_CTL_INJECTED so aren't dropped.
But management frames sent from userspace via NL80211_CMD_FRAME
do not have this flag set, so are dropped.
This patch make it always accept non-robust management frames.

Some drivers (iwlegacy, iwlwifi and rt2x00) today use the
bss_conf.last_tsf value. By itself though that value is
completely worthless since it may be ancient. What really
is needed is synchronisation between some device time and
the TSF.
To clarify this, rename bss_conf.last_tsf to sync_tsf and
add sync_device_ts which is obtained from rx_status which
gets a new field device_timestamp for this purpose. This
is intentionally not using the mactime field since that
is used for other things and in IBSS is expected to sync
with the IBSS's TSF which isn't necessarily true for the
device timestamp.
Also, since we have the information and it's useful even
before the connection has been established, give all the
timing details to the driver before authenticating.

Scan receive is rather inefficient when there are
multiple virtual interfaces. We iterate all of the
virtual interfaces and then notify cfg80211 about
each beacon many times.
Redesign scan RX to happen before everything else.
Then we can also get rid of IEEE80211_RX_IN_SCAN
since we don't have to accept frames into the RX
handlers for scanning or scheduled scanning any
more. Overall, this simplifies the code.

Instead of tracking whether or not we're in a

Making the scan_sdata pointer usable with RCU makes
it possible to dereference it in the RX path to see
if a received frame actually matches the interface
that is scanning. This is just preparations, making
the pointer __rcu.

The function building probe-request IEs does not validate the band is
supported before dereferencing it. This can result in a panic when
all bands are traversed, as done during sched-scan start.
Warn when this happens and return an empty probe request. Also fix
sched-scan to not waste memory on unsupported bands.

This patch handles PCID/INVPCID for guests.
Process-context identifiers (PCIDs) are a facility by which a logical processor
may cache information for multiple linear-address spaces so that the processor
may retain cached information when software switches to a different linear
address space. Refer to section 4.10.1 in IA32 Intel Software Developer's Manual
Volume 3A for details.
For guests with EPT, the PCID feature is enabled and INVPCID behaves as running
natively.
For guests without EPT, the PCID feature is disabled and INVPCID triggers #UD.

Commit ca1d72f033 ('PM / Domains: Make it possible to add devices to
inactive domains') introduced possibility to add devices to inactive
power domains and added pm_genpd_dev_need_restore() function which lets
platform core to notify power domain core that the specified device must
be restored (with its runtime_resume() callback) before first use.
This patch adds the pm_genpd_dev_need_restore() call what brings back
the suspend/resume behaviour for the client devices known from the
previous power domain driver (removed by commit 91cfbd4ee0 - 'ARM:
EXYNOS: Hook up power domains to generic power domain infrastructure').
Client device drivers relay on that suspend/resume behaviour, thus this
patch fixes runtime pm operation for client devices.
