This patch lets untrusted VF to create up to 16 VLANs.
It was implemented by increasing I40E_VC_MAX_VLAN_PER_VF up to 16.
Without this patch untrusted VF could create only up to 8 VLANs.

Since commit d52888aa27 ("x86/mm: Move LDT remap out of KASLR region on
5-level paging") kernel doesn't boot with KASAN on 5-level paging machines.
The bug is actually in early_p4d_offset() and introduced by commit
12a8cc7fcf ("x86/kasan: Use the same shadow offset for 4- and 5-level paging")
early_p4d_offset() tries to convert pgd_val(*pgd) value to a physical
address. This doesn't make sense because pgd_val() already contains the
physical address.
It did work prior to commit d52888aa27 because the result of
"__pa_nodebug(pgd_val(*pgd)) & PTE_PFN_MASK" was the same as "pgd_val(*pgd)
& PTE_PFN_MASK". __pa_nodebug() just set some high bits which were masked
out by applying PTE_PFN_MASK.
After the change of the PAGE_OFFSET offset in commit d52888aa27
__pa_nodebug(pgd_val(*pgd)) started to return a value with more high bits
set and PTE_PFN_MASK wasn't enough to mask out all of them. So it returns a
wrong not even canonical address and crashes on the attempt to dereference
it.
Switch back to pgd_val() & PTE_PFN_MASK to cure the issue.

When the offchannel TX wait time expires, send the appropriate event.
Signed-off-by: James Prestwood <james.prestwood@linux.intel.com>
Signed-off-by: Johannes Berg <johannes.berg@intel.com>
cfg80211_remain_on_channel_expired is used to notify userspace when
the remain on channel duration expired by sending an event. There is
no such equivalent to CMD_FRAME, where if offchannel and a duration
is provided, the card will go offchannel for that duration. Currently
there is no way for userspace to tell when that duration expired
apart from setting an independent timeout. This timeout is quite
erroneous as the kernel may not immediately send out the frame
because of scheduling or work queue delays. In testing, it was found
this timeout had to be quite large to accomidate any potential delays.
A better solution is to have the kernel send an event when this
duration has expired. There is already NL80211_CMD_FRAME_WAIT_CANCEL
which can be used to cancel a NL80211_CMD_FRAME offchannel. Using this
command matches perfectly to how NL80211_CMD_CANCEL_REMAIN_ON_CHANNEL
works, where its both used to cancel and notify if the duration has
expired.

The seen_indices variable is u64 and in other parts of the code we
assume mbssid_index_ie[2] can be up to 45, so we should use the 64-bit
versions of BIT, namely, BIT_ULL().

In multiple SSID cases, it takes time to prepare every AP interface
to be ready in initializing phase. If a sta already knows everything it
needs to join one of the APs and sends authentication to the AP which
is not fully prepared at this point of time, AP's channel context
could be NULL. As a result, warning message occurs.
Even worse, if the AP is under attack via tools such as MDK3 and massive
authentication requests are received in a very short time, console will
be hung due to kernel warning messages.
WARN_ON_ONCE() could be a better way for indicating warning messages
without duplicate messages to flood the console.
Johannes: We still need to address the underlying problem, but we
don't really have a good handle on it yet. Suppress the
worst side-effects for now.

If HW advertises it has rate control, we skip all of the
rate control assignments, but sometimes the data we have
here is useful, especially so that we don't have to do
the lookups again on which rates are configured and are
supported.
So do the low rate assignment anyway to help out drivers
that might need it.

Even if we have a station, we currently call rate_control_send_low()
with the NULL station unless further rate control (driver, minstrel)
has been initialized.
Change this so we can use more information about the station to use
a better rate. For example, when we associate with an AP, we will
now use the lowest rate it advertised as supported (that we can)
rather than the lowest mandatory rate. This aligns our behaviour
with most other 802.11 implementations.
To make this possible, we need to also ensure that we have non-zero
rates at all times, so in case we really have *nothing* pre-fill
the supp_rates bitmap with the very lowest mandatory bitmap (11b
and 11a on 2.4 and 5 GHz respectively).
Additionally, hostapd appears to be giving us an empty supported
rates bitmap (it can and should do better, since the STA must have
supported for at least the basic rates in the BSS), so ignore any
such bitmaps that would actually zero out the supp_rates, and in
that case just keep the pre-filled mandatory rates.

Jason reported that the coarse ktime based time getters advance only once
per second and not once per tick as advertised.
The code reads only the monotonic base time, which advances once per
second. The nanoseconds are accumulated on every tick in xtime_nsec up to
a second and the regular time getters take this nanoseconds offset into
account, but the ktime_get_coarse*() implementation fails to do so.
Add the accumulated xtime_nsec value to the monotonic base time to get the
proper per tick advancing coarse tinme.

The packing facility is needed to decode Ethernet meta frames containing
source port and RX timestamping information.
The DSA driver selects CONFIG_PACKING, but the tagger did not, and since
taggers can be now compiled as modules independently from the drivers
themselves, this is an issue now, as CONFIG_PACKING is disabled by
default on all architectures.
