There are many situations where generic HID driver provides some basic level
of support for certain device, but later this support (usually by implementing
vendor-specific extensions of HID protocol) is extended and the support moved
over to a separate (usually per-vendor) specific driver.
This might bring a rather unpleasant suprise for users, as all of a sudden
there is a new config option they have to enable in order to get any support
for their device whatsoever, although previous kernel versions provided basic
support through the generic driver. Which is rightfully seen as a regression.
Fix this by including the entry for a particular device in
hid_have_special_driver[] iff the specific config option has been specified,
and let generic driver handle the device otherwise.
Also make the behavior of hid_scan_report() (where the same decision is being
taken on a per-report level) consistent.
While at it, reshuffle the hid_have_special_driver[] a bit to restore the
alphabetical ordering (first order by config option, and within those
sections order by VID).
This is considered a short-term solution, before generic way of giving
precedence to special drivers and falling back to generic driver is
figured out.
While at it, fixup a missing entry for GFRM driver; thanks to Hans de Geode for
spotting this (and for discovering a few issues in the conversion).

The wifi driver can decide to not provide parts of the station info. For
example, the expected throughput of the station can be omitted when the
used rate control doesn't provide this kind of information.
The B.A.T.M.A.N. V implementation must therefore check the filled bitfield
before it tries to access the expected_throughput of the returned
station_info.

The description of NL80211_CMD_ROAM indicated possibility for a
request to roam issued by user-space. However, it also states that
as not being implemented right now. This has been so since commit
b23aa676ab9d ("cfg80211: connect/disconnect API") added in 2009.
So it seems safe to assume it will not be added any time soon and
thus remove it.

Drivers that initiate roaming while being connected to a network that
uses 802.1X authentication need to inform user space if 802.1X
authentication is further required after roaming.
For example, when using the Fast transition protocol, roaming within
the mobility domain does not require new 802.1X authentication, but
roaming to another mobility domain does.
In addition, some drivers may not support 802.1X authentication
(so it has to be done in user space), while other drivers do.
Add a flag to the roaming notification to indicate if user space is
required to do 802.1X authentication after the roaming or not.
This flag will only be used for networks that use 802.1X
authentication. For networks that do not use 802.1X authentication it
is assumed that no further action is required from user space after
the roaming notification.

Let drivers advertise support for station-mode 4-way handshake
offloading with a new NL80211_EXT_FEATURE_4WAY_HANDSHAKE_STA_PSK flag.
Extend use of NL80211_ATTR_PMK attribute indicating it might be passed
as part of NL80211_CMD_CONNECT command, and contain the PSK (which is
the PMK, hence the name.)
The driver/device is assumed to handle the 4-way handshake by
itself in this case (including key derivations, etc.), instead
of relying on the supplicant.

mac80211 allows to modify the SMPS state of an AP both,
when it is started, and after it has been started. Such a
change will trigger an action frame to all the peers that
are currently connected, and will be remembered so that
new peers will get notified as soon as they connect (since
the SMPS setting in the beacon may not be the right one).
This means that we need to remember the SMPS state
currently requested as well as the SMPS state that was
configured initially (and advertised in the beacon).
The former is bss->req_smps and the latter is
sdata->smps_mode.
Initially, the AP interface could only be started with
SMPS_OFF, which means that sdata->smps_mode was SMPS_OFF
always. Later, a nl80211 API was added to be able to start
an AP with a different AP mode. That code forgot to update
bss->req_smps and because of that, if the AP interface was
started with SMPS_DYNAMIC, we had:
sdata->smps_mode = SMPS_DYNAMIC
bss->req_smps = SMPS_OFF
That configuration made mac80211 think it needs to fire off
an action frame to any new station connecting to the AP in
order to let it know that the actual SMPS configuration is
SMPS_OFF.
Fix that by properly setting bss->req_smps in
ieee80211_start_ap.

When mac80211 changes the channel, it also calls into the driver's
bss_info_changed() callback, e.g. with BSS_CHANGED_IDLE. The driver
may, like iwlwifi does, access more data from bss_info in that case
and iwlwifi accesses the basic_rates bitmap, but if changing from a
band with more (basic) rates to one with fewer, an out-of-bounds
access of the rate array may result.
While we can't avoid having invalid data at some point in time, we
can avoid having it while we call the driver - so set up all the
data before configuring the channel, and then apply it afterwards.

A recent commit to refactor the driver and remove the hw_disabled_flags
field accidentally introduced two regressions. First, we overwrote
pf->flags which removed various key flags including the MSI-X settings.
Additionally, it was intended that we have now two flags,
HW_ATR_EVICT_CAPABLE and HW_ATR_EVICT_ENABLED, but this was not done,
and we accidentally were mis-using HW_ATR_EVICT_CAPABLE everywhere.
This patch adds the missing piece, HW_ATR_EVICT_ENABLED, and safely
updates pf->flags instead of overwriting it.
Without this patch we will have many problems including disabling MSI-X
support, and we'll attempt to use HW ATR eviction on devices which do
not support it.

udp: reduce cache pressure
In the most common use case, many skb fields are not used by recvmsg(), and
the few ones actually accessed lays on cold cachelines, which leads to several
cache miss per packet.
This patch series attempts to reduce such misses with different strategies:
* caching the interesting fields in the scratched space
* avoid accessing at all uninteresting fields
* prefetching
Tested using the udp_sink program by Jesper[1] as the receiver, an h/w l4 rx
hash on the ingress nic, so that the number of ingress nic rx queues hit by the
udp traffic could be controlled via ethtool -L.
The udp_sink program was bound to the first idle cpu, to get more
stable numbers.
On a single numa node receiver:
nic rx queues vanilla patched kernel delta
1 1850 kpps 1850 kpps 0%
2 2370 kpps 2700 kpps 13.9%
16 2000 kpps 2220 kpps 11%
[1] https://github.com/netoptimizer/network-testing/blob/master/src/udp_sink.c
v1 -> v2:
- replaced secpath_reset() with skb_release_head_state()
- changed udp_dev_scratch fields types to u{32,16} variant,

when udp_recvmsg() is executed, on x86_64 and other archs, most skb
fields are on cold cachelines.
If the skb are linear and the kernel don't need to compute the udp
csum, only a handful of skb fields are required by udp_recvmsg().
Since we already use skb->dev_scratch to cache hot data, and
there are 32 bits unused on 64 bit archs, use such field to cache
as much data as we can, and try to prefetch on dequeue the relevant
fields that are left out.
This can save up to 2 cache miss per packet.

Since UDP no more uses sk->destructor, we can clear completely
the skb head state before enqueuing. Amend and use
skb_release_head_state() for that.
All head states share a single cacheline, which is not
normally used/accesses on dequeue. We can avoid entirely accessing
such cacheline implementing and using in the UDP code a specialized
skb free helper which ignores the skb head state.
This saves a cacheline miss at skb deallocation time.

Commit 27ed3cd2ebf4 (cpufreq: conservative: Fix the logic in frequency

load against down_threshold but did not remove the related limit for the
down_threshold value. As a result, down_threshold lower than 11 is not
allowed even though values from 1 to 10 do work correctly too. The
comment ("cannot be lower than 11 otherwise freq will not fall") also
does not apply after removing the substraction.
For this reason, allow down_threshold to take any value from 1 to 99
and fix the related comment.

Considering this case:
1. A program opens a sysfs table file 65535 times, it can increase
validation_count and first increment cause the table to be mapped:
validation_count = 65535
2. AML execution causes "Load" to be executed on the same
table, this time it cannot increase validation_count, so
validation_count remains:
validation_count = 65535
3. The program closes sysfs table file 65535 times, it can decrease
validation_count and the last decrement cause the table to be
unmapped:
validation_count = 0
4. AML code still accessing the loaded table, kernel crash can be
observed.
To prevent that from happening, add a validation_count threashold.
When it is reached, the validation_count can no longer be
incremented/decremented to invalidate the table descriptor (means
preventing table unmappings)
Note that code added in acpi_tb_put_table() is actually a no-op but
changes the warning message into a "warn once" one. Lv Zheng.

report support for the Set Event Mask Page 2 command, but actually do
return an error when trying to use it.

Since these controllers do not support any feature that would require
the event mask page 2 to be modified, it is safe to not send this
command at all. The default value is all bits set to zero.

Pull key subsystem fixes from James Morris:
"Here are a bunch of fixes for Linux keyrings, including:
- Fix up the refcount handling now that key structs use the
refcount_t type and the refcount_t ops don't allow a 0->1
transition.
- Fix a potential NULL deref after error in x509_cert_parse().
- Don't put data for the crypto algorithms to use on the stack.
- Fix the handling of a null payload being passed to add_key().
- Fix incorrect cleanup an uninitialised key_preparsed_payload in
key_update().
- Explicit sanitisation of potentially secure data before freeing.
- Fixes for the Diffie-Helman code"

Commit abb2ea7dfd82 ("compiler, clang: suppress warning for unused
static inline functions") just caused more warnings due to re-defining
the 'inline' macro.
So undef it before re-defining it, and also add the 'notrace' attribute
like the gcc version that this is overriding does.
Maybe this makes clang happier.

This patch fixes two issues:
1) When forwarding on *,G mroutes that are in a vrf, the
kernel was dropping information about the actual incoming
interface when calling ip_mr_forward from ip_mr_input.
This caused ip_mr_forward to send the multicast packet
back out the incoming interface. Fix this by
modifying ip_mr_forward to be handed the correctly
resolved dev.
2) When a unresolved cache entry is created we store
the incoming skb on the unresolved cache entry and
upon mroute resolution from the user space daemon,
we attempt to forward the packet. Again we were
not resolving to the correct incoming device for
a vrf scenario, before calling ip_mr_forward.
Fix this by resolving to the correct interface
and calling ip_mr_forward with the result.

====================
mlx5-updates-2017-06-11
This series provides updates to mlx5 header rewrite feature, from Or Gerlitz.
and three more small updates From maor and eran.
-------
Or says:
Packets belonging to flows which are different by matching may still need
to go through the same header re-writes (e.g set the current routing hop
MACs and issue TTL decrement). To minimize the number of modify header
IDs, we add a cache for header re-write IDs which is keyed by the binary
chain of modify header actions.
The caching is supported for both eswitch and NIC use-cases, where the
actual conversion of the code to use caching comes in separate patches,
one per use-case.
Using a per field mask field, the TC pedit action supports modifying
partial fields. The last patch enables offloading that.
-------
From Maor, update flow table commands layout to the latest HW spec.
From Eran, ethtool connector type reporting updates.

check_for_missing_tx_completions() is called from a timer
task and looking for lost tx packets.
The old implementation accumulate all the lost tx packets
and did not check if those packets were retrieved on a later stage.
This cause to a situation where the driver reset
the device for no reason.
