[ Upstream commit 1512747820367c8b3b8b72035f0f78c62f2bf1e9 ]
commit df8ef8f3aaa6692970a436204c4429210addb23a
macvlan: add FDB bridge ops and macvlan flags
added a flags field to macvlan, which can be
controlled from userspace.
The idea is to make the interface future-proof
so we can add flags and not new fields.
However, flags value isn't validated, as a result,
userspace can't detect which flags are supported.

commit 2dfca312a91631311c1cf7c090246cc8103de038 upstream.
brcm80211 cannot handle sending frames with CCK rates as part of an
A-MPDU session. Other drivers may have issues too. Set the flag in all
drivers that have been tested with CCK rates.
This fixes a reported brcmsmac regression introduced in
commit ef47a5e4f1aaf1d0e2e6875e34b2c9595897bef6

commit 19c361608ce3e73f352e323262f7e0a8264be3af upstream.
The PLL hang workaround is required only for AR9330 and
AR9340. This issue was first observed on an AP121 and the WAR
is enabled for AR9340 also (DB120 etc.), since it uses a PLL
design identical to AR9330. This is not required for AR9485 and AR9550.
Various bugs have been reported regarding this:

commit d2e9fc141e2aa21f4b35ee27072d84e9aa6e2ba0 upstream.
ath9k_htc adds padding between the 802.11 header and the payload during
TX by moving the header. When handing the frame back to mac80211 for TX
status handling the header is not moved back into its original position.
This can result in a too small skb headroom when entering ath9k_htc
again (due to a soft retransmission for example) causing an
skb_under_panic oops.
Fix this by moving the 802.11 header back into its original position
before returning the frame to mac80211 as other drivers like rt2x00
or ath5k do.

before calling some other functions that teardown interface. To fix
just check ctx->vif on iwl_chswitch_done(). We should not call
ieee80211_chswitch_done() as channel switch works were already canceled
by mac80211 in ieee80211_do_stop() -> ieee80211_mgd_stop().

commit a2d0909a687b4d250cc2b7481072e361678745ba upstream.
As the firmware API has changed significantly and we don't
have support code for the old APIs, bump the version to be
able to release the version 7 API firmware. Unfortunately
this means that the driver in 3.9 and 3.10 can't work, but
that's still better than crashing the device/driver there.

commit 9116a3683902583a302ac5dcb283416d504d9bb4 upstream.
In multicast, there is no retries nor RTS since there is no
specific recipient that can ACK or send CTS. This means
that we must not use the rate scale table for multicast
frames.
This true for any frame that doesn't have a valid
ieee80211_sta pointer.

commit 86a91ec757338edbce51de5dabd7afb0366f485c upstream.
The AP mode needs to use the MCAST fifo for the MCAST
frames sent after the DTIM. This fifo needs to be
configured with the same parameters as the VOICE FIFO.
A separate SCD queue is mapped to this fifo - the cab_queue
(cab stands for Content After Beacon). This queue isn't
connected to any station, but rather to the MAC context.
This queue should (and is already) be set as the MCAST
queue - this is part of the of MAC context command.

We do not know exactly what the problem is, but we suspect that crossing

Use a custom allocator, using page allocator and 2K fragments for
optimal stack behavior. We might make this allocator generic
in future kernels.

[ Upstream commit 20f0170377264e8449b6987041f0bcc4d746d3ed ]
usbnet doesn't support yet SG, so drivers should not advertise SG or TSO
capabilities, as they allow TCP stack to build large TSO packets that
need to be linearized and might use order-5 pages.
This adds an extra copy overhead and possible allocation failures.
Current code ignore skb_linearize() return code so crashes are even
possible.
Best is to not pretend SG/TSO is supported, and add this again when/if
usbnet really supports SG for devices who could get a performance gain.

commit 953b3539ef9301b8ef73f4b6e2fd824b86aae65a upstream.
This patch fixes an issue wherein association would fail on P2P
interfaces. This happened because we are checking priv->mode
against NL80211_IFTYPE_STATION. While this check is correct for
infrastructure stations, it would fail P2P clients for which mode
is NL80211_IFTYPE_P2P_CLIENT.
Better check would be bss_role which has only 2 values: STA/AP.

commit e2288b66fe7ff0288382b2af671b4da558b44472 upstream.
Since we clear QUEUE_STARTED in rt2x00queue_stop_queue(), following
call to rt2x00queue_pause_queue() reduce to noop, i.e we do not
stop queue in mac80211.
To fix that introduce rt2x00queue_pause_queue_nocheck() function,
which will stop queue in mac80211 directly.
Note that rt2x00_start_queue() explicitly set QUEUE_PAUSED bit.
Note also that reordering operations i.e. first call to
rt2x00queue_pause_queue() and then clear QUEUE_STARTED bit, will race
with rt2x00queue_unpause_queue(), so calling ieee80211_stop_queue()
directly is the only available solution to fix the problem without
major rework.

commit 4928bd2ef8ece262f4f314630219999a91eaa440 upstream.
Currently ath9k_htc will reboot firmware only if interface was
ever started. Which lead to the problem in case where interface
was never started but module need to be reloaded.
This patch will partially fix bug "ath9k_htc: Target is unresponsive"
https://github.com/qca/open-ath9k-htc-firmware/issues/1
Reproduction case:
- plug adapter
- make sure nothing will touch it. Stop Networkmanager or blacklist mac address of this adapter.
- rmmod ath9k_htc; sleep 1; modprobe ath9k_htc

commit dc2a87f519a4d8cb376ab54f22b6b98a943b51ce upstream.
Currently we configure harwdare and clock, only after
interface start. In this case, if we reload module or
reboot PC without configuring adapter, firmware will freeze.
There is no software way to reset adpter.
This patch add initial configuration and set it in
disabled state, to avoid this freeze. Behaviour of this patch
should be similar to: ifconfig wlan0 up; ifconfig wlan0 down.

commit 48bc13072109ea58465542aa1ee31b4e1065468a upstream.
Due to a firmware bug, it crashes when the beacon interval
is smaller than 16. Avoid this by refusing the station state
change creating the AP station, causing mac80211 to abandon
the attempt to connect to the AP, and eventually wpa_s to
blacklist it.

commit bcfb879432094c267c35a7ff75d953d3a66c193a upstream.
Commit a269913c5 entitled "rtlwifi: Rework rtl_lps_leave() and
rtl_lps_enter() to use work queue" has two bugs for USB drivers.
Firstly, the work queue in question was not initialized. Secondly,
the callback routine used by this queue is contained within the
file used for PCI devices. As a result, it is not available for
architectures without PCI hardware.

commit 093b9c71b6e450e375f4646ba86faed0195ec7df upstream.
Due to commit 3683243b ("xen-netfront: use __pskb_pull_tail to ensure
linear area is big enough on RX") xennet_fill_frags() may end up
filling MAX_SKB_FRAGS + 1 fragments in a receive skb, and only reduce
the fragment count subsequently via __pskb_pull_tail(). That's a
result of xennet_get_responses() allowing a maximum of one more slot to
be consumed (and intermediately transformed into a fragment) if the
head slot has a size less than or equal to RX_COPY_THRESHOLD.
Hence we need to adjust xennet_fill_frags() to pull earlier if we
reached the maximum fragment count - due to the described behavior of
xennet_get_responses() this guarantees that at least the first fragment
will get completely consumed, and hence the fragment count reduced.
In order to not needlessly call __pskb_pull_tail() twice, make the
original call conditional upon the pull target not having been reached
yet, and defer the newly added one as much as possible (an alternative
would have been to always call the function right before the call to
xennet_fill_frags(), but that would imply more frequent cases of
needing to call it twice).

[ Upstream commit ece793fcfc417b3925844be88a6a6dc82ae8f7c6 ]
We try to linearize part of the skb when the number of iov is greater than
MAX_SKB_FRAGS. This is not enough since each single vector may occupy more than
one pages, so zerocopy_sg_fromiovec() may still fail and may break the guest
network.
Solve this problem by calculate the pages needed for iov before trying to do
zerocopy and switch to use copy instead of zerocopy if it needs more than
MAX_SKB_FRAGS.
This is done through introducing a new helper to count the pages for iov, and
call uarg->callback() manually when switching from zerocopy to copy to notify
vhost.
We can do further optimization on top.
This bug were introduced from b92946e2919134ebe2a4083e4302236295ea2a73
