3606479593 iwlwifi: mvm: consider P2p device type for firmware dump triggers
When the user really wanted a dump on P2P Client, he
coudln't get it because we checked vif->type but didn't
take vif->p2p into account. Fix that.

b64abcb7da brcmfmac: Change vif_event_lock to spinlock
Change vif_event_lock to spinlock from mutex, since this lock is
used in wait_event_timeout() via vif_event_equals(). This caused
a warning report as below.

As far as I can see, this lock protects regions where updating
structure members, not function calls. Also, since those
regions are not called from interrupt handlers (of course, it
was a mutex), spin_lock is used instead of spin_lock_irqsave.

15dacf880e brcmfmac: Check rtnl_lock is locked when removing interface
Check rtnl_lock is locked in brcmf_p2p_ifp_removed() by passing
rtnl_locked flag. Actually the caller brcmf_del_if() checks whether
the rtnl_lock is locked, but doesn't pass it to brcmf_p2p_ifp_removed().

Without this fix, wpa_supplicant goes softlockup with rtnl_lock
holding (this means all other process using netlink are locked up too)

7711aaf08a ath9k: fix using sta->drv_priv before initializing it
A station pointer can be passed to the driver on tx, before it has been
marked as associated. Since ath9k_sta_state was initializing the entry
too late, it resulted in some spurious crashes.

2690c4c0e8 wil6210: fix wiphy registration sequence
Currently wiphy structure is initialized and registered
in wil_if_alloc, before some information is available such
as MAC address and capabilities. As a result there is a
small chance user space will get incorrect information
from calls such as NL80211_CMD_GET_WIPHY.
Fix this by seperating the registration and moving it
to wil_if_add which is executed later, after all
relevant information is known.

dc90506f14 wil6210: prevent usage of incorrect TX hwtail
txdata->enabled is used in order to determine if the TX vring
is valid. As the data transmit is handled in a different context,
in case txdata->enabled is set before vring->hwtail is updated,
an old or corrupted vring->hwtail can be used.
Protect setting of txdata->enabled and vring->hwtail to prevent a
case where TX vring start handling TX packets before setting
vring->hwtail.

Removal of the disconnect operation will also preserve the lock

ef86f249fa wil6210: change HALP logging category to IRQ
Change the logging category of HALP functions from
MISC to IRQ, since the HALP mechanism is closely
related to interrupts. Both HALP and IRQ create
a heavy load of logging messages when enabled,
so their logging is typically disabled during normal debug
scenarios. Having them in the same logging category
will make it easier to disable logging for both in one go.

The reason is __dev_alloc_skb() may allocate larger buffer than required

This fixes a crash in wlcore because it was relying on a

it does make sense to have the hw pointer here.

97f2645f35 tree-wide: replace config_enabled() with IS_ENABLED()
The use of config_enabled() against config options is ambiguous.  In
practical terms, config_enabled() is equivalent to IS_BUILTIN(), but the
author might have used it for the meaning of IS_ENABLED().  Using
IS_ENABLED(), IS_BUILTIN(), IS_MODULE() etc.  makes the intention
clearer.

This commit replaces config_enabled() with IS_ENABLED() where possible.
This commit is only touching bool config options.

I noticed two cases where config_enabled() is used against a tristate
option:

 - config_enabled(CONFIG_HWMON)
  [ drivers/net/wireless/ath/ath10k/thermal.c ]

 - config_enabled(CONFIG_BACKLIGHT_CLASS_DEVICE)
  [ drivers/gpu/drm/gma500/opregion.c ]

I did not touch them because they should be converted to IS_BUILTIN()
in order to keep the logic, but I was not sure it was the authors'
intention.

76b817f6c9 ath6kl: Unset IFF_LOWER_UP flag on AP mode leave.
When disabling tethering after having enabled it, the ath6kl driver does
not set the IFF_LOWER_UP flag to 0 (carrier off) on the wlan interface.

The upper layers (eg. connman) are not notified of the tethering mode
status change. So, tethering can not be activated anymore.

This patch adds a netif_carrier_off() call when stopping AP mode to fix
the problem.

f3651bae56 ath6kl: Fix wrong regulatory domain disconnection.
One minute after a successful connection, the kernel checks if the
frequency and the channel width are well configured for the country we
are in. (regulatory domain)

ath6kl driver was setting the NL80211_CHAN_HT20 channel without checking
for the HT capabilities. (we should have NL80211_CHAN_NO_HT in our
case because the firmware did not support HT)

This patch adds a check on ht_cap.ht_supported in order to create the
channel corresponding to the firmware capabilities.

270df8f80d ath6kl: Fix WLAN tethering authentication problem.
When enabling WLAN tethering, a new AP is visible and a STA could
connect to it. When the STA tries to authenticate to the newly created
AP, the WPA authentication mechanism is stuck in the 1/4 msg of 4-Way
Handshake.

In ath6kl_rx(), the ath6kl_find_sta() function is looking for the
h_source field of the Ethernet frame header received by the STA. The
datap pointer that points to the Ethernet frame header is incorrect,
and was pointing at the wrong offset in the buffer.

This commit adds a pad_before_data_start offset to set the datap pointer
to the Ethernet frame header. datap->h_source parameter is now really
pointing to the source ethernet address and the authentication process
can continue.

4ca1807815 ath10k: disable wake_tx_queue for older devices
Ideally wake_tx_queue should be used regardless as
it is a requirement for reducing bufferbloat and
implementing airtime fairness in the future.

However some setups (typically low-end platforms
hosting QCA988X) suffer performance regressions
with the current wake_tx_queue implementation.
Therefore disable it unless it is really
beneficial with current codebase (which is when
firmware supports smart pull-push tx scheduling).
