      cfg80211: fix BSS struct IE access races · 9caf0364
      由 Johannes Berg 提交于 
      When a BSS struct is updated, the IEs are currently
overwritten or freed. This can lead to races if some
other CPU is accessing the BSS struct and using the
IEs concurrently.

Fix this by always allocating the IEs in a new struct
that holds the data and length and protecting access
to this new struct with RCU.

      cfg80211: pass a channel definition struct · 683b6d3b
      由 Johannes Berg 提交于 
      Instead of passing a channel pointer and channel type
to all functions and driver methods, pass a new channel
definition struct. Right now, this struct contains just
the control channel and channel type, but for VHT this
will change.

Also, add a small inline cfg80211_get_chandef_type() so
that drivers don't need to use the _type field of the
new structure all the time, which will change.

      cfg80211: remove remain-on-channel channel type · 42d97a59
      由 Johannes Berg 提交于 
      As mwifiex (and mac80211 in the software case) are the
only drivers actually implementing remain-on-channel
with channel type, userspace can't be relying on it.
This is the case, as it's used only for P2P operations
right now.

Rather than adding a flag to tell userspace whether or
not it can actually rely on it, simplify all the code
by removing the ability to use different channel types.
Leave only the validation of the attribute, so that if
we extend it again later (with the needed capability
flag), it can't break userspace sending invalid data.

      mwifiex: process RX packets in SDIO IRQ thread directly · 601216e1
      由 Bing Zhao 提交于 
      ksdioirqd has higher priority than kworker. Process RX packets
in SDIO IRQ thread (ksdioirqd/mmcX) directly instead of deferring
the work to kworker to avoid the extra latency.
This improves TCP throughput 15~20% on an ARM platform with SDIO
2.0 controller.

      mwifiex: add multi-queue support · 47411a06
      由 Avinash Patil 提交于 
      This patch adds support for multiple TX queues inside mwifiex
driver. Four different queues according to WMM access categories
are defined for each virtual interface. When a packet is
received from netdev for transmission, tx pending count for
particular queue is incremented and if tx pending count has
reached upper water-mark, this queue is stopped instead of
stopping all queues. Similarly when a packet is successfully
transmitted from device, tx pending count is decremented per
queue and if pending count falls below lower water-mark, queue
operations are again resumed. This ensures that not all
tranmission is blocked if traffic with particular TOS value
suddenly increases.

Also wake all queues after association/IBSS_join/uAP_BSS_start
to enable traffic on all queues.

      mwifiex: add support for SDIO card reset · d31ab357
      由 Amitkumar Karwar 提交于 
      When command timeout happens due to a bug in firmware/hardware,
the timeout handler just prints some debug information. User is
unable to reload the driver in this case.

Inspired by 9a821f5d "libertas: add sd8686 reset_card support",
this patch adds card reset support for SDIO interface when
command timeout happens. If the SDIO host contoller supports
MMC_POWER_OFF|UP|ON operations, the chip will be reset and the
firmware will be re-downloaded.

      wireless: drivers: make use of WLAN_EID_VENDOR_SPECIFIC · 04b2312a
      由 Arend van Spriel 提交于 
      The include file linux/ieee80211.h contains three definitions for
the same thing in enum ieee80211_eid due to historic changes:

/* Information Element IDs */
enum ieee80211_eid {
    :
    WLAN_EID_WPA = 221,
    WLAN_EID_GENERIC = 221,
    WLAN_EID_VENDOR_SPECIFIC = 221,
    :
};

The standard refers to this as "vendor specific" element so the
other two definitions are better not used. This patch changes the
wireless drivers to use one definition, ie. WLAN_EID_VENDOR_SPECIFIC.

      wireless: use OR operation to set wiphy features · b292219f
      由 Johannes Berg 提交于 
      The next patch will introduce a flag that is set
by default in cfg80211 so drivers and mac80211
need to use |= to set features they have so that
they don't clear the already-set feature.

We could set the flag in wiphy_register() instead
of wiphy_new() to avoid this patch, but then the
drivers couldn't *unset* flags they don't want to
use even though the implementation is generic.
