      cfg80211: add P2P Device abstraction · 98104fde
      Johannes Berg authored
      
      
      In order to support using a different MAC address
      for the P2P Device address we must first have a
      P2P Device abstraction that can be assigned a MAC
      address.
      
      This abstraction will also be useful to support
      offloading P2P operations to the device, e.g.
      periodic listen for discoverability.
      
      Currently, the driver is responsible for assigning
      a MAC address to the P2P Device, but this could be
      changed by allowing a MAC address to be given to
      the NEW_INTERFACE command.
      
      As it has no associated netdev, a P2P Device can
      only be identified by its wdev identifier but the
      previous patches allowed using the wdev identifier
      in various APIs, e.g. remain-on-channel.

      cfg80211: use wdev in mgmt-tx/ROC APIs · 71bbc994
      Johannes Berg authored
      
      
      The management frame and remain-on-channel APIs will be
      needed in the P2P device abstraction, so move them over
      to the new wdev-based APIs. Userspace can still use both
      the interface index and wdev identifier for them so it's
      backward compatible, but for the P2P Device wdev it will
      be able to use the wdev identifier only.

      cfg80211: stop tracking authenticated state · 95de817b
      Johannes Berg authored
      
      
      To track authenticated state seems to have been
      a design mistake in cfg80211. It is possible to
      have out of band authentication (FT), tracking
      multiple authentications caused more problems
      than it ever helped, and the implementation in
      mac80211 is too complex.
      
      Remove all this complexity, and let userspace
      do whatever it wants to, mac80211 can deal with
      that just fine. Association is still tracked of
      course, but authentication no longer is. Local
      auth state changes are thus no longer of value,
      so ignore them completely.
      
      This will also help implement SAE -- asking the
      driver to do an authentication is now almost
      equivalent to sending an authentication frame,
      with the exception of shared key authentication
      which is still handled completely.

      wireless: Support ht-capabilities over-rides. · 7e7c8926
      Ben Greear authored
      
      
      This allows users to disable features such as HT, HT40,
      and to modify the MCS, AMPDU, and AMSDU settings for
      drivers that support it.
      
      The MCS, AMPDU, and AMSDU features that may be disabled are
      are reported in the phy-info netlink message as a mask.
      
      Attemping to disable features that are not supported will
      take no affect, but will not return errors.  This is to aid
      backwards compatibility in user-space apps that may not be
      clever enough to deal with parsing the the capabilities mask.
      
      This patch only enables the infrastructure.  An additional
      patch will enable the feature in mac80211.

      cfg80211/nl80211: support GTK rekey offload · e5497d76
      Johannes Berg authored
      
      
      In certain circumstances, like WoWLAN scenarios,
      devices may implement (partial) GTK rekeying on
      the device to avoid waking up the host for it.
      
      In order to successfully go through GTK rekeying,
      the KEK, KCK and the replay counter are required.
      
      Add API to let the supplicant hand the parameters
      to the driver which may store it for future GTK
      rekey operations.
      
      Note that, of course, if GTK rekeying is done by
      the device, the EAP frame must not be passed up
      to userspace, instead a rekey event needs to be
      sent to let userspace update its replay counter.

      nl80211: Add notification for dropped Deauth/Disassoc · cf4e594e
      Jouni Malinen authored
      
      
      Add a new notification to indicate that a received, unprotected
      Deauthentication or Disassociation frame was dropped due to
      management frame protection being in use. This notification is
      needed to allow user space (e.g., wpa_supplicant) to implement
      SA Query procedure to recover from association state mismatch
      between an AP and STA.
      
      This is needed to avoid getting stuck in non-working state when MFP
      (IEEE 802.11w) is used and a protected Deauthentication or
      Disassociation frame is dropped for any reason. After that, the
      station would silently discard any unprotected Deauthentication or
      Disassociation frame that could be indicating that the AP does not
      have association for the STA (when the Reason Code would be 6 or 7).
      IEEE Std 802.11w-2009, 11.13 describes this recovery mechanism.

      cfg80211: Add local-state-change-only auth/deauth/disassoc · d5cdfacb
      Jouni Malinen authored
      
      
      cfg80211 is quite strict on allowing authentication and association
      commands only in certain states. In order to meet these requirements,
      user space applications may need to clear authentication or
      association state in some cases. Currently, this can be done with
      deauth/disassoc command, but that ends up sending out Deauthentication
      or Disassociation frame unnecessarily. Add a new nl80211 attribute to
      allow this sending of the frame be skipped, but with all other
      deauth/disassoc operations being completed.
      
      Similar state change is also needed for IEEE 802.11r FT protocol in
      the FT-over-DS case which does not use Authentication frame exchange
      in a transition to another BSS. For this to work with cfg80211, an
      authentication entry needs to be created for the target BSS without
      sending out an Authentication frame. The nl80211 authentication
      command can be used for this purpose, too, with the new attribute to
      indicate that the command is only for changing local state. This
      enables wpa_supplicant to complete FT-over-DS transition successfully.

      include cleanup: Update gfp.h and slab.h includes to prepare for breaking... · 5a0e3ad6
      Tejun Heo authored
      include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h
      
      percpu.h is included by sched.h and module.h and thus ends up being
      included when building most .c files.  percpu.h includes slab.h which
      in turn includes gfp.h making everything defined by the two files
      universally available and complicating inclusion dependencies.
      
      percpu.h -> slab.h dependency is about to be removed.  Prepare for
      this change by updating users of gfp and slab facilities include those
      headers directly instead of assuming availability.  As this conversion
      needs to touch large number of source files, the following script is
      used as the basis of conversion.
      
        http://userweb.kernel.org/~tj/misc/slabh-sweep.py
      
      
      
      The script does the followings.
      
      * Scan files for gfp and slab usages and update includes such that
        only the necessary includes are there.  ie. if only gfp is used,
        gfp.h, if slab is used, slab.h.
      
      * When the script inserts a new include, it looks at the include
        blocks and try to put the new include such that its order conforms
        to its surrounding.  It's put in the include block which contains
        core kernel includes, in the same order that the rest are ordered -
        alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
        doesn't seem to be any matching order.
      
      * If the script can't find a place to put a new include (mostly
        because the file doesn't have fitting include block), it prints out
        an error message indicating which .h file needs to be added to the
        file.
      
      The conversion was done in the following steps.
      
      1. The initial automatic conversion of all .c files updated slightly
         over 4000 files, deleting around 700 includes and adding ~480 gfp.h
         and ~3000 slab.h inclusions.  The script emitted errors for ~400
         files.
      
      2. Each error was manually checked.  Some didn't need the inclusion,
         some needed manual addition while adding it to implementation .h or
         embedding .c file was more appropriate for others.  This step added
         inclusions to around 150 files.
      
      3. The script was run again and the output was compared to the edits
         from #2 to make sure no file was left behind.
      
      4. Several build tests were done and a couple of problems were fixed.
         e.g. lib/decompress_*.c used malloc/free() wrappers around slab
         APIs requiring slab.h to be added manually.
      
      5. The script was run on all .h files but without automatically
         editing them as sprinkling gfp.h and slab.h inclusions around .h
         files could easily lead to inclusion dependency hell.  Most gfp.h
         inclusion directives were ignored as stuff from gfp.h was usually
         wildly available and often used in preprocessor macros.  Each
         slab.h inclusion directive was examined and added manually as
         necessary.
      
      6. percpu.h was updated not to include slab.h.
      
      7. Build test were done on the following configurations and failures
         were fixed.  CONFIG_GCOV_KERNEL was turned off for all tests (as my
         distributed build env didn't work with gcov compiles) and a few
         more options had to be turned off depending on archs to make things
         build (like ipr on powerpc/64 which failed due to missing writeq).
      
         * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
         * powerpc and powerpc64 SMP allmodconfig
         * sparc and sparc64 SMP allmodconfig
         * ia64 SMP allmodconfig
         * s390 SMP allmodconfig
         * alpha SMP allmodconfig
         * um on x86_64 SMP allmodconfig
      
      8. percpu.h modifications were reverted so that it could be applied as
         a separate patch and serve as bisection point.
      
      Given the fact that I had only a couple of failures from tests on step
      6, I'm fairly confident about the coverage of this conversion patch.
      If there is a breakage, it's likely to be something in one of the arch
      headers which should be easily discoverable easily on most builds of
      the specific arch.

      cfg80211: Add connection quality monitoring support to nl80211 · d6dc1a38
      Juuso Oikarinen authored
      
      
      Add support for basic configuration of a connection quality monitoring to the
      nl80211 interface, and basic support for notifying about triggered monitoring
      events.
      
      Via this interface a user-space connection manager may configure and receive
      pre-warning events of deteriorating WLAN connection quality, and start
      preparing for roaming in advance, before the connection is already lost.
      
      An example usage of such a trigger is starting scanning for nearby AP's in
      an attempt to find one with better connection quality, and associate to it
      before the connection characteristics of the existing connection become too bad
      or the association is even lost, leading in a prolonged delay in connectivity.
      
      The interface currently supports only RSSI, but it could be later extended
      to include other parameters, such as signal-to-noise ratio, if need for that
      arises.
