      mac80211: Fix sparse warning for ssid_len on ieee80211_sta_config_auth() · 6cfe62cd
      Luis R. Rodriguez authored
      net/mac80211/mlme.c:2079:28: warning: symbol 'ssid_len' shadows an earlier one
      net/mac80211/mlme.c:2022:12: originally declared here
      ssid_len is already being declared and checked above so there is
      no need for it again.

      mac80211: tell driver when idle · 5cff20e6
      Johannes Berg authored
      When we aren't doing anything in mac80211, we can turn off
      much of the hardware, depending on the driver/hw. Not doing
      anything, aka being idle, means:
       * no monitor interfaces
       * no AP/mesh/wds interfaces
       * any station interfaces are in DISABLED state
       * any IBSS interfaces aren't trying to be in a network
       * we aren't trying to scan
      By creating a new function that verifies these conditions and calling
      it at strategic points where the states of those conditions change,
      we can easily make mac80211 tell the driver when we are idle to save
      Additionally, this fixes a small quirk where a recalculated powersave
      state is passed to the driver even if the hardware is about to stopped
      This patch intentionally doesn't touch radio_enabled because that is
      currently implemented to be a soft rfkill which is inappropriate here
      when we need to be able to wake up with low latency.
      One thing I'm not entirely sure about is this:
        phy0: device no longer idle - in use
        wlan0: direct probe to AP 00:11:24:91:07:4d try 1
        wlan0 direct probe responded
        wlan0: authenticate with AP 00:11:24:91:07:4d
        wlan0: authenticated
      > phy0: device now idle
      > phy0: device no longer idle - in use
        wlan0: associate with AP 00:11:24:91:07:4d
        wlan0: RX AssocResp from 00:11:24:91:07:4d (capab=0x401 status=0 aid=1)
        wlan0: associated
      Is it appropriate to go into idle state for a short time when we have
      just authenticated, but not associated yet? This happens only with the
      userspace SME, because we cannot really know how long it will wait
      before asking us to associate. Would going idle after a short timeout
      be more appropriate? We may need to revisit this, depending on what

      mac80211: fix probe response processing · 16cf438a
      Johannes Berg authored
      Due to the use of a _REQ_DIRECT_PROBE bit, which is
      unnecessary (and I wonder why it was done that way),
      an interesting situation can arise:
       1) we try to probe an access point
       2) the AP doesn't response in time
       3) we tell userspace that we gave up
       4) the AP suddenly responds
       5) we auth/assoc with the AP
      I've seen 4) happen in testing with hostapd SIGSTOPped,
      and when SIGCONTinued it processes the probe requests
      that came in and send responses. But 5) is not supposed
      to happen after we tell everybody we've given up on the
      To fix this, remove the _REQ_DIRECT_PROBE request bit,
      and process probe responses when we're in the relevant
      MLME state, namely IEEE80211_STA_MLME_DIRECT_PROBE.

      nl80211: Send timeout event on failed direct probe · e61f2340
      Jouni Malinen authored
      If the direct probe times out, we need to send the authentication
      timeout event to notify SME in the same way as we notify on timeout
      with authentication frames since the direct probe is run as part of
      the authentication attempt.

      mac80211: add driver ops wrappers · 24487981
      Johannes Berg authored
      In order to later add tracing or verifications to the driver
      calls mac80211 makes, this patch adds static inline wrappers
      for all operations.
      All calls are now written as
      	drv_<op>(local, ...);
      instead of
      	local->ops-><op>(&local->hw, ...);
      Where necessary, the wrappers also do existence checking and
      return default values as appropriate.

      mac80211: unify config_interface and bss_info_changed · 2d0ddec5
      Johannes Berg authored
      The config_interface method is a little strange, it contains the
      BSSID and beacon updates, while bss_info_changed contains most
      other BSS information for each interface. This patch removes
      config_interface and rolls all the information it previously
      passed to drivers into bss_info_changed.
