      mwifiex: Track BA sequence number reset · 8acbea61
      由 Paul Stewart 提交于 
      Some stations reset the sequence number for traffic-ids (TIDs)
as they initiate a block-ACK session.  In order to detect such
behavior, mwifiex must note the starting sequence number given
during the ADDBA request.  If the first received sequence number
after the ADDBA falls outside the receive window for this TID but
after the the ADDBA starting sequence number, we can assume that
this AP has reset its sequence number during the ADDBA.  In this
case we must adjust the input window backward to incorporate this
received sequence number instead of ignoring it.  Otherwise, we
could fail to successfully retrieve an arbitrarily large number
of downstream frames at the beginning of the block-ACK session.

      cfg80211: Pass TDLS peer capability information in tdls_mgmt · df942e7b
      由 Sunil Dutt Undekari 提交于 
      While framing the TDLS Setup Confirmation frame, the driver needs to
know if the TDLS peer is VHT/HT/WMM capable and thus shall construct
the VHT/HT operation / WMM parameter elements accordingly. Supplicant
determines if the TDLS peer is VHT/HT/WMM capable based on the
presence of the respective IEs in the received TDLS Setup Response frame.

The host driver should not need to parse the received TDLS Response
frame and thus, should be able to rely on the supplicant to indicate
the capability of the peer through additional flags while transmitting
the TDLS Setup Confirmation frame through tdls_mgmt operations.

      cfg80211: fix channel configuration in IBSS join · fe94f3a4
      由 Antonio Quartulli 提交于 
      When receiving an IBSS_JOINED event select the BSS object
based on the {bssid, channel} couple rather than the bssid
only.
With the current approach if another cell having the same
BSSID (but using a different channel) exists then cfg80211
picks up the wrong BSS object.
The result is a mismatching channel configuration between
cfg80211 and the driver, that can lead to any sort of
problem.

The issue can be triggered by having an IBSS sitting on
given channel and then asking the driver to create a new
cell using the same BSSID but with a different frequency.
By passing the channel to cfg80211_get_bss() we can solve
this ambiguity and retrieve/create the correct BSS object.
All the users of cfg80211_ibss_joined() have been changed
accordingly.

Moreover WARN when cfg80211_ibss_joined() gets a NULL
channel as argument and remove a bogus call of the same
function in ath6kl (it does not make sense to call
cfg80211_ibss_joined() with a zero BSSID on ibss-leave).

      cfg80211: make connect ie param const · 4b5800fe
      由 Johannes Berg 提交于 
      This required liberally sprinkling 'const' over brcmfmac
and mwifiex but seems like a useful thing to do since the
pointer can't really be written.

      Addition of the frequency hints showed up couple of places in cfg80211
where pointers could be marked const and a shared function could be used
to fetch a valid channel.
