      mac80211: allow drivers to control software crypto · fa7e1fbc
      Johannes Berg authored
      
      
      Some drivers unfortunately cannot support software crypto, but
      mac80211 currently assumes that they do.
      
      This has the issue that if the hardware enabling fails for some
      reason, the software fallback is used, which won't work. This
      clearly isn't desirable, the error should be reported and the
      key setting refused.
      
      Support this in mac80211 by allowing drivers to set a new HW
      flag IEEE80211_HW_SW_CRYPTO_CONTROL, in which case mac80211 will
      only allow software fallback if the set_key() method returns 1.
      The driver will also need to advertise supported cipher suites
      so that mac80211 doesn't advertise any (future) software ciphers
      that the driver can't actually do.
      
      While at it, to make it easier to support this, refactor the
      ieee80211_init_cipher_suites() code.

      mac80211: fix HW registration error paths · 54330bf6
      Johannes Berg authored
      
      
      Station info state is started in allocation, so should be
      destroyed on free (it's just a timer); rate control must
      be freed if anything afterwards fails to initialize.
      
      LED exit should be later, no need for locking there, but
      it needs to be done also when rate init failed.
      
      Also clean up the code by moving a label so the locking
      doesn't have to be done separately.

      mac80211: delete the assoc/auth timer upon suspend · c1e140bf
      Emmanuel Grumbach authored
      
      
      While suspending, we destroy the authentication /
      association that might be taking place. While doing so, we
      forgot to delete the timer which can be firing after
      local->suspended is already set, producing the warning below.
      
      Fix that by deleting the timer.

      Revert "wireless: Support of IFLA_INFO_KIND rtnl attribute" · 6e9f3fa4
      Johannes Berg authored
      This reverts commit ba1debdf
      
      .
      
      Oliver reported that it breaks network-manager, for some reason with
      this patch NM decides that the device isn't wireless but "generic"
      (ethernet), sees no carrier (as expected with wifi) and fails to do
      anything else with it.
      
      Revert this to unbreak userspace.

      cfg80211: change bandwidth reporting to explicit field · b51f3bee
      Johannes Berg authored
      
      
      For some reason, we made the bandwidth separate flags, which
      is rather confusing - a single rate cannot have different
      bandwidths at the same time.
      
      Change this to no longer be flags but use a separate field
      for the bandwidth ('bw') instead.
      
      While at it, add support for 5 and 10 MHz rates - these are
      reported as regular legacy rates with their real bitrate,
      but tagged as 5/10 now to make it easier to distinguish them.
      
      In the nl80211 API, the flags are preserved, but the code
      now can also clearly only set a single one of the flags.

      cfg80211: remove 80+80 MHz rate reporting · 97d910d0
      Johannes Berg authored
      
      
      These rates are treated the same as 160 MHz in the spec, so
      it makes no sense to distinguish them. As no driver uses them
      yet, this is also not a problem, just remove them.
      
      In the userspace API the field remains reserved to preserve
      API and ABI.

      mac80211: provide per-TID RX/TX MSDU counters · 79c892b8
      Johannes Berg authored
      
      
      Implement the new counters cfg80211 can now advertise to userspace.
      The TX code is in the sequence number handler, which is a bit odd,
      but that place already knows the TID and frame type, so it was
      easiest and least impact there.

      nl80211: support per-TID station statistics · 6de39808
      Johannes Berg authored
      
      
      The base for the current statistics is pretty mixed up, support
      exporting RX/TX statistics for MSDUs per TID. This (currently)
      covers received MSDUs, transmitted MSDUs and retries/failures
      thereof.
      
      Doing it per TID for MSDUs makes more sense than say only per AC
      because it's symmetric - we could export per-AC statistics for all
      frames (which AC we used for transmission can be determined also
      for management frames) but per TID is better and usually data
      frames are really the ones we care about. Also, on RX we can't
      determine the AC - but we do know the TID for any QoS MPDU we
      received.

      cfg80211: remove enum station_info_flags · 319090bf
      Johannes Berg authored
      
      
      This is really just duplicating the list of information that's
      already available in the nl80211 attribute, so remove the list.
      Two small changes are needed:
       * remove STATION_INFO_ASSOC_REQ_IES complete, but the length
         (assoc_req_ies_len) can be used instead
       * add NL80211_STA_INFO_RX_DROP_MISC which exists internally
         but not in nl80211 yet
      
      This gets rid of the duplicate maintenance of the two lists.
