      cfg80211: pass name_assign_type to rdev_add_virtual_intf() · 6bab2e19
      Tom Gundersen authored
      This will expose in /sys whether the ifname of a device is set by
      userspace or generated by the kernel. The latter kind (wlanX, etc)
      is not deterministic, so userspace needs to rename these devices
      to names that are guaranteed to stay the same between reboots. The
      former, however should never be renamed, so userspace needs to be
      able to reliably tell the difference.
      
      Similar functionality was introduced for the rtnetlink core in
      commit 5517750f ("net: rtnetlink - make create_link take name_assign_type")

      cfg80211: add bss_type and privacy arguments in cfg80211_get_bss() · 6eb18137
      Dedy Lansky authored
      802.11ad adds new a network type (PBSS) and changes the capability
      field interpretation for the DMG (60G) band.
      The same 2 bits that were interpreted as "ESS" and "IBSS" before are
      re-used as a 2-bit field with 3 valid values (and 1 reserved). Valid
      values are: "IBSS", "PBSS" (new) and "AP".
      
      In order to get the BSS struct for the new PBSS networks, change the
      cfg80211_get_bss() function to take a new enum ieee80211_bss_type
      argument with the valid network types, as "capa_mask" and "capa_val"
      no longer work correctly (the search must be band-aware now.)
      
      The remaining bits in "capa_mask" and "capa_val" are used only for
      privacy matching so replace those two with a privacy enum as well.

      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 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.

      ath6kl: convert ar6004 hardware flags to firmware feature flags · eba95bce
      Kalle Valo authored
      The functionality defined through these flags were actually firmware features
      which can change between firmware versions. To make it possible to support
      different firmware versions with the same driver, convert the flags to firmware
      feature flags.
      
      For backwards compatibility support for old ar6004 firmware FW
      API 3 or smaller images we forcefully set the feature bits in the driver.
      Starting from FW API 5 the firmware image needs to set them.

      cfg80211: fix channel configuration in IBSS join · fe94f3a4
      Antonio Quartulli authored
      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).

      nl80211: fix scheduled scan RSSI matchset attribute confusion · ea73cbce
      Johannes Berg authored
      The scheduled scan matchsets were intended to be a list of filters,
      with the found BSS having to pass at least one of them to be passed
      to the host. When the RSSI attribute was added, however, this was
      broken and currently wpa_supplicant adds that attribute in its own
      matchset; however, it doesn't intend that to mean that anything
      that passes the RSSI filter should be passed to the host, instead
      it wants it to mean that everything needs to also have higher RSSI.
      
      This is semantically problematic because we have a list of filters
      like [ SSID1, SSID2, SSID3, RSSI ] with no real indication which
      one should be OR'ed and which one AND'ed.
      
      To fix this, move the RSSI filter attribute into each matchset. As
      we need to stay backward compatible, treat a matchset with only the
      RSSI attribute as a "default RSSI filter" for all other matchsets,
      but only if there are other matchsets (an RSSI-only matchset by
      itself is still desirable.)
      
      To make driver implementation easier, keep a global min_rssi_thold
      for the entire request as well. The only affected driver is ath6kl.
      
      I found this when I looked into the code after Raja Mani submitted
      a patch fixing the n_match_sets calculation to disregard the RSSI,
      but that patch didn't address the semantic issue.

      cfg80211: comprehensively check station changes · 77ee7c89
      Johannes Berg authored
      The station change API isn't being checked properly before
      drivers are called, and as a result it is difficult to see
      what should be allowed and what not.
      
      In order to comprehensively check the API parameters parse
      everything first, and then have the driver call a function
      (cfg80211_check_station_change()) with the additionally
      information about the kind of station that is being changed;
      this allows the function to make better decisions than the
      old code could.
      
      While at it, also add a few checks, particularly in mesh
      and clarify the TDLS station lifetime in documentation.
      
      To be able to reduce a few checks, ignore any flag set bits
      when the mask isn't set, they shouldn't be applied then.

      nl80211/cfg80211: support VHT channel configuration · 3d9d1d66
      Johannes Berg authored
      Change nl80211 to support specifying a VHT (or HT)
      using the control channel frequency (as before) and
      new attributes for the channel width and first and
      second center frequency. The old channel type is of
      course still supported for HT.
      
      Also change the cfg80211 channel definition struct
      to support these by adding the relevant fields to
      it (and removing the _type field.)
      
      This also adds new helper functions:
       - cfg80211_chandef_create to create a channel def
         struct given the control channel and channel type,
       - cfg80211_chandef_identical to check if two channel
         definitions are identical
       - cfg80211_chandef_compatible to check if the given
         channel definitions are compatible, and return the
         wider of the two
      
      This isn't entirely complete, but that doesn't matter
      until we have a driver using it. In particular, it's
      missing
       - regulatory checks on the usable bandwidth (if that
         even makes sense)
       - regulatory TX power (database can't deal with it)
       - a proper channel compatibility calculation for the
         new channel types

      cfg80211: pass a channel definition struct · 683b6d3b
      Johannes Berg authored
      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
      Johannes Berg authored
      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.

      The TX power setting is currently per wiphy (hardware

      is configured for the wiphy, the wdev will be NULL and
      the driver can still handle that, but when a wdev is
      given the TX power can be set only for that wdev now.
