/* Mesh Control field helper functions
 *
 * Per IEEE 802.11s Draft 12.0 section 7.2.2.1:
 *
 * The frame body consists of either:
 * The MSDU (or a fragment thereof), the Mesh Control field (if and only if the
 * frame is transmitted by a mesh STA and the Mesh Control Present subfield of
 * the QoS Control field is 1)...
 *
 * 8.2.4.5.1 "QoS Control field structure", table 8-4, in 802.11-2012,
 * seems to indicate that the bit that means "Mesh Control Present" in
 * frames sent by mesh STAs in a mesh BSS is part of the TXOP Limit field,
 * the AP PS Buffer State field, the TXOP Duration Requested field, or the
 * Queue Size field in some data frames in non-mesh BSSes.
 *
 * We need a statefull sniffer for that.  For now, use heuristics.
 *
 * Notably, only mesh data frames contain the Mesh Control field in the header.
 * Other frames that contain mesh control (i.e., multihop action frames) have
 * it deeper in the frame body where it can be definitively identified.
 * Further, mesh data frames always have to-ds and from-ds either 11 or 01.  We
 * use these facts to make our heuristics more reliable.

         and just stick the payload into an 802.11 frame.  I've seen
         captures that show frames of that sort.

         We also handle some odd form of encapsulation in which a
         complete Ethernet frame is encapsulated within an 802.11
         data frame, with no 802.2 header.  This has been seen
         from some hardware.

         On top of that, at least at some point it appeared that
         the OLPC XO sent out frames with two bytes of 0 between
         the "end" of the 802.11 header and the beginning of
         the payload.

         So, if the packet doesn't start with 0xaa 0xaa:

           we first use the same scheme that linux-wlan-ng does to detect
           those encapsulated Ethernet frames, namely looking to see whether
           the frame either starts with 6 octets that match the destination
           address from the 802.11 header or has 6 octets that match the
           source address from the 802.11 header following the first 6 octets,
           and, if so, treat it as an encapsulated Ethernet frame;

           otherwise, we use the same scheme that we use in the Ethernet
           dissector to recognize Netware 802.3 frames, namely checking
           whether the packet starts with 0xff 0xff and, if so, treat it
           as an encapsulated IPX frame, and then check whether the
           packet starts with 0x00 0x00 and, if so, treat it as an OLPC

/*
 * 8.2.4.1.10 "Order field" says:
 *
 *  The Order field is 1 bit in length. It is used for two purposes:
 *
 *    -- It is set to 1 in a non-QoS data frame transmitted by a non-QoS
 *       STA to indicate that the frame contains an MSDU, or fragment
 *       thereof, that is being transferred using the StrictlyOrdered
 *       service class.
 *
 *    -- It is set to 1 in a QoS data or management frame transmitted
 *       with a value of HT_GF or HT_MF for the FORMAT parameter of the
 *       TXVECTOR to indicate that the frame contains an HT Control field.
 *
 * 802.11ac changes the second of those clauses to say "HT_GF, HT_MF,
 * or VHT", indicates that bit B0 of the field is 0 for HT and 1 for
 * VHT (stealing a reserved bit from the Link Adaptation Control field),
 * and that everything except for "AC Constraint" and "RDG/More Cowbell^W
 * PPDU" is different for the VHT version.
 *
 *  802.11ax changes the meaning of the first two bits:
 *
 *     B0 = 0         means High Throughput
 *     B0 = 1, B1 = 0 means Very High Throughput
 *     B0 = 1, B1 = 1 means High Efficiency
 *
 * I read the second clause of 8.2.4.1.10 "Order field", as modified by
 * 802.11ac, as meaning that, for QoS data and management frames, the
 * Order field will *only* be set to 1 for HT or VHT frames, and therefore
 * that we do *not* have to determine, from radio metadata, whether the
 * frame was transmitted as an HT or VHT frame.
 *
 * (See bug 11351, in which a frame with an HT Control field, with a
 * radiotap header, lacks the MCS or VHT fields in the radiotap header,
 * so Wireshark has no clue that it's an HT or VHT field, and misdissected
 * the packet.  Omnipeek, which also appeared to have no clue that it was
 * an HT or VHT field - it called it an 802.11b frame - *did* dissect the
 * HT Control field.)
 *
 * 802.11ax changes the reserved bit to differentiate between the HE version
 * and the VHT version, and adds different types of Aggregate Control info.

  /*
   * XXX - the 802.11 specs aren't particularly clear on how the SSID
   * is to be interpreted.
   *
   * IEEE Std 802.11-1999, section 7.3.2.2 "Service Set Identity (SSID)
   * element" says just
   *
   *    The length of the SSID information field is between 0 and 32
   *    octets. A 0 length information field indicates the broadcast SSID.
   *
   * with no indication that those octets encode a string.
   *
   * IEEE Std 802.11-2012, section 8.4.2.2 "SSID element", says that *but*
   * says after it
   *
   *    When the UTF-8 SSID subfield of the Extended Capabilities element
   *    is equal to 1 in the frame that includes the SSID element, the
   *    SSID is interpreted using UTF-8 encoding.
   *
   *    NOTE -- This is true for Beacon and Probe Response frames when the
   *    MLME-START.request primitive was issued with the SSIDEncoding
   *    parameter equal to UTF-8.
   *
   * and the SSIDEncoding parameter can either be UNSPECIFIED or UTF-8.
   *
   * So I *guess* that means that, if the UTF-8 SSID subfield isn't
   * equal to 1, the SSID is, in theory, just a bunch of octets, but
   * in practice, *probably* ASCII as that's the typical convention,
   * and, if it is equal to 1, it's a UTF-8 string.  (Of course, a
   * host can put anything there it wants to, so we shouldn't just
   * assume that it's *valid* ASCII or *valid* UTF-8.)
   *
   * So we really should extract it as an array of ssid_len bytes,
   * pass those bytes to Dot11DecryptSetLastSSID(), and:
   *
   *    If the UTF-8 SSID subfield isn't set to 1, put the SSID in
   *    as an ENC_ASCII string;
   *
   *    If the UTF-8 SSID subfield is set to 1, put it in as an
   *    ENC_UTF_8 string;
   *
   * and rely on the libwireshark core code to somehow deal with
   * non-ASCII characters or invalid UTF-8 sequences or valid-but-
   * not-all-printable ASCII or UTF-8 strings in the protocol tree
   * display.  I'm not sure we can currently rely on it to handle
   * invalid UTF-8 or non-printable characters in UTF-8 strings,
   * however, so we just treat it as ASCII for now.
   *
   * We also need a better way of getting the display format of a
   * string value, so we can do something other than run it through
   * format_text(), which won't handle UTF-8.
   *
   * Addendum: 802.11 2012 points out that a Zero-length SSID means
   * the Wildcard SSID. Make it so. From 8.4.2.2 of 802.11 2012:
   *
   * "The length of the SSID field is between 0 and 32 octets. A SSID
   *  field of length 0 is used within Probe Request management frames to
   *  indicate the wildcard SSID. The wildcard SSID is also used in
   *  Beacon and Probe Response frames transmitted by mesh STAs."
   *
   * Also, we have to return a non-zero value here to prevent an ugly
   * undissected field warning. Since this code is only called from
   * one place and is used in call to dissector_try_uint_new, it is
   * OK to do so.

         and just stick the payload into an 802.11 frame.  I've seen
         captures that show frames of that sort.

         We also handle some odd form of encapsulation in which a
         complete Ethernet frame is encapsulated within an 802.11
         data frame, with no 802.2 header.  This has been seen
         from some hardware.

         On top of that, at least at some point it appeared that
         the OLPC XO sent out frames with two bytes of 0 between
         the "end" of the 802.11 header and the beginning of
         the payload. Something similar has also been observed
         with Atheros chipsets. There the sequence control field
         seems repeated.

         So, if the packet doesn't start with 0xaa 0xaa:

           we first use the same scheme that linux-wlan-ng does to detect
           those encapsulated Ethernet frames, namely looking to see whether
           the frame either starts with 6 octets that match the destination
           address from the 802.11 header or has 6 octets that match the
           source address from the 802.11 header following the first 6 octets,
           and, if so, treat it as an encapsulated Ethernet frame;

           otherwise, we use the same scheme that we use in the Ethernet
           dissector to recognize Netware 802.3 frames, namely checking
           whether the packet starts with 0xff 0xff and, if so, treat it
           as an encapsulated IPX frame, and then check whether the
           packet starts with 0x00 0x00 and, if so, treat it as an OLPC
           frame, or check the packet starts with the repetition of the
           sequence control field and, if so, treat it as an Atheros frame. */
