To assign * values to multi-byte fields they _must_ be converted to * ieee byte order. To retrieve multi-byte values from incoming * frames, they must be converted to host order. * * - The len member of the frame structure does NOT!!! include * the MAC CRC. Therefore, the len field on rx'd frames should * have 4 subtracted from it. * * All functions declared here are implemented in p80211.c * * The types, macros, and functions defined here are primarily * used for encoding and decoding management frames. They are * designed to follow these patterns of use: * * DECODE: * 1) a frame of length len is received into buffer b * 2) using the hdr structure and macros, we determine the type * 3) an appropriate mgmt frame structure, mf, is allocated and zeroed * 4) mf.hdr = b * mf.buf = b * mf.len = len * 5) call mgmt_decode( mf ) * 6) the frame field pointers in mf are now set. Note that any * multi-byte frame field values accessed using the frame field * pointers are in ieee byte order and will have to be converted * to host order. * * ENCODE: * 1) Library client allocates buffer space for maximum length * frame of the desired type * 2) Library client allocates a mgmt frame structure, called mf, * of the desired type * 3) Set the following: * mf.type = <desired type> * mf.buf = <allocated buffer address> * 4) call mgmt_encode( mf ) * 5) all of the fixed field pointers and fixed length information element * pointers in mf are now set to their respective locations in the * allocated space (fortunately, all variable length information elements * fall at the end of their respective frames). * 5a) The length field is set to include the last of the fixed and fixed * length fields. It may have to be updated for optional or variable * length information elements. * 6) Optional and variable length information elements are special cases * and must be handled individually by the client code. * -------------------------------------------------------------------- */ #ifndef _P80211MGMT_H #define _P80211MGMT_H #ifndef _P80211HDR_H #include "p80211hdr.h" #endif /*-- Information Element IDs --------------------*/ #define WLAN_EID_SSID 0 #define WLAN_EID_SUPP_RATES 1 #define WLAN_EID_FH_PARMS 2 #define WLAN_EID_DS_PARMS 3 #define WLAN_EID_CF_PARMS 4 #define WLAN_EID_TIM 5 #define WLAN_EID_IBSS_PARMS 6 /*-- values 7-15 reserved --*/ #define WLAN_EID_CHALLENGE 16 /*-- values 17-31 reserved for challenge text extension --*/ /*-- values 32-255 reserved --*/ /*-- Reason Codes -------------------------------*/ #define WLAN_MGMT_REASON_RSVD 0 #define WLAN_MGMT_REASON_UNSPEC 1 #define WLAN_MGMT_REASON_PRIOR_AUTH_INVALID 2 #define WLAN_MGMT_REASON_DEAUTH_LEAVING 3 #define WLAN_MGMT_REASON_DISASSOC_INACTIVE 4 #define WLAN_MGMT_REASON_DISASSOC_AP_BUSY 5 #define WLAN_MGMT_REASON_CLASS2_NONAUTH 6 #define WLAN_MGMT_REASON_CLASS3_NONASSOC 7 #define WLAN_MGMT_REASON_DISASSOC_STA_HASLEFT 8 #define WLAN_MGMT_REASON_CANT_ASSOC_NONAUTH 9 /*-- Status Codes -------------------------------*/ #define WLAN_MGMT_STATUS_SUCCESS 0 #define WLAN_MGMT_STATUS_UNSPEC_FAILURE 1 #define WLAN_MGMT_STATUS_CAPS_UNSUPPORTED 10 #define WLAN_MGMT_STATUS_REASSOC_NO_ASSOC 11 #define WLAN_MGMT_STATUS_ASSOC_DENIED_UNSPEC 12 #define WLAN_MGMT_STATUS_UNSUPPORTED_AUTHALG 13 #define WLAN_MGMT_STATUS_RX_AUTH_NOSEQ 14 #define WLAN_MGMT_STATUS_CHALLENGE_FAIL 15 #define WLAN_MGMT_STATUS_AUTH_TIMEOUT 16 #define WLAN_MGMT_STATUS_ASSOC_DENIED_BUSY 17 #define WLAN_MGMT_STATUS_ASSOC_DENIED_RATES 18 /* p80211b additions */ #define WLAN_MGMT_STATUS_ASSOC_DENIED_NOSHORT 19 #define WLAN_MGMT_STATUS_ASSOC_DENIED_NOPBCC 20 #define WLAN_MGMT_STATUS_ASSOC_DENIED_NOAGILITY 21 /*-- Auth Algorithm Field ---------------------------*/ #define WLAN_AUTH_ALG_OPENSYSTEM 0 #define WLAN_AUTH_ALG_SHAREDKEY 1 /*-- Management Frame Field Offsets -------------*/ /* Note: Not all fields are listed because of variable lengths, */ /* see the code in p80211.c to see how we search for fields */ /* Note: These offsets are from the start of the frame data */ #define WLAN_BEACON_OFF_TS 0 #define WLAN_BEACON_OFF_BCN_int 8 #define WLAN_BEACON_OFF_CAPINFO 10 #define WLAN_BEACON_OFF_SSID 12 #define WLAN_DISASSOC_OFF_REASON 0 #define WLAN_ASSOCREQ_OFF_CAP_INFO 0 #define WLAN_ASSOCREQ_OFF_LISTEN_int 2 #define WLAN_ASSOCREQ_OFF_SSID 4 #define WLAN_ASSOCRESP_OFF_CAP_INFO 0 #define WLAN_ASSOCRESP_OFF_STATUS 2 #define WLAN_ASSOCRESP_OFF_AID 4 #define WLAN_ASSOCRESP_OFF_SUPP_RATES 6 #define WLAN_REASSOCREQ_OFF_CAP_INFO 0 #define WLAN_REASSOCREQ_OFF_LISTEN_int 2 #define WLAN_REASSOCREQ_OFF_CURR_AP 4 #define WLAN_REASSOCREQ_OFF_SSID 10 #define WLAN_REASSOCRESP_OFF_CAP_INFO 0 #define WLAN_REASSOCRESP_OFF_STATUS 2 #define WLAN_REASSOCRESP_OFF_AID 4 #define WLAN_REASSOCRESP_OFF_SUPP_RATES 6 #define WLAN_PROBEREQ_OFF_SSID 0 #define WLAN_PROBERESP_OFF_TS 0 #define WLAN_PROBERESP_OFF_BCN_int 8 #define WLAN_PROBERESP_OFF_CAP_INFO 10 #define WLAN_PROBERESP_OFF_SSID 12 #define WLAN_AUTHEN_OFF_AUTH_ALG 0 #define WLAN_AUTHEN_OFF_AUTH_SEQ 2 #define WLAN_AUTHEN_OFF_STATUS 4 #define WLAN_AUTHEN_OFF_CHALLENGE 6 #define WLAN_DEAUTHEN_OFF_REASON 0 /*-- Capability Field ---------------------------*/ #define WLAN_GET_MGMT_CAP_INFO_ESS(n) ((n) & BIT(0)) #define WLAN_GET_MGMT_CAP_INFO_IBSS(n) (((n) & BIT(1)) >> 1) #define WLAN_GET_MGMT_CAP_INFO_CFPOLLABLE(n) (((n) & BIT(2)) >> 2) #define WLAN_GET_MGMT_CAP_INFO_CFPOLLREQ(n) (((n) & BIT(3)) >> 3) #define WLAN_GET_MGMT_CAP_INFO_PRIVACY(n) (((n) & BIT(4)) >> 4) /* p80211b additions */ #define WLAN_GET_MGMT_CAP_INFO_SHORT(n) (((n) & BIT(5)) >> 5) #define WLAN_GET_MGMT_CAP_INFO_PBCC(n) (((n) & BIT(6)) >> 6) #define WLAN_GET_MGMT_CAP_INFO_AGILITY(n) (((n) & BIT(7)) >> 7) #define WLAN_SET_MGMT_CAP_INFO_ESS(n) (n) #define WLAN_SET_MGMT_CAP_INFO_IBSS(n) ((n) << 1) #define WLAN_SET_MGMT_CAP_INFO_CFPOLLABLE(n) ((n) << 2) #define WLAN_SET_MGMT_CAP_INFO_CFPOLLREQ(n) ((n) << 3) #define WLAN_SET_MGMT_CAP_INFO_PRIVACY(n) ((n) << 4) /* p80211b additions */ #define WLAN_SET_MGMT_CAP_INFO_SHORT(n) ((n) << 5) #define WLAN_SET_MGMT_CAP_INFO_PBCC(n) ((n) << 6) #define WLAN_SET_MGMT_CAP_INFO_AGILITY(n) ((n) << 7) /*-- Information Element Types --------------------*/ /* prototype structure, all IEs start with these members */ struct wlan_ie { u8 eid;
