This is followed by the struct wpa_driver_ops that each 11 * driver wrapper will beed to define with callback functions for requesting 12 * driver operations. After this, there are definitions for driver event 13 * reporting with wpa_supplicant_event() and some convenience helper functions 14 * that can be used to report events. 15 */ 16 17#ifndef DRIVER_H 18#define DRIVER_H 19 20#define WPA_SUPPLICANT_DRIVER_VERSION 4 21 22#include "common/defs.h" 23#include "utils/list.h" 24 25#define HOSTAPD_CHAN_DISABLED 0x00000001 26#define HOSTAPD_CHAN_PASSIVE_SCAN 0x00000002 27#define HOSTAPD_CHAN_NO_IBSS 0x00000004 28#define HOSTAPD_CHAN_RADAR 0x00000008 29#define HOSTAPD_CHAN_HT40PLUS 0x00000010 30#define HOSTAPD_CHAN_HT40MINUS 0x00000020 31#define HOSTAPD_CHAN_HT40 0x00000040 32#define HOSTAPD_CHAN_SURVEY_LIST_INITIALIZED 0x00000080 33 34#define HOSTAPD_CHAN_DFS_UNKNOWN 0x00000000 35#define HOSTAPD_CHAN_DFS_USABLE 0x00000100 36#define HOSTAPD_CHAN_DFS_UNAVAILABLE 0x00000200 37#define HOSTAPD_CHAN_DFS_AVAILABLE 0x00000300 38#define HOSTAPD_CHAN_DFS_MASK 0x00000300 39 40#define HOSTAPD_CHAN_VHT_10_70 0x00000800 41#define HOSTAPD_CHAN_VHT_30_50 0x00001000 42#define HOSTAPD_CHAN_VHT_50_30 0x00002000 43#define HOSTAPD_CHAN_VHT_70_10 0x00004000 44 45enum reg_change_initiator { 46 REGDOM_SET_BY_CORE, 47 REGDOM_SET_BY_USER, 48 REGDOM_SET_BY_DRIVER, 49 REGDOM_SET_BY_COUNTRY_IE, 50}; 51 52/** 53 * struct hostapd_channel_data - Channel information 54 */ 55struct hostapd_channel_data { 56 /** 57 * chan - Channel number (IEEE 802.11) 58 */ 59 short chan; 60 61 /** 62 * freq - Frequency in MHz 63 */ 64 int freq; 65 66 /** 67 * flag - Channel flags (HOSTAPD_CHAN_*) 68 */ 69 int flag; 70 71 /** 72 * max_tx_power - Regulatory transmit power limit in dBm 73 */ 74 u8 max_tx_power; 75 76 /* 77 * survey_list - Linked list of surveys 78 */ 79 struct dl_list survey_list; 80 81 /** 82 * min_nf - Minimum observed noise floor, in dBm, based on all 83 * surveyed channel data 84 */ 85 s8 min_nf; 86 87#ifdef CONFIG_ACS 88 /** 89 * interference_factor - Computed interference factor on this 90 * channel (used internally in src/ap/acs.c; driver wrappers do not 91 * need to set this) 92 */ 93 long double interference_factor; 94#endif /* CONFIG_ACS */ 95}; 96 97#define HOSTAPD_MODE_FLAG_HT_INFO_KNOWN BIT(0) 98#define HOSTAPD_MODE_FLAG_VHT_INFO_KNOWN BIT(1) 99 100/** 101 * struct hostapd_hw_modes - Supported hardware mode information 102 */ 103struct hostapd_hw_modes { 104 /** 105 * mode - Hardware mode 106 */ 107 enum hostapd_hw_mode mode; 108 109 /** 110 * num_channels - Number of entries in the channels array 111 */ 112 int num_channels; 113 114 /** 115 * channels - Array of supported channels 116 */ 117 struct hostapd_channel_data *channels; 118 119 /** 120 * num_rates - Number of entries in the rates array 121 */ 122 int num_rates; 123 124 /** 125 * rates - Array of supported rates in 100 kbps units 126 */ 127 int *rates; 128 129 /** 130 * ht_capab - HT (IEEE 802.11n) capabilities 131 */ 132 u16 ht_capab; 133 134 /** 135 * mcs_set - MCS (IEEE 802.11n) rate parameters 136 */ 137 u8 mcs_set[16]; 138 139 /** 140 * a_mpdu_params - A-MPDU (IEEE 802.11n) parameters 141 */ 142 u8 a_mpdu_params; 143 144 /** 145 * vht_capab - VHT (IEEE 802.11ac) capabilities 146 */ 147 u32 vht_capab; 148 149 /** 150 * vht_mcs_set - VHT MCS (IEEE 802.11ac) rate parameters 151 */ 152 u8 vht_mcs_set[8]; 153 154 unsigned int flags; /* HOSTAPD_MODE_FLAG_* */ 155}; 156 157 158#define IEEE80211_MODE_INFRA 0 159#define IEEE80211_MODE_IBSS 1 160#define IEEE80211_MODE_AP 2 161 162#define IEEE80211_CAP_ESS 0x0001 163#define IEEE80211_CAP_IBSS 0x0002 164#define IEEE80211_CAP_PRIVACY 0x0010 165 166/* DMG (60 GHz) IEEE 802.11ad */ 167/* type - bits 0..1 */ 168#define IEEE80211_CAP_DMG_MASK 0x0003 169#define IEEE80211_CAP_DMG_IBSS 0x0001 /* Tx by: STA */ 170#define IEEE80211_CAP_DMG_PBSS 0x0002 /* Tx by: PCP */ 171#define IEEE80211_CAP_DMG_AP 0x0003 /* Tx by: AP */ 172 173#define WPA_SCAN_QUAL_INVALID BIT(0) 174#define WPA_SCAN_NOISE_INVALID BIT(1) 175#define WPA_SCAN_LEVEL_INVALID BIT(2) 176#define WPA_SCAN_LEVEL_DBM BIT(3) 177#define WPA_SCAN_AUTHENTICATED BIT(4) 178#define WPA_SCAN_ASSOCIATED BIT(5) 179 180/** 181 * struct wpa_scan_res - Scan result for an BSS/IBSS 182 * @flags: information flags about the BSS/IBSS (WPA_SCAN_*) 183 * @bssid: BSSID 184 * @freq: frequency of the channel in MHz (e.g., 2412 = channel 1) 185 * @beacon_int: beacon interval in TUs (host byte order) 186 * @caps: capability information field in host byte order 187 * @qual: signal quality 188 * @noise: noise level 189 * @level: signal level 190 * @tsf: Timestamp 191 * @age: Age of the information in milliseconds (i.e., how many milliseconds 192 * ago the last Beacon or Probe Response frame was received) 193 * @ie_len: length of the following IE field in octets 194 * @beacon_ie_len: length of the following Beacon IE field in octets 195 * 196 * This structure is used as a generic format for scan results from the 197 * driver.
