From 305a6cb8bc6aa464a7a5e2669d00ac4691f4a2a5 Mon Sep 17 00:00:00 2001 From: Jukka Rissanen Date: Fri, 4 May 2012 15:24:32 +0300 Subject: wifi: Allow max number of scan entries Do no limit the scan entries to 4 (G_SUPPLICANT_MAX_FAST_SCAN) but use the limit given by the driver. The limit is given by wpa_s. If the supplicant does not return the limit, then use 4 as a max value. --- gsupplicant/gsupplicant.h | 31 ++++++++++++++++++++++++------- 1 file changed, 24 insertions(+), 7 deletions(-) (limited to 'gsupplicant/gsupplicant.h') diff --git a/gsupplicant/gsupplicant.h b/gsupplicant/gsupplicant.h index 883de7f4..5dc53642 100644 --- a/gsupplicant/gsupplicant.h +++ b/gsupplicant/gsupplicant.h @@ -73,8 +73,6 @@ extern "C" { #define G_SUPPLICANT_PAIRWISE_TKIP (1 << 1) #define G_SUPPLICANT_PAIRWISE_CCMP (1 << 2) -#define G_SUPPLICANT_MAX_FAST_SCAN 4 - #define G_SUPPLICANT_WPS_CONFIGURED (1 << 0) #define G_SUPPLICANT_WPS_PBC (1 << 1) #define G_SUPPLICANT_WPS_PIN (1 << 2) @@ -139,15 +137,26 @@ struct _GSupplicantSSID { typedef struct _GSupplicantSSID GSupplicantSSID; +/* + * Max number of SSIDs that can be scanned. + * In wpa_s 0.7x the limit is 4. + * In wps_s 0.8 or later it is 16. + * The value is only used if wpa_supplicant does not return any max limit + * for number of scannable SSIDs. + */ +#define WPAS_MAX_SCAN_SSIDS 4 + +struct scan_ssid { + unsigned char ssid[32]; + uint8_t ssid_len; +}; + struct _GSupplicantScanParams { - struct scan_ssid { - unsigned char ssid[32]; - uint8_t ssid_len; - } ssids[G_SUPPLICANT_MAX_FAST_SCAN]; + GSList *ssids; uint8_t num_ssids; - uint16_t freqs[G_SUPPLICANT_MAX_FAST_SCAN]; + uint16_t *freqs; }; typedef struct _GSupplicantScanParams GSupplicantScanParams; @@ -250,6 +259,14 @@ typedef struct _GSupplicantCallbacks GSupplicantCallbacks; int g_supplicant_register(const GSupplicantCallbacks *callbacks); void g_supplicant_unregister(const GSupplicantCallbacks *callbacks); +static inline +void g_supplicant_free_scan_params(GSupplicantScanParams *scan_params) +{ + g_slist_free_full(scan_params->ssids, g_free); + g_free(scan_params->freqs); + g_free(scan_params); +} + #ifdef __cplusplus } #endif -- cgit v1.2.3
