Detailed Description

wpa_supplicant - Temporary BSSID blacklist

Function Documentation

int wpa_blacklist_add	(	struct wpa_supplicant *	wpa_s,
		const u8 *	bssid
	)

Add an BSSID to the blacklist.

Parameters

wpa_s	Pointer to wpa_supplicant data
bssid	BSSID to be added to the blacklist

Returns

Current blacklist count on success, -1 on failure

This function adds the specified BSSID to the blacklist or increases the blacklist count if the BSSID was already listed. It should be called when an association attempt fails either due to the selected BSS rejecting association or due to timeout.

This blacklist is used to force wpa_supplicant to go through all available BSSes before retrying to associate with an BSS that rejected or timed out association. It does not prevent the listed BSS from being used; it only changes the order in which they are tried.
