From: Jouni Malinen Date: Tue, 30 Dec 2008 16:04:29 +0000 (+0200) Subject: Added ctrl_interface command for sending a SA Query request X-Git-Tag: hostap_0_6_7~45 X-Git-Url: http://www.project-moonshot.org/gitweb/?p=libeap.git;a=commitdiff_plain;h=88b4b4246d5d2a21f197359d7b5907a895bb3b14 Added ctrl_interface command for sending a SA Query request This can be useful for testing IEEE 802.11w functionality, so provide means for manual request to send a SA Query request. --- diff --git a/hostapd/ctrl_iface.c b/hostapd/ctrl_iface.c index f8b3a1d..7afd859 100644 --- a/hostapd/ctrl_iface.c +++ b/hostapd/ctrl_iface.c @@ -218,6 +218,26 @@ static int hostapd_ctrl_iface_new_sta(struct hostapd_data *hapd, } +#ifdef CONFIG_IEEE80211W +static int hostapd_ctrl_iface_sa_query(struct hostapd_data *hapd, + const char *txtaddr) +{ + u8 addr[ETH_ALEN];
