From: =?UTF-8?q?Rafa=C5=82=20Mi=C5=82ecki?= Date: Mon, 11 Jan 2016 19:18:06 +0100 Subject: [PATCH] nl80211: Report disassociated STA / lost peer for the correct BSS MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit We shouldn't use drv->ctx as it always points to the first BSS. When using FullMAC driver with multi-BSS support it resulted in incorrect treating nl80211 events. I noticed with with brcmfmac and BCM43602. Before my change I was getting "disassociated" on a wrong interface: wlan0-1: STA 78:d6:f0:00:11:22 IEEE 802.11: associated wlan0-1: STA 78:d6:f0:00:11:22 WPA: pairwise key handshake completed (RSN) wlan0: STA 78:d6:f0:00:11:22 IEEE 802.11: disassociated With this patch it works as expected: wlan0-1: STA 78:d6:f0:00:11:22 IEEE 802.11: associated wlan0-1: STA 78:d6:f0:00:11:22 WPA: pairwise key handshake completed (RSN) wlan0-1: STA 78:d6:f0:00:11:22 IEEE 802.11: disassociated This doesn't apply to hostapd dealing with SoftMAC drivers when handling AP SME & MLME is done it hostapd not the firmware.
