Subject: [PATCH 1/2] mac80211: save ssid info to ieee80211_bss_conf while assoc
Date: Mon,  7 Dec 2020 11:36:34 +0800	[thread overview]
Message-ID: <1607312195-3583-2-git-send-email-wgong@codeaurora.org> (raw)
In-Reply-To: <1607312195-3583-1-git-send-email-wgong@codeaurora.org>

The ssid info of ieee80211_bss_conf is filled in ieee80211_start_ap()
for AP mode. For STATION mode, it is empty, save the info from struct
ieee80211_mgd_assoc_data, the struct ieee80211_mgd_assoc_data will be
freed after assoc, so the ssid info of ieee80211_mgd_assoc_data can not
access after assoc, save ssid info to ieee80211_bss_conf, then ssid info
can be still access after assoc.
