The put routine first decrements the users counter and then (if it is zero) locks the sta_bss_lock and removes one from the list and the hash. Thus, any of ieee80211_sta_config_auth, ieee80211_rx_bss_get or ieee80211_rx_mesh_bss_get can race with it by finding a bss that is about to get kfree-ed. Using atomic_dec_and_lock in ieee80211_rx_bss_put takes care of this race. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: John W. Linville <linville@tuxdriver.com> |
