Subject: [PATCH] rfcomm/core.c avoid dangling pointer, check session
rfcomm_process_sessions is calling rfcomm_process_rx, but
in this case the session is closed and freed leaving a
dangling pointer that blows up when rfcomm_process_rx returns
and rfcomm_process_dlcs is called with the now dangling session
pointer.
I can reproduce using blueman-manager on desktop, and Motorola S305 bluetooth
headset. Start out with the desktop as the last device the S305 paired
with.
desktop, connect to the S305,
S305, turn on
desktop (connection fails)
desktop (connection automatically comes up now that S305 is on)
desktop disconnect S305
desktop (kernel panic)
While rfcomm_process_sessions looks symmetrical,
rfcomm_session_hold(s);
rfcomm_process_rx
rfcomm_process_dlcs
rfcomm_session_put(s);
rfcomm_process_rx
if (sk->sk_state == BT_CLOSED) {
if (!s->initiator)
rfcomm_session_put(s);
rfcomm_session_close(s, sk->sk_err);
Which isn't symmetrical.
