-Subject: [PATCH 1/1] tty: n_hdlc: get rid of racy n_hdlc.tbuf
-
-Currently N_HDLC line discipline uses a self-made singly linked list for
-data buffers and has n_hdlc.tbuf pointer for buffer retransmitting after
-an error.
-
-The commit be10eb7589337e5defbe214dae038a53dd21add8
-("tty: n_hdlc add buffer flushing") introduced racy access to n_hdlc.tbuf.
-After tx error concurrent flush_tx_queue() and n_hdlc_send_frames() can put
-one data buffer to tx_free_buf_list twice. That causes double free in
-n_hdlc_release().
-
-Let's use standard kernel linked list and get rid of n_hdlc.tbuf:
-in case of tx error put current data buffer after the head of tx_buf_list.
-
