Hello,
Patches 1-2 fix the memory leaks that syzbot has reported in net/llc:
memory leak in llc_ui_create (2)
memory leak in llc_ui_sendmsg
memory leak in llc_conn_ac_send_sabme_cmd_p_set_x
Patches 3-4 fix related bugs that I noticed while reading this code.
Note: I've tested that this fixes the syzbot bugs, but otherwise I don't
know of any way to test this code.
Eric Biggers (4):
llc: fix sk_buff leak in llc_sap_state_process()
llc: fix sk_buff leak in llc_conn_service()
llc: fix another potential sk_buff leak in llc_ui_sendmsg()
llc: fix sk_buff refcounting in llc_conn_state_process()
