[tracker] Task opened: Crash in websocket module

by sip-router

THIS IS AN AUTOMATED MESSAGE, DO NOT REPLY. A new Flyspray task has been opened. Details are below. User who did this - Vitaliy Aleksandrov (Vitaliy) Attached to Project - sip-router Summary - Crash in websocket module Task Type - Bug Report Category - Module Status - Unconfirmed Assigned To - Operating System - All Severity - Medium Priority - Normal Reported Version - 4.1 Due in Version - Undecided Due Date - Undecided Details - Latest kamailio 4.1 has a problem very similar to the one described in the FS#364. In very rare situation kamailio tries to make double free for wsc structure. core: <code> #0 0x00007f18704da425 in raise () from /lib/x86_64-linux-gnu/libc.so.6 #1 0x00007f18704ddb8b in abort () from /lib/x86_64-linux-gnu/libc.so.6 #2 0x0000000000557c02 in qm_free (qm=0x7f185e6ae000, p=0x7f185f04d700, file=0x7f1868a6a637 "websocket: ws_conn.c", func=0x7f1868a6aed9 "_wsconn_rm", line=140) at mem/q_malloc.c:470 #3 0x00007f1868a5b139 in _wsconn_rm (wsc=0x7f185f04d700) at ws_conn.c:140 #4 0x00007f1868a5c0e1 in wsconn_rm (wsc=0x7f185f04d700, run_event_route=WSCONN_EVENTROUTE_YES) at ws_conn.c:310 #5 0x00007f1868a5f264 in encode_and_send_ws_frame (frame=0x7ffffdf56160, conn_close=CONN_CLOSE_DONT) at ws_frame.c:303 #6 0x00007f1868a63336 in ws_frame_transmit (data=0x7ffffdf56230) at ws_frame.c:709 #7 0x000000000045933c in sr_event_exec (type=11, data=0x7ffffdf56230) at events.c:260 </code> logs: <code> kamailio[21357]: INFO: <script>: [HTTP] WebSocket connection closed [X.X.X.X:63514].

This is a very rare situation and it only happens in the next scenario: 0. User A (connected via websocket) established a conversation with user B (tcp/tls). TCP worker process 1 handles websocket connection to the A and tcp process 2 handles connection to the B. 1. User A sends BYE to B. Kamailio forwards BYE to B. 2.1. User A closes websocket connection before receiving 200 OK to the BYE request. 2.2. User B replies with 200 OK to the BYE. 3. Kamailio calls ws_frame_transmit() for "200 OK" and ws_frame_received() for "WS CLOSE" in different TCP workers. They both take wsc pointer by calling wscconn_get() and at the end to processes tries to call ws_conn_rm() for the same WSC connection which leads to double shm_free(). At now i'm trying to add reference counts to wsc in the same way they work in tcp_connection structure. Maybe somebody has a better idea how to fix this ?
