Harald Welte f0206b949b Catch exceptions while decoding the packet ... If any exceptions are found while decoding the packet, remove it from the output trace to ensure no information leaks. In my real-world traces, I e.g. got the following exception terminating the program: CHOICE._from_per: S1AP-PDU, unknown extension index 699866529169900427952657872967740904512772918212192949539462653507496501180206847298869570851487786014667431700603926958879953036143148400114887836583469249625472224706264417515341607478659710751184333540332091231808038155414952989252906034887075176400074366401692584783210687966823902077240699797242085375 Traceback (most recent call last): File "./s1ap_reiniger.py", line 245, in <module> handle_pcap(sys.argv[1], sys.argv[2]) File "./s1ap_reiniger.py", line 215, in handle_pcap pkt = handle_sctp_pkt(pkt, i) File "./s1ap_reiniger.py", line 193, in handle_sctp_pkt success = handle_sctp_chunk(chunk, pkt_number) File "./s1ap_reiniger.py", line 167, in handle_sctp_chunk handle_s1ap(s1ap(), pkt_number) File "./s1ap_reiniger.py", line 122, in handle_s1ap log.info("Processing S1AP message '%s:%s' (Packet %d)" % (msg[0], msg[1]['value'][0], pkt_number)) TypeError: byte indices must be integers or slices, not str		2019-09-27 10:04:54 +02:00
