Extend the SCTP decoder to parse chunk headers after the 12-byte common header. Each chunk is validated for minimum header size and length consistency per RFC 4960 sec 3.2. Add SCTPChunkHdr and SCTPVars structs to track per-packet chunk metadata Add five new decoder events for protocol violations: - SCTP_CHUNK_TOO_SMALL: insufficient data for a chunk header - SCTP_CHUNK_LEN_INVALID: chunk length < 4 or exceeds packet - SCTP_INIT_CHUNK_NOT_ALONE: INIT/INIT_ACK bundled (RFC 4960 sec 6.10) - SCTP_INIT_WITH_NON_ZERO_VTAG: INIT with vtag != 0 (RFC 4960 sec 8.5.1) - SCTP_DATA_WITH_ZERO_VTAG: DATA chunk with vtag == 0 Ticket #4251 |
