SCTP: Fix to encode PROTOCOL VIOLATION error cause correctly
PROTOCOL VIOLATION error cause in ABORT is bad encode when make abort chunk. When SCTP encode ABORT chunk with PROTOCOL VIOLATION error cause, it just add the error messages to PROTOCOL VIOLATION error cause, the rest four bytes(struct sctp_paramhdr) is just add to the chunk, not change the length of error cause. This cause the ABORT chunk to be a bad format. The chunk is like this: ABORT chunk Chunk type: ABORT (6) Chunk flags: 0x00 Chunk length: 72 (*1) Protocol violation cause Cause code: Protocol violation (0x000d) Cause length: 62 (*2) Cause information: 5468652063756D756C61746976652074736E2061636B2062... Cause padding: 0000 [Needless] 00030010 Chunk Length(*1) = 72 but Cause length(*2) only 62, not include the extend 4 bytes. ((72 - sizeof(chunk_hdr)) = 68) != (62 +3) / 4 * 4 Signed-off-by: Wei Yongjun <yjwei@cn.fujitsu.com> Signed-off-by: Vlad Yasevich <vladislav.yasevich@hp.com>
