From a987f762cafb25c0fedf88f15e328edd897210ed Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Tue, 7 Apr 2009 15:44:29 +0800 Subject: sctp: fix report unrecognized parameter in ACSONF-ACK RFC5061 Section 5.2. Upon Reception of an ASCONF Chunk V2) In processing the chunk, the receiver should build a response message with the appropriate error TLVs, as specified in the Parameter type bits, for any ASCONF Parameter it does not understand. To indicate an unrecognized parameter, Cause Type 8 should be used as defined in the ERROR in Section 3.3.10.8, [RFC4960]. The endpoint may also use the response to carry rejections for other reasons, such as resource shortages, etc., using the Error Cause TLV and an appropriate error condition. So we should indicate an unrecognized parameter with error SCTP_ERROR_UNKNOWN_PARAM in ACSONF-ACK chunk, not SCTP_ERROR_INV_PARAM.
