I am trying to implement support for DTLS over SCTP; for this purpose I need to use SCTP AUTH protection.
I have read the RFC 6458 (SCTP Sockets API) and started implementation based on this, but when I tried to compile my code I discovered that lksctp implementation does not support the final API described in RFC 6458, but an old draft-ietf-tsvwg-sctpsocket-07 revision.
I would like to know if there is any plan to upgrade the API from sctp.h in the near future, or if I would better start implementing my application using the current API. I am concerned also about interop problems, as my code should run on FreeBSD and other POSIX systems if possible. Would you have any advice, or any reference code for SCTP AUTH ?
