Title: receive of unexpected chunks with invalid parameters

Dear all,

Question to unexpected chunks with invalid mandatory parameters (e.g. MIS=0, OS=0, Init-Tag=0):
As far as I understand the sctp.de implementation, it is possible to attack a running association with e.g. an INIT and invalid mandatory parameters. After receive of that unexpected chunks the prototype does delete the running association (pre 16: sctp-control.c, func scr_init, line 677). Is that a correct behaviour according to RFC?
