Ilja Van Sprundel reported that some size validations on inbound
SCTP packets were missing. After some code review, I noticed two
others that are all fixed here.

Thanks Ilja for reporting this.

Marcelo Ricardo Leitner (4):
  sctp: validate from_addr_param return
  sctp: add size validation when walking chunks
  sctp: validate chunk size in __rcv_asconf_lookup
  sctp: add param size validation for SCTP_PARAM_SET_PRIMARY
