sctp_diag will dump some important details of sctp's assoc or ep, we use
sctp_info to describe them, sctp_get_sctp_info to get them, and export
it to sctp_diag.ko.

Can you double check to make sure this is 32 bit aligned
(no holes) maybe in your case 64 bit aligned?
Sticking + __u16 sctpi_p_error in there seems
to kill it.
Also, any plans to do the netlink events and destroy features?
cheers,
