Hi all,

I've got a question about the handling of SCTP_DELAYED_ACK.

In sctp_setsockopt_delayed_ack() the code looks to see if the size of
the struct being passed down matches the size of struct sctp_sack_info.
 If it doesn't, it accepts being passed struct sctp_assoc_value but it
complains about it.

However, the lksctp-tools package doesn't seem to define or use struct
sctp_sack_info anywhere, only struct sctp_assoc_value.

Are apps expected to copy the struct definition themselves?  Is there
any plan to update lksctp-tools?

Thanks,

Chris
