sctp: delete the obsolete code for the host name address param

2023-04-17T07:28:20Z

In the latest RFC9260, the Host Name Address param has been deprecated. For INIT chunk: Note 3: An INIT chunk MUST NOT contain the Host Name Address parameter. The receiver of an INIT chunk containing a Host Name Address parameter MUST send an ABORT chunk and MAY include an "Unresolvable Address" error cause. For Supported Address Types: The value indicating the Host Name Address parameter MUST NOT be used when sending this parameter and MUST be ignored when receiving this parameter. Currently Linux SCTP doesn't really support Host Name Address param, but only saves some flag and print debug info, which actually won't even be triggered due to the verification in sctp_verify_param(). This patch is to delete those dead code. Signed-off-by: Xin Long Signed-off-by: David S. Miller

sctp: add weighted fair queueing stream scheduler

2023-03-09T10:31:44Z

As it says in rfc8260#section-3.6 about the weighted fair queueing scheduler: A Weighted Fair Queueing scheduler between the streams is used. The weight is configurable per outgoing SCTP stream. This scheduler considers the lengths of the messages of each stream and schedules them in a specific way to use the capacity according to the given weights. If the weight of stream S1 is n times the weight of stream S2, the scheduler should assign to stream S1 n times the capacity it assigns to stream S2. The details are implementation dependent. Interleaving user messages allows for a better realization of the capacity usage according to the given weights. This patch adds Weighted Fair Queueing Scheduler actually based on the code of Fair Capacity Scheduler by adding fc_weight into struct sctp_stream_out_ext and taking it into account when sorting stream-> fc_list in sctp_sched_fc_sched() and sctp_sched_fc_dequeue_done().
