sctp: rename enum sctp_event to sctp_event_type

2018-11-19T20:25:43Z

sctp_event is a structure name defined in RFC for sockopt SCTP_EVENT. To avoid the conflict, rename it. Signed-off-by: Xin Long Signed-off-by: David S. Miller

sctp: count both sk and asoc sndbuf with skb truesize and sctp_chunk size

2018-10-18T18:23:47Z

Now it's confusing that asoc sndbuf_used is doing memory accounting with SCTP_DATA_SNDSIZE(chunk) + sizeof(sk_buff) + sizeof(sctp_chunk) while sk sk_wmem_alloc is doing that with skb->truesize + sizeof(sctp_chunk). It also causes sctp_prsctp_prune to count with a wrong freed memory when sndbuf_policy is not set. To make this right and also keep consistent between asoc sndbuf_used, sk sk_wmem_alloc and sk_wmem_queued, use skb->truesize + sizeof(sctp_chunk) for them.

sctp: remove old and unused SCTP_MIN_PMTU

2018-04-27T18:35:22Z

This value is not used anywhere in the code. In essence it is a duplicate of SCTP_DEFAULT_MINSEGMENT, which is used by the stack. SCTP_MIN_PMTU value makes more sense, but we should not change to it now as it would risk breaking applications. So this patch removes SCTP_MIN_PMTU and adjust the comment above it.

sctp: implement assign_number for sctp_stream_interleave

2017-12-11T16:23:04Z

assign_number is added as a member of sctp_stream_interleave, used to assign ssn for data or mid (message id) for idata, called in sctp_packet_append_data. sctp_chunk_assign_ssn is left as it is, and sctp_chunk_assign_mid is added for sctp_stream_interleave_1. This procedure is described in section 2.2.2 of RFC8260. All sizeof(struct sctp_data_chunk) in tx path is replaced with sctp_datachk_len, to make it right for idata as well. And also adjust sctp_chunk_is_data for SCTP_CID_I_DATA. After this patch, idata can be built and sent in tx path. Note that if sp strm_interleave is set, it has to wait_connect in sctp_sendmsg, as asoc intl_enable need to be known after 4 shake- hands, to decide if it should use data or idata later. data and idata can't be mixed to send in one asoc.

sctp: remove the typedef sctp_subtype_t

2017-08-07T04:33:42Z

This patch is to remove the typedef sctp_subtype_t, and replace with union sctp_subtype in the places where it's using this typedef. Note that it doesn't fix many indents although it should, as sctp_disposition_t's removal would mess them up again. So better to fix them when removing sctp_disposition_t in later patch.
