This patchset introduces the SCTP Stream Schedulers are defined by https://tools.ietf.org/html/draft-ietf-tsvwg-sctp-ndata-13 It provides 3 schedulers at the moment: FCFS, Priority and Round Robin. The other 3, Round Robin per packet, Fair Capacity and Weighted Fair Capacity will be added later. More specifically, WFQ is required by WebRTC Datachannels. The draft also defines the idata chunk, allowing a usermsg to be interrupted by another piece of idata from another stream. This patchset *doesn't* include it. It will be posted later by Xin Long. Its integration with this patchset is very simple and it basically only requires a tweak in sctp_sched_dequeue_done(), to ignore datamsg boundaries. The first 5 patches are a preparation for the next ones. The most relevant patches are the 4th and 6th ones. More details are available on each patch. v2: changelog update on patch 3 Marcelo Ricardo Leitner (10): sctp: silence warns on sctp_stream_init allocations sctp: factor out stream->out allocation sctp: factor out stream->in allocation sctp: introduce struct sctp_stream_out_ext sctp: introduce sctp_chunk_stream_no sctp: introduce stream scheduler foundations sctp: add sockopt to get/set stream scheduler sctp: add sockopt to get/set stream scheduler parameters sctp: introduce priority based stream scheduler sctp: introduce round robin stream scheduler include/net/sctp/stream_sched.h | 72 +++++++++ include/net/sctp/structs.h | 63 +++++++- include/uapi/linux/sctp.h | 16 ++ net/sctp/Makefile | 3 +- net/sctp/chunk.c | 6 +- net/sctp/outqueue.c | 63 ++++---- net/sctp/sm_sideeffect.c | 3 + net/sctp/socket.c | 179 ++++++++++++++++++++- net/sctp/stream.c | 196 +++++++++++++++++++---- net/sctp/stream_sched.c | 275 +++++++++++++++++++++++++++++++ net/sctp/stream_sched_prio.c | 347 ++++++++++++++++++++++++++++++++++++++++ net/sctp/stream_sched_rr.c | 201 +++++++++++++++++++++++ 12 files changed, 1347 insertions(+), 77 deletions(-) create mode 100644 include/net/sctp/stream_sched.h create mode 100644 net/sctp/stream_sched.c create mode 100644 net/sctp/stream_sched_prio.c create mode 100644 net/sctp/stream_sched_rr.c -- 2.13.5 -- To unsubscribe from this list: send the line "unsubscribe linux-sctp" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
