This patchset is to improve the transmit err process and also fix some issues.
After this patchset, once the chunks are enqueued successfully, even if the chunks fail to send out, no matter because of nodst or nomem, no err retruns back to users any more. Instead, they are taken care of by retransmit. Xin Long (6): sctp: remove the unnecessary state check in sctp_outq_tail sctp: do not return the transmit err back to sctp_sendmsg sctp: free msg->chunks when sctp_primitive_SEND return err sctp: save transmit error to sk_err in sctp_outq_flush sctp: make sctp_outq_flush/tail/uncork return void sctp: not return ENOMEM err back in sctp_packet_transmit include/net/sctp/structs.h | 5 +-- net/sctp/chunk.c | 13 +++++++ net/sctp/output.c | 50 +++++++++++++------------- net/sctp/outqueue.c | 89 ++++++++++++++++------------------------------ net/sctp/sm_sideeffect.c | 25 +++++-------- net/sctp/socket.c | 6 ++-- 6 files changed, 84 insertions(+), 104 deletions(-) -- 2.1.0
