Description

This is the final part of #2867 which implements scatter/gather IO for platf::send_batch() and eliminates the frame copy in fec::encode() by FEC encoding and sending directly out of the payload buffer. This is done by introducing support for payload buffer lists containing multiple contiguous payloads buffers (necessary because data and parity shards are in different buffers). It also introduces the ability to begin sending messages from a specified offset which avoids having to adjust the buffer lists when we send a FEC block in multiple parts for frame pacing.

Testing checklist:

  • Linux sendmsg() + encryption
  • Linux sendmmsg() + encryption
  • Linux sendmsg() + no encryption
  • Linux sendmmsg() + no encryption
  • Windows WSASendMsg() + encryption
  • Windows WSASendMsg() + no encryption
  • Unbatched sends + encryption
  • Unbatched sends + no encryption

Description

This is the final part of #2867 which implements scatter/gather IO for platf::send_batch() and eliminates the frame copy in fec::encode() by FEC encoding and sending directly out of the payload buffer. This is done by introducing support for payload buffer lists containing multiple contiguous payloads buffers (necessary because data and parity shards are in different buffers). It also introduces the ability to begin sending messages from a specified offset which avoids having to adjust the buffer lists when we send a FEC block in multiple parts for frame pacing.

Testing checklist:

  • Linux sendmsg() + encryption
  • Linux sendmmsg() + encryption
  • Linux sendmsg() + no encryption
  • Linux sendmmsg() + no encryption
  • Windows WSASendMsg() + encryption
  • Windows WSASendMsg() + no encryption
  • Unbatched sends + encryption
  • Unbatched sends + no encryption
