[PATCH mptcp-next v4 0/5] BPF redundant scheduler

Posted by Geliang Tang 3 years, 3 months ago

v4:
 - small cleanups in patch 1, 2.
 - add TODO in patch 3.
 - rebase patch 5 on 'cleanups for bpf sched selftests'.

v3:
 - use new API.
 - fix the link failure tests issue mentioned in ("https://patchwork.kernel.org/project/mptcp/cover/cover.1653033459.git.geliang.tang@suse.com/").

v2:
 - add MPTCP_SUBFLOWS_MAX limit to avoid infinite loops when the
   scheduler always sets call_again to true.
 - track the largest copied amount.
 - deal with __mptcp_subflow_push_pending() and the retransmit loop.
 - depends on "BPF round-robin scheduler" v14.

v1:

Implements the redundant BPF MPTCP scheduler, which sends all packets
redundantly on all available subflows.

Geliang Tang (5):
  Squash to "mptcp: add get_subflow wrappers"
  mptcp: add __mptcp_sched_get_retrans wrapper
  mptcp: add mptcp_sched_get_send wrapper
  selftests/bpf: Add bpf_red scheduler
  selftests/bpf: Add bpf_red test
