From: Geliang Tang <tanggeliang@kylinos.cn>
v10:
- drop mptcp_subflow_set_scheduled() helper and WRITE_ONCE() in BPF.
- add new bpf helper bpf_mptcp_send_info_to_ssk() for burst scheduler.
v9:
- merge 'Fixes for "use bpf_iter in bpf schedulers" v8' into this set.
- rebased on "add netns helpers" v4
v8:
- address Mat's comments in v7.
- move sk_stream_memory_free check inside bpf_for_each() loop.
- implement mptcp_subflow_set_scheduled helper in BPF.
- add cleanup patches into this set again.
v7:
- move cleanup patches out of this set.
- rebased.
v6:
- rebased to "add mptcp_subflow bpf_iter" v10
v5:
- patch 2, drop mptcp_sock_type and mptcp_subflow_type.
- patch 3, revert "bpf: Export more bpf_burst related functions"
- patch 4, merge "bpf: Export more bpf_burst related functions" into it.
v4:
- patch 2, a new cleanup for "bpf: Add bpf_mptcp_sched_ops".
- patch 3 should be reverted.
- patch 8, register kfunc_set.
v3:
- rebased.
- put the "drop has_bytes_sent" squash-to patch into this set.
v2:
- update bpf_rr and bpf_burst
With the newly added mptcp_subflow bpf_iter, we can get rid of the
subflows array "contexts" in struct mptcp_sched_data. This set
uses bpf_for_each(mptcp_subflow) helper to update all the bpf
schedules:
bpf_for_each(mptcp_subflow, subflow, msk) {
... ...
mptcp_subflow_set_scheduled(subflow, true);
}
