Subject: [PATCH bpf-next v2 0/2] Align BPF TCP CCs implementing cong_control() with non-BPF CCs
Date: Thu, 9 Jun 2022 22:47:00 +0200	[thread overview]
Message-ID: <20220609204702.2351369-1-jthinz@mailbox.tu-berlin.de> (raw)
In-Reply-To: <20220608174843.1936060-1-jthinz@mailbox.tu-berlin.de>

This small series corrects some inconveniences for a BPF TCP CC that
implements and uses tcp_congestion_ops.cong_control(). Until now, such a
CC did not have all necessary write access to struct sock and
unnecessarily needed to implement cong_avoid().

---
v2:
 - Drop redundant check for required functions and just rely on
   tcp_register_congestion_control() (Martin KaFai Lau)

Jörn-Thorben Hinz (2):
  bpf: Allow a TCP CC to write sk_pacing_rate and sk_pacing_status
  bpf: Require only one of cong_avoid() and cong_control() from a TCP CC
