From 02c558b2d5d679fbbcaa5b9689484c7e0f8abb7b Mon Sep 17 00:00:00 2001 From: John Fastabend Date: Tue, 16 Oct 2018 11:08:04 -0700 Subject: bpf: sockmap, support for msg_peek in sk_msg with redirect ingress This adds support for the MSG_PEEK flag when doing redirect to ingress and receiving on the sk_msg psock queue. Previously the flag was being ignored which could confuse applications if they expected the flag to work as normal.
