[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Robin Gögge <r.goegge@xxxxxxxxxxxxxx>

[ Upstream commit 78d14bda861dd2729f15bb438fe355b48514bfe0 ]

This patch fixes the probe for BPF_PROG_TYPE_CGROUP_SOCKOPT,
so the probe reports accurate results when used by e.g.
bpftool.
