Prankur Gupta 2c531639de bpf: Add support for {set|get} socket options from setsockopt BPF ... Add logic to call bpf_setsockopt() and bpf_getsockopt() from setsockopt BPF programs. An example use case is when the user sets the IPV6_TCLASS socket option, we would also like to change the tcp-cc for that socket. We don't have any use case for calling bpf_setsockopt() from supposedly read- only sys_getsockopt(), so it is made available to BPF_CGROUP_SETSOCKOPT only at this point.
