Adding selftests for the newly added functionality to call bpf_setsockopt() and bpf_getsockopt() from setsockopt BPF programs. Test Details: 1. BPF Program Checks for changes in IPV6_TCLASS(SOL_IPV6) via setsockopt If the cca for the socket is not cubic do nothing If the newly set value for IPV6_TCLASS is 45 (0x2d) (as per our use-case) then change the cc from cubic to reno 2. User Space Program Creates an AF_INET6 socket and set the cca for that to be "cubic" Attach the program and set the IPV6_TCLASS to 0x2d using setsockopt Verify the cca for the socket changed to reno Signed-off-by: Prankur Gupta <prankgup@fb.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Acked-by: Song Liu <songliubraving@fb.com> Link: https://lore.kernel.org/bpf/20210817224221.3257826-3-prankgup@fb.com |
