bpf: NULL pointer check is not needed in BPF_CGROUP_RUN_PROG_INET_SOCK sk is already allocated in inet_create/inet6_create, hence when BPF_CGROUP_RUN_PROG_INET_SOCK is executed sk will never be NULL. The logic is as bellow, sk = sk_alloc(); if (!sk) goto out; BPF_CGROUP_RUN_PROG_INET_SOCK(sk); Signed-off-by: Yafang Shao <laoar.shao@gmail.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>
