Building bpf selftests with clang can trigger errors like the following:

CLNG-BPF [test_maps] bpf_iter_netlink.bpf.o progs/bpf_iter_netlink.c:32:4: error: incompatible pointer types assigning to 'struct sock *' from 'struct sock___17 *' [-Werror,-Wincompatible-pointer-types] s = &nlk->sk; ^ ~~~~~~~~ 1 error generated.

I cannot reproduce this and BPF CI doesn't complain about it either. What kind of clang do you use? Some special version and build flags?
