./api/sockets.c: In function 'lwip_getsockopt_impl':
./api/sockets.c:1892:12: warning: large integer implicitly truncated
to unsigned type [-Woverflow]
return EBADF;
Joan,
the return type is related to the type of struct lwip_sock's 'err' member.
reading the comment /** last error that occurred on this socket (in
fact, all our errnos fit into an u8_t) */

definitions but might not

Please, take a look at this thread:

I've changed return type to u32_t and have also
