> Ok, so the problem is with lwIP's `sock` implementation. That at least tells me, that `sock` is not completely broken ;-). As to `sys_arch_mbox_fetch`: It is very similar to what `gnrc_sock_recv()` does in `gnrc_sock.c` (the first is just more generalized). Could you check if there is any significant difference (e.g. #16831 was merged recently there) that could make a difference in your case? Maybe it is about time we add a `xtimer`/`ztimer` function for that kind of functionality (`xtimer_mbox_get_timeout()`...).

I'll have a look into it
