<p>Due to the asynchronous nature of GNRC this is deactivated by default. There is however the poorly utilized, poorly tested and poorly documented <a href="https://doc.riot-os.org/group__net__gnrc__neterr.html" rel="nofollow"><code>gnrc_neterr</code> module</a> which could provide such error reporting for sock. At least most releases in IPv6 are using <code>gnrc_pktbuf_release_error()</code> to signal an error.</p>
