Hi All, Hi I'm studying code for ICMP . there is a piece of code in icmp_input which just returns when we find the ICMP packet length lesser than allowed.
if (icmplen < ICMP_MINLEN) { icmpstat.icps_tooshort++; goto freeit; } i = hlen + min(icmplen, ICMP_ADVLENMIN); if (m->m_len < i && (m = m_pullup(m, i)) == 0) { icmpstat.icps_tooshort++; return; } where #define ICMPADVELMIN (8 + sizeof(struct ip) + 8) and icmplen = ip->ip_len ; why the return? Shouldn't there be a freeing of the msg.i.e call the m_freem(m) instead of return ? Can anybody please shed light on this ? Thanks.
