Hi, I try to resize the payload of TCP packed but i can't. I don't know if this is the right way? This is the part of code: len = nfq_get_payload(nfa, &full_packet); struct ip *iphdr = (struct ip *) full_packet; int iphlen = iphdr->ip_hl<<2; struct tcphdr *tcp = (struct tcphdr *)((caddr_t )iphdr + iphlen); unsigned char *pl_data = (void *)tcp + (tcp->doff*4)+32; ... pl_data = realloc(pl_data, (strlen((char *)pl_data) ) + (sizeof(char) * strlen(m))+1 ); ... This part of code works only sometimes and some others fails with invalid pointer Can i use realloc to allocate more memory in this case? How can i allocate more memory for the payload? I don't know if is the correct mailing list for this kind of questions? If not, there's another list available?
