[B.A.T.M.A.N.] adding mac address field to orig_node struct

Hi

[1] I am using batmand, I have added the following field to the orig_node struct in batman.h:

char * mac_addr;

[2] In get_orig_node() in originator.c:

orig_node->mac_addr = (char *)malloc(30 * sizeof(char)); memset(orig_node->mac_addr, 0, 30);

[3] Problem: When I update this field in isbidirectional() in batman.c:

memcpy(orig_neigh_node->mac_addr, mac_addr_1, strlen(mac_addr_1));

it updates the field fine, but it does not persist, that is to say that after receiving another OGM from the same station, orig_neigh_node->mac_addr is empty. I dont understand why this should be happening.

Thanks
