udhcpc6: fix udhcp_find_option to actually find DHCP6 options
udhcp_insert_new_option treats code for IPv6 as follows: new->data[D6_OPT_CODE] = code >> 8; new->data[D6_OPT_CODE + 1] = code & 0xff; udhcp_find_option tests the code as follows: while (opt_list && opt_list->data[OPT_CODE] < code) ... if (opt_list && opt_list->data[OPT_CODE] == code) So yes, OPT_CODE and D6_OPT_CODE are both 0, but the D6_OPT_CLIENTID = 1 value means that the 1 is in the seconds byte, and udhcp_find_option is only looking at the first byte, So the send_d6_release can never find it the created option. function old new delta udhcp_find_option 28 53 +25 attach_option 276 284 +8 udhcpc6_main 2602 2607 +5 perform_d6_release 262 267 +5 udhcpd_main 1518 1520 +2 udhcpc_main 2542 2544 +2 add_serverid_and_clientid_options 46 48 +2 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 7/0 up/down: 49/0) Total: 49 bytes Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
