HI Chih-Wei/group
I debugged the code in system/core/libnetutils/dhcp_utils.c
it shows the except dsn1 and dsn2 other property is not set. So I am
seeing valid values for dsn1 and dsn2.
P configuration: ipaddr 0.0.0.0 gateway 0.0.0.0 netmask 0.0.0.0 dns1
10.50.201.5 dns2 125.22.47.125 DHCP server 0.0.0.0 lease -1398609015
seconds
static void fill_ip_info(const char *interface,
in_addr_t *ipaddr,
in_addr_t *gateway,
in_addr_t *mask,
in_addr_t *dns1,
in_addr_t *dns2,
in_addr_t *server,
uint32_t *lease)
{
char prop_name[PROPERTY_KEY_MAX];
char prop_value[PROPERTY_VALUE_MAX];
struct in_addr addr;
in_addr_t iaddr;
snprintf(prop_name, sizeof(prop_name), "%s.%s.ipaddress",
DHCP_PROP_NAME_PREFIX, interface);
if (property_get(prop_name, prop_value, NULL) &&
inet_aton(prop_value, &addr)) {
*ipaddr = addr.s_addr;
} else {
*ipaddr = 0;
}
snprintf(prop_name, sizeof(prop_name), "%s.%s.gateway",
DHCP_PROP_NAME_PREFIX, interface);
if (property_get(prop_name, prop_value, NULL) &&
inet_aton(prop_value, &addr)) {
*gateway = addr.s_addr;
} else {
*gateway = 0;
}
snprintf(prop_name, sizeof(prop_name), "%s.%s.mask",
DHCP_PROP_NAME_PREFIX, interface);
if (property_get(prop_name, prop_value, NULL) &&
inet_aton(prop_value, &addr)) {
*mask = addr.s_addr;
} else {
*mask = 0;
}
snprintf(prop_name, sizeof(prop_name), "%s.%s.dns1",
DHCP_PROP_NAME_PREFIX, interface);
if (property_get(prop_name, prop_value, NULL) &&
inet_aton(prop_value, &addr)) {
*dns1 = addr.s_addr;
} else {
*dns1 = 0;
}
snprintf(prop_name, sizeof(prop_name), "%s.%s.dns2",
DHCP_PROP_NAME_PREFIX, interface);
if (property_get(prop_name, prop_value, NULL) &&
inet_aton(prop_value, &addr)) {
*dns2 = addr.s_addr;
} else {
*dns2 = 0;
}
snprintf(prop_name, sizeof(prop_name), "%s.%s.server",
DHCP_PROP_NAME_PREFIX, interface);
if (property_get(prop_name, prop_value, NULL) &&
inet_aton(prop_value, &addr)) {
*server = addr.s_addr;
} else {
*server = 0;
}
snprintf(prop_name, sizeof(prop_name), "%s.%s.leasetime",
DHCP_PROP_NAME_PREFIX, interface);
if (property_get(prop_name, prop_value, NULL)) {
*lease = atol(prop_value);
}
}
Who will set these property? Where I need to debug and whether I need
to modify configuration information?
Thanks
