Detailed Description
Definition in file lwip_dhcp6.c.
Enumeration Type Documentation
| enum dhcp6_option_idx |
Option handling: options are parsed in dhcp6_parse_reply and saved in an array where other functions can load them from.
This might be moved into the struct dhcp6 (not necessarily since lwIP is single-threaded and the array is only used while in recv callback).
Definition at line 96 of file lwip_dhcp6.c.

| static struct pbuf* dhcp6_create_msg | ( | struct netif * | netif, |
| struct dhcp6 * | dhcp6, | ||

Create a DHCPv6 request, fill in common headers.
- Parameters:
-
netif the netif under DHCPv6 control dhcp6 dhcp6 control struct message_type message type of the request opt_len_alloc option length to allocate options_out_len option length on exit
- Returns:
- a pbuf for the message
Definition at line 377 of file lwip_dhcp6.c.
| static void dhcp6_dec_pcb_refcount | ( | void | ) | [static] |
Free DHCP PCB if the last netif stops using it.
Definition at line 165 of file lwip_dhcp6.c.
| static err_t dhcp6_inc_pcb_refcount | ( | void | ) | [static] |
Ensure DHCP PCB is allocated and bound.
Definition at line 139 of file lwip_dhcp6.c.
| void dhcp6_nd6_ra_trigger | ( | struct netif * | netif, |
| u8_t | managed_addr_config, | ||
| u8_t | other_config | ||
| ) |
This function is called from nd6 module when an RA messsage is received It triggers DHCPv6 requests (if enabled).
Definition at line 577 of file lwip_dhcp6.c.
Parse the DHCPv6 message and extract the DHCPv6 options.
Extract the DHCPv6 options (offset + length) so that we can later easily check for them or extract the contents.
Definition at line 608 of file lwip_dhcp6.c.
| static void dhcp6_timeout | ( | struct netif * | netif, |
| struct dhcp6 * | dhcp6 | ||
| ) | [static] |
A DHCPv6 request has timed out.
The timer that was started with the DHCPv6 request has timed out, indicating no response was received in time.
Definition at line 766 of file lwip_dhcp6.c.
| void dhcp6_tmr | ( | void | ) |
DHCPv6 timeout handling (this function must be called every 500ms, see DHCP6_TIMER_MSECS).
A DHCPv6 server is expected to respond within a short period of time. This timer checks whether an outstanding DHCPv6 request is timed out.
Definition at line 790 of file lwip_dhcp6.c.
Variable Documentation
| struct dhcp6_option_info dhcp6_rx_options[DHCP6_OPTION_IDX_MAX] |
Holds the decoded option info, only valid while in dhcp6_recv.
