Detailed Description

IPv6 version of ICMP, as per RFC 4443.

Definition in file lwip_icmp6.c.

Function Documentation

void icmp6_dest_unreach ( struct pbuf *  p,
enum icmp6_dur_code  c 
)

Send an icmpv6 'destination unreachable' packet.

Parameters:
pthe input packet for which the 'unreachable' should be sent, p->payload pointing to the IPv6 header
cICMPv6 code for the unreachable type

Definition at line 217 of file lwip_icmp6.c.

void icmp6_input ( struct pbuf *  p,
struct netif *  inp 
)

Process an input ICMPv6 message.

Called by ip6_input.

Will generate a reply for echo requests. Other messages are forwarded to nd6_input, or mld6_input.

Parameters:
pthe mld packet, p->payload pointing to the icmpv6 header
inpthe netif on which this packet was received

Definition at line 81 of file lwip_icmp6.c.

void icmp6_packet_too_big ( struct pbuf *  p,
u32_t  mtu 
)

Send an icmpv6 'packet too big' packet.

Parameters:
pthe input packet for which the 'packet too big' should be sent, p->payload pointing to the IPv6 header
mtuthe maximum mtu that we can accept

Definition at line 230 of file lwip_icmp6.c.

void icmp6_param_problem ( struct pbuf *  p,
enum icmp6_pp_code  c,
u32_t  pointer 
)

Send an icmpv6 'parameter problem' packet.

Parameters:
pthe input packet for which the 'param problem' should be sent, p->payload pointing to the IP header
cICMPv6 code for the param problem type
pointerthe pointer to the byte where the parameter is found

Definition at line 257 of file lwip_icmp6.c.

static void icmp6_send_response ( struct pbuf *  p,
u8_t  code,
u32_t  data,
u8_t  type 
) [static]

Send an ICMPv6 packet in response to an incoming packet.

Parameters:
pthe input packet for which the response should be sent, p->payload pointing to the IPv6 header
codeCode of the ICMPv6 header
dataAdditional 32-bit parameter in the ICMPv6 header
typeType of the ICMPv6 header

Definition at line 272 of file lwip_icmp6.c.

void icmp6_time_exceeded ( struct pbuf *  p,
enum icmp6_te_code  c 
)

Send an icmpv6 'time exceeded' packet.

Parameters:
pthe input packet for which the 'unreachable' should be sent, p->payload pointing to the IPv6 header
cICMPv6 code for the time exceeded type

Definition at line 243 of file lwip_icmp6.c.
