lwip/dhcpserver: Support for adding extra opts
...
This enables users appending an extra, user defined options in dhcp
server messages. Example of adding captive_portal option (160) to dhcp
offer message is provided:
* Add idf-lwip hook file (project makefile):
idf_component_get_property(lwip lwip COMPONENT_LIB)
target_compile_options(${lwip} PRIVATE "-I${PROJECT_DIR}/main")
target_compile_definitions(${lwip} PRIVATE "-DESP_IDF_LWIP_HOOK_FILENAME=\"add_captive_portal.h\"")
* Implement appending (add_captive_portal.h):
#pragma once
#define LWIP_HOOK_DHCPS_POST_APPEND_OPTS(netif, dhcp, state, pp_opts) \
if ((state)==DHCPOFFER) { *(pp_opts) = append_captive_portal_uri(*(pp_opts)); }
static inline uint8_t *append_captive_portal_uri(uint8_t *optptr)
{
const static uint8_t DHCP_OPTION_CAPTIVE_PORTAL=160;
const static char CAPTIVE_PORTAL_URI[]="my_uri";
int size = sizeof(CAPTIVE_PORTAL_URI) - 1;
*optptr++ = DHCP_OPTION_CAPTIVE_PORTAL;
*optptr++ = size;
for(int i = 0; i < size; ++i) {
*optptr++ = CAPTIVE_PORTAL_URI[i];
}
return optptr;
}

lwip: Fix DHCP Server to remove clients record if request not acked
...
When client's request refused by sending NAK, its record still resided
in the linked list of pooled addresses. It is okay from the spec
perspective (RFC2131.p16: Server MAY mark the offered address
unavailable), but would consume some memory if the client didn't retry.
