David Cermak c89a6389ed fix(lwip): Adds nullchecks after DHCP server alloc'd pools 2026-07-09 16:04:54 +02:00
David Cermak c8c3a30ec7 fix(lwip): reject invalid DHCP MTU option values 
Validate MTU from DHCP option 26 against RFC 2132 minimum (68 bytes)
before applying to netif->mtu, preventing rogue DHCP servers from
setting MTU to 0 or other dangerously low values that cause integer
wraparound in IPv4 fragmentation.

wangtao@espressif.com 29c12958cf feat(lwip): dhcp server add support for dhcp inform 2026-05-11 12:01:00 +08:00
David Cermak 315e3361c9 fix(lwip): Fix DHCP server potentially incomplete pbuf copy 
handle_dhcp: use pbuf_copy_partial for safe chain traversal

The manual two-segment copy loop was replaced with a single call
to pbuf_copy_partial(p, p_dhcps_msg, tlen, 0), which correctly
walks the entire pbuf chain regardless of segmentation.
A return-value check rejects truncated copies.

Frantisek Hrbata f50ae95ab5 fix(lwip/cmake): avoid using uninitialized srcs variable 
Currently, lwip's CMakeLists.txt might use an uninitialized srcs value
if CONFIG_LWIP_ENABLE is disabled. This means it could use a srcs value
set by another component, involving sources that are entirely
unrelated to the lwip component during registration. Perhaps we
should simply exit when CONFIG_LWIP_ENABLE is not enabled and avoid
registering the component altogether.

Amitesh Singh 201df702da feat(lwip/config): add menuconfig option for setting LWIP_IPV6_DUP_DETECT_ATTEMPTS 
In my network, ipv6 address allocation to esp32 was unreliable.
I'd to disable LWIP_IPV6_DUP_DETECT_ATTEMPTS to 0 to actually make
esp32 ipv6 address assignment work reliably.
