DHCPv6 Client "Malformed packet"

Reported by: vladkansk@… Owned by: developers
Priority: normal Milestone: Barrier Breaker 14.07
Component: packages Version: Barrier Breaker 14.07
Keywords: Cc:

Description

My router is TP-Link TL-WR1043N/ND v1.
Firmware Version: OpenWrt Barrier Breaker 14.07-rc2 / LuCI Trunk (svn-r10459)

DHCPv6-client works only without DHCPv6-PD (option reqprefix disabled)
When I try to get DHCPv6-PD (/64 or auto) I get Malformed packet from router.

config:
config interface 'wan6'

option ifname '@wan'
option proto 'dhcpv6'
option reqaddress 'force'
option reqprefix '64'

Did you build the image yourself? I just tried with the prebuilt images on a WNDR3800 (same architecture) and couldn't reproduce this.

Yeah I used the same image just the one for wndr3800 which should be identical aside from some headers. Very strange.

comment:5 Changed 4 years ago by Vladkansk

I've just installed same build to Mikrotik http://downloads.openwrt.org/barrier_breaker/14.07-rc2/ar71xx/mikrotik/openwrt-ar71xx-mikrotik-vmlinux-lzma.elf + http://downloads.openwrt.org/barrier_breaker/14.07-rc2/ar71xx/mikrotik/openwrt-ar71xx-mikrotik-DefaultNoWifi-rootfs.tar.gz
And I have almost same problem.
No I have normal Solicit for address, but Malformed packet after that and I think this packet for DHCPv6-PD
