Please find this patch that controls the length of OPTION_RECONF_ACCEPT (20).
Like defined by RFC3315, its length has to be 0.
Excerpt RFC3315:
22.20. Reconfigure Accept Option
A client uses the Reconfigure Accept option to announce to the server
whether the client is willing to accept Reconfigure messages, and a
server uses this option to tell the client whether or not to accept
Reconfigure messages. The default behavior, in the absence of this
option, means unwillingness to accept Reconfigure messages, or
instruction not to accept Reconfigure messages, for the client and
server messages, respectively. The following figure gives the format
of the Reconfigure Accept option:
0 1 2 3
0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1
