[lwip-devel] [bug #29072] DHCPDISCOVER doesn't have ciaddr == 0

[Simon Goldschmidt]

Update of bug #29072 (project lwip):

             Assigned to:                    None => goldsimon

Follow-up Comment #1:

I'd fix this by passing the message-type to dhcp_create_request and basing
the choice (whether to set ciaddr to zero or use netif->ip_addr) on the
message-type instead of the current state.

BTW: RFC2131 4.4.1 Table 5 doesn't mention the INIT-REBOOT or REBOOT state
regarding ciaddr/DHCPREQUEST, but I guess it's OK to set the client's address
there, too...?

None that I know of. Currently, you have to call dhcp_stop() on your own.
