Subject: [PATCH] batman-adv: Fix speedy join in gateway client mode
|
|
|
|
Speedy join only works when the received packet is either broadcast or an
|
|
4addr unicast packet. Thus packets converted from broadcast to unicast via
|
|
the gateway handling code have to be converted to 4addr packets to allow
|
|
the receiving gateway server to add the sender address as temporary entry
|
|
to the translation table.
|
|
|
|
Not doing it will make the batman-adv gateway server drop the DHCP response
|
|
in many situations because it doesn't yet have the TT entry for the
|
|
destination of the DHCP response.
|
|
|
|
Fixes: 9cbc67d9da47 ("batman-adv: change interface_rx to get orig node")
