| Thread-topic: | Problem with ebtables target that changes frame protocol |
|
I have written an
ebtables target that changes the ethernet protocol of a received frame (it runs
in the broute chain). I have been working on 2.4.21 sources - Unfortunately
inside netif_rx the skb->protocol is looked at before the bridge code is
called - and then acted upon after. Hence if the bridge code changes the
protocol the incorrect protocol is used to process the
frame.
