Current TKIP hwcrypto phase1+2 key support in d80211 seems to be broken. (At least for bcm43xx). Let me explain what happens: We need the phase1 for bcm43xx. We need to upload it to card memory and we need to pass it on every TX on the DMA. So, currently we receive the phase1 key on the first encrypted TX. That's too late, as we already receive encrypted packets before that. bcm43xx needs the phase1 key (and the iv32) on RX. It uses the one uploaded into the card memory. But it is not uploaded, yet, as we did not TX any encrypted packet. I'd say the only solution to this is to implement the earlier suggested way of having a library function call to generate the keys. Of course, that needs some bookkeeping about the IVs and stuff. That library function would be called by bcm43xx before any traffic to get an initial phase1 key (and iv32) uploaded. I currently don't really know how to implement this. Any suggestion? As a sideeffect, it would shrink the txcontrol by 16 bytes, again. -- Greetings Michael. - To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
