[ath9k-devel] AuthSAE rekeying issues with ATH9K

Hey Adrian,

Just saw your email, I took a quick look and I was able to find a struct ieee80211_key_conf which contains the key material.
I suppose that the ath_node needs to be extracted from the ieee80211_sta -> drv_priv by looking up the source mac address in the struct ieee80211_hdr somewhere in ath9k_rx_accept()?
The ath_node could then give the ps_key which contains the key cache index. This function also houses decrypt_errors which could be used for detection.

I suppose that ieee80211_find_sta_by_ifaddr( ) with the destination and source mac as arguments would nicely fit the bill.
The struct ath_node could also contain the key material, which could then be used for the replumbing.

Any particular pattern I must follow when writing the key material? Or will ath_key_delete( ) followed by a ath_hw_set_keycache_entry( ) suffice?

Kind regards,

Michel Stam
