Subject: [PATCH 0/3] first step towards GTK rekey offload
Date: Tue, 05 Jul 2011 16:35:38 +0200 [thread overview]
Message-ID: <20110705143538.696899280@sipsolutions.net> (raw)
These patches are a first step to allow devices
to implement GTK rekeying while suspended (or
really at any time).
The key iteration (first patch) is necessary as
we need to load a different firmware image, and
I don't want to do double-bookkeeping (tracking
all keys in the driver).
The second and third patch allow wpa_supplicant
to give the necessary information to the driver
to implement GTK rekeying.
Note that for iwlwifi this isn't yet sufficient
as it also needs access to the CCMP PN/TKIP IVs
to encrypt the GTK rekey reply frame correctly.
However, I have only tested with CCMP so I'll
submit those patches only when I've also tested
TKIP.
