Subject: [PATCH 3.10 03/24] iwlwifi: mvm: fix D3 firmware PN programming
3.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Johannes Berg <johannes.berg@...el.com>
commit 2cf5eb3ab7bb7f2e3a70edcef236cd62c87db030 upstream.
The code to send the RX PN data (for each TID) to the firmware
has a devastating bug: it overwrites the data for TID 0 with
all the TID data, leaving the remaining TIDs zeroed. This will
allow replays to actually be accepted by the firmware, which
could allow waking up the system.
