From 45a7943d9fed337807ce04654d1a6bbf3ae746e0 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Tue, 15 Sep 2015 14:36:09 +0200 Subject: [PATCH] iwlwifi: dvm: fix D3 firmware PN programming commit 5bd166872d8f99f156fac191299d24f828bb2348 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.
