[PATCH 3.4 41/92] iwlwifi: dvm: fix D3 firmware PN programming

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Johannes Berg <johannes.berg@xxxxxxxxx>

3.4.112-rc1 review patch.  If anyone has any objections, please let me know.

------------------


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.
