We notice a strange problem when receiving ath10k frames in raw mode (with modified firmware).
The very first data message (UDP discovery response) is dropped in WPA2 + AES mode, and it appears that if we would set the RX_FLAG_ALLOW_SAME_PN it would be accepted. ath9k in software-crypt mode does not have this issue as far as we can tell. So, maybe ath10k should set this flag?? Here is commit ID from the logic that introduced this flag, in case that helps jog some memory. commit f631a77ba920f7153a1094d09cd8f2ebbffd0328 Author: Sara Sharon <[email protected]> Date: Tue May 3 15:59:44 2016 +0300 mac80211: allow same PN for AMSDU sub-frames Some hardware (iwlwifi an example) de-aggregate AMSDUs and copy the IV as is to the generated MPDUs, so the same PN appears in multiple packets without being a replay attack. Allow driver to explicitly indicate that a frame is allowed to have the same PN as the previous frame.
