    Subject[PATCH 3.16 283/357] ath9k_htc: fix random decryption failure
    Date
    3.16-stable review patch.  If anyone has any objections, please let me know.

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

    From: Johannes Stezenbach <js@sig21.net>

    commit d21ccfd0a60ea3dece3e1d142f52694abf87a0b1 upstream.

    In v3.15 the driver stopped to accept network packets after successful
    authentification, which could be worked around by passing the
    nohwcrypt=1 module parameter. This was not reproducible by
    everyone, and showed random behaviour in some tests.
    It was caused by an uninitialized variable introduced
    in 4ed1a8d4a257 ("ath9k_htc: use ath9k_cmn_rx_accept") and
    used in 341b29b9cd2f ("ath9k_htc: use ath9k_cmn_rx_skb_postprocess").
