I have encountered kernel crash when I have used mesh SAE connection with ath9k_htc device (Sony UWA-BR100). I have tried to connect 2 peers to each other, then only one peer crashes.

By bisect, this commit looks causes this issue.

    mac80211: Ensure enough headroom when forwarding mesh pkt

    When a buffer is duplicated during MESH packet forwarding,
    this patch ensures that the new buffer has enough headroom.

I do not have any crash log because the computer was fully uncontrollable.

Masashi Honma.
