I think this is due to my patch "iwlagn: rewrite HW crypto" which accidentally broke key *removal* (of all things), which causes issues when the first GTK is removed on the second rekeying. This patch http://git.kernel.org/?p=linux/kernel/git/iwlwifi/iwlwifi.git;a=commitdiff;h=5dcbf480473f6c3f06ad2426b7517038a2a18911 should fix it. Wey has sent it to John, but he hasn't picked it up yet for some reason -- it's also marked for stable. It'd be great to get confirmation that this is the problem, I'm not sure I'll find time today to reproduce the problem. johannes -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
