How about linux 4.9 below, are they compliant with 802.11 standard or not?
They are compliant.
Would they need additional patches to mitigate the aggregation attack?
They need the backport of "[PATCH 04/18] cfg80211: mitigate A-MSDU aggregation attacks" to mitigate attacks. This patch has been backported to 4.4: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h= v4.4.275&id=daea7ff51861cec93ff7f561095d9048b673b51f
So if you take all the patches that have been backported to 4.4 you should be OK.
Cheers, Mathy
I get it now, thanks.
