<div dir="ltr"><div>Personally I think the odds that someone would do a disassociation attack to monitor or SSH into the laptops of Sugar-age students are low enough that it isn't worth designing for. I do not know of any consumer product which currently tries to guard against being forced to search for another network to use.<br>
<br>But it would be useful to have the ability to "lock" to a network (AP, ad-hoc, or otherwise), and not resort to searching NetworkManager's known/preferred list if communication is temporarily lost.<br></div>
<div><br></div><div>5 GHz ad-hoc is slightly tricky in that there are only a few channels (36/40/44/48) one can manually select; the rest may only be selected via automatic means. According to Wikipedia[*] they seem to be reasonably well accepted -- but in some countries they may only be used indoors (so no "under the tree").<br>

I've reviewed the patches.<br>
<br>
I don't think this is worth breaking API and string freeze, as both<br>
are new features.<br>
<br>
I'd like to see them go through the new feature design process.<br>
<br>
In reviewing the patches, two more new features came to mind:<br>
<br>
- use higher bandwidth 5 GHz channels for ad-hoc, not only the<br>
channels 1, 6, and 11,<br>
<br>
- secured ad-hoc.<br>
<br>
With ad-hoc enabled a remote attacker need only transmit packets that<br>
prevent use of an access point, and the laptop will revert to<br>
unsecured ad-hoc, and begin to reveal useful data to an attacker.<br>
