Just to make sure everybody is aware that it would only be a partial fix
- unencrypted ad hoc mode (the simplest thing available) doesn't need
any userspace and thus must be fixed in the kernel. Alternatively this
functionality may be moved to wpa_supplicant and only then userspace fix
could really fix it completely.
