With the changes in wpa_supplicant/events.c, the likelihood of that getting anywhere is about zero, but if the driver specific changes were to be moved to src/drivers/driver_nl80211.c, this could be quite a reasonable change to include in the upstream tree. Note the global_init() and init2() struct wpa_driver_ops callbacks that should make it easy to track the interfaces within driver_nl80211.c. I would like to have more knowledge of virtual interfaces sharing the same radio in the driver wrappers anyway, e.g., for shared_freq() implementations. If this can be reliably detected from the driver (which hopefully is the case with mac80211-based ones), it would be great to be able to that without having to ask the user to configure anything. > I know I need to at least strip out some of the debug code, and make > this optional via the global config file, but I was hoping early feedback > might save more work later... What would be need for configuring this? In which case would it be preferred to not process the scan results from other virtual interfaces on the same radio? Wouldn't those scan events look exactly like the same if some other application would have triggered them? In addition, it might be interesting to considering sharing the BSS table and scan result parsing in wpa_supplicant among the interface, too, instead of just the scan completed events.. -- Jouni Malinen PGP id EFC895FA -- 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
