I've got a stock Fedora Core 13 install (updated today) with the hostapd-0.6.10 rpm and hostapd-0.7.2 compiled from sources. The NIC is a Ubiquiti SR71e (AR9280). I installed compat-wireless-2010-08-19 after patching it with Johannes's fix posted earlier today. I can confirm that hostapd and iw are no longer hitting the "Illegal nla->nla_type == 0" message when run. But I'm seeing something else. (1) "Unknown event 5" messages when starting up hostapd (line 95 below): (2) Some highly unlikely values from the hostapd debugging messages when parsing out WEP authentication messages (line 507): This is captured in http://pastebin.ca/1924659 : authentication: STA=f8:1e:df:1e:c2:23 auth_alg=35510 auth_transaction=79 status_code=21688 wep=1 Unsupported authentication algorithm (35510) I'm wondering if some messages that are passed up to user-space via netlink from the driver might have changed their schema, i.e. adding new fields in the middle of a structure or moving fields around within a structure. Am I on the wrong track? How to go about resolving this?
