Or wait ... are you using compat-wireless?

Yes, I am. I mentioned this and did wonder if the _backport/ part
in /sys/class is important.

Sorry, didn't see.

Anyway, that's pretty clearly the reason -- Luis added NETDEV_PRE_UP to
some compat*.h but obviously the kernel won't ever call that notifier,
so cfg80211 doesn't get a chance to reject the IFUP. No idea how to
handle that -- it'll be working fine in a regular tree.

Luis, the only way to handle that would be to manually call the PRE_UP
notifier from mac80211's subif_open() and if that returns an error
(warning: the calling convention is weird) return the error... that's
weird but would work.

Okay, that explains it. So I can have a Tested-by: ... I just grep for

Ok, I submitted now the patches.

NETDEV_PRE_UP in compat-wireless and it is only in
include/net/compat-2.6.31.h (not in 2.6.30) and I am on 2.6.30.5-X . I
can grab the rawhide 2.6.31 rpms and try it quickly;
and possibly look at some ugly quick hack backport that? Stay tuned.

Thanks for the help.
