This does not work with WE-18 and I would assume the same is true for
the previous patch since the problem is in the changes in wireless.h. It
looks like IW_EV_POINT_LEN changed and if wpa_supplicant is built with
wireless.h from v19, older versions do not work. This is quite
I did not realize that WE-19 is changing kernel-user space interface in
a backwards incompatible way. If I had, I would have objected to it.
Jean, have I misunderstood something or is this really changing the
event messages in a way that all user space programs need to be
recompiled or actually even worse, if they use IW_EV_POINT_LEN, modified
to support both old and new format and then recompiled? If that is the
case, was this change really needed?
