Wouldn't it possible to iterater in an sorted order? As you noted
in your other email the patch uses a bit of ducktape to address
the problem.
Thanks,

Many thanks to the bug report. Looking at the wpa_supplicant code this
can't be turned off.
static void wpas_start_assoc_cb(struct wpa_radio_work *work, int deinit)
{
[...]
if ((wpa_s->drv_flags & WPA_DRIVER_FLAGS_4WAY_HANDSHAKE_8021X) &&
(params.key_mgmt_suite == WPA_KEY_MGMT_IEEE8021X ||
params.key_mgmt_suite == WPA_KEY_MGMT_IEEE8021X_SHA256 ||
params.key_mgmt_suite == WPA_KEY_MGMT_IEEE8021X_SUITE_B ||
params.key_mgmt_suite == WPA_KEY_MGMT_IEEE8021X_SUITE_B_192))
params.req_handshake_offload = 1;
[...]
}
That means someone (and that's not me) needs to update our wifi plugin to work
with 2.9
The workaround is to use iwd for wifi.
Thanks,
Daniel

I have seen this problem before but I can't remember what is
exactly was. There was something about how the link loader
is looking up symbols. Sorry can't remember right now.
Thanks,
