However, FullMac cards (that do -not generate netdev_associate_event) could still connect using FT AKMs -and perform the Initial mobility association. In such cases the FTE -element was required but ended up not being set into the handshake. -This caused the handshake to fail during PTK 1_of_4 processing. - -Fix this by making sure that FTE + related info is set into the -handshake, albeit with a lower sanity checking level since the -elements have been processed by the firmware already. - -Note that it is currently impossible for actual FTs to be performed on -FullMac cards, so the extra logic and sanity checking to handle these -can be skipped. ---- - src/netdev.c | 44 ++++++++++++++++++++++++++++++++++++++++++++ - 1 file changed, 44 insertions(+) - -diff --git a/src/netdev.c b/src/netdev.c -index b5c7be94..56fc67c9 100644 ---- a/src/netdev.c -+++ b/src/netdev.c -@@ -1753,6 +1753,8 @@ static void netdev_connect_event(struct l_genl_msg *msg, struct netdev *netdev) - const uint8_t *ies = NULL; - size_t ies_len = 0; - struct ie_tlv_iter iter; -+ const uint8_t *resp_ies = NULL; -+ size_t resp_ies_len; - - l_debug(""); - -@@ -1786,6 +1788,10 @@ static void netdev_connect_event(struct l_genl_msg *msg, struct netdev *netdev) - ies = data; - ies_len = len; - break; -+ case NL80211_ATTR_RESP_IE: -+ resp_ies = data; -+ resp_ies_len = len; -+ break; - } - } - -@@ -1834,6 +1840,44 @@ static void netdev_connect_event(struct l_genl_msg *msg, struct netdev *netdev) - } - } - -+ if (resp_ies) { -+ const uint8_t *fte = NULL; -+ struct ie_ft_info ft_info; -+ -+ ie_tlv_iter_init(&iter, resp_ies, resp_ies_len); -+ -+ while (ie_tlv_iter_next(&iter)) { -+ data = ie_tlv_iter_get_data(&iter); -+ -+ switch (ie_tlv_iter_get_tag(&iter)) { -+ case IE_TYPE_FAST_BSS_TRANSITION: -+ fte = data - 2; -+ break; -+ } -+ } -+ -+ if (fte) { -+ /* -+ * If we are here, then most likely we have a FullMac -+ * hw performing initial mobility association.
