+Subject: [PATCH] mesh: fix crash with CONFIG_TAXONOMY enabled
+
+wpa_s->ifmsh needs to be allocated using hostapd_alloc_iface() instead
+of a direct call to os_zalloc, otherwise the linked list for station
+taxonomy items remains uninitialized, leading to a crash on the first
+attempt to traverse that list
