FragAttacks: Fragmentation & Aggregation Attacks

wpa_bss_in_use() used to determine that a BSS with BSSID of 00:00:00:00:00:00 is in use in almost every case since either wpa_s->bssid or wpa_s->pending_bssid was likely to be cleared. This could result in a corner case of a BSS entry remaining in the BSS table indefinitely if one was added there with a (likely bogus) address of 00:00:00:00:00:00. Fix this by ignore wpa_s->bssid and wpa_s->pending_bssid if the BSSID in the BSS table entry is 00:00:00:00:00:00. In theory, that address is a valid BSSID, but it is unlikely to be used in any production AP, so the potential expiration of a BSS entry with that address during a connection attempt would not be a concern (especially when a new scan would be enough to recover from that).

wpa_supplicant and hostapd -------------------------- Copyright (c) 2002-2014, Jouni Malinen <j@w1.fi> and contributors All Rights Reserved. These programs are licensed under the BSD license (the one with advertisement clause removed). If you are submitting changes to the project, please see CONTRIBUTIONS file for more instructions. This package may include either wpa_supplicant, hostapd, or both. See README file respective subdirectories (wpa_supplicant/README or hostapd/README) for more details. Source code files were moved around in v0.6.x releases and compared to earlier releases, the programs are now built by first going to a subdirectory (wpa_supplicant or hostapd) and creating build configuration (.config) and running 'make' there (for Linux/BSD/cygwin builds).
