FragAttacks: Fragmentation & Aggregation Attacks
f214361581
Do not start SAE authentication from scratch if a STA starts a new attempt for the same group while we still have previously generated PWE available. Instead, use the previously generated PWE as-is and skip anti-clogging token exchange since the heavy processing is already completed. This saves unnecessary processing on the AP side in case the STA failed to complete authentication on the first attempt (e.g., due to heavy SAE load on the AP causing a timeout) and makes it more likely for a valid STA to be able to complete SAE authentication during a DoS attack.

wpa_supplicant and hostapd -------------------------- Copyright (c) 2002-2019, 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).
