FragAttacks: Fragmentation & Aggregation Attacks
cc1af6faed
Upon receiving FST setup request on old band, the peer is searched on new band. The assumption is that MB IE from this peer on new band previously received either in assoc event or in FST setup request. There are cases in which above assumption doesn't work, peer is not found and session setup fails. For example: - STA connects over 11ac. Due to driver limitation, MB IE is not included in assoc event - STA connects over 11ad. MB IE included in assoc event. - FST session established on 11ac band, with AP as initiator. i.e. FST setup request sent in AP=>STA direction. STA searches for peer's (AP) MB IE on 11ad band which exists. - FST switch occur - FST session established on 11ad band, with STA as initiator. i.e. FST setup request sent in STA=>AP direction. AP searches for peer's (STA) MB IE on 11ac band which are absent. For fixing the above, consider also peers without MB IE as candidates in the search algorithm.

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).
