Wireless access point daemon, patched with ubus support
07a7bcd7ea
In theory, each device that supports WMM (or the IEEE 802.11 QoS for that matter) is expected to advertise how many replay counters it supports and the peer device is supposed to use that information to restrict the total number of different MSDU priorities (AC/UP) that might be used. In practice, this is not really done in deployed devices and instead, it is just assumed that everyone supports the eight different replay counters so that there is no need to restrict which MSDU priorities can be used. hostapd implementation of WMM has advertised support for 16 PTKSA replay counters from the beginning while wpa_supplicant has not had any code for setting the supported replay counter fields in RSNE, i.e., has left the value to 0 which implies that only a single replay counter is supported. While this does not really result in any real issues with deployed devices, this is not really correct behavior based on the current IEEE 802.11 standard and the WMM specification. Update wpa_supplicant to use similar design to the hostapd RSNE generation by setting the number of supported PTKSA replay counters to 16 whenever WMM is enabled. For now, this is done based on the association being for HT/VHT/HE/EHT and also based on the AP supporting WMM since it is much more likely for the local device to support WMM and eight replay counters (which can be indicated only with the value that implies support for 16 counters since there is no separate value for 8).

wpa_supplicant and hostapd -------------------------- Copyright (c) 2002-2022, 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).
