It is possible for the GO of a persistent group to change the PSK or remove a client when per-client PSKs are used and this can happen without the SSID changing (i.e., the group is still valid, but just not for a specific client). If the client side of such persistent group ends up trying to use an invalidated persistent group information, the connection will fail in 4-way handshake. A new WPS provisioning step is needed to recover from this. Detect this type of case based on two 4-way handshake failures when acting as a P2P client in a persistent group. A new "P2P-PERSISTENT-PSK-FAIL id=<persistent group id>" event is used to indicate when this happens. This makes it easier for upper layers to remove the persistent group information with "REMOVE_NETWORK <persistent group id>" if desired (e.g., based on user confirmation). In addition to indicating the error cases for persistent groups, all this type of PSK failures end up in the client removing the group with the new reason=PSK_FAILURE information in the P2P-GROUP-REMOVED event.

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).
