Patching Wilink 8.7 SP3 onto Sitara SDK 4 to fix WPA2 Issue

Part Number:WILINK8-WIFI-NLCP

Tool/software: Linux

Following the WL18 integration guide: WL18xx_Platform_Integration_Guide , The are build scripts for generating kernel modules, firmware, hostapd, and other tools.

The WPA2 issues post in this forum states that using wilink 8.7 SP3 will patch the vulnerabilities.

There are support posts on SDKv4 which state that the kernel modules (or 'modules' step in the build script) is not required in sdkv4 and Appendix A states that there is a single patch that updates three files in the SDKv4 kernel sources.

So to get Sitara SDKv4 patched with the latest Wilink 8.7SP3 package and no longer vulnerable to WPA2 key reinstallation attacks, is it enough to install firmware,utilities, and other software(leaving out the modules step) using the following commands using the build scripts and leave the .ko files generated by running the TI SDKv4 kernel build after applying the patch from Appendix A?:

1. build_wl18xx.sh init R8.7_SP3
2. build_wl18xx.sh libnl
3. build_wl18xx.sh hostapd
4. build_wl18xx.sh wpa_supplicant
5. build_wl18xx.sh firmware
6. build_wl18xx.sh utils
7. build_wl18xx.sh scripts
