Zephyr hostap builds with CONFIG_FIPS, which strips HMAC-MD5 and RC4 call sites even when the PSA backend provides them. WPA-PSK (WPA1) APs require EAPOL-Key descriptor version 1: HMAC-MD5 for the 4-way MIC and RC4 for group-key unwrap. That breaks association with legacy and QuickTrack WPA-PSK test APs. When CONFIG_PSA_WANT_ALG_MD5 is set (personal STA crypto backends that explicitly enable legacy TKIP interop), allow the ver=1 MIC and RC4 key data paths. Builds without PSA MD5 keep the existing FIPS blocks. Signed-off-by: Chaitanya Tata <Chaitanya.Tata@nordicsemi.no> Assisted-by: Cursor:Auto

Closing this as fix is now purely contained in the Zephyr hostap module shim (zephyrproject-rtos/zephyr#111137) |
