Hi Jason, I'm not familiar with the crypto code. From wg_noise_init() it looks the init part is in header file. So I just disabled wireguard directly. For disabling the modules. Hi Ondrej, do you know if there is any FIPS policy in crypto part? There seems no handler when load not allowed crypto modules in FIPS mode. BTW, I also has a question, apart from the different RFC standard, what's the relation/difference between crypto/chacha20poly1305.c and lib/crypto/chacha20poly1305.c? Thanks Hangbin
