Hi, I've tried using the aesni generic gcm(aes) aead to implement TLS SW fallback and I'm getting [ 3356.839506] BUG: sleeping function called from invalid context at ./include/crypto/algapi.h:417
The warning is coming from a ___might_sleep() macro that is called if CRYPTO_TFM_REQ_MAY_SLEEP is set. I'm getting the warning regardless of if pass CRYPTO_ALG_ASYNC or 0 as flags to crypto_alloc_aead("gcm(aes)", 0, flags). I've also noticed that rfc4106_encrypt() includes a irq_fpu_usable() check while generic_gcmaes_encrypt() doesn't. Is the generic gcm(aes) aead unsafe in atomic context? And if so which aead should I use? Finally, out of curiosity, doesn't macsec crypto run in atomic context? Thanks, Ilya
