Subject: Need help with failling gcm_base(ctr,ghash-generic) selftest
Date: Thu, 1 Aug 2019 21:42:49 +0200	[thread overview]
Message-ID: <20190801194249.GA18705@Red> (raw)

Hello

I am writing the Allwinner sun8i-ce driver and when running tcrypt I got
[   30.201739] alg: aead: gcm_base(ctr-aes-sun8i-ce,ghash-generic) decryption failed on test vector 3; expected_error=0, actual_error=-74, cfg=\"random: may_sleep use_digest src_divs=[100.0%@+2614] dst_divs=[5.90%@alignmask+3015, 60.56%@+3996, 17.92%@+865, 15.62%@+10]\"
or
[  148.613537] alg: aead: gcm_base(ctr-aes-sun8i-ce,ghash-generic) encryption test failed (wrong result) on test vector 2, cfg=\"random: may_sleep use_final src_divs=[100.0%@+0] iv_offset=20\"

Since ctr-aes-sun8i-ce is passing the ctr(aes) selftest, I dont understand what could be wrong.

Thanks
Regards
