 - Linux kernel: x86 accelerated implementations of xts, chacha20, gcm(aes), rfc4106(gcm(aes)), rfc7539(chacha20,poly1305), rfc7539esp(chacha20,poly1305) do not pass the extended/full kernel self tests. The issue is that the the test harness creates SGLs which are not aligned to cra_blocksize. Thus I am not sure whether the test harness is broken or whether leancrypto should handle such very strange (and not real-life scenarios).
