Except for a few older distros, Travis complains:

 openssl dgst  -sm3 sm3-hash.txt
+ evmctl -v  ima_hash --hashalgo sm3 --xattr-user sm3-hash.txt
  hash(sm3):
04111ab21d8355cfa17f8e61194831e81a8f22bec8c728fefb747ed035eb5082aa2b
Did not find expected hash for sm3:
    user.ima=0x011ab21d8355cfa17f8e61194831e81a8f22bec8c728fefb747ed035
eb5082aa2b
Actual output below:
    # file: sm3-hash.txt
    user.ima=0x04111ab21d8355cfa17f8e61194831e81a8f22bec8c728fefb747ed0

I'm also seeing:
- openssl req -verbose -new -nodes -utf8 -days 10000 -batch -x509 -sm3
-sigopt distid:1234567812345678 -config test-ca.conf -copy_extensions
copyall -newkey sm2 -out test-sm2.cer -outform DER -keyout test-sm2.key
req: Unrecognized flag copy_extensions

thanks,
