Title:
  EC_KEY_generate_key() causes FIPS self-test failure

Status in openssl package in Ubuntu:
  Fix Released
Status in openssl source package in Xenial:
  Fix Released

Bug description:
  EC_KEY_generate_key() internally calls fips_pkey_signature_test()
  which performs a pairwise check by ECDSA signing/verifying, but some
  groups don't support ECDSA.

  For example, `openssl ecparam -genkey -name Oakley-EC2N-4` fails.
  Unfortunately `openssl ecparam` doesn't give any useful information so
  I modified a bit:

  ~~~
  diff --git a/apps/ecparam.c b/apps/ecparam.c
  index 71b67f4..db89c2f 100644
  --- a/apps/ecparam.c
  +++ b/apps/ecparam.c
  @@ -585,6 +585,7 @@ int MAIN(int argc, char **argv)
   
           if (!EC_KEY_generate_key(eckey)) {
               EC_KEY_free(eckey);
  +            ERR_print_errors(bio_err);
               goto end;
           }
           if (outformat == FORMAT_ASN1)
  ~~~

  And I got:
