Title:
  Remove incomplete fips in openssl in xenial.

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

Bug description:
  Package: openssl-1.0.2g-1ubuntu4.1
  Distro: xenial

  The openssl contains incomplete fips patches. In light that the fips
  is incomplete and will not be completed in the main archive and they
  are impacting customers, they should be withdrawn. See lp bugs
  1593953, 1591797, 1594748, 1588524, 1613658. Removal of these fips
  patches will remove these fips-related issues.

  [Test case]
  1. Problem in 1594748
  Note: this problem was reported in upstream openssl and testcase posted there also.
  https://rt.openssl.org/Ticket/Display.html?id=4559

  CRYPTO_set_mem_functions() always returns 0 because library
  initialization within fips code already calls CRYPTO_malloc() and
  disables it.

  This testcase should cause openssl to abort, but instead it returns a
  context.

  #include <stdio.h>
  #include <stdlib.h>
  #include <openssl/ssl.h>
  void * my_alloc(size_t n) { abort(); }
  void my_free(void *p) { abort(); }
  void * my_realloc(void *p, size_t n) { abort(); }
  int main(int argc, const char **argv)
  {
    const SSL_METHOD *method;
    SSL_CTX *ctx;
    CRYPTO_set_mem_functions(my_alloc, my_realloc, my_free);
    SSL_library_init();
    method = SSLv23_client_method();
    ctx = SSL_CTX_new(method);
    printf("Got ctx %p\n", ctx);
    return 0;
  }

  2. Problem in 1593953
  EC key generation allows user to generate keys using EC curves that the EC sign and verify
  do not support when OPENSSL_FIPS is defined.
  Testcase taken from lp #1593953

  openssl ecparam -genkey -name Oakley-EC2N-4

  will fail when OPENSSL_FIPS is defined since it causes a fips key-pair consistency check to be done.
  Otherwise, without OPENSSL_FIPS defined, the check is not done.

  3. Problem reported in 1588524
  Error code being skipped...

  Testcase taken from lp #1588524

  #include <openssl/err.h>
  #include <openssl/ssl.h>

  int main() {
      int rc;
      unsigned long fips_err;
      SSL_library_init();
      SSL_load_error_strings();
      ERR_load_crypto_strings();
      OpenSSL_add_all_algorithms();
      rc = FIPS_mode_set(1);
      fips_err = ERR_peek_last_error();

      // FIPS_mode_set will return 0 on failure, which is expected if
      // the FIPS module is not compiled. In this case, we should then
      // be able to get the error code
      // CRYPTO_R_FIPS_MODE_NOT_SUPPORTED (0xf06d065)
      // https://wiki.openssl.org/index.php/FIPS_mode_set%28%29
      printf("%d %lu\n", rc, fips_err);
      ERR_print_errors_fp(stdout);

      ERR_free_strings();
      return 0;
  }

  Should report an error message.

  [ Regression potential ]
  Removing the fips patches should decrease regression potential of openssl in the main archive.
