Bug #10229: RFC 5649 implementation in OpenSSL breaks Ruby.

* Author: Vit Ondruch

* Priority: Normal

----------------------------------------
Recently updated OpenSSL in Fedora 21+ [1] introduces support for RFC 5649 [2, 3]. However, this breaks Ruby's test suite:

~~~
  4) Error:
OpenSSL::TestCipher#test_ciphers:
OpenSSL::Cipher::CipherError: wrap mode not allowed
    /builddir/build/BUILD/ruby-2.2.0-r47525/test/openssl/test_cipher.rb:107:in `initialize'
    /builddir/build/BUILD/ruby-2.2.0-r47525/test/openssl/test_cipher.rb:107:in `new'
    /builddir/build/BUILD/ruby-2.2.0-r47525/test/openssl/test_cipher.rb:107:in `block in test_ciphers'
    /builddir/build/BUILD/ruby-2.2.0-r47525/test/openssl/test_cipher.rb:105:in `each'
    /builddir/build/BUILD/ruby-2.2.0-r47525/test/openssl/test_cipher.rb:105:in `test_ciphers'
~~~

I've been suggested by OpenSSL maintainer, that I should ignore the wrap ciphers, so I am going to use this patch for the moment:

~~~

       OpenSSL::Cipher.ciphers.each{|name|
         next if /netbsd/ =~ RUBY_PLATFORM && /idea|rc5/i =~ name
+        next if /wrap/ =~ name
         assert(OpenSSL::Cipher::Cipher.new(name).is_a?(OpenSSL::Cipher::Cipher))
       }
     end
~~~

but I'd like see this resolved correctly.
