[ext/openssl] Encoding of subclasses fails when it shouldn't

Added by MartinBosslet (Martin Bosslet) about 13 years ago. Updated almost 13 years ago.

Description

=begin
While skimming through ossl_asn1.c I noticed that my patch for infinite length encoding
causes problems when encoding subclasses of OpenSSL::ASN1::Sequence or OpenSSL::ASN1::Set
with infinite length.

E.g. the following fails in trunk:

require 'openssl'

sub = Class.new(OpenSSL::ASN1::Sequence)
instance = sub.new([OpenSSL::ASN1::EndOfContent.new])
instance.infinite_length = true
puts instance.to_der

=> test.rb:10:in to_der': invalid constructed encoding (OpenSSL::ASN1::ASN1Error) from test.rb:10:in '

This can be fixed with the appended code that checks for subclass relationship instead
of comparing the class directly with Set or Sequence.

Regards,
Martin
