[libvirt] [Patch v3 0/5] nwfilter: Support comment attribute in filter rule descriptions

V3: - moved MAX_COMMENT_LENGTH #define into include file (1/5) - renamed IPTABLES_MAX_COMMENT_SIZE to IPTABLES_MAX_COMMENT_LENGTH (2/5) - removal of regex from string patter in schema for comment attribute (3/5) - added libvirt version since when comment attribute is available (4/5) - added test cases (5/5) V2: - work on the iptables instantiation patch (2/5) - work on the parser patch (1/5) - small changes to the test cases (5/5) The following patch series adds support for a comment node to the XML attributes of all protocols. If possible, as for example in case of iptables, the comments are instantiated (iptables ... -m comment --comment ...). The patches do the following: - extend the parser and XML generator to parse and create XML with the comment attribute - instantiate the comment in case of ip(6)tables - extend the nwfilter.rng schema with the comment attribute - add the information to the web docs - add a test case for the XML parser/generator to be run during 'make check' Regards, Stefan
