Many DNS related tests involve wire format test +data, so it will be convenient if we can define the data in a more +intuitive way than writing the entire hex sequence by hand. + +Here is a simple example. Consider the following spec file: + + [custom] + sections: a + [a] + as_rr: True + +When the script reads this file, it detects the file specifies a single +component (called "section" here) that consists of a single A RDATA, +which must be dumped as an RR (not only the part of RDATA).

For +testing purposes many of these will be the same common one (like +"example.com" or 192.0.2.1), so it would be convenient if we only have +to specify non default parameters. To change the RDATA (i.e., the +IPv4 address), we should add the following line at the end of the spec +file: + + address: 192.0.2.2 + +Then the last two lines of the output file will be as follows: + + # Address=192.0.2.2 + c0000202 + +In some cases we would rather specify malformed data for tests. This +script has the ability to specify broken parameters for many types of +data. For example, we can generate data that would look like an A RR +but the RDLEN is 3 by adding the following line to the spec file: + + rdlen: 3 + +Then the first two lines of the output file will be as follows: + + # A RR (QNAME=example.com Class=IN(1) TTL=86400 RDLEN=3) + 076578616d706c6503636f6d00 0001 0001 00015180 0003 + +** USAGE ** + + gen_wiredata.py [-o output_file] spec_file + +If the -o option is missing, and if the spec_file has a suffix (such as +in the form of "data.spec"), the output file name will be the prefix +part of it (as in "data"); if -o is missing and the spec_file does not +have a suffix, the script will fail. + +** SPEC FILE SYNTAX ** + +A spec file accepted in this script should be in the form of a +configuration file that is parsable by the Python's standard +configparser module. In short, it consists of sections; each section +is identified in the form of [section_name] followed by "name: value" +entries. Lines beginning with # or ; will be treated as comments. +Refer to the configparser module documentation for further details of +the general syntax. + +This script has two major modes: the custom mode and the DNS query +mode. The former generates an arbitrary combination of DNS message +header, question section, RDATAs or RRs. It is mainly intended to +generate a test data for a single type of RDATA or RR, or for +complicated complete DNS messages. The DNS query mode is actually a +special case of the custom mode, which is a shortcut to generate a +simple DNS query message (with or without EDNS). + +* Custom mode syntax * + +By default this script assumes the DNS query mode. To specify the +custom mode, there must be a special "custom" section in the spec +file, which should contain 'sections' entry. This value of this +entryis colon-separated string fields, each of which is either +"header", "question", "edns", "name", or a string specifying an RR +type. For RR types the string is lower-cased string mnemonic that +identifies the type: 'a' for type A, 'ns' for type NS, and so on +(note: in the current implementation it's case sensitive, and must be +lower cased). + +Each of these fields is interpreted as a section name of the spec +(configuration), and in that section parameters specific to the +semantics of the field can be configured. + +A "header" section specifies the content of a DNS message header. +See the documentation of the DNSHeader class of this module for +configurable parameters. + +A "question" section specifies the content of a single question that +is normally to be placed in the Question section of a DNS message. +See the documentation of the DNSQuestion class of this module for +configurable parameters. + +An "edns" section specifies the content of an EDNS OPT RR. See the +documentation of the EDNS class of this module for configurable +parameters. + +A "name" section specifies a domain name with or without compression. +This is specifically intended to be used for testing name related +functionalities and would rarely be used with other sections. See the +documentation of the Name class of this module for configurable +parameters. + +In a specific section for an RR or RDATA, possible entries depend on +the type. But there are some common configurable entries. See the +description of the RR class. The most important one would be "as_rr". +It controls whether the entry should be treated as an RR (with name, +type, class and TTL) or only as an RDATA. By default as_rr is +"False", so if an entry is to be interpreted as an RR, an as_rr entry +must be explicitly specified with a value of "True". + +Another common entry is "rdlen". It specifies the RDLEN field value +of the RR (note: this is included when the entry is interpreted as +RDATA, too). By default this value is automatically determined by the +RR type and (it has a variable length) from other fields of RDATA, but +as shown in the above example, it can be explicitly set, possibly to a +bogus value for testing against invalid data. + +For type specific entries (and their defaults when provided), see the +documentation of the corresponding Python class defined in this +module. In general, there should be a class named the same mnemonic +of the corresponding RR type for each supported type, and they are a +subclass of the RR class. For example, the "NS" class is defined for +RR type NS. + +Look again at the A RR example shown at the beginning of this +description. There's a "custom" section, which consists of a +"sections" entry whose value is a single "a", which means the data to +be generated is an A RR or RDATA. There's a corresponding "a" +section, which only specifies that it should be interpreted as an RR +(all field values of the RR are derived from the default). + +If you want to generate a data sequence for two ore more RRs or +RDATAs, you can specify them in the form of colon-separated fields for +the "sections" entry. For example, to generate a sequence of A and NS +RRs in that order, the "custom" section would be something like this: + + [custom] + sections: a:ns + +and there must be an "ns" section in addition to "a". + +If a sequence of two or more RRs/RDATAs of the same RR type should be +generated, these should be uniquely indexed with the "/" separator. +For example, to generate two A RRs, the "custom" section would be as +follows: + + [custom] + sections: a/1:a/2 + +and there must be "a/1" and "a/2" sections. + +Another practical example that would be used for many tests is to +generate data for a complete DNS response message. The spec file of +such an example configuration would look like as follows: + + [custom] + sections: header:question:a + [header] + qr: 1 + ancount: 1 + [question] + [a] + as_rr: True + +With this configuration, this script will generate test data for a DNS +response to a query for example.com/IN/A containing one corresponding +A RR in the answer section. + +* DNS query mode syntax * + +If the spec file does not contain a "custom" section (that has a +"sections" entry), this script assumes the DNS query mode. This mode +is actually a special case of custom mode; it implicitly assumes the +"sections" entry whose value is "header:question:edns". + +In this mode it is expected that the spec file also contains at least +a "header" and "question" sections, and optionally an "edns" section. +But the script does not warn or fail even if the expected sections are +missing. + +* Entry value types * + +As described above, a section of the spec file accepts entries +specific to the semantics of the section. They generally correspond +to DNS message or RR fields. + +Many of them are expected to be integral values, for which either decimal or +hexadecimal representation is accepted, for example: + + rr_ttl: 3600 + tag: 0x1234 + +Some others are expected to be string. A string value does not have +to be quoted: + + address: 192.0.2.2 + +but can also be quoted with single quotes: + + address: '192.0.2.2' + +Note 1: a string that can be interpreted as an integer must be quoted. +For example, if you want to set a "string" entry to "3600", it should +be: + + string: '3600' + +instead of + + string: 3600 + +Note 2: a string enclosed with double quotes is not accepted: + + # This doesn't work: + address: "192.0.2.2" + +In general, string values are converted to hexadecimal sequences +according to the semantics of the entry. For instance, a textual IPv4 +address in the above example will be converted to a hexadecimal +sequence corresponding to a 4-byte integer. So, in many cases, the +acceptable syntax for a particular string entry value should be +obvious from the context. There are still some exceptional cases +especially for complicated RR field values, for which the +corresponding class documentation should be referenced. + +One special string syntax that would be worth noting is domain names, +which would naturally be used in many kinds of entries. The simplest +form of acceptable syntax is a textual representation of domain names +such as "example.com" (note: names are always assumed to be +"absolute", so the trailing dot can be omitted). But a domain name in +the wire format can also contain a compression pointer. This script +provides a simple support for name compression with a special notation +of "ptr=nn" where nn is the numeric pointer value (decimal). For example, +if the NSDNAME field of an NS RDATA is specified as follows: + + nsname: ns.ptr=12 + +this script will generate the following output: + + # NS name=ns.ptr=12 + 026e73c00c + +** EXTEND THE SCRIPT ** + +This script is expected to be extended as we add more support for +various types of RR. It is encouraged to add support for a new type +of RR to this script as we see the need for testing that type. Here +is a simple instruction of how to do that. + +Assume you are adding support for "FOO" RR. Also assume that the FOO +RDATA contains a single field named "value". + +What you are expected to do is as follows: + +- Define a new class named "FOO" inherited from the RR class. Also + define a class variable named "value" for the FOO RDATA field (the + variable name can be different from the field name, but it's + convenient if it can be easily identifiable.) with an appropriate + default value (if possible): + + class FOO(RR): + value = 10 + + The name of the variable will be (automatically) used as the + corresponding entry name in the spec file. So, a spec file that + sets this field to 20 would look like this: + + [foo] + value: 20 + +- Define the "dump()" method for class FOO. It must call + self.dump_header() (which is derived from class RR) at the + beginning. It then prints the RDATA field values in an appropriate + way. Assuming the value is a 16-bit integer field, a complete + dump() method would look like this: + + def dump(self, f): + if self.rdlen is None: + self.rdlen = 2 + self.dump_header(f, self.rdlen) + f.write('# Value=%d\\n' % (self.value)) + f.write('%04x\\n' % (self.value)) + + The first f.write() call is not mandatory, but is encouraged to + be provided so that the generated files will be more human readable. + Depending on the complexity of the RDATA fields, the dump() + implementation would be more complicated. In particular, if the + RDATA length is variable and the RDLEN field value is not specified + in the spec file, the dump() method is normally expected to + calculate the correct length and pass it to dump_header(). See the + implementation of various derived classes of class RR for actual + examples. +""" + +import configparser, re, time, socket, sys, base64 +from datetime import datetime +from optparse import OptionParser + +re_hex = re.compile(r'^0x[0-9a-fA-F]+') +re_decimal = re.compile(r'^\d+$') +re_string = re.compile(r"\'(.*)\'$") + +dnssec_timefmt = '%Y%m%d%H%M%S' + +dict_qr = { 'query' : 0, 'response' : 1 } +dict_opcode = { 'query' : 0, 'iquery' : 1, 'status' : 2, 'notify' : 4, + 'update' : 5 } +rdict_opcode = dict([(dict_opcode[k], k.upper()) for k in dict_opcode.keys()]) +dict_rcode = { 'noerror' : 0, 'formerr' : 1, 'servfail' : 2, 'nxdomain' : 3, + 'notimp' : 4, 'refused' : 5, 'yxdomain' : 6, 'yxrrset' : 7, + 'nxrrset' : 8, 'notauth' : 9, 'notzone' : 10 } +rdict_rcode = dict([(dict_rcode[k], k.upper()) for k in dict_rcode.keys()]) +dict_rrtype = { 'none' : 0, 'a' : 1, 'ns' : 2, 'md' : 3, 'mf' : 4, 'cname' : 5, + 'soa' : 6, 'mb' : 7, 'mg' : 8, 'mr' : 9, 'null' : 10, + 'wks' : 11, 'ptr' : 12, 'hinfo' : 13, 'minfo' : 14, 'mx' : 15, + 'txt' : 16, 'rp' : 17, 'afsdb' : 18, 'x25' : 19, 'isdn' : 20, + 'rt' : 21, 'nsap' : 22, 'nsap_tr' : 23, 'sig' : 24, 'key' : 25, + 'px' : 26, 'gpos' : 27, 'aaaa' : 28, 'loc' : 29, 'nxt' : 30, + 'srv' : 33, 'naptr' : 35, 'kx' : 36, 'cert' : 37, 'a6' : 38, + 'dname' : 39, 'opt' : 41, 'apl' : 42, 'ds' : 43, 'sshfp' : 44, + 'ipseckey' : 45, 'rrsig' : 46, 'nsec' : 47, 'dnskey' : 48, + 'dhcid' : 49, 'nsec3' : 50, 'nsec3param' : 51, 'tlsa' : 52, 'hip' : 55, + 'spf' : 99, 'unspec' : 103, 'tkey' : 249, 'tsig' : 250, + 'dlv' : 32769, 'ixfr' : 251, 'axfr' : 252, 'mailb' : 253, + 'maila' : 254, 'any' : 255, 'caa' : 257 } +rdict_rrtype = dict([(dict_rrtype[k], k.upper()) for k in dict_rrtype.keys()]) +dict_rrclass = { 'in' : 1, 'ch' : 3, 'hs' : 4, 'any' : 255 } +rdict_rrclass = dict([(dict_rrclass[k], k.upper()) for k in \ + dict_rrclass.keys()]) +dict_algorithm = { 'rsamd5' : 1, 'dh' : 2, 'dsa' : 3, 'ecc' : 4, + 'rsasha1' : 5 } +dict_nsec3_algorithm = { 'reserved' : 0, 'sha1' : 1 } +rdict_algorithm = dict([(dict_algorithm[k], k.upper()) for k in \ + dict_algorithm.keys()]) +rdict_nsec3_algorithm = dict([(dict_nsec3_algorithm[k], k.upper()) for k in \ + dict_nsec3_algorithm.keys()]) + +header_xtables = { 'qr' : dict_qr, 'opcode' : dict_opcode, + 'rcode' : dict_rcode } +question_xtables = { 'rrtype' : dict_rrtype, 'rrclass' : dict_rrclass } + +def parse_value(value, xtable = {}): + if re.search(re_hex, value): + return int(value, 16) + if re.search(re_decimal, value): + return int(value) + m = re.match(re_string, value) + if m: + return m.group(1) + lovalue = value.lower() + if lovalue in xtable: + return xtable[lovalue] + return value + +def code_totext(code, dict): + if code in dict.keys(): + return dict[code] + '(' + str(code) + ')' + return str(code) + +def encode_name(name, absolute=True): + # make sure the name is dot-terminated. duplicate dots will be ignored + # below. + name += '.' + labels = name.split('.') + wire = '' + for l in labels: + if len(l) > 4 and l[0:4] == 'ptr=': + # special meta-syntax for compression pointer + wire += '%04x' % (0xc000 | int(l[4:])) + break + if absolute or len(l) > 0: + wire += '%02x' % len(l) + wire += ''.join(['%02x' % ord(ch) for ch in l]) + if len(l) == 0: + break + return wire + +def encode_string(name, len=None): + if type(name) is int and len is not None: + return '%0.*x' % (len * 2, name) + return ''.join(['%02x' % ord(ch) for ch in name]) + +def encode_bytes(name, len=None): + if type(name) is int and len is not None: + return '%0.*x' % (len * 2, name) + return ''.join(['%02x' % ch for ch in name]) + +def count_namelabels(name): + if name == '.': # special case + return 0 + m = re.match('^(.*)\.$', name) + if m: + name = m.group(1) + return len(name.split('.')) + +def get_config(config, section, configobj, xtables = {}): + try: + for field in config.options(section): + value = config.get(section, field) + if field in xtables.keys(): + xtable = xtables[field] + else: + xtable = {} + configobj.__dict__[field] = parse_value(value, xtable) + except configparser.NoSectionError: + return False + return True + +def print_header(f, input_file): + f.write('''### +### This data file was auto-generated from ''' + input_file + ''' +### +''') + +class Name: + '''Implements rendering a single domain name in the test data format. + + Configurable parameter is as follows (see the description of the + same name of attribute for the default value): + -
