Feature Truncation for Nameserver
fixes rt.cpan.org #33547 and #42744
TAKE CARE:
this feature may cause unexpected behavior for your nameservers
and can be turned off by setting Truncate to 0 during the creation
of the nameserver.
my $ns = Net::DNS::Nameserver->new(
Truncate => 0,
);
Net::DNS::Packet::truncate is a new method that is called from
within Net::DNS::Nameserver that truncates a packet according to
the rules of RFC2181 section 9.
Acknowledgement Aaron Crane for an elegant test and for
inspiration for a direction.
Feature: Added Net::DNS::Domain
Net::DNS::Domain is an attempt to introduce a consistent model
for representation of RFC 1035 s.
The class and its test script t/02-domain.t are included to be
exposed to various architectures.
The class and its methods may be subject to change, both in terms of

The implementation is trivial since the KX inherits almost all of
its functionality by inheritance from the MX RR.
Fix NSAP RR string representation
RFC1706 specifies the masterfile format to have a leading "0x" and

NOTE rt.cpan.org # 40249
Release 0.62 introduced a feature to parse data inside a packet only
when needed. This can cause the following to happen:
Exception: corrupt or incomplete data at
/usr/lib/perl5/Net/DNS/RR.pm line 510.
caught at -e line 1
This may happen when you have undefined your packet data before all the
sections have been fully parsed. Such as in:
$packet = Net::DNS::Packet->new(\$data);
undef($data);
The workaround is to force parsing by calling the methods that
parse the data. e.g.
$packet = Net::DNS::Packet->new(\$data);
$packet->answer; $packet->additional; $packet->authority;
undef ($data)
Fix rt.cpan.org # 41076 and # 41071
Net::DNS::RR->new_from_hash function would not normalize the content

Feature (rt.cpan.org #39284)
The ReplyHandler now also receives a variable with an anonymous hash with the connection details. Variables
supplied to the Reply handler are: $qname, $qclass, $qtype, $peerhost, $query, $conn
The hash referenced by $conn contains the following buckets: sockhost, sockport, peerhost, and peerport.
Feature t/08-online.t and t/10-recurse.t
In particular environments a query for a.t. will resolve and or
middleboxes will replace DNS packet content for queries to the root.
A bunch of test is skipped when this (broken) environment is
detected.
Feature/Bug rt.cpan.org #22019
The initial fix for rt 22019 was to strip a trailing dot from all
attributes that were provided as argument for the
Net::DNS::RR::new_from_hash function. We have introduced
Net::DNS::stripdot, a function that will strip the dots of domain
names, taking into account possible escapes (e.g. labels like
foo\\\..). As a side effect the new_from_string method will now
convert possible spaces that are not trapped by some of the
new_from_string functions and convert them to \032 escapes.
For information: The internal storage of domain names is using
presentation format without trailing dots.
Bug
@EXPORT and @EXPORT_OK moved to a BEGIN block so that Net::DNS::SEC
can make use of exported functions
Feature/Bug
The Notify handler introduced in 0.63 did not set the OPCODE on the
reply appropriately. This has been solved generically by allowing the
"Headermask" that is returned as 4th element by the reply or notify
handler in the nameserver also allows for the opcode to be set.
e.g. as in return ("NXDOMAIN",[],[],[],{ opcode => "NS_NOTIFY_OP" }
);
*** 0.63, 8 Feb 2008
This version contains a Security Fix.
Feature NotifyHandler in Nameserver
The NotifyHandler is a new attribute to the nameserver used in the
same way as the ReplyHandler except that it is executed when the
opcode is NS_NOTIFY (RFC1996). It takes the same arguments as the
reply handler (i.e. $qname, $qclass, $qtype, $peerhost, and $query).
Corrections made in the documentation.

Net/DNS/RR/A.pm in Net::DNS 0.60 build 654 allows remote attackers
to cause a denial of service (program "croak") via a crafted DNS
response (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2007-6341). Packet
parsing routines are now enclosed in eval blocks to trap exception
and avoid premature termination of user program.
Bug: mbox-dname and txt-dname were not allowed to be empty in the RP RR.
Fix by Peter Koch
*** 0.62, 28 December 2007
Features: Move of some functionality out of the Packet to the Question
and RR classes; parsing of elements in the packet is now performed
by calling the appropriate subclasses.
New methods were introduced:
* Net::DNS::Packet->parse()
* Net::DNS::RR->parse()
* Net::DNS::Question->parse()
The Packet class now defers parsing of authority/additional until
their content is really needed. This should cause a bit of
performance improvement.
Dick Franks is acknowledged for this Good Work (TM).
Added 20081216 see NOTE above under rt.cpan.org # 40249
Feature: the Net::DNS::Packet's answersize() method will from now on
ignore its arguments and just return the size of the packet.
Feature: The Net::DNS::RR->new() method used to call
Net::DNS::RR->new_from_data() whenever called with the appropriate
combination of arguments. That (undocumented) behavior has been deprecated.
Use Net::DNS::RR->new_from_data() directly if you depended on that.
Feature: Net::DNS::Packets unique_push now ignores the TTL in
comparison of uniqueness, this is closer to the intent of
RFC2181, but not yet fully compliant.

Feature check_soa test of NCACHE TTL
Dick Franks supplied an improved version of check_soa script which
performs a direct test of NCACHE TTL by looking up non-existent name and
reporting value if it exceeds 86400. Test is skipped unless minimumTTL is
above same threshold. Recent BIND implementations impose a ceiling on
NCACHE TTLs internally, so a large minimumTTL value is unlikely to have
damaging consequences at many sites.

Fix rt.cpan.org #24631 / Feature IP address prefix notation
Dick Franks supplied a cleaned up version of Question.pm.
Revised code deals with incomplete IPv6 address bug and accepts RFC4291
address prefix notation. IPv4/prefix also supported for completeness.
This involved a minor change to the API for reverse IP lookup. Changing
qtype to PTR is now performed for A and AAAA only. This allows queries
for NS and SOA records at interior nodes to be specified using the address
prefix. Type ANY queries now also produce the expected result.
Cleaned up TYPE/CLASS reversal code, exploiting fact that the intersection
of the sets of class and type names contains only one member (ANY).
Minor cleanup of remaining code.
Fix rt.cpan.org #22019
Expunge trailing dots from RR->new_from_hash() FQDN arguments.

Feature SSHFP warn instead of die
We do not die if a not implemented fingerprint type value is read
from the wire, instead we 'warn' and return undef.
Feature NSEC3PARAM hook
A hook to load NSEC3PARAM when available has been added.
WARNING: Both NSEC3 and NSEC3PARAM are configured with their
experimental type codes.
Feature rt r24525
Net::DNS::Resolver depended on Net::IP (2268 Kb) which depends on
heavy module Math::BigInt (1780 Kb). Valery Studennikov suggested to
ship Net::DNS::Resolver::Base with its own copies of ip_is_ipv[4|6] and
supplied a patch with those functions stripped from Net::IP.
Note that the package still depends on Net::IP because
Net::DNS::Nameserver and a few tests depend on it.

Fix rt.cpan.org 20836, 20857, 20994, and 21402
These tickets all revolved around proper reverse mapping of IPv6
addresses.
Acknowledgments to Dick Franks who has provided elegant solutions and
cleaned a bit of code.
Note that directly calling Question->new() without arguments will
cause the qclass,qtype to be IN, A instead of ANY, ANY.
Net::DNS::Resolver's search() method would always gracefully
interpret a qname in the form of an IPv4 address. It would go out
and do a PTR query in the reverse address tree. This behavior has
also been applied to IPv6 addresses in their many shapes and
forms.
This change did two things, 1) root zone not implicitly added to
search list when looking up short name, 2) default domain appended
to short name if DEFNAMES and not DNSRCH.
Fix rt.cpan.org 18113
Minor error due to unapplied part of patch fixed.

Net::DNS::typesbyval() now confesses on undefined

Feature Implemented SPF (typecode 99).
The class completely inherits from Net::DNS::RR::TXT (the easiest
RR to implement ever).
Feature added rrsort() function.
Feature was requested by Eric Hall in rt.cpan.org 13392
This was a little tricky as I think that the sort functions are in
fact RR specific class attributes that should be accessed through
class methods. This is difficult to implement. I do think I found a
fairly clean manner. It does require a global variable in Net::DNS
to store the functions and some trickery when the sorting functions
are defined.
See Net::DNS and Net::DNS::RR documentation for details.
Defaults sorting functions are currently implemented in
SRV: default sort: low priority to high priority and for
same preference highest weight first.
weight: sort all RRs based on weight, highest first
priority: see default sort
MX: default sort: lowest preference first.

TCP fallback after V6 socket failure
Reworked Net::DNS::Base::Nameserver::send_tcp() to fallback to IPv4 when
possible. (change applied to SVN Revision 538).
Feature Cleanup duplicated code
axfr_send() and send_tcp() contained some duplicated code. I merged
this in one "helper" method _create_tcp_socket()
Fix AXFR persistent sockets colliding with query sockets.
I think that using the same persistent sockets for AXFR and
'ordinary' queries could lead to race conditions. Better safe than
sorry. For axfrs we create a different set of persistent sockets.
Note that this prevents performing a SOA query first and then using
the same socket for the zone transfer itself(in Net::DNS these are
different code paths). This behavior of SOA and transfer on the
same socket-- seems to be suggested by 1035 section 4.2.2:
"In particular, the server should allow the SOA and AXFR request
sequence (which begins a refresh operation) to be made on a
single connection."
Obviously, on the client side this behavior is not mandatory.
Fix rt.cpan.org 17596
The fixes and features above also fixed the timeout problem reported by
Paul Hoffman
Profiling
It turned out that each time we were calling
Net::DNS::Resolver::Base::nameserver(); We were creating a

Using Net-DNS 0.53 on Win XP, it is unable to retrieve the
nameservers when the IP address of the interface is assigned by

problem. Applied the patch submitted by "orjan".

Fix rt.cpan.org 14046
RRSIGs verify and create failed for a number of RR types. The
error message showed something like:
Can't call method "dn_comp" on an undefined value
This was caused by an omission in the _canonicalRdata() method
in Net::DNS::RR that was inherited by all failing RR types.
Code was added to t/05-rr.t that will test signature creation
if Net::DNS::SEC is available and can be loaded.
Feature async nameserver behaviour.
In rt.cpan.org 14622 Robert Stone suggested:
The fact that it needs to take over the main running thread
limits its audience. Since many daemon programs are already
driven by a top level select loop, it seems useful to provide an
API for the user to integrate Net::DNS::Nameserver processing to
their own select loop.
He also supplied example code for which he is hereby acknowledged.
The patch was not used because simultaneously Robert Martin-Legène
supplied a patch to Nameservers.pm that allowed the same async
functionality through the use of loop_once method. Robert M-L's
code also carefully manages the TCP sockets, so that they can
deal with AXFRs.
Robert S. has been so kind to review Robert M-L's code and is hereby
kindly acknowledged.
NB. Since the code may be subject to change the documentation of the
loop_once method has been commented out.

Fixed a problem with persistent TCP sockets which was introduced
because of using the address family as an index to the array of

Used AF_UNSPEC for the array index for the TCP socket; just to choose
a number. The key to the persistent sockets is the remote nameserver:port
combination.

The escaped characters test failed on some system because the

Fix rt.cpan.org 13239:
When queries are refused the resolver would not take the next
nameserver on the nameserver list for its next try but skip one.
I was also made aware that the "use byte" pragma is incompatible
with pre 5.06 perl.
BEGIN {
eval { require bytes; }
}
It should be noted that for perl versions < 5.006 I had to disable
the escaped character test. Don't expect domain names with labels
that contain anything else than host names to work for versions
earlier than perl 5.6.0.

Fix:
Concatenation of scalars caused modification of data because of
Perl's habit to treat scalars as utf characters instead of bytes.
Inserted use bytes pragma throughout the code base. DNS is done
in octets.
Feature:
Added "ignqrid" as an attribute to the Resolver.
use as:
ok (my $res=Net::DNS::Resolver->new(nameservers => ['127.0.0.1'],
port => 5354,
recurse => 0,
igntc => 1,
ignqrid => 1,
),
When the attribute is set to a non-zero value replies with the
qr bit clear and replies with non-matching query ids are
happily accepted. This opens the possibility to accept spoofed
answers. YOU CAN BURN YOURSELF WITH THIS FEATURE.
It is set to 0 per default and remains, except for this changes file
an undocumented feature.
*** 0.49_02 May 28, 2005 (Version 0.50 release candidate 2)
Fix: Smoking Gun tests for non-cygwin Win32.
Makefile.PL failed to produce a proper Makefile under win32.
(e.g. www,nntp.perl.org/group/perl.cpan.testers/210570)
I worked around that by moving the library into the base
directory of the distribution as the "subdir" section
seemed to be all funny.
Fix: rt.cpan.org#11931 (the off-topic part)
Sidney Markowitz spotted an awkward condition that rarely happens but is
significant enough to be dealt with.
In the send_udp method there are two loops: one over the nameservers
and one that waits for the sockets to come forward with data.
That second loop will sometimes timeout and then be entered with a
repeated query to the same nameserver. It occasionally happens that the
old packet arrives on the socket. That packet is discarded but the
loop does not return to the loop to wait for the remainder of the
timeout period for an answer on the second query, that may still arrive.
This has now been fixed.
Thanks to Sidney for the assessment of the problem and the fix.
*** 0.49_01 (Version 0.50 release candidate 1)
Fix: Makefile.PL: Minor tweak to recognize Mac OS X 10.4 not so relevant
since netdnslib is distributed with the code.
Feature: Calling the Net::DNS::Resolver::dnssec method with a non-zero
argument will set the udppacketsize to 2048. The method will
also carp a warning if you pass a non-zero argument when
Net::DNS::SEC is not installed.
Feature: IPv6 transport support
IPv6 transport has been added to the resolver and to the
nameserver code.
To use IPv6 please make sure that you have IO::Socket::INET6 version
2.01 or later installed.
If IPv6 transport is available Net::DNS::Resolver::Recurse will make
use of it (picking randomly between IPv4 and IPv6 transport) use
the force_v4() method to only force IPv4.
Feature: Binary characters in labels
RFC 1035 3.1:
Domain names in messages are expressed in terms of a sequence of
labels. Each label is represented as a one octet length field
followed by that number of octets. Since every domain name ends
with the null label of the root, a domain name is terminated by a
length byte of zero. The high order two bits of every length octet
must be zero, and the remaining six bits of the length field limit
the label to 63 octets or less.
Unfortunately dname attributes are stored strings throughout
Net::DNS. (With hindsight dnames should have had their own class
in which one could have preserved the wire format.).
To be able to represent all octets that are allowed in domain
names I took the approach to use the "presentation format" for
the attributes. This presentation format is defined in RFC 1035
5.1.
I added code to parse presentation format domain names that has
escaped data such as \ddd and \X (where X is not a number) to
wireformat and vice verse. In the conversion from wire format to
presentation format the characters that have special meaning in a
zone file are escaped (so that they can be cut-n-pasted without
pain).
These are " (0x22), $ (0x24), (0x28), ) (0x29), . (0x2e) , ;
(0x3b), @ (ox40) and \ (0x5c). The number between brackets
representing the ascii code in hex.
Note that wherever a name occurs as a string in Net::DNS it is
now in presentation format.
For those that dealt with 'hostnames' (subset of all possible
domain names) this will be a completely transparent change.
Details:
I added netdnslib which contains Net::DNS's own dn_expand. Its
implemented in C and the source is a hodgepodge of Berkeley based
code and snippets from ISC's bind9 distribution. The behavior, in
terms of which chars are escaped, is similar to bind9.
There are some functions added to DNS.pm that do conversion from
presentation and wire format and back. They should only be used
internally (although they live in EXPORT_OK.)
For esoteric test cases see t/11-escapedchars.t.

Incorrect searchlist duplication removal in Net::DNS::Resolver::Win32
Patch courtesy Risto Kankkunen.
Problem: rt.cpan.org #11931
Win32.pm used the DNSRegisteredAdapters registry key to determine which
local forwarders to send queries to. This is arguably the wrong key as it
is used to identify the server which to send dynamic updates to.
A real fix for determining the set of nameservers to query has not been
implemented. For details see

that responded with an RCODE.
The errorstring will be set to "RCODE: "
Fix: rt.cpan.org #8803
TXT records don't work with semicolons
Since we are expecting "zonefile" presentation at input
a comment will need to be escaped ( \; ).
It could be argued that this is a to strict interpretation of
1035 section 5.1.
While working on this I discovered there are more problems with
TXT RRs. Eg; 0100 is a perfectly legal character string that
should be represented as "\000" in a zonefile. Net::DNS does
pass character strings with "non-ASCII" chars from the wire
to the char_str_lst array but the print functions do not
properly escape them when printing.
Properly dealing with zonefile presentation format and binary
data is still to be done.

Reply handlers in Net::DNS::Nameserver are now passed the query object.
Fixed a nasty bug in Nameserver.pm related to the qr bit. As Olaf
explained:
Replies are sent if the query has its "qr" bit set. The "qr" bit is an
indication that the packet is sent as a response to a query. Since
there are more implementations that suffer from this bug one can cause
all kinds of nasty ping-pong loops by spoofing the initial packet or
have an infinite query loop by spoofing a query from the localhost:53

the tests off.
Cleaned up Makefile.PL a little. The "--pm" flag is now deprecated, use
"--no-xs" instead.
Added support for unknown RR types (rfc3597). Note for developers: the
typesbyname, typesbyval, classesbyname and classesbyval hashes should
not be used directly, use the same named wrapper functions

Options to Net::DNS::Resolver->new() are now supported, including
using your own configuration file. See the Net::DNS::Resolver man
page for details.
Tweaked Net::DNS::RR::TXT to fail more gracefully when the quotes
in the data section are not balanced.
Add more tests (of course).
Moved next_id() from Resolver.pm to Header.pm (which is where it is
used).
Net::DNS::Select now uses $^O directly, this means that the second
argument to Net::DNS::Select::new() (the OS) is now ignored.
*** 0.38 Jun 5 2003
Various buglets fixed in the new Makefile.PL.
Use Dynaloader instead of XSLoader. Turns out that XSLoader is only
