13 June 2017: Wouter
- Fix #1280: Unbound fails assert when response from authoritative
contains malformed qname. When 0x20 caps-for-id is enabled, when
assertions are not enabled the malformed qname is handled correctly.
- tag for 1.6.3
13 April 2017: Wouter
- Fix #1250: inconsistent indentation in services/listen_dnsport.c.
- tag for 1.6.2rc1
12 April 2017: Wouter
- subnet mem value is available in shm, also when not enabled,
to make the struct easier to memmap by other applications,
independent of the configuration of unbound.
12 April 2017: Ralph
- Fix #1247: unbound does not shorten source prefix length when
forwarding ECS.
- Properly check for allocation failure in local_data_find_tag_datas.
- Fix #1249: unbound doesn't return FORMERR to bogus ECS.
- Set SHM ECS memory usage to 0 when module not loaded.
11 April 2017: Ralph
- Display ECS module memory usage.
10 April 2017: Wouter
- harden-algo-downgrade: no also makes unbound more lenient about
digest algorithms in DS records.
10 April 2017: Ralph
- Remove ECS option after REFUSED answer.
- Fix small memory leak in edns_opt_copy_alloc.
- Respip dereference after NULL check.
- Zero initialize addrtree allocation.
- Use correct identifier for SHM destroy.
7 April 2017: George
- Fix pythonmod for cb changes.
- Some whitespace fixup.
7 April 2017: Ralph
- Unlock view in respip unit test
6 April 2017: Ralph
- Generalise inplace callback (de)registration
- (de)register inplace callbacks for module id
- No unbound-control set_option for ECS options
- Deprecated client-subnet-opcode config option
- Introduced client-subnet-always-forward config option

.B ip\-ratelimit\-factor: \fI<number>
Set the amount of queries to rate limit when the limit is exceeded.
If set to 0, all queries are dropped for addresses where the limit is
exceeded. If set to another value, 1 in that number is allowed through
to complete. Default is 10, allowing 1/10 traffic to flow normally.
This can make ordinary queries complete (if repeatedly queried for),
and enter the cache, whilst also mitigating the traffic flow by the
factor given.

.LP
If the destination address is whitelisted with Unbound will add the EDNS0 option
to the query containing the relevant part of the client's address. When an
answer contains the ECS option the response and the option are placed in a
specialized cache. If the authority indicated no support, the response is stored
in the regular cache.
.LP
Additionally, when a client includes the option in its queries, Unbound will
forward the option to the authority regardless of the authorities presence in
the whitelist. In this case the lookup in the regular cache is skipped.
.LP
The maximum size of the ECS cache is controlled by 'msg-cache-size' in the
configuration file. On top of that, for each query only 100 different subnets
are allowed to be stored for each address family. Exceeding that number, older
entries will be purged from cache.
.TP
.B send\-client\-subnet: \fI<IP address>\fR
Send client source address to this authority. Append /num to indicate a
classless delegation netblock, for example like 10.2.3.4/24 or 2001::11/64. Can
be given multiple times. Authorities not listed will not receive edns-subnet
information.
.TP
.B client\-subnet\-always\-forward: \fI<yes or no>\fR
Specify whether the ECS whitelist check (configured using
\fBsend\-client\-subnet\fR) is applied for all queries, even if the triggering
query contains an ECS record, or only for queries for which the ECS record is
generated using the querier address (and therefore did not contain ECS data in
the client query). If enabled, the whitelist check is skipped when the client
query contains an ECS record. Default is no.
.TP
.B max\-client\-subnet\-ipv6: \fI<number>\fR
Specifies the maximum prefix length of the client source address we are willing
to expose to third parties for IPv6. Defaults to 56.

Reverse DNS lookup involves determining the hostname associated with a given IP address.
Reverse DNS lookup involves determining the hostname associated with a given IP
address.
This example shows how reverse lookup can be done using unbound module.
For the reverse DNS records, the special domain in-addr.arpa is reserved.
For example, a host name for the IP address 74.125.43.147 can be obtained by issuing a DNS query for the PTR record for address 147.43.125.74.in-addr.arpa.
For example, a host name for the IP address ``74.125.43.147`` can be obtained

Introduction
===================================
============
**Unbound**
Unbound
-------
`Unbound`_ is an implementation of a DNS resolver, that performs caching and DNSSEC validation.
Together with unbound, the libunbound library is provided.
This library can be used to convert hostnames to ip addresses, and back, as well as obtain other information.
Since the resolver allows to specify the class and type of a query (A record, NS, MX, ...), this library offers powerful resolving tool.
The library also performs public-key validation of results with DNSSEC.

**pyUnbound**
.. _Unbound: http://www.unbound.net/documentation
The pyUnbound is an extension module for Python which provides an object-oriented interface to libunbound.
It is the first Python module which offers thread-safe caching resolver.
The interface was designed with the emphasis on the simplicity of use.
There are two main classes :class:`unbound.ub_ctx` (a validation and resolution context) and :class:`unbound.ub_result` which contains the validation and resolution results.
The objects are thread-safe, and a context can be used in non-threaded as well as threaded environment.
Resolution can be performed blocking and non-blocking (i.e. asynchronous).
The asynchronous method returns from the call immediately, so that processing can go on, while the results become available later.

**Features**
* customizable caching validation resolver for synchronous and asynchronous lookups
* easy to use object interface
* easy to integrate extension module
* designed for thread environment (i.e. thread-safe)
* allows define and customize of local zone and its RR's during the operation (i.e. without restart)
* includes encoding functions to simplify the results retrieval
* Internationalized domain name (`IDN`_) support

**Application area**
* DNS-based applications performing DNS lookups; the caching resolver can reduce overhead
* Applications where the validation of DNS records is required
* Great solution for customizable and dynamic DNS-based white/blacklists (spam rejection, connection rejection, ...) using the dynamic local zone manipulation

EDNS options
============
This example shows how to interact with EDNS options.
When quering unbound with the EDNS option ``65001`` and data ``0xc001`` we
expect an answer with the same EDNS option code and data ``0xdeadbeef``.
Key parts
~~~~~~~~~
This example relies on the following functionalities:
Registering EDNS options
------------------------
By registering EDNS options we can tune unbound's behavior when encountering a
query with a known EDNS option. The two available options are:
- ``bypass_cache_stage``: If set to ``True`` unbound will not try to answer
from cache. Instead execution is passed to the modules
- ``no_aggregation``: If set to ``True`` unbound will consider this query
unique and will not aggregate it with similar queries
Both values default to ``False``.
.. code-block:: python
if not register_edns_option(env, 65001, bypass_cache_stage=True,
no_aggregation=True):
log_info("python: Could not register EDNS option {}".format(65001))
EDNS option lists
-----------------
EDNS option lists can be found in the :class:`module_qstate` class. There are
four available lists in total:
- :class:`module_qstate.edns_opts_front_in`: options that came from the client
side. **Should not** be changed
- :class:`module_qstate.edns_opts_back_out`: options that will be sent to the
server side. Can be populated by edns literate modules
- :class:`module_qstate.edns_opts_back_in`: options that came from the server
side. **Should not** be changed
- :class:`module_qstate.edns_opts_front_out`: options that will be sent to the
client side. Can be populated by edns literate modules
Each list element has the following members:
- ``code``: the EDNS option code;
- ``data``: the EDNS option data.
Reading an EDNS option list
...........................
The lists' contents can be accessed in python by their ``_iter`` counterpart as
an iterator:
.. code-block:: python
if not edns_opt_list_is_empty(qstate.edns_opts_front_in):
for o in qstate.edns_opts_front_in_iter:
log_info("python: Code: {}, Data: '{}'".format(o.code,
"".join('{:02x}'.format(x) for x in o.data)))
Writing to an EDNS option list
..............................
By appending to an EDNS option list we can add new EDNS options. The new
element is going to be allocated in :class:`module_qstate.region`. The data
**must** be represented with a python ``bytearray``:
.. code-block:: python
b = bytearray.fromhex("deadbeef")
if not edns_opt_list_append(qstate.edns_opts_front_out,
o.code, b, qstate.region):
log_info("python: Could not append EDNS option {}".format(o.code))
We can also remove an EDNS option code from an EDNS option list.
.. code-block:: python
if not edns_opt_list_remove(edns_opt_list, code):
log_info("python: Option code {} was not found in the "
"list.".format(code))
.. note:: All occurences of the EDNS option code will be removed from the list:
Controlling other modules' cache behavior
-----------------------------------------
During the modules' operation, some modules may interact with the cache
(e.g., iterator). This behavior can be controlled by using the following
:class:`module_qstate` flags:
- :class:`module_qstate.no_cache_lookup`: Modules *operating after* this module
will not lookup the cache for an answer
- :class:`module_qstate.no_cache_store`: Modules *operating after* this module
will not store the response in the cache
Both values default to ``0``.
.. code-block:: python
def operate(id, event, qstate, qdata):
if (event == MODULE_EVENT_NEW) or (event == MODULE_EVENT_PASS):
# Detect if edns option code 56001 is present from the client side. If
# so turn on the flags for cache management.
if not edns_opt_list_is_empty(qstate.edns_opts_front_in):
log_info("python: searching for edns option code 65001 during NEW "
"or PASS event ")
for o in qstate.edns_opts_front_in_iter:
if o.code == 65001:
log_info("python: found edns option code 65001")
# Instruct other modules to not lookup for an
# answer in the cache.
qstate.no_cache_lookup = 1
log_info("python: enabled no_cache_lookup")
# Instruct other modules to not store the answer in
# the cache.
qstate.no_cache_store = 1
log_info("python: enabled no_cache_store")

Inplace callbacks
=================
This example shows how to register and use inplace callback functions. These
functions are going to be called just before unbound replies back to a client.
They can perform certain actions without interrupting unbound's execution flow
(e.g. add/remove EDNS options, manipulate the reply).
Two different scenarios will be shown:
- If answering from cache and the client used EDNS option code ``65002`` we
will answer with the same code but with data ``0xdeadbeef``;
- When answering with a SERVFAIL we also add an empty EDNS option code
``65003``.
Key parts
~~~~~~~~~
This example relies on the following functionalities:
Registering inplace callback functions
--------------------------------------

- `inplace callback reply functions`_
- `inplace callback reply_cache functions`_
- `inplace callback reply_local functions`_
- `inplace callback reply_servfail functions`_
Inplace callback reply functions
