Fix output of dnsrecord_del: it now uses output.standard_delete
and excludes --all and --raw flags.
Fix output of sudorule_{add,remove}_option: they now use
output.standard_entry and include --all and --raw flags.

Extend DNS RR conflict check and forbid DNAME+NS combination unless
it is done in root DNS zone record.
Add tests to verify this enforced check.
https://fedorahosted.org/freeipa/ticket/3449
Refactor DNS RR conflict validator so that it is better extensible in
the future. Also check that there is only one CNAME defined for
a DNS record.
PTR+CNAME record combination is no longer allowed as we found out it
does not make sense to have this combination.
https://fedorahosted.org/freeipa/ticket/3450
Recent LDAP refactoring replaced entry_attrs regular dict with
normalized keys (i.e. lowercase) with LDAPEntry instance which keys
may not be normalized. This broke CND command output when
--structured and --all options were used.
Force lowercase normalization of the LDAPEntry keys in DNS plugin
structured format postprocessing. Also add a missing test for
DNS record structured output.
https://fedorahosted.org/freeipa/ticket/3526
Several Commands were missing the 'version' option. Add it to those
that were missing it.
Do not remove the version option before calling commands. This means
methods such as execute(), forward(), run() receive it.
Several of these needed `**options` added to their signatures.
Commands in the Cert plugin passed any unknown options to the underlying
functions, these are changed to pass what's needed explicitly.
Some commands in DNS and Batch plugins now pass version to commands
they call.
When the option is not given, fill it in automatically. (In a subsequent
commit, a warning will be added in this case).
Note that the public API did not change: all RPC calls already accepted
a version option. There's no need for an API version bump (even though
API.txt changes substantially).

bind-dyndb-ldap allows disabling global forwarder per-zone. This may
be useful in a scenario when we do not want requests to delegated
sub-zones (like sub.example.com. in zone example.com.) to be routed
through global forwarder.
Few lines to help added to explain the feature to users too.
https://fedorahosted.org/freeipa/ticket/3209
Nameserver hostname passed to dnszone_add command was always treated
as FQDN even though it was a relative DNS name to the new zone. All
relative names were being rejected as unresolvable.
Modify --name-server option processing in dnszone_add and dnszone_mod
to respect FQDN/relative DNS name and do the checks accordingly. With
this change, user can add a new zone "example.com" and let dnszone_add
to create NS record "ns" in it, when supplied with its IP address. IP
address check is more strict so that it is not entered when no forward
record is created. Places misusing the option were fixed.
Nameserver option now also accepts zone name, which means that NS and A
record is placed to DNS zone itself. Also "@" is accepted as a nameserver
name, BIND understand it also as a zone name. As a side-effect of this
change, other records with hostname part (MX, KX, NS, SRV) accept "@"
as valid hostname. BIND replaces it with respective zone name as well.
Unit tests were updated to test the new format.
https://fedorahosted.org/freeipa/ticket/3204
When DNS is being installed during ipa-{server,dns,replica}-install,
forward and reverse zone is created. However, reverse zone was always
created with default zonemgr even when a custom zonemgr was passed
to the installer as this functionality was missing in function
creating reverse zone.
Consolidate functions creating forward and reverse zones to avoid
code duplication and errors like this one. Reverse zones are now
created with custom zonemgr (when entered by user).
https://fedorahosted.org/freeipa/ticket/2790
When there were no updated attrs when modifying a nonexistent DNS record,
the error was not handled and caused an internal server error later (old_entry
was used uninitialized).
https://fedorahosted.org/freeipa/ticket/3055
When a new reverse zone is to be generated based on an IP address without
a network prefix length, we need to use some default value. While netaddr
library default ones (32b for IPv4 and 128b for IPv6) are not very sensible
we should use the defaults already applied in installers. That is 24b for
IPv6 and 64 for IPv6.
Test case has been added to cover the new default.
https://fedorahosted.org/freeipa/ticket/2461
Currently, we throw many public exceptions without proper i18n.
Wrap natural-language error messages in _() so they can be translated.
In the service plugin, raise NotFound errors using handle_not_found helper
so the error message contains the offending service.
Use ScriptError instead of NotFoundError in bindinstance install.
https://fedorahosted.org/freeipa/ticket/1953
Even though managedBy output parameter was only used for failed host
managedBy memberships, it was defined in global baseldap.py
classes. Incorrect label was then being displayed also for DNS zone
per-zone permission attribute with the same name.
Move managedBy output parameter to host plugin. Define proper managedBy
output parameter in DNS plugin to improve clarity of this attribute.
https://fedorahosted.org/freeipa/ticket/2946
* Convert every string specifying a DN into a DN object
* Every place a dn was manipulated in some fashion it was replaced by
the use of DN operators
* Add new DNParam parameter type for parameters which are DN's
* DN objects are used 100% of the time throughout the entire data
pipeline whenever something is logically a dn.
* Many classes now enforce DN usage for their attributes which are
dn's. This is implmented via ipautil.dn_attribute_property(). The
only permitted types for a class attribute specified to be a DN are
either None or a DN object.
* Require that every place a dn is used it must be a DN object.
This translates into lot of::
assert isinstance(dn, DN)
sprinkled through out the code. Maintaining these asserts is
valuable to preserve DN type enforcement. The asserts can be
disabled in production.
The goal of 100% DN usage 100% of the time has been realized, these
asserts are meant to preserve that.
The asserts also proved valuable in detecting functions which did
not obey their function signatures, such as the baseldap pre and
post callbacks.
* Moved ipalib.dn to ipapython.dn because DN class is shared with all
components, not just the server which uses ipalib.
* All API's now accept DN's natively, no need to convert to str (or
unicode).
* Removed ipalib.encoder and encode/decode decorators. Type conversion
is now explicitly performed in each IPASimpleLDAPObject method which
emulates a ldap.SimpleLDAPObject method.
* Entity & Entry classes now utilize DN's
* Removed __getattr__ in Entity & Entity clases. There were two
problems with it. It presented synthetic Python object attributes
based on the current LDAP data it contained. There is no way to
validate synthetic attributes using code checkers, you can't search
the code to find LDAP attribute accesses (because synthetic
attriutes look like Python attributes instead of LDAP data) and
error handling is circumscribed. Secondly __getattr__ was hiding
Python internal methods which broke class semantics.
* Replace use of methods inherited from ldap.SimpleLDAPObject via
IPAdmin class with IPAdmin methods. Directly using inherited methods
was causing us to bypass IPA logic. Mostly this meant replacing the
use of search_s() with getEntry() or getList(). Similarly direct
access of the LDAP data in classes using IPAdmin were replaced with
calls to getValue() or getValues().
* Objects returned by ldap2.find_entries() are now compatible with
either the python-ldap access methodology or the Entity/Entry access
methodology.
* All ldap operations now funnel through the common
IPASimpleLDAPObject giving us a single location where we interface
to python-ldap and perform conversions.
* The above 4 modifications means we've greatly reduced the
proliferation of multiple inconsistent ways to perform LDAP
operations. We are well on the way to having a single API in IPA for
doing LDAP (a long range goal).
* All certificate subject bases are now DN's
* DN objects were enhanced thusly:
- find, rfind, index, rindex, replace and insert methods were added
- AVA, RDN and DN classes were refactored in immutable and mutable
variants, the mutable variants are EditableAVA, EditableRDN and
EditableDN. By default we use the immutable variants preserving
important semantics. To edit a DN cast it to an EditableDN and
cast it back to DN when done editing. These issues are fully
described in other documentation.
- first_key_match was removed
- DN equalty comparison permits comparison to a basestring
* Fixed ldapupdate to work with DN's. This work included:
- Enhance test_updates.py to do more checking after applying
update. Add test for update_from_dict(). Convert code to use
unittest classes.
- Consolidated duplicate code.
- Moved code which should have been in the class into the class.
- Fix the handling of the 'deleteentry' update action. It's no longer
necessary to supply fake attributes to make it work. Detect case
where subsequent update applies a change to entry previously marked
for deletetion. General clean-up and simplification of the
'deleteentry' logic.
- Rewrote a couple of functions to be clearer and more Pythonic.
- Added documentation on the data structure being used.
- Simplfy the use of update_from_dict()
* Removed all usage of get_schema() which was being called prior to
accessing the .schema attribute of an object. If a class is using
internal lazy loading as an optimization it's not right to require
users of the interface to be aware of internal
optimization's. schema is now a property and when the schema
property is accessed it calls a private internal method to perform
the lazy loading.
* Added SchemaCache class to cache the schema's from individual
servers. This was done because of the observation we talk to
different LDAP servers, each of which may have it's own
schema. Previously we globally cached the schema from the first
server we connected to and returned that schema in all contexts. The
cache includes controls to invalidate it thus forcing a schema
refresh.
* Schema caching is now senstive to the run time context. During
install and upgrade the schema can change leading to errors due to
out-of-date cached schema. The schema cache is refreshed in these
contexts.
* We are aware of the LDAP syntax of all LDAP attributes. Every
attribute returned from an LDAP operation is passed through a
central table look-up based on it's LDAP syntax. The table key is
the LDAP syntax it's value is a Python callable that returns a
Python object matching the LDAP syntax. There are a handful of LDAP
attributes whose syntax is historically incorrect
(e.g. DistguishedNames that are defined as DirectoryStrings). The
table driven conversion mechanism is augmented with a table of
hard coded exceptions.
Currently only the following conversions occur via the table:
- dn's are converted to DN objects
- binary objects are converted to Python str objects (IPA
convention).
- everything else is converted to unicode using UTF-8 decoding (IPA
convention).
However, now that the table driven conversion mechanism is in place
it would be trivial to do things such as converting attributes
which have LDAP integer syntax into a Python integer, etc.
* Expected values in the unit tests which are a DN no longer need to
use lambda expressions to promote the returned value to a DN for
equality comparison. The return value is automatically promoted to
a DN. The lambda expressions have been removed making the code much
simpler and easier to read.
* Add class level logging to a number of classes which did not support
logging, less need for use of root_logger.
* Remove ipaserver/conn.py, it was unused.
* Consolidated duplicate code wherever it was found.
* Fixed many places that used string concatenation to form a new
string rather than string formatting operators. This is necessary
because string formatting converts it's arguments to a string prior
to building the result string. You can't concatenate a string and a
non-string.
* Simplify logic in rename_managed plugin. Use DN operators to edit
dn's.
* The live version of ipa-ldap-updater did not generate a log file.
The offline version did, now both do.

RFC 1912 states that no record (besides PTR) is allowed to coexist
with any other record type. When BIND detects this situation, it
refuses to load such records.
Enforce the constrain for dnsrecord-mod and dnsrecord-add commands.

SOA serial autoincrement is a requirement for major DNS features,
e.g. zone transfers or DNSSEC. Enable it by default in named.conf
both for new and upgraded installations. Name of the bind-dyndb-ldap
option is "serial_autoincrement".
From now on, idnsSOAserial attribute also has to be put to
replication agreement exclude list as serial will be incremented
on each DNS server separately and won't be shared. Exclude list
has to be updated both for new replication agreements and the
current ones.
Minimum number of connections for bind-dyndb-ldap has been rised
to 4 connections, the setting will be updated during package upgrade.
https://fedorahosted.org/freeipa/ticket/2554
IPA implements read/write permissions for DNS record or zones.
Provided set of permissions and privileges can, however, only grant
access to the whole DNS tree, which may not be appropriate.
Administrators may miss more fine-grained permissions allowing
them to delegate access per-zone.
Create a new IPA auxiliary objectclass ipaDNSZone allowing
a managedBy attribute for a DNS zone. This attribute will hold
a group DN (in this case a permission) which allows its members
to read or write in a zone. Member permissions in given zone
will only have 2 limitations:
1) Members cannot delete the zone
2) Members cannot edit managedBy attribute
Current DNS deny ACI used to enforce read access is removed so that
DNS privileges are based on allow ACIs only, which is much more
flexible approach as deny ACIs have always precedence and limit
other extensions. Per-zone access is allowed in 3 generic ACIs
placed in cn=dns,$SUFFIX so that no special ACIs has to be added
to DNS zones itselves.
2 new commands have been added which allows an administrator to
create the system permission allowing the per-zone access and
fill a zone's managedBy attribute:
* dnszone-add-permission: Add per-zone permission
* dnszone-remove-permission: Remove per-zone permission
https://fedorahosted.org/freeipa/ticket/2511
For security reasons, dynamic updates are not enabled for new DNS
zones. In order to enable the dynamic zone securely, user needs to
allow dynamic updates and create a zone update policy.
The policy is not easy to construct for regular users, we should
rather fill it by default and let users just switch the policy
on or off.
https://fedorahosted.org/freeipa/ticket/2441
Precallback validator was failing when a zone-relative name was
used as a NS record (for example record "ns" in a zone "example.com").
However, this is valid in BIND and we should allow it as well.
Imports in dns module had to be switched to absolute imports
(available from Python 2.5) to deal with a conflict of IPA dns
module and dnspython module.
https://fedorahosted.org/freeipa/ticket/2630
We actually perform two searches in permission-find. The first looks
for matches within the permission object itself. The second looks at
matches in the underlying aci.
We need to break out in two places. The first is if we find enough
matches in the permission itself. The second when we are appending
matches from acis.
The post_callback() definition needed to be modified to return
the truncated value so a plugin author can modify that value.
https://fedorahosted.org/freeipa/ticket/2322
IPA client and server tool set used authconfig acutil module to
for client DNS operations. This is not optimal DNS interface for
several reasons:
- does not provide native Python object oriented interface
but but rather C-like interface based on functions and
structures which is not easy to use and extend
- acutil is not meant to be used by third parties besides
authconfig and thus can break without notice
Replace the acutil with python-dns package which has a feature rich
interface for dealing with all different aspects of DNS including
DNSSEC. The main target of this patch is to replace all uses of
acutil DNS library with a use python-dns. In most cases, even
though the larger parts of the code are changed, the actual
functionality is changed only in the following cases:
- redundant DNS checks were removed from verify_fqdn function
in installutils to make the whole DNS check simpler and
less error-prone. Logging was improves for the remaining
checks
- improved logging for ipa-client-install DNS discovery

dnsrecord_add interactive mode did not work correctly when more
than one DNS record part was entered as command line option. It
asked for remaining options more than once. This patch fixes
this situation and also adds tests to cover this use case
properly.
https://fedorahosted.org/freeipa/ticket/2641
When dnsrecord-add or dnsrecord-mod commands are used on a root
zone record (it has a special name "@"), a zone name is returned
instead of a special name "@". This confuses DNS part of Web UI
which is then not able to manipulate records in the root zone
when these commands are used.
This patch fixes these 2 commands to return correct value when
a root zone is modified.
https://fedorahosted.org/freeipa/ticket/2627https://fedorahosted.org/freeipa/ticket/2628
Replace all occurences of create_default with equivalent default_from
and remove create_default from the framework. This is needed for
proper parameter validation, as there is no way to tell which
parameters to validate prior to calling create_default, because
create_default does not provide information about which parameters are
used for generating the default value.
Global DNS configuration is a nice tool to maintain a common DNS
settings stored in LDAP which are then used for all enrolled IPA
servers. However, the settings stored in LDAP override local
settings in named.conf on DNS servers.
This patch adds more information about global DNS configuration
options in install scripts and DNS module help.
https://fedorahosted.org/freeipa/ticket/2525
When dnsrecord-del pre_callback detects that the record does
not contain any records, it sets a flag to connection context
and deletes the record object later. However, when more
dnsrecord-del commands share the same context (and this is
the case of "ipa-replica-manage del $MASTER" DNS cleanup), it
may reuse a positive flag from previous dnsrecord-del command
and delete the root DNS zone record and thus effectively delete
the zone.
This patch makes sure that this flag is always initialized to a
sane value in dnsrecord-del pre_callback to make sure that the DNS
zone is not deleted. It also fixes pre_callback function definition
to prevent adding attrs_list to "keys" parameter and thus confuse
developers.
https://fedorahosted.org/freeipa/ticket/2503
There were cases where DNS plugin was too tolerant in a raw DNS
record option (--<rrtype-rec) processing. It let people specify
DNS record parts options in dnsrecord-mod operations for some
record without specifying the record that should be updated. It
also ignored DNS record parts in dnsrecord-add operation when the
raw DNS record value was already set via --<rrtype>-rec option.
This patch hardens the processing and returns error in both
described cases to make the processes clearer and more robust.
All these use cases were also covered by new unit tests.
https://fedorahosted.org/freeipa/ticket/2551
DNS plugin contains several RR type record validators run in
pre_callback which cannot be used as standard param validator
as it needs more data and resources that standard validators
provide. However, the precallback validators are not run for
DNS records created by new structured options and thus an invalid
value may slip in.
This patch moves the execution of these precallback validators
_after_ the processing of structured DNS options. It also cleans
them up a little and makes them more robust.
https://fedorahosted.org/freeipa/ticket/2550
Add a support for new global options in bind-dyndb-ldap, that is:
* idnsforwardpolicy: Default policy for conditional forwarding
* idnsallowsyncptr: Allow globaly PTR synchronization for dynamic
updates
* idnszonerefresh: Default interval between regular polls of the
name server for new DNS zones
https://fedorahosted.org/freeipa/ticket/2439
Let user enter custom ports for zone conditional forwarders or
global forwarders in dnsconfig. Ports can be specified in
a standard BIND format: IP_ADDRESS [port PORT]
https://fedorahosted.org/freeipa/ticket/2462
Add 2 new features to DNS record interactive help to increase its
usability and also make its behavior more consistent with standard
parameter interactive help:
1) Ask for missing DNS parts
When a required part of a newly added DNS record was missing, we
just returned a ValidationError. Now, the interactive help rather
asks for all missing required parts of all DNS records that were
being added by its parts.
2) Let user amend invalid part
When an interactive help asked for a DNS record part value and
user enters an invalid value, the entire interactive help exits
with an error. This may upset a user if he already entered several
correct DNS record part values. Now, the help rather tells user
what's wrong and give him an opportunity to amend the value.
https://fedorahosted.org/freeipa/ticket/2386
DNS Test Day shown that the new RR specific DNS options and the
concepts behind them may not be easily understood. This patch adds
an explanation of the new DNS framework for structured options
to make it easier for the user to understand and use the new
options.
https://fedorahosted.org/freeipa/ticket/2382
DNS and host plugin does not work well with domain names ending
with dot. host plugin creates a record with two fqdn attributes
when such hostname is created which then has to be manually fixed.
DNS plugin handled zones with and without trailing dot as two
distinct zones, which may lead to issues when both zones are
created.
This patch sanitizes approach to FQDNs in both DNS and host plugin.
Hostnames are now always normalized to the form without trailing
dot as this form did not work before and it would keep hostname
form consistent without changes in our server/client enrollment
process.
As DNS zones always worked in both forms this patch rather makes
sure that the plugin works with both forms of one zone and prevents
creating 2 identical zones with just different format.
https://fedorahosted.org/freeipa/ticket/2420
DNS plugin did not check DNS zone and DNS record validity and
user was thus able to create domains like "foo bar" or other
invalid DNS labels which would really confuse both user and
bind-dyndb-ldap plugin.
This patch at first consolidates hostname/domain name validators
so that they use common functions and we don't have regular
expressions and other checks defined in several places. These
new cleaned validators are then used for zone/record name
validation.
https://fedorahosted.org/freeipa/ticket/2384
When an invalid record type is entered during dnsrecord-add
interactive mode, user is provided with a list of allowed values
(record types). However, the provided list contains also
unsupported record types (APL, DHCID, etc.) and any attempt to add
such records would end with error. This patch limits the list
to supported record types only.
