Raw Blame History

From 69cd05bf635d19b9844f65d83dace05136a40326 Mon Sep 17 00:00:00 2001
From: Christian Heimes <cheimes@redhat.com>
Date: Fri, 19 Mar 2021 11:48:38 +0100
Subject: [PATCH] Add basic support for subordinate user/group ids
New LDAP object class "ipaUserSubordinate" with four new fields:
- ipasubuidnumber / ipasubuidcount
- ipasubgidnumber / ipasgbuidcount
New self-service permission to add subids.
New command user-auto-subid to auto-assign subid
The code hard-codes counts to 65536, sets subgid equal to subuid, and
does not allow removal of subids. There is also a hack that emulates a
DNA plugin with step interval 65536 for testing.
Work around problem with older SSSD clients that fail with unknown
idrange type "ipa-local-subid", see: https://github.com/SSSD/sssd/issues/5571

+# Central management of subordinate user and group ids
+
+Subordinate ids are a Linux Kernel feature to grant a user additional
+user and group id ranges. Amongst others the feature can be used
+by container runtime engies to implement rootless containers.
+Traditionally subordinate id ranges are configured in ``/etc/subuid``
+and ``/etc/subgid``.
+
+To make rootless containers in a large environment as easy as pie, IPA
+gains the ability to centrally manage and assign subordinate id ranges.
+SSSD and shadow-util are extended to read subordinate ids from IPA and
+provide them to userspace tools.

+
+## Design choices
+
+Some design choices are owed to the circumstance that uids and gids
+are limited datatypes. The Linux Kernel and userland defines
+``uid_t`` and ``gid_t`` as unsigned 32bit integers (``uint32_t``), which
+limits possible values for numeric user and group ids to
+``0 .. 2^32-2``. ``(uid_t)-1`` is reserved for error reporting. On the
+other hand the user ``nobody`` typically has uid 65534 / gid 65534. This
+means we need to assign 65,536 subordinate ids to every user. The
+theoretical maximum amount of subordinate ranges is less than 65,536
+(``65536 * 65536 == 2^32``). [``logins.def``](https://man7.org/linux/man-pages/man5/login.defs.5.html)
+also uses 65536 as default setting for ``SUB_UID_COUNT``.
+
+The practical limit is far smaller. Subordinate ids should not overlap
+with system accounts, local user accounts, IPA user accounts, and
+mapped accounts from Active Directory. Therefore IPA uses the upper
+half of the uid_t range (>= 2^31 == 2,147,483,648) for subordinate ids.
+The high bit is rarely used. IPA limits general numeric ids
+(``uidNumber``, ``gidNumber``, ID ranges) to maximum values of signed
+32bit integer (2^31-1) for backwards compatibility with XML-RPC.
+``logins.def`` defaults to ``SUB_UID_MAX`` 600,100,000.
+
+A default subordinate id count of 65,536 and a total range of approx.
+2.1 billion limits IPA to slightly more than 32,000 possible ranges. It
+may sound like a lot of users, but there are much bigger installations
+of IPA. For comparison Fedora Accounts has over 120,000 users stored in
+IPA.
+
+For that reason we treat subordinate id space as premium real estate
+and don't auto-map or auto-assign subordinate ids by default. Instead
+we give the admin several options to assign them manually, semi-manual,
+or automatically.
+
+### Revision 1 limitation
+
+The first revision of the feature is deliberately limited and
+restricted. We are aiming for a simple implementation that covers
+basic use cases. Some restrictions may be lifted in the future.
+
+* subuid and subgids cannot be set independently. They are always set
+ to the same value.
+* counts are hard-coded to value 65536
+* once assigned subids cannot be removed
+* IPA does not support multiple subordinate id ranges. Contrary to
+ ``/etc/subuid``, users are limited to one set of subordinate ids.
+* subids are auto-assigned. Auto-assignment is currently emulated
+ until 389-DS has been extended to support DNA with step interval.
+* subids are allocated from hard-coded range
+ ``[2147483648..4294901767]`` (``2^31`` to ``2^32-1-65536``), which
+ is the upper 2.1 billion uids of ``uid_t`` (``uint32_t``). The range
+ can hold little 32,767 subordinate id ranges.
+* Active Directory support is out of scope and may be provided in the
+ future.
+
+### Subid assignment example
+
+```
+>>> import itertools
+>>> def subids():
+... for n in itertools.count(start=0):
+... start = SUBID_RANGE_START + (n * SUBID_COUNT)
+... last = start + SUBID_COUNT - 1
+... yield (start, last)
+...
+>>> gen = subids()
+>>> next(gen)
+(2147483648, 2147549183)
+>>> next(gen)
+(2147549184, 2147614719)
+>>> next(gen)
+(2147614720, 2147680255)
+```
+
+The first user has 65565 subordinate ids from uid/gid ``2147483648``
+to ``2147549183``, the next user has ``2147549184`` to ``2147614719``,
+and so on. The range count includes the start value.
+
+An installation with multiple servers, 389-DS'
+[DNA](https://directory.fedoraproject.org/docs/389ds/design/dna-plugin.html)
+plug-in takes care of delegating and assigning chunks of subid ranges
+to servers. The DNA plug-in guarantees uniqueness across servers.
+
+## LDAP
+
+### LDAP schema extension
+
+The subordinate id feature introduces a new auxiliar object class
+``ipaSubordinateId`` with four required attributes ``ipaSubUidNumber``,
+``ipaSubUidCount``, ``ipaSubGidNumber``, and ``ipaSubGidCount``. The
+attributes with ``number`` suffix store the start value of the interval.
+The ``count`` attributes contain the size of the interval including the
+start value. The maximum subid is
+``ipaSubUidNumber + ipaSubUidCount - 1``.
+
+All four attributes are single-value ``INTEGER`` type with standard
+integer matching rules. OIDs ``2.16.840.1.113730.3.8.23.8`` and
+``2.16.840.1.113730.3.8.23.11`` are reserved for future use.

+
+The ``ipaSubordinateId`` object class is an auxiliar subclass of
+``top`` and requires all four subordinate id attributes as well as
+``uidNumber``. It does not subclass ``posixAccount`` to make
+the class reusable in idview overrides later.
+
+```raw
+objectClasses: (
+ 2.16.840.1.113730.3.8.24.4
+ NAME 'ipaSubordinateId'
+ DESC 'Subordinate uid and gid for users'
+ SUP top AUXILIARY
+ MUST ( uidNumber $ ipaSubUidNumber $ ipaSubUidCount $ ipaSubGidNumber $ ipaSubGidCount )
+ X-ORIGIN 'IPA v4.9'
+)
+```
+
+The ``ipaSubordinateGid`` and ``ipaSubordinateUid`` are defined for
+future use. IPA always assumes the presence of ``ipaSubordinateId`` and
+does not use these object classes.
+
+```raw
+objectClasses: (
+ 2.16.840.1.113730.3.8.24.2
+ NAME 'ipaSubordinateUid'
+ DESC 'Subordinate uids for users, see subuid(5)'

+ MUST ( uidNumber $ ipaSubGidNumber $ ipaSubGidCount )
+ X-ORIGIN 'IPA v4.9'
+)
+```
+
+### Index
+
+The attributes ``ipaSubUidNumber`` and ``ipaSubGidNumber`` are index
+for ``pres`` and ``eq`` with ``nsMatchingRule: integerOrderingMatch``
+to enable efficient ``=``, ``>=``, and ``<=`` searches.
+
+### Distributed numeric assignment (DNA) plug-in extension
+
+Subordinate id auto-assignment requires an extension of 389-DS'
+[DNA](https://directory.fedoraproject.org/docs/389ds/design/dna-plugin.html)
+plug-in. The DNA plug-in is responsible for safely assigning unique
+numeric ids across all replicas.
+
+Currently the DNA plug-in only supports a step size of ``1``. A new
+option ``dnaStepAttr`` (name is tentative) will tell the DNA plug-in
+to use the value of entry attributes as step size.
+
+
+## Permissions, Privileges, Roles
+
+### Self-servive RBAC
+
+The self-service permission enables users to request auto-assignment
+of subordinate uid and gid ranges for themselves. Subordinate ids cannot
+be modified or deleted.
+
+* ACI: *selfservice: Add subordinate id*
+* Permission: *Self-service subordinate ID*
+* Privilege: *Subordinate ID Selfservice User*
+* Role: *Subordinate ID Selfservice Users*
+* role default member: n/a
+
+### Administrator RBAC
+
+The administrator permission allows privileged users to auto-assign
+subordinate ids to users. Once assigned subordinate ids cannot
+be modified or deleted.
+
+* ACI: *Add subordinate ids to any user*
+* Permission: *Manage subordinate ID*
+* Privilege: *Subordinate ID Administrators*
+* default privilege role: *User Administrator*
+
+
+## Workflows
+
+In the default configuration of IPA, neither existing users nor new
+users will have subordinate ids assigned. There are a couple of ways
+to assign subordinate ids to users.
+
+### User administrator
+
+Users with *User Administrator* role and members of the *admins* group
+have permission to auto-assign new subordinate ids to any user. Auto
+assignment can be performed with new ``user-auto-subid`` command on the
+command line or with the *Auto assign subordinate ids* action in the
+*Actions* drop-down menu in the web UI.
+
+```shell
+$ ipa user-auto-subid someusername
+```
+
+### Self-service for group members
+
+Ordinary users cannot self-service subordinate ids by default. Admins
+can assign the new *Subordinate ID Selfservice User* to users group to
+enable self-service for members of the group.
+
+For example to enable self-service for all members of the default user
+group ``ipausers``, do:
+
+```shell
+$ ipa role-add-member "Subordinate ID Selfservice User" --groups=ipausers
+```
+
+This allows members of ``ipausers`` to request subordinate ids with
+the ``user-auto-subid`` command or the *Auto assign subordinate ids*
+action in the web UI.
+
+```shell
+$ ipa user-auto-subid myusername
+```
+
+### Auto assignment with user default object class
+
+Admins can also enable auto-assignment of subordinate ids for all new
+users by adding ``ipasubordinateid`` as a default user objectclass.
+This can be accomplished in the web UI under "IPA Server" /
+"Configuration" / "Default user objectclasses" or on the command line
+with:
+
+```shell
+$ ipa config-mod --addattr="ipaUserObjectClasses=ipasubordinateid"
+```
+
+**NOTE:** The objectclass must be written all lower case.
+
+### ipa-subid tool
+
+Finally IPA includes a new tool for mass-assignment of subordinate ids.
+The command uses automatic LDAPI EXTERNAL bind when it's executed as
+root user. Other it requires valid Kerberos TGT of an admin or user
+administrator.
+
+```raw
+
+# /usr/libexec/ipa/ipa-subids --help
+Usage: ipa-subids
+
+Mass-assign subordinate ids
+
+Options:
+ --version show program's version number and exit
+ -h, --help show this help message and exit
+ --group=GROUP Filter by group membership
+ --filter=USER_FILTER Raw LDAP filter
+ --dry-run Dry run mode.
+ --all-users All users
+
+ Logging and output options:
+ -v, --verbose print debugging information
+ -d, --debug alias for --verbose (deprecated)
+ -q, --quiet output only errors
+ --log-file=FILE log to the given file
+
+# # /usr/libexec/ipa/ipa-subids --group ipausers
+Processing user 'testsubordinated1' (1/15)
+Processing user 'testsubordinated2' (2/15)

+Processing user 'testsubordinated14' (14/15)
+Processing user 'testsubordinated15' (15/15)
+Processed 15 user(s)
+The ipa-subids command was successful
+```
+
+### Find and match users by any subordinate id
+
+The ``user-find`` command search by start value of subordinate uid and
+gid range. The new command ``user-match-subid`` can be used to find a
+user by any subordinate id in their range.
+
+```raw
+$ ipa user-match-subid --subuid=2153185287
+ User login: asmith
+ First name: Alice
+ Last name: Smith
+ ...
+ SubUID range start: 2153185280
+ SubUID range size: 65536
+ SubGID range start: 2153185280
+ SubGID range size: 65536
+----------------------------
+Number of entries returned 1
+----------------------------
+$ ipa user-match-subid --subuid=2153185279
+ User login: bjones
+ First name: Bob
+ Last name: Jones
+ ...
+ SubUID range start: 2153119744
+ SubUID range size: 65536
+ SubGID range start: 2153119744
+ SubGID range size: 65536
+----------------------------
+Number of entries returned 1
+----------------------------
+```
+
+## SSSD integration
+
+* base: ``cn=accounts,$SUFFIX`` / ``cn=users,cn=accounts,$SUFFIX``
+* scope: ``SCOPE_SUBTREE`` (2) / ``SCOPE_ONELEVEL`` (1)
+* user filter: should include ``(objectClass=posixAccount)``
+* attributes: ``uidNumber ipaSubUidNumber ipaSubUidCount ipaSubGidNumber ipaSubGidCount``
+
+SSSD can safely assume that only *user accounts* of type ``posixAccount``
+have subordinate ids. In the first revision there are no other entries
+with subordinate ids. The ``posixAccount`` object class has ``uid``
+(user login name) and ``uidNumber`` (numeric user id) as mandatory
+attributes. The ``uid`` attribute is guaranteed to be unique across
+all user accounts in an IPA domain.
+
+The ``uidNumber`` attribute is commonly unique, too. However it's
+technically possible that an administrator has assigned the same
+numeric user id to multiple users. Automatically assigned uid numbers
+don't conflict. SSSD should treat multiple users with same numeric
+user id as an error.
+
+The attribute ``ipaSubUidNumber`` is always accompanied by
+``ipaSubUidCount`` and ``ipaSubGidNumber`` is always accompanied
+by ``ipaSubGidCount``. In revision 1 the presence of
+``ipaSubUidNumber`` implies presence of the other three attributes.
+All four subordinate id attributes and ``uidNumber`` are single-value
+``INTEGER`` types. Any value outside of range of ``uint32_t`` must
+treated as invalid. SSSD will never see the DNA magic value ``-1``
+in ``cn=accounts,$SUFFIX`` subtree.
+
+IPA recommends that SSSD simply extends its existing query for user
+accounts and requests the four subordinate attributes additionally to
+RFC 2307 attributes ``rfc2307_user_map``. SSSD can directly take the
+values and return them without further processing, e.g.
+``uidNumber:ipaSubUidNumber:ipaSubUidCount`` for ``/etc/subuid``.
+
+Filters for additional cases:
+
+* subuid filter (find user with subuid by numeric uid):
+ ``&((objectClass=posixAccount)(ipaSubUidNumber=*)(uidNumber=$UID))``,
+ ``(&(objectClass=ipaSubordinateId)(uidNumber=$UID))``, or similar
+* subuid enumeration filter:
+ ``&((objectClass=posixAccount)(ipaSubUidNumber=*)(uidNumber=*))``,
+ ``(objectClass=ipaSubordinateId)``, or similar
+* subgid filter (find user with subgid by numeric uid):
+ ``&((objectClass=posixAccount)(ipaSubGidNumber=*)(uidNumber=$UID))``,
+ ``(&(objectClass=ipaSubordinateId)(uidNumber=$UID))``, or similar
+* subgid enumeration filter:
+ ``&((objectClass=posixAccount)(ipaSubGidNumber=*)(uidNumber=*))``,
+ ``(objectClass=ipaSubordinateId)``, or similar
+
+## Implementation details
+
+* The four subid attributes are not included in
+ ``baseuser.default_attributes`` on purpose. The ``config-mod``
+ command does not permit removal of a user default objectclasses
+ when the class is the last provider of an attribute in
+ ``default_attributes``.
+* ``ipaSubordinateId`` object class does not subclass the other two
+ object classes. LDAP supports
+ ``SUP ( ipaSubordinateGid $ ipaSubordinateUid )`` but 389-DS only
+ auto-inherits from first object class.
+* The idrange entry ``$REALM_subid_range`` has preconfigured base RIDs
+ and SID so idrange plug-in and sidgen task ignore the entry. It's the
+ simplest approach to ensure backwards compatibility with older IPA
+ server versions that don't know how to handle the new range.
+ The SID is ``S-1-5-21-738065-838566-$DOMAIN_HASH``. ``S-1-5-21``
+ is the well-known SID prefix for domain SIDs. ``738065-838566`` is
+ the decimal representation of the string ``IPA-SUB``. ``DOMAIN_HASH``
+ is the MURMUR-3 hash of the domain name for key ``0xdeadbeef``. SSSD
+ rejects SIDs unless they are prefixed with ``S-1-5-21`` (see
+ ``sss_idmap.c:is_domain_sid()``).
+* The new ``$REALM_subid_range`` entry uses range type ``ipa-ad-trust``
+ instead of range type ``ipa-local-subid`` for backwards compatibility
+ with older SSSD clients, see
+ [SSSD #5571](https://github.com/SSSD/sssd/issues/5571).
+* Shared DNA configuration entries in ``cn=dna,cn=ipa,cn=etc,$SUFFIX``
+ are automatically removed by existing code. Server and replication
+ plug-ins search and delete entries by ``dnaHostname`` attribute.
+
+### TODO
+
+* enable configuration for ``dnaStepAttr``
+* remove ``fake_dna_plugin`` hack from ``baseuser`` plug-in.
+* add custom range type for idranges and teach AD trust, sidgen, and
+ range overlap check code to deal with new range type.
