[sssd PR#529][comment] SPEC: Move secrets responder to the package sssd-kcm
by jhrozek 12 Mar '18

12 Mar '18

URL: https://github.com/SSSD/sssd/pull/529 Title: #529: SPEC: Move secrets responder to the package sssd-kcm jhrozek commented: """ I understand the point about minimal dependencies of sssd-common, but I wonder if it was better to create a separate subpackage for the secrets binary. This is for two reasons, a) the proposed packaging is not intuitive, b) we are actually thinking about not talking to the secrets REST API from KCM to secrets, but writing to the secrets database directly. And then bundling the two responders together wouldn't make sense. """ See the full comment at https://github.com/SSSD/sssd/pull/529#issuecomment-372444317

Announcing SSSD 1.16.1
by Jakub Hrozek 12 Mar '18

12 Mar '18

SSSD 1.16.1 =========== The SSSD team is proud to announce the release of version 1.16.1 of the System Security Services Daemon. The tarball can be downloaded from https://releases.pagure.org/SSSD/sssd/ RPM packages will be made available for Fedora shortly. Feedback -------- Please provide comments, bugs and other feedback via the sssd-devel or sssd-users mailing lists: https://lists.fedorahosted.org/mailman/listinfo/sssd-devel https://lists.fedorahosted.org/mailman/listinfo/sssd-users Highlights ————— New Features ^^^^^^^^^^^^ * A new option ``auto_private_groups`` was added. If this option is enabled, SSSD will automatically create user private groups based on user's UID number. The GID number is ignored in this case. Please see https://docs.pagure.org/SSSD.sssd/design_pages/auto_private_groups.html for more details on the feature. * The SSSD smart card integration now supports a special type of PAM conversation implemented by GDM which allows the user to select the appropriate smrt card certificate in GDM. Please refer to https://docs.pagure.org/SSSD.sssd/design_pages/smartcard_multiple_certifica… for more details about this feature. * A new API for accessing user and group information was added. This API is similar to the tradiional Name Service Switch API, but allows the consumer to talk to SSSD directly as well as to fine-tune the query with e.g. how cache should be evaluated. Please see https://docs.pagure.org/SSSD.sssd/design_pages/enhanced_nss_api.html for more information on the new API. * The ``sssctl`` command line tool gained a new command ``access-report``, which can generate who can access the client machine. Currently only generating the report on an IPA client based on HBAC rules is supported. Please see https://docs.pagure.org/SSSD.sssd/design_pages/attestation_report.html for more information about this new feature. * The ``hostid`` provider was moved from the IPA specific code to the generic LDAP code. This allows SSH host keys to be access by the generic LDAP provider as well. See the ``ldap_host_*`` options in the ``sssd-ldap`` manual page for more details. * Setting the ``memcache_timeout`` option to 0 disabled creating the memory cache files altogether. This can be useful in cases there is a bug in the memory cache that needs working around. Performance enhancements ^^^^^^^^^^^^^^^^^^^^^^^^ * Several internal changes to how objects are stored in the cache improve SSSD performance in environments with large number of objects of the same type (e.g. many users, many groups). In particular, several useless indexes were removed and the most common object types no longer use the indexed ``objectClass`` attribute, but use unindexed ``objectCategory`` instead (#3503) * In setups with ``id_provider=ad`` that use POSIX attributes which are replicated to the Global Catalog, SSSD uses the Global Catalog to determine which domain should be contacted for a by-ID lookup instead of iterating over all domains. More details about this feature can be found at https://docs.pagure.org/SSSD.sssd/design_pages/uid_negative_global_catalog.… Notable bug fixes ^^^^^^^^^^^^^^^^^ * A crash in ``sssd_nss`` that might have happened if a list of domains was refreshed while a NSS lookup using this request was fixed (#3551) * A potential crash in ``sssd_nss`` during netgroup lookup in case the netgroup object kept in memory was already freed (#3523) * Fixed a potential crash of ``sssd_be`` with two concurrent sudo refreshes in case one of them failed (#3562) * A memory growth issue in ``sssd_nss`` that occured when an entry was removed from the memory cache was fixed (#3588) * Two potential memory growth issues in the ``sssd_be`` process that could have hit configurations with ``id_provider=ad`` were fixed (#3639) * The ``selinux_child`` process no longer crashes on a system where SSSD is compiled with SELinux support, but at the same time, the SELinux policy is not even installed on the machine (#3618) * The memory cache consistency detection logic was fixed. This would prevent printing false positive memory cache corruption messages (#3571) * SSSD now remembers the last successfuly discovered AD site and use this for DNS search to lookup a site and forest during the next lookup. This prevents time outs in case SSSD was discovering the site using the global list of DCs where some of the global DCs might be unreachable. (#3265) * SSSD no longer starts the implicit file domain when configured with ``id_provider=proxy`` and ``proxy_lib_name=files``. This bug prevented SSSD from being used in setups that combine identities from UNIX files together with authentication against a remote source unless a files domain was explicitly configured (#3590) * The IPA provider can handle switching between different ID views better (#3579) * Previously, the IPA provider kept SSH public keys and certificates from an ID view in its cache and returned them even if the public key or certificate was then removed from the override (#3602, #3603) * FleetCommander profiles coming from IPA are applied even if they are assigned globally (to ``category: ALL``), previously, only profiles assigned to a host or a hostgroup were applied (#3449) * It is now possible to reset an expired password for users with 2FA authentication enabled (#3585) * A bug in the AD provider which could have resulted in built-in AD groups being incorrectly cached was fixed (#3610) * The SSSD watchdog can now cope better with time drifts (#3285) * The ``nss_sss`` NSS module's return codes for invalid cases were fixed * A bug in the LDAP provider that prevented setups with id_provider=proxy and auth_provider=ldap with LDAP servers that do not allow anonymous binds from working was fixed (#3451) Packaging Changes ----------------- * The FleetCommander desktop profile path now uses stricter permissions, 751 instead of 755 (#3621) * A new option ``--logger`` was added to the ``sssd(8)`` binary. This option obsoletes old options such as ``--debug-to-files``, although the old options are kept for backwards compatibility. * The file ``/etc/systemd/system/sssd.service.d/journal.conf`` is not installed anymore In order to change logging to journald, please use the ``--logger`` option. The logger is set using the ``Environment=DEBUG_LOGGER`` directive in the systemd unit files. The default value is ``Environment=DEBUG_LOGGER=--logger=files`` Documentation Changes --------------------- There are no notable documentation changes such as options changing default values etc in this release.

Github labels: Suggestion
by Fabiano Fidêncio 12 Mar '18

12 Mar '18

People, I've noticed that I'm getting a little bit lost with github and the way SSSD has its tags organized there. As it may actually affect other people (and in case it does not, let's just skip the following suggestion) ... I'd like to suggest the following tags to the project: - Accepted: We already have it; - Rejected: We already have it. - Tests needed: This one can either replace the "Changes Requested" (in case it's split in a few different tags) or be used together ... but the idea is to identify that tests are missing from a PR without going through the whole discussions happening there; - Depends on (or something similar): This one can either replace the "Changes Requested" (in case it's split in a few different tags) or be used together ... but the idea is to identify that we depend on somework that still has to be done (either another PR, ticket or something else that has to be implemented). Mind that I'm not sure whether we'd be able to simply add a field saying what the PR depends on ... - Postponed/Deferred: We have something similar for 2.0, but would be nice to have a way to clearly see in which release we're going to take a look into a specific PR without having to dig in the discussions. Here we could also have 1.16.1, 1.16.2, 2.0, ... - Reworked: Although just removing the "Changes Requested" label is fine, maybe having a tag explicitly saying that something was Reworked would be a clean way to differentiate between new PRs and PRs which have been through a review already ... Does the suggestion make sense? In case we have an agreement about this topic, may I re-tag our PRs and start using those new tags from new PRs? Best Regards, -- Fabiano Fidêncio

[sssd PR#527][opened] PEP8 Fixes and enable PEP8 check in CI
by mzidek-rh 10 Mar '18

10 Mar '18

Here is link to the ticket: https://pagure.io/SSSD/sssd/issue/3605 What I did: - reviewed all the patches that were not reviewed yet (some were already reviewed) - rebased them on top of current master (there were only minor conflicts) - if there are some missing patches that is because the issue that they fixed was no longer present in the current master, so I deleted them - added "Resolves" and "Reviewed" tags (so the person that pushes it does not need to add them) - pushed the patchset to CI (passed) - added pep8 issue and tried the CI (issue was detected on all platforms) The patchest is now fully ACKed. Note: because of the way I rebased the patches, some are not in the original order """ To pull the PR as Git branch: git remote add ghsssd https://github.com/SSSD/sssd git fetch ghsssd pull/527/head:pr527 git checkout pr527

This is not in agreement with man innetgr which says "Any of the elements in a triple can be empty, which means that anything matches. The functions described here allow access to the netgroup databases". This patch instead returns an empty domain as well, which eventually produces the same output as if the netgroup was requested from the compat tree.

RFC: 1.16.1 release notes
by Jakub Hrozek 07 Mar '18

07 Mar '18

Hi, I would like to release 1.16.1 tomorrow. There is one open ticket still in the milestone, but there is just a minor question in the PR (https://github.com/SSSD/sssd/pull/528) and even if we can’t merge that PR by tomorrow, I think the ticket should not be blocking the release. Is everyone OK with that? Below please see a draft of the release notes. Comments are welcome. SSSD 1.16.1 =========== Highlights ---------- New Features ^^^^^^^^^^^^ * A new option ``auto_private_groups`` was added. If this option is enabled, SSSD will automatically create user private groups based on user's UID number. The GID number is ignored in this case. Please see https://docs.pagure.org/SSSD.sssd/design_pages/auto_private_groups.html for more details on the feature. * The SSSD smart card integration now supports a special type of PAM conversation implemented by GDM which allows the user to select the appropriate smrt card certificate in GDM. Please refer to https://docs.pagure.org/SSSD.sssd/design_pages/smartcard_multiple_certifica… for more details about this feature. * A new API for accessing user and group information was added. This API is similar to the tradiional Name Service Switch API, but allows the consumer to talk to SSSD directly as well as to fine-tune the query with e.g. how cache should be evaluated. Please see https://docs.pagure.org/SSSD.sssd/design_pages/enhanced_nss_api.html for more information on the new API. * The ``sssctl`` command line tool gained a new command ``access-report``, which can generate who can access the client machine. Currently only generating the report on an IPA client based on HBAC rules is supported. Please see https://docs.pagure.org/SSSD.sssd/design_pages/attestation_report.html for more information about this new feature. * The ``hostid`` provider was moved from the IPA specific code to the generic LDAP code. This allows SSH host keys to be access by the generic LDAP provider as well. See the ``ldap_host_*`` options in the ``sssd-ldap`` manual page for more details. * Setting the ``memcache_timeout`` option to 0 disabled creating the memory cache files altogether. This can be useful in cases there is a bug in the memory cache that needs working around. Performance enhancements ^^^^^^^^^^^^^^^^^^^^^^^^ * Several internal changes to how objects are stored in the cache improve SSSD performance in environments with large number of objects of the same type (e.g. many users, many groups). In particular, several useless indexes were removed and the most common object types no longer use the indexed ``objectClass`` attribute, but use unindexed ``objectCategory`` instead (#3503) * In setups with ``id_provider=ad`` that use POSIX attributes which are replicated to the Global Catalog, SSSD uses the Global Catalog to determine which domain should be contacted for a by-ID lookup instead of iterating over all domains. More details about this feature can be found at https://docs.pagure.org/SSSD.sssd/design_pages/uid_negative_global_catalog.… Notable bug fixes ^^^^^^^^^^^^^^^^^ * A crash in ``sssd_nss`` that might have happened if a list of domains was refreshed while a NSS lookup using this request was fixed (#3551) * A potential crash in ``sssd_nss`` during netgroup lookup in case the netgroup object kept in memory was already freed (#3523) * Fixed a potential crash of ``sssd_be`` with two concurrent sudo refreshes in case one of them failed (#3562) * A memory growth issue in ``sssd_nss`` that occured when an entry was removed from the memory cache was fixed (#3588) * Two potential memory growth issues in the ``sssd_be`` process that could have hit configurations with ``id_provider=ad`` were fixed (#3639) * The ``selinux_child`` process no longer crashes on a system where SSSD is compiled with SELinux support, but at the same time, the SELinux policy is not even installed on the machine (#3618) * The memory cache consistency detection logic was fixed. This would prevent printing false positive memory cache corruption messages (#3571) * SSSD now remembers the last successfuly discovered AD site and use this for DNS search to lookup a site and forest during the next lookup. This prevents time outs in case SSSD was discovering the site using the global list of DCs where some of the global DCs might be unreachable. (#3265) * SSSD no longer starts the implicit file domain when configured with ``id_provider=proxy`` and ``proxy_lib_name=files``. This bug prevented SSSD from being used in setups that combine identities from UNIX files together with authentication against a remote source unless a files domain was explicitly configured (#3590) * The IPA provider can handle switching between different ID views better (#3579) * Previously, the IPA provider kept SSH public keys and certificates from an ID view in its cache and returned them even if the public key or certificate was then removed from the override (#3602, #3603) * FleetCommander profiles coming from IPA are applied even if they are assigned globally (to ``category: ALL``), previously, only profiles assigned to a host or a hostgroup were applied (#3449) * It is now possible to reset an expired password for users with 2FA authentication enabled (#3585) * A bug in the AD provider which could have resulted in built-in AD groups being incorrectly cached was fixed (#3610) * The SSSD watchdog can now cope better with time drifts (#3285) * The ``nss_sss`` NSS module's return codes for invalid cases were fixed * A bug in the LDAP provider that prevented setups with id_provider=proxy and auth_provider=ldap with LDAP servers that do not allow anonymous binds from working was fixed (#3451) Packaging Changes ----------------- * The FleetCommander desktop profile path now uses stricter permissions, 751 instead of 755 (#3621) * A new option ``--logger`` was added to the ``sssd(8)`` binary. This option obsoletes old options such as ``--debug-to-files``, although the old options are kept for backwards compatibility. Documentation Changes --------------------- There are no notable documentation changes such as options changing default values etc in this release. Tickets Fixed ------------- Detailed Changelog ------------------
