Subject: [PATCH] ipa: fix reply socket of selinux_child
Commit c92d39a30fa0162d4efdfbe5883c8ea9911a2249 accidentally switched
the reply socket of selinux_child from stdout to stderr while switching
from exec_child to exec_child_ex. This patch returns the original
behavior.

Subject: [PATCH] ad: add required 'cn' attribute to subdomain object
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
If the forest root is not part of the return trusted domain objects
from the local domain controller we generate an object for further
processing. During this processing it is expected that the 'cn'
attribute is set and contains the name of the forest root. So far this
attribute was missing and it is now added by this patch.

Subject: [PATCH] krb5: AD and IPA don't change Kerberos port
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
AD and IPA providers use a common fo_server object for LDAP and
Kerberos, which is created with the LDAP data. This means that due to
the changes introduced in
https://github.com/SSSD/sssd/commit/1e747fad4539ffb402010e73f78469fe57af408f
the port in use for the Kerberos requests would be the one specified for
LDAP, usually the default one (389).
In order to avoid that, AD and IPA providers shouldn't change the
Kerberos port with the one provided for LDAP.
:fixes: A critical regression that prevented authentication of users via
AD and IPA providers was fixed. LDAP port was reused for Kerberos
communication and this provider would send incomprehensible information
to this port.

touched

Even brief window inside `sss_nss_mc_destroy_ctx()` when `mutex == NULL`
was creating a possibility for a race.

Subject: [PATCH] SSSCTL: Allow analyzer to work without SSSD setup
Fixes an issue when the sssctl analyzer option is
used on systems where SSSD is not running or configured. This is
an expected use case when using --logdir option to analyze external
log files.

From 1b2e4760c52b9abd0d9b9f35b47ed72e79922ccc Mon Sep 17 00:00:00 2001
From: Alexey Tikhonov <atikhono@redhat.com>
Date: Thu, 25 Aug 2022 18:10:46 +0200
Subject: [PATCH] CLIENT: fix client fd leak
- close client socket at thread exit
- only build lock-free client support if libc has required
functionality for a proper cleanup
- use proper mechanisms to init lock_mode only once
:relnote:Lock-free client support will be only built if libc
provides `pthread_key_create()` and `pthread_once()`. For glibc
this means version 2.34+
