From 2bbfd1454fc69c5975826d1a3f39b301d135abb5 Mon Sep 17 00:00:00 2001

Subject: ipatests: restart ipa services after moving date
When system date is moved into future, it have unprecedented
behavior i.e CA becomes irresponsive or unexpected certificcate
state. Hence restart the ipa service after moving the date to
gracefully serve the request.

Date: Nov 17 2023 09:08:44 +0000
Subject: ipatests: ignore nsslapd-accesslog-logbuffering WARN in healthcheck
Log buffering is disabled in the integration tests so we can have all
the logs at the end. This is causing a warning to show in the 389-ds
checks and causing tests to fail that expect all SUCCESS.
Add an exclude for this specific key so tests will pass again.
We may eventually want a more sophisiticated mechanism to handle
excludes, or updating the config in general, but this is fine for now.

Some tools may pass None as NetBIOS name if not put explicitly by a
user. This meant to use default NetBIOS name generator based on the
domain (realm) name. However, this wasn't done properly, so None is
passed later to python-ldap and it rejects such LDAP entry.

> The value 0 indicates success; any other values are com_err codes. Use krb5_get_error_message() to obtain a string describing the error.

And this is what was actually used.
To prevent confusion of types `krb5_error` was replaced with
`krb5_error_code`.

Subject: ipapython: Propagate KRB5Error exceptions on iterating ccache
`ipapython.session_storage.get_data` iterates over
credentials in a credential cache till `krb5_cc_next_cred` returns
an error. This function doesn't expect any error on calling
other kerberos foreign functions during iteration. But that can
actually happen and KRB5Error exceptions stop an iteration while
they should be propagated.
With this change iteration will exactly stop on `krb5_cc_next_cred`
error as it was supposed to be.

Subject: ipa-kdb: Fix memory leak during PAC verification
Commit 0022bd70d93708d325855d5271516d6cd894d6e8 introduced a memory leak
during the copy of some PAC buffers, because of an unfreed memory
allocation context.

From: Alexander Bokovoy <abokovoy@redhat.com>
Date: Jan 31 2024 08:33:17 +0000
Subject: sidgen: ignore staged users when generating SIDs
Staged users have
uidNumber: -1
gidNumber: -1
ipaUniqueID: autogenerate
We cannot generate ipaSecurityIdentifier based on those UID/GID numbers.
However, '-1' value will trigger an error
find_sid_for_ldap_entry - [file ipa_sidgen_common.c, line 483]: ID value too large.
And that, in turn, will cause stopping SID generation for all users.
Detect 'ipaUniqueID: autogenerate' situation and ignore these entries.

Subject: ipatests: fix tasks.wait_for_replication method
With the fix for https://pagure.io/freeipa/issue/9171, the
method entry.single_value['nsds5replicaupdateinprogress'] now
returns a Boolean instead of a string "TRUE"/"FALSE".
The method tasks.wait_for_replication needs to be fixed so that
it properly detects when replication is not done.

Subject: ipa-kdb: Rework ipadb_reinit_mspac()
Modify ipadb_reinit_mspac() to allocate and initialize ipactx->mspac
only if all its attributes can be set. If not, ipactx->mspac is set to
NULL. This makes easier to determine if the KDC is able to generate PACs
or not.
Also ipadb_reinit_mspac() is now able to return a status message
explaining why initialization of the PAC generator failed. This message
is printed in KDC logs.
