Chapter 8. Bug fixes

Anaconda displays WWID identifiers for multipath storage devices on the Installation Destination screen

Previously, Anaconda did not display any details, for example, device number, WWPN, or LUN for the multipath storage devices. As a consequence, it was difficult to select the correct installation destination from the Installation Destination > Add a disk screen. With this update, Anaconda now displays WWID identifiers for multipath storage devices. As a result, you can now easily identify and select the required installation destination on the advanced storage device screen.

Installer now accepts additional time zone definitions in Kickstart files

Anaconda switched to a different, more restrictive method of validating time zone selections. This caused some time zone definitions, such as Japan, to be no longer valid despite being accepted in previous versions. Legacy Kickstart files with these definitions had to be updated. Otherwise, they would default to the Americas/New_York time zone.

The installer now correctly creates bond device with multiple ports and a BOOTIF option

Previously, the installation program created incorrect connection profiles when the installation was booted with a bond network device with multiple ports along with the BOOTIF boot option. Consequently, the device used by the BOOTIF option was not added to the bond device though it was configured as one of its ports.

Anaconda replaces the misleading error message when failing to boot an installation image

Previously, when the installation program failed to boot the installation image, for example due to missing source of stage2 specified in inst.stage2 or inst.repo, Anaconda displayed the following misleading error message:

The new version of xfsprogs no longer shrinks the size of /boot

Previously, the xfsprogs package with the 5.19 version in the RHEL 9.3 caused the size of /boot to shrink. As a consequence, it caused a difference in the available space on the /boot partition, if compared to the RHEL 9.2 version. This fix increases the /boot partition to 600 MiB for all images, instead of 500 MiB, and the /boot partition is no longer affected by space issues.

Libreswan accepts IPv6 SAN extensions

Previously, IPsec connection failed when setting up certificate-based authentication with a certificate that contained a subjectAltName (SAN) extension with an IPv6 address. With this update, the pluto daemon has been modified to accept IPv6 SAN as well as IPv4. As a result, IPsec connection is now correctly established with IPv6 address embedded in the certificate as an ID.

Rules for managing virtual routing with ip vrf are added to the SELinux policy

You can use the ip vrf command to manage virtual routing of other network services. Previously, selinux-policy did not contain rules to support this usage. With this update, SELinux policy rules allow explicit transitions from the ip domain to the httpd, sshd, and named domains. These transitions apply when the ip command uses the setexeccon library call.

SELinux policy denies SSH login for unconfined users when unconfined_login is set to off

Previously, the SELinux policy was missing a rule to deny unconfined users to log in via SSH when the unconfined_login boolean was set to off. As a consequence, with unconfined_login set to off, users still could log in with SSHD to an unconfined domain. This update adds a rule to the SELinux policy, and as a result, users cannot log in via sshd as unconfined when unconfined_login is off.

SELinux policy allows rsyslogd to execute confined commands

Previously, the SELinux policy was missing a rule to allow the rsyslogd daemon to execute SELinux-confined commands, such as systemctl. As a consequence, commands executed as an argument of the omprog directive failed. This update adds rules to the SELinux policy so that executables in the /usr/libexec/rsyslog directory that are run as an argument of omprog are in the syslogd_unconfined_script_t unconfined domain. As a result, commands executed as an argument of omprog finish successfully.

kmod runs in the SELinux MLS policy

Previously, the SELinux did not assign a private type for the /var/run/tmpfiles.d/static-nodes.conf file. As a consequence, the kmod utility may fail to work in the SELinux multi-level security (MLS) policy. This update adds the kmod_var_run_t label for /var/run/tmpfiles.d/static-nodes.conf to the SELinux policy, and as a result, kmod runs successfully in the SELinux MLS policy.

selinux-autorelabel runs in SELinux MLS policy

Previously, the SELinux policy did not assign a private type for the /usr/libexec/selinux/selinux-autorelabel utility. As a consequence, selinux-autorelabel.service might fail to work in the SELinux multi-level security (MLS) policy. This update adds the semanage_exec_t label to /usr/libexec/selinux/selinux-autorelabel, and as a result, selinux-autorelabel.service runs successfully in the SELinux MLS policy.

/bin = /usr/bin file context equivalency rule added to SELinux policy

Previously, the SELinux policy did not contain the /bin = /usr/bin file context equivalency rule. As a consequence, the restorecond daemon did not work correctly. This update adds the missing rule to the policy, and as a consequence, restorecond works correctly in SELinux enforcing mode.

SELinux policy contains rules for additional services and applications

This version of the selinux-policy package contains additional rules. Most notably, users in the sysadm_r role can execute the following commands:

SELinux policy adds permissions for QAT firmware

Previously, when updating the Intel QuickAssist Technology (QAT) with the Intel VT-d kernel option enabled, missing SELinux permissions caused denials. This update adds additional permissions for the qat service. As a result, QAT can be updated correctly.

Rsyslog can execute privileged commands through omprog

Previously, the omprog module of Rsyslog could not execute certain external programs, especially programs that contain privileged commands. As a consequence, the use of scripts that involve privileged commands through omprog was restricted. With this update, the SELinux policy was adjusted. Place your scripts into the /usr/libexec/rsyslog directory to ensure compatibility with the adjusted SELinux policy. As a result, Rsyslog now can execute scripts, including those with privileged commands, through the omprog module.

The semanage fcontext command no longer reorders local modifications

The semanage fcontext -l -C command lists local file context modifications stored in the file_contexts.local file. The restorecon utility processes the entries in the file_contexts.local from the most recent entry to the oldest. Previously, semanage fcontext -l -C listed the entries in an incorrect order. This mismatch between processing order and listing order caused problems when managing SELinux rules. With this update, semanage fcontext -l -C displays the rules in the correct and expected order, from the oldest to the newest.

CardOS 5.3 cards with offsets no longer cause problems in OpenSC

Previously, file caching did not work correctly for some CardOS 5.3 cards that stored certificates on different offsets of a single PKCS #15 file. This occurred because file caching ignored the offset part of the file, which caused repetitive overriding of the cache and reading invalid data from file cache. The problem was identified and fixed upstream, and after this update, CardOS 5.3 cards work correctly with the file cache.

subscription-manager no longer retains nonessential text in the terminal

Starting with RHEL 9.1, subscription-manager displays progress information while processing any operation. Previously, for some languages, typically non-Latin, progress messages did not clean up after the operation finished. With this update, all the messages are cleaned up properly when the operation finishes.

The librhsm library now returns the correct /etc/rhsm-host prefix if librhsm is run in a container

The librhsm library rewrites path prefixes to CA certificates from the /etc/rhsm to /etc/rhsm-host path if librhsm is run in a container. Previously, librhsm returned the wrong /etc/rhsm-host-host prefix because of a string manipulation mistake. With this update, the issue has been fixed, and the librhsm library now returns the correct /etc/rhsm-host prefix.

systemd now correctly manages the /run/user/0 directory created by librepo

Previously, if the librepo functions were called from an Insights client before logging in root, the /run/user/0 directory could be created with a wrong SELinux context type. This prevented systemd from cleaning the directory after you logged out from root.

systemd now correctly manages the /run/user/0 directory created by libdnf

Previously, if the libdnf functions were called from an Insights client before logging in root, the /run/user/0 directory could be created with a wrong SELinux context type. This prevented systemd from cleaning the directory after you logged out from root.

The dnf needs-restarting --reboothint command now recommends a reboot to update the CPU microcode

To fully update the CPU microcode, you must reboot a system. Previously, when you installed the microcode_ctl package, which contains the updated CPU microcode, the dnf needs-restarting --reboothint command did not recommend the reboot. With this update, the issue has been fixed, and dnf needs-restarting --reboothint now recommends a reboot to update the CPU microcode.

The top -u command now displays at least one process when you sort the processes by memory

Previously, when you executed the top command with the -u <user> parameter, where the user was different from the one running the command, all processes disappeared when the M key was pressed to sort the processes by memory. With this update, the top command displays at least one process when you sort the processes by memory.

ReaR now determines the presence of a BIOS boot loader when both BIOS and UEFI boot loaders are installed

Previously, in a hybrid boot loader setup (UEFI and BIOS), when UEFI was used to boot, Relax-and-Recover (ReaR) restored only the UEFI boot loader and not the BIOS boot loader. This would result in a system that had a GUID Partition Table (GPT), a BIOS Boot Partition, but not a BIOS boot loader. In this situation, ReaR failed to create the rescue image, the attempt to produce a backup or a rescue image by using the rear mkbackup or rear mkrescue command would fail with the following error message:

ReaR no longer uses the logbsize, sunit and swidth mount options during recovery

Previously, when restoring an XFS file system with the parameters different from the original ones by using the MKFS_XFS_OPTIONS configuration setting, Relax-and-Recover (ReaR) mounted this file system with mount options applicable for the original file system, but not for the restored file system. As a consequence, the disk layout recreation would fail with the following error message when ReaR ran the mount command :

ReaR recovery no longer fails on systems with a small thin pool metadata size

Previously, ReaR did not save the size of the pool metadata volume when saving a layout of an LVM volume group with a thin pool. During recovery, ReaR recreated the pool with the default size even if the system used a non-default pool metadata size.

ReaR now preserves logs from the bprestore command of NetBackup in the rescue system and the recovered system

Previously, when using the NetBackup integration (BACKUP=NBU), ReaR added the log from the bprestore command during recovery to a directory that was deleted on exit. Additionally, ReaR did not save further logs produced by the command under the /usr/openv/netbackup/logs/bprestore/ directory on the recovered system.

ReaR no longer fails during recovery if the TMPDIR variable is set in the configuration file

Previously, the ReaR default configuration file /usr/share/rear/conf/default.conf contained the following instructions:

wwan_hwsim is now in the kernel-modules-internal package

The wwan_hwsim kernel module provides a framework for simulating and testing various networking scenarios that use wireless wide area network (WWAN) devices. Previously, wwan_hwsim was a part of the kernel-modules-extra package. However, with this release, it is moved to the kernel-modules-internal package, which contains other similarly-oriented utilities. Note that the WWAN feature for PCI modem is still a Technology Preview.

The xdp-loader features command now works as expected

The xdp-loader utility was compiled against the previous version of libbpf. As a consequence, xdp-loader features failed with an error:

Mellanox ConnectX-5 adapter works in the DMFS mode

Previously, while using the Ethernet switch device driver model (switchdev) mode, the mlx5 driver failed if configured in the device managed flow steering (DMFS) mode on the ConnectX-5 adapter. Consequently, the following error message appeared:

crash was rebased to version 8.0.4

The crash utility was upgraded to version 8.0.4, which provides multiple bug fixes. Notable repairs include:

tuna launches GUI when needed

Previously, if you ran the tuna utility without any subcommand, it would launch the GUI. This behavior was desirable if you had a display. In the opposite case, tuna on a machine without a display would not exit gracefully. With this update, tuna detects whether you have a display, and the GUI is launched or not launched accordingly.

Intel TPM chips are now detected correctly

Previously, a side effect in a bug fix to AMD Trusted Platform Module (TPM) chips also affected Intel TPM chips. As a consequence, RHEL failed to detect certain Intel TPM chips.

RHEL previously failed to recognize NVMe disks when VMD was enabled

When you reset or reattached a driver, the Volume Management Device (VMD) domain previously did not soft-reset. Consequently, the hardware could not properly detect and enumerate its devices. With this update, the operating system with VMD enabled now correctly recognizes NVMe disks, especially when resetting a server or working with a VM machine.

multipathd now successfully removes devices that have outstanding queued I/O

Previously, the multipathd command did not disable the queue_if_no_path parameter before removing a device. This was possible only if there was an outstanding queued I/O to the multipath device itself, and not to the partition devices. Consequently, multipathd would hang, and could no longer maintain the multipath devices. With this update, the multipathd now disables queuing before executing the remove command such as multipath -F, multipath -f <device>, multipathd remove maps, or multipathd remove map <device>. As a result, multipathd now successfully removes devices that have outstanding queued I/O.

The no_read_workqueue, no_write_workqueue, and try_verify_in_taskle options of the dm-crypt and dm-verity devices are temporarily disabled

Previously, the dm-crypt devices created by using either the no_read_workqueue or no_write_workqueue option and dm-verity devices created by using the try_verify_in_tasklet option caused memory corruption. Consequently, random kernel memory was corrupted, which caused various system problems. With this update, these options are temporarily disabled. Note that this fix can cause dm-verity and dm-crypt to perform slower on some workloads.

Multipathd now checks if a device is incorrectly queuing I/O

Previously, a multipath device restarted queuing I/O, even though it was configured to fail, under the following conditions:

Removing duplicate entry from nvmf_log_connect_error

Previously, due to a duplicate commit merge error, a log message was repeated in the nvmf_log_connect_error kernel function. Consequently, when the kernel was unable to connect to a fabric-attached Non-volatile Memory Express (NVMe) device, the Connect command failed message appeared twice. With this update, the duplicate log message is now removed from the kernel, resulting in only a single log message available for each error.

The kernel no longer crashes when namespaces are added and removed

Previously, when NVMe namespaces were rapidly added and removed, a namespace disappeared between successive commands used to probe the namespace. In a specific case, a storage array did not return an invalid namespace error but instead returned a buffer filled with zero. Consequently, the kernel crashed due to the divide-by-zero error. With this update, the kernel now validates data from responses to both the Identify Namespace data structure issued to the storage. As a result, the kernel no longer crashes.

The newly allocated sections of the data device are now properly aligned

Previously, when a Stratis pool was expanded, it was possible to allocate the new regions of the pool. But the newly allocated regions were not correctly aligned with the previously allocated regions. Consequently, it could cause a performance degradation along with a nonzero entry in the Stratis thin pool’s alignment_offset file in sysfs. With this update, when the pool expands, the newly allocated region of the data device is properly aligned with the previously allocated region. As a result, there is no degradation in performance and no nonzero entry in the Stratis thin pool’s alignment_offset file in sysfs.

System boots correctly when adding a NVMe-FC device as a mount point in /etc/fstab

Previously, due to a known issue in the nvme-cli nvmf-autoconnect systemd services, systems failed to boot while adding the Non-volatile Memory Express over Fibre Channel (NVMe-FC) devices as a mount point in the /etc/fstab file. Consequently, the system entered into an emergency mode. With this update, a system boots without any issue when mounting an NVMe-FC device.

LUNs are now visible during the operating system installation

Previously, the system was not using the authentication information from firmware sources, specifically in cases involving iSCSI hardware offload with CHAP (Challenge-Handshake Authentication Protocol) authentication stored in the iSCSI iBFT (Boot Firmware Table). As a consequence, the iSCSI login failed during installation.

Configuring the tls and keep_active_partition_tie_breaker quorum device options without specifying --force

Previously, when configuring a quorum device, a user could not configure the tls and keep_active_partition_tie_breaker options for a quorum device model net without specifying the --force option. With this update, configuring these options no longer requires you to specify --force.

Issues with moving and banning clone and bundle resources now corrected

This bug fix addresses two limitations of moving bundled and clone resources:

Output of pcs status command no longer shows warning for expired constraints

Previously, when moving a cluster resource created a temporary location constraint, the pcs status command displayed a warning even after the constraint expired. With this fix, the pcs status command filters out expired constraints and they no longer generate a warning message in the command output.

Disabling the auto_tie_breaker quorum option no longer allowed when SBD fencing requires it

Previously, pcs allowed a user to disable the auto_tie_breaker quorum option even when a cluster configuration required this option for SBD fencing to work correctly. With this fix, pcs generates an error message when a user attempts to disable auto_tie_breaker on a system where SBD fencing requires that the auto_tie_breaker option be enabled.

httpd works correctly if a DAV repository location is configured by using a regular expression match

Previously, if a Distributed Authoring and Versioning (DAV) repository was configured in the Apache HTTP Server by using a regular expression match (such as LocationMatch), the mod_dav httpd module was unable to determine the root of the repository from the path name. As a consequence, httpd did not handle requests from third-party providers (for example, Sub-version’s mod_dav_svn module).

ldconfig no longer crashes after an interrupted system upgrade

Previously, the ldconfig utility terminated unexpectedly with a segmentation fault when processing incomplete shared objects left in the /usr/lib64 directory after an interrupted system upgrade. With this update, ldconfig ignores temporary files written during system upgrades. As a result, ldconfig no longer crashes after an interrupted system upgrade.

glibc now uses the number of configured processors for malloc arena tuning

Previously, glibc used the per-thread CPU affinity mask for tuning the maximum arena count for malloc. As a consequence, restricting the thread affinity mask to a small subset of CPUs in the system could lead to performance degradation.

Improved glibc compatibility with applications using dlclose on shared objects involved in a dependency cycle

Previously, when unloading a shared object in a dependency cycle using the dlclose function in glibc, that object’s ELF destructor might not have been called before all other objects were unloaded. As a consequence of this late ELF destructor execution, applications experienced crashes and other errors due to the initial shared object’s dependencies already being deinitialized.

make no longer tries to run directories

Previously, make did not check if an executable it was trying to run was actually an executable. Consequently, if the path included a directory with the same name as the executable, make tried to run the directory instead. With this update, make now does additional checks when searching for an executable. As a result, make no longer tries to run directories.

Improved glibc wide-character write performance

Previously, the wide stdio stream implementation in glibc did not treat the default buffer size as large enough for wide-character write operations and used a 16-byte fallback buffer instead, negatively impacting performance. With this update, buffer management is fixed and the entire write buffer is used. As a result, glibc wide-character write performance is improved.

The glibc getaddrinfo function now correctly reads ncsd cache information

Previously, a bug in the glibc getaddrinfo function would cause it to occasionally return empty elements in the list address information structure. With this update, the getaddrinfo function has been fixed to read and translate ncsd cache data correctly and, as a result, returns correct address information.

Improved glibc compatibility with applications using dlclose on shared objects involved in a dependency cycle

Previously, when unloading a shared object in a dependency cycle using the dlclose function in glibc, that object’s ELF destructor might not have been called before all other objects were unloaded. As a consequence of this late ELF destructor execution, applications experienced crashes and other errors due to the initial shared object’s dependencies already being deinitialized.

ncsd no longer fails to start due to inconsistent cache expiry information

Previously, the glibc Name Service Switch Caching Daemon (nscd) could fail to start due to inconsistent cache expiry information in the persistent cache file. With this update, ncsd now marks cache entries with inconsistent timing information for deletion and skips them. As a result, ncsd no longer fails to start due to inconsistent cache expiry information.

Consistently fast glibc thread-local storage performance

Previously, the glibc dynamic linker did not adjust certain thread-local storage (TLS) metadata after shared objects with TLS were loaded by using the dlopen() function, which consequently caused slow TLS access. With this update, the dynamic linker now updates TLS metadata for TLS changes caused by dlopen() calls. As a result, TLS access is consistently fast.

Allocated memory now released when an operation is completed

Previously, memory allocated by the KCM for each operation was not being released until the connection was closed. As a result, for client applications that opened a connection and ran many operations on the same connection, it led to a noticeable memory increase because the allocated memory was not released until the connection closed. With this update, the memory allocated for an operation is now released as soon as the operation is completed.

IdM clients correctly retrieve information for trusted AD users when their names contain mixed case characters

Previously, if you attempted a user lookup or authentication of a user, and that trusted Active Directory (AD) user contained mixed case characters in their names and they were configured with overrides in IdM, an error was returned preventing users from accessing IdM resources.

SSSD correctly returns an error if no grace logins remain while changing a password

Previously, if a user’s LDAP password had expired, SSSD tried to change the password even after the initial bind of the user failed as there were no more grace logins left. However, the error returned to the user did not indicate the reason for the failure. With this update, the request to change the password is aborted if the bind fails and SSSD returns an error message indicating there are no more grace logins and the password must be changed by another means.

Removing systems from a domain using the realm leave command

Previously, if multiple names were set for the ad_server option in the sssd.conf file, running the realm leave command resulted in parsing errors and the system was not removed from the domain. With this update, the ad_server option is properly evaluated and the correct domain controller name is used and the system is correctly removed from the domain.

KCM logs to the correct sssd.kcm.log file

Previously, logrotate correctly rotated the Kerberos Credential Manager (KCM) log files but KCM incorrectly wrote the logs to the old log file, sssd_kcm.log.1. If KCM was restarted, it used the correct log file. With this update, after logrotate is invoked, log files are rotated and KCM correctly logs to the sssd_kcm.log file.

The realm leave --remove command no longer asks for credentials

Previously, the realm utility did not correctly check if a valid Kerberos ticket was available when running the realm leave operation. As a result, users were asked to enter a password even though a valid Kerberos ticket was available. With this update, realm now correctly verifies if there is a valid Kerberos ticket and no longer requests the user to enter a password when running the realm leave --remove command.

KDC now runs extra checks when general constrained delegation requests is processed

Previously, the forwardable flag in Kerberos tickets issued by KDCs running on Red Hat Enterprise Linux 8 was vulnerable, allowing unauthorized modification without detection. This vulnerability could lead to impersonation attacks, even from or by users without specific privileges. With this update, KDC runs extra checks when it processes general constrained delegation requests, ensuring detection and rejection of unauthorized flag modifications, thus removing the vulnerability.

Check on the forwardable flag is disabled in cases where SIDs are generated for the domain

Previously, the update providing a fix for CVE-2020-17049 relied on the Kerberos PAC to run certain checks on the ticket forwardable flag when the KDC processes a general constrained delegation request. However, the PAC is generated only on domains where the SIDs generation task was executed in the past. While this task is automatically performed for all IdM domains created on Red Hat Enterprise Linux (RHEL) 8.5 and newer, domains initialized on older versions require manual execution of this task.

IdM Vault encryption and decryption no longer fails in FIPS mode

Previously, IdM Vault used OpenSSL RSA-PKCS1v15 as the default padding wrapping algorithm. However, none of the FIPS certified modules in RHEL supported PKCS#1 v1.5 as a FIPS approved algorithm, causing IdM Vault to fail in FIPS mode. With this update, IdM Vault supports the RSA-OAEP padding wrapping algorithm as a fallback. As a result, IdM Vault encryption and decryption now work correctly in FIPS mode.

Directory Server no longer fails after abandoning the paged result search

Previously, a race condition was a reason for heap corruption and Directory Server failure during abandoning paged result search. With this update, the race condition was fixed, and Directory Server failure no longer occurs.

If the nsslapd-numlisteners attribute value is more than 2, Directory Server no longer fails

Previously, if the nsslapd-numlisteners attribute value was higher than 2, Directory Server sometimes closed the listening file descriptor instead of the accepted file descriptor. As a consequence, a segmentation fault occurred in Directory Server. With this update, Directory Server closes the correct descriptor and continues listening on ports correctly.

The autobind operation now does not impacts operations performed on other connections

Previously, when the autobind operation was in progress, Directory Server stopped listening to new operations on any connection. With this update, the autobind operation does not impact the operations performed on the other connection.

The IdM client installer no longer specifies the TLS CA configuration in the ldap.conf file

Previously, the IdM client installer specified the TLS CA configuration in the ldap.conf file. With this update, OpenLDAP uses the default truststore and the IdM client installer does not set up the TLS CA configuration in the ldap.conf file.

Integration between shadow-utils and sss_cache for local user caching is disabled

In RHEL 9, the SSSD implicit files provider domain, which retrieves user information from local files such as /etc/shadow and group information from /etc/groups, was disabled by default. However, the integration in shadow-utils was not fully disabled, which resulted in calls to sss_cache when adding or deleting local users. The unnecessary cache updates caused performance issues for some users. With this update, the shadow-utils integration with sss_cache is fully disabled, and the performance issues caused by unnecessary cache updates no longer occur.

VNC console now works at most resolutions

Previously, when using the Virtual Network Computing (VNC) console under certain display resolutions, a mouse offset problem was present or only a part of the interface was visible. Consequently, using the VNC console was not possible.

Cluster start no longer times out when the SBD delay-start value is high

Previously, when a user configured SBD fencing in a cluster by using the ha_cluster system role and set the delay-start option to a value close to or higher than 90 seconds, the cluster start timed out. This is because the default systemd start timeout is 90 seconds, which the system reached before the SBD start delay value. With this fix, the ha_cluster system role overrides the sbd.service start timeout in systemd so that it is higher than the value of delay-start. This allows the system to start successfully even with high values of the delay-start option.

network role validates routing rules with 0.0.0.0/0 or ::/0

Previously, when the from: or to: settings were set to the 0.0.0.0/0 or ::/0 addresses in the routing rule, the network RHEL system role failed to configure the routing rule and rejected the settings as invalid. With this update, the network role allows 0.0.0.0/0 and ::/0 for from: and to: in routing rule validation. As a result, the role successfully configures the routing rules without raising the validation errors.

Running read-scale clusters and installing mssql-server-ha no longer requires certain variables

Previously, if you used the mssql RHEL system role to configure a read-scale cluster without certain variables (mssql_ha_virtual_ip, mssql_ha_login, mssql_ha_login_password, and mssql_ha_cluster_run_role), the role failed with an error message “Variable not defined”. However, these variables are not necessary to run a read-scale cluster. The role also tried to install the mssql-server-ha, which is not required for a read-scale cluster. With this fix, the requirement for these variables was removed. As a result, running a read-scale cluster proceeds successfully without the error message.

The Kdump system role works correctly when the kexec_crash_size file is busy

The /sys/kernel/kexec_crash_size file provides the size of the memory region allocated for crash kernel memory.

selinux role no longer uses the item loop variable

Previously, the selinux RHEL system role used the  item loop variable. This might have resulted in the following warning message when you called the selinux role from another role:

The ha_cluster system role now correctly configures a firewall on a qnetd host

Previously, when a user configured a qnetd host and set the ha_cluster_manage_firewall variable to true by using the ha_cluster system role, the role did not enable high-availability services in the firewall. With this fix, the ha_cluster system role now correctly configures a firewall on a qnetd host.

The postgresql RHEL system role now installs the correct version of PostgreSQL

Previously, if you tried to run the postgresql RHEL system role with the postgresql_version: "15" variable defined on a RHEL managed node, PostgreSQL version 13 was installed instead of version 15. This bug has been fixed, and the postgresql role installs the version set in the variable.

keylime_server role correctly reports registrar service status

Previously, when the keylime_server role playbook provided incorrect information, the role incorrectly reported the start as successful. With this update, the role now correctly reports a failure when incorrect information is provided, and the timeout when waiting for opened ports has been reduced from approximately 300 seconds to approximately 30 seconds.

The podman RHEL system role now sets and cancels linger properly for rootless containers

Previously, the podman RHEL system role did not set and cancel linger properly for rootless containers. Consequently, deploying secrets or containers for rootless users produced errors in some cases, and failed to cancel linger when removing resources in some cases. With this update, the podman RHEL system role ensures that linger is enabled for rootless users before doing any secret or container resource management, and ensures that linger is canceled for rootless users when there are no more secrets or container resources to be managed. As a result, the role correctly manages lingering for rootless users.

nbde_server role now works with socket overrides

Previously, the nbde_server RHEL system role assumed that the only file in the tangd socket override directory was the override.conf file for a custom port. Consequently, the role deleted the directory if there was no port customization without checking other files, and the system re-created the directory in subsequent runs.

A volume quadlet service name no longer fails

Previously, starting the volume service name produced an error similar to the following one: "Could not find the requested service NAME.volume: host" With this update, the volume quadlet service name is changed to basename-volume.service. As a result, the volume service starts with no errors.

Ansible now preserves JSON strings for use in secrets

Previously, Ansible converted JSON strings to the corresponding JSON object if the value was used in a loop and strings similar to data: "{{ value }}" As a consequence, you cannot pass JSON strings as secrets and have the value preserved. This update casts the data value to a string when passing to the podman_secret module. As a result, JSON strings are preserved as-is for use in secrets.

The rhc system role no longer fails on the registered systems when rhc_auth contains activation keys

Previously, a failure occurred when you executed playbook files on the registered systems with the activation key specified in the rhc_auth parameter. This issue has been resolved. It is now possible to execute playbook files on the already registered systems, even when activation keys are provided in the rhc_auth parameter.

RT VMs with a FIFO scheduler now boots correctly

Previously, after setting a real-time (RT) virtual machine (VM) to use the fifo setting for the vCPU scheduler, the VM became unresponsive when you attempted to boot it. Instead, the VM displayed the Guest has not initialized the display (yet) error. With this update, the error has been fixed, and setting fifo for the vCPU scheduler works as expected in the described circumstances.

A dump failure no longer blocks IBM Z VMs with Secure Execution from running

Previously, when a dump of an IBM Z virtual machine (VM) with Secure Execution failed, the VM remained in a paused state and was blocked from running. For example, dumping a VM by using the virsh dump command fails if there is not enough space on the disk.

The installation program shows the expected system disk to install RHEL on VM

Previously, when installing RHEL on a VM using virtio-scsi devices, it was possible that these devices did not appear in the installation program because of a device-mapper-multipath bug. Consequently, during installation, if some devices had a serial set and some did not, the multipath command was claiming all the devices that had a serial. Due to this, the installation program was unable to find the expected system disk to install RHEL in the VM.

Using a large number of queues no longer causes VMs to fail

Previously, virtual machines (VMs) might have failed when the virtual Trusted Platform Module (vTPM) device was enabled and the multi-queue virtio-net feature was configured to use more than 250 queues.

Windows guests boot more reliably after a v2v conversion on hosts with AMD EPYC CPUs

After using the virt-v2v utility to convert a virtual machine (VM) that uses Windows 11 or a Windows Server 2022 as the guest OS, the VM previously failed to boot. This occurred on hosts that use AMD EPYC series CPUs. Now, the underlying code has been fixed and VMs boot as expected in the described circumstances.

nodedev-dumpxml lists attributes correctly for certain mediated devices

Before this update, the nodedev-dumpxml utility did not list attributes correctly for mediated devices that were created using the nodedev-create command. This has been fixed, and nodedev-dumpxml now displays the attributes of the affected mediated devices properly.

virtiofs devices could not be attached after restarting virtqemud or libvirtd

Previously, restarting the virtqemud or libvirtd services prevented virtiofs storage devices from being attached to virtual machines (VMs) on your host. This bug has been fixed, and you can now attach virtiofs devices in the described scenario as expected.

Hot plugging a Watchdog card to a virtual machine no longer fails

Previously, if no PCI slots were available, adding a Watchdog card to a running virtual machine (VM) failed with the following error:

blob resources now work correctly for virtio-gpu on IBM Z

Previously, the virtio-gpu device was incompatible with blob memory resources on IBM Z systems. As a consequence, if you configured a virtual machine (VM) with virtio-gpu on an IBM Z host to use blob resources, the VM did not have any graphical output.

Reinstalling virtio-win drivers no longer causes DNS configuration to reset on the guest

In virtual machines (VMs) that use a Windows guest operating system, reinstalling or upgrading virtio-win drivers for the network interface controller (NIC) previously caused DNS settings in the guest to reset. As a consequence, your Windows guest in some cases lost network connectivity.

The repair function of virtio-win-guest-tool for the virtio-win drivers now works correctly

Previously, when using the Repair button of virtio-win-guest-tool for a virtio-win driver, such as the Virtio Balloon Driver, the button had no effect. As a consequence, the driver could not be reinstalled after being removed on the guest. This problem has been fixed and the virtio-win-guest-tool repair function now works correctly in the described circumstances.
