Chapter 8. Bug fixes This part describes bugs fixed in Red Hat Enterprise Linux 8.8 that have a significant impact on users. 8.1. Installer and image creation Installer now lists all PPC PreP Boot or BIOS Boot partitions during custom partitioning Previously, when adding multiple PPC PreP Boot or BIOS Boot partitions during custom partitioning, the Custom Partitioning screen displayed only one partition of a related type. As a consequence, the Custom Partitioning screen did not reflect the real state of the intended partitioning layout, making the partitioning process difficult and non-transparent. With this update, the Custom Partitioning screen correctly displays all PPC PreP Boot or BIOS Boot partitions in the partitions list. As a result, users can now better understand and manage the intended partitioning layout. Bugzilla:1913035 The installer now adds configuration options correctly into the yum repo files Previously, the installer did not add configuration options correctly into yum repo files while including and excluding packages from additional installation repositories. With this update, yum repo files are created correctly. As a result, using the --excludepkgs= or --includepkgs= options in the repo kickstart command now excludes or includes the specified packages during installation as expected. Bugzilla:2014103 Using the filename DHCP option no longer blocks downloading the kickstart file for installation Previously, when building a path for getting the kickstart file from an NFS server, the installer did not consider the filename DHCP option. As a consequence, the installer did not download the kickstart file and was blocking the installation process. With this update, the filename DHCP option correctly constructs a path to the kickstart file. As a result, the kickstart file is downloaded properly, and the installation process starts correctly. Bugzilla:1991516 The installer now creates a new GPT disk layout while custom partitioning Previously, the installer did not change the disk layout to GPT when inst.gpt was specified on the kernel command line, and the user removed all partitions from a disk with the MBR disk layout on the custom partitioning spoke. As a consequence, the MBR disk layout remained on the disk. With this update, the installer creates a new GPT disk layout on the disk if inst.gpt is specified on the kernel command line, and all partitions are removed from a disk on the custom partitioning spoke. Bugzilla:2094977 The --size parameter of the composer-cli compose start command now treats its values as MiB Previously, when using the composer-cli compose start --size size_value blueprint_name image_type command, the composer-cli tool treated the --size parameter values as byte units. This update fixes the issue, and the --size parameter values are now correctly used in the MiB format. Bugzilla:2033192 8.2. Software management RPM no longer hangs during a transaction involving the fapolicyd service restart Previously, if you tried to update a package that caused the fapolicyd service to be restarted, for example, systemd , the RPM transaction stopped responding because the fapolicyd plug-in failed to communicate with the fapolicyd daemon. With this update, the fapolicyd plug-in now correctly communicates with the fapolicyd daemon. As a result, RPM no longer hangs during a transaction which involves the fapolicyd service restart. Bugzilla:2110787 Security YUM upgrade is now possible for packages that change their architecture through the upgrade Patch for BZ#2088149 introduced with RHBA-2022:7711 caused a regression where YUM upgrade using security filters skipped packages that changed their architecture from or to noarch through the upgrade. Consequently, the missing security upgrades for these packages could leave the system in a vulnerable state. With this update, the issue has been fixed, and security YUM upgrade no longer skips packages that change architecture from or to noarch . Bugzilla:2124483 Reverting a YUM upgrade transaction is now possible for a package group or environment Previously, the yum history rollback command failed when attempting to revert an upgrade transaction for a package group or an environment. With this update, the issue has been fixed, and you can now revert the YUM upgrade transaction for a package group or environment. Bugzilla:2016070 8.3. Shells and command-line tools wsmancli handles HTTP 401 Unauthorized statuses correctly The wsmancli utility for managing systems using Web Services Management protocol now handles authentication to better conform to RFC 2616. Previously, when connecting to a service that requires authentication, the wsmancli command returned the error message Authentication failed, please retry immediately after receiving an HTTP 401 Unauthorized response, for example, because of incomplete credentials. To proceed, wsmancli prompted you to provide both the username and the password, even in situations where you had already provided a part of your credentials. With this update, wsmancli requires only credentials that were not previously provided. As a result, the first authentication attempt does not display any error message. An error message is displayed only after you provide the complete credentials and authentication fails. Bugzilla:2105316 The translator.sty LaTeX style document has been added Previously, the translator.sty LaTeX style document, which is necessary for certain tools that depend on texlive-beamer , was missing. As a consequence, these tools failed with a LaTeX Error: File `translator.sty' not found. error. This update adds the missing texlive-translator package that contains the translator.sty LaTeX style document. As a result, tools that depend on texlive-beamer work correctly. Bugzilla:2150727 ReaR handles excluded DASDs on the IBM Z architecture correctly Previously on the IBM Z architecture, ReaR reformatted all connected Direct Access Storage Devices (DASD) during the recovery process, including those DASDs that users excluded from the saved layout and did not intend to restore their content. As a consequence, if you excluded some DASDs from the saved layout, their data were lost during system recovery. With this update, ReaR no longer formats excluded DASDs during system recovery, including the device from which the ReaR rescue system was booted (using the zIPL bootloader). You are also prompted to confirm the DASD formatting script before ReaR reformats DASDs. This ensures that the data on excluded DASDs survive a system recovery. Bugzilla:2172605 ReaR no longer fails to restore non-LVM XFS filesystems Previously, when you used ReaR to restore a non-LVM XFS filesystems with certain settings and disk mapping, ReaR created the file system with the default settings instead of the specified settings. For example, if you had a file system with the sunit and swidth parameters set to non-zero values and you restored the file system using ReaR with disk mapping, the file system would be created with default sunit and swidth parameters ignoring the specified values. As a consequence, ReaR failed during mounting the filesystem with specific XFS options. With this update, ReaR correctly restores the file system with the specified settings. Bugzilla:2131946 8.4. Infrastructure services rsync no longer fails while using regular expressions for extended attributes Previously, the rsync utility for transferring and synchronizing files was not able to handle extended attributes in RHEL 8 correctly. For example, if you passed the --delete option together with the --filter '-x string .*' option for extended attributes to the rsync command, and a file on your system satisfied the regular expression, this resulted in an error message stating protocol incompatibilities. With this update, the rsync utility handles extended attributes correctly and you can use regular expressions for these attributes. Bugzilla:2139118 8.5. Security Scans and remediations correctly ignore SCAP Audit rules Audit key Previously, Audit watch rules that were defined without an Audit key ( -k or -F key) encountered the following problems: The rules were marked as non-compliant even if other parts of the rule were correct. Bash remediation fixed the path and permissions of the watch rule, but it did not add the Audit key correctly. Remediation sometimes did not fix the missing key, returning an error instead of a fixed value. This affected the following rules: audit_rules_login_events audit_rules_login_events_faillock audit_rules_login_events_lastlog audit_rules_login_events_tallylog audit_rules_usergroup_modification audit_rules_usergroup_modification_group audit_rules_usergroup_modification_gshadow audit_rules_usergroup_modification_opasswd audit_rules_usergroup_modification_passwd audit_rules_usergroup_modification_shadow audit_rules_time_watch_localtime audit_rules_mac_modification audit_rules_networkconfig_modification audit_rules_sysadmin_actions audit_rules_session_events audit_rules_sudoers audit_rules_sudoers_d With this update, the Audit key has been removed from checks and from Bash and Ansible remediations. As a result, inconsistencies caused by the key field during checking and remediating no longer occur, and auditors can choose these keys arbitrarily to make searching Audit logs easier. Bugzilla:2119356 crypto-policies no longer creates unnecessary symlink During system installation, the crypto-policies scriptlet creates symlinks from the /usr/share/crypto-policies/DEFAULT file or /usr/share/crypto-policies/FIPS in FIPS mode and saves them in the /etc/crypto-policies/back-ends directory. Previously, crypto-policies incorrectly included directories, and created a /etc/crypto-policies/back-ends/.config symlink that pointed to the /usr/share/crypto-policies/DEFAULT or /usr/share/crypto-policies/FIPS directories. With this update, crypto-policies does not create symlinks from directories, and therefore does not create this unnecessary symlink. Bugzilla:1921646 crypto-policies now disable NSEC3DSA for BIND Previously, the system-wide cryptographic policies did not control the NSEC3DSA algorithm in the BIND configuration. Consequently, NSEC3DSA , which does not meet current security requirements, was not disabled on DNS servers. With this update, all cryptographic policies disable NSEC3DSA in the BIND configuration by default. Bugzilla:2071981 Libreswan no longer rejects SHA-1 signature verification in the FUTURE and FIPS cryptographic policies Previously, from update to 4.9, Libreswan rejected SHA-1 signature verification in the FUTURE and FIPS cryptographic policies, and peer authentication failed when authby=rsasig or authby=rsa-sha1 connection options were used. This update reverts this behavior by relaxing how Libreswan handles the crypto-policies settings. As a consequence, you can now use the authby=rsasig and authby=rsa-sha1 connection options using SHA-1 signature verification. Bugzilla:2176248 crontab bash scripts no longer execute in incorrect context Previously, a bug fix published in erratum RHBA-2022:7691 used too general transition rule. Consequently, a bash script executed from the crontab file was executed in the rpm_script_t context instead of the system_cronjob_t context. With this update, bash scripts are now executed in the correct context. Bugzilla:2154242 selinux-policy supports service execution in SAP Host Agent Previously, the SELinux policy did not support the insights-client service interacting with SAP Host Agent and other services. As a consequence, some commands did not work correctly when started from Red Hat Insights. With this update, the SELinux policy supports SAP service execution. As a result, SAP services started from Insights run successfully. Bugzilla:2134125 selinux-policy now allows pmcd to execute its private memfd: objects Previously, the SELinux policy did not allow the pmcd process from the Performance Co-Pilot (PCP) framework to execute its private memory file-system objects ( memfd: ). Consequently, SELinux denied the Performance Metric Domain Agent (PMDA) BPF Compiler Collection (BCC) service to execute memfd: objects. In this update, the SELinux policy contains new rules for pcmd . As a result, pmcd can now execute memfd: objects with SELinux in enforcing mode. Bugzilla:2090711 SELinux policy allows sysadm_r to use subscription-manager Previously, users in the sysadm_r SELinux role were not allowed to execute some subcommands of the subscription-manager utility. Consequently, the subcommands failed to read the memory device. This update adds a new rule to the SELinux policy that allows the sysadm_t type to read /dev/mem . As a consequence, the subscription-manager subcommands do not fail. Bugzilla:2101341 samba-dcerpcd process now works correctly with nscd Previously, the samba-dcerpcd process could not communicate with the nscd process because of the SELinux policy. Consequently, the samba-dcerpcd service did not work properly when the nscd service was enabled. With this update, the SELinux policy has been updated with new rules for samba-dcerpcd . Bugzilla:2121709 vlock now works properly for confined users Previously, the confined user could not use vlock due to SELinux policy. Consequently, the vlock command did not work properly for confined users. With this update, the SELinux policy has been updated with new rules for confined users. Bugzilla:2122838 Confined users now can log in without a reported denial Previously, SELinux policy did not allow all permissions needed to log in a SELinux confined user using GUI. Consequently, AVC denials were audited and some services like dbus or pulseaudio did not work properly. With this update, the SELinux policy has been updated with new rules for confined users. Bugzilla:2124388 insights-client now has additional permissions in the SELinux policy The updated insights-client service requires additional permissions, which were not included in the versions of the selinux-policy packages. As a consequence, certain components of insights-client did not work correctly with SELinux in enforcing mode, and the system reported access vector cache (AVC) error messages. This update adds the missing permissions to the SELinux policy. As a result, insights-client now works correctly without reporting AVC errors. Bugzilla:2125008 The SELinux policy allows smb access to user shares Previously, the samba-dcerpcd process was separated from the smb service, but did not have access to user shares. As a consequence, smb clients could not access files on user smb shares. This update adds rules to the SELinux policy for managing user home content for the samba-dcerpcd binary when the samba_enable_home_dirs boolean is enabled. As a result, samba-dcerpcd can access user shares when samba_enable_home_dirs is on. Bugzilla:2143696 The SELinux policy now allows confined administrators to access ipmi devices when IPMItool runs Previously, the SELinux policy did not allow confined administrators to read and write ipmi devices when the IPMItool utility is run. As a consequence, when a confined administrator ran ipmitool , it failed. This update adds allow rules to selinux-policy for administrators assigned to the sysadm_r SELinux role. As a result, if a confined administrator runs ipmitool it works correctly. Bugzilla:2148561 SCAP Security Guide rule file_permissions_sshd_private_key is aligned with STIG configuration RHEL-08-010490 Previously, the implementation of rule file_permissions_sshd_private_key allowed private SSH keys to be readable by the ssh_keys group with mode 0644 , while DISA STIG version RHEL-08-010490 required private SSH keys to have mode 0600 . As a consequence, evaluation with DISA's automated STIG benchmark failed for configuration RHEL-08-010490. For this update, we worked with DISA to align the expected permissions for private SSH keys, and now private keys are expected to have mode 0644 or less permissive. As a result, the rule file_permissions_sshd_private_key and configuration RHEL-08-010490 are now aligned. Bugzilla:2115343 The sudo_require_reauthentication SCAP Security Guide rule accepts correct spacing in sudoers Previously, a bug in the checking of the xccdf_org.ssgproject.content_rule_sudo_require_reauthentication rule caused it to require specific spacing between the timestamp_timeout key and its value in the /etc/sudoers file and the /etc/sudoers.d directory. Consequently, valid and compliant syntax caused the rule to fail incorrectly. With this update, the check for xccdf_org.ssgproject.content_rule_sudo_require_reauthentication has been updated to accept blank spaces around the equal sign. As a result, the rule accepts correct and compliant definitions of timestamp_timeout with any of the following spacing formats: Defaults timestamp_timeout = 5 Defaults timestamp_timeout= 5 Defaults timestamp_timeout =5 Defaults timestamp_timeout=5 Bugzilla:2152208 Old Kerberos rules changed to notapplicable in new versions of RHEL Previously, some Kerberos-related rules failed while scanning against the DISA STIG profile on RHEL 8.8 and later systems in FIPS mode, even though the system should have been compliant. This was caused by the following rules: xccdf_org.ssgproject.content_rule_package_krb5-server_removed xccdf_org.ssgproject.content_rule_package_krb5-workstation_removed xccdf_org.ssgproject.content_rule_kerberos_disable_no_keytab This update makes these rules not applicable for RHEL versions 8.8 and later. As a result, the scan correctly returns the notapplicable result for these rules. Bugzilla:2099394 scap-security-guide STIG profiles no longer require specific text in /etc/audit/rules.d/11-loginuid.rules Previously, the SCAP rule audit_immutable_login_uids used in RHEL 8 profiles stig and stig_gui passed only if file /etc/audit/rules.d/11-loginuid.rules contained exact text. This is, however, not necessary to fulfill the STIG requirement (RHEL-08-030122). With this update, the new rule audit_rules_immutable_login_uids replaces audit_immutable_login_uids in RHEL 8 stig and stig_gui profiles. As a result, you can now specify the --loginuid-immutable parameter that fulfills the rule in any file with the .rules extension within the /etc/audit/rules.d directory or in the /etc/audit/audit.rules file, depending on usage of auditctl or augen-rules . Bugzilla:2151553 Rules for CIS profiles in scap-security-guide are better aligned Previously, some rules were incorrectly assigned to certain Center for Internet Security (CIS) profiles ( cis , cis_server_l1 , cis_workstation_1 , and cis_workstation_l2 ). As a consequence, scanning according to some CIS profiles could skip rules from the CIS benchmark or check for unnecessary rules. The following rules were assigned to incorrect profiles: Rules kernel_module_udf_disabled , sudo_require_authentication and kernel_module_squashfs_disabled were incorrectly placed in CIS Server Level 1 and CIS Workstation Level 1. Rules package_libselinux_installed , grub2_enable_selinux , selinux_policytype , selinux_confinement_of_daemons , rsyslog_nolisten , service_systemd-journald_enabled were missing from CIS Server Level 1 and CIS Workstation Level 1 profiles. Rules package_setroubleshoot_removed and package_mcstrans_removed were missing from the CIS Server Level 1 profile. This update assigns the misaligned rules to the correct CIS profiles, but does not introduce new rules or entirely removes any rules. As a result, SCAP CIS profiles are better aligned with the original CIS benchmark. Bugzilla:2162803 Clevis ignores commented devices in crypttab Previously, Clevis tried to unlock commented devices in the crypttab file, causing the clevis-luks-askpass service to run even if the device was not valid. This caused unnecessary service runs and made it difficult to troubleshoot. With this fix, Clevis ignores commented devices. Now, if an invalid device is commented, Clevis does not attempt to unlock it and clevis-luks-askpass.service finishes appropriately. This makes it easier to troubleshoot and reduces unnecessary service runs. Bugzilla:2159440 Clevis no longer requests too much entropy from pwmake Previously, the pwmake password generation utility displayed unwanted warnings when Clevis used pwmake to create passwords for storing data in LUKS metadata, which caused Clevis to use lower entropy. With this update, Clevis is limited to 256 entropy bits provided to pwmake , which eliminates an unwanted warning and uses the correct amount of entropy. Bugzilla:2159736 logrotate no longer incorrectly signals Rsyslog in log rotation Previously, the argument order was incorrectly set in the logrotate script, which caused a syntax error. This resulted in logrotate not correctly signaling Rsyslog during log rotation. With this update, the order of the arguments in logrotate is fixed and logrotate signals Rsyslog correctly after log rotation even when the POSIXLY_CORRECT environment variable is set. Bugzilla:2070496 Rsyslog no longer crashes due to a bug in imklog Previously, Rsyslog could encounter a segmentation fault if the imklog module was enabled and a free() call using an invalid object was freed during use. With this update, the freed object is correctly deallocated at the correct place. As a result, the segmentation fault no longer occurs. Bugzilla:2157658 USBGuard no longer causes a confusing warning Previously, a race condition could happen in USBGuard when a parent process finished sooner than the first child process. As a consequence, systemd reported that a process was present with a wrongly identified parent PID (PPID). With this update, a parent process waits for the first child process to finish in working mode. As a result, systemd no longer reports such warnings. Bugzilla:2159409 The usbguard service file did not define OOMScore Previously, the usbguard service file did not define the OOMScoreAdjust option. Consequently, the process could be identified as a candidate for killing before unprivileged processes when the system resources are closed to running out. With this update, the new OOMScoreAdjust setting was introduced to the usbguard.service file, to disable OOM killing processes of the usbguard unit. Bugzilla:2159411 USBGuard saves rules even if RuleFile is not defined Previously, if the RuleFile configuration directive in USBGuard was set but RuleFolder was not, the rule set could not be changed. With this update, you can now change the rule set even if RuleFolder is set but RuleFile is not. As a result, you can modify the permanent policy in USBGuard to permanently save newly added rules. Bugzilla:2159413 8.6. Networking xdp-tools rebased to version 1.2.10 The xdp-tools packages have been upgraded to upstream version 1.2.10, which provides a number of bug fixes over the version. Bugzilla:2160069 conntrackd functions properly even if HashSize and HashLimit are not set manually Previously, the conntrackd service did not set default values for the HashSize and HashLimit configuration variables. Consequently, conntrackd could become unstable or stop functioning entirely if you did not specify those values. The problem has been fixed by making the configuration reader set the default values for HashSize and HashLimit before conntrackd parses the configuration file. As a result, conntrackd now functions correctly even if you do not specify the values. Bugzilla:2126736 The nm-cloud-setup service no longer removes routes and manually-configured secondary IP addresses from interfaces Based on the information received from the cloud environment, the nm-cloud-setup service configures network interfaces. Previously, administrators had to disable nm-cloud-setup to manually configure routes and secondary IP addresses on interfaces to avoid that the service removes them. This update adds a flag to the Reapply() function to preserve externally added addresses and routes. As a result, administrators no longer need to disable the nm-cloud-setup service in the mentioned scenario. Bugzilla:2132754 8.7. Kernel kpatch-patch works correctly on systems with an idle isolated CPU Previously, when you attempted to install kpatch-patch CVE mitigation packages on systems with the kernel CPU isolation feature, the kpatch-patch RPMs did install, but failed to load their CVE mitigation kernel module. With this fix, the two features co-exist, and you can now successfully deploy kpatch CVE fixes when CPU isolation is in place. Bugzilla:2134931 Enabling VMD works again Previously, the operating system would fail to boot if Volume Management Device (VMD) was enabled. This update provides numerous bug fixes essential for VMD to work as expected. Bugzilla:2127028 8.8. File systems and storage System works correctly without the soft lockup while starting a VDO volume Due to fixing a Kernel Application Binary Interface (kABI) bug in the pv_mmu_ops structure, RHEL 8.7 systems with kernel version 4.18.0-425.10.1.el8_7 , that is RHEL-8.7.0.2-BaseOS, hung or encountered a kernel panic due to soft lockup while starting a Virtual Data Optimizer (VDO) volume. With this update, the kmod-kvdo package was rebuilt any time a new kernel was available that is no longer kABI compatible with the current version of kmod-kvdo . As a result, the system works correctly while starting a VDO volume. Bugzilla:2119819 VDO driver bug no longer causing device freezes through journal blocks Previously, a bug in the VDO driver caused the system to mark some journal blocks as waiting for metadata updates. This problem was triggered when increasing the size of the VDO pool or the logical volume on top of it, or when using the pvmove and lvchange operations on LVM tools managed VDO devices. The bug was caused by incomplete resets that left some journal pages unavailable for use, and an incorrect notion of how many slots in the recovery journal were available to be filled. As a result, the device would freeze. This issue has now been fixed with the latest version of the kernel modules for the virtual data optimizer kmod-kvdo-6.2.8.1-87.el8 . Currently, all incomplete metadata blocks are saved in each section of the code in phases, while also updating in-memory data structures and resetting state on resume if needed. With this fix, users should no longer experience device freezes due to this issue. Bugzilla:2109047 8.9. High availability and clusters pcs no longer allows you to modify cluster properties that should not be changed Previously, the pcs command line interface allowed you to modify cluster properties that should not be changed or for which change does not take effect. With this fix, pcs no longer allows you to modify these cluster properties: cluster-infrastructure , cluster-name , dc-version , have-watchdog , and last-lrm-refresh . Bugzilla:2112263 pcs now displays cluster properties that are not explicitly configured Previously, a pcs command to display the value of a specific cluster property did not list values that are not explicitly configured in the CIB. With this fix, if a cluster property is not set pcs displays the default value for the property. Bugzilla:2112267 Cluster resources that call crm_mon now stop cleanly at shutdown Previously, the crm_mon utility returned a nonzero exit status while Pacemaker was in the process of shutting down. Resource agents that called crm_mon in their monitor action, such as ocf:heartbeat:pqsql , could incorrectly return a failure at cluster shutdown. With this fix, crm_mon returns success even if the cluster is in the process of shutting down. Resources that call crm_mon now stop cleanly at cluster shutdown. Bugzilla:2133497 OCF resource agent metadata actions can now call crm_node without causing unexpected fencing As of RHEL 8.5, OCF resource agent metadata actions blocked the controller and crm_node queries performed controller requests. As a result, if an agent's metadata action called crm_node , it blocked the controller for 30 seconds until the action timed out. This could cause other actions to fail and the node to be fenced. With this fix, the controller now performs metadata actions asynchronously. An OCF resource agent metadata action can now call crm_node without issue. Bugzilla:2121852 Enabling a single resource and monitoring operation no longer enables monitoring operations for all resources in a resource group Previously, after unmanaging all resources and monitoring operations in a resource group, managing one of the resources in that group along with its monitoring operation re-enabled the monitoring operations for all resources in the resource group. This could trigger unexpected cluster behavior. With this fix, managing a resource and re-enabling its monitoring operation re-enables the monitoring operation for that resource only and not for the other resources in a resource group. Bugzilla:1918527 Pacemaker now rechecks resource assignments immediately when resource order changes As of RHEL 8.7, Pacemaker did not recheck resource assignments when the order of resources in the CIB changed with no changes to the resource definition. If configuration reordering would cause resources to move, that would not take place until the natural transition, up to the value of cluster-recheck-interval-property . This could cause issues if resource stickiness is not configured for a resource. With this change, Pacemaker rechecks resource assignments when the order of the resources in the CIB changes, as it did for earlier Pacemaker releases. The cluster now responds immediately to these changes, if needed. Bugzilla:2122806 8.10. Compilers and development tools You can install SciPy using pip on all architectures Previously, the openblas-devel package did not contain a pkg-config file for the OpenBLAS library. As a consequence, in certain scenarios, it was impossible to determine the compiler and linker flags using the pkgconf utility while compiling with OpenBLAS. For example, this caused a failure of the pip install scipy command on the 64-bit IBM Z and IBM Power Systems, Little Endian architectures. This update adds the openblas.pc file to the openblas-devel package on all supported architectures. As a result, you can install the SciPy library using the pip package installer. Bugzilla:2115722 Functions in go no longer cause memory leak Previously, the EVP_PKEY_sign_raw and EVP_PKEY_verify_raw functions did not call free to clean the memory. Consequently, the memory leaked and has not been recovered. With this updated, the EVP_PKEY_sign_raw and EVP_PKEY_verify_raw functions now call free and memory is not leaking. Bugzilla:2132767 golang now supports 4096 bit keys in x509 FIPS mode Previously, golang did not support the 4096 bit keys in x509 FIPS mode. Consequently, when the user used 4096 bit keys the program crashed. With this update, golang now supports 4096 bit keys in x509 FIPS mode. Bugzilla:2132694 libffi can now probe for executable memory with SELinux enabled By default, libffi does not probe for executable memory when SELinux is enabled. As a consequence, programs which use libffi closures and fork() without immediately executing some other processes terminate unexpectedly when SELinux is enabled. With this update, libffi looks for a /etc/sysconfig/libffi-force-shared-memory-check-first file and, if it exists, probes for executable memory regardless of if SELinux is enabled. As a result, programs using libffi can safely fork() without crashing with SELinux enabled. Bugzilla:2014228 Implemented big endian support in OpenSSL bindings for golang Previously, the OpenSSL bindings for golang did not have support for big-endian, leading to potential issues with the conversion of BigInt values. As a result, the crypto routines were unable to perform this conversion. To fix this issue, big-endian support was implemented in the OpenSSL bindings for golang . As a result, conversions from BigInt are now successful, and the tests pass as expected. Bugzilla:2132419 8.11. Identity Management Authentication to external IdPs that require a client secret is now possible Previously, SSSD did not properly pass client secrets to external identity providers (IdPs). Consequently, authentication failed against external IdPs that you previously configured with the ipa idp-add --secret command to require a client secret. With this update, SSSD passes the client secret to the IdP and users can authenticate. Jira:RHELPLAN-148303 IdM now supports setting hostmasks for sudo rules using Ansible Previously, the ipa sudorule-add-host command allowed setting a hostmask to be used by the sudo rule, but this option was not present in the ansible-freeipa package. With this update, you can now use the ansible-freeipa hostmask variable to define a list of hostmasks to which a particular sudo rule, defined in Identity Management (IdM), applies. As a result, you can now automate setting host masks for IdM sudo rules with Ansible. Bugzilla:2127912 The scheduled time of the changelog compaction now works correctly Previously, when you configured a custom scheduled time for the changelog compaction, the server did not apply the new setting, and the changelog compaction could start during peak times. With this release, the server now correctly applies the custom time of the changelog compaction. Bugzilla:2130276 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. With the release of RHBA-2023:4525 , a case-sensitive comparison is replaced with a case-insensitive comparison that ignores the case of a character. As a result, IdM clients can now lookup users of an AD trusted domain, even if their usernames contain mixed case characters and they are configured with overrides in IdM. Jira:SSSD-6096 8.12. Graphics infrastructure Matrox G200e now works correctly with a VGA display Previously, your display might have shown no graphical output if you used the following system configuration: The Matrox G200e GPU A display connected over the VGA controller As a consequence, you could not use or install RHEL on this configuration. With this release, the problem has been fixed. As a result, RHEL boots and shows graphical output as expected. Bugzilla:2130159 8.13. The web console The web console NBDE binding steps now work also on volume groups with a root file system In RHEL 8.8.0, due to a bug in the code for determining whether or not the user was adding a Tang key to the root file system, the binding process in the web console crashed when there was no file system on the LUKS container at all. Because the web console displayed the error message TypeError: Qe(... ) is undefined after you had clicked the Trust key button in the Verify key dialog, you had to perform all the required steps in the command-line interface in the described scenario. With the release of the RHBA-2023:3829 advisory, the web console correctly handles additions of Tang keys to root file systems. As a result, the web console finishes all binding steps required for the automated unlocking of LUKS-encrypted volumes using Network-Bound Disk Encryption (NBDE) in various scenarios. Bugzilla:2212371 8.14. Red Hat Enterprise Linux system roles The nbde_client system role now correctly handles different names of clevis-luks-askpass The nbde_client system role has been updated to handle the systems on which the clevis-luks-askpass systemd unit has a different name. The role now correctly works with different names of clevis-luks-askpass on managed nodes, which requires unlocking also LUKS-encrypted volumes that mount late in the boot process. Bugzilla:2126960 The ha_cluster system role logs no longer display unencrypted passwords and secrets The ha_cluster system role accepts parameters that can be passwords or other secrets. Previously, some of the tasks would log their inputs and outputs. As a result, the role logs could contain unencrypted passwords and other secrets. With this update, the tasks have been changed to use the Ansible no_log: true directive and the task output is no longer displayed in the role logs. The ha_cluster system role logs no longer contain passwords and other secrets. While this update protects secure information, the role logs now provide less information that you can use when debugging your configuration. Bugzilla:2127497 Clusters configured with ha_cluster system role to use SBD and not start on boot now work correctly Previously, if a user configured a cluster using the ha_cluster system role to use SBD and not start on boot, then the SBD service was disabled and SBD did not start. With this fix, the SBD service is always enabled if a cluster is set to use SBD whether or not the cluster is configured to start on boot. Bugzilla:2153081 Setting stonith-watchdog-timeout property with the ha_cluster system role now works in a stopped cluster Previously, when you set the stonith-watchdog-timeout property with the ha_cluster system role in a stopped cluster, the property reverted to its value and the role failed. With this fix, configuring the stonith-watchdog-timeout property by using the ha_cluster system role works properly. Bugzilla:2167941 Enabling implicit files provider to fix rhel-system-roles SSSD configuration A disabled SSSD implicit files provider caused the rhel-system-roles modules to create an invalid System Security Services Daemon (SSSD) configuration. This update unconditionally enables the files provider and as a result, the SSSD configuration created by rhel-system-roles now works as expected. Bugzilla:2153080 Network traffic is now directed through the intended network interface when using initscripts with the networking RHEL system role Previously, when using the initscripts provider, the routing configuration for network connections did not specify the output device that the traffic should go through. Consequently, the kernel could use a different output device than the user intended. Now, if the network interface name is specified in the playbook for the connection, it is used as the output device in the route configuration file. This aligns the behavior with NetworkManager, which configures the output device in routes when activating profiles on devices. As a result, the users can ensure that the traffic is directed through the intended network interface. Bugzilla:2168733 The nbde_client_clevis role no longer reports traceback to users Previously, the nbde_client_clevis role sometimes failed in exception, causing a traceback and reporting sensitive data, such as the encryption_password field, back to the user. With this update, the role no longer reports sensitive data, only the appropriate error messages. Bugzilla:2162782 8.15. Virtualization System time on nested VMs now works reliably Previously, system time on nested virtual machines (VMs) in some cases desynchronised from the Level 0 and level 1 hosts. This also sometimes caused the nested VM to become unresponsive or terminate unexpectedly. With this update, the time handling code in the KVM host kernel code has been fixed, which prevents the described errors from occurring. Bugzilla:2151854 Network traffic performance in virtual machines is no longer reduced Previously, RHEL virtual machines had, in some cases, decreased performance when handling high levels of network traffic. The underlying code has been fixed and the network traffic performance is not affected anymore. Bugzilla:2069047 Virtual machines using memfd run as expected Previously, virtual machines (VMs) running on the 64-bit IBM Z processor architecture that used memfd to back memory with hugepages failed to run. With this update, the problem has been fixed and VMs using memfd can now be defined on the 64-bit IBM Z processor architecture. As a result, you can now run VMs which use memfd to back the memory with hugepages. Bugzilla:2117149 System time in VMs now synchronizes correctly with the host Previously, the KVM module performed the real-time clock (RTC) synchronization less frequently than intended. As a consequence, the system time in VMs hosted on RHEL 8 sometimes did not correctly reflect the system time on the host. This update fixes the RTC scheduling in KVM, which prevents the described problem from occurring. Bugzilla:2135417
