Enterprise Server 3.9 release notes

LOW: Due to an incorrect permission assignment for some configuration files, an attacker with access to a local operating system user account could read MySQL connection details including the MySQL password. [Updated: 2023-11-13]

Packages have been updated to the latest security versions.

The ghe-cluster-repl-status command did not display all replication statuses.

On an instance in a cluster configuration with high availability enabled, ghe-config-apply timed out while waiting for hookshot-go to start on replica application nodes.

SpokesRepairRepoReplicaJob and SpokesSyncCacheReplicaJob jobs failed, causing cache server replicas to not update and potentially prolonging replication issues.

/var/log/lastlog was not copied over as a sparse file during ghe-upgrade, which could cause issues by using additional disk space.

On an instance in a cluster configuration, when managing maintenance mode using ghe-cluster-maintenance, an erroneous warning appeared that read "Warning: Maintenance mode set on primary, please make sure to set it on any active replica if needed". - | ghe-repl-status did not identify Git replicas in certain incomplete states and incorrectly suggested that a failover could be performed safely. In some cases, this led to data loss during failover.

Repository exports using ghe-migrator or the REST API's operation for organization migrations could fail when a large number of commit comments or long commit comments were present.

On an instance with a GitHub Advanced Security license and secret scanning enabled, secret scanning suggested incorrect filters when viewing both open and closed alerts.

On instances using the private beta of SCIM provisioning, some users were presented with a "single sign-in" hover card.

On an instance with multiple nodes, ghe-spokes status did not identify Git replicas in certain incomplete states, causing a false report that replication was in sync and leading to data loss or replication issues during failover.

On an instance with GitHub Actions enabled, administrators received a 500 error after attempting to force cancel a workflow run via Staff Tools.

On an instance with a GitHub Advanced Security license, repositories within organizations created using the + dropdown menu did not have GitHub Advanced Security features enabled automatically, even if the features should have been enabled.

As a security measure, GitHub Pages does not build sites that contain symbolic links except when using custom GitHub Actions workflows. This change strengthens GitHub Pages's symbolic link detection.

On an instance with a GitHub Advanced Security license and secret scanning enabled, dry runs sometimes incorrectly reported no results for custom patterns.

Instructions in the "Migrations" section of the Management Console clarify that only standard AWS S3 endpoints are supported when configuring AWS S3 as a blob storage provider for migrations.

When running async repository repairs, the output message about scheduling a repair job is more accurate.

On an instance in a cluster configuration, administrators can identify the repository networks or gists that are common across a specified set of storage nodes using the spokesctl find-on-replicas command.

In GitHub Enterprise Server 3.10 and later, the requirements for TLS security levels have changed due to an upgrade to containers in the underlying OS. After upgrading from GitHub Enterprise Server 3.9, on an instance with GitHub Actions enabled and a custom TLS certificate, users may experience disruptions with workflow runs if the TLS certificate uses weak encryption. Workflow runs will not trigger, and the following error message will appear in system logs for babeld.

CA certificate key too weak

To resolve this issue, confirm that your certificate complies with level 2 of the OpenSSL security specification. For more information, see SSL_CTX_set_security_level in the OpenSSL docs. For more information about reviewing your instance's logs, see "Informationen zu Systemprotokollen".

If the error appears in babeld logs because your TLS certificate does not comply with level 2 of the specification, you must create and upload a new certificate with stronger security before you upgrade to GitHub Enterprise Server 3.10 or later. For more information, see "TLS konfigurieren." [Updated: 2023-10-26]

Custom firewall rules are removed during the upgrade process.

During the validation phase of a configuration run, a No such object error may occur for the Notebook and Viewscreen services. This error can be ignored as the services should still correctly start.

If the root site administrator is locked out of the Management Console after failed login attempts, the account does not unlock automatically after the defined lockout time. Someone with administrative SSH access to the instance must unlock the account using the administrative shell. For more information, see "Problembehandlung beim Zugriff auf die Verwaltungskonsole."

On an instance in a high-availability configuration, passive replica nodes accept Git client requests and forward the requests to the primary node.

If an instance is configured to forward logs to a target server with TLS enabled, certificate authority (CA) bundles that a site administrator uploads using ghe-ssl-ca-certificate-install are not respected, and connections to the server fail.

When running ghe-config-apply, the process may stall with the message Deployment is running pending automatic promotion.

The mbind: Operation not permitted error in the /var/log/mysql/mysql.err file can be ignored. MySQL 8 does not gracefully handle when the CAP_SYS_NICE capability isn't required, and outputs an error instead of a warning.

On an instance with subdomain isolation disabled, Mermaid diagrams in the web UI display an "Unable to render rich display" error and fail to render.

When enabling CodeQL via default setup at scale, some checks related to GitHub Actions are omitted, potentially preventing the process from completing.

After an administrator upgrades from GitHub Enterprise Server 3.7 or 3.8, to 3.9 or 3.10, MySQL may not start back up. For more information, see "Bekannte Probleme mit Upgrades für deine Instanz." [Updated: 2023-08-11]

After an administrator upgrades from GitHub Enterprise Server 3.7 or 3.8 to 3.9 or 3.10, I/O utilization will increase, and in some cases the instance's performance will be impacted. Reduced performance is due to the database server being upgraded from MySQL 5.7 to MySQL 8.0. For more information, see "Bekannte Probleme mit Upgrades für deine Instanz."

In rare circumstances, a small instance with both high availability and GitHub Actions configured may report that MSSQL replication is unhealthy after many upgrades with full upgrade packages. If you encounter this issue, contact GitHub Support.

On an instance in a cluster configuration with high availability configured, ghe-config-apply times out while waiting for hookshot-go to start on replica application nodes.

Jobs in a deprecated queue are not processed and may accumulate over time. These jobs are reflected in the monitor dashboard's "Aqueduct queue depth" graph as an increase in resource_activity. In some cases, a buildup of unprocessed jobs can result in memory exhaustion. If you observe memory exhaustion on your instance and see a high metric for resource_activity, contact GitHub Support.

When an administrator uses the -p flag with the ghe-support-bundle utility to collect data for a specific number of hours, the utility erroneously collects more logs than necessary.

On an instance hosted in AWS, system time may lose synchronization with Amazon's servers after an administrator reboots the instance. [Updated 2023-11-10]

On an instance with GitHub Actions enabled, after an upgrade from GitHub Enterprise Server 3.8 or earlier, an internal exception could prevent successful completion of some operations, like upgrades or the configuration of new replica nodes for high availability. If this issue occurs, administrators may see the following error in /data/user/common/ghe-config.log.

For more information, see "Protokollweiterleitung" article

For an instance or organization with 2FA enabled, when a user sets up 2FA, GitHub Enterprise Server suggests an authenticator app (TOTP) by default.

When a person with administrative SSH access to an instance submits a support bundle using either the ghe-support-bundle or ghe-cluster-support-bundle utility, a period for log collection specified with the -p or --period no longer requires quotes to enclose the date value. For more information, see "Befehlszeilenprogramme."

To provide additional context within the web interface on an instance where Dependabot alerts are enabled, links to Dependabot alerts in an issue or pull request comment display an improved label and hovercard with alert details.

On an instance with Dependabot alerts enabled, people with write or maintain access to a repository can view or act on Dependabot alerts by default. Custom roles, the security manager role, organization permissions, and notification settings are not affected.

On an instance with a GitHub Advanced Security license and GitHub Connect enabled for the synchronization of actions from GitHub.com, CodeQL code scanning is up to 16% faster. For more information, see "Konfigurieren des Codescannings für deine Appliance."

On an instance with a GitHub Advanced Security license and email configured for notifications, users can receive notifications for secret scanning alerts by watching a repository and choosing "All activity" or "Security alerts". To continue receiving notifications for secret scanning alerts in GitHub Enterprise Server 3.9 and later, users must enable email notifications in the web interface at http(s)://HOSTNAME/settings/notifications under "Watching" by choosing "Email".

On an instance with a GitHub Advanced Security license, secret scanning alerts display whether detected tokens from GitHub are valid.

On an instance with a GitHub Advanced Security license, the enterprise and organization audit logs now display an event when an owner enables or disables a push protection for a custom pattern for a repository, organization, or the enterprise. For more information, see "Auditprotokoll deiner Organisation überprüfen" and "Überwachungsprotokollereignisse für Ihre Enterprise."

Users can filter the lists of alerts for Dependabot, code scanning, and secret scanning by repository topic or team in the security overview for an organization. For more information, see "Filtern von Warnungen in der Sicherheitsübersicht."

In the security overview for an organization, the following improvements apply to the "Security coverage" view during feature enablement.

• To provide insight into the number of GitHub Advanced Security licenses used, active committers for the repository are visible. For repositories where GitHub Advanced Security is not enabled, the number indicates the number of licenses required to enable the feature.
• Unsaved changes are now labeled with a "Modified" tag, and the "Save security settings" button now displays the total number of changes to save.
• While a security feature is being enabled, the "Security coverage" view shows a status of "Updating..." to inform you of the ongoing process.

For more information, see "Informationen zur Sicherheitsübersicht."

In the security overview's "Security risk" and "Security coverage" views, when a user selects a team from the "Team" drop-down or filters by team, results appear for repositories where the team has write or administrative access or has been granted access to security alerts. Previously, users could only view results for repositories where the team had administrative access or had been granted access to security alerts.

To provide more context within a project, users can share a deep link to a specific issue in a project to have the issue open in the project's side panel.

Organization owners can create up to five custom repository roles. Previously, the limit was three. For more information, see "Informationen zu benutzerdefinierten Repositoryrollen."

When transferring a repository, users can also rename the repository. For more information, see "Repository übertragen."

If a user archives a repository, responses from the GraphQL API that include information about the repository now include an archivedAt value with a timestamp representing the archival date.

Before beginning a backup with GitHub Enterprise Server Backup Utilities 3.9.0 and later, the ghe-host-check utility will now perform a preflight check on the backup host to confirm the software version and disk space requirements. For more information, see the 3.9.0 release in the github/backup-utils repository on GitHub.com.

GitHub Enterprise Server Backup Utilities 3.9.0 allows administrators to view the progress of backup and restoration operations on the backup host using the ghe-backup-progress utility. For more information, see "Konfigurieren von Sicherungen auf einer Instanz."

After an administrator upgrades from GitHub Enterprise Server 3.7 or 3.8 to 3.9 or 3.10, I/O utilization will increase, and in some cases the instance's performance will be impacted. Reduced performance is due to the database server being upgraded from MySQL 5.7 to MySQL 8.0. For more information, see "Bekannte Probleme mit Upgrades für deine Instanz."

After an administrator upgrades from GitHub Enterprise Server 3.7 or 3.8, to 3.9 or 3.10, MySQL may not start back up. For more information, see "Bekannte Probleme mit Upgrades für deine Instanz." [Updated: 2023-08-11]

In GitHub Enterprise Server 3.10 and later, the requirements for TLS security levels have changed due to an upgrade to containers in the underlying OS. After upgrading from GitHub Enterprise Server 3.9, on an instance with GitHub Actions enabled and a custom TLS certificate, users may experience disruptions with workflow runs if the TLS certificate uses weak encryption. Workflow runs will not trigger, and the following error message will appear in system logs for babeld.

CA certificate key too weak

To resolve this issue, confirm that your certificate complies with level 2 of the OpenSSL security specification. For more information, see SSL_CTX_set_security_level in the OpenSSL docs. For more information about reviewing your instance's logs, see "Informationen zu Systemprotokollen".

If the error appears in babeld logs because your TLS certificate does not comply with level 2 of the specification, you must create and upload a new certificate with stronger security before you upgrade to GitHub Enterprise Server 3.10 or later. For more information, see "TLS konfigurieren." [Updated: 2023-10-26]

The Management Console may get stuck in a loop showing "Checking requirements..." when attempting to download an update. It is safe to proceed the update process manually via the command line.

After restoration of a backup created using GitHub Enterprise Server Backup Utilities 3.7.0, 3.8.0, or 3.9.0, users may not be able to sign into the instance. To fix this issue, plus a bug that was preventing secret scanning encryption keys from being backed up, upgrade your backup host to use GitHub Enterprise Server Backup Utilities 3.9.1 and generate a new full backup using ghe-backup. For more information on using an existing backup, see "Bekannte Probleme mit Sicherungen für Instanzen." [Updated: 2023-07-31]

After upgrading an existing instance to GitHub Enterprise Server 3.9, the Manage GitHub Enterprise Server API is unavailable. To enable the API, SSH into the instance and run the following commands.

sudo mkdir -p /data/ghes-manage-gateway/current
sudo chown -R ghes-manage-gateway:ghes-manage-gateway /data/ghes-manage-gateway/current
sudo systemctl restart ghes-manage-gateway ghes-manage-gateway-consul

sudo mkdir -p /data/ghes-manage-gateway/current
sudo chown -R ghes-manage-gateway:ghes-manage-gateway /data/ghes-manage-gateway/current
sudo systemctl restart ghes-manage-gateway ghes-manage-gateway-consul

For more information about the Manage GitHub Enterprise Server API, see "Manage GitHub Enterprise Server" in the REST API documentation. [Updated: 2023-06-22]

On an instance in a cluster configuration, after you upgrade nodes other than the primary MySQL node and before you upgrade the primary MySQL node, the following output may appear multiple times after you run ghe-config-apply.

Error response from daemon: conflict: unable to delete IMAGE_ID (cannot be forced) - image is being used by running container CONTAINER_ID

You can safely ignore this message.

Custom firewall rules are removed during the upgrade process.

On an instance in a high-availability configuration, passive replica nodes accept Git client requests and forward the requests to the primary node.

The mbind: Operation not permitted error in the /var/log/mysql/mysql.err file can be ignored. MySQL 8 does not gracefully handle when the CAP_SYS_NICE capability isn't required, and outputs an error instead of a warning.

When using an outbound web proxy server, the ghe-btop command may fail in some circumstances with the error "Error querying allocation: Unexpected response code: 401".

If an instance is configured to forward logs to a target server with TLS enabled, certificate authority (CA) bundles that a site administrator uploads using ghe-ssl-ca-certificate-install are not respected, and connections to the server fail.

When running ghe-config-apply, the process may stall with the message Deployment is running pending automatic promotion.

During the validation phase of a configuration run, a No such object error may occur for the Notebook and Viewscreen services. This error can be ignored as the services should still correctly start.

If the root site administrator is locked out of the Management Console after failed login attempts, the account will not unlock automatically after the defined lockout time. Someone with administrative SSH access to the instance must unlock the account using the administrative shell. For more information, see "Problembehandlung beim Zugriff auf die Verwaltungskonsole."

On an instance with subdomain isolation disabled, Mermaid diagrams in the web UI display an "Unable to render rich display" error and fail to render. [Updated: 2023-08-18]

In rare circumstances, a small instance with both high availability and GitHub Actions configured may report that MSSQL replication is unhealthy after many upgrades with full upgrade packages. If you encounter this issue, contact GitHub Support. [Updated: 2023-08-24]

On an instance with GitHub Actions enabled, if shared runner groups are configured for the enterprise, the enterprise security overview page may return a 500 error. You can avoid the issue by trying one of the following workarounds.

• Add a runner scale set to the enterprise runner group shared with the repositories.
• Remove access to the enterprise runner group from the affected repositories or organizations.

[Updated: 2023-09-05]

On an instance in a cluster configuration with high availability configured, ghe-config-apply times out while waiting for hookshot-go to start on replica application nodes. [Updated: 2023-09-21]

On an instance with GitHub Actions enabled, ephemeral self-hosted runners do not automatically update to the latest version. Users will need to manually update the runners to the latest version. [Updated: 2023-09-29]

Jobs in a deprecated queue are not processed and may accumulate over time. These jobs are reflected in the monitor dashboard's "Aqueduct queue depth" graph as an increase in resource_activity. In some cases, a buildup of unprocessed jobs can result in memory exhaustion. If you observe memory exhaustion on your instance and see a high metric for resource_activity, contact GitHub Support. [Updated: 2023-10-10]

When an administrator uses the -p flag with the ghe-support-bundle utility to collect data for a specific number of hours, the utility erroneously collects more logs than necessary. [Updated: 2023-10-13]

The settings for enabling scheduled reminders were added unintentionally to this release. Scheduled reminders are not officially supported. [Updated: 2023-10-17]

On an instance with GitHub Actions enabled, after an upgrade from GitHub Enterprise Server 3.8 or earlier, an internal exception could prevent successful completion of some operations, like upgrades or the configuration of new replica nodes for high availability. If this issue occurs, administrators may see the following error in /data/user/common/ghe-config.log.

Error occurred while executing servicing step 'Clone datatier login to secondary replica' for component CopyAvailabilityGroupSqlLogins during CopyAvailabilityGroupSqlLogins: Object reference not set to an instance of an object.

To resolve this issue, upgrade to the latest patch release of GitHub Enterprise Server. [Updated: 2023-12-04]

On an instance hosted in AWS, system time may lose synchronization with Amazon's servers after an administrator reboots the instance. [Updated 2023-11-10]

On an instance in a cluster configuration, restoration of a backup using ghe-restore will exit prematurely if Redis has not restarted properly. [Updated 2023-12-05]

Change to command-line utility for management of replication

• On an instance with multiple nodes, people with administrative SSH access to the instance should use ghe-spokesctl for management of Git replication instead of ghe-spokes. For more information, see "Befehlszeilenprogramme."

Dependency graph no longer ingests go.sum files

• Because go.sum files are not lock files and may result in false positive Dependabot alerts, on an instance with the dependency graph enabled, the go.sum files are no longer ingested for users' Go repositories. If Dependabot alerts are enabled, Dependabot will no longer alert users for vulnerabilities in a go.sum file's dependencies. The dependency graph continues to support go.mod files, the recommended format for Go projects. Use Go 1.17 or higher to ensure your go.mod file contains a comprehensive view of all direct and transitive dependencies. For more information, see "Informationen zum Abhängigkeitsdiagramm."

Only GitHub Actions can publish a GitHub Pages site if source includes symbolic links

• To improve the security of an instance where users deploy sites using GitHub Pages, sites that contain symbolic links will no longer build outside of GitHub Actions. If a user's site is affected and a site administrator has configured email for the instance, the user will receive an email with instructions about how to fix the error. To continue using symbolic links in the site's source, the instance must be configured for GitHub Actions, and the user must write a GitHub Actions workflow to use as a publishing source. For more information, see "Informationen zu GitHub Pages."
