Prerequisites

Consider the following requirements for your system:

Talend Jobserver 7.3.1 must be installed.

General patch installation

Create a backup of the files in <jobserver_home>/lib, <jobserver_home>/conf and the *.bat and *.sh scripts.
Stop Jobserver.
Remove all files from <jobserver_home>/lib, <jobserver_home>/*.sh and <jobserver_home>/*.bat .
Replace them with their patched counterparts.

Recommended change of following configuration properties in <jobserver_home>/conf/TalendJobserver.properties in case you use SSL:

# Enabled protocols for JobServer socket communication
org.talend.remote.server.ssl.enabled.protocols=TLSv1.2,TLSv1.3

# Enabled protocols for JMX management server
org.talend.jmxmp.ssl.enabled.protocols=TLSv1.2,TLSv1.3

Recommended to set following configuration property to false in case you want to disable the Monitoring Port 8888:

# Enable the Monitoring port or not. true by default
org.talend.remote.jobserver.server.TalendJobServer.ENABLE_MONITORING_PORT=true

Add the following new configuration properties to <jobserver_home>/conf/TalendJobserver.properties:

# Set to retrieve the job table after restart to avoid redeployment of already deployed jobs
org.talend.remote.jobserver.commons.config.JobServerConfiguration.RESTORE_JOBTABLE=true

# Set to true to unescape context parameters. 
org.talend.remote.jobserver.commons.config.JobServerConfiguration.UNESCAPE_CONTEXTS=true

# Max size in bytes that an unzipped archive is allowed to be. The default is 1G.
org.talend.remote.jobserver.commons.config.JobServerConfiguration.MAX_UNZIPPED_SIZE=1073741824
# Max number of entries allowed in a zipped archive
org.talend.remote.jobserver.commons.config.JobServerConfiguration.MAX_ZIPPED_ENTRIES=2048

If your server side SSL keys are protected by passwords different from the keystore password, you can configure those with the following settings:

# Set password of server side ssl key (command and file server) - optional
org.talend.remote.server.ssl.keyPassword=<jobserver_key_password>

# Set password of server side ssl key (monitoring server) - optional
org.talend.jmxmp.ssl.keyPassword=<monitoring_server_key_password>

It is recommended to set the following configuration property to true:

# Set to true to enable authorization for all jobserver commands (recommended)
org.talend.remote.jobserver.commons.config.JobServerConfiguration.SECURITY_MODE=true

New possibility to disable hostname configuration for the TACClient:

# Set this to true to disable hostname verification for the TACClient
#org.talend.remote.jobserver.commons.config.JobServerConfiguration.TLS_DISABLE_CN_CHECK=true

The following configuration property enables authorization for all job file deployments. This requires that on client-side ( TAC, Studio ) support for file server authorization must be available and the system property org.talend.remote.jobserver.client.old has be set to false. For more details refer to the documentation.

# Set to true to enable authorization for all job file deployments
( Requires additional configuration for TAC and Studio. )
org.talend.remote.jobserver.commons.config.JobServerConfiguration.FILESERVER_AUTHORIZATION=true

The following configuration have been added to add constraints on job to prevent Denial Of Service attacks. High default have been defined, it is recommended to adapt these to your environment.

# Maximum number of file listeners, 0 = No limit
org.talend.remote.jobserver.commons.config.JobServerConfiguration.MAX_FILE_LISTENERS=6000

# Maximum number of library dependencies embedded in a job
org.talend.remote.jobserver.commons.config.JobServerConfiguration.MAX_LIBRARY_DESC_NB=1000
# Maximum size of all library dependency names for a job
org.talend.remote.jobserver.commons.config.JobServerConfiguration.MAX_LIBRARY_DESC_SIZE=100KB

# Maximum number of deployed jobs, 0 = No Limit
org.talend.remote.jobserver.commons.config.JobServerConfiguration.MAX_JOB_NB=6000

# Max size that a job archive is allowed to be. The default is 1G, 0 = No limit
org.talend.remote.jobserver.commons.config.JobServerConfiguration.MAX_JOB_FILE_SIZE=1G

# Maximum size of TalendJobServersFiles/archiveJobs folder, 0 = No limit, 0 = No Limit
org.talend.remote.jobserver.commons.config.JobServerConfiguration.MAX_ARCHIVES_DIR_SIZE=100G

The following configuration have been added to activate job archive signature check.

 # Activate job archive signature, 1 or more values separated by comma (',').
 # Possible values are:
 # - 'ON_DEPLOY' (legacy)
 # - 'ON_UPLOAD' (advised & default)
 org.talend.remote.jobserver.commons.config.JobServerConfiguration.JOB_ARCHIVE_SIGNATURE_CHECK=ON_UPLOAD

An empty allow list for impersonation users is not supported anymore. If you want to allow impersonation for anyone and support jobs running without impersonation, you need to explicitly set:
```
org.talend.remote.jobserver.server.TalendJobServer.RUN_AS_ALLOWLIST=anybody
```
Please refer to the following examples to understand this setting:

RUNASALLOWLIST	Run as user	Execution	Explanation
		accepted	No impersonation, OK
anybody		accepted	No impersonation, OK
anybody	jim	accepted	All users allowed
*		refused	Must specify a user
*	jim	accepted	All users allowed
jim,jules		refused	Must specify a user from the list
jim,jules	jim	accepted	jim is in the list
ju*	jules	accepted	jules matches ju*

Check Read, Write & Execution rights on files

Per default, the rights should be: - `rw-r--r--` (i.e. `0664`) per default, meaning everybody can read, but only the owner can overwrite the file - `rwxr-xr-x` (i.e. `0655`) for *.sh files, meaning everybody can read & execute, but only the owner can overwrite the file If needed, feel free to update these rights to match your current installation environment. Especially to allow further patch updates by a non-owner user, you might want to allow other users to have Write access.

Start Jobserver

Updates of installation of the Windows Service

This requires that the general patch installation ( which also includes the backup of wrapper.conf modified here ) has been performed already.

Stop the Windows Service
Adapt the wrapper.conf configuration file wrapper.java.classpath.<xx> entries to point to the jar files patched with this fix in <jobserver_home>/lib .
Remove entries no longer in <jobserver_home>/lib .

Rollback of patch installation

( Includes changes possibly done for JobServer running as Windows service. )

Stop Jobserver.
Remove the files in <jobserver_home>/lib, <jobserver_home>/conf and the *.bat and *.sh scripts. and restore the unpatched counterparts from your backup.
Start Jobserver

Affected files for this patch

All files in <jobserver_home>/lib, <jobserver_home>/conf and the *.bat and *.sh scripts.

Removed features

TPRUN-3775

When the option org.talend.remote.jobserver.commons.config.JobServerConfiguration.LAUNCH_SHELL_SCRIPT was set to false (which is the default value), the script files were regenerated in :

deployedJobPath/[jobName]/[jobName]_run.bat for Windows
deployedJobPath/[jobName]/[jobName]_run.sh for UNIX

These files will no longer be regenerated ( updated with valid classpath ) and thus will not be executable anymore. To see executed command please use the debug level log.

Deprecated features

TPRUN-3775

The possibility to launch from shell script using option org.talend.remote.jobserver.commons.config.JobServerConfiguration.LAUNCH_SHELL_SCRIPT set to true is deprecated and will be removed in end 2022.
