OSG 23 News

Supported OS Versions: EL8, EL9 (see this document for details)

OSG 23 is the first release series that follows our new support policy, which aims to increase the regularity of the OSG Software Stack lifecycle. Moving forward, we plan to distribute a new release series each year, supporting each release series for approximately 2 years total. As with OSG 3.6, we will continue to release OSG 23 package updates in a rolling fashion.

Additionally, OSG 23 aligns the OSG and HTCondor Software Suite (HTCSS) release cycles:

  • OSG 23 main Yum repositories will contain HTCSS LTS series (HTCondor 23.0, HTCondor-CE 23.0)
  • OSG 23 upcoming Yum repositories will contain HTCSS feature series (HTCondor 23.x, HTCondor-CE 23.x)

Known Issues

The following issues are known to currently affect packages distributed in OSG 23:

CA Certificates on EL9

EL9 operating systems have a tighter default cryptographic policy that can cause services to reject certificates issued by SHA-1 signed CAs. Some CAs in the igtf-ca-certs and osg-ca-certs packages are affected and you may see service issues if your server certificate or certificates presented by clients are issued by these CAs. The Software Team is investigating solutions but in the meantime, we recommend running the following command on XRootD hosts to accept certificates issued by SHA-1 signed CAs:

root@host # update-crypto-policies --set DEFAULT:SHA1

Do I need to run this on my Compute Entrypoint (CE) hosts?

No. At this time, the Software Team believes that CE hosts are unaffected since their clients only present tokens and token issuers present modern CAs.

October 3, 2023: Initial Release

OSG 3.6 retirement

As part of our transition to our new series release cadence, we are planning to end support for OSG 3.6 on 30 June 2024 to align with the EL7 end-of-life. See our release series life-cycle table for details.

The initial release of OSG 23 contains major package updates, package removals, and new container images. All other packages may have received minor version and/or packaging updates compared to OSG 3.6.

Major package updates

This release contains the following major package updates compared to the current OSG 3.6 release:

  • HTCondor 23.0.0: an update from 10.0.8 in OSG 3.6 main and 10.8.0 in OSG 3.6 upcoming.

    • New features
      • A condor_startd without any slot types defined will now default to a single partitionable slot rather than a number of static slots equal to the number of cores as it was in previous versions. The configuration template use FEATURE : StaticSlots was added for admins wanting the old behavior.
      • The TargetType attribute is no longer a required attribute in most Classads. It is still used for queries to the condor_collector and it remains in the Job ClassAd and the Machine ClassAd because of older versions of HTCondor require it to be present.
      • The -dry-run option of condor_submit will now print the output of a SEC_CREDENTIAL_STORER script. This can be useful when developing such a script.
      • Added ability to query epoch history records from the python bindings.
      • The default value of SEC_DEFAULT_AUTHENTICATION_METHODS will now be visible in condor_config_val. The default for SEC_*_AUTHENTICATION_METHODS will inherit from this value, and thus no READ and CLIENT will no longer automatically have CLAIMTOBE.
      • Added new tool condor_test_token, which will create a SciToken with configurable contents (including issuer) which will be accepted for a short period of time by the local HTCondor daemons.
    • Bug fixes
      • Fixed a bug that would cause the condor_startd to crash in rare cases when jobs go on hold
      • Fixed a bug where if a user-level checkpoint could not be transferred from the starter to the AP, the job would go on hold Now it will retry, or go back to idle
      • Fixed a bug where the CommittedTime attribute was not set correctly for Docker Universe jobs doing user level check-pointing
      • Fixed a bug where condor_preen was deleting files named 'OfflineAds' in the spool directory
      • Fixed a bug where the blahpd would incorrectly believe that an LSF batch scheduler was not working
      • Fixed the Execution Point’s detection of whether libvirt is working properly for the VM universe
      • Fixed a bug where container universe did not work for late materialization jobs submitted to the condor_schedd
      • Fixed a bug where the condor_startd could crash if a new match is made at the end a drain request
  • HTCondor-CE 23.0.0: an update from 6.0.0 in OSG 3.6 main.

    Job router configuration deprecation

    The configuration macros JOB_ROUTER_DEFAULTS, JOB_ROUTER_ENTRIES, JOB_ROUTER_ENTRIES_CMD, and JOB_ROUTER_ENTRIES_FILE are deprecated and will be removed for V24 of HTCondor. New configuration syntax for the job router is defined using JOB_ROUTER_ROUTE_NAMES and JOB_ROUTER_ROUTE_<name>. Note: The removal will occur during the lifetime of the HTCondor V23 feature series, i.e. the versions that will be available in OSG upcoming repositories.

    • Adds deprecation warnings for old job router configuration syntax
    • Adds grid CA and host certificate/key locations to default SSL search paths
    • Verifies that HTCondor-CE can access the local HTCondor's SPOOL directory on startup
    • condor_ce_upgrade_check checks compatibility with HTCondor 23
    • Adds an option to allow running condor_ce_trace without a SciToken for testing batch system integration
  • XRootD 5.6.2: an update from XRootD 5.5.5 in OSG 3.6 main.

    • New Features
      • Add xrdfs cache subcommand to allow for cache evictions
      • Better handling of unicode strings in the API
      • Add gsi option to display DN when it differs from entity name
      • Allow specfication of minimum and maximum creation mode
      • Make maxfd be configurable (default is 256k)
      • Include token information in the monitoring stream (phase 1)
      • Implement a file evict function
      • Increase default number of parallel event loops to 10
      • xrdcp: number of parallel copy jobs increased from 4 to 128
      • Allow XRootD to return trailers indicating failure
      • Denote Accept-Ranges in HEAD response
      • Report cache object age for caching proxy mode
      • Allow origin to be a directory of a locally mounted file system
      • Implement ability to have the token username as a separate claim
      • Use SHA-256 for signatures, and message digest algorithm
      • Allow option '-tokenlib none' to disable token validation
      • Allow to point to a token file using CGI '?xrd.ztn=tokenfile'
    • Major bug fixes
      • Fix SEGV in case request has object for opaque data but no content
      • Fix memory leaks in GSI authentication
      • Fix chunked PUT creating empty files
  • GlideinWMS 3.10.5: an update from 3.10.1 in OSG 3.6 main

    If you are using custom setup scripts...

    If you are using custom setup scripts please change the use of glidein_config:

    • Custom scripts should always read values via gconfig_get(). The only exception is the parsing of the line to get the add_config_line source file.
    • add_config_line is deprecated in favor of gconfig_add. add_config_line will be removed from future versions.
    • add_config_line_safe is deprecated in favor of gconfig_add_safe. gconfig_add is the recommended method to use also in concurrent scripts.
    • Custom scripts in Python should import (compatible with both Python 2 and 3) and use the provided functions or classes: gconfig_get, gconfig_add, etc.
    • This release completes EL9 and Python 3.9 support
    • Added structured logging
    • Various OSG_Autoconf improvements
    • Fixed bugs with Python 3.9 and rrdtools failures with missing ClassAds and monitoring

Package Removals

The following packages were removed from OSG 23 compared to OSG 3.6:

  • blahp: available as part of the condor package
  • oidc-agent: available in EPEL
  • python-jwt: available in EPEL
  • python-scitokens: available in EPEL
  • rrdtool available from OS repositories

Container Images

The following container images have new tags for OSG 23:

Image name Tags 23-release, 23-testing 23-release, 23-testing 23-release, 23-testing 23-release, 23-testing 23-release, 23-testing 23-release, 23-testing 23-release, 23-testing

For example, to retreive an OSG 23 backfill container image, run the following command:

docker pull
