Slurm versions 24.05.2, 23.11.9, and 23.02.8 are now available (security fix for switch plugins)
by Tim Wickberg 31 Jul '24

31 Jul '24

Slurm versions 24.05.2, 23.11.9, and 23.02.8 are now available and include a fix for a recently discovered security issue with the switch plugins. SchedMD customers were informed on July 17th and provided a patch on request; this process is documented in our security policy. [1] For the switch/hpe_slingshot and switch/nvidia_imex plugins, a user could override the isolation between Slingshot VNIs or IMEX channels. If you do not have one of these switch plugins configured, then you are not impacted by this issue. It is unclear what, if any, information could be accessed with access to an unauthorized channel. This disclosure is being made out of an abundance of caution. If you do have one of these plugins enabled, the slurmctld must be restarted before the slurmd daemons to avoid disruption. Downloads are available at https://www.schedmd.com/downloads.php .

Slurm version 23.11.6 is now available
by Marshall Garey 16 Apr '24

16 Apr '24

We are pleased to announce the availability of Slurm version 23.11.6. The 23.11.6 release includes two different problems with the priority/multifactor plugin: a crash and a miscalculation of AssocGrpCPURunMinutes after a slurmctld reconfiguration/restart. The wsrep_on errors that sites running MySQL or older MariaDB should happen much less frequently and has a clarifying statement when it is an innocuous error. Slurm can be downloaded from https://www.schedmd.com/downloads.php . -Marshall > * Changes in Slurm 23.11.6 > ========================== > -- Avoid limiting sockets per node to one when using gres enforce-binding. > -- slurmrestd - Avoid permission denied errors when attempting to listen on > the same port multiple times. > -- Fix GRES reservations where the GRES has no topology > (no cores= in gres.conf). > -- Ensure that thread_id_rpc is gone before priority_g_fini(). > -- Fix scontrol reboot timeout removing drain state from nodes. > -- squeue - Print header on empty reponse to `--only-job-state`. > -- Fix slurmrestd not ending job properly when xauth is not present and a x11 > job is sent. > -- Add experimental job state caching with > SchedulerParameters=enable_job_state_cache to speed up querying job states > with squeue --only-job-state. > -- slurmrestd - Correct dumping of invalid ArrayJobIds returned from > 'GET /slurm/v0.0.40/jobs/state'. > -- squeue - Correct dumping of invalid ArrayJobIds returned from > `squeue --only-job-state --{json|yaml}`. > -- If scancel --ctld is not used with --interactive, --sibling, or specific > step ids, then this option issues a single request to the slurmctld to > signal all jobs matching the specified filters. This greatly improves > the performance of slurmctld and scancel.

This could happen if a multi-partition > job doesn't specify --exclusive and is evaluated first on a partition > configured with OverSubscribe=EXCLUSIVE but ends up starting in a partition > configured with OverSubscribe!=EXCLUSIVE evaluated afterwards. > -- Setting GLOB_SILENCE flag no longer exposes old bugged behavior. > -- Fix associations AssocGrpCPURunMinutes being incorrectly computed for > running jobs after a controller reconfiguration/restart. > -- Fix scheduling jobs that request --gpus and nodes have different node > weights and different numbers of gpus. > -- slurmrestd - Add "NO_CRON_JOBS" as possible flag value to the following: > 'DELETE /slurm/v0.0.40/jobs' flags field. > 'DELETE /slurm/v0.0.40/job/{job_id}?flags=' flags query parameter. > -- Fix scontrol segfault/assert failure if the TRESPerNode parameter is used > when creating reservations. > -- Avoid checking for wsrep_on when restoring streaming replication settings. > -- Clarify in the logs that error "1193 Unknown system variable 'wsrep_on'" is > innocuous. > -- accounting_storage/mysql - Fix problem when loading reservations from an > archive dump. > -- slurmdbd - Fix minor race condition when sending updates to a shutdown > slurmctld. > -- slurmctld - Fix invalid refusal of a reservation update. > -- openapi - Fix memory leak of /meta/slurm/cluster response field. > -- Fix memory leak when using auth/slurm and AuthInfo=use_client_ids. -- Marshall Garey Release Management, Support, and Development SchedMD LLC - Commercial Slurm Development and Support
