> * Changes in Slurm 23.02.1
> ==========================
> -- job_container/tmpfs - cleanup job container even if namespace mount is
> already unmounted.
> -- When cluster specific tables are be removed also remove the job_env_table
> and job_script_table.
> -- Fix the way bf_max_job_test is applied to job arrays in backfill.
> -- data_parser/v0.0.39 - Avoid dumping -1 value or NULL when step's
> consumed_energy is unset.
> -- scontrol - Fix showing Array Job Steps.
> -- scontrol - Fix showing Job HetStep.
> -- openapi/dbv0.0.38 - Fix not displaying an error when updating QOS or
> associations fails.
> -- data_parser/v0.0.39 - Avoid crash while parsing composite structures.
> -- sched/backfill - fix deleted planned node staying in planned node bitmap.
> -- Fix nodes remaining as PLANNED after slurmctld save state recovery.
> -- Fix parsing of cgroup.controllers file with a blank line at the end.
> -- Add cgroup.conf EnableControllers option for cgroup/v2.
> -- Get correct cgroup root to allow slurmd to run in containers like Docker.
> -- Fix "(null)" cluster name in SLURM_WORKING_CLUSTER env.
> -- slurmctld - add missing PrivateData=jobs check to step ContainerID lookup
> requests originated from 'scontrol show step container-id=<id>' or certain
> scrun operations when container state can't be directly queried.
> -- Automatically sort the TaskPlugin list reverse-alphabetically. This
> addresses an issue where cpu masks were reset if task/affinity was listed
> before task/cgroup on cgroup/v2 systems with Linux kernel < 6.2.
> -- Fix some failed terminate job requests from a 23.02 slurmctld to a 22.05 or
> 21.08 slurmd.
> -- Fix compile issues on 32-bit systems.
> -- Fix nodes un-draining after being drained due to unkillable step.
> -- Fix remote licenses allowed percentages reset to 0 during upgrade.
> -- sacct - Avoid truncating time strings when using SLURM_TIME_FORMAT with
> the --parsable option.
> -- data_parser/v0.0.39 - fix segfault when default qos is not set.
> -- Fix regression in 22.05.0rc1 that broke Nodes=ALL in a NodeSet.
> -- openapi/v0.0.39 - fix jobs submitted via slurmrestd being allocated fewer
> CPUs than tasks when requesting multiple tasks.
> -- Fix job not being scheduled on valid nodes and potentially being rejected
> when using parentheses at the beginning of square brackets in a feature
> request, for example: "feat1&[(feat2|feat3)]".
> -- Fix a job being scheduled on nodes that do not match a feature request that
> uses parentheses inside of brackets and requests additional features outside
> of brackets, for example: "feat1&[feat2|(feat3|feat4)]".
> -- Fix regression in 23.02.0rc1 which made --gres-flags=enforce-binding no
> longer enforce optimal core-gpu job placement.
> -- switch/hpe_slingshot - add option to disable VNI allocation per-job.
> -- switch/hpe_slingshot - restrict CXI services to the requesting user.
> -- switch/hpe_slingshot - Only output tcs once in SLINGSHOT_TCS env.
> -- switch/hpe_slingshot - Fix updating LEs and ACs limits.
> -- switch/hpe_slingshot - Use correct Max for EQs and CTs.
> -- switch/hpe_slingshot - support configuring network options per-job.
> -- switch/hpe_slingshot - retry destroying CXI service if necessary.
> -- Fix memory leak caused by job preemption when licenses are configured.
> -- mpi/pmix - Fix v5 to load correctly when libpmix.so isn't in the normal
> lib path.
> -- data_parser/v0.0.39 - fix regression where "memory_per_node" would be
> rejected for job submission.
> -- data_parser/v0.0.39 - fix regression where "memory_per_cpu" would be
> rejected for job submission.
> -- slurmctld - add an assert to check for magic number presence before deleting
> a partition record and clear the magic afterwards to better diagnose
> potential memory problems.
> -- Clean up OCI containers task directories correctly.
> -- slurm.spec - add "--with jwt" option.
> -- scrun - Run under existing job when SLURM_JOB_ID is present.
> -- Prevent a slurmstepd crash when the I/O subsystem has hung.
> -- common/conmgr - fix memory leak of complete connection list.
> -- data_parser/v0.0.39 - fix memory leak when parsing every field in a struct.
> -- job_container/tmpfs - avoid printing extraneous error messages when running
> a spank plugin that implements slurm_spank_job_prolog() or
> slurm_spank_job_epilog().
> -- Fix srun < 23.02 always getting an "exact" core allocation.
> -- Prevent scontrol < 23.02 from setting MaxCPUsPerSocket to 0.
