[slurm-announce] Slurm version 22.05.6 is now available

[Marshall Garey]

We are pleased to announce the availability of Slurm version 22.05.6.

This includes a fix to core selection for steps which could result in 
random task launch failures, alongside a number of other moderate 
severity issues.

> * Changes in Slurm 22.05.6
> ==========================
>  -- Fix a partition's DisableRootJobs=no from preventing root jobs from working.
>  -- Fix the number of allocated cpus for an auto-adjustment case in which the
>     job requests --ntasks-per-node and --mem (per-node) but the limit is
>     MaxMemPerCPU.
>  -- Fix POWER_DOWN_FORCE request leaving node in completing state.
>  -- Do not count magnetic reservation queue records towards backfill limits.
>  -- Clarify error message when --send-libs=yes or BcastParameters=send_libs
>     fails to identify shared library files, and avoid creating an empty
>     "<filename>_libs" directory on the target filesystem.
>  -- Fix missing CoreSpec on dynamic nodes upon slurmctld restart.
>  -- Fix node state reporting when using specialized cores.
>  -- Fix number of CPUs allocated if --cpus-per-gpu used.
>  -- Add flag ignore_prefer_validation to not validate --prefer on a job.
>  -- Fix salloc/sbatch SLURM_TASKS_PER_NODE output environment variable when the
>     number of tasks is not requested.
>  -- Permit using wildcard magic cookies with X11 forwarding.
>  -- cgroup/v2 - Add check for swap when running OOM check after task
>     termination.
>  -- Fix deadlock caused by race condition when disabling power save with a
>     reconfigure.
>  -- Fix memory leak in the dbd when container is sent to the database.
>  -- openapi/dbv0.0.38 - correct dbv0.0.38_tres_info.
>  -- Fix node SuspendTime, SuspendTimeout, ResumeTimeout being updated after
>     altering partition node lists with scontrol.
>  -- jobcomp/elasticsearch - fix data_t memory leak after serialization.
>  -- Fix issue where '*' wasn't accepted in gpu/cpu bind.
>  -- Fix SLURM_GPUS_ON_NODE for shared GPU gres (MPS, shards).
>  -- Add SLURM_SHARDS_ON_NODE environment variable for shards.
>  -- Fix srun error with overcommit.
>  -- Fix bug in core selection for the default cyclic distribution of tasks
>     across sockets, that resulted in random task launch failures.
>  -- Fix core selection for steps requesting multiple tasks per core when
>     allocation contains more cores than required for step.
>  -- gpu/nvml - Fix MIG minor number generation when GPU minor number
>     (/dev/nvidia[minor_number]) and index (as seen in nvidia-smi) do not match.
>  -- Fix accrue time underflow errors after slurmctld reconfig or restart.
>  -- Surpress errant errors from prolog_complete about being unable to locate
>     "node:(null)".
>  -- Fix issue where shards were selected from multiple gpus and failed to
>     allocate.
>  -- Fix step cpu count calculation when using --ntasks-per-gpu=.
>  -- Fix overflow problems when validating array index parameters in slurmctld
>     and prevent a potential condition causing slurmctld to crash.
>  -- Remove dependency on json-c in slurmctld when running with power saving.
>     Only the new "SLURM_RESUME_FILE" support relies on this, and it will be
>     disabled if json-c support is unavailable instead.
