An update that solves one vulnerability and has two fixes
is now available.

Description:

This update for slurm_20_11 fixes the following issues:

Updated to 20.11.7

Summary of new features:

* CVE-2021-31215: Fixed a remote code execution as SlurmUser (bsc#1186024).
* slurmd - handle configless failures gracefully instead of hanging
indefinitely.
* select/cons_tres - fix Dragonfly topology not selecting nodes in the
same leaf switch when it should as well as requests with *-switches
option.
* Fix issue where certain step requests wouldn't run if the first node
in
the job allocation was full and there were idle resources on other nodes
in the job allocation.
* Fix deadlock issue with <Prolog|Epilog>Slurmctld.
* torque/qstat - fix printf error message in output.
* When adding associations or wckeys avoid checking multiple times a user
or cluster name.
* Fix wrong jobacctgather information on a step on multiple nodes due to
timeouts sending its the information gathered on its node.
* Fix missing xstrdup which could result in slurmctld segfault on array
jobs.
* Fix security issue in PrologSlurmctld and EpilogSlurmctld by always
prepending SPANK_ to all user-set environment variables. CVE-2021-31215.
* Fix sacct assert with the --qos option.
* Use pkg-config --atleast-version instead of --modversion for systemd.
* common/fd - fix getsockopt() call in fd_get_socket_error().
* Properly handle the return from fd_get_socket_error() in
_conn_readable().
* cons_res - Fix issue where running jobs were not taken into
consideration when creating a reservation.
* Avoid a deadlock between job_list for_each and assoc QOS_LOCK.
* Fix TRESRunMins usage for partition qos on restart/reconfig.
* Fix printing of number of tasks on a completed job that didn't request
tasks.
* Fix updating GrpTRESRunMins when decrementing job time is bigger than it.
* Make it so we handle multithreaded allocations correctly when doing
--exclusive or --core-spec allocations.
* Fix incorrect round-up division in _pick_step_cores
* Use appropriate math to adjust cpu counts when --ntasks-per-core=1.
* cons_tres - Fix consideration of power downed nodes.
* cons_tres - Fix DefCpuPerGPU, increase cpus-per-task to match with
gpus-per-task * cpus-per-gpu.
* Fix under-cpu memory auto-adjustment when MaxMemPerCPU is set.
* Make it possible to override CR_CORE_DEFAULT_DIST_BLOCK.
* Perl API - fix retrieving/storing of slurm_step_id_t in job_step_info_t.
* Recover state of burst buffers when slurmctld is restarted to avoid
skipping burst buffer stages.
* Fix race condition in burst buffer plugin which caused a burst buffer in
stage-in to not get state saved if slurmctld stopped.
* auth/jwt - print an error if jwt_file= has not been set in slurmdbd.
* Fix RESV_DEL_HOLD not being a valid state when using squeue --states.
* Add missing squeue selectable states in valid states error message.
* Fix scheduling last array task multiple times on error, causing segfault.
* Fix issue where a step could be allocated more memory than the job when
dealing with --mem-per-cpu and --threads-per-core.
* Fix removing qos from assoc with -= can lead to assoc with no qos
* auth/jwt - fix segfault on invalid credential in slurmdbd due to missing
validate_slurm_user() function in context.
* Fix single Port= not being applied to range of nodes in slurm.conf
* Fix Jobs not requesting a tres are not starting because of that tres
limit.
* acct_gather_energy/rapl - fix AveWatts calculation.
* job_container/tmpfs - Fix issues with cleanup and slurmd restarting on
running jobs.
