* Changes in Slurm 17.11.4
==========================
-- Add fatal_abort() function to be able to get core dumps if we hit an
"impossible" edge case.
-- Link slurmd against all libraries that slurmstepd links to.
-- Fix limits enforce order when they're set at partition and other levels.
-- Add slurm_load_single_node() function to the Perl API.
-- slurm.spec - change dependency for --with lua to use pkgconfig.
-- Fix small memory leaks in node_features plugins on reconfigure.
-- slurmdbd - only permit requests to update resources from operators or
administrators.
-- Fix handling of partial writes in io_init_msg_write_to_fd() which can
lead to job step launch failure under higher cluster loads.
-- MYSQL - Fix to handle quotes in a given work_dir of a job.
-- sbcast - fix a race condition that leads to "Unspecified error".
-- Log that support for the ChosLoc configuration parameter will end in Slurm
version 18.08.
-- Fix backfill performance issue where bf_min_prio_reserve was not respected.
-- Fix MaxQueryTimeRange checks.
-- Print MaxQueryTimeRange in "sacctmgr show config".
-- Correctly check return codes when creating a step to check if needing to
wait to retry or not.
-- Fix issue where a job could be denied by Reason=MaxMemPerLimit when not
requesting any tasks.
-- In perl tools, fix for regexp that caused extra incorrectly shown results.
-- Add some extra locks in fed_mgr to be extra safe.
-- Minor memory leak fixes in the fed_mgr on slurmctld shutdown.
-- Make sreport job reports also report duplicate jobs correctly.
-- Fix issues restoring certain Partition configuration elements, especially
when ReconfigFlags=KeepPartInfo is enabled.
-- Don't add TRES whose value is NO_VAL64 when building string line.
-- Fix removing array jobs from hash in slurmctld.
-- Print out missing user messages from jobsubmit plugin when srun/salloc are
waiting for an allocation.
-- Handle --clusters=all as case insensitive.
-- Only check requested clusters in federation when using --test-only
submission option.
-- In the federation, make it so you can cancel stranded sibling jobs.
-- Silence an error from PSS memory stat collection process.
-- Requeue jobs allocated to nodes requested to DRAIN or FAIL if nodes are
POWER_SAVE or POWER_UP, preventing jobs to start on NHC-failed nodes.
-- Make MAINT and OVERLAP resvervation flags order agnostic on overlap test.
-- Preserve node features when slurmctld daemons reconfigured including active
and available KNL features.
-- Prevent creation of multiple io_timeout threads within srun, which can
lead to fatal() messages when those unexpected and additional mutexes are
destroyed when srun shuts down.
-- burst_buffer/cray - Prevent use of "#DW create_persistent" and
"#DW destroy_persistent" directives available in Cray CLE6.0UP06. This
will be supported in Slurm version 18.08. Use "#BB" directives until then.
-- Fix task/cgroup affinity to behave correctly.
-- FreeBSD - fix build on systems built with WITHOUT_KERBEROS.
-- Fix to restore pn_min_memory calculated result to correctly enforce
MaxMemPerCPU setting on a partition when the job uses --mem.
-- slurmdbd - prevent infinite loop if a QOS is set to preempt itself.
-- Fix issue with log rotation for slurmstepd processes.
