channel with the slurmstepd on that node.

Fix slurmstepd race condition when separate threads are reading and
modifying the job's environment, which can result in the slurmstepd failing
with an invalid memory reference. Observed at shutdown when trying
to run the task epilog and trying to read the env var:
SLURM_STEP_KILLED_MSG_NODE_ID

Without this flag, if the configuration changes or is inconsistent
between nodes then the pack and unpack can be out of sync in terms
of what data is expected. This will let server tell the client what
data is packed.

Without this patch, free() is called on a random memory location
(i.e. whatever is on the stack), which can result in slurmstepd
dying and a completed job not being purged in a timely fashion.

Fix race condition in authentication credential creation that could corrupt
memory. (NOTE: This race condition has existed since 2003 and would be
exceedingly rare.)

This permits a single gres.conf file to be used for a
heterogeneous cluster.

This is needed for job arrays with discontiguous task ID values
(e.g. "123_[1,3,5,...99999]")

Previously job arrays were only listed with their native job ID
(e.g. 123_0 listed as 123, 123_1 as 124, etc). Now lists the job ID
using both format (e.g. "123_1 (124)"). The same format is used
for job step IDs (e.g. "123_1.2 (124.2)").

the slurmctld throws a fatal error.

This adds a mechanism to kill a hung apbasil command

instead of when running on the node for the first time.

Add SLURM_CLUSTER_NAME to environment variables passed to PrologSlurmctld,
Prolog, EpilogSlurmctld, and Epilog.

Previous logic never reopened the file, preventing proper functioning
of logrotate.

Use hash function to locate job records for improved performance.

Change partition write lock to a read lock as we use a different
mechanism for hidden partitions in getting individual jobs.

Correct logic returning remaining job dependencies in job information
reported by scontrol and squeue. Eliminates vestigial descriptors with
no job ID values (e.g. "afterany"). As depdencies are removed, the
job ID values were removed from the strings, but not the descriptors.
This eliminates both. It also checks the full job ID to make sure we do
not remove "afterany:1234" when job "123" completes.

Fix race condition on batch job termination that could result in a job exit
code of 0xfffffffe if the slurmd on node zero registers its active jobs at
the same time that slurmstepd is recording the job's exit code.

proctrack/cgroup - Add locking to prevent race condition where one job step
is ending for a user or job at the same time another job stepsis starting
and the user or job container is deleted from under the starting job step.

Substantial performance improvement for systems with Shared=YES or FORCE
and large numbers of running jobs (replace bubble sort with quick sort).

Add ability to clear a node's DRAIN flag using scontrol or sview by setting
it's state to "UNDRAIN". The node's base state (e.g. "DOWN" or "IDLE") will
not be changed.
