Support AuthInfo in slurmdbd.conf that is different from the value in
    slurm.conf.
There is a possible bug in the slurm_get_auth_info function (src/common/slurm_protocol_api.c) that can cause the slurmdbd daemon to look for the AuthInfo parameter in slurm.conf instead of slurmdbd.conf when the auth/munge authentication method is used (AuthType=auth/munge).

Here is the slurmdbd log revealing the problem (debug5() printing were added in the sources) :

slurmdbd: slurmdbd version 15.08.7 started

...

Then 60 seconds later, the auth_info value returned by slurm_get_auth_info is NULL:

slurmdbd: debug5: Leaving ../../../src/common/slurm_protocol_api.c, slurm_get_auth_info, auth_info=(null)

and slurmdbd continues without crashing, but I am not sure it is in a safe state.

When applying this patch :

        return auth_info;
 }

the auth_info value is now valid and consistent with the slurmdbd.conf setting:

contribs/cray/csm/slurmconfgen_smw.py - avoid erroneously including
repurposed compute nodes in the list of nodes to start slurmd.

When the slurmctld is in background mode, it will issue double
  free calls on the incomming message buffers, likely leading
  an abort.

Do not automatically relocate an advanced reservation for individual cores
    that spans multiple nodes when nodes in that reservation go down (e.g.
    a 1 core reservation on node "tux1" will be moved if node "tux1" goes
    down, but a reservation containing 2 cores on node "tux1" and 3 cores on
    "tux2" will not be moved node "tux1" goes down). Advanced reservations for
    whole nodes will be moved by default for down nodes.

and the job kept pending.

Commit fa331e30 fixes this.  The logic was bad to begin with...

uint32_t new_cpus = detail_ptr->num_tasks
	/ detail_ptr->cpus_per_task;

The / should had been * this whole time.  This was the reason we found
this in the first place.

If scancel is operating on large number of jobs and RPC responses from
    slurmctld daemon are slow then introduce a delay in sending the cancel job
    requests from scancel in order to reduce load on slurmctld.

Backfill scheduling properly synchronized with Cray Node Health Check.

bug 2350

Properly account for memory, CPUs and GRES when slurmctld is reconfigured
    while there is a suspended job. Previous logic would add the CPUs, but not
    memory or GPUs. This would result in underflow/overflow errors in select
    cons_res plugin.
