If running without AccountingStorageEnforce but with the DBD and
it isn't up when starting the slurmctld you could get into a
corner case where you don't have a QOS list in the assoc_mgr.  Thus no
usage to transfer.

Bug 5156

Try to fill up each socket completely before moving into additional
sockets. This will minimize the number of sockets needed, improving
packing especially alongside MaxCPUsPerNode.

Without this, gang scheduling would incorrectly kick in for
these jobs since active_resmap has not been updated appropriately.

Bug 5146

Caused by a corrupted protocol_version field value being received
by the slurmstepd, as we cannot safely write/read a uint16_t across
the pipe as if it was an int.

Regression caused by commit 90b116c2.

Bug 5133.

Requeued jobs are marked as PENDING|COMPLETING until the epilog checks
in. The issue is that if job_set_alloc_tres gets called while in the
PENDING|COMPLETING state, the job's alloc_tres_str will be free'd. If
this job then gets checkpointed in this state (PENDING|COMPLETING + no
tres_alloc_str) on startup the controller would crash because it
expected the job to have a tres_alloc_str/cnt when in the COMPLETING
state. This could be triggered if starting the controller without the
dbd up. When the dbd comes up, the assoc_cache_mgr calls
_update_job_tres() which calls job_set_alloc_tres. It could also be
triggered by adding new tres.

This most likely started happening in 17.11.5 because of commit
865b672f which introduced calling _update_job_tres() on each job
after the dbd comes up.

Bug 5129.

Use setenv() instead of setenvfs(), since setenvfs() memory allocation
is implemented with xmalloc() and fini_setproctitle() (which is called
on reconfigure) free's the memory with free(), leading to a:
"free(): invalid size" malloc_printerr error.

Bug 5095.

Due to current design the job limits are checked before the allocation is
made when one specifies a generic gres and a specific gres type is configured.
The workaround for now is to define a job submit plugin to control the user
request and succesfully apply limits.

Bug 5108

Turns out the partititon's billing tres was working off the sum of
the node_ptrs which contain the max of all partitions they are in.

This isn't correct since each partition's billing can be different.

Set it correctly here.

These functions are not async-cancel-safe, and cannot safely be cancelled.
This leads to potential deadlock, either between our own locks, or deep
inside glibc when the thread held a malloc arena lock when canceled.

Replace with pthread_signal to the appropriate cond to
wake threads up at the appropriate time instead.

This allows the suspend script to be triggered even if Slurm has the
node(s) in a power_save state.

Bug 5053

When any of these --exclusive modes couldn't be satisfied, Slurm was
returning an incorrect ESLURM_NODE_NOT_AVAIL, having as a consequence
scheduling problems as described in the bug. The fix makes it so the
error code is properly set to ESLURM_NODES_BUSY, fixing also the
scheduling problems and working over the correct share_node_bitmap.

Replace select_p_select_jobinfo_sprint() with the same NO-OP
that the other plugins (except alps and bluegene) have implemented.

Bug 5077.

1. Identifies nodes which are unavailable to a specific job,
adding a call to filter_by_node_owner() in select_nodes()
 where the node list is generated.
2. Removes the "unavail_node_str" argument to select_nodes()
as it is no longer useful. This string originally was originally
generated once at the start of the job scheduling logic for all jobs,
but since each job can have a different set of
 unavailable nodes (dedicated to user, group, etc.)
so the same string for all jobs can be misleading.
