make it to the slurmctld when using message aggregation.

    for better robustness.  This cray/select plugin code has
    been modified to remove a possible timing window where two
    aeld pthreads could exist, interfering with each other through
    the global aeld_running variable.

    An additional validity check has been added to the data provided
    to aeld through an alpsc_ev_set_application_info() call.
    If an error is returned from that call, only certain errors
    need the current socket connection closed to aeld and a new
    connection established.  Other error returns will log an
    error message and keep the current session established with
    aeld.

slurm.conf instead of all.  If looking for specific addresses use
TopologyParam options No*InAddrAny.

This was broken in 15.08 with the advent of the referenced TopologyParams

at the same time.

Bug 2683

Turns out making a variable static in a function will make it not safe
when dealing with threads.

With slurm-15.08.10, we're seeing occasional segfaults in slurmstepd. The logs point to the following line: slurm-15.08.10/src/slurmd/slurmstepd/mgr.c:2612

On that line, _get_primary_group() is accessing the results of getpwnam_r():
    *gid = pwd0->pw_gid;

If getpwnam_r() cannot find a matching password record, it will set the result (pwd0) to NULL, but still return 0. When the pointer is accessed, it will cause a segfault.

Checking the result variable (pwd0) to determine success should fix the issue.

Do not attempt to power down a node which has never responded if the
    slurmctld daemon restarts without state.

Bug 2656

burst_buffer/cray - Don't call Datawarp "paths" function if script includes
    only create or destroy of persistent burst buffer. Some versions of Datawarp
    software return an error for such scripts, causing the job to be held.

that wasn't set up correctly.

power/cray - Fix bug introduced in 15.08.10 preventin operation in many
    cases.

burst_buffer/cray - Fix for script creating or deleting persistent buffer
    would fail "paths" operation and hold the job.

burst_buffer/cray - Decrement job's prolog_running counter if pre_run fails.
bug 2621

If a job is no longer in configuring state, then clear the prolog_running
  counter on slurmctld restart or reconfigure.
bug 2621

When determining when a pending job will be able to start, rather
  than testing after removing each running job and trying to schedule
  the pending jobs, remove multiple jobs that all end about the
  same time before testing. This reduces the number of calls to
  the job placement logic, which is time consuming.

Fix for job "--contiguous" option that could cause job allocation/launch
    failure or slurmctld crash.
