This is a new message when "PrologFlags=contain" or
  "PrologFlags=alloc" is configured.

Minor fix to commit 1e6b7522 in
  the case where user specification of specialized cores is disabled.
bug 3349

If a job specifies --core-spec and the node has identified specialized
  cores using the CpuSpecList option which are not the default cores
  (e.g. the first cores rather than the last cores on each socket),
  the the user's cores will be selected from those identified in the
  configuration.

Was printing int64 using %ld, which generated a warning on some systems

Do not allocate specialized cores to jobs using the --exclusive option.

Fix memory and file descriptor leaks in slurmd daemon's sbcast logic.

The part_ptr is sent into the function, there is no reason to look it up
again.  Coverity reported this.

TravisCI uses 2-cpu nodes, so this causes the test to fail
as a suitable node cannot be found.

Plugins are deprecated and will be removed in 17.02.

Modify regression test1.89 to avoid leaving vestigial job. Also reduce

Reverts most of commit 84023f27.

Searching the PATH in slurmd can fail due to root_squash'd NFS
filesystems, leading to the "wrong" program being launched.

If you'd like the performance benefit from avoiding this lookup
during each separate task launch, set SLURM_TEST_EXEC=1 instead
which will perform the lookup once within srun, which then ensures
the lookup happens under the users own environment and not that
of the slurmd.

Bug 2992.

If running burst_buffer/cray plugin on emulated Cray (NOT a real
   Cray system with Cray APIs) and the burst buffer state information
   includes information about buffers associated with jobs which
   are either completed or no longer exist (i.e. the burst buffer
   state information is old), then ignore that old state information.
   This might possibly be related to bug 3295 if their configuration
   is bad.

level.

Revise commit e6ef1f0c
The root cause of the failure is a bug in HWLOC that has since
been fixed in HWLOC version 1.11.5.

If the second call to getgrouplist() found additional groups,
ngroups will be overwritten with this new larger value, while
the gids list would be truncated. (ngroups is a value-result arg.)
This will then lead to _gids_cache_lookup() returning the wrong
number of groups including invalid parts of memory, which are likely
to include some zeros.

Those zeros could then make it to the setgroups() call and thus
give the user access to the root group. Especially as setgroups
will succeed as long as the array does not contain -1 as a gid.

Bug 3320.

task/cgroup - Change error message if CPU binding can not take place to
    better identify the root cause of the problem. Specifically, if
    the hwloc_get_obj_below_by_type() function call completely fails
    that is likely due to task/affinity not being configured, so
    cpusets are not configured. Previous message was
    "task/cgroup: task[%u] infinite loop broken while trying to provision compute elements using %s (bitmap:%s)"
    The new message is
    "task/cgroup: hwloc_get_obj_below_by_type() failing, task/affinity plugin also required"

uint32_t needs %u on 32-bit platforms. Noticed by clang/travisci.
