      Fix race condition with getgrouplist(). · 8cb636dd
      Tim Wickberg authored
      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.

      Change task/cgroup error message · e6ef1f0c
      Morris Jette authored
      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"

      cray/burst_buffer - Increase timer · b4763c75
      Morris Jette authored
      cray/burst_buffer - Increase time to synchronize operations between threads
          from 5 to 60 seconds ("setup" operation time observed over 17 seconds).
          This should fix a race condition between a thread performing a buffer
          creation (setup) and a thread looking for unexpected buffers. If a
          buffer is found during the time window allowed for creation, it's
          space will be counted twice. First by the status checking thread
          and second by the thread doing the creation. The deallocation only
          happens once, so the used space information can be left with an
          invalid value.

      Fix SuspendExcNodes and SuspendExcParts on slurmctld SIGHUP. · bb06dd65
      Alejandro Sanchez authored
      On a reconfig, the exc_node_bitmap is cleared but then it was
      not built again since last_work_scan was declared as a local static
      variable in _do_power_work(). The fix is to make it global within the
      plugin and reinitialize it to 0 on _init_power_config().

      Correct malloc data type · a12e1a1c
      Morris Jette authored
      sched/backfill plugin: Make malloc match data type (defined as uint32_t and
          allocated as int). No failures observed, if type "int" is smaller than
          "uint32_t", it could result in an invalid memory reference.

      Fix slurm_job_cpus_allocated_str_on_node_id() API call. · 0ed6488e
      Sergey Meirovich authored
      Fix API call: slurm_job_cpus_allocated_str_on_node_id() and
      in turn slurm_job_cpus_allocated_str_on_node() to return correct
      results for anything but first node. This was caused by missed logic
      to calculate fist bit belongs to particular node. Lookup was always
      starting from bit 0.

      Modify backfill algorithm · 6008b021
      Morris Jette authored
      Modify backfill algorithm to improve performance with large numbers of
          running jobs. Group running jobs that end in a "similar" time frame using a
          time window that grows exponentially rather than linearly. The original
          window sizes were (in units of minutes):
          0, 1, 2, 3, 4, 5, 6, 7, ... minutes
          The new window sizes are:
          0.5, 1, 2, 4, 8, 16, 32, ... minutes
          This can dramatically reduce the number of instances where the very time
          consuming "can the pending job run now" operation is executed, especailly
          if there are 1000+ running jobs.
