      Fix issue when changing a users name in accounting, if using wckeys would execute correctly, but bad memcopy would core the DBD.  No information would be lost or corrupted, but you would need to restart the DBD.

      that derived parameter names are all upper case. Values from the configuration
      files are mixed case (e.g. SLURM_VERSION vs. SlurmdPort).

      select/cray: add linking dependency for libjob.so · 0112a79b
      Morris Jette authored
      This adds a link test for libjob.so
       * salloc needs direct support (Makefile.am),
       * however, X_AC_SGI_JOB comes much later in configure.ac.
      
      (An alternative would be, since the libjob interface has practically not
       changed for 2.6 kernels, to integrate its 19 ioctls into slurm.)

      salloc: support for Cray container IDs · 0344cdf3
      Morris Jette authored
      This adds detection and use of SGI process aggregate job container IDs for
      salloc interactive sessions.
      
      The preferred and documented way to support this on a Cray system is by
      enabling the provided pam_job.so via /etc/pam.d/common-session.
      
      There is a header dependency on job.h. This file depends on the optional
      cray-libjob-devel package, which installs into /opt/cray/job/<version>.
      
      This package is however not always installed or may not be up-to-date.
      Hence the patch "cheats" by duplicating the known prototype of job_getjid().

      select/cray: warn user of wrong ProctrackType · 4545a1f0
      Morris Jette authored
      To work properly, select/cray requires proctrack/sgi_job. In fact, due to the
      way the container functions are called by the slurmstepd, it will only work
      properly with this plugin.
      
      I have considered alternatives, such as falling back to using the SID to
      confirm the allocation. But this attempt to support configuration errors
      creates other problems, such as less stringent error checking.

      slurmstepd: use (SGI) container ID to confirm ALPS reservation · 35f5133e
      Morris Jette authored
      This equips the slurmstepd to use the SGI process aggregate container
      ID to confirm the ALPS reservation.
      
      The way it is coded allows ALPS to return a temporary error in confirming the
      reservation once, the job will then be requeued.
      
      On the other hand, it is mandatory that the Cray job service works correctly,
      therefore errors are returned if
       * job container creation fails or
       * the job is not attached to a container (anticipating later failure in
         _fork_all_tasks() when slurm_container_add() will fail for the same reason).
      
      The patch relies on the internals of the proctrack/sgi_job plugin in order to
      avoid duplicating code. This dependency is made explicit by a configuration
      check of a subsequent patch.
      
      With these two pieces in place, the frontends are set to DRAINING if a system
      administrator forgets to enable the /etc/init.d/job service, as shown in the
      following log entries:

      select/cray: use pagg ID to confirm reservations · ac21f730
      Morris Jette authored
      This uses the SGI container process aggregate ID to confirm the job reservation.
      
      It falls back to using the alloc_sid in case of failure. This fallback
      should be considered really only as a last resort, since it is known that
      session IDs are not unique across multiple login nodes and therefore the
      confirmation of ALPS reservations will fail whenever there is a SID collision
      (the likelihood increases with system size).

      select/cray: add data structure support for confirmation cookie · af59681f
      Morris Jette authored
      This extends the Cray-specific select_jobinfo struct with a confirmation cookie
      field, which is to be used by later patches to store the session SID or PAGG
      container ID.
      
      There is a slight incompatibility with regard to pack/unpack, due to the new
      confirm_cookie format. Since not many Cray installations exist yet, I would
      like to suggest to not do an extra bump of the API version.

      ck/cgroup: return value convention of slurm_container_find · 496a256b
      Morris Jette authored
      This is just for consistency with other proctrack plugins, which all return 0
      to indicate "not found", rather than (uint64_t)-1.

      select/cray: set default TopologyPlugin · b56260ef
      Morris Jette authored
      The select/cray plugin discovers the topology as part of its initialisation and
      generates a node ranking. No further topology information is required by the
      plugin, hence this patch sets the default TopologyPlugin to topology/none.
