  <description>This update for qclib fixes the following issues:

qclib was upgraded to version 1.4.1 (bsc#1135781, Fate#327836):

Changes:

  * Added SMT support by properly differentiating between cores and CPUs.
      I.e. switched from qc_num_cpu_* to qc_num_core_* attributes in layers
      CEC, LPAR, ZVM_HYPERVISOR and KVM_HYPERVISOR.
      NOTE: qc_num_cpu_* attributes remain to be valid in these cases to
            preserve backwards compatibility for now. This will be removed in
            one of the next releases! It is recommended to switch to the new
            attributes _now_ and test with CONFIG_V1_COMPATIBILITY disabled!
  * Added new attributes qc_num_threads_cp and qc_num_threads_ifl to layers
      CEC, LPAR and ZVM_HYPERVISOR.
  * Deprecated attribute qc_mobility_eligible (remains valid for now) and
      replaced with qc_mobility_enabled to match z/VM terminology. Likewise
      switched QC_LAYER_TYPE_ZVM_CPU_POOL to QC_LAYER_TYPE_ZVM_RESOURCE_POOL.
  * Moved build customization defines (e.g. CONFIG_V1_COMPATIBILITY) to
      query_capacity.h.
  * Don't build with textual hypfs per default anymore due to unrecoverable
      issues (see section 'Bug fixes'). Since all Linux distributions ship
      with debugfs (providing binary hypfs support), overriding textual hypfs,
      for years, this change will hardly ever be noticable. Enable define
      CONFIG_TEXTUAL_HYPFS in query_capacity.h to revert.
      Note that textual hypfs support will be removed in a future release.

Bug fixes:

  * qc_dump: Don't abort the dump in case qc_test fails.
  * Attributes qc_cp_weight_capping and qc_ifl_weight_capping were set even
      when initial capping was not set in the LPAR's activation profile.
  * Added an exception to consistency check to ignore inconsistencies between
    textual hypfs and STHYI for attributes qc_num_cp_total and
    qc_num_ifl_total in the LPAR layer.
    Background: Textual hypfs cannot tell whether a core is configured or
                not. It therefore reports all cores as configured, which can
                be wrong.
  * Security: Fix PATH attack vulnerability when dumping (see QC_DEBUG=2)
  * STHYI: Add fallback for pre-glibc 2.16 (not using getauxval())
  * Handle mismatching STHYI and /proc/sysinfo layer counts
  * On LPAR, fix incomplete dump of binary hypfs when textual hypfs is mounted
