[PATCH v3 0/5] pmstat interface fixes

Posted by Ross Lagerwall 5 months ago

Clarify and fix usage of the pmstat hypervisor and tools interfaces
regarding sizes of buffers passed in.

Ross Lagerwall (5):
  x86/pmstat: Check size of PMSTAT_get_pxstat buffers
  public/sysctl: Clarify usage of pm_{px,cx}_stat
  cpufreq: Avoid potential buffer overrun and leak
  libxc/PM: Ensure pxstat buffers are correctly sized
  libxc/PM: Retry get_pxstat if data is incomplete
