[PATCH v7 00/16] Introduce secure memory zero functions

[Stephen Hemminger <stephen@networkplumber.org>]

This series handles memset related bugs indentified by PVS Studio.
The root cause is that Gcc and other compilers are free to
optimize away memset called before free. This is handled in
other libraries and OS's by the use of special versions of zeroing
and free.

v7 - use bzero_explicit
   - add standalone tests

Stephen Hemminger (16):
  eal: introduce new secure memory zero
  app/test: use unit test runner for string tests
  app/test: add test for rte_memzero_explicit
  eal: add new secure free function
  app/test: use unit test runner for malloc tests
  app/test: add test for rte_free_sensitive
  common/cnxk: remove unused variable
  crypto/qat: force zero of keys
  crypto/qat: fix size calculation for memset
  crypto/qat: use secure free for keys
  bus/uacce: remove memset before free
  compress/octeontx: remove unnecessary memset
  test: remove unneeded memset
  net/ntnic: check result of malloc
  net/ntnic: remove unnecessary memset
  devtools/cocci: add script to find problematic memset
