[PATCH 0/5] Coverity fixes for malloc

[Anatoly Burakov <anatoly.burakov@intel.com>]

This patchset fixes a few Coverity issues in malloc
introduced by recent DPDK memory hotplug patchset.

Coverity issues fixed:
- 272571 - negative return not handled
- 272597 - negative return not handled
- 272574 - use value before verification
- 272590 - negative return not handled
- 272566 - possible null dereference

The following coverity issues were not fixed:
- 272573 - calling memset with size 0
  - This is intentional, size will not be 0 in malloc debug

Also, replace all instaces of snprintf with strlcpy.

Anatoly Burakov (5):
  malloc: replace snprintf with strlcpy
  malloc: fix potential out-of-bounds array access
  malloc: fix potential negative return
  malloc: fix potential dereferencing of NULL pointer
  malloc: fix potential negative return
