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
