[lttng-dev] [PATCH lttng-tools 00/24] Fix illegal memory accesses

[Mathieu Desnoyers]

Coverity found illegal memory accesses around the use of strncpy().
Implement a lttng_strncpy() which performs sanity check with strlen()
first, and fails if the input string is too long to fit in the
destination length.

Mathieu Desnoyers (24):
  Implement lttng_strncpy safe string copy
