Misc unsafe warnings when built with strict toolchain #1
Description
Hi,
For static analysis, we turn on a bunch of warnings and features to detect programming bugs in C/C++ code in the Ubuntu toolchain. When building tsn-utils, I received a non-trivial number of warnings (reproduced below).
These typically indicate potentially serious programming issues e.g. buffer overflows, but I didn't get the chance to review them yet.
Best,
LM
