Pull request overview
This PR addresses multiple Coverity findings across the wolfIP stack and its POSIX/test harnesses, focusing on dead code paths, buffer safety, resource cleanup, and some initialization/locking issues.
Changes:
- Fix ICMP payload copy destination and adjust TCP receive window scaling logic based on RX buffer size.
- Harden POSIX socket wrapper behavior by initializing buffers, refining accept state handling, and making initialization more atomic.
- Reduce test resource leaks and silence ignored-return warnings for
setsockopt(); update test randomness source.
