This patch is to fix buffer overflow, return value not unified and
variable type not matched issues. And add some judge logic to improve
code quality.
Changes:
1. Handle the fd properly in the failing case.
2. Fix buffer overflow issues and null pointer access issues.
3. Fix the format issue in log_sys.c.
4. Remove the useless branch and adjust the function logic.
5. Add some checks for the string length before using strcpy/strcat/memcpy.
6. Fix strncpy null-terminated issues.
7. Change the return value to unify the return type.
