Analyze and fix the following issue in the Linux kernel code: tracing/function-graph: Use correct string size for snprintf
Problem Details: The nsecs_str string is a local variable defined as: char nsecs_str[5]; It is possible for the snprintf call to use a size value larger than the size of the string. This should not cause a buffer overrun as it is written now due to the value for the string format "%03lu" can not be larger than 1000. ...
