Author: vangyzen Date: Thu Feb 16 20:47:41 2017 New Revision: 313821 URL: https://svnweb.freebsd.org/changeset/base/313821 Log: Use inet_ntoa_r() instead of inet_ntoa() throughout the kernel inet_ntoa() cannot be used safely in a multithreaded environment because it uses a static local buffer. Instead, use inet_ntoa_r() with a buffer on the caller's stack.
