+Subject: [PATCH] Replace deprecated inet_ntoa with safer inet_ntop
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+inet_ntoa() is a legacy API with MT issues. Use the recommended
+alternative instead. This makes some code checkers happy, and could
+potentially fix issues if other parts of the process were to use
+inet_ntoa() at the same time..

-While emulating IRC DCC commands, tcp_emu() uses 'mbuf' size
-'m->m_size' to write DCC commands via snprintf(3). This may
