From 4bc6c2d5d8386800fde23a8e78cd4f04a0ade0ad Mon Sep 17 00:00:00 2001 From: Harry Ciao Date: Wed, 2 Mar 2011 13:46:08 +0800 Subject: SELinux: Auto-generate security_is_socket_class The security_is_socket_class() is auto-generated by genheaders based on classmap.h to reduce maintenance effort when a new class is defined in SELinux kernel. The name for any socket class should be suffixed by "socket" and doesn't contain more than one substr of "socket".
