Compiling with clang and -Wundef makes the compiler report a usage of undefined PF_MAX macro in security/selinux/include/classmap.h: In file included from scripts/selinux/mdp/mdp.c:48: security/selinux/include/classmap.h:37:31: warning: no previous extern declaration for non-static variable 'secclass_map' [-Wmissing-variable-declarations] struct security_class_mapping secclass_map[] = { ^ security/selinux/include/classmap.h:235:5: error: 'PF_MAX' is not defined, evaluates to 0 [-Werror,-Wundef] #if PF_MAX > 43 ^ In file included from scripts/selinux/genheaders/genheaders.c:17: security/selinux/include/classmap.h:37:31: warning: no previous extern declaration for non-static variable 'secclass_map' [-Wmissing-variable-declarations] struct security_class_mapping secclass_map[] = { ^ security/selinux/include/classmap.h:235:5: error: 'PF_MAX' is not defined, evaluates to 0 [-Werror,-Wundef] #if PF_MAX > 43 ^ PF_MAX is defined in include/linux/socket.h but not in include/uapi/linux/socket.h. Therefore host programs have to rely on the definition from libc's /usr/include/bits/socket.h, included by <sys/socket.h>. Fix the issue by using sys/socket.h in mdp and genheaders. When classmap.h is included by security/selinux/avc.c, it uses the kernel definition of PF_MAX, which makes the test consistent.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
