Description

Trying to compile a recent batman-adv master branch with an 4.11-rc5 kernel on a Debian stable currently fails with the following error:

The problem was probably introduced with this commit:

"uapi: fix linux/if.h userspace compilation errors" (2618be7dcc)

Which is part of Linux since 4.11-rc1.

However, it feels like this issue might actually have the root cause in Debian's UAPI header stuff again (#322). The batman-adv Make process seems to use "linux-headers-4.11.0-rc5+/include/linux/if.h" which just has the KERNEL guard stripped:


#ifndef _LINUX_IF_H
#define _LINUX_IF_H

#include <linux/libc-compat.h>          /* for compatibility with glibc */
#include <linux/types.h>                /* for "__kernel_caddr_t" et al */
#include <linux/socket.h>               /* for "struct sockaddr" et al  */
                /* for "__user" et al           */

#include <sys/socket.h>                 /* for struct sockaddr.         */

[...]

Manually removing this include from the Debian make-kpkg compiled header directory or inserting the "#ifndef __KERNEL__" again helps to compile things again.
