Description Hangbin Liu 2019-05-06 09:55:02 UTC 
Description of problem:

On RHEL8 and latest linux kernel, AF_MAX is defined 45 in include/linux/socket.h:

#define AF_XDP          44
#define AF_MAX          45       /* For now.. */

But current glibc-headers on RHEL8 still defined

#define PF_MAX          44

This makes kernel self test socket.c failed as it checks socket(AF_MAX,0,0) return value.
Comment 1 Florian Weimer 2019-05-06 11:55:49 UTC 
This test is generally invalid because you cannot assume that the userspace headers match what the host kernel uses.

However, we can view this as a request to backport this upstream commit:

commit 38b0593e9a862c3b35392a0f5b202696b8116aa3
Author: Tobias Klauser <tklauser>
Date:   Tue Aug 21 17:22:53 2018 +0000

    Add PF_XDP, AF_XDP and SOL_XDP from Linux 4.18 to bits/socket.h.
    
    This patch adds the PF_XDP, AF_XDP and SOL_XDP macros from Linux 4.18 to
    sysdeps/unix/sysv/linux/bits/socket.h.

Verified with linux/tools/testing/selftests/net/socket.c test case
