From 745cb7f8a5de0805cade3de3991b7a95317c7c73 Mon Sep 17 00:00:00 2001 From: "Dmitry V. Levin" Date: Tue, 7 Mar 2017 23:50:50 +0300 Subject: [PATCH] uapi: fix linux/packet_diag.h userspace compilation error Replace MAX_ADDR_LEN with its numeric value to fix the following linux/packet_diag.h userspace compilation error: /usr/include/linux/packet_diag.h:67:17: error: 'MAX_ADDR_LEN' undeclared here (not in a function) __u8 pdmc_addr[MAX_ADDR_LEN]; This is not the first case in the UAPI where the numeric value of MAX_ADDR_LEN is used instead of symbolic one, uapi/linux/if_link.h already does the same: $ grep MAX_ADDR_LEN include/uapi/linux/if_link.h __u8 mac[32]; /* MAX_ADDR_LEN */ There are no UAPI headers besides these two that use MAX_ADDR_LEN.
