From ac10cdedd136689028223088ffca80b98c7bbaff Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Sat, 2 Jul 2016 10:33:34 +0200 Subject: [PATCH] lib/gen_tables.c: define EHWPOISON when not available When building on some old system with old kernel headers, the gen_tables.c program (built natively) doesn't build due to missing EHWPOISON. This commit defines EHWPOISON to the value found in asm-generic kernel headers, which is correct for most (but not all architectures). Anyway, the whole concept of building a program on the host to generate a table with errno values, then built into a target program is inherently broken, so our fix is not more broken than the rest of the mechanism used by audit.
