From 610d015143e88629eab07067a4ae0c1d7548cfaf Mon Sep 17 00:00:00 2001
From: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
Date: Thu, 2 Jun 2016 23:03:27 -0300
Subject: [PATCH] Rename xfree() to libnftnl_xfree() to avoid symbol naming
conflict
When ELF binaries and shared libraries are used, the internal
functions of libnftnl such as xfree() are not visible to the outside
world (their visibility is 'hidden'). Therefore, the fact that other
programs (especially nftables) may have symbols with the same name
does not cause any problem.
However, when doing static linking on a non-ELF platform (such as
Blackfin, which uses the FLAT binary format), there is no way of
encoding this visibility. Therefore, the xfree() symbols of libnftnl
becomes visible to the outside world, causing a conflict with the
xfree() symbol defined by nftables.
To solve this, this patch renames the libnftnl xfree() function to
libnftnl_xfree().
