Subject: [PATCH] libsepol: Add symver with explicit version to build with ld.gold
Date: Mon, 31 Oct 2016 23:52:27 +0800	[thread overview]
Message-ID: <1477929147-18929-1-git-send-email-jason@perfinion.com> (raw)

The blank default symver fails to compile with ld.gold. This updates the
symver from blank to LIBSEPOL_1.0. The dynamic linker will first look
for the symbol with the explicit version specified. If there is none, it
will pick the first listed symbol so there is no breakage.
This also matches how symvers are defined in libsemanage.
