+
+From 46e3aeb07702f57d389fbfcade9d4ef66218dc53 Mon Sep 17 00:00:00 2001
+From: Frank Henigman <fjhenig...@google.com>
+Date: Fri, 14 Dec 2012 20:52:17 +0000
+Subject: mesa: add bounds checking for uniform array access
+
+No piglit regressions and now passes glsl-uniform-out-of-bounds-2.
+
+validate_uniform_parameters now checks that the array index is
+valid. This means if an index is out of bounds, glGetUniform* now
+fails with GL_INVALID_OPERATION, as it should.
+_mesa_uniform and _mesa_uniform_matrix also call
+validate_uniform_parameters so the bounds checks there became
+redundant and were removed.
+
+The test in glGetUniformLocation is modified to check array bounds
+so it now returns GL_INVALID_INDEX (-1) if you ask for the location
+of a non-existent array element, as it should.
+
