+Subject: [PATCH] nativesdk-glibc: Fix buffer overrun with a relocated SDK
+
+When ld-linux-*.so.2 is relocated to a path that is longer than the
+original fixed location, the dynamic loader will crash in open_path
+because it implicitly assumes that max_dirnamelen is a fixed size that
+never changes.
+
+The allocated buffer will not be large enough to contain the directory
+path string which is larger than the fixed location provided at build
+time.
+
+Upstream-Status: Inappropriate [OE SDK specific]
