From d3af2058e2753516b9aaf7f6d71162363eea11d4 Mon Sep 17 00:00:00 2001 From: Ross Burton Date: Mon, 8 Feb 2016 20:35:40 +0000 Subject: lib/oe/qa: ELFFile: check that a path is a file before opening it When opening an ELF file check that a filename points to a normal file before attempting to open it, as if the file turns out to be something more exotic like a FIFO it could hang forever.
