+Subject: [PATCH] libelf: Mark shdr_flags dirty if offset or size changes during update.
+Date: Mon, 13 May 2019 00:13:42 +0200
+Message-Id: <[email protected]>
+
+We forgot to mark the shdr_flags dirty when only the sh_size or
+sh_offset changed during elf_update (). This meant that if there were
+no other shdr changes we only wrote out the section data, but didn't
+write out the shdr table to the file.
