Subject: [PATCH 0/2] ELF tests in Python and libio vtables/RELRO interaction
Date: Mon, 11 Apr 2022 14:56:20 +0200 [thread overview]
Message-ID: <cover.1649676847.git.fweimer@redhat.com> (raw)
The first patch adds a basic ELF file parser (without any external
dependencies). The second patch switches to the custom linker script by
default, fixing bug 25812. It uses a new Python test to verify that the
vtables are indeed covered by PT_GNU_RELRO. I considered moving the
vtables to .data.rel.ro instead, but this would still leave some
function pointer arrays unprotected.
Tested on i686-linux-gnu and x86_64-linux-gnu. Built with
build-many-glibcs.py (after fixing the recent Hurd build regression
locally).
