Subject: Another libffi ABI change and another release
Date: Mon, 24 Feb 2020 01:07:00 -0000 [thread overview]
Message-ID: <CACxje59y350iopvc+pdpFU9syjT_UQ4cLKr=Vj5a51-H0q9ttw@mail.gmail.com> (raw)
HJ from Intel just contributed a set of ABI changing patches that will move
us up to .so.8.
These are changes increase trampoline sizes in order to support Intel's
Control-Flow Enforcement Technology (CET), which is designed to counter
return-oriented programming attacks. My understanding is that this might
require changes to kernel trampoline emulators, like EMUTRAMP and S.A.R.A.
(copying the author).
The only other notable changes are some 32-bit PPC fixes and a soft-float
MIPS correction.
I just thought I'd float this idea in case anyone has any pending urgent
changes. I'd like to get a new release out so we can upgrade the libffi in
Fedora (which so far has not published the .7 version).
