In the past 2 years, there has been no security problem that was X32-specific

Hence, I would like to ask you to reconsider the ability to run X32 binaries.

Hello Arjan.
Thanks for your answers.

well the flipside argument is one of security attack surface; adding a
whole
new surface for something we don't ship/use ourselves will give the
security
folks some shivers..... it's a bit of a balance as a result. On 12/25/2016 1:19 AM, SH wrote:
That's true if you want to allow compiling in x32 mode.
It's easier for running x32 binaries (maybe produced on another system):
this requires only that the kernel
contains the given feature (CONFIG_X86_X32).
For example, I regularly build my x32 binaries on Ubuntu (which has
a x32 tool chain and libraries) and can run the (statically
linked) x32 binary on openSUSE boxes (which have no x32 tool chain and
no x32 libraries).
Does Clear Linux support running binaries for the
x32 ABI?
currently we do not support this; we can certainly look into it,
the most complicated factor will be build infrastructure rather
than packaging.
