Title:
Kernels after 5.16 cannot execute x32-ABI binaries
Status in linux package in Ubuntu:
Confirmed
Bug description:
The kernel configuration option CONFIG_X86_X32_ABI is outcommented for
kernel 5.17 and higher (amd64). x32 binaries are now reporting:
cannot execute binary file: Exec format error
The x32-ABI has its proven merits in some HPC tasks (e.g. link and GC
intensive tasks) because it saves CPU time and critical resources like
energy.
So, the following approach (e.g. Debian) looks more appropriate:
1. Include the x32-relevant code, but disable its use on standard
boots:
CONFIG_X86_X32=y
CONFIG_X86_X32_DISABLED=y
2. Users that must run x32 binaries can easily add the GRUB cmdline
option
syscall.x32=y
to enable x32 binaries.
This could be a good compromise between kernel complexity and resource
efficiency.
