From a93e743e2194085307a9b1a3fccc36004f7ba63c Mon Sep 17 00:00:00 2001 From: Khem Raj Date: Sun, 23 May 2021 07:45:32 -0700 Subject: glibc: Enable memory tagging for aarch64 Glibc on aarch64 has a memory tagging option that can be enabled via GLIBC_TUNABLES="glibc.mem.tagging=$SOMETHING" when glibc is built with memory tagging support and the kernel/HW supports MTE. There should be no side effects unless the user turns it on with approprate HW support Linux 5.4 headers and binutils 2.33.1 or newer is needed.
