From e6a2e1b6c24a3993ffbb69a05dda202d2830ad90 Mon Sep 17 00:00:00 2001 From: Daniel Borkmann Date: Sun, 1 Mar 2015 10:14:39 +0000 Subject: [PATCH] arm64: mm: unexport set_memory_ro and set_memory_rw This effectively unexports set_memory_ro and set_memory_rw functions from commit 11d91a770f1f ("arm64: Add CONFIG_DEBUG_SET_MODULE_RONX support"). No module user of those is in mainline kernel and we explicitly do not want modules to use these functions, as they i.e. RO-protect eBPF (interpreted and JIT'ed) images from malicious modifications/bugs. Outside of eBPF scope, I believe also other set_memory_* functions should be unexported on arm64 due to non-existant mainline module user. Laura mentioned that they have some uses for modules doing set_memory_*, but none that are in mainline and it's unclear if they would ever get there.
