[PATCH 0/3] module: Make .static_call_sites read-only after init

From: Petr Pavlu
Date: Mon Dec 23 2024 - 04:39:21 EST


Section .static_call_sites holds data structures that need to be sorted and
processed only at module load time. The section is never modified afterwards.
Make it therefore read-only after module initialization to avoid any
(non-)accidental modifications.

Petr Pavlu (3):
module: Constify parameters of module_enforce_rwx_sections()
module: Add a separate function to mark sections as read-only after
init
module: Make .static_call_sites read-only after init
