From 99e2fbcb69f0759432c4cfa0b6e1afa006f22930 Mon Sep 17 00:00:00 2001 From: Andrew Scull Date: Mon, 30 May 2022 10:00:04 +0000 Subject: [PATCH] linker_lists: Rename sections to remove . prefix Rename the sections used to implement linker lists so they begin with '__u_boot_list' rather than '.u_boot_list'. The double underscore at the start is still distinct from the single underscore used by the symbol names. Having a '.' in the section names conflicts with clang's ASAN instrumentation which tries to add redzones between the linker list elements, causing expected accesses to fail. However, clang doesn't try to add redzones to user sections, which are names with all alphanumeric and underscore characters.
