commit cea55c7e3af9244e97cd40ffdac8e87ab1258d38
Author: Florian Weimer <fweimer@redhat.com>
Date: Sat Feb 8 09:15:05 2020 +0100
ld.so: Do not export free/calloc/malloc/realloc functions [BZ #25486]
Exporting functions and relying on symbol interposition from libc.so
makes the choice of implementation dependent on DT_NEEDED order, which
is not what some compiler drivers expect.
This commit replaces one magic mechanism (symbol interposition) with
another one (preprocessor-/compiler-based redirection). This makes
the hand-over from the minimal malloc to the full malloc more
explicit.
Removing the ABI symbols is backwards-compatible because libc.so is
always in scope, and the dynamic loader will find the malloc-related
symbols there since commit f0b2132b35248c1f4a80f62a2c38cddcc802aa8c
("ld.so: Support moving versioned symbols between sonames
[BZ #24741]").
Tested on i686-linux-gnu with out the stack protector, and on
x86_64-linux-gnu with stack-protector-strong. Also built with
build-many-glbics.py.
