From 3e9acce8c50883b6cd8a3fb653363d9fa21e1608 Mon Sep 17 00:00:00 2001 From: Fangrui Song Date: Tue, 19 Apr 2022 15:52:27 -0700 Subject: elf: Remove __libc_init_secure After 73fc4e28b9464f0e13edc719a5372839970e7ddb, __libc_enable_secure_decided is always 0 and a statically linked executable may overwrite __libc_enable_secure without considering AT_SECURE. The __libc_enable_secure has been correctly initialized in _dl_aux_init, so just remove __libc_enable_secure_decided and __libc_init_secure. This allows us to remove some startup_get*id functions from 22b79ed7f413cd980a7af0cf258da5bf82b6d5e5.
