From 4a306ef1c8ff1cac292c2fd56a3b91d7bfdecefc Mon Sep 17 00:00:00 2001 From: "H.J. Lu" Date: Mon, 13 Nov 2017 08:02:39 -0800 Subject: ld.so: Add architecture specific fields To support Intel Control-flow Enforcement Technology (CET) run-time control: 1. An architecture specific field in the writable ld.so namespace is needed to indicate if CET features are enabled at run-time. 2. An architecture specific field in struct link_map is needed if CET features are enabled in an ELF module. This patch adds dl-procruntime.c to the writable ld.so namespace and link_map.h to struct link_map. Tested with build-many-glibcs.py. * elf/dl-support.c: Include . * include/link.h: Include . * sysdeps/generic/dl-procruntime.c: New file. * sysdeps/generic/link_map.h: Likewise. * sysdeps/generic/ldsodefs.h: Include in the writable ld.so namespace. --- elf/dl-support.c | 1 + 1 file changed, 1 insertion(+) (limited to 'elf/dl-support.c') diff --git a/elf/dl-support.c b/elf/dl-support.c index 5e3de90598..235d3a7f46 100644 --- a/elf/dl-support.c +++ b/elf/dl-support.c @@ -126,6 +126,7 @@ int _dl_starting_up = 1; void *_dl_random; /* Get architecture specific initializer. */ +#include #include /* Initial value of the CPU clock. */ -- cgit 1.4.1
