*	x86: Add --enable-cet=permissive	H.J. Lu	2020-05-18	1	-8/+17
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	When CET is enabled, it is an error to dlopen a non CET enabled shared library in CET enabled application. It may be desirable to make CET permissive, that is disable CET when dlopening a non CET enabled shared library. With the new --enable-cet=permissive configure option, CET is disabled when dlopening a non CET enabled shared library. Add DEFAULT_DL_X86_CET_CONTROL to config.h.in: /* The default value of x86 CET control. / #define DEFAULT_DL_X86_CET_CONTROL cet_elf_property which enables CET features based on ELF property note. --enable-cet=permissive it to / The default value of x86 CET control. */ #define DEFAULT_DL_X86_CET_CONTROL cet_permissive which enables CET features permissively. Update tst-cet-legacy-5a, tst-cet-legacy-5b, tst-cet-legacy-6a and tst-cet-legacy-6b to check --enable-cet and --enable-cet=permissive.
*	x86: Remove ARCH_CET_LEGACY_BITMAP [BZ #25397]	H.J. Lu	2020-03-18	1	-1/+2
\| \| \| \| \| \| \| \| \| \| \|	Since legacy bitmap doesn't cover jitted code generated by legacy JIT engine, it isn't very useful. This patch removes ARCH_CET_LEGACY_BITMAP and treats indirect branch tracking similar to shadow stack by removing legacy bitmap support. Tested on CET Linux/x86-64 and non-CET Linux/x86-64.

*	x86: Don't make 2 calls to dlerror () in a row	H.J. Lu	2020-02-01	1	-1/+1
\| \| \| \| \| \| \| \| \| \|	We shouldn't make 2 calls to dlerror () in a row since the first call will clear the error. We should just use the return value from the first call. Tested on Linux/x86-64. Reviewed-by: Florian Weimer <fweimer@redhat.com>

*	Call _dl_open_check after relocation [BZ #24259]	H.J. Lu	2019-07-01	1	-0/+76
	This is a workaround for [BZ #20839] which doesn't remove the NODELETE object when _dl_open_check throws an exception. Move it after relocation in dl_open_worker to avoid leaving the NODELETE object mapped without relocation. [BZ #24259] * elf/dl-open.c (dl_open_worker): Call _dl_open_check after relocation. * sysdeps/x86/Makefile (tests): Add tst-cet-legacy-5a, tst-cet-legacy-5b, tst-cet-legacy-6a and tst-cet-legacy-6b.
