* x86: Remove ARCH_CET_LEGACY_BITMAP [BZ #25397]H.J. Lu2020-03-181-1/+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 rowH.J. Lu2020-02-011-1/+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. Lu2019-07-011-0/+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. (modules-names): Add tst-cet-legacy-mod-5a, tst-cet-legacy-mod-5b, tst-cet-legacy-mod-5c, tst-cet-legacy-mod-6a, tst-cet-legacy-mod-6b and tst-cet-legacy-mod-6c. (CFLAGS-tst-cet-legacy-5a.c): New.
