2017-11-17Add Intel CET support for EH in libgcc.Igor Tsimbalist6-13/+106
Control-flow Enforcement Technology (CET), published by Intel, introduces the Shadow Stack feature, which ensures a return from a function is done to exactly the same location from where the function was called. When EH is present the control-flow transfer may skip some stack frames and the shadow stack has to be adjusted not to signal a violation of a control-flow transfer. It's done by counting a number of skiping frames and adjasting shadow stack pointer by this number. Having new semantic of the 'ret' instruction if CET is supported in HW the 'ret' instruction cannot be generated in ix86_expand_epilogue when we are returning after EH is processed. Added a code in ix86_expand_epilogue to adjust Shadow Stack pointer and to generate an indirect jump instead of 'ret'. As sp register is used during this adjustment thus the argument in pro_epilogue_adjust_stack is changed to update cfa_reg based on whether control-flow instrumentation is set. Without updating the cfa_reg field there is an assert later in dwarf2 pass related to mismatch the stack register and cfa_reg value. gcc/ * config/i386/i386.c (ix86_expand_epilogue): Change simple return to indirect jump for EH return if control-flow protection is enabled.

2017-09-26Enable no-exec stacks for more targets using the Linux kernel.Joseph Myers12-0/+76
Building glibc for many different configurations and running the compilation parts of the testsuite runs into failures of the elf/check-execstack test for hppa and microblaze. Those configurations default to executable stacks in the Linux kernel because of VM_DATA_DEFAULT_FLAGS definitions including VM_EXEC (VM_DATA_DEFAULT_FLAGS being the default definition of VM_STACK_DEFAULT_FLAGS). This fails because those configurations are not generating .note.GNU-stack sections to indicate that programs do not need an executable stack. This patch fixes GCC to generate those sections on those architectures (when configured for a target using the Linux kernel), as it does on other architectures, together with adding that section to libgcc .S sources, with the same code as used on other architectures (or a variant using "#ifdef __linux__" instead of the usual "#if defined(__ELF__) && defined(__linux__)" for microblaze, as that configuration doesn't use elfos.h and so doesn't define __ELF__). This suffices to eliminate that glibc test failure. (For hppa, the compilation parts of the glibc testsuite still fail because of the separate elf/check-textrel failure.) gcc: * config/microblaze/linux.h (TARGET_ASM_FILE_END): Likewise. * config/pa/pa.h (NEED_INDICATE_EXEC_STACK): Likewise. * config/pa/pa-linux.h (NEED_INDICATE_EXEC_STACK): Likewise. * config/pa/pa.c (pa_hpux_file_end): Rename to pa_file_end.

2017-06-28Use ucontext_t not struct ucontext in linux-unwind.h files.Joseph Myers12-12/+27
Current glibc no longer gives the ucontext_t type the tag struct ucontext, to conform with POSIX namespace rules. This requires various linux-unwind.h files in libgcc, that were previously using struct ucontext, to be fixed to use ucontext_t instead. This is similar to the removal of the struct siginfo tag from siginfo_t some years ago. This patch changes those files to use ucontext_t instead. As the standard name that should be unconditionally safe, so this is not restricted to architectures supported by glibc, or conditioned on the glibc version. Tested compilation together with current glibc with glibc's build-many-glibcs.py. * config/aarch64/linux-unwind.h (aarch64_fallback_frame_state), config/alpha/linux-unwind.h (alpha_fallback_frame_state), config/bfin/linux-unwind.h (bfin_fallback_frame_state), config/i386/linux-unwind.h (x86_64_fallback_frame_state, x86_fallback_frame_state), config/m68k/linux-unwind.h (struct uw_ucontext), config/nios2/linux-unwind.h (struct nios2_ucontext), config/pa/linux-unwind.h (pa32_fallback_frame_state), config/riscv/linux-unwind.h (riscv_fallback_frame_state), config/sh/linux-unwind.h (sh_fallback_frame_state), config/tilepro/linux-unwind.h (tile_fallback_frame_state), config/xtensa/linux-unwind.h (xtensa_fallback_frame_state): Use ucontext_t instead of struct ucontext.
