There is also a collection of patches to fix some issues with ptrace and the protection keys register (PKRU). PKRU is a real oddity because it is exposed in the XSAVE-related ABIs, but it is generally managed without using XSAVE in the kernel. This fix thankfully came with a selftest to ward off future regressions. Summary: - Clarify XSAVE consistency warnings - Fix up ptrace interface to protection keys register (PKRU) - Avoid undefined compiler behavior with TYPE_ALIGN" * tag 'x86_fpu_for_6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/fpu: Use _Alignof to avoid undefined behavior in TYPE_ALIGN selftests/vm/pkeys: Add a regression test for setting PKRU through ptrace x86/fpu: Emulate XRSTOR's behavior if the xfeatures PKRU bit is not set x86/fpu: Allow PKRU to be (once again) written by ptrace. x86/fpu: Add a pkru argument to copy_uabi_to_xstate() x86/fpu: Add a pkru argument to copy_uabi_from_kernel_to_xstate(). x86/fpu: Take task_struct* in copy_sigframe_from_user_to_xstate() x86/fpu/xstate: Fix XSTATE_WARN_ON() to emit relevant diagnostics |
