That thing comes from:
SYM_FUNC_START(vmx_do_interrupt_irqoff)
VMX_DO_EVENT_IRQOFF CALL_NOSPEC _ASM_ARG1
SYM_FUNC_END(vmx_do_interrupt_irqoff)
at the end of arch/x86/kvm/vmx/vmenter.S.
I know Sean had a patchset to cleanup that gunk. Sean?
From reading objtool docs, those functions (vmx_do_nmi_irqoff() too AFAICT)
should have FRAME_BEGIN/FRAME_END but if I do that, objtool bitches
differently:
arch/x86/kvm/kvm-intel.o: warning: objtool: vmx_do_interrupt_irqoff+0xc: undefined stack state
Suggestions?
The other file it warns about is:
vmlinux.o: warning: objtool: .altinstr_replacement+0x2eb: call without frame pointer save/setup

That series was just for the actual VM-Enter/VM-Exit path. vmx_do_interrupt_irqoff()
is unrelated, it's just another asm chunk of code that happnes to live in vmenter.S
(which is obviously is a bit of a misnomer these days).

That function does create a stack frame, just without using FRAME_BEGIN/END so
it's not dependent on using frame pointers. Ironically, the intent is to try and
placate objtool.
IIUC, this warning just stared showing up with the alternatives changes? Does
CALL_NOSPEC generate different code now?
.macro VMX_DO_EVENT_IRQOFF call_insn call_target
/*

and $-16, %rsp

Sneaky.
> IIUC, this warning just stared showing up with the alternatives changes?
Yeah, perhaps the other one triggered this one too but it wasn't in the 0day
report. The two warnings I reproduced here are:
arch/x86/kvm/kvm.o: warning: objtool: .altinstr_replacement+0xc5: call without frame pointer save/setup
vmlinux.o: warning: objtool: .altinstr_replacement+0x2eb: call without frame pointer save/setup
and the other one is caused by the alternatives missing ASM_CALL_CONSTRAINT %rsp
handing into the inline asm.
> Does CALL_NOSPEC generate different code now?
Hm, so I've been staring at this for a long time today and maybe I've veered off
into the weeds already ... :-\
So we use the asm variant of that CALL_NOSPEC thing:
.globl vmx_do_interrupt_irqoff ; .balign 16, 0x90;; ; vmx_do_interrupt_irqoff: endbr64
VMX_DO_EVENT_IRQOFF CALL_NOSPEC rdi
.type vmx_do_interrupt_irqoff STT_FUNC ; .set .L__sym_size_vmx_do_interrupt_irqoff, .-vmx_do_interrupt_irqoff ; .size vmx_do_interrupt_irqoff, .L__sym_size_vmx_do_interrupt_irqoff
with
.macro CALL_NOSPEC reg:req
__CS_PREFIX \reg
call __x86_indirect_thunk_\reg
.endm
so the end-result is, what, this perhaps?
ffffffff81070e20 <vmx_do_interrupt_irqoff>:
ffffffff81070e20: f3 0f 1e fa endbr64
ffffffff81070e24: 55 push %rbp
ffffffff81070e25: 48 89 e5 mov %rsp,%rbp
<--- new stack frame
ffffffff81070e28: 48 83 e4 f0 and $0xfffffffffffffff0,%rsp
ffffffff81070e2c: 6a 18 push $0x18
ffffffff81070e2e: 55 push %rbp
ffffffff81070e2f: 9c pushf
ffffffff81070e30: 6a 10 push $0x10
push things on the stack...
ffffffff81070e32: e8 09 67 60 00 call ffffffff81677540 <__x86_indirect_thunk_rdi>
ffffffff81070e37: 48 89 ec mov %rbp,%rsp
ffffffff81070e3a: 5d pop %rbp
restore stack.
ffffffff81070e3b: e9 30 68 60 00 jmp ffffffff81677670 <__x86_return_thunk>
So that function has a proper stack frame.
Why doesn't objtool recognize that?
I betcha it is something with that has_valid_stack_frame() from
if (opts.stackval && func && !is_special_call(insn) &&
!has_valid_stack_frame(&state)) {
WARN_INSN(insn, "call without frame pointer save/setup");
return 1;
}
the objtool check. And I see "cfi" there and my brain says "nope". :)
Hmmm.

Right, about that. I still see:
vmlinux.o: warning: objtool: svm_vcpu_enter_exit+0xb0: call to sev_es_host_save_area() leaves .noinstr.text section

Gah, sev_es_host_save_area() needs to be tagged __always_inline.

Which is in fact test_cc() from em_loop().
Now, that .config is a FRAME_POINTER build, and the fast-call thing
don't do frames, so it is right to complain. Big question is why it
didn't complain previously I suppose.
Also, notably, this patch:
https://lkml.kernel.org/r/20231204093732.323101886@infradead.org
cures things.
Let me poke a little more...

ha! the below (whitespace damanged because copy/paste sucks), also works.
For some reason GCC thought it was fun to put that CALL outside the callframe, silly thing.

Speaking of that series, do you need/want any help pushing it along? I ran into
build issues[*] and didn't have the cycles to fully figure things out at the time.
This fails for some of my builds that end up with CONFIG_OBJTOOl=n. Adding a
stub for ASM_ANNOTATE() gets me past that:

Right, saw that. Life caught up with me for a bit and now I'm struggling
with this giant backlog of things.
That is to say, if you have cycles for this, then please. Otherwise,
I'll get to it eventually.
