There is a couple of assembly functions, which are invoked only locally
in the file they are defined. In C, we mark them "static". In assembly,
annotate them using SYM_{FUNC,CODE}_START_LOCAL (and switch their
ENDPROC to SYM_{FUNC,CODE}_END too). Whether FUNC or CODE depends on
ENDPROC/END for a particular function (C or non-C).

These are all functions which are invoked from elsewhere, so we annotate
them as global using the new SYM_FUNC_START. And their ENDPROC's by
SYM_FUNC_END.

And make sure ENTRY/ENDPROC is not defined on X86_64, given these were
the last users.

	David S. Miller, Bill Metzenthen, Matt Fleming, Ard Biesheuvel,
	linux-crypto, linux-efi

These are all functions which are invoked from elsewhere, so we annotate
them as global using the new SYM_FUNC_START (and their ENDPROC's by
SYM_FUNC_END.)

Now, we can finally force ENTRY/ENDPROC to be undefined on X86.

There was no cover letter. I am attaching what is in PATCH 1/27 instead:
Introduce new C macros for annotations of functions and data in
assembly. There is a long-standing mess in macros like ENTRY, END,
ENDPROC and similar. They are used in different manners and sometimes
incorrectly.

So introduce macros with clear use to annotate assembly as follows:

a) Support macros for the ones below
   SYM_T_FUNC -- type used by assembler to mark functions
   SYM_T_OBJECT -- type used by assembler to mark data
   SYM_T_NONE -- type used by assembler to mark entries of unknown type

   They are defined as STT_FUNC, STT_OBJECT, and STT_NOTYPE
   respectively. According to the gas manual, this is the most portable
   way. I am not sure about other assemblers, so we can switch this back
   to %function and %object if this turns into a problem. Architectures
   can also override them by something like ", @function" if they need.

   SYM_A_ALIGN, SYM_A_NONE -- align the symbol?
   SYM_V_GLOBAL, SYM_V_WEAK, SYM_V_LOCAL -- visibility of symbols

b) Mostly internal annotations, used by the ones below
   SYM_ENTRY -- use only if you have to (for non-paired symbols)
   SYM_START -- use only if you have to (for paired symbols)
   SYM_END -- use only if you have to (for paired symbols)

c) Annotations for code
   SYM_FUNC_START_LOCAL_ALIAS -- use where there are two local names for
	one function
   SYM_FUNC_START_ALIAS -- use where there are two global names for one
	function
   SYM_FUNC_END_ALIAS -- the end of LOCAL_ALIASed or ALIASed function

   SYM_FUNC_START -- use for global functions
   SYM_FUNC_START_NOALIGN -- use for global functions, w/o alignment
   SYM_FUNC_START_LOCAL -- use for local functions
   SYM_FUNC_START_LOCAL_NOALIGN -- use for local functions, w/o
	alignment
   SYM_FUNC_START_WEAK -- use for weak functions
   SYM_FUNC_START_WEAK_NOALIGN -- use for weak functions, w/o alignment
   SYM_FUNC_END -- the end of SYM_FUNC_START_LOCAL, SYM_FUNC_START,
	SYM_FUNC_START_WEAK, ...

   SYM_FUNC_INNER_LABEL -- only for labels in the middle of functions
   SYM_FUNC_INNER_LABEL_NOALIGN -- only for labels in the middle of
	functions, w/o alignment

   For functions with special (non-C) calling conventions:
   SYM_CODE_START -- use for non-C (special) functions
   SYM_CODE_START_NOALIGN -- use for non-C (special) functions, w/o
	alignment
   SYM_CODE_START_LOCAL -- use for local non-C (special) functions
   SYM_CODE_START_LOCAL_NOALIGN -- use for local non-C (special)
	functions, w/o alignment
   SYM_CODE_END -- the end of SYM_CODE_START_LOCAL or SYM_CODE_START

   SYM_CODE_INNER_LABEL -- only for labels in the middle of code
   SYM_CODE_INNER_LABEL_NOALIGN -- only for labels in the middle of code

d) For data
   SYM_DATA_START -- global data symbol
   SYM_DATA_END -- the end of the SYM_DATA_START symbol
   SYM_DATA_END_LABEL -- the labeled end of SYM_DATA_START symbol
   SYM_DATA_SIMPLE -- start+end wrapper around simple global data
   SYM_DATA_SIMPLE_LOCAL -- start+end wrapper around simple local data

==========

The macros allow to pair starts and ends of functions and mark functions
correctly in the output ELF objects.

All users of the old macros in x86 are converted to use these in further
patches.

I must say, I don't share this sentiment.

In arm64, we use ENTRY/ENDPROC for functions with external linkage,
and the bare symbol name/ENDPROC for functions with local linkage. I
guess we could add ENDOBJECT if we wanted to, but we never really felt
the need.

Is is necessary to mark an entry as having no type? What is the
default type for an unmarked entry?

I am sorry but I think this is terrible. Do we really need 20+ new
macros to wrap every single assembler directive involved in defining
symbols and setting their attributes?

Is this issue you are solving widely perceived as a problem?

Yes and this is exactly the reason for the new macros. Now, it's a
complete mess. One arch does this, another does that. And we are in a
state to have reliable stacktraces, let objtool check functions, let
objtool generate annotations (e.g. for ORC unwinder), etc.

Without knowing what is start, where is its end, what is function, what
is object (data) etc., it can barely check or even generate anything
automatically. Not speaking about impaired macros like your name/ENDPROC
above.

There was a cleanup in x86 done by Josh and others that we have at least
correct ENTRY+END and ENTRY+ENDPROC annotations in most cases now. Even
though it was concluded the names are weird (leftover from the past). So
yes, there was a discussion about the cleanup, naming and such. And I
came up with the names in this e-mail.

The default is indeed T_NONE. The thing is that most macros use
SYM_START and SYM_END which requires the type as argument. So for
convenience, we define also SYM_T_NONE used e.g. to define SYM_CODE_END:
#define SYM_CODE_END(name)                              \
        SYM_END(CODE, name, SYM_T_NONE)

Despite it needs not be there. But users of the macros should not care.

Basically, most code uses SYM_FUNC_START/END and SYM_DATA_START/END (or
SYM_DATA_SIMPLE). The rest is special cases that _have_ to be annotated
as such anyway (by e.g. SYM_CODE_START/END). Objtool cannot check the
code without this reliably and it is exactly the same as using either
END or ENDPROC for a particular function except people use these in a
wrong way as they are undocumented.

So yes, I believe so.

Hi Jiri,

I can see that these serve a useful purpose (as they are necessary for
asm validation encessary for livepatching), and I am not personally
averse to the new annotations.

However, I am concerned that as-is, this is going to create more
problems for !x86 architectures. More on that below.

If the aim of this series is to introduce something that architectures
use consistently, then can we please actually poke other architectures
about it? e.g. send this to linux-arch, with a cover letter explaining
the idea and asking maintainers to take a look.

I think one reason that ENTRY/END/ENDPROC are used inconsistently is
that they're insufficiently documented. So people assume (inconsistent)
semantics, and often cargo-cult usage without thinking. To avoid that,
could we please document how these new macros should (and should not) be
used?

That way, we have a much better chance of consistency, and it's easier
to figure out if the intended semantics are necessary/sufficient.

Otherwise, I'm worried that bits of this will be inconsistently and
incorrectly cargo-culted into other architectures, making matters worse.

Thanks,
Mark.

You are implying that ENTRY/ENDPROC and 'bare symbol name'/ENDPROC
prevent you from doing any of this, but this is simply not true.

OK, but wrapping asm directives in macros will not suddenly make the
assembler care about whether you use them or, whether they are paired,
etc.

So what is preventing people from using these new macros in the wrong way?

If I understand correctly, you have not read the discussion behind the
link I sent you... So in sum:
Initially, I only used the current ENTRY/ENDPROC approach and augmented
it to fix up the mess in x86. But it was concluded that these old macros
are terrible and we rather want to avoid them. It was especially the bad
naming of these old macros. So we discussed what the new naming scheme
could be and this is what we ended up with.

Obviously that they are impaired. That is the tools do not know where to
stop with reading of code or data.

This is quite usual:

foo:
  mov data,a
  call bar
  ret

data: .string "hello"

This makes the tools to choke on the data while thinking it is still code.

> So what is preventing people from using these new macros in the wrong way?

The tools. It is quite easy to check this during build by a linker and I
have such a patch here. It was not yet concluded (I think) whether we
are going to check this via objtool or by something like my patch.
Noteworthy, objtool can check much more in this respect, obviously.

thanks,

Sure, with v5, I will.

Thanks; that's much appreciated, and I look forward to it!
