Re: [PATCH] fixing sendfile on 64bit architectures

Re: [PATCH] fixing sendfile on 64bit architectures

[David Mosberger]

Andrew,

Below is a patch that tries to sanitize the dropping of unneeded
system-call stubs in generic code.  In some instances, it would be
possible to move the optional system-call stubs into a library routine
which would avoid the need for #ifdefs, but in many cases, doing so
would require making several functions global (and possibly exporting
additional data-structures in header-files).  Furthermore, it would
inhibit (automatic) inlining in the cases in the cases where the stubs
are needed.  For these reasons, the patch keeps the #ifdef-approach.

This has been tested on ia64 and there were no objections from the
arch-maintainers (and one positive response).  The patch should be
safe but arch-maintainers may want to take a second look to see if
additional __ARCH_OMIT_foo macros should be turned on for their
architecture (I'm quite sure that's the case, but I wanted to play it
safe and only preserved the status-quo in that regard).

Thanks,

	--david

IMHO this is exactly the wrong way around.  It should be __ARCH_WANT_*
or something like that so new architectures don't carry the old garbage
around by default.  There's far too many new architectures keeping old
syscalls by accident.

Feel free to do that.  I was trying not to break anything and I'm
_certain_ I would have gotten it wrong if I had reversed the sense.

I think the current patch is an improvement, so unless someone comes
up with something better, I'd like to see it applied.

I do agree that ARCH_WANT_FOO is easier to understand and more idiomatic.

An alternative might be to remove all the ifdefs, build with
-ffunction-sections and let the linker drop any unreferenced code...

That is true.  Actually, now that I have ARCH_OMIT, it's pretty easy
to write a script to do the complement, so the risk of introducing
errors is quite small.  Let me see what this looks like.

  Andrew> An alternative might be to remove all the ifdefs, build with

Yeah, that might be an option.  -ffunction-sections does bad things to
link-time, though, and I'm not sure I like the idea of having a
bazillion of tiny little sections.

Here is what the reversed-sense patch looks like (mostly autogenerated
via a script).  There are several platforms which do not drop any
syscalls.  If it's expected to stay that way, then it might make sense
to add asm-generic/unistd.h to collect the necessary #defines in a
single place.

	--david

Below is a patch that tries to sanitize the dropping of unneeded
system-call stubs in generic code.  In some instances, it would be
possible to move the optional system-call stubs into a library routine
which would avoid the need for #ifdefs, but in many cases, doing so
would require making several functions global (and possibly exporting
additional data-structures in header-files).  Furthermore, it would
inhibit (automatic) inlining in the cases in the cases where the stubs
are needed.  For these reasons, the patch keeps the #ifdef-approach.

This has been tested on ia64 and there were no objections from the
arch-maintainers (and one positive response).  The patch should be
safe but arch-maintainers may want to take a second look to see if
some __ARCH_WANT_foo macros should be removed for their architecture
(I'm quite sure that's the case, but I wanted to play it safe and only
preserved the status-quo in that regard).

That would probably be even more confusing than the #ifdefs.  At least with 
those you know that you need to check whether the current code will be 
called...

Me no understand Jesse.

Removing the ifdefs and letting the linker do the job has the advantage
that the compiler gets to check more code for you.

I think he meant that it's easier to see who (what platform) is
relying on the code.

Another disadvantage of -ffunction-sections is that the compiler won't
be able to do proper inlining.  There are several cases where you
have:

static
do_the_work ()
{
  ...
}

asmlinkage long
sys_one_variant ()
{
  do_the_work(some args...);
}

asmlinkage long
sys_other_variant ()
{
  do_the_work(other args...);
}

If only one variant is needed, GCC 3.4 will automatically inline
"do_the_work()" (since there is only one call-site), which is exactly
what you want.  You won't get that with -ffunction-sections.

Nevermind, I was confused about the patch.  I thought (without looking at it) 
that arch versions would be hidden in arch code, but now I see that they're 
just completely unused, so there's little chance for confusion.  I'll shut up 
now.

Great.

OK, looks like I failed to remove WANT_STAT64.

  Andrew> sparc64 is not happy:

Ah, __sparc__ is defined even for sparc64, makes sense, but I didn't
account for it.

The attached patch should have these fixed.

	--david

Below is a patch that tries to sanitize the dropping of unneeded
system-call stubs in generic code.  In some instances, it would be
possible to move the optional system-call stubs into a library routine
which would avoid the need for #ifdefs, but in many cases, doing so
would require making several functions global (and possibly exporting
additional data-structures in header-files).  Furthermore, it would
inhibit (automatic) inlining in the cases in the cases where the stubs
are needed.  For these reasons, the patch keeps the #ifdef-approach.

This has been tested on ia64 and there were no objections from the
arch-maintainers (and one positive response).  The patch should be
safe but arch-maintainers may want to take a second look to see if
some __ARCH_WANT_foo macros should be removed for their architecture
(I'm quite sure that's the case, but I wanted to play it safe and only
preserved the status-quo in that regard).

That builds OK on ia32, sparc64, ppc64 and, I assume, ia64.

x86_64 has a problem in ipc/util.c:

	int ipc_parse_version (int *cmd)
	{

comes out as

	int 0x0100
	{

due to:

#if defined(__ia64__) || defined(__x86_64__) || defined(__hppa__)
  /* On IA-64, we always use the "64-bit version" of the IPC structures.  */ 
# define ipc_parse_version(cmd)	IPC_64
#else
int ipc_parse_version (int *cmd);
#endif

Good (yes, I tested ia64).

OK, I had failed to drop __ARCH_WANT_IPC_PARSE_VERSION for x86-64.  I
rechecked now to make sure there weren't any other x86-64 omissions.
As far as I can see, it _should_ be OK now, but Andi may want to
double-check anyhow to see if there are other things that could be
dropped.

	--david

Below is a patch that tries to sanitize the dropping of unneeded
system-call stubs in generic code.  In some instances, it would be
possible to move the optional system-call stubs into a library routine
which would avoid the need for #ifdefs, but in many cases, doing so
would require making several functions global (and possibly exporting
additional data-structures in header-files).  Furthermore, it would
inhibit (automatic) inlining in the cases in the cases where the stubs
are needed.  For these reasons, the patch keeps the #ifdef-approach.

This has been tested on ia64 and there were no objections from the
arch-maintainers (and one positive response).  The patch should be
safe but arch-maintainers may want to take a second look to see if
some __ARCH_WANT_foo macros should be removed for their architecture
(I'm quite sure that's the case, but I wanted to play it safe and only
preserved the status-quo in that regard).

I am not sure if it will handle EXPORT_SYMBOL correctly. Sometimes
we have the situation that a function is only referenced from EXPORT_SYMBOL,
but we do not want the linker to drop it because modules may use it.
(this regularly causes problems in lib-y files) 

If it did it would be great to use though. I am sure there are other
dead functions around too. Or maybe someday we could even use the 
IPA functionality in gcc 3.4 ...
