Omar probably won't wake up in quite a while, so I've tested the patch.
Alas, doesn't help.  Similar spew (for the few modules I don't have =y),
while reverting 784d5699eddc fixes it for me too.

Forgot to engage my brain before posting.

Architectures will need to have an include/asm/asm-prototypes.h that
defines or #include<>s C-style prototypes for exported asm functions.
We can do an asm-generic version for the common ones like memset so
there's not a lot of pointless duplication there.

Care to do a patch for x86?

Thanks,
Nick

Sure, did so.  With the prototypes added, your patch works!
Tested on a handful of modules, and one out-of-tree (virtualbox).
I didn't try a 32-bit build.

Note that powerpc already has an include/asm/asm-prototypes.h which might or
might not be what you want.  It doesn't have memset and co, for example.

Anyway, here's my stab at x86:

Before too late, those extern keywords aren't needed and

It is easy to obtain. Here is top 10 with runtime bigger than 0.50%:

_int_malloc
ht_lookup_with_hash
_cpp_lex_direct
cpp_get_token_1
ggc_internal_alloc_statm
_int_free
malloc_consolidate
lex_identifier
enter_macro_context
c_lex_with_flags
bitmap_set_bit
malloc
grokdeclarator
htab_find_slot_with_hash
c_lex_one_token
_cpp_lex_token
pop_scopev
c_parser_declspecs

Imagine you're a compiler. Those extern's are tokens. They need to be parsed
(byte-by-byte), allocated, and, in case of "extern" with prototype, thrown away.
They make line longer forcing people to dance around with splitting
per 80 characters
and generally making everything somewhat slower. Might as well don't new ones.

bitops.h is wrong header as well.
Why do you need bitops for bunch of function prototypes?

Well you can't use asm/arch_hweight.h in a generic header of course.
I would suggest just including linux/ variants where practical for
the asm-generic/asm-prototypes.h header.

We should probably just bring all these arch patches through the
kbuild tree.

I'm sorry for the breakage: I didn't realize it broke the build with
some configs, otherwise I would have given Michal a heads up before
his pull request, and worked to get this stuff in first.

Thanks,
Nick

It breaks with some binutils versions only (and only with
CONFIG_MODVERSIONS=y, of course).

Yeah this seems to be the issue, it apparently slipped past all the
automated builds. It seems like the existing CRC warnings in the tree
only trigger in rare circumstances too, so something could be a bit
fragile there.

I upgraded from 4.8 to 4.9-rc2 and noticed that kernel modules fail to
load (log below). After investigating for some time I found this thread
and apparently this is not still fixed, at least not in Linus' tree.

Reverting 784d5699eddc5 fixed the issue for me. As I don't see any fix
available (please correct me if I'm wrong) we should just revert that
commit until it's properly fixed.

Also note that there's a related fix from Steven:

[PATCH] x86: Fix export for mcount and __fentry__
https://marc.info/?l=linux-kernel&m=147733572502413

For compiling the kernel I'm using Ubuntu 12.04:

ii  gcc                  4:4.6.3-1ubuntu5     GNU C compiler

The kernel is running on a separate machine with Ubuntu 14.04.

With these two patches together, does it work for you?

http://marc.info/?l=linux-arch&m=147653546809512&w=2
http://marc.info/?l=linux-kernel&m=147669851906489&w=2

It would be helpful if you could test and let us know, because there seems
to be a very tiny number of configs and toolchains that causes problems.

I haven't seen that one before. Did you definitely make and install new
modules?

With these two patches (on top of ath-201610251249 from ath.git, in
practice 4.9-rc2 + latest wireless patches) module loading works again.
If you want you can add my Tested-by:

Tested-by: Kalle Valo <kvalo@codeaurora.org>

Can we get these patches to Linus' tree soon? It's annoying to revert
784d5699eddc5 everytime I update my tree.

I'm pretty sure modules are correctly installed as I have used the same
procedure for years: on my workstation I do 'make bindeb-pkg', copy the
.deb to the test laptop and install the deb there. Also once I revert
784d5699eddc5 it starts immeadiately working.

Yes I think it's about ready to merge. Michal is returning from vacation
next week so we should get some progress soon.

Many thx.

I added this report to the list of regressions for Linux 4.9. I'll
watch this thread for further updates on this issue to document progress
in my weekly reports. Please let me know via regressions@leemhuis.info
in case the discussion moves to a different place (bugzilla or another
mail thread for example).

Current status (afaics): Fix available, waiting for Michal to get back
from vacation.

tia! Ciao, Thorsten

Adam,

are you submitting a new version of your x86 asm-prototypes.h patch?

I believe inclusion of <linux/bitops.h> is the right thing to do, but if
not, the patch would also need:

extern unsigned int __sw_hweight8(unsigned int w);
extern unsigned int __sw_hweight16(unsigned int w);
extern unsigned int __sw_hweight32(unsigned int w);
extern unsigned long __sw_hweight64(__u64 w);


There's also the issue of mcount/__fentry__, but that's apparently already
dealt with in 5de0a8c, already in mainline.

> are you submitting a new version of your x86 asm-prototypes.h patch?

The update is trivial, but yeah, I can resubmit.  If I'm wrong about where
__sw_hweight{8,16,32,64} should come from, please say so.

I am not sure what you mean? The kernel is rpm-ized 4.9 vanilla and this
is the config:

Most of us get just a scary-looking warning, but whatever the problem is for
you, it's good to hear this patch works around it.

Whatever the long-term solution will be, for 4.10 an updated[1] version of
this fix is on kbuild/kbuild (and kbuild/for-next).  I guess we'll bother
stable@ once it is merged.

Note that it handles only x86, there's a bunch of other architectures
affected, alpha m68k s390 sparc ia64 might still need fixing.

[1]. Turns out there was a missing symbol on 486; people build-test those
but don't try to actually boot, and even when they do, they don't read
warnings.

This makes no sense.

mcount isn't even one of the symbols that the patch by Adam is touching.

There's something else screwed up here. Not to mention that others
don't have your issue.

Do you have some other hacks in this area? Are you testing actual
plain 4.9, or do you (for example) still carry Arnd's patch around
that turned out to not work (reverted by f27c2f69cc8e in my tree)?

asm-prototypes.h in his patch includes asm/ftrace.h, where the function
is declared. That should be enough IIUC scripts/Makefile.build.

I suppose people don't run i386 kernels or have different config.

Not at all. This was plain 4.9 packaged by suse -- only rpm-related
fixes. I tried plain 4.9 without rpm right now with the same output:
# insmod soundcore.ko
[   31.582326] soundcore: disagrees about version of symbol mcount

I hit an mcount issue a while back (years?) which was due to building a
driver with gcc v4.x while kernel was built using gcc v4.y. Not claiming
that is your issue though.

I've usually had the same thing happen to me if things were compiled
with different gcc versions . Essentially in newer gcc (starting with
4.6 I believe) CC_USING_FENTRY is defined, meaning that there is no
mcount() symbol but rather __fentry__. This is the likely problem here.

No, it is not. How could a rpm be built with two compilers?

Moreover, with some modules, __put_user_1 and others are reported
instead of mcount.

What do these report ? I bet you that in your vmlinux the first one
would return something like :

ffffffff822f1810 T __fentry__
ffffffff827fdc20 r __kcrctab___fentry__
ffffffff82809461 r __kstrtab___fentry__
ffffffff827e6c20 R __ksymtab___fentry__

Well, I have just won a beer:
$ nm vmlinux | grep mcount
         w __crc_mcount
c0b3bd34 r __kcrctab_mcount
c0b41692 r __kstrtab_mcount
c0b2dd04 R __ksymtab_mcount
c0896130 T mcount

c0cba89c T __stop_mcount_loc
$ nm vmlinux | grep __fentry__
$ nm sound/soundcore.ko | grep mcount
         U mcount

No, I am really not stupid. We compile the kernels like this for over a
decade and it really broke with 4.9. Applying the patch fixes the
problem. Reverting it, makes it recur.

[PATCH] kbuild: provide include/asm/asm-prototypes.h for ARM

[Arnd Bergmann]

This adds an asm/asm-prototypes.h header for ARM to fix the
broken symbol versioning for symbols exported from assembler
files.

In addition to the header, we have to do these other small
changes:

- move the 'extern' declarations out of memset_io/memcpy_io
  to make them visible to the symbol version generator
- move the exports from bitops.h to {change,clear,set,...}bit.S
- move the exports from csumpartialgeneric.S into the files
  including it

I couldn't find the correct prototypes for the compiler builtins,
so I went with the fake 'void f(void)' prototypes that we had
before.

Hi Arnd,

just to make sure I'm looking at the right code - is this based on the
patch by Nick here: https://patchwork.kernel.org/patch/9377783/?

Correct.  I had imported Nick's patch into my randconfig tree and
this is what I needed to build all configurations cleanly with it.

I'm not in favour of this.

   +extern void mmioset(void *, unsigned int, size_t);
   +extern void mmiocpy(void *, const void *, size_t);
   +
    #ifndef __ARMBE__
    static inline void memset_io(volatile void __iomem *dst, unsigned c,
           size_t count)
    {
   -       extern void mmioset(void *, unsigned int, size_t);
           mmioset((void __force *)dst, c, count);
    }

The reason they're declared _within_ memset_io() is to prevent people
from using them by hiding their declaration.  Moving them outside is
an open invitation to stupid people starting to use them as an "oh it
must be an official API".

We know this happens, there's been a long history of this kind of stupid
in the ARM community, not only with cache flushing APIs, but also the
DMA APIs.

The way the existing code is written is a completely valid way to hide
declarations from outside the intended caller's scope.

We've been here many times, we've had many people doing this crap, so
I'm now at the point of NAKing changes which result in an increased
visibility to the rest of the kernel of symbols that should not be
used by stupid driver authors.

Now, why do we have these extra functions when they're just aliased to
memset()/memcpy() - to avoid GCC optimising them because it thinks that
they're standard memset()/memcpy().

So overall this gets a NAK from me.

Now, it would have _ALSO_ been nice to have been at least COPIED on the
original set of changes that caused the need for this change.  I wasn't.
So I want to see the original set of changes reverted, because they're
clearly causing breakage.  Let's revert them and then go through the
proper process of maintainer review, rather than bypassing maintainers
and screwing up architectures in the process.  There really is no
excuse for this crap.

Fair point, what about leaving those as they are, and also adding
them to asm-prototypes.h protected with GENKSYMS ifdef? It's not
beautiful, but still better than armksyms.c before Al's patches (or
at least no worse).

You may have a point about improvement of the process. I wasn't
involved in the original patches, but we did cc linux-arch when the
.S CRC issue became known.

However let's work on the assumption that they won't be reverted at this
stage, and try to come up with something to fix it that you're happy with.

Nick

I disagree (also see below).  The armksyms way was understandable.
The new way... I've no idea yet, because I wasn't even copied on
any of the patches.  I've no idea how the exports are now handled.
I'm in a black hole with respect to that, and that's now a problem.

Yes, but I'm not on linux-kernel-v2, and I've no desire to end up with
another list I've no hope of keeping up with to my mailbox - I'll just
ignore it.  99% of the messages on it at the time when vger kicked me
off the list was x86 related discussion, and not really cross-arch
issues.  As I say, it just became another linux-kernel list.

Well, there's more problems with this new KSYMS approach than just the
CRCs.  It forces a rebuild of the ksyms files every single time, which
then causes a relink of the kernel:

New way is you put the EXPORT_SYMBOL in the .S file, and give it a C
style prototype in asm-prototypes.h, and that's it. The build system
will do the rest. Either way you require some file of C prototypes,
but after Al's patches, at least the EXPORT goes with its definition.

As far as rebuilding too often, that sounds like a bug, more below.

For the patches that touched arm code, I'd agree you should have been cc'ed.

Not to dismiss that concern at all, but for issues of interest to arch code
but not specific to any (such as discovery that the asm exports change would
require this change to restore CRC generation), I was just saying linux-arch
is most appropriate for better or worse. Ccing 30 arch lists is not workable.

And again not to dismiss your concern, I'm just here trying to come up with
a workable fix for the non-revert scenario. Revert is no less valid an
option, it's just not one I'm in favour of myself.

Good catch, I'm surprised you're the first one who reported it. This patch
seems to do the trick for me:

Thanks for testing it.

Hopefully if Arnd is able to respin the ARM patch to something a bit more
to your liking that doesn't expose prototypes, and no other problems arise,
we can avoid reverting. You had a poor first impression, but we may yet win
you over.

I've split out that change from the other ones now, and will follow
up with the patch to address all the other ones first.

I'm trying this one, and an alternative patch that moves the
export into arch/arm/kernel/io.h. Let's see if we can agree
on one of these.

[PATCH 1/2] kbuild: provide include/asm/asm-prototypes.h for ARM

[Arnd Bergmann]

This adds an asm/asm-prototypes.h header for ARM to fix the
broken symbol versioning for symbols exported from assembler
files.

In addition to the header, we have to do these other small
changes:

- move the exports from bitops.h to {change,clear,set,...}bit.S
- move the exports from csumpartialgeneric.S into the files
  including it

I couldn't find the correct prototypes for the compiler builtins,
so I went with the fake 'void f(void)' prototypes that we had
before.

This leaves the mmioset/mmiocpy function for now, as it's not
obvious how to best handle them.

This looks nicer. I like variant B because it keeps the GENKSYMS cruft to
a single location, but either one isn't too bad.

I'd like to get moving on this, so let's at least get the generic kbuild
change merged. In the end, the kbuild code does not prevent a maintainer
from putting their EXPORT_SYMBOL in whatever location they like, so there
is no reason not to merge it (certainly there will be archs that do use
it).

Michal, what's your thoughts? If you merge my patch 2/2 and skip 1/2, it
should not give any new build warnings or errors, so then arch patches can
go via arch trees. 1/2 could go in after everyone is up to date.

Thanks,
Nick

So what's the conclusion on this?  I've just had a failure due to
CONFIG_TRIM_UNUSED_KSYMS reported on ARM, and it looks like (at
least some of) patch 1 could resolve it.

Do we need to split patch 1?

Has any of these patches been committed yet?

Hmm. I've got

Hmm, those seem to have gone in during the last week, so I haven't
tested it yet (build running, but it'll take a while).  However, I
don't think they'll solve _this_ problem.

Some of the issue here is that we use a mixture of assembly macros
and preprocessor for the ARM bitops - the ARM bitops are created
with an assembly macro which contains some pre-processor expanded
macros (eg, EXPORT_SYMBOL()).

This means that the actual symbol being exported is not known to
the preprocessor, so doing the "__is_defined(__KSYM_##sym)" inside
"EXPORT_SYMBOL(\name)" becomes "__is_defined(__KSYM_\name)" to the
preprocessor.  As "__KSYM_\name" is never defined, it always comes
out as zero, hence we always use __cond_export_sym_0, which omits
the symbol export from the assembly macro definition:

 .macro bitop, name, instr
.globl \name ; .align 0 ; \name:

...

.type \name, %function; .size \name, .-\name

 .endm

In other words, using preprocessor macros inside an assembly macro
may not work as expected, and now leads to config-specific failures.

Yes, that's a limitation. cpp expansion we can handle, but not gas macros.
You will need Arnd's patches for ARM.

http://marc.info/?l=linux-kbuild&m=147732160529499&w=2

If that doesn't fix it for you, send me your .config offline and I'll set
up a cross compile to work on it.

Again, any arch always has the option of going back to doing asm exports
in the old style of putting them into a .c file, but hopefully you'll find
Arnd's reworked patches to be something you're willing to merge.

Nick

	WARNING: "memset" [drivers/media/usb/airspy/airspy.ko] has no CRC!

and booting the resulting kernel failed with messages of the type:

	[    3.029107] usbcore: Unknown symbol __memzero (err -22)

so hardly any module could be loaded. modprobe -f works however, but
that's not what my initramfs does.

With this patch and https://patchwork.kernel.org/patch/9392291/ ("ARM:

CRC warnings and it boots fine. So it would be great to get these two

Yea, many things would be nice, but I've been unable to track the
issues here - it really didn't help _not_ being copied on the
original set of patches which introduced this mess.

I've merged Nicolas' patch, so now we need to work out what to do
with the remaining bits - which I guess are the asm-prototypes.h
and the mmio* bits.  I'm not aware of what's happening with the
patches that they depend on (which is why I recently asked the
question - again, I seem to be completely out of the loop due to
lack of Cc's).

So I'm just throwing my hands up and saying "I don't know what to
do" at this stage.

Quick overview:

- asm exports changes allow EXPORT_SYMBOL to be moved into .S files,
  but they would not get modversion CRCs generated.

- The core kbuild patches to add modversions support for asm exports
  is now merged in Linus's tree from the recent kbuild tree pull.
  asm/asm-prototypes.h must contain C style declarations of the symbol
  for this to work.

- Architectures can now add their asm/asm-prototypes.h and things
  *should* start working.

- Dependency is not a hard one. If you add asm-prototypes.h before
  merging the core patches then it should not introduce any problems.

I don't think you have missed much since last it came up, it's just
taken a bit of time to get the details right and get it merged.

Not sure what your tree looks like, but if you merge this patch 1/2
plus 2a/2 or 2b/2 into upstream, then ARM should be working.

[PATCH 2/2, variant A] ARM: add hidden mmioset/mmiocpy prototypes

[Arnd Bergmann]

The prototypes for mmioset/mmiocpy are intentionally hidden
inside of inline functions, which breaks the EXPORT_SYMBOL
statements when symbol versioning is enabled.

This adds a prototype to asm/asm-prototypes.h but hides it
in an #ifdef so normal drivers don't see it and won't be
able to abuse the interface.

[Arnd Bergmann]

The prototypes for mmioset/mmiocpy are intentionally hidden

This moves the two exports from the files that implement the
code into the kernel/io.c file, adding another local declaration
there.

If they're not intended for public use, they should (also) be prefixed
with "__" or even "____" to make this clear.

Tried that with the __cpuc_* cache flushing interfaces.  It doesn't

[GIT PULL] kbuild changes for v4.9-rc1

[Michal Marek]

Hi Linus,

please pull these kbuild changes for v4.9-rc1:

- EXPORT_SYMBOL for asm source by Al Viro. This does bring a regression,
  because genksyms no longer generates checksums for these symbols
  (CONFIG_MODVERSIONS). Nick Piggin is working on a patch to fix this.
  Plus, we are talking about functions like strcpy(), which rarely
  change prototypes.
- Fixes for PPC fallout of the above by Stephen Rothwell and Nick Piggin
- fixdep speedup by Alexey Dobriyan.
- Preparatory work by Nick Piggin to allow architectures to build with
  -ffunction-sections, -fdata-sections and --gc-sections
- CONFIG_THIN_ARCHIVES support by Stephen Rothwell
- Fix for filenames with colons in the initramfs source by me.


The following changes since commit 29b4817d4018df78086157ea3a55c1d9424a7cfc:

So this has broken all module loading for me. I get the following dmesg
spew:

...
[    4.586914] scsi_mod: no symbol version for memset
[    4.587920] scsi_mod: Unknown symbol memset (err -22)
[    4.588443] scsi_mod: no symbol version for ___preempt_schedule
[    4.589026] scsi_mod: Unknown symbol ___preempt_schedule (err -22)
...

Reverting 784d5699eddc ("x86: move exports to actual definitions") fixes
it for me. This is with GCC 6.2.1, binutils 2.27, attached config.

Thanks for the report. Could you try this patch and see if it helps?


Allow architectures to create asm/asm-prototypes.h file that
provides C prototypes for exported asm functions, which enables
proper CRC versions to be generated for them.

It's done by creating a trivial C program that includes that file
and the EXPORT_SYMBOL()s from the .S file, and preprocesses that
then sends the result to genksyms.

Hi,

>> it for me. This is with GCC 6.2.1, binutils 2.27, attached config.

I've had the same problem. Reverting your binutils from 2.27 to 2.26,
will also fix it. It seems ld 2.27 is not merging weak symbols from .o
files to vmlinux when linking.

Anyhow all crc for symbols exported from .S will be 0, so Nicholas
patch make sense.
