Hi everybody, I just joined the LKML!

Don't worry, this is not just a test message, I do actually have 
something to say. I just compiled 2.6.11-rc5-mm1 and got undefined 
symbols "match_int", "match_octal", "match_token", and "match_strdup" in 
several modules. This is using binutils 2.15 and gcc 3.4.4 from Debian.
I grepped around and found those functions in lib/parser.c, so I just 
looked at the output of "make V=1" and invoked "ld" manually, adding in 
lib/lib.a, and the modules work fine now. However, I don't know enough 
about the kernel build process to make a patch to fix this, so I'm just 
notifying people of the problem.

BTW, I just got a new hard disk and put Reiser4 on it. It works great! 
Keep up the good work guys!

I have the exact same problem. 
.config is attached
(this may be a debian specific problem as I'm running debian too)

Regards,

Vincent

OK, there are no vmlinux references to lib/parser.o's symbols.  So it isn't
getting linked in.

In lib/Makefile, remove parser.o from the lib-y: rule and add

obj-y	+= parser.o

That much I figured out after Vincent sent his bug report two weeks ago.

This I didn't find.

Is it really the intention to silently omit objects that are not 
referenced or could this be changed?

Why doesn't an EXPORT_SYMBOL create a reference?

In some cases, yes, it it desirable.  For example, lib/extable.c provides a
default implementation of an exception table sorter but if the architecture
defies its own, the linker will skip the default version in lib/.

At least, that's what the thinking was a few years ago.  But it's such a
special-case that we can probably forget about it and just drive the build
and linkage with config now.

>  Why doesn't an EXPORT_SYMBOL create a reference?

It does, but that reference is within the same compilation unit as the
definition.  IOW: there are no references to the symbol which are external
to the symbol's file.   There's still nothing to drag that file in.

I just got bit by a similar issue myself last night.  Had a working 2.6.11-rc5-mm1 tree
compiled with gcc 3.4.  Then Fedora-devel had an update to gcc 4.0, so I
rebuilt the *same exact tree* with it, and it threw 3 errors at me, for
exit_orinoco() in drivers/net/wireless/orinoco.c and init_hermes() and exit_hermes()
in drivers/net/wireless/hermes.c.  Here's what the code looked like:

(hermes.c)
static int __init init_hermes(void)
{
        return 0;
}

static void __exit exit_hermes(void)
{
}

module_init(init_hermes);
module_exit(exit_hermes);

That's it.  As far as I can tell, gcc 4.0 semi-correctly determined they were both
static functions with no side effect, threw them away, and then the module_init
and module_exit threw undefined symbols for them.

My totally incorrect workaround was to stick a printk(KERN_DEBUG) in the body
of the 3 trimmed functions so they had side effects.

Anybody got a *better* solution?

uh, maybe

static int __init init_hermes(void)
{
	asm("");
	return 0;
}

then raise a gcc bug report?

As a module, we create a non-static alias for "init_hermes", called
"init_module", effectively making it non-static.  GCC should not
eliminate it in this case.  Similar with module_exit().

For non-modules, we have __attribute_used__.

lib/extable.c already uses two ARCH_HAS_* defines, simply because the 
linker couldn't help if only one of two functions in a file were needed.

It does: EXPORT_SYMBOL(x) drops the address of "x", including
__attribute_used__, in the __ksymtab section.

However, if CONFIG_MODULES=n, it does nothing: perhaps that is what you
are seeing.

That's not the problem.

And it has nothing to do with any gcc 4.0 issues mentioned in this 
thread - I saw this problem with gcc 3.3 .

Try the attached .config in 2.6.11-rc4-mm1 (not in 2.6.11-mm1).

Well, the problem is that this is still an internal reference in the same 
object file. So ld looks into the lib .a archive, determines that none of 
the symbols in that object file are needed to resolve a reference and 
drops the entire .o file. Doing so, it drops the __ksymtab section as 
well, which otherwise would be used by the kernel to look up that symbol. 

So it drops the reference and the referencee ;), which is normally fine -- 
no unresolved symbols occur. Unfortunately, the kernel really needs to 
know the contents of the __ksymtab sections to correctly export those 
symbols, but it doesn't reference it in any explicit way.

I don't think there's an easy fix, except for not putting such objects 
into an archive/lib, but to link them directly.

Silly question:
What's the advantage of lib-y compared to obj-y?

Basically exactly what I quoted above -- unused object files don't get
linked into the kernel image and don't take up (wasted) space. On the
other hand, files in obj-y get linked into the kernel unconditionally.

And this can break as soon as the "unused" object files contains 
EXPORT_SYMBOL's.

Is it really worth it doing it in this non-intuitive way?
I'd prefer an explicite dependency on a variable if you want to 
compile library functions conditionally.

I don't think it non-intuitive, it's how libraries work. However, as you 
say, it is broken for files containing EXPORT_SYMBOL.

The obvious fix for this case is the one that akpm mentioned way earlier 
in this thread, move parser.o into $(obj-y).

It should be rather easy to have the kernel build system warn you when you 
compile library objects exporting symbols.

This warning sounds like a good plan (but it won't let many objects stay 
inside lib-y).

The patch is simple (except that the warning it throws looks rather ugly), 
see appended.

However, I spoke too soon. There actually is a legitimate use for 
EXPORT_SYMBOL() in a lib-y object, e.g. lib/dump_stack.c. This provides a 
default implementation for dump_stack(). Most archs provide their own 
implementation (and EXPORT_SYMBOL() it), and in this case we definitely 
want the default version in lib to be thrown away, including its 
EXPORT_SYMBOL. So the appended patch throws false positives and thus can 
not be applied.

Still, many files in lib-y "should" be moved to obj-y. Then again, the 
clear cases (e.g. ctype, vsnprintf) are getting used in the static kernel 
image, so they get linked in anyway, moving them from lib-y to obj-y 
doesn't make any difference whatsoever.

The interesting cases are more of the crc32 type -- some people may not 
use this at all, so they want the space savings. Moving all of those into 
obj-y unconditionally creates unnecessary bloat. Actually, crc32 already 
did the right thing -- a config option. That would work for parser.o, too, 
just make the filesystems which need it "select CONFIG_PARSER".

I think there are basically three cases of objects in lib-y:

o functions we clearly use anyway, e.g. vsprintf.o.
  these should be always available, also for modules (pretty much every
  module uses printk, right?)
  So these should be in obj-y, however since they always get used in the
  kernel, too, independent of the .config, in practice there's no 
  difference to them being in lib-y.
o "weak" implementations, which may be overwritten by a arch-specific
  implementation.
  These need to be in lib-y for this mechanism to work.
o Marginal cases like crc32.o, parser.o, bitmap.o
  There are real world cases out there where these functions will never be 
  used, so just compiling them into the kernel because one day there may 
  be a module which wants to use them does cause some bloat. Making them
  config options and have every module which needs them mention them in
  Kconfig causes some bloat on the source side.
  It's a trade-off. In my tree (current -bk), parser.o symbols are
  referenced by procfs, i.e. 99.9% of all builds will pull it in anyway.
  So putting it into obj-y is a good solution, IMO. (Do I hear the 
  embedded people cry?)
  I guess in -mm this changed, which may justify going to CONFIG_PARSER
  (along the lines of CONFIG_CRC32) way. Then again, .text of
  parser.o is 0x373 bytes on my x86_64 system. Not a whole lot to
  lose when it's compiled in unconditionally. (And it's used among others 
  by ext2 and ext3, so chances are, you need it anyway)

That's usually solved through #define's (see e.g. lib/extable.c).

It's used by many filesystems plus some optional part of the USB code.

Basically, there are two choices:
- always include a function
- include a function only if required

The second one is possible, but object files are the wrong granularity - 
why should it pull the whole parser.c if only match_strdup was required?

You have all possibilities with #define's.

Agreed.

This doesn't work if the object file also contains other code.

Can you send a .config where bitmap.o isn't used?

As above:
If you care about code size, CONFIG_PARSER gives the wrong granularity.



My general impression is:

Everything lib-y does can be done with obj- and #define's.
And this way, it's done explicit.

I'm not really happy with tricks like compiling two versions of 
dump_stack() and the linker somehow discards the right one.

Well, you can obviously solve pretty much everything with #define's, but 
it's usually also the ugliest solution.

>From my point of view, the preferences for solving issues like the 
extable.c one are:

o Do it automatically. If the architectecture defines its own version, use
  that one -- otherwise use the default.
o Take care of it by configuration options.
  Let the arch have CONFIG_GENERIC_EXTABLE_SORT (or not), and use that to
  determine whether to compile / link sort_extable()
o Use a #define / #ifdef in the source file to conditionally compile 
  things.

Having a config option has the advantage that one can do

	obj-$(CONFIG_GENERIC_EXTABLE_SORT) += extable_sort.o

which leaves the source code free of ugly #ifdef's. Obviously that only 
works if extable.c is split into extable_sort.o and extable_search.o. If 
one goes that step (fine IMO), one can however just add these files to 
lib-y, i.e. use the first solution - everything happens automatically, no 
need for ARCH_ defines, no need for new CONFIG options.

Yes, object files are not necessarily the right granularity -- in fact, 
traditionally libraries are composed of object files which pretty much 
follow a "one function per file" principle, to get this right.

However, two cases should be distinguished:

o providing a default implementation. Obviously, this one needs separate 
  files for separately needed units (like the extable.c example above)
o providing a library functionality. Grouping multiple functions together
  isn't necessarily wrong, it just may cause slight inefficencies (pulling
  in unneeded code). I really don't think we want to go to one function 
  per file but rather leave things grouped as they currently are. If 
  someone needs match_strdup, they'll pull in all of parser.o.

> You have all possibilities with #define's.

Yes, but also all the ugliness. There's a trade-off where the optimal 
smallest binary kernel image comes with a bloated, unreadable, full of 
'#ifdef' kernel source. Noone wants that. If you can optimize the binary 
kernel image in some automated way with little impact on the source code, 
that's fine. Otherwise, you'll give up a little space savings for easier 
maintainability.

> If you care about code size, CONFIG_PARSER gives the wrong granularity.

Going more fine-grained is out of the question, IMO. If anything, going 
less fine-grained, i.e. include all of parser.o unconditionally is the way 
to go here. Currently, the only more fine-grained way would be to have 
ext2 in KConfig CONFIG_MATCH_INT, CONFIG_MATCH_TOKEN. FAT would define
CONFIG_MATCH_INT, CONFIG_MATCH_TOKEN, CONFIG_MATCH_OCTAL, etc. That's 
insanity.

> Everything lib-y does can be done with obj- and #define's.
> And this way, it's done explicit.

That's true. But more often than not, we don't care about explicitness,
we care about cleanliness and readability. The ugliness is hidden 
somewhere, in includes, in Kconfig, in the build system. "module_init()" 
is very non-explicit, it does completely different things depending on 
whether a file is compiled into a module or the kernel. But we sure prefer 
the cleanliness of module_init() over having #ifdef's in each module which 
explicitly what happens.

As I said it's all a trade-off, and it has much to do with taste. Code 
looking clean is important. However, hiding too much and jumping through 
hoops just so that something looks clean while all the magic happens 
somewhere deep inside unbeknowst to all but few gurus isn't right, either.

This discussion doesn't really have much to do with the original issue 
anymore. Move parser.o to obj-y and be done with it -- in reality everyone 
needs it, anyway. EXPORT_SYMBOL() sometimes and kinda unpredictably not 
working in lib-y is tricky. But it produces obvious errors, unresolved 
symbols, not obscure un-debuggable bugs.
