#1322004 — [RFC][PATCHSET] allowing exports in *.S

FromAl Viro <viro@ZenIV.linux.org.uk>

Subject[RFC][PATCHSET] allowing exports in *.S
Message-ID<qWmKl-7Pd-9@gated-at.bofh.it>
	The policy wrt exports right now is "put it next to the definition
of object being exported, unless it's in assembler".  The reasons for having
an export near the definition are obvious - it's easier to keep things
in sync that way, the fact that function can be called by modules is
obvious without grepping through the entire tree, etc.

	The major exception is for things defined in assembler - exports
of those are kept in arch/*/*/*ksyms*.c.  The reason is that EXPORT_SYMBOL
and friends can't be used from assembler; all the reasons to keep them
with definitions still apply, but we simply can't do that.

	Another unpleasant issue is that lib-y objects need to be careful
about their exports - it *is* done in quite a few places, but it's only
legitimate as long as any .config either doesn't include any modules
using a symbol in question _or_ has built-in users of something from the
same object.  For something like ctype.c the latter is a safe bet, but
something more subtle can suddenly get into trouble years later when
such a config becomes possible - the lack of built-in users ends up with
linker not picking the object at all, which leads to missing export.
As the result, we have things like "here's a long series of lib-y,
with that object in the middle going into obj-y" with no indication of the
reasons why *and* nothing to guarantee that we won't need the same treatment
for other objects there.

	It is connected to the former, since quite a few *.S that contain
exported functions happen to be in lib-y.

	This series (available in vfs.git#work.asm-exports) introduces
a new header (asm/export.h), to be included from *.S and defining variants
of EXPORT_SYMBOL and EXPORT_SYMBOL_GPL usable there.  It also allows
safe exports from lib-* - any object that contains an export after it's
been compiled gets automatically pulled into vmlinux.

	The only real restriction left is that if you have a weak symbol,
exporting it from the same object file will forcibly peek _that_ definition,
even if the symbol itself is overridden by another alternative at link time.

The first patch allows to export safely from lib-*, the second one adds
asm-generic/export.h, usable as-is for almost all architectures.  The only
exceptions are 64bit x86, which wants unusually strong alignment for
struct kernel_symbol and m68k, which wants only 16bit alignements for pointers
(and for struct kernel_symbol as well).  Such an architecture can add
asm/export.h that defines a couple of macros (KSYM_ALIGN and KCRC_ALIGN)
and includes <asm-generic/export.h>.  Normally you only need to add
generic-y += export.h to asm/Kbuild; of course, if you don't put any exports
into asm files, you don't need to do anything at all.

The rest of that series is mostly proof-of-concept "let's take exports on
<architecture> to the matching definitions" for a bunch of architectures;
it's more of a demonstration that it can be done - any given architecture
might prefer to add convenience macros, etc.  This is just adding includes
of asm/export.h and moves EXPORT_SYMBOL/EXPORT_SYMBOL_GPL to *.S.  Usually
it ends up with arch/*/*/*ksym*.c gone.

A bunch of detritus had been found and removed in process - e.g. exports of
static inline, functions that had lost both in-tree callers and export, but
forgotten and left behind, etc.  I'm fairly sure that more junk like that
is out there; that's one of the reasons why exports really ought to be near
the definitions...

Of course, we don't have to move all exports at once (or move them at all);
it's not a flagday conversion.  The whole series so far can be picked at
git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs.git work.asm-exports;
I'll post individual patches in followups.

Please, review and comment.

#1322005 — [PATCH 02/12] EXPORT_SYMBOL() for asm

FromAl Viro <viro@ZenIV.linux.org.uk>
Date2016-01-29 20:20 +0100
Subject[PATCH 02/12] EXPORT_SYMBOL() for asm
Message-ID<qWmKl-7Pd-11@gated-at.bofh.it>
In reply to#1322004
From: Al Viro <viro@zeniv.linux.org.uk>

Add asm-usable variants of EXPORT_SYMBOL/EXPORT_SYMBOL_GPL.  This
commit just adds the default implementation; most of the architectures
can simply add export.h to asm/Kbuild and start using <asm/export.h>
from assembler.  The area where the things might diverge from default
is the alignment; normally it's 8 bytes on 64bit targets and 4 on
32bit ones, both for unsigned long and for struct kernel_symbol.

Unfortunately, amd64 and m68k are unusual - m68k aligns to 2 bytes
(for both) and amd64 aligns struct kernel_symbol to 16 bytes.  For
those we'll need to have asm/export.h overriding the constants used
by generic version (KSYM_ALIGN and KCRC_ALIGN for kernel_symbol and
unsigned long resp.) and including asm-generic/export.h.

And no, __alignof__ would not do the trick - on amd64 __alignof__
of struct kernel_symbol is 8, not 16.

#1322008 — [PATCH 01/12] [kbuild] handle exports in lib-y objects reliably

FromAl Viro <viro@ZenIV.linux.org.uk>
Date2016-01-29 20:20 +0100
Subject[PATCH 01/12] [kbuild] handle exports in lib-y objects reliably
Message-ID<qWmKm-7Pd-23@gated-at.bofh.it>
In reply to#1322004
From: Al Viro <viro@zeniv.linux.org.uk>

Collect the symbols exported by anything that goes into lib.a and
add an empty object (lib-exports.o) with explicit undefs for each
of those to obj-y.

That allows to relax the rules regarding the use of exports in
lib-* objects - right now an object with export can be in lib-*
only if we are guaranteed that there always will be users in
built-in parts of the tree, otherwise it needs to be in obj-*.
As the result, we have an unholy mix of lib- and obj- in lib/Makefile
and (especially) in arch/*/lib/Makefile.  Moreover, a change in
generic part of the kernel can lead to mysteriously missing exports
on some configs.  With this change we don't have to worry about
that anymore.

#1322017 — [PATCH 05/12] m68k: move exports to definitions

FromAl Viro <viro@ZenIV.linux.org.uk>
Date2016-01-29 20:30 +0100
Subject[PATCH 05/12] m68k: move exports to definitions
Message-ID<qWmU3-7SX-37@gated-at.bofh.it>
In reply to#1322004
From: Al Viro <viro@zeniv.linux.org.uk>

the rest of architectures should just use generic-y += export.h in
asm/Kbuild

Looks good, and (some of, not all) the symbols end up in kstrtab, so

Acked-by: Geert Uytterhoeven <geert@linux-m68k.org>

Note that none of the m68k defconfigs build modules that refer to these
symbols. This changes completely with allmodconfig, which adds lots of
references in many of the same modules.
CONFIG_LBDAF=y is set in the defconfigs.

Unfortunately I haven't managed to boot a kernel that uses these symbols
in modules...

The kernel has all the *di3 variants:

002eae2c T __ashldi3
002eae70 T __ashrdi3
002eaebc T __lshrdi3
002eaf00 T __muldi3
0038a6d0 R __ksymtab___ashldi3
0038a6d8 R __ksymtab___ashrdi3
0038ab68 R __ksymtab___lshrdi3
0038ab90 R __ksymtab___muldi3
003a8a5a r __kstrtab___ashldi3
003a8a64 r __kstrtab___ashrdi3
003a8a6e r __kstrtab___lshrdi3
003a8a78 r __kstrtab___muldi3

Hence the *si3 are missing:

__divsi3
__modsi3
__mulsi3
__udivsi3
__umodsi3

Does your .config have CPU_HAS_NO_MULDIV64?  Because otherwise these objects
won't be built and their exports had been conditional on that as well:

#if defined(CONFIG_CPU_HAS_NO_MULDIV64)
/*
 * Simpler 68k and ColdFire parts also need a few other gcc functions.
 */
extern long long __divsi3(long long, long long);
extern long long __modsi3(long long, long long);
extern long long __mulsi3(long long, long long);
extern long long __udivsi3(long long, long long);
extern long long __umodsi3(long long, long long);

EXPORT_SYMBOL(__divsi3);
EXPORT_SYMBOL(__modsi3);
EXPORT_SYMBOL(__mulsi3);
EXPORT_SYMBOL(__udivsi3);
EXPORT_SYMBOL(__umodsi3);
#endif

is what we have in mainline m68k_ksyms.c.  Neither allmodconfig, nor any of
defconfigs have it.  And on a coldfire build they are built and exported as
expected:
$ grep si3 ../build/coldfire/System.map 
002be860 T __divsi3
002be890 T __modsi3
002be8b8 T __mulsi3
002be8dc T __udivsi3
002be90c T __umodsi3
003ed960 R __ksymtab___divsi3
003edc80 R __ksymtab___modsi3
003edca8 R __ksymtab___mulsi3
003edff8 R __ksymtab___udivsi3
003ee000 R __ksymtab___umodsi3
003f7ba4 r __kcrctab___divsi3
003f7d34 r __kcrctab___modsi3
003f7d48 r __kcrctab___mulsi3
003f7ef0 r __kcrctab___udivsi3
003f7ef4 r __kcrctab___umodsi3
004144fe r __kstrtab___divsi3

Oh, I hadn't actually noticed that dependency.
No, CPU_HAS_NO_MULDIV64 is not set, as I handle the parts with MMU only.
