Fwd: binutils in debian unstable is broken.

[Josh McKinney]

This seems to be a kernel bug which is shown with the new version of ld.  Thought I would
forward this along so maybe it can get fixed.

Yep, but this seems to be a real PIA to catch. Different .configs trigger
it differently and sometimes not at all. We're testing a couple patches at
the moment.

Earlier I stated incorrectly that it is a binutils bug; sorry for  
misleading information. Instead it seems Debian sid's latest binutils
package is much more strict.

It is a kernel bug, and it's going to break a truckload
of PCI drivers, along with uhci_pci_remove().

What is happening is this:  a typical driver has:

static void __devexit remove_foo(...)
{}

static struct pci_driver foo_driver = {
	...
	remove: remove_foo;
};

The problem is that if foo.c is statically linked into the
kernel, and if CONFIG_HOTPLUG is not set, __devexit evaluates
to __exit.  And in vmlinux.lds we've asked the linker to
discard all the contents of section .text.exit.

The problem appears to be that the linker is now actually doing what
we asked it to do, so the `remove_foo' entry in that table now points
at a function which isn't going to be linked into the kernel.  Oh dear.

Workarounds are:

1) Enable CONFIG_HOTPLUG

2) Change vmlinux.lds so we don't drop the .text.exit section (this
   is effectively the same as 1)

3) Something else.  HJ's #ifdef MODULE works OK.  It has a rather
   internecine relationship with the workings of __devexit though.

OK, here's a piece of speed-editing.  Fixed a few other __devexit
bugs on the way as well.

I didn't touch ISDN - the __devexit handling there is a bit complex,
and it needs a maintainer to go through it with the latest binutils.
They need to test with CONFIG_HOTPLUG on and off, modular and static.

All the rest of the kernel is done.  Could someone who has the
new binutils installed please test?

For older kernels the easiest fix is to edit your platform's
vmlinux.lds and just delete the /DISCARD/ section.

All right, working for me!
It seems I was suffering from the same problem, see my other post (Bug

Thanks a lot!

Thanks Andrew, you fixed it before I had the compulsion to compile a new
kernel.

I'm running 2.4.17-pre2+ext3-0.9.16+binutils now, and all is well so far.

The ideal it seems would be for binutils to support passing a stub function
to use in such cases. That would keep the kernel stuff working nicely and
allow us to do panic("__exit code called"); if anyone actually did manage
to call one.

In binutils? This sounds more like kernel should do it...
If all .text.exit functions were not static, it would be pretty easy to do,
but I guess they are usually static. In that case, I think it would take
about 1 day hacking an libelf program, which would rewrite all object files
which are going to be linked into vmlinux, which would add a new SHN_UND symbol to
each .symtab/.strtab (say __devexit_called) and change all relocs against
symbols in .text.exit sections to this symbol instead.
Maybe even it would take even less time, it is not that hard.

We can get a panic() call (and remove the ugly #ifdef's) with
something like this:

in some .h file:

#ifdef DEVEXIT_LINKED
#define DEVEXIT_FUNC(a) (a)
#else
void panic_exit_code();
#define DEVEXIT_FUNC(a) ((typeof((a)) *)panic_exit_code)
#endif

in some .c file:

#ifndef DEVEXIT_LINKED
void panic_exit_code()
{
   panic("__exit code called");
}
#endif


change the drivers like this:

#ifdef DEVEXIT_LINKED
     remove:         firestream_remove_one,
#endif

to this:

     remove:         DEVEXIT_FUNC(firestream_remove_one),

The overall situation is not great, but I think I prefer this, or
something like this, to the ifdef.

I'm tempted to say we should add a per-driver function that calls BUG()
instead of a generic function which calls panic(), though.  That will be
a bit more informative to users.  For the case where the real
xxx_remove_one is dropped, it is a kernel bug if that code is -ever-
called...

I definitely prefer this kind of encapsulation over #ifdef DEVEXIT_LINKED
everywhere, it's still ugly, though.

However, I don't see much advantage of panic_exit_code() over a simple
NULL. Actually, NULL will only oops, but not take the machine down, which
makes it easier to catch and report the Oops. (Not everyone who's box 
crashes under X will setup a serial console).
