LinuxLists.cc - Inconsistent kallsyms data (since 2.6.11-rc3 or so)

Subject: Inconsistent kallsyms data (since 2.6.11-rc3 or so)

One of my m68k configs has been giving

| Inconsistent kallsyms data
| Try setting CONFIG_KALLSYMS_EXTRA_PASS

since 2.6.11-rc3 or so. Setting CONFIG_KALLSYMS_EXTRA_PASS, or applying Keith
Owen's patch to fix an issue for SH
(http://seclists.org/lists/linux-kernel/2005/Jan/0017.html) doesn't help.

The diffs between the human-readable tables (as generated by Keith's
kallsyms_uncompress.pl) show lots of changes (see below).

Related config settings:

| anakin$ grep kallsyms .config
| CONFIG_KALLSYMS=y
| # CONFIG_KALLSYMS_ALL is not set
| CONFIG_KALLSYMS_EXTRA_PASS=y
| anakin$

Any other info that's needed to solve this issue? Thanks!

There is something weird going on here.

For starters all the symbols that move are of type either '?'(unknown
type) or 'b' (local bss).

From the first to the second run a few more symbols pop up, and that
moves symbols around. From a quick visual inspection I spotted these:

> +b log_start PTR 0x1b72c8
> +b con_start PTR 0x1b72cc
> +b log_end PTR 0x1b72d0

There might be a few more, but these would be enough to give problems.

Although marked as 'b' type, their addresses are between _sinittext and
_einittext. These are actualy "local bss", static vars defined in printk.c.

So the question is: why don't they appear on the first link phase on m68k?

This is either a toolchain bug or an error in vmlinux.lds for m68k.
Sections are overlapping in the .tmp_vmlinux files. Merging the output
from objdump -h and nm into a single map and using type '0' as the
start of a section clearly shows that .bss, .data.cacheline_aligned and
.init.text are overlapping. .bss variables (types b and B) appear
after the start of .data.cacheline_aligned, and even after the start of
.init.text.

kallsyms flags an error because some of the .bss variables are moving
from .data.cacheline_aligned to .init.text between pass 1 and 2. That
changes the set of KALLSYMS symbols between pass 1 and 2, which trips
the verification bug. This is not a kallsyms bug, it is an m68k
toolchain problem, kallsyms is just picking it up.

Patch for generating this map is in a separate mail.
