As of 2.6.18-rc3, one of my test machines stopped booting. I'm not
seeing the whole OOPS (I could probably set up a serial console if
necessary), but it ends in something like:
trace_hardirqs_on
idesci_pc_intr
ide_intr
handle_IRQ_event
__do_IRQ
do_IRQ
common_interrupt
default_idle
apm_cpu_idle
cpu_idle
rest_init
start_kernel
0xc0100199
DWARF2 unwinder stuck at 0xc0100199
Leftover inexact backtrace:
=======================
BUG: unable to handle kernel paging request at virtual address 0000b034
printing eip:
c0103712
*pde = 00000000
Recursive die() failure, output suppressed
<0>Kernel panic - not syncing: Fatal exception in interrupt
Bisecting, it looks like this starts happening after c97d20a...,
"[PATCH] i386: Do backtrace fallback too", though it's a little tricky
since the compile is broken near there for a little while.
Kernel config appended; let me know if anything else would be useful.
--b.

I think there were some unwinder fixes post-2.6.18-rc3.
We need to work out what's causing this oops asap, please. Testing
2.6.8-r4-git1 (which should be available within the day) would be useful,
please. If it crashes, it'll be serial console time.

The 'stuck' unwinder issue at hand already has a fix, though planned to
be merged for 2.6.19 only. The crash after switching to the legacy
stack trace code is bad, though, but has little to do with the unwinder
additions/changes. The way that code reads the stack is just
inappropriate in contexts where things must be expected to be broken.
Finally, there is no visible correlation between the original problem (in
or from trace_hardirqs_on) and the unwinder - once that problem is
fixed, you're not likely to see the recursive die failure anymore either.

I'm seeing the same behavior on Linus's latest as of this morning
(2.6.18-rc4-gef7d1b24). Is there something else I should be testing?

The stuck is expected, but the unable to handle paging request should be
fixed. If not then it's a different problem than what I'm thinking,
but it looks very similar.

OK, so any suggestions for what I should try?
My most recent panic on boot ended with:
DWARF2 unwinder tack at 0xc0100199
Leftover inexact backtrace:
=======================
BUG: unable to handle kernel paging requets at virtual address 0000b034
printing eip:
c0103712
*pde = 00000000
Recursive die() failure, output suppressed
<0>Kernel panic - not syncing: Fatal exception in interrupt
Taking a look at an "objdump -d vmlinux", that c0103712 is in
show_trace_log_lvl():
...
c01036f9: e8 a2 33 01 00 call c0116aa0 <printk>

...
It looks like that's the deference of context on line 221:
stack = (unsigned long*)context->previous_esp;
So "context" was 0000b000?? OK, I don't know this code at all, so I'm
probably not going to figure out anything useful here.

"merged for 2.6.19" meaning:
- in (before) 2.6.19, or
- after 2.6.19 is released
If "after," then it will likely need to be added to -stable also,
so it might as well go in "before" 2.6.19 is released.

Precisely.
Guys, this unwinder change has been quite problematic. We really cannot
let this badness out into 2.6.18 - it degrades our ability to debug every
subsystem in the entire kernel. Would marking it CONFIG_BROKEN get us back
to 2.6.17 behaviour?
Has anyone even tried to reproduce Bruce's crash?
<looks>
argh, ide-scsi. That driver's main use nowadays is for testing the
oops-handling code. Please share .config, machine description and compiler
versiom.

My understanding of 'for' is that Andi will send to Linus after in the 2.6.19
merge window.

I'd prefer pushing into 2.6.18 some of the patches currently scheduled for
2.6.19 over marking it CONFIG_BROKEN. But that's clearly not my decision.

IMHO just some stucks is tolerable for .18 and .18-stable, as long as it doesn't
add new crashes and the fallback always gives an useful backtrace (that is why I
added the fallback -- to make sure no information is lost)
Short term the stucks are a bit ugly but I hope with .19 or .20 longer
term we will have much better backtraces without false positives
(ok assuming people turn it on). The code queued for .19 should
be already pretty good now (ok after I fixed one nasty problem yesterday
that added some new ones compared to .18)

I looked at it a bit, but it puzzles me. The chaining for the interrupt stacks
on i386 -- which is what seems to be corrupted here -- shouldn't have changed at all
by the unwinder changes.
I suspect it would crash without unwinder too. Bruce, do you get the
same crash when you boot with "call_trace=old" ?

Not necessarily:
if (UNW_SP(&info))
stack = (void *)UNW_SP(&info);
is rather fragile - the minimum extra protection here should be to only use
UNW_SP() for the continuation stack pointer if it actually points into kernel
space (as is being done in one of the 2.6.19 patches), ...
>I suspect it would crash without unwinder too. Bruce, do you get the

... but of course I continue to agree that doing things like
addr = *stack++;
in the legacy stack trace code cannot be good, given that this code
generally is expected to run when things are already bad in some way.

Hmm, which patches did you want? I got a double digit number of unwind
related patches already, some of them quite intrusive, and all of them would be clearly
too much. My preference for 2.6.18 would be really only absolutely critical stuff
because I'm paranoid of breaking more.

I was thinking of the fixes to the fallback logic and the bottom-of-stack annotations.

After appending "call_trace=old" to the boot commandline, and it booted
succesfully. It had the following warning at what I suspect was the
same place the boot stopped before:

I actually have no idea why I've got that turned on. I've probably been
updating that same .config for years. (Mind if I just turn it off, or
are the bug reports useful?)
> Please share .config, machine description and compiler versiom.
gcc --version says "4.1.2 20060814 (prerelease) (Debian 4.1.1-11)".
I'm not sure what to give you for a machine description. I've appended
the output of lspci and the start of a dmesg from a succesful boot, if
that helps, followed by the .config.

the patch below should get rid of the warning above.

Subject: lockdep: annotate idescsi_pc_intr()
From: Ingo Molnar <[email protected]>
idescsi_pc_intr() uses local_irq_enable() in IRQ context: annotate it.
(this has no effect on kernels with lockdep disabled. On kernels with
lockdep enabled this means that we wont actually disable interrupts,
and the warning message will go away as well.)

I double checked this now again and I think Jan's patch
ftp://ftp.firstfloor.org/pub/ak/x86_64/late-merge/patches/backtracer-stuck-in-apic_timer_interrupt
should fix it. I plan to submit that one for 2.6.18

I get into few "unwinder" issues - see following 2 cases.
(nothing really stopping my work). It gives me *useful* stacks
than before - so no major complaints :)
I know that you are working on some of the unwinder fixes for
2.6.19 - just want to let you know about my problems also :)

I submitted Jan's patch to fix that one for .18, but Linus hasn't merged it
yet.

Hmm, not sure about that one. In theory it should have been fixed
in rc4 already. Was this from an earlier kernel?

Hi,
I just read that unwinder thread and I think I have yet another case of
unwinder backtrace that comes up together with the recursive deadlock
protection backtrace and this happens with 18-rc5 so I thought I should
report it before .18 is released:

Unfortunately this leaves unclear whether there was anything reported in
the leftover portion.
And in all cases, a sufficiently long raw stack trace is needed to analyse this.
Ideally a matching System.map would also be attached.

Actually, that's all there was in dmesg. System.map is at

Borislav, if you can reproduce the crash please boot with kstack=2048 and send output
of that.

Sorry,
but this patches x86_64 arch and mine is i386. I could change the
kstack_depth_to_print from 24 to 2048 in
linux/arch/i386/kernel/traps.c by hand instead but I don't have
a _show_stack function there, do I? Or maybe that is not at all necessary to see a
"proper" stack dump?

I ran into another (small) issue with the trace - it looks like
for some reason trace repeats twice. Do you know, why ?

I assume you mean the fallback validation fix. Linus unfortunately
didn't merge any of my new patches yet :/
But did you ever work out why the stack backtrace completely restarted?
I never got this. In theory the RSP gotten out of the unwind
context and used for the fallback should have been already near the end
and the old unwinder shouldn't have found much.
-Andi
P.S.: Badari, we worked out your kernel_math_context trace too:
that one is actually a gcc bug related to dubious unwind tables generated
for noreturn calls (in your case do_exit). We were still discussing the best
workaround for that one.

To follow myself up. I should have checked HEAD before writing this :/
Linus merged it all last night and I blamed him wrongly, sorry.
So that problem will be hopefully gone.
For completeness the unwind fixes that went in were:
Jan Beulich [PATCH] x86: Make backtracer fallback logic more bullet-proof
Andi Kleen [PATCH] i386: Add kernel thread stack frame termination
Andi Kleen [PATCH] x86_64: Add kernel thread stack frame termination
and this one fixed an additional bug in the old x86-64 unwinder:
Keith Owens [PATCH] x86_64: Save original IST values for checking

Actually, the same patch, but other pieces of it ...

In the old (up to -rc5) code, we had
if (unw_ret > 0 && !arch_unw_user_mode(&info)) {
< all the fallback handling>
}
with no else, thus just falling through (without even changing the
stack pointer, which was wrong when unw_ret > 0 but we reached
a user mode address (i.e. as in the example here, after unwinding
out of a syscall frame).

I will verify them when I get a chance to move to latest kernel.
Unfortunately, so called testcases are the *real* problems I am
trying to track down in 2.6.18-rc4 and I have a setup/config/testcase
which can reproduce them consistently. I don't want to change
any kernel/config till I debug these issues. Once I figure out whats
happening - I will move to latest and verify one more time.
BTW, I have one more issue - may not be related to unwinder. As
you can see when I get a assert on CPU1, I get its stack correctly.
But CPU 2 is getting stuck while printing OOPS.
Do you know, why ?
Thanks,
Badari

Sorry I just meant the problem has been analyzed, but not fixed
yet (it is a bit tricky). Most of the fixes won't make 2.6.18
anyways because it's too late for that.

Don't know why sorry, but it seems to be indeed before the unwinder.
Maybe some state got messed up completely.

Andi,
I am looking at the "validity" of the stack traces. What I
find is that "unwinder" is skipping few stack frames..
As you can see from the following stack - it shows
msync_interval() ->
set_page_dirty() ->
__set_page_dirty_buffers()
But actual trace is (looking at the code):
msync_interval() ->
msync_page_range() ->
msync_pud_range() ->
msync_pgd_range() ->
msync_pte_range() ->
set_page_dirty() ->
__set_page_dirty_buffers()
Why is it skipping all msync_page/pud/pgd/pte_range() routines ?
Thanks,
Badari

Most likely because they're inlined. gcc tends to always inline static functions
with only a single caller, which is usually true for all the nested page table functions
in mm/*. Inlined functions (or tail called functions like return foo()) are invisible
to the unwinder.

Sometimes this is caused by tail calls, i.e. when the last line
of a function calls another function it can many times be optimized
into a jump.
You can disable this by compiling with CONFIG_FRAME_POINTER=y.

Even that will not disable automatic inlining, which is probably causing most
of the missing frames here.

Lots of luck. I logged a bug several years ago against gcc for ia64
with noreturn calls. When gcc sees a call to a function marked
noreturn (like do_exit or panic), gcc has been known to discard all
code past that point. The unwind code has to assume that the return
address is pointing into the previous function. Where does the return
address point after a noreturn call compiled with the gcc bug? - at
the start of the next function. Goodbye unwind.
I asked that gcc always insert at least one instruction after a call to
a noreturn function. That would keep the return address inside the
right function and the unwind code would work. Ideally that
instruction would cause an error if it was ever executed (break 0 on
ia64, ud2 on i386/x86_64) but even a no-op would be good enough. Most
of the ia64 list thought it was a good idea, the gcc team disagreed.
AFAIK the bug is still outstanding.

In the discussion Jan came up with a heuristic that will probably work.
It involved deciding in the unwinder by heuristic if it should subtract
one from the program counter (like the gcc unwinder apparently does) or not.
He hasn't sent a patch implementing it yet though :)
