Formally negative nice values have started become very big in positive
integers in -tip kernels:

I've just finished bisecting down to this commit:

commit 1427cdf0592368bdec57276edaf714040ee8744f
Author: Lai Jiangshan <***@cn.fujitsu.com>
Date: Fri Mar 6 17:21:47 2009 +0100

tracing: infrastructure for supporting binary record

Impact: save on memory for tracing

Current tracers are typically using a struct(like struct ftrace_entry,
struct ctx_switch_entry, struct special_entr etc...)to record a binary
event. These structs can only record a their own kind of events.
A new kind of tracer need a new struct and a lot of code too handle it.

So we need a generic binary record for events. This infrastructure
is for this purpose.

I find it hard to believe that this would cause normal nice values to be
messed up. The only file that could could come close to messing with nice
values in top is ftrace.h:


diff --git a/include/linux/ftrace.h b/include/linux/ftrace.h

extern int ftrace_arch_read_dyn_info(char *buf, int size);



And that too would be hard to affect nice values. Do you have a config
that I could test with?

Thanks,

Correct - maybe it's these two nearby commits that cause the
problems:

fef20d9: vsprintf: unify the format decoding layer for its 3 users
4370aa4: vsprintf: add binary printf

they do affect generic code. If we broke vsnprintf (which the
nice value output code uses) then that might be a plausible
explanation.

Thanks for this report Sitsofe. I have some ideas about the origin of this bug.
Anyway I'm in the middle of moving to another town. There are very good chances
that I send a fix tomorrow but not today.

Thanks.

OK I've just rebisected (and reverted) this down to the following:

commit fef20d9c1380f04ba9492d6463148db07b413708
Author: Frederic Weisbecker <***@gmail.com>
Date: Fri Mar 6 17:21:50 2009 +0100

vsprintf: unify the format decoding layer for its 3 users

An new optimization is making its way to ftrace. Its purpose is to
make trace_printk() consuming less memory and be faster.

Written by Lai Jiangshan, the approach is to delay the formatting
job from tracing time to output time.

Currently, a call to trace_printk() will format the whole string and
insert it into the ring buffer. Then you can read it on /debug/tracing/trace
file.

The new implementation stores the address of the format string and
the binary parameters into the ring buffer, making the packet more compact
and faster to insert.
Later, when the user exports the traces, the format string is retrieved
with the binary parameters and the formatting job is eventually done.

The new implementation rewrites a lot of format decoding bits from
vsnprintf() function, making now 3 differents functions to maintain
in their duplicated parts of printf format decoding bits.

Suggested by Ingo Molnar, this patch tries to factorize the most
possible common bits from these functions.
The real common part between them is the format decoding. Although
they do somewhat similar jobs, their way to export or import the parameters
is very different. Thus, only the decoding layer is extracted, unless you see
other parts that could be worth factorized.

Changes in V2:

- Address a suggestion from Linus to group the format_decode() parameters inside
a structure.

Changes in v3:

- Address other cleanups suggested by Ingo and Linus such as passing the
printf_spec struct to the format helpers: pointer()/number()/string()
Note that this struct is passed by copy and not by address. This is to
avoid side effects because these functions often change these values and the
changes shoudn't be persistant when a callee helper returns.
It would be too risky.

- Various cleanups (code alignement, switch/case instead of if/else fountains).

- Fix a bug that printed the first format specifier following a %p

Changes in v4:

- drop unapropriate const qualifier loss while casting fmt to a char *
(thanks to Vegard Nossum for having pointed this out).

Apologies for getting it wrong the first time round (I did say I hadn't
actually reverted the commit though ;)... The problem is that doing
blind bisection actually takes a large amount of time along with plenty
of reboots (additionally the makefile changed enough that oldconfig need
to have prompts answered in many cases) and I was trying to go as fast
as possible (I found the problem late in the evening and wanted to send
something before I fell asleep). Is there an IRC channel people testing
-tip hang out in? I tried #fedora-devel and #fedora-kernel but most of
the folks there were asleep or not testing -tip kernels.

(Forgot to cc lkml. Resending...)
Formally negative nice values have started become very big in positive
2 root 15 2147483647 0 0 0 S 0.0 0.0 0:00.00 kthreadd
The weird thing here is that number: 2147483647
It is 0xefffffff
Which means -1 without the highest bit (the sign).
I really don't know how it could have happened.

Anyway, I caught something in the signedness bits from my patch that unifies
the format decoding.
I've never seen your bug on my machine. But I note you have a 32 bits CPU.
Mine is 64 bits with a 64 bits kernel. Perhaps some weird signedness related things
happened because of the signedness bug that the following patch fixes.

Since there are no negative values in my dmesg, I did not catch this bug until now
(and my top output is normal).

Can you please give it a try?

Thanks a lot!

Subject: [PATCH] vsprintk: keep track of signedness

While unifying the format decoding, the sign flag has been dropped out in
favour of precise types (ie: LONG/ULONG).
But the format helper number() still needs this flag to keep track of the
signedness unless it will consider all numbers as unsigned.

Also add an explicit cast to int (for %d) while parsing with va_arg()
to ensure the highest bit is well extended on the 64 bits number that hosts the
value in case of negative values.

vsprintf: fix bug in negative value printing

Sitsofe Wheeler found and bisected that while unifying the
vsprintf format decoding in:

fef20d9: vsprintf: unify the format decoding layer for its 3 users

The sign flag has been dropped out in favour of
precise types (ie: LONG/ULONG).

But the format helper number() still needs this flag to keep track of
the signedness unless it will consider all numbers as unsigned.

Also add an explicit cast to int (for %d) while parsing with va_arg()
to ensure the highest bit is well extended on the 64 bits number that
hosts the value in case of negative values.
