Hi
I have an Ultra 5 (360MHz, 256MB) with kernel 2.6.25.4 and I see userspace
process crashes when I run kernel compiled with preempt. The crashes
happen once in few hours, a good test for them is to compile kernel in a
loop --- the crashes happen in cc1 or as.
- I didn't saw any crash with no preemption or voluntary preemption (run
it full loaded for a week, it is stable)
- The kernel doesn't crash, just userspace processes crash.
- Preemptible RCU has no effect on the crashes (they happen with or
without it)
- The debug options in "kernel hacking" report nothing when enabled, but
with the options enabled, the crashes happen more often
Presumably, there is some point where preemption corrupts userspace
process state, do you have any idea where it could be? You can send me any
patches to test. Send them directly to my email, I'm not on the list.
BTW. I saw another problem --- when I compile kernel with 64kB pages, it
crashes on load (it doesn't even switch to Linux console) ... is it known
problem?

Thanks for the report, I remember you mentioning this at
LinuxTAG the other day.

It's known to be broken. I simply suggest that people not try
to use such esoteric features until I have a lot of time to
try and either make them work or remove them.

I'm going to start looking into this now, thanks for report.

I think the FPU state is being corrupted by the kernel.
The FPU is used heavily by memcpy and memset in userspace
and therefore FPU corruption shows up as either strange
behavior or outright crashes in userspace.

BTW. two years ago, I reported a bug that userspace programs on sparc64
would randomly crash in a few hours with preempt enabled
( http://marc.info/?l=linux-sparc&m\x121222607414906&w=4 )
Now I tried the same workload with 2.6.35 and it is stable with preempt.
Are you aware that the bug was fixed? Or if not, it may be still lurking
there and some unrelated change hid the race condition. Should I bisect
the kernel to find out which patch actually fixed (or hid) the bug?

I can't think of anything we did explicitly to fix that.
I'm sure you can find more useful things to do than to try and
bisect that thing down, really :-)

From my experience with development --- no race should be silently
ignored. Because if you ignore a race, there is a possibility that the
race is still lurking there, only hitting under different conditions.
I did the bisect anyway, the race was fixed between 2.6.28 and 2.6.29-rc1.
Here "bad" really means "doesn't have a bug" and "good" means "does have
the bug", because bisect tool was written to search for bugs that were
created, not fixed. "X" means "doesn't work, I guessed".

I very much don't understand the bisect tool, I thought that it will do a
binary search between the entries in the ChangeLog file, but it skips very
randomly (the second columnt is the line in the ChangeLog file).
How does it really work? Do you know how to interpret it and which patch
really fixed the bug?

When there are multiple lines of development, it has to hop in and out
of the merged branches.
Sometimes that aspect can make it go "out of order".
The best you can do is do the full bisect, trust what it comes up
with, and start your analysis with the commit it comes up with after
the whole bisect is complete.
What commit did it print out when you completed the bisect run?
Also, there is another problematic case, sometimes bisect gives you
a merge commit. And this means that in the tree in which the
development of the branch was done, the bisect condition doesn't
trigger, but once it gets integrated into what happened upstream
meanwhile, it does trigger.

Bisecting over a graph, that is totally confusing.

I don't know what came up. The last "good" one and the last "bad" one are
more than 1000 lines apart. After these tries it refused to bisect
further and pretended that the bug is found.
If you can't interpret it --- there happened sparc+sparc64 -> sparc merge
between this and it looks like a probable cause. Could you give me your
git tree with linear commits that I could try?

I rebase my tree every time the merge window completes, so
I can't give that to you, sorry.
But you don't need my tree from back then, you can git bisect between
the commits on my line of development branch when Linus pulled my tree
in.
And even my original tree was linear, I would pull Linus's tree in now
and again to deal with merge conflicts and similar.
Anyways, all the information is there, you just need to give GIT the
properl commit ranges.
BTW, if you're so disappointed about how it walks the graph during git
bisect, feel free to suggest alternatives to the GIT developers. I
think they considered long and hard about this, and therefore the
current behavior isn't arbitrary :-)

I assume that there was some commit ID in your tree when you started to do
sparc+sparc64 unification and there was some commit ID when you finished
it. So give me these two and I hope git will go linearly between them.

If you understand git better than me, please explain to me how to
interpret bisect result --- i.e. I sent a list of commit IDs that are
result of bisecting, so tell me which fixed the bug and how did you find
it.

Maybe not this specific portion, but some parts of the unification
work was not done linearly, it was partly done in a GIT tree
maintained by Sam Ravnborg and partly done in mine.
Non-linear development is just how things are much of the time.
And regardless, you could figure out the commits you're looking for by
looking in GITK at the merge commit when Linus brought the my tree in
during the merge window, walk up the line that represents my branch going
back in time to the point where the line connects back up to the mainline.
Start with something like "gitk v2.6.28..v2.6.29-rc1 -- arch/sparc arch/spar64"
it's pretty clear what the sequence of commits are in that branch when you
look at that window.
The boundaries (inclusive) you come up with will be something like:
4696b64d234b84b5b70ffd49a76833aa5c49cb61
86821d18f9d8fd42fa3180ad3703d491aecc52d9
Btw, "git bisect visualize" uses gitk to show you where the good and
bad points are in the graph during bisection.
