In environment
- Host: kernel-2.6.32xxx (RHEL6)
- Guest: mm-of-the-moment snapshot 2011-02-04-15-15
I saw this when I ran make -j8 under 200M limit of memcg with 4vcpu.
But it seems this doesn't directly related to memcg or virtualization.
Anyway, log is here. I'm sorry if this is a fixed one.
My .config is attached. and a brief note is below

2nd log, "kernel BUG at include/linux/mm.h:420!" is This one.

static inline void __ClearPageBuddy(struct page *page)
{
VM_BUG_ON(!PageBuddy(page));
atomic_set(&page->_mapcount, -1);
}

But this is just a tail of bad_page().
==
static void bad_page(struct page *page)
{
static unsigned long resume;
static unsigned long nr_shown;
static unsigned long nr_unshown;
...
dump_stack();
out:
/* Leave bad fields for debug, except PageBuddy could make trouble */
__ClearPageBuddy(page);
add_taint(TAINT_BAD_PAGE);
}

So, what important is bad_page().
BAD page says

Maybe page_mapcount(page) was > 0. and ->mapping was NULL.
BTW, I think pc->flags should be printed in hex...Nishimura-san, how do you think ?
In hex, pc->flags was 7A00000000004 and this means PCG_USED bit is set.
This implies page_remove_rmap() may not be called but ->mapping is NULL. Hmm?
(7A is encoding of section number.)
make -j 8 under 200M limit is highly busy with swap.
Thanks,

Thanks so much for looking into it. There is a separate little issue here, Andrea. Although we went to some trouble for bad_page() to take the page out of circulation yet let the system continue, your VM_BUG_ON(!PageBuddy) inside __ClearPageBuddy(page), from two callsites in bad_page(), is turning it into a fatal error when CONFIG_DEBUG_VM. You could that only MM developers switch CONFIG_DEBUG_VM=y, and they would like bad_page() to be fatal; maybe, but if so we should do that as an intentional patch, rather than as an unexpected side-effect ;) I noticed this a few days ago, but hadn't quite decided whether just to remove the VM_BUG_ON, or move it to __ClearPageBuddy's third callsite, or... doesn't matter much. I do also wonder if PageBuddy would better be _mapcount -something else: if we've got a miscounted page (itself unlikely of course), there's a chance that its _mapcount will be further decremented after it has been freed: whereupon it will go from -1 to -2, PageBuddy at present. The special avoidance of PageBuddy being that it can pull a whole block of pages into misuse if its mistaken. Hugh ^ permalink raw reply [flat|nested] 14+ messages in thread

I see what you mean. Of course it is only a problem after bad_page already triggered.... but then it trigger an BUG_ON instead of only a bad_page. > You could that only MM developers switch CONFIG_DEBUG_VM=y, and they > would like bad_page() to be fatal; maybe, but if so we should do that > as an intentional patch, rather than as an unexpected side-effect ;) Fedora kernels are built with CONFIG_DEBUG_VM, all my kernels runs with CONFIG_DEBUG_VM too, so we want it to be as "production" as possible, and we don't want DEBUG_VM to decrease any reliability (only to increase it of course). > I noticed this a few days ago, but hadn't quite decided whether just to > remove the VM_BUG_ON, or move it to __ClearPageBuddy's third callsite, > or... doesn't matter much. > > I do also wonder if PageBuddy would better be _mapcount -something else: > if we've got a miscounted page (itself unlikely of course), there's a > chance that its _mapcount will be further decremented after it has been > freed: whereupon it will go from -1 to -2, PageBuddy at present. The > special avoidance of PageBuddy being that it can pull a whole block of > pages into misuse if its mistaken. Agreed. What about the below? ===== Subject: mm: PageBuddy cleanups From: Andrea Arcangeli <aarcange@redhat.com> bad_page could VM_BUG_ON(!PageBuddy(page)) inside __ClearPageBuddy(). I prefer to keep the VM_BUG_ON for safety and to add a if to solve it. Change the _mapcount value indicating PageBuddy from -2 to -1024 for more robusteness against page_mapcount() undeflows.

I doubt the more expensive checks are very measurable.. benchmarks usually run on enterprise distro. I'm sure when they enabled, they were aware of having to run more expensive runtime checks. > But the patch actually says -1024*1024: either would do. I actually increased it to -1024*1024 after writing the email ;) sorry the for the confusion. > Yes, that's fine, 0xfff00000 looks unlikely enough (and my > imagination for "deadbeef"-like magic is too drowsy today).

Ok the reason I didn't move the VM_BUG_ON is to be stricter in case there are more usages of __ClearPageBuddy in the future. I guess it's not so important, but when I initially implemented it, it wasn't entirely obvious it would work safe with memory hotplug, compaction and all other bits using PageBuddy, so... ^ permalink raw reply [flat|nested] 14+ messages in thread
