Have you ever seen such a race? I do not see how this could happen. mem_cgroup_force_empty_list is called only from mem_cgroup_force_empty_write (aka echo whatever > group/force_empty) or mem_cgroup_pre_destroy when the group is destroyed. The initialization code is, however, called before a group is given for use AFICS. I am not saying tha the change is bad, I like it, but I do not think it is a fix for potential race condition. > > Signed-off-by: Igor Mammedov <imammedo@redhat.com> > --- > mm/memcontrol.c | 2 +- > 1 files changed, 1 insertions(+), 1 deletions(-) > > diff --git a/mm/memcontrol.c b/mm/memcontrol.c > index bd9052a..ee7cb4c 100644 > --- a/mm/memcontrol.c > +++ b/mm/memcontrol.c > @@ -4707,7 +4707,6 @@ static int alloc_mem_cgroup_per_zone_info(struct mem_cgroup *mem, int node) > if (!pn) > return 1; > > - mem->info.nodeinfo[node] = pn; > for (zone = 0; zone < MAX_NR_ZONES; zone++) { > mz = &pn->zoneinfo[zone]; > for_each_lru(l) > @@ -4716,6 +4715,7 @@ static int alloc_mem_cgroup_per_zone_info(struct mem_cgroup *mem, int node) > mz->on_tree = false; > mz->mem = mem; > } > + mem->info.nodeinfo[node] = pn; > return 0; > } > > -- > 1.7.1 > > -- > To unsubscribe from this list: send the line "unsubscribe linux-kernel" in > the body of a message to majordomo@vger.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html > Please read the FAQ at http://www.tux.org/lkml/ -- Michal Hocko SUSE Labs SUSE LINUX s.r.o.

Hmm, I have missed that cgroup_create calls create callback for all subsystems that the group should be attached to. But this shouldn't be any problem as cgroup_call_pre_destroy (called from cgroup_rmdir) cannot be called before the directory is actually created. cgroup_create_dir is called after cgroup has been created for all subsystems so the directory entry will show up only after everything is initialized AFAICS. So I still do not see how we can race. Anyway, if you are able to reproduce the problem then I would say that the problem is somewhere in the generic cgroup code rather than in memory controler. The patch just papers over a real bug IMO. But I may be wrong as I am not definitely an expert in the area. > > >>Signed-off-by: Igor Mammedov<imammedo@redhat.com> > >>--- > >> mm/memcontrol.c | 2 +- > >> 1 files changed, 1 insertions(+), 1 deletions(-) > >> > >>diff --git a/mm/memcontrol.c b/mm/memcontrol.c > >>index bd9052a..ee7cb4c 100644 > >>--- a/mm/memcontrol.c > >>+++ b/mm/memcontrol.c > >>@@ -4707,7 +4707,6 @@ static int alloc_mem_cgroup_per_zone_info(struct mem_cgroup *mem, int node) > >> if (!pn) > >> return 1; > >> > >>- mem->info.nodeinfo[node] = pn; > >> for (zone = 0; zone< MAX_NR_ZONES; zone++) { > >> mz =&pn->zoneinfo[zone]; > >> for_each_lru(l) > >>@@ -4716,6 +4715,7 @@ static int alloc_mem_cgroup_per_zone_info(struct mem_cgroup *mem, int node) > >> mz->on_tree = false; > >> mz->mem = mem; > >> } > >>+ mem->info.nodeinfo[node] = pn; > >> return 0; > >> } > >> > >>-- > >>1.7.1 -- Michal Hocko SUSE Labs SUSE LINUX s.r.o.

No yet. But vanilla has the same code and down the road may dereference invalid 'pc' variable too. That's why I posted patch here, theoretically OOPS could happen. > Or at least try it with fce66477 (just a blind shot). We have this commit. It's probably another problem. The trouble manifests itself here: mem_cgroup_force_empty_list: pc = list_entry(list->prev, struct page_cgroup, lru); when list->prev == 0 we have invalid 'pc' pointer => crash >> EIP: 0060:[<c05235b3>] EFLAGS: 00010206 CPU: 0 >> EIP is at mem_cgroup_force_empty+0x123/0x4a0 >> EAX: 00000206 EBX: fffffff4 ECX: c0a3f1e0 EDX: 00000206 >> ESI: 00000206 EDI: 00000000 EBP: f343ca00 ESP: f34e7e84 >> DS: 007b ES: 007b FS: 00d8 GS: 00e0 SS: 0068 >> Process cgclear (pid: 2300, ti=f34e6000 task=f35baab0 task.ti=f34e6000) >> Stack: >> ffffffff 00000001 00000000 f34e7eb8 00000100 00000000 c0a3f1e0 c05a5af5 >> <0> f343ca00 f343cc00 00000000 00000000 00000000 00000000 00000000 00000000 >> <0> c0a3e7c0 f35172c0 00000005 00000000 f35172d0 f35baab0 00000000 f35172c0 >> Call Trace: >> [<c05a5af5>] ? may_link+0xc5/0x130 >> [<c049b246>] ? cgroup_rmdir+0x96/0x3f0 >> [<c0473f20>] ? autoremove_wake_function+0x0/0x40 >> [<c05339ce>] ? vfs_rmdir+0x9e/0xd0 >> [<c0536806>] ? do_rmdir+0xc6/0xe0 >> [<c0506702>] ? do_munmap+0x1f2/0x2c0 >> [<c04adecc>] ? audit_syscall_entry+0x21c/0x240 >> [<c04adbe6>] ? audit_syscall_exit+0x216/0x240 >> [<c0409adf>] ? sysenter_do_call+0x12/0x28 >> Code: 89 7c 24 20 8b 54 95 08 31 ff 89 44 24 14 81 c2 00 01 00 00 89 54 24 10 e9 83 00 00 00 8d 76 00 8b 44 24 18 89 f2 e8 7d 12 30 00<8b> 73 08 8b 7c 24 24 8b 07 8b 40 18 85 c0 89 44 24 08 0f 84 c5 >> EIP: [<c05235b3>] mem_cgroup_force_empty+0x123/0x4a0 SS:ESP 0068:f34e7e84 >> CR2: 00000000fffffffc > Code: 89 7c 24 20 8b 54 95 08 31 ff 89 44 24 14 81 c2 00 01 00 00 89 54 24 10 e9 83 00 00 00 8d 76 00 8b 44 24 18 89 f2 e8 7d 12 30 00<8b> 73 08 8b 7c 24 24 8b 07 8b 40 18 85 c0 89 44 24 08 0f 84 c5 > All code > ======== > 0: 89 7c 24 20 mov %edi,0x20(%esp) > 4: 8b 54 95 08 mov 0x8(%ebp,%edx,4),%edx > 8: 31 ff xor %edi,%edi > a: 89 44 24 14 mov %eax,0x14(%esp) > e: 81 c2 00 01 00 00 add $0x100,%edx > 14: 89 54 24 10 mov %edx,0x10(%esp) > 18: e9 83 00 00 00 jmp 0xa0 > 1d: 8d 76 00 lea 0x0(%esi),%esi > 20: 8b 44 24 18 mov 0x18(%esp),%eax > 24: 89 f2 mov %esi,%edx > 26: e8 7d 12 30 00 call 0x3012a8 > 2b:* 8b 73 08 mov 0x8(%ebx),%esi<-- trapping instruction > 2e: 8b 7c 24 24 mov 0x24(%esp),%edi > 32: 8b 07 mov (%edi),%eax > 34: 8b 40 18 mov 0x18(%eax),%eax > 37: 85 c0 test %eax,%eax > 39: 89 44 24 08 mov %eax,0x8(%esp) > 3d: 0f .byte 0xf > 3e: 84 c5 test %al,%ch > > Could you send your config file.

Then, mem_cgroup_pre_zone[] was initialized once. In this kind of case, I tend to check slab header of memory object f3446a00, or check whether f3446a00 is an alive slab object or not.

Oh dear. I'm having a look at the linux code now to try and understand the behaviour. In the meantime, what version of Xen was this on? If you're willing to try recompiling Xen with some small patches that disable the "cleverer" parts of the shadow pagetable code that might indicate something. (Of course, it might just change the timing to obscure a real linux bug too.) The only time I've seen a corruption like this, with a mapping transiently going to the wrong frame, it turned out to be caused by 32-bit pagetable-handling code writing a PAE PTE with a single 64-bit write (which is not atomic on x86-32), and the TLB happening to see the intermediate, half-written entry. I doubt that there's any bug like that in linux, though, or we'd surely have seen it before now.

More detailed info can be found at RHBZ#700565 The best way to be sure whether HAP is in use is to connect to the serial line, hit ^A^A^A to switch input to Xen, and hit 'q' to dump per-domain state. The printout for the guest domain should either say "paging assistance: shadow refcounts translate external" or "paging assistance: hap refcounts translate external". (If you don't have serial you can get the same info by running "xm debug-keys q" and then "xm dmesg" to read the output.) > >you're willing to try recompiling Xen with some small patches that > >disable the "cleverer" parts of the shadow pagetable code that might > >indicate something.

Actually, looking at the disassembly you posted, it looks more like it might be an emulator bug in Xen; if Xen finds itself emulating the IMUL instruction and either gets the logic wrong or does the memory access wrong, it could cause that failure. And one reason that Xen emulates instructions is if the memory operand is on a pagetable that's shadowed (which might be a page that was recently a pagetable). ISTR that even though the RHEL xen reports a 3.0.x version it has quite a lot of backports in it. Does it have this patch? http://hg.uk.xensource.com/xen-3.1-testing.hg/rev/e8fca4c42d05 Cheers, Tim. -- Tim Deegan <Tim.Deegan@citrix.com> Principal Software Engineer, Xen Platform Team Citrix Systems UK Ltd.

Based on a quick scrobble through the CentOS 5.6 SRPMs it looks like a 3.1.0 hypervisor with a bunch of extra patches, but not this one. This is very likely the cause of the crash in mem_cgroup_create(), and probably the corruptions too. That would explain why they didn't happen on a 4.0.x SLES11 Xen, but not really why the original patch in this thread made it go away.

Putting extra printk inside zone loop or flushing tlb before it also make problem go away. Or may be problem just becomes invisible and memory is corrupted at another place. PS: Well, never mind.

And yes, I agree that it is rather a workaround than real fix of race condition which shouldn't exist in the first place. But giving my very limited knowledge of cgroups and difficulty to reproduce the crash after adding/enabling additional debugging, that patch is what can fix the problem for now. And maybe more experienced guys will look at the code and fix it in the right way. Well at least I hope for that. ^ permalink raw reply [flat|nested] 30+ messages in thread
