To: linux-kernel
Due to master.kernel.org being on the blink, 2.6.9-rc1-mm5 Is currently at
http://www.zip.com.au/~akpm/linux/patches/2.6.9-rc1-mm5/
and will later appear at
ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.9-rc1/2.6.9-rc1-mm5/
Please check kernel.org before using zip.com.au.
- Added the `bk-scsi-target' tree to the -mm lineup. It is managed by James
Bottomley
- Some enhancements to the ext3 block reservation code here. Please cc
sct@redhat.com on oops reports ;)
- There's a patch here which will cause warnings if a PCI device driver is
removed without having called pci_disable_device(). Please try to cc the
appropriate mailing list or maintainer when reporting any instances.

Didn't you get my last mail about this? Looks like the lack of !defined(SD_NODE_INIT) in sched.h made its way to Andrew.

So I ask you to replace it with diff-next_thread (I resend it once again), which fixes original kernel and should replace the above patch in your tree. The comments for this patch ~~~~~~~~~~~~~~~~~~~~~~~~~~~ This patch changes obscure BUG() checks in next_thread() with pid checks meaning exactly the same (It simply checks if the task is still hashed). Also original check was incorrect since it required ANY of the locks (siglock or tasklist_lock) while siglock is not required at all and tasklist_lock is ALWAYS required. Signed-Off-By: Kirill Korotaev <dev@sw.ru> 2. The BUG() which is resolved in Ingo's patch is fixed in -mm5 tree with show-aggregate-per-process-counters-in-proc-pid-stat-2.patch So you needn't to apply Ingo's patch. > --- linux/fs/proc/array.c.orig > +++ linux/fs/proc/array.c > @@ -356,7 +356,7 @@ static int do_task_stat(struct task_stru > stime = task->signal->stime; > } > } > - if (whole) { > + if (whole && task->sighand) { > > Is there some reason why your patch is better?

Well, I argue that it wasn't that dumb - in this case it's meant to be a generic mechanism usable by everything in the kernel or userspace that needs authentication, authorisation, or crypto tokens. I use EXT3 rather than ReiserFS, so it didn't become an issue. > David, what do you want it renamed to? key_struct? token? key_token? Possibly ticket or principal, though they make it sound like it's specifically for Kerberos, so perhaps not. What I need is a thesaurus. JamesM: any good suggestion as to a name?

I was getting my backtraces confused too--I've only seen this one for this bug. I'll keep an eye out and report anything I see with the latest bk tree.

The patch isn't in the tree yet, you would see the problem in 2.6.9-rc2 Please try to get a clean backtrace with a current tree plus the patch I posted, and I'll scratch my head some more. :-) ^ permalink raw reply [flat|nested] 96+ messages in thread

I've seen it on a couple of different machines now (one 32p and one 8p), but I haven't seen it since applying the above to the BK tree as of this morning. Either way, I'll keep pounding on different machines using the BK tree + your patch to see what problems I run into. Thanks, Jesse bad: scheduling while atomic!

Compiletested on x86-64. The pid_max sysctl doesn't enforce PID_MAX_LIMIT or sane lower bounds. RESERVED_PIDS + 1 is the minimum pid_max that won't break alloc_pidmap(), and PID_MAX_LIMIT may not be aligned to 8*PAGE_SIZE boundaries for unusual values of PAGE_SIZE, so this also rounds up PID_MAX_LIMIT to it.

Please try to cc the > appropriate mailing list or maintainer when reporting any instances. I've been informed that /proc/profile livelocks some systems in the timer interrupt, usually at boot. The following patch attempts to amortize the atomic operations done on the profile buffer to address this stability concern. This patch has nothing to do with performance; kernels using periodic timer interrupts are under realtime constraints to complete whatever work they perform within timer interrupts before the next timer interrupt arrives lest they livelock, performing no work whatsoever apart from servicing timer interrupts. The latency of the cacheline bounce for prof_buffer contributes to the time spent in the timer interrupt, hence it must be amortized when remote access latencies or deviations from fair exclusive cacheline acquisition may cause cacheline bounces to take longer than the interval between timer ticks. What this patch does is to create a per-cpu open-addressed hashtable indexed by profile buffer slot holding values representing the number of pending profile buffer hits. When this hashtable overflows, one iterates over the hashtable accounting each of the pairs of profile buffer slots and hit counts to the global profile buffer. Zero is a legitimate profile buffer slot, so zero hit counts represent unused hashtable entries. The hashtable is furthermore protected from reentry into the timer interrupt by interrupt disablement. read_proc_profile() does not flush the per-cpu hashtables because flushing may cause timeslice overrun on the systems where prof_buffer cacheline bounces are so problematic as to livelock the timer interrupt. This is expected to be a much stronger amortization than merely reducing the frequency of profile buffer access by a factor of the size of the hashtable because numerous hits may be held for each of its entries. This reduces what was before the patch a number of atomic increments equal to what after the patch becomes the sum of the hits held for each entry in the hashtable, to a number of atomic_add()'s equal to the number of entries in the per_cpu hashtable. This is nondeterministic, but as the profile hits tend to be concentrated in a very small number of profile buffer slots during any given timing interval, is likely to represent a very large number of atomic increments. This amortization of atomic increments does not depend on the hash function, only the (lack of) scattering of profile buffer hits. I would be much obliged if the reporters of this issue could verify whether this resolves their livelock. Untested, as I was hoping the bugreporters could do that bit for me.

This was my original approach (modulo eliminating the global buffer and the atomic operations), but space concerns stymied it, as the profile buffer can be several megabytes large. It would likely perform better in general if admissible, for whatever value performance is considered to have. There is also an unusual facet to this; the TLB overhead of a loop like: for (i = 0; i < prof_len; ++i) { for_each_online_cpu(cpu) global_buf[i] += per_cpu(cpu_prof_buffer, cpu)[i]; } is very large and caused "effective nontermination", otherwise known as "exhausting the user's patience", on SGI's systems after about half an hour. So some TLB overhead amortization is necessary for this to be feasible.

Well, that would speed it up, but the catastrophe was avoided in the older patches by just processing all the hits for one cpu at a time, and the buffering methods above for your suggested accounting structures likely work well enough the overhead of processing unused portions of the bitmap can be ignored. I don't really want to go about addressing performance issues besides effective or actual nontermination for this code, and would rather leave highly efficient methods to oprofile (in fact, some others believe that even bugfixes for such issues should be ignored for kernel/profile.c, contrary to my notion that it shouldn't crash systems regardless of their size). -- wli ^ permalink raw reply [flat|nested] 96+ messages in thread

The original bits were merely a consolidation extracted from a since- dropped feature patch and an unrelated feature patch from mingo and arjanv; this is an unrelated fix for SGI's stability issue on larger Altixen.

I've been informed that /proc/profile livelocks some systems in the timer interrupt, usually at boot. The following patch attempts to amortize the atomic operations done on the profile buffer to address this stability concern. This patch has nothing to do with performance; kernels using periodic timer interrupts are under realtime constraints to complete whatever work they perform within timer interrupts before the next timer interrupt arrives lest they livelock, performing no work whatsoever apart from servicing timer interrupts. The latency of the cacheline bounce for prof_buffer contributes to the time spent in the timer interrupt, hence it must be amortized when remote access latencies or deviations from fair exclusive cacheline acquisition may cause cacheline bounces to take longer than the interval between timer ticks. What this patch does is to create a per-cpu open-addressed hashtable indexed by profile buffer slot holding values representing the number of pending profile buffer hits. When this hashtable overflows, one iterates over the hashtable accounting each of the pairs of profile buffer slots and hit counts to the global profile buffer. Zero is a legitimate profile buffer slot, so zero hit counts represent unused hashtable entries. The hashtable is furthermore protected from reentry into the timer interrupt by interrupt disablement. In order to "flush" the pending profile hits for read_profile(), this patch actually creates a pair of per-cpu profile buffer, and at the time of read_profile() IPI's all cpus to get them to flip between their pairs of profile buffers, doing all the work to flush the profile hits from the older per-cpu buffers in the context of the caller of read_profile(), with exclusion provided by a semaphore ensuring that only one caller of profile_flip_buffers() may execute at a time and interrupt disablement to prevent buffer flip IPI's from altering the hashtables or flip state while an update is in progress. The flip state is per-cpu so that remote cpus need only disable interrupts locally for synchronization, which is both simple and busywait-free for remote cpus, and the flip states all change in tandem with the cpu requesting the update waiting for the completion of smp_call_function() for notification that all cpus have finished flipping their buffers. The IPI handler merely toggles the flip state (which is an array index) between 0 and 1. This is expected to be a much stronger amortization than merely reducing the frequency of profile buffer access by a factor of the size of the hashtable because numerous hits may be held for each of its entries. This reduces what was before the patch a number of atomic increments equal to what after the patch becomes the sum of the hits held for each entry in the hashtable, to a number of atomic_add()'s equal to the number of entries in the per_cpu hashtable. This is nondeterministic, but as the profile hits tend to be concentrated in a very small number of profile buffer slots during any given timing interval, is likely to represent a very large number of atomic increments. This amortization of atomic increments does not depend on the hash function, only the (lack of) scattering of profile buffer hits. I would be much obliged if the reporters of this issue could verify whether this resolves their livelock. Untested, as I was hoping the bugreporters could do that bit for me.

Yes. It's irrelevant which cpu's cpu_profile_flip is sampled. But it's not cpu hotplug -safe, as the cpu may be offlined and the per-cpu storage freed in the duration between calling smp_processor_id() and dereferencing the offset from the start of the per-cpu area. Disabling preemption while it's being sampled (no longer than that is necessary) would repair it for cpu hotplug, as it would then have a valid cpu (the one on which it's executing) while the flip state is being sampled (it can't change because we own the semaphore, and won't vary by cpu unless the on_each_cpu() is in flight, but we have to have a valid cpu number to sample it). The cpucontrol semaphore would be excessively heavyweight and we'd either have to conditionally compile out the native semaphore for the cpu hotplug case or otherwise acquire two semaphores in succession. This raises an interesting question of how on earth for_each_online_cpu() is handled by cpu hotplug, but I don't feel responsible for answering it.

Sampling the profile buffer at regular intervals shows far less than 256 distinct functions hit in 1s intervals even with all cpus busy.

It probably worth to measure it. The real bottleneck happens when all cpus tries to get an exclusive lock on the same cacheline at the *same* time. 1 second is a pretty long time, if there's no contention of the cacheline, things are normally ok. this is basically the same issue we had with RCU since all timers fired at the same wall clock time, and all of them tried to change bits in the same cacheline at the same time, that is a workload that collapse a 512-way machine ;). The profile timer is no different. Simply removing the idle time accounting would fix it, however this cripple down functionality a little bit, but it'll be a very good way to test if my theory is correct, or if you truly need some per-cpu logic in the profiler. You could also fake it, have a per-cpu counter only for the current->pid case, and then once somebody reads /proc/profile, you flush the total per-cpu count to the counter in the buffer that corresponds to the EIP of the idle func.

It looks like the 512p we have here is pretty heavily reserved this week, so I'm not sure if I'll be able to test this (someone else might, John?). I think the balance we're looking for is between simplicity and non-brokenness. Builtin profiling is *supposed* to be simple and dumb, and were it not for the readprofile times, I'd say per-cpu would be the way to go just because it retains the simplicity of the current approach while allowing it to work on large machines (as well as limiting the performance impact of builtin profiling in general). wli's approach seems like a reasonable tradeoff though, assuming what you suggest doesn't work.

This bouncing is likely to hurt smaller SMP too (but once the cpu is idle normally it's not a too bad thing since it only hurted reschedule latency, since we remain stuck in the timer irq for a bit longer than we should), but duplicating the ram of the array there doesn't look as nice as it would be on the altix, not all SMP have tons of ram.

Could you clarify whether you deem the per-cpu hashtable -based amortization acceptable or whether this refers to per-cpu profile buffers?

Goddamn fscking short-format VHPT crap. Rusty, how the hell do I hotplug-ize this? -- wli Atop the prior per-cpu hashtable patch. It turns out that ia64 has limitations on the sizes of per-cpu areas to the size of an area covered by a single TLB entry, and worse yet, as short format VHPT is being used, this TLB entry is limited to the PAGE_SIZE of the region used for kernel data. In order to address this, the following patch dynamically allocates the per-cpu hashtables at boot-time. It probably needs adjustments for cpu hotplug.
