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.

In particular, anyone who was having trouble with sched-domains and/or CPU
hotplug please test this.

It is supposed to fix all known issues, but some patches are fairly involved,
and not having been tested on problem hardware, there could be still some bugs.
Please let me know if anything goes bug.

Also, ia64 sched-domains setup is possibly still broken. If anyone boots this
on an Altix, please send over the full dmesg! Thanks.

This one is still needlessly messing around in procfs internals.

I can't build it on x86-64:

  LD      init/built-in.o
  LD      .tmp_vmlinux1
fs/built-in.o(.text+0xd1893): In function `mask_ok_common':

make: *** [.tmp_vmlinux1] Error 1

The .config is attached.

It's reiser4, apparently:

  CC      fs/reiser4/plugin/security/perm.o

fs/reiser4/plugin/security/perm.c:16: warning: implicit declaration of

just don't set ->permission for reiser4 and kill the whole perm_plugin
bullshit.  This fixes the issue by removing a few hundred lines of code which
is always a good idea.

OK, starfire broke and qlogicisp. Plus some NUMA stuff in mm/mempolicy.c
Full error log below. Config is (on ia32):

ftp://ftp.kernel.org/pub/linux/kernel/people/mbligh/config/config.numaq

The NUMA one is either cpusets-big-numa-cpu-and-memory-placement.patch
or create-nodemask_t.patch by the looks of it. The only thing touching
starfire is bk-netdev.patch, but as I get very similar errors from qlogicisp
maybe someone's been futzing with readw/writew ?

The numa one, with the following errors:

  mm/mempolicy.c: In function `get_zonemask':
  mm/mempolicy.c:419: error: `maxnode' undeclared (first use in this function)

is due to fix-abi-in-set_mempolicy.patch.

Hello Andrew,

Please replace patch next_thread-bug-fixes.patch in -mm5 tree with the 
last diff-next_thread I sent to you.

And it looks like thread loop in do_task_stat() doesn't require siglock 
lock, so you can add the patch attached to reduce lock area.

Kirill

That worked - thanks.

The others seem only to be warnings, and are allegedly no worse than before,
so maybe it'll work now ;-)

It's not working for me - on a small ia64 SN2, it crashes during boot. 
Somewhere between the 32 and 42 patch of Andrews broken out set of 436
patches ... I'm still in the binary search loop.

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.  Here's the 
dmesg from a 2p, 1 node box, I'll send out a more complete one later (unless 
Paul beat me to it, I'm still only part way through my lkml mailbox).

Thanks,
Jesse

On an Altix with the default config (smp+preempt, see

Shortly after the backtrace I've already posted, I got one panic that looked 
like this:

Kernel panic - not syncing: Aiee, killing interrupt handler!
Rebooting in 5 seconds..

The ip above is in sshd presumably, and the warning message corresponds to 
somewhere in tcp_recvmsg:

a0000001006434e0 T tcp_recvmsg
a000000100644760 t tcp_close_state

Is this a known problem?

Thanks,
Jesse

Nope, VLAN isn't set:

Hmmm, then that's a really strange backtrace.  What networking
driver are you using?

I got the same messages, on another Altix sn2_defconfig, after I had:

 2) played around a bit, then
 3) issued a 'reboot' command.

Then bamo - lots of scheduling while atomic! complaints.  Though the
shutdown did succeed, and shut the complaints off.

tg3.  I saw one trace that included do_poll (iirc) and another last week that 
had sys_select in it.  I'll try to gather some more info.

What you're seeing might be due to the bug fixed by this patch:

Ok, I guess that would explain why I haven't seen this in 2.6.9-rc2.  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.

Thanks,
Jesse

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.

[-- Attachment #1: Type: TEXT/PLAIN, Size: 5658 bytes --]

I'm experiencing TCP related oopses with this kernel (not seen in -mm4), 
.config file attached.

Here are two backtraces, the first happened a few seconds after logging 
in via ssh, the second happened soon after boot (using selinux=0, just to 
make sure).

Oops #1:

I think I fixed this one yesterday.  Callers of tcp_fragment()
in tcp_output.c were not accounting packets correctly.  I
believe this is what will fix it, and this is in Linus's
tree already.

I guess you have an e1000 in this box? :)

The following 3 updates address various issues expressed to me in
unrelated threads or messages, and while none of them are particularly
pressing each does resolve a concern I've deemed valid.

I was informed that the vendor component of the copyright can't be
clobbered without more care, so this patch retains the older vendor,
updating it only to reflect the appropriate time period.

/proc/ breaks when PID_MAX_LIMIT is elevated on 32-bit, so this patch
lowers it there. 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.
Compiletested on x86-64.

Not all binfmts page align ->end_code and ->start_code, so the task_mmu

This patch is also in -mm5 (linus.patch), and the oopses go away when I

That should be tcp_inc_pcount_explicit.

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.

Better fix is to transpose the factors in the subtraction.
That's what I was trying to do here.

William, any reason not to fully per-cpu the profile buffer
and then only traverse the array when the user attempts to
capture the counters?

Then we can undo the atomics altogether, as well as the cacheline
traffic, for the extremely common case.

Are there space concerns?

That's a bit of a problem, isn't it?  As we can accumulate an arbitrarily
large number of hits within the hash table is it not possible that the
/proc/profile results could be grossly inaccurate?

If you had two front-ends per cpu to the profiling buffer then the CPU
which is running the /proc/profile read could tell all the other CPUs to
flip to their alternate buffer and can then perform accumulation at its
leisure.

How does oprofile get around this?  I guess in most modes the CPUs are not
synchronised.

One wonders how long we should keep flogging the /prof/profile profiling
code.  What systems are seeing this livelock?

This is superior to no flushing; I'll implement that and send out an
incremental update (or if preferred, an update of this patch).

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 personally intend to do no further adjustments.

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. I suspect iterating over pages of the profile buffer and
storing intermediate results for a page full of profile buffer hits
in a buffer page may suffice though I've not tried it.

I bet that, like we found out about page tables on 64-bit, these
profile buffers are sparsely populated with hits.  So perhaps a
per-cpu bitmap that indicates regions that might have any hits
at all, allowing large amounts of skipping and thus amortizing the
scan cost.

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).

1. next_thread-bug-fixes.patch has nothing to do with Ingo's patch.
next_thread-bug-fixes.patch is cosmetic and a bit unfull (it should 
better check that the process is still hashed, which I added in my patch).
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.

My patch was a bit more self explaining as we discussed with Ingo.
But due to being already fixed, I don't think you have to bother with it.

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.

It's for exclusion from the timer interrupt. It looks like ia32 enters
the calls with interrupts disabled, so it's probably safe to assume
it's called with disabled interrupts for all architectures (or what
architectures don't are broken by other callers elsewhere). I'll send
out an update with the explicit interrupt disablement removed.

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.

So, my preferred fix is the following, with which I'll send out an
updated patch if everyone agrees:

The comments and all other issues raised in your reply have been
addressed in the following updated patch, in which I also shrank the
hashtable entries' fields to u32 for 64-bit machines, on which the full
precision of an unsigned long is unnecessary, added some commentary to
the beginning of the file describing its contents and the recent major
work done on it, and simplified the secondary hash function. I also
presume silence to be assent regarding the hotplug (not preempt) fix.

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

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 also took the liberty of adding some commentary to the comments at
the beginning of the file reflecting the major work done on profile.c
in recent months and describing what the file implements..

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.

include/linux/key.h defines struct key that conflicts with reiserfs'
struct key. As a temporary fix turn off CONFIG_KEYS (or
CONFIG_REISERFS_FS :)).

Correct solution is to put both structs into proper namespaces by
prefixing them.

struct key was pretty dumb of both of you, but reiserfs was dumb first.

isn't it *much* simpler and much more efficient to just have a per-cpu
idle function? I seriously doubt you'll get simultaneous collisions on
anything but the 'halt' instruction in the idle function.

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?

Then there's the related problem of what do do about the naming of 
key_alloc(), key.h etc.

What about 'akey', where a is for authentication or access.

How about struct key_cookie? Though I think I like struct key_token better. I

Sampling the profile buffer at regular intervals shows far less than
256 distinct functions hit in 1s intervals even with all cpus busy. As
for whether that would be sufficient, that will have to be answered by
those who reported the bug. I suppose to test whether things besides
idling do cause this problem, one would boot with a restricted
prof_cpu_mask, load all cpus on the machine, set the prof_cpu_mask to
unrestricted, and see if it livelocks before the load terminates.

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.

Before dedicidng I'd suggest to have a look and see how the below patch
compares to your approch in performance terms.

Right, we want to avoid that heavy contention.

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.

Thanks,
Jesse

per-cpu certainly sounds simple enough conceptually, so if you can
notice any slowdown even with idle loop ruled out, per-cpu is sure
better.

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. So an
intermediate solution for this problem still sound worthwhile for the
normal smp case.

Could you clarify whether you deem the per-cpu hashtable -based
amortization acceptable or whether this refers to per-cpu profile
buffers? I devised the hashtables to address space footprint concerns,
so I'm in a pickle if both have pending objections.

Thanks.

Ok, is *this* the sort of thing you'd expect this patch to fix?  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

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.

Okay, here's an attempt to hotplug-ize it. I have no clue whether this
actually works, compiles, or follows whatever rules there are about
dynamically allocated data referenced by per_cpu areas.

As pointed out by John Hawkes, I forgot to flush the pending hits at

Hmm, I can only see this happening if rq->flags has its direction bit
changed between the allocation time and the time of freeing. I'll look
over scsi and see if I can find any traces of that, don't see any

It appears to have lasted enough hours to call it an improvement. I'll
leave it running for a while longer just in case.
