The following assignment in smp_call_function_many() may cause unexpected
behavior, when !CPUMASK_OFFSTACK.
data->cpumask = allbutself;
Because it copys pointer of stack and the value will be modified after
exit from smp_call_function_many().
The type of cpumask field of call_function_data structure should be
cpumask_var_t and an operation to assign is needed.

Good catch!

This makes the lifetime rules dependent on the config option, which is
complicated.
Your insight into this issue is appreciated: this code is not simple!
How's this version instead? It puts the cpumask at the end of the kmalloc,
and falls back to smp_call_function_single instead of doing obscure
quiescing stuff.
(Compiles, untested).
Thanks!
Rusty.

Ingo, because of these concerns I recommend you revert
d4de5ac3b5e70928c86e3e5ac311f16cbf2e9ab3 (cpumask: smp_call_function_many())
for now, and apply this less contentious version.
Subject: cpumask: smp_call_function_many()
From: Rusty Russell <rusty@rustcorp.com.au>
Transition from cpumask_t-taking smp_call_function_mask() to a new
smp_call_function_many() which takes a struct cpumask * instead.
(Naming is inspired by smp_call_function_single).
Unfortunately, converting the function implementation properly is
non-trivial, but what we care about is the API, so this simply wraps
it.
Note that the new one returns void: the old one couldn't fail either
unless there was a logic bug.
The old smp_call_function_mask() isn't marked __deprecated, because
sparc64 builds with -Werr in arch/sparc (thanks Stephen).

Indeed, thanks.
Here is updated patch, also tested, and I forced the kmalloc failure path
to test that too...
From: Rusty Russell <rusty@rustcorp.com.au>
cpumask: smp_call_function_many()
Actually change smp_call_function_mask() to smp_call_function_many().
S390 has its own version, so we do trivial conversion on that too.
We have to do some dancing to figure out if 0 or 1 other cpus are in
the mask supplied and the online mask without allocating a tmp
cpumask. It's still fairly cheap.
We allocate the cpumask at the end of the call_function_data
structure: if allocation fails we fallback to smp_call_function_single
rather than using the baroque quiescing code.
(Thanks to Hiroshi Shimamoto for spotting several bugs in previous versions!)

ok - applied it to tip/cpus4096-v2, thanks Rusty!
If there's any chance for this in v2.6.28 then only if we disable the
dynamic API branch altogether [CONFIG_MAXCPUS] and keep that for
v2.6.29. This means we'd bring in the API changes which should have
trivial impact only - and none of the riskier changes.
Hm?
Andrew, have we missed the boat on this?

in any case, i've started testing tip/cpus4096-v2 again on x86 - the
problem with d4de5a above was the only outstanding known issue, right?

Subject: [PATCH] cpumask: fixlets
[ from Mike ]
Here are the only changes I could find from Rusty's last patches that
apply to tip/cpus4096-v2.
* Fix NR_CPUS reference in arch/powerpc/platforms/cell/spu_base.c
* modify arch/x86/Kconfig so CONFIG_NR_CPUS is always defined. Also it
does not prompt if MAXSMP is set.
* change include/linux/threads.h so CONFIG_NR_CPUS is defined for those
arch's that do not define it.

the sched_init() slab corruption bug is still there, i just triggered it
on two separate test-systems:
[ 0.510620] CPU1 attaching sched-domain:
[ 0.512007] domain 0: span 0-1 level CPU
[ 0.517730] groups: 1 0
[ 0.520528] =============================================================================
[ 0.524002] BUG kmalloc-8: Wrong object count. Counter is 11 but counted were 50
[ 0.524002] -----------------------------------------------------------------------------
[ 0.524002]
i've pushed out that specific tree: tip/tmp.cpus4096-v2.broken, which
you should be able to reproduce via:
git remote update
git checkout -b tmp.test tip/tmp.cpus4096-v2.broken
config attached. This config should just run through a 'make oldconfig'
fine and if the bzImage is built, it should produce the slab corruption
messages on any typical 64-bit PC. I've attached the boot log below as
well. (You can see the gcc version i used in the bootup log as well.)
I'll disable MAXSMP in these testruns - just to establish the stability
without any of the dynamic-cpumask_t stuff.

Agreed. The important thing is to get the new APIs in place so we can feed
the updates to various maintainers (esp. arch maintainers).
Thanks,
Rusty.

Hm,
I think kmalloc-8 is too small.
In this case, struct cpumask is defined;
struct cpumask {
DECLARE_BITMAP(bits, NR_CPUS);
};
So, storing cpumask such as cpu_core_map, cpu_sibling_map and sd->span etc.
requires NR_CPUS bits. In Ingo's config, it needs 4096 bits.
At alloc_cpumask_var uses cpumask_size() for kmalloc(),
bool alloc_cpumask_var(cpumask_var_t *mask, gfp_t flags)
{
if (likely(slab_is_available()))
*mask = kmalloc(cpumask_size(), flags);
cpumask_size() looks nr_cpumask_bits and it defined as follows;
#define nr_cpumask_bits nr_cpu_ids
it's CONFIG_NR_CPUS > BITS_PER_LONG case.
And now nr_cpu_ids is 2 on this boot log.
...
> [ 0.000000] PERCPU: Allocating 1900544 bytes of per cpu data
> [ 0.000000] NR_CPUS:4096 nr_cpumask_bits:2 nr_cpu_ids:2 nr_node_ids:1
So, kmalloc(8, flags) for cpumask_var_t at alloc_cpumask_var().
But the content is treated as cpumask_t, it causes slab corruption
with overwritten when the mask data is copied.
For example, cpu_to_core_group()
static int
cpu_to_core_group(int cpu, const cpumask_t *cpu_map, struct sched_group **sg,
cpumask_t *mask)
{
int group;
*mask = per_cpu(cpu_sibling_map, cpu);
this copies 0x200 bytes (= 4096 bits), compiled my environment as follows;
ffffffff80251c56 <cpu_to_core_group>:
cpu_to_core_group():
ffffffff80251c56: 55 push %rbp
ffffffff80251c57: 48 63 ff movslq %edi,%rdi
ffffffff80251c5a: 48 89 e5 mov %rsp,%rbp
ffffffff80251c5d: 41 55 push %r13
ffffffff80251c5f: 49 89 d5 mov %rdx,%r13
ffffffff80251c62: ba 00 02 00 00 mov $0x200,%edx
ffffffff80251c67: 41 54 push %r12
ffffffff80251c69: 49 89 f4 mov %rsi,%r12
ffffffff80251c6c: 48 c7 c6 00 c1 c8 81 mov $0xffffffff81c8c100,%rsi
ffffffff80251c73: 53 push %rbx
ffffffff80251c74: 48 89 cb mov %rcx,%rbx
ffffffff80251c77: 48 83 ec 08 sub $0x8,%rsp
ffffffff80251c7b: 48 8b 05 3e d0 98 01 mov 0x198d03e(%rip),%rax # ffffffff81bdecc0 <_cpu_pda>
ffffffff80251c82: 48 8b 04 f8 mov (%rax,%rdi,8),%rax
ffffffff80251c86: 48 89 cf mov %rcx,%rdi
ffffffff80251c89: 48 03 70 08 add 0x8(%rax),%rsi
ffffffff80251c8d: e8 de 29 25 00 callq ffffffff804a4670 <__memcpy>
the 3rd parameter of __memcpy is rdx = 0x200.
So, I guess, we need
kmalloc(BITS_TO_LONGS(NR_CPUS), flags)
at alloc_cpumask_var().
Or change cpumask handling in sched.c etc?
I've no idea for this more, now.
thanks,
Hiroshi Shimamoto

Yes. This is another one.
Ingo, please fold.
Subject: Fix slab corruption when using CONFIG_CPUMASK_OFFSTACK
Found by Hiroshi Shimamoto; using assignment on a cpumask_t causes slab
corruption, as we do not allocate sizeof(struct cpumask).
It looks like we will have to stick with allocating all NR_CPUS bits until the
end of the patchset (in the future) where we have eliminated all the
cpumask_t assignments.
(Note: this ban will be enforced by compiler when we get rid of the 'struct
cpumask' definition, which is what we're slowly working towards).

Hi Rusty,
I'd like to know which tree this patch is against for.
