  To: Linux Kernel Mailing List

Ok, another week, another -rc.

And as I suspected, the reason -rc5 was so small was that a lot of
people were still getting ready after the Kernel Summit. So -rc6 is a
bit larger, since people were playing catch-up. That said, it's not
*huge* either, and it's not like it looks scary, but it's definitely
not tiny.

Fairly normal statistics: two thirds drivers, with the remaining third
being a mix of architecture updates, filesystems (gfs2 and nfs) and
random core stuff (scheduler, workqueue, stuff like that).

Please do test things out, I'd really like to be able to do the final
3.6 soonish..

                  Linus

Linus,

Just a heads up in case you are about to tag v3.6.

v3.6-rc6 still has a regression with edac_mc_alloc()/edac_mc_free()
introduced in commit de3910eb79ac8c0f29a11224661c0ebaaf813039.
edac_mc_free() assumes that struct mem_ctl_info is registered in
sysfs but there are error paths where this is not always the case.

I posted patches [1,2,3] that resolve the issue for me. Shaohui Xie
also hit the issue and posted a slightly different patch [4]. The
patches are currently waiting for Mauro, who I understand is
catching up since returning from San Diego, to check them out.

That first patch needs a sign-off from you, since you are passing on
somebody elses patch.

Looking at that patch, the patch seems to be a memory leak (?) leaking
the "channels" allocation, along with fixing an odd and incorrect
kfree (and access) of mci->csrows[i]. If that is correct, please write
a proper changelog. The current changelog for that thing is totally
pointless, and doesn't actually explain what the patch *does*.

I'd also like some ack's from people, and I'd love to know which
commit introduced the problem(s). If this problem is new to 3.6, I
want to know what caused it, and if it is *not* new, then the thing
needs to be marked for stable. Please?

Finally, if I'm supposed to apply patches, I really *really* want to
see the patches sent to me explicitly, instead of having people post
pointers to them on the web. I don't apply random stuff on the web, I
want the "please take this patch" to be a case of people *explicitly*
sending it to me with the proper sign-offs in place etc.

IOW, the "hey, you should apply that random patch that wasn't even
sent to you" approach is not something I accept.

Yes.

Right.

Sorry I'll send the fix with more complete changelog in a standalone
patch for review.

It's a new bug to 3.6.

   431                  kfree(mci->csrows);
   432          }

and that code block seem to mess things up in several ways (double free, memory
leak, out-of-bound reads etc.):

L422: The iterator "chn" and bound "tot_channels" are totally wrong. Should be
      "row" and "tot_csrows" respectively. Which means either memory leak, or
      out-of-bound reads (which if does not trigger an immediate page fault
      error, will further lead to kfree() on random addresses).

L425: The inner loop is reusing the same iterator "chn" as the outer loop,
      which could lead to premature end of the outer loop, and hence memory leak.

L429: The array index 'i' in mci->csrows[i] is a temporary value used in
      previous loops, and won't change at all in the current loop. Which
      means either out-of-bound read and possibly kfree(random number), or the
      same mci->csrows[i] get freed once and again, and possibly double free
      for the kfree(csr) in L427.

L426/L427: a kfree(csr->channels) is needed in between to avoid leaking the memory.

The buggy code was introduced by commit de3910eb ("edac: change the mem
allocation scheme to make Documentation/kobject.txt happy") in the 3.6-rc1
merge window. Fix it by freeing up resources in this order: 

  free csrows[i]->channels[j]
  free csrows[i]->channels
  free csrows[i]
  free csrows

Fix potential NULL pointer dereference in edac_unregister_sysfs() on
system boot introduced in 3.6-rc1. This patch is dependent on
Fengguang's "edac_mc: fix messy kfree calls in the error path".

Since commit 7a623c039 ("edac: rewrite the sysfs code to use struct
device") edac_mc_alloc() no longer initializes embedded kobjects in
struct mem_ctl_info. Therefore edac_mc_free() can no longer simply
decrement a kobject reference count to free the allocated memory
unless the memory controller driver module had also called
edac_mc_add_mc().

Now edac_mc_free() will check if the newly embedded struct device
has been registered with sysfs before using either the standard
device release functions or freeing the data structures itself with
logic pulled out of the error path of edac_mc_alloc().

The BUG this patch resolves for me:

Hi Linus, I did not bother to resend the third patch [1] since it's
not really *necessary* to boot my system. Fengguang's and this is
sufficient.

This was caused by the edac core rewrite I made, merged for 3.6, that
replaced the usage of raw kobj in order to use, instead, struct device.

I tested the patches on several machines and they're OK. It took
me some time to test them, as I got flooded with ~400 patches for
review while I was out for KS/2012... It is taking some time for me to
dig into each of them, especially since I hit into some internal dead
lines.

The good news is that we are equipping several machines at Red Hat labs
with different memory configurations, with is allowing us to do a
comprehensive testset on the EDAC x86 drivers. We've got already 
some longstanding bugs there, as well as a few recent regressions.

So, in addition to the bugs noticed by Shaun and Fengguang, 
I also got bug fixes for 3 EDAC drivers (sb_edac, i3200 and i5000).

I just updated the patches today on my git tree (so, they should be
popping up tomorrow at -next).

So, I will send you tomorrow a pull request with all fixes I'm aware 
of for edac, after the -next merging.

If you prefer otherwise to merge them today, you can get those patches
with my SOB at:

  git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-edac.git master


Thanks!
Mauro

Works fine on my (localized) desktop, except with bootparameter  
"threadirqs" which has not been working since it was introduced.
Jitterlevels are very low now, regular os-jitter is typically below 1 ms.  
(with a low jitter config) Which means audioapps run 1 ms latency, without  
rt-threads, and opengl is very smooth.
I would really love to get that down to 250uS though, after which I don`t  
care.

I also did the low-jitter config on the latest ubuntu-kernel, and wrote a  
little bit about it here.
