Linux 2.6.0

Linux 2.6.0

[Linus Torvalds]

				"The beaver is out of detox"
						- Anon

This should not be a big surprise to anybody on the list any more, since
we've been building up to it for a long time now, and for the last few
weeks I haven't accepted any patches except for what amounts to fairly
obvious one-liners.

Anyway, 2.6.0 is out there now, and the patch from -test11 is a swelte 
11kB in size. It's not the totally empty patch I was hoping for, but 
judging by the bugs I worked on personally, things are looking pretty 
good. 

To give you an example, one of the nastier bugs that we chased for the 
last five weeks was a bug that could only be reproduced reliably on a 
16- or 32-way system, and only when the system had flaky disks. Putting in 
known-good disks made the problem disappear. Similarly, compiling the 
kernel with another compiler made the problem disappear.

It turned out to be a really subtle bug wrt SMP ordering and stack
allocation, and lots of thanks to Ram Pai for gathering all the
information that eventually led to it being fixed. The fix was a one-liner
and a big comment - but my point is that the quality of bugs has been
pretty high lately, and we feel that we're in pretty good shape.

Andrew has written up some caveats and pointers to information about 2.4.x
vs 2.6.x changes, and I'll let him post that. Some known issues were not
considered to be release-critical and a number of them have pending fixes
in the -mm queue. Generally they just didn't have the kind of verification
yet where I was willing to take them in order to make sure a fair 2.6.0
release.

NOTE! I'll continue to keep track of the 2.6 BK tree until we're closer to
the time when we literally split it for 2.7.x, because both Andrew and I
are pretty comfortable with our respective toolchains. But Andrew is the
stable tree maintainer, so everything should be approved by him at this
point. Think of the -mm tree as the staging area, and mine as a release
tree. We'll work together, but Andrew is boss.

(BK merging will have to go through some approval format, we'll see how
that works out exactly).

Should we be expecting a 2.6.0-mm1 then?

It's actually rather short because I started late.  See below.

There are also the "must-fix" and "should-fix" lists of items which we have
identified as still on the 2.6 todo list.  These are at

ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/must-fix/must-fix-7.txt and
ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/must-fix/should-fix-7.txt




- The 2.6.0 kernel has undergone several weeks of stabilization and we
  expect it to run well on server-class machines.

  Desktops and laptops may have more trouble at this time because of the
  much wider range of hardware and because of as-yet unimplemented fixes for
  the hardware and BIOS bugs from which these machines tend to suffer.

  During the 2.6.0 stabilization period a significant number of less
  serious fixes have accumulated in various auxiliary kernel trees and these
  shall be merged into the 2.6 stream after the 2.6.0 release.  Many of these
  fixes appear in Andrew Morton's "-mm" tree, at

	ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/

- Please report any problems to the appropriate mailing list.  If you do
  not know which list to use, send the report to linux-kernel@vger.kernel.org
  and it should reach the right person.  Some active subsystem mailing lists
  are:

	linux1394-devel@lists.sourceforge.net
	linux-xfs@oss.sgi.com
	linux-acpi@intel.com
	linux-scsi@vger.kernel.org
	ext2-devel@lists.sourceforge.net
	linux-usb-users@lists.sourceforge.net

  Alternatively, kernel bug reports may be entered into the kernel bug
  tracking system at http://bugme.osdl.org/

- There are significant changes in the module subsystem, the LVM (Device
  Mapper) and RAID subsystems.  Details about these and many other kernel
  changes are presented in David Jones's kernel upgrade document at

	http://www.linux.org.uk/~davej/docs/post-halloween-2.6.txt

  Users who are testing 2.6 kernels for the first time should consult this
  document.

- The ATA RAID drivers (eg the HighPoint RAID driver) have not been ported
  to the new BIO code and are not available under the 2.6 kernel at this
  time.

- cryptoloop doesn't work on highmem machines.  Fixes exist in -mm and are
  queued for 2.6.1.

- There are known performance problems with the default disk I/O scheduler
  which show up when the workload is performing small, random reads and
  writes (ie: database loads).  Largely fixed in -mm.

  In general, the "deadline" I/O scheduler is, and shall remain somewhat
  faster than the default "anticipatory" I/O scheduler with these sorts of
  workloads.  Database admins should consider adding the "elevator=deadline"
  kernel boot parameter.

- There are performance problems due to misbehaviour in the readahead code
  which also impact database-style workloads.  Fixed in -mm, queued for
  2.6.1.

- There are a larger number of as-yet unmerged frame buffer driver fixes.

FWIW it's more a defense against "osdl.org" domain name changes, than 
anything else...  kernel.org will be around decades from now, IMO.

These will appear as Device Mapper modules, Arjan has posted.  I'm 
planning on digging my hands into some of that too, now that Promise has 
opened their softRAID spec a bit.

Re: Linux 2.6.0

[Trond Myklebust]

Congratulations Linus and Andrew...

Will you be posting a plan for how you want the 2.6.x series to
proceed? I gather I'm not alone in having a load of patches that I'd
like to send you ASAP...

Here's a brief commentary on the NFS client related sections in your 2
todo lists, as well as on outstanding client issues:

Must fix:
  - The mmap-versus-truncate NFS problem appears to be a lot more
    difficult to reproduce these days. I need a call for testing to
    verify that the problem still exists.
  - I'm mystified by Andi's comments about RPC having lots of
    uninterruptible waits. It sounds to me as if he is confusing the
    "soft" and "intr" options. The two are very distinct...

Should fix:
  - The VFS support for atomic open() has already been merged by Linus
    (as well as the NFSv2/v3 support). I still have a couple of
    trivial bugfixes for the VFS case (one place where we used O_READ
    instead of FMODE_READ, and one place where the "intent" is not
    filled in at all). NFSv4 support needs for atomic open to be
    merged in (this will fix several NFSv4 file creation races).


Not listed in either:
  - There are a few lockd fixes that need to be forward-ported from
    2.4.x.

  - A *lot* of progress has been made on the NFSv4 client. I would
    very much like to merge this into 2.6.x ASAP, since it concerns
    rather critical subjects such as adding support for locking, and
    reboot recovery (as well as lots of stability fixes). What are
    your feelings on a timeframe for this sort of thing?

  - The RPCSEC_GSS support for NFSv2/v3 was merged in before it had
    been thoroughly tested and reviewed. It contains a couple of
    serious bugs that need to be ironed out.

If you want info beyond this mail, then my current set of NFS client
patches may be found on

   http://www.fys.uio.no/~trondmy/src/Linux-2.6.x/2.6.0-test11

The file HEADER.html contains a list of patches and a brief
description of what each patch does. That should give an idea of how
much is currently outstanding (I still expect the list to continue
growing - I'm still working on several NFSv4 subtopics).

Cheers,
  Trond

Let's first see how embarrassing the next week proves to be...

> like to send you ASAP...

I believe that the processes we've all been using for the past year have
worked well (invitation here for people to disagree).  So any changes we
make to that process shouldn't be arbitrary.

I expect that until 2.7.0 forks, Linus and I shall continue to work 2.6.x
in much the same manner - that's what I'd prefer, anyway.

Obviously, the threshold for merging things into 2.6 becomes higher, and
large changes will be rejected pending more review and testing.  I shall
continue to run an alternate tree for the provision of that testing
service.

Generally, we should expect that there will be large changes across the 2.6
lifetime - it is unrealistic to believe otherwise.  We just need to find
the processes to absorb those changes (and feed them into or from 2.7.x)
without breaking stuff.  We've done that fairly well across 2.5 I think.


We should sit tight for the next week or so, in case we need to rush out a
2.6.1 for brown-bag bugs.  After that I need to shrink the -mm patchset
rather a lot.

Nick has been maintaining these lists lately - hopefully he can send me an
update for NFS, thanks.

I doubt that people will be critially dependent on NFS4 client
functionality in 2.6 for a while, and your changes will only affect NFS4,
so go wild.

If the change was more intrusive then it would be better to
maintain+develop it in -mm until we've all happy, then merge it across.

Thanks... There are some fairly major changes to the NFS attribute
revalidation that I'm working on right now, and that will be likely to
come in the second category (as they affect NFSv2/v3 and v4). They
promise some definite caching wins, though, so I'll try to push them
into 'mm' as soon as I'm satisfied with their stability...

All the rest of the patches should come in the first category, though
I'll make sure that I label any NFSv2/v3 changes clearly FYI.

Cheers,
  Trond

I think that's vastly optimistic. As Hans has reported, it's still
pretty alpha as yet. And you can thank him for not releasing it until
he's happy with it!

I would guess it will be in 2.7 first, and backported when stable, but
that's sure not my call, so feel free to disagree.

I don't think it is vastly optimistic, I hope we can send something in 
next month, but you probably know how hard it is to estimate the time to 
the last findable bug for a large project like ours.

Not to mention the months long period of actually getting user testing
and fixing all of those bugs before it's qualifiable for kernel
inclusion.

I hope you don't expect to actually have something that's worthy of
being merged into 2.6.x in a months time?

I would hope it could go into mm though...  That would give a good 
test base.

Have you looked at the stability of the typical experimental feature?  
If we used that as a guide, we'd have sent it in 3 months ago.....;-)

We will have something we think is appropriate for inclusion as an 
experimental feature very soon now.  Because our test scripts have 
become much more sophisticated, it means more when we say we cannot 
crash it, and it will go from experimental to stable faster than V3 
did.  I won't predict how fast.

I don't think that's true. Plus, a file system (even more true in the
case of reiser4) is a huge complex beast. A driver is a lot less
complex.

Well v3 was merged too soon to, but at that time there was a big motive
to do just that - get a journalled fs in the kernel. With v4 that just
isn't the case.

I don't doubt you have great testing scripts, but nothing beats real
life testing.

Hey, could a List of Lists be put on kernel.org?  I'm not looking forward
  to having to fish through the thread again to find the appropriate list
  when I get up the courage to try 2.6.0 on my workstation again.  :)

Most of them are (and should be) mentioned in the MAINTAINERS file

Please use <linux-dvb@linuxtv.org> for everything related to the DVB 
subsystem and DVB drivers (ie. drivers/media/dvb).

I have a bunch of patches regarding the DVB subsystem and the various 
drivers here. They have accumulated because I did not want to disturb 
Linus with "misc fixes in driver foo" patches.

Additionally, we (ie. the LinuxTV.org project) are planning to remove 
all compiled-in firmware blobs and instead use the new firmware loading 
facilities. I have a patch for the firmware loading here, too.

Can you please tell me if and when I can send you these patches?

For your information: the DVB subsystem and the drivers are hosted at
http://linuxtv.org/cgi-bin/cvsweb.cgi/

The driver can be used under 2.4 and 2.6 as well and is used mainly in 
Europe. In the past, I simply sent the patches to lkml and Linus 
directly. Except Alan Cox and Christoph Hellwig apparently nobody cared 
about this, perhaps mainly because the DVB system does not affect any 
other subsystem.

There was a thread against 2.6.test11 about some issues with MD & DM.  Also
there was one report of problems with ext3+MD.

I don't use LVM or DM, so I'm interested in the second case.

There was a raid5 problem that could trigger under xfs or any
filesystem over DM, and the fix for that is in 2.6.0

I am not aware of a problem with ext3 over MD without DM in between.

Diskstats inconsistancy between 2.4.23 & 2.6 was: Linux 2.6.0

[Mike Fedyk]

A while back there was a flamewar about adding diskstats to
/proc/partitions, and so /proc/diskstats was created, also it is a config
option in 2.4.  In 2.6, the stats are in /proc/partitions, but there is no
/proc/diskstats or config option.

Is /proc/diskstats going to be forward ported?

I have converted dongle drivers on disk here. So far I was holding back 
basically due to:
* 2.6.0 freeze
* neither hardware nor testers to do even basic validation
* wait for tx-lock and rawmode fixes to get applied first so we would 
  hopefully get some more feedback and trust in the infrastructure.

If you would like to accept it now I'd sent patches this weekend.

Yes, tekram-sir is reportedly working now with those patches.

> 	o IrCOMM disconnect race condition Oops ; todo

After some user provided helpful information off-list I found out it gets 
triggered when the app doesn't close the ircomm-fd before exiting.
Just do "cat /dev/ircomm0" and kill -9 the cat to see.

Below my current experimental patch. It works for me and I've got an user
confirmation meanwhile. It's definedly an improvement and I do think it is 
as safe as we can get without reworking the whole ircomm-locking...
