Linux 2.6.6-rc3

Linux 2.6.6-rc3

[Linus Torvalds]

s390, cifs, ntfs, ppc, ppc64, cpufreq upates. Oh, and DVB and USB.

I'm hoping to do a final 2.6.6 later this week, so I'm hoping as many 
people as possible will test this.

	Thanks,

		Linus

    not use stale data while someone may be modifying the file on the
    server.
  o fix double incrementing of transaction counter

    search results displayed on very large directories. Fix cleanup of
    proc entries.  Add config parm to allow disabling negotiating Linux
    extensions
  o allow disabling cifs Linux extensions via proc

  o Fix global kernel name space pollution
  o Check return on failed dentry allocation.  Suggested by Randy
    Dunlap
  o Allow null password string pointer and passwords longer than 16
    bytes
  o finish handling commas in passwords
  o finish off mount parm sep override
  o Fix caching problem with multiply open files from different clients
  o Relax requested CIFS permissions on open to simply request
    GENERIC_READ and GENERIC_WRITE (instead of GENERIC_ALL which can
    unnecessarily conflict with share permissions by asking implicitly
    for take ownership and other unneeded flags)

    explicitly and port field unitialized

  o clean up compiler warnings
  o Add missing description about how to specify credentials file
  o Invalidate readahead data properly when file closed, but other
    client changed it on server
  o Send NTCreateX with ATTR_POSIX if Linux/Unix extensions negotiated
    with server.  This allows files that differ only in case and 
    improves performance of file creation and file open to such servers
  o Fix 20 second hang on some deletes of reopened file due to
    semaphore conflict with vfs_delete on i_sem
  o fix merge problem with 2.6.5 (rename of page struct field list to
    lru)

  o free cifs read buffer on retry
  o Fix major page leak in read code caused by extra page_cache_get
    call
  o check permission locally for servers that do not support the CIFS
    Unix Extensions (allowing file_mode and dir_mode to augment the
    server permission check, by doing local vfs_permission check)
  o Remove 64 bit compiler warning
  o Remove "badness in remove_proc_entry" warning logged on module
    unload of cifs
  o Add in cifs fcntl handling to fix remote dnotify problem
  o Do not cache inode metadata when cache time set to 0 (fix hardlink
    count caching)
  o Retry 2nd time after failure on correct port
  o RFC1002 fixup
  o exit from waiting on smb response when session dead
  o Update change log for 1.10 cifs vfs
  o proper rc on host down

I can't see that
http://marc.theaimsgroup.com/?l=linux-kernel&m=108308929211499&w=2 or
an equivalent fix has been included yet.  It would be nice to have it
fixed before the next release.

OK, I'll bite. Building using :

loop-AES 2.0g has refused to compile since 2.6.6-rc1. No problems up
through 2.6.5. The make script cd's to the kernel source root, then
can't find any of the kernel include files, and it's all downhill from
there...

SuSE 9.0 on a ThinkPad X23. I'd be glad to provide more info if it would
help.

This is an external module - right?
Could you mail me privately the Makefile used, or even better

Full package:
http://loop-aes.sourceforge.net/loop-AES/loop-AES-v2.0g.tar.bz2

Patch to fix build problem:
http://loop-aes.sourceforge.net/updates/loop-AES-v2.0g-20040412.diff.bz2

New version of loop-AES will be released shortly after final 2.6.6 kernel is
released.

Wow, this enigmatic piece of code finally got in.
Now everybody that has been looking for it has a chance to check it
out.

Hi Jari.
I took a look at how you use the build system in the 2.6 kernel.
Inherited from the 2.4 days you assemble the commands yourself,
which is plain wrong in a 2.6 kernel.
The only sane way to build external modules with a 2.6 kernel is
to utilise the kbuild infrastructure.

For your reference here is a Makefile that I used to compile your
module (made a symling for loop-patched.c file).

To compile the kernel I used:
make -C /home/sam/bk/v2.6/ M=$PWD
[Assumes latest linus kernel - 2.6.6-rc3]

For older kernels append the modules target

This has the added benefit that Module versioning is also supported.

#########################
# Minimal kbuild Makefile for loop-AES

EXTRA_CFLAGS := $(LOOP_AES_CFLAGS)

obj-m := loop.o

i586-$(CONFIG_M586) := -i586
i586-$(CONFIG_M686) := -i586

loop-y := loop-patched.o aes$(i586-y).o glue.o md5$(i586-y).o

##########################

I see in the Makefile that you do a lot of tricks to support various
kernel versions. But they all end up in a few defines for the C compiler,
which you just needs to supply in the variable LOOP_AES_CFLAGS.
[And some file massaging whaich is done before starting the build]

What I would recommend you to do is to move all your backward compatibility
stuff and general rules to a file named 'makefile'.
Then provide individual Makefiles for each kernel version:
Makefile.2.4, Makefile.2.6
Then symlink Makfile to the right one and build the module.

This would clean up your Makefile and give you correct usage in 2.6

Thanks much for the quick response. With the loop-AES makefile patched,
loop-AES and 2.6.6-rc3 are happy together.

One last question: Is there a reason there is no mention of the
compile problem or presence of a patch on the loop-AES sourceforge home
page (http://sourceforge.net/projects/loop-aes/)? Or is this common
knowledge that everyone is supposed to know about sourceforge projects?
At least with this thread, Google searches will no longer come up empty.

Now all I need is an APM implementation which suspends while on A/C
power and I can stop playing with kernel releases and concentrate
on work.

Thanks again!

Vince

Would it be possible to get results for the latest 2.4 to compare it
with? To see if it looks like it's doing better, worse or thesame. 2.4
comes out less often so it shouldn't be much of a hassle (right? :).

OSDL is nearly complete with their automated tests.  Tests 
completed so far:

LTP          1-way, 2-way
contest      1-way, 2-way
reaim        1-way, 2-way, 4-way, 8-way
lmbench3     1-way, 2-way
bash-memory  1-way
iozone       1-way, 2-way
tiobench     1-way
hackbench           2-way, 4-way
dbt2 (SAP)                 4-way
dbt3 (PostgreSQL)          4-way

I have taken a quick look at the results and I see no degredations
from 2.6.6-rc2 and the performance looks much better than the 
2.6.5 kernel for dbt3 (as reported earlier).

The URL to the test results (a dashboard of info) is located here

http://www.osdl.org/projects/26lnxstblztn/results/

Click the link along the patch-2.6.6-rc3 row under a desired test
if you care to scrutinize the results further.

The 70% dbt3 improvement is extremely fishy.  Yes, there are things in
2.6.6-rc3 which could improve database workloads by that much, but dbt3
doesn't appear to be using them.

Again, the vmstat traces indicate that after a run on 2.6.6-rc3 we have a
full gigabyte less used pagecache than with 2.6.5.  In both cases there is
still a lot of free memory.  Which tends to indicate that the -rc3 run was,
for some reason, not an equivalent workload - it's using a smaller dataset.

I'd suggest that you double-check these results, try and work out why the
-rc3 run is touching less data.  Maybe go back and redo the 2.6.5 test?

That's a good plan.  We will do a re-run of 2.6.5 and get back to 
the list.

Done and posted.  

The DBT3-pgsql test will fail on 2.4 at this time due to LVM2
and PostgreSQL interoperability issues with the 2.6 kernel.  We
have been focusing on the 2.6 kernel, so we have not had a chance to
get that test working on 2.4, but if anyone wants to fix it for 2.4,
we'll be more than happy to run it.

It cannot find the file: isoch.c
Did you do a recursive check-out before building the kernel?
It's in my tree here.

Well, yes..

I thought it was because last patch applied, when in fact it was because
of coping kernel tree to my own directory before I applied it...

-rw-r-----    1 root     root        13235 2004-04-04 06:38 isoch.c

Anyway false alarm, sorry...

Don't do that please. That will break all the user space
programs who use asm/unistd.h to define own system calls
(it is quite common).

Make it conditional on __KERNEL__

err, that was just a "technology demonstration".  Obviously there's a lot
more involved.  Such as fixing up all the other architectures and then
killing off all the `errno' users.
