I am sorry for delay.

Now I am testing for same problem with  2.6.27-rc6.:
1. On different MYSON Technology Inc SURECOM EP-320X-S 100/10M
Ethernet PCI Adapters
2. On different Linux PCs
3. With different Ethernet switches which supports 100 Mb
4. With different CAT 5 ethernet cables which supports 100 Mb
5. Also checking old patches on fealnx as per Jeff.

And it seems, I am getting following error, with few ethernet switches
and cables and when I switch ethernet cables  :
"NETDEV WATCHDOG: eth0 (fealnx): transmit timed out
eth0: Transmit timed out, status 00000000, resetting..."

Now I am trying to confirm that problem is coming from ethernet
switches and cables.

I am also facing one more Issue :

With same 100 Mb ethernet switch and cable my another NIC run at 100
Mb/s and full duplex but MYSON Technology Inc SURECOM EP-320X-S
100/10M runs on 10 Mb/s and half duplex.

I debug fealnx it says : PHYType 1 duplex_mode : 2 line_speed : 2
crvalue : 0xe40e61 bcrvalue : 0x10 imrvalue : 0x46c flags : 0x1

So it is saying duplex_mode : 2 (full duplex) and line_speed = 2
(100M) then why I am getting 10MB half duplex ?

Yes, I still see this build error.
What would it take to have Bjorn's patch merged into mainline?

Well, send a request to Andrew I think (with the patch appended).

Thanks for pointing out the fix that should have been obvious,
Dave.  That's a much better solution than sprinkling #ifdef
CONFIG_PNP through drivers.

I have tested parport_pc and also tried with pcmcia_cs, only thing I
get is disappointment. So I give up :-(

Now I switched to usbserial.
usbserial drivers are working great !!

Now I do not want to use parport_pc and pcmcia_cs atleast for 2 years,
I hope in 2 years this will be solved ;)

In the mean time, If you think my problem is solved just ping to me I
will test and let you know the results.

Thank you for all your support and help.

Jaswinder Singh.

Numbers from my Q6600 Aldi supermarket box (hm, your box is from different shelf)

tbench -t 60 4 localhost followed by 4 60s netperf TCP_RR pairs, each pair
jabbering on a separate port and affine to a separate CPU.  Configs are
as close as I can make them, all kernels built and tested today by
identical userland.

I spent two weeks chasing various and sundry netperf numbers recently,
only learning in the process that netperf is _utterly immune_ to
bisection.  Tbench numbers don't look promising for bisection from here.

Note to quixotic self: destroy log immediately lest you be tempted.

P.S. fwiw, scheduler difference between these two kernels is practically
nill.

Apparently stupid for netfilter.  Uninteresting to this thread I
suppose, so disregard.

Don't hold your breath, but after putting my network config of a very
severe diet, I'm starting to see something resembling sensible results.

Turns off all netfilter options except tables, etc.

Since 2.6.22.19-cfs-v24.1 and 2.6.23.17-cfs-v24.1 schedulers are
identical, and these are essentially identical with 2.6.24.7, what I
read from numbers below is that cfs in 2.6.23 was somewhat less than
wonderful for either netperf or tbench,  Something happened somewhere
other than the scheduler at 23->24 which cost us some performance, and
another something happened at 26->27.  I'll likely go looking again..
and likely regret it again ;-)

Math ain't free is part of it, though apparently not much.  For me,
tbench regression 22->27 is ~10%, and netperf regression is ~16%.

lose a bit, preempt haters gain a bit.  Performance shift.

Bisecting 26->27 yet again turned up a repeatable downturn in netperf
throughput.  There is no difference at this point with tbench. 

Bisect says first bad commit is 847106f, a security merge.  Post

I assume that c142bda458a gave a good results as well...

One additional sanity check could be to rebase security 6f0f0fd4963 on top 
of the c142bda458a and then see if bisection among those security commits 
on top yields to the the same result... Though I doubt it can change much 
because there was not that much relevant non-security things in the merge 
in question.

    security: remove register_security hook

    The register security hook is no longer required, as the capability
    module is always registered.  LSMs wishing to stack capability as
    a secondary module should do so explicitly.

perhaps re-test commit 6f0f0fd49 and its parent commit, 93cbace7a0.

It looks like a potentially bogus bisection result, but _maybe_ it has 
relevance: changes the size of "struct security_operations", which could 
have alignment and layout effects on all sorts of kernel variables, 
kmalloc sizes, etc.

This may well be a mythical creature infestation for all I know ;-), but
it's address is somewhere in the 2069f45..847106f block, 316 commits,
none of which look like they should be the least bit interesting to
netperf.  I reverted this particular commit in 27.git, got the expected
result.  Looks like I'll keep poking at it, can't seem to resist.  Grr.

are you sure it's 2069f45..847106f? Filtering out the 
likely-uninteresting commits:

git log --pretty=format:"%h: %s" 2069f45..847106f | grep -viE \
'block|alsa|pcmcia|sound|Merge|iosched|blk|DAC960|scsi|s390|paride|pktcdvd|filter|cdrom|drm'

gives us:

 7daf705: Start using the new '%pS' infrastructure to print symbols
 6f0f0fd: security: remove register_security hook
 93cbace: security: remove dummy module fix
 5915eb5: security: remove dummy module
 b478a9f: security: remove unused sb_get_mnt_opts hook
 32502b8: splice: fix generic_file_splice_read() race with page invalidation
 8b3d356: ramfs: enable splice write
 a144ff0: xen: Avoid allocations causing swap activity on the resume path

which really only leaves that security commit your bisection fingered. 
Which _slightly_ raises its likelyhood of being implicated. Structure 
size changes can move two formerly far-apart netperf-relevant symbols on 
the same cacheline, which can start cache ping-pong-ing badly.

It wouldnt be the first such incident - alignment changes impacting 
macro benchmarks. (and it's hard to find it as the thing that changes 
alignment/size/sharedness might be something totally unrelated)

It's still a bit too early to say this for sure though ...

Yeah, as sure as I can be.  I've built both (et al) kernels several

I sure hope it's something like ping-pong, it's driving me NUTS.

How about dividing the problem to smaller blocks then by restoring

Well, what I've done is check out the "bad" tree, reverted every darn
commit between there and the "good" tree, and then reverted the reverts
so I have a nice merge-free line and don't have to remember to think
backward.  (probably sounds silly to git-foo masters)  I'll try
bisecting that in the a.m. and see what happens.

This was my initial idea (which was mainly an error from my part as I 
misread some shaids and midunderstood that the first regressing would be 
the merge instead of the actual change), but in here I meant taking parts 
of the 6f0f0fd on top of 6f0f0fd^. The most easiest way to do that 
actually might be to do in fact the opposite, ie., but some of the 
datastructure/layout changes back on top of 6f0f0fd and see if the 
performance get restored (besides testing the Eric's patch).

It bisected to 1c9ce52.  Reverting that in 27.git had the expected
result, nada.  Full bisection/test log below - you can jump straight to
post run sanity checks.  I'm torn between building a straight line tree
from v2.6.26 through git.today and bisecting that sucker, or exorcising
netperf from my box and swearing a sacred oath to never download the
damned thing again.  Nuking netperf is most attractive option.

BTW, the reason it's revert revert is that I reverse bisected the revert
tree yesterday, and it emitted the same darn result.  I immediately said
"yeah right, ya screwed up", and created the revert revert tree to make
sure I couldn't fumble negation.

gcc compiling something slightly differently would be a nice theory but 
it sort of breaks down now as this commit touches only one .c file...
In the past when I did some static inline .h -> .c uninline sizing tests
I noticed that some changes happened also in places which should have been 
quite much unrelated. Though all the changes were minor anyway (in the 
places I did look), e.g., routed the conditional paths slightly 
differently and added one xor clear reg.

Could you please try following patch ?

[PATCH] security_ops moved to read_mostly section

"struct security_operations *security_ops" should be moved to read_mostly 
section in order to NOT let it share a cache line with higly modified variables.

Yeah, the driver wasn't changed about this.

Basically it's a warning message that CPU usage got higher due to
somehow wrongly behaving hardware.  The driver behavior itself didn't
do anything wrong.  That is, if the driver didn't show it, you
wouldn't have noticed any change (or noticed improvements in some apps
:)

Of course, it would be ideal if we can add a perfect workaround for
it, but right now, I have no idea what to do better.  So, I don't
think it's worth to keeping this open as a regression.


thanks,

Takashi

I'm sorry for not replying sooner. This is current status: Problem was
never resolved. I tried to bisect, but I only ran into other problems
with either config not being supported for my machine prior to certain
date while trying to find a good bisection point. It's been a while
now, so I don't remember everything exactly, but I may try to
reproduce it tomorrow on the latest -git and see what comes up.

Will report back as soon as I have more info. Thanks,


Vegard

please refer to http://bugzilla.kernel.org/show_bug.cgi?id=11471#c22

I think this might be a regression caused by namespace changes which we 
addressed in SELinux policy.  Which distro version & policy version is 
this seen with?

By which I mean, this was caused by a non-SELinux change to the upstream 
kernel many, many eons ago.

As mentioned in the bugzilla, any related avc messages would be useful.

hm, seems that 2.6.24 is OK but 2.6.25 is not.  I must have missed the
bug when testing 2.6.25-based kernels.

I started a git bisection search but after half an hour I hit bad
bisection breakage: a complete machine hang in fib_rules_init().

What we actually need to see is the output of:
/sbin/ausearch -i -m AVC -sv no

However, the most likely explanation is simply that when /proc/net was
changed from being a directory to being a symlink to /proc/self/net,
that introduced an additional permission check on accesses
of /proc/net/<whatever>, namely the read check on the symlink itself.
And since that check wasn't happening on /proc/net accesses with older
kernels, older policies didn't allow it.

As to why others haven't reported it, I expect that they have updated
their policies to newer ones that allow the necessary access.  The fact
that legacy distros wouldn't have such updated policies isn't surprising
- they don't push updates to those distros for new kernels.  FC5 and FC6
are both EOL'd, right?

In any event, we didn't change anything in SELinux - the change was
elsewhere (in the proc/net implementation).  Don't blame the messenger
please.

BTW, if the explanation above is correct, then a user can allow this
permission in their own policy by creating a local policy module and
inserting it, ala:
$ cat fixprocnet.te
policy_module(fixprocnet, 1.0)
require {
        attribute domain;
        type proc_net_t;
}
# Allow all domains to read the /proc/net symlink.
allow domain proc_net_t:lnk_file read;

$ make -f /usr/share/selinux/devel/Makefile fixprocnet.pp
$ /usr/sbin/semodule -i fixprocnet.pp

Requires selinux-policy-devel to be installed.

Running `ls -l /proc/net' on the FC6 machine produces:

Vanilla FC5 broke and vanilla FC6 broke.  Did vanilla FC7, 8 or 9 break?

http://smolt.fedoraproject.org/static/stats/stats.html shows 11,000-odd
people running FC5 and FC6.  It would be incautious to assume that all
those people have updated their selinux rules.

And _requiring_ people to update their selinux rules to fix a
kernel-caused regression is a pretty big deal for some people, I
expect.

Then again, given that this regression has been out there since 2.6.25,
I guess not too many people are hurting from it.  But we suck.

Just so I'm clear on the context of the problem, it sounds like if a FC5 
(I'm limiting myself to FC5 for the moment) user upgraded to a recent 
(2.6.25+) kernel (non-distro supplied in the case of FC5) then they 
will run into problems unless they also upgrade their SELinux policy, 
yes?

If that is the case I'm not sure it is really that big of a deal.  Maybe 
I'm in the minority here, but in my mind once you step away from the 
distro supplied kernel (also applies to other packages, although those 
are arguably less critical) you should also bear the responsibility to 
make sure you upgrade/tweak/install whatever other bits need to be 
fixed.

We suck?  Maybe, but some explanation about why we suck in this 
particular case would be helpful as far as I'm concerned.  I don't 
really care about identifying the guilty suckees, I'm more interested 
in finding out what happened to cause us to suck because of this.

Agreed.  I believe we carefully gave selinux the same paths for /proc/net
that it had before so I don't know why this affects user space.

I know we had some selinux review when we made the change.

That only true if the 2.6.25+ kernel.org kernel is
backward-incompatible with the distro kernel.

Nope.  Releasing a non-backward-compatible kernel.org kernel is a big
deal.

We'll do it sometimes, with long notice, much care and much deliberation.

We did it this time by sheer accident.  That's known in the trade as a
"bug".

Because we unintentionally and unknowingly released a kernel which is
not compatible with previous kernels without notifying any of our users
and without any consideration or planning.

Yes, often the consequences of the screwup are fairly small, but it's a
screwup nonetheless.



We don't even know the extent of the damage yet.  Which distros were
affected? With which versions of which userspace packages?

Well, there is also the issue of distro specific "special sauce" patches 
which might cause different behavior from the kernel.org kernel, but 
now we are starting to do down a rat hole ...

It is somewhat comforting to know that we can call what we do a "trade",

Okay, so we suck because broke something in 2.6.25 that went undetected 
because current SELinux policies happen to be compatible with the 
breakage.  Gotcha.

Can I assume that the "right" thing to do would be to find the problem 
and revert whatever change caused the issue, yes?  Or are we happy to 
wait and see since the fallout so far has been minimal?

I don't think a revert is justified after all this time.  afaik I'm the
first person to notice the problem, and it's been out there for
multiple months.

However it would be good if we could find some not-completely-stinky
way of making the old userspace work.

otoh, people who are shipping 2.6.25- and 2.6.26-based distros probably
wouldn't want such a patch in their kernels anyway.

Disable selinux?

Get a selinux mystic to update that selinux policy.  I bet it is a one line
change to each the policy about /proc/net as a symlink.

Although I am puzzled why we don't get the same label as /proc/net as a directory
had.

This seems to me to be an extremely fragile selinux user space policy.
In their code that derives security labels from path names.
Why don't we have AppArmor in the kernel again?

Further I don't see how we could have possibly have supported that user space
policy.  How can we apply a user space defined label required by the selinux
policy to a symlink that did not exist?

I expect cd /proc/self/net would work.  In your situation and you can
see /proc/self/net/dev.

Everything here sounds to me like that selinux policy is impossibly brittle.
And anything that is that brittle I have no intention in claiming is a bug
in proc.

I think I explained that one before - in the case of /proc, the only
stable basis we have for deducing the security properties / protection
requirements for a given entry is its name, and its name can be reliably
constructed from the kernel's internal proc_dir_entry tree w/o any
ambiguity or potential for userspace manipulation (unlike the pathname
returned by d_path for a normal file).  I'd agree that it isn't optimal,
but it is what we have.

I'm not blaming anyone here, or trying to argue that the /proc/net
changes should be reverted.  What happened here is that a kernel
interface (/proc/net) changed in a subtle way that had a side effect on
permission checking, and we tried to hide that change at the time (in
terms of ensuring that the new /proc/self/net tree would still be
labeled correctly), and we missed the fact that there would still be a
new check on the symlink read that wouldn't be covered by existing
policy.

I'm not arguing that this is a bug in proc or in selinux for that
matter.

I do however think that the mantra that we can't require users to update
policy for kernel changes is unsupportable in general.  The precise set
of permission checks on a given operation is not set in stone and it is
not part of the kernel/userland interface/contract.  Policy isn't
"userspace"; it governs what userspace can do, and it has to adapt to
kernel changes.

Users who are willing/able to run the latest kernel on their own w/o
waiting for a coordinated update of kernel and policy from their
distribution ought to be able to create a local policy module - it isn't
rocket science, and they can always fall back on audit2allow if they
need to do so.

I should note here that for changes to SELinux, we have gone out of our
way to avoid such breakage to date through the introduction of
compatibility switches, policy flags to enable any new checks, etc
(albeit at a cost in complexity and ever creeping compatibility code).
But changes to the rest of the kernel can just as easily alter the set
of permission checks that get applied on a given operation, and I don't
think we are always going to be able to guarantee that new kernel + old
policy will Just Work.

I know of at least 2 more directories that I intend to turn into
symlinks into somewhere under /proc/self.  How do we keep from
breaking selinux policies when I do that?

For comparison how do we handle sysfs? 
How do we handle device nodes in tmpfs?
Ultimately do we want to implement xattrs and inotify on /proc?  
Or is there another way that would simplify maintenance?

I suspect we could tweak the logic in selinux_proc_get_sid() to always
label all symlinks under /proc with the base proc_t type already used
for e.g. /proc/self, at which point existing policies would be ok.

> For comparison how do we handle sysfs?

Unresolved; presently has a single label for all nodes.
See https://bugzilla.redhat.com/show_bug.cgi?id=228902
for prior discussion of fine-grained labeling support for sysfs.

> How do we handle device nodes in tmpfs?

udev has selinux support - looks up the appropriate context in a
userland config file (file_contexts) via libselinux matchpathcon(3) and
sets it upon creation.  tmpfs has long supported getting/setting
security.* attributes.

> Ultimately do we want to implement xattrs and inotify on /proc?  
> Or is there another way that would simplify maintenance?

If proc supported setxattr, then I suppose early userspace could label
it instead of the kernel needing to determine a label internally.  But
not sure how we'd cleanly migrate to avoid breakage with old userspace.

so if proc is mounted anywhere other then /proc the selinux policy would 
do odd things?

No, the logic doesn't care where proc is mounted.  Only the name
relative to the root of proc is used.

FWIW, a fix for this issue has been applied to:
git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/security-testing-2.6#next

The particular commit can be viewed at:
http://git.kernel.org/?p=linux/kernel/git/jmorris/security-testing-2.6.git;a=commit;h=ea6b184f7d521a503ecab71feca6e4057562252b

This should address not only the /proc/net breakage but also any future
changes to turn existing directories into symlinks.

Looking at this discussion closely from what I see selinux is designed
to work on the principle of least privilege.  If you make a user space
visible but compatible change, selinux will keep the system until
you update selinux.  Is selinux exposing too much to user space?
    
selinux was taken into consideration when the change was made.
The patch was even updated with feedback from Stephen Smiley.

That's fine.  In case it turns out to be a regression, it's better to list it

It should be. The patch listed should be good as far as I'm concerned 
but needs to be pushed by Bjorn as PnP mainatainer. Generally speaking 0 
wouldn't be a _very_ necesarily invalid value it seems so it's maybe not 
very nice.

If someone wants a changelog though, this should do:

===
PNP: avoid checking unitialized BARs for conflicts

Avoid checking a PCI BAR for conflicts if the BIOS left it unitialized.

Re: [Bug #11557] Controlling backlight on thinkpad x60

[Matthew Garrett]

I don't think this is a regression. The correct way to drive this 
hardware has always been through the ACPI video driver. The fact that 
thinkpad-acpi would also attempt to drive it was a bug.

I'm pretty sure thinkpad-acpi is older then ACPI-video. So yes, I
believe this is a regression, but it may be pretty old one.

I got around to try kexec and found that on 2.6.27-rc5, without
Yinghai Lu's patch, when I kexec while forecdeth is loaded I get the
following when the new kernel tries to load the module (on my Asus
M2N-SLI Deluxe):

If I rmmod forcedeth before kexec, it loads fine later.
This is with MSI enabled:

Maybe also calling nv_restore_phy() and/or pci_release_regions() in
the shutdown hook would help.

TODO:
Try with the patch, maybe try nv_restore_phy, test if WOL is
affected by the patch.

I just tried with the patch and both options above in the shutdown
path and the kexec'd kernel still had the same problems as above.

Interestingly the message comes from drivers/pci/setup-res.c, where
it updates the BAR register and reads it back to make sure it was
updated and somehow reads back zeroes?

I wonder what's going on there, that should never happen AFAIK...
Maybe the pci device was not properly reenabled, but OTOH when I
just rmmod before kexec it seems to work and nv_remove also calls
pci_disable_device()...
