Sounds like a bug yes. I would suggest to switch it to the stricter

That might even have a deeper meaning. I remember there were
subtle bugs in this area long ago. But likely it is a bug too.

* libata/sas patches
From: Brian King @ 2006-05-22 14:35 UTC (permalink / raw)
To: linux-ide
I just uploaded my updated libata patchset to support attaching
SATA devices to SAS HBAs. It's only lightly tested at this point.
I still need to give it another review myself and make sure
I'm happy with all the error cases, but the base function
is working for me, so I figured I'd post the link. I'll
hopefully submit the code to the list soon.

Hello!

Been there... ld-linux in glibc-2.3.2 is broken: it does not understand
relocatable VDSO. If vsyscall-sysenter.so is not absolute, which is
the case with exec-shield patch, it dereferences not-relocated pointers
in .dynamic and segfaults.
BTW original Gerd Hoffman's patch as submitted by Rusty works
with libc-2.3.2, it generates good absolute VDSO.

Yep... too coincidental. I'd say it has _something_ to do with Xen.
I've been doing different things on my side to try to reduce the

I don't know enough about the tty system to find the problem, but it
seems to me that the tty structure might be released too soon.
We have a hotplug script that starts ppp on connect, and we can
reproduce this by repeatedly plugging and unplugging the ipaq.

Taint on write to /dev/mem, perhaps? I don't think DMIdecode needs to
scribble on /dev/mem, does it? (Figure if a userspace program runs OK
on a recent Fedora or RedHat kernel, it doesn't need to scribble on /dev/mem
too much, because the vast majority of it is lopped out via a patch....)

Yes, so instead of one method of telling the kernel we want to have kgdb
asap, and one method of implementing that on all architectures we have
the command line parsed sometimes (and we just drop right in), other
architectures we need to write something to set a flag we check later,
and someone else writes something different for this on yet another
platform and we're back to where we started from. That's my fear :)

There is an alternative method that i've used and is infallible detecting p2p.
Find out what is *not* p2p traffic in your network and give it the appropriate
bandwidth/priority. Then the rest will be p2p traffic.
This is the same approach used to build firewall rules, which is close all
traffic and start open ports/protocols till all works ok. So at first maybe
there will be some false positives, but with yours clients feedback and a
Little of network analysis all goes to the right place.
Some clues on what is not p2p:
- packets with size<100bytes
- tcp ports 80,21,22,25,110 and so on...
- all udp, some p2p protocols use it for control but AFAIK is not used in data
transfers, and if it is, you can still use a size rule ie: udp<900bytes
- other protocols as icmp igmp esp...

I agree, I think we can get by with only the ia64 changes in the
increase_reservation call. The other option seems more fragile. Keir,
would you include the first chunk of Kevin's patch as a temporary
solution until we have better ballooning support on xen/ia64 (should be
soon)? Thanks,

* [linux-lvm] Removing a Bad disk from LVM w/o a new disk
From: Ow Mun Heng @ 2006-05-22 14:24 UTC (permalink / raw)
To: linux-lvm
Current situation is that I have a bad disk /dev/sdb1 in an existing lvm
partition. (sda1/sda4/sdb1)
I would like to remove it from the VG. (There are no free PE anywhere.
I've maxed it out.)
I've already reduced the existing VG to the size of sda1+sda4
partition.
I would like to remove entirely the Physical Extents from the volume
group. It doesn't seem like there's a way to do this w/o putting another
disk inside?
I'm sure that's not true. Doing a
$vgreduce storage /dev/sdb1
Physical volume "/dev/sdb1" still in use
I have no idea what/who is using it. fuser/lsof etc doesn't show up
anything.
I actually don't much care about the data, I've already copied it
somewhere else. So, instead of just blowing up everything, I rather take
this as a learning experience.

* [Xenomai-core] New patch for Freescale i.MX21 (csb535fs)
From: ROSSIER Daniel @ 2006-05-22 14:23 UTC (permalink / raw)
To: xenomai-core
[-- Attachment #1.1: Type: text/plain, Size: 794 bytes --]
Hello,
Here is a new release of the Adeos patches for the Freescale i.MX21.
The "extra-"adeos/xenomai patch called linux-2.6.14.imx21_1.1.0.patch
can be used for the support of the i.MX21 board (free standard edition)
to linux 2.6.14
We found out that some changes issued from our first patch (tune_timer,
proper irq virtualization in do_edge/do_irq functions, ...) have been
integrated
into the last release of the official arm patch. BTW, is it possible to
keep our copyright notice somewhere in the arm patch ;-)) ?
The last release includes a way to configure the idle_mode (idle=poll)
in the boot command line and reduces the number of warning at the
compilation (not all unfortunately).
Thanks for your feedback
Daniel

This is pretty much what the audit system does in the kernel. It saves
everything in the context until it decides to output an event. Then it dumps
all records associated with the event into the netlink queue.

Doubtful.

I haven't seen this except when we introduced a bug in the kernel.

The record type has something to do with the meaning of any items.

Yes, I'm glad to see more people use this feature. Please note that there is
an API version number that dictates the format of the records passed through
the event dispatcher mechanism. Right now, the version is 0. It is the 1st 32
bit word sent in the dispatcher header. I should probably add a specification
to my people page so that everyone knows the rules.
Also, the audit daemon can be told not to log anything locally so that its all
done across the network. Its in the auditd.conf man page. The dispatcher is
responsible for adding the machine or host's name if that's needed in the
record.

Not looking at your code...but you probably are referring to munging CWD &
PATH records to create complete path? If not, that's what you need to do.

Just one, at some point I'm going to pick up work again on the audispd
program. It will have a plugin architecture that will allow multiple programs
like yours to share the event data. Its likely to be a couple months before I
start back into it...but I just wanted you to be aware of the long range
plans.
But until then, its fine to grab the event dispatcher hook and use it
exclusively.

When the serial number changes is what I've been using in ausearch/aureport.
The events should all be out within a second. When it decides to dump the
records for a single event, it all happens quickly.

Hi friser,
You need to install the Linux kernel source package before you can build
the ALSA sources. Search your package manager with words like "kernel" and
"source". He should have the required package listed (it's rather big, a
few 100MB).
Regards,
Lars.

/dev/mem is used for all sorts of sane things including DMIdecode.
Tainting on it isn't terribly useful. Mind you this whole user taint
patch seems bogus as it can only be set by root owned processes so
doesn't appear to do the job it is intended for - perhaps Ted can
explain ?
What X needs btw is mmap on PCI mmio bars, teach the X mapping code to
use those instead of /dev/mem is a simple matter of coding as the right
abstractions are in the tree already.
It would need the kernel to also provide a /dev/isa mapping however.

Sorry for the delay, the user has now provided some serial console logs.
Actually there is some good news: somewhere between 2.6.17-rc2 and
2.6.17-rc4, the situation has improved, errors do appear during boot but
the system does reach a login prompt now (previously it was looping
seemingly forever).

There is 1 disk, 2 CD drives, and 1 zip drive. The system is booting

* Extract have_task_perm() from kill and migrate functions.
From: Christoph Lameter @ 2006-05-22 14:21 UTC (permalink / raw)
To: akpm; +Cc: linux-mm
Various kernel function check if they are allowed to do something to another
task. The ones that I have found are
1. The check for kill permissions
2. sys_migrate_pages() checking if a process is allowed to
migrate the pages of another process.
3. sys_move_pages() checking if a process is allowed to
migrate individual pages that are part of another process.
Extract the common code in these checks to form a new function
in kernel/signal.c have_task_perm(task, capability). The check
is successful if
1. The current process has the indicated capability
2. The current effective userid is equal to the suid or uid
of the target process.
3. The current userid is equal to the suid or uid of the
target process.
Note that there are similar checks for uid/gid/euid that are
stored in a variety of structures in the kernel. Maybe those may also
be extracted by a similar function that would not take a task parameter
but an explicit specification of permission ids?
ptrace() has a variation on the have_task_perm() check in may_attach().
ptrace checks for uid equal to euid, suid, uid or gid equal to
egid sgid,gid. So one may not be able to kill a process explicyly
but be able to ptrace() (and then PTRACE_KILL it) if one is a member
of the same group? Weird.
Plus ptrace does not support eid comparision. So explicit rights
for ptracing cannot be set via the super user bit.
Maybe we could consolidate all these checks and make them work in
a coherent way? I dont think I am deep enough into this issue to
takle that though.

Even then I had the impression that stages were pretty much invisible to
users. So that should stay in core-tutorial.txt. Which could use some
revision (Junio had some ideas) but I'm personally more interested in
end-user documentation than developer documentation for now.
So I'd imagined future tutorial parts cannibalizing everyday.txt and the
howto's.

It's not the kernel's knowing about it that I'm interested in, but
userspace systems management applications.
It's essential that management applications running outside of domU's
and the dom0's hosting those domU's to have a stable method of
correlating output from agents running in the domU's with their dom0's.
The UUID's are good for this, but need to be read from xenstore now.
Since I'm interested in <uuid> instead of /vm/<uuid>, I'd like to see
<uuid> by itself in xenstore.
Make sense?

* Setting up udev for a distribution that does not yet suppot it
From: Ryan Melman @ 2006-05-22 14:17 UTC (permalink / raw)
To: linux-hotplug
Hey developers,
Im trying to migrate the distro i use (puppy) across to udev.
I've tried following the general primer however Im finding it too gentoo
specific. speakingto people who use it they also mention that hotplug scripts
are nolonger required to run udev.
is there any documentation about setting up udev from source i.e whats in the
sbin/rc for udev and what is in the base layout files so that i can set up
something simalar for puppy.
how up to date is the general primer and what are the basic setup requirements
to get a system up and running with udev.
thanks
Melmo

we should then patch the /dev/mem driver or something to set this :)

Shouldn't this be CONFIG_UNWIND_INFO? Seems a bit unsymmetric to x86-64
