2.6.16-rc5-mm1

[Andrew Morton]

ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.16-rc5/2.6.16-rc5-mm1/


- A large procfs rework from Eric Biederman.

- The swap prefetching patch is back.



Boilerplate:

- See the `hot-fixes' directory for any important updates to this patchset.

- To fetch an -mm tree using git, use (for example)

  git fetch git://git.kernel.org/pub/scm/linux/kernel/git/smurf/linux-trees.git v2.6.16-rc2-mm1

- -mm kernel commit activity can be reviewed by subscribing to the
  mm-commits mailing list.

        echo "subscribe mm-commits" | mail majordomo@vger.kernel.org

- If you hit a bug in -mm and it's not obvious which patch caused it, it is
  most valuable if you can perform a bisection search to identify which patch
  introduced the bug.  Instructions for this process are at

        http://www.zip.com.au/~akpm/linux/patches/stuff/bisecting-mm-trees.txt

  But beware that this process takes some time (around ten rebuilds and
  reboots), so consider reporting the bug first and if we cannot immediately
  identify the faulty patch, then perform the bisection search.

- When reporting bugs, please try to Cc: the relevant maintainer and mailing
  list on any email.

If neither Greg nor Martin (on cc:) object, I'd prefer this patch to be
replaced with the one in
http://marc.theaimsgroup.com/?l=linux-kernel&m=114102840429459&q=raw

This patch is causing that warning
inotify-lock-avoidance-with-parent-watch-status-in-dentry.patch

It's full reproductible on my system, it appears when I start mozilla
thunderbird (v 1.0.7).

The warning is harmless really. I guess it can be removed.

I guess it is because I don't clear it on +ve => -ve conversions.
We _could_ do that AFAIKS, by hooking into d_delete, but it would
have to be yet another fsnotify hook there because it will have to
be done under lock.

But there is no real gain in doing that.

How could a -ve dentry become the source of a link?  We should be sure we
know why this happened before ignoring it..

The source of a link? That wouldn't get d_instantiate called on it, would it?
I figured this was the destination.

I can reproduce a similar looking oops by unlinking a PARENT_WATCHED file, then
touching it again.

Oh, OK.

What does a patch which clears that flag on the -ve dentry look like?  I
think it'd be best to be paranoid at this stage..

The log is not supposed to say "Intel Corporation".

The controller hardware does not contain a manufacturer string anywhere,
so instead the driver makes up a name based on the current kernel version.  
(Likewise for the serial number; the driver makes up a name based on the
device's path.)

The name you see in the lspci output actually comes from the lspci program
itself, based on a code number embedded in the controller.

It has always been this way, and not just in -mm.

 Hi,

  thanks. It is now fixed as a side effect of another patch. I expect
 to release the new version in a couple of days.

Ok, something is definately broken in this kernel.

If I launch Eclipse (http://www.eclipse.org/) while running a
2.6.16-rc5-mm1 kernel it loads for a second or two and then the box
just locks up solid.

I then went back to my previous kernel, 2.6.16-rc4-mm2, and there's no
problem what-so-ever when running that kernel (everything else
identical) - eclipse loads and runs just fine.

Since I'm in X when the lockup happens and I don't have enough time
from clicking the eclipse icon to the box locks up to make a switch to
a text console I don't know if an Oops or similar is dumped to the
console (there's nothing in the locks after a reboot)  :-(

Unfortunately I don't have a second box to use with serial console or
netconsole, but I'll see if I can somehow get some console messages -
perhaps by slowing down the eclipse load process somehow... I'll see
what I can do and report back when I have more into.
If all else fails and noone on LKML can suggest patches to try and
revert or similar I guess I'll eventually do a git bisect, but I'd
rather try other things first...

The version of Eclipse I'm running is 3.1.2

The problem is completely reproducible (well, at least it occoured 6
times in a row and that's how many times I tried).

Sorry for the lack of detail, but I thought I'd better report the
issue at once and then follow up with details later :)

So why don't just run eclipse from console (DISPLAY=... eclipse), or use atd,
crond... (less common variants)?

I experienced similar symptoms while launching mozilla 1.7.12. I 
found that java was the culprit.

Here is a full dmesg captured by netconsole with the following 
scenario:
- boot to runlevel 1 (init 1)
- launch java (type "java[Enter]", no args).

The first oops is :
BUG: unable to handle kernel NULL pointer dereference at virtual address 00000034

I can confirm that. I just tried visiting a website, that launches a
java applet, with Firefox 1.5.0.1 which resulted in an instant freeze.
So it seems anything Java is a good test case.

Sure, no problem. But it'll have to wait until tomorrow evening for me
- I have to get some sleep now or I won't ever be able to get up and
get to work tomorrow... But I'll test those as soon as I get home
tomorrow.

Re: 2.6.16-rc5-mm1

[Paul Jackson]

I have popped the patch stack back to including:
> trivial-cleanup-to-proc_check_chroot.patch
> proc-fix-the-inode-number-on-proc-pid-fd.patch

but not past that.  It boots now, unlike before with the full patch
stack.

I will continue the hunt.

Meanwhile, on the side,  I have a couple of permission problems to
report to Eric Biederman with apps that are complaining about not being
able to access /proc/<pid>/fd/[0-9]* files when before they could:

 1) Logged in as root, running "/bin/ls -l /proc/*/fd/*"
    causes some complaints.  For example:

    # /bin/ls -l /proc/2868/fd/?
    /bin/ls: cannot read symbolic link /proc/2868/fd/6: Permission denied
    /bin/ls: cannot read symbolic link /proc/2868/fd/7: Permission denied
    lr-x------ 1 root root 64 Feb 28 18:39 /proc/2868/fd/0 -> /dev/null
    lrwx------ 1 root root 64 Feb 28 18:39 /proc/2868/fd/1 -> /dev/pts/10
    lrwx------ 1 root root 64 Feb 28 18:39 /proc/2868/fd/2 -> /dev/pts/10
    lr-x------ 1 root root 64 Feb 28 18:39 /proc/2868/fd/3 -> /proc/sal/cmc/event
    lrwx------ 1 root root 64 Feb 28 18:39 /proc/2868/fd/4 -> /proc/sal/cmc/data
    l-wx------ 1 root root 64 Feb 28 18:39 /proc/2868/fd/6
    lr-x------ 1 root root 64 Feb 28 18:39 /proc/2868/fd/7
  
    I don't recall seeing any similar complaints before.  My first reaction
    is "wtf - I'm root - what's this permission denied error ?!?"

 2) I have an SGI specific application that runs out of init on boot
    that spews out some 50 or so "Permission denied" errors on
    various /proc/<pid>/fd/* files, which it never did before that
    I can recall.

    For example, this app complained:

	Cannot stat file /proc/1688/fd/3: Permission denied
	Cannot stat file /proc/1688/fd/4: Permission denied
	Cannot stat file /proc/1688/fd/5: Permission denied
	Cannot stat file /proc/1688/fd/6: Permission denied
	Cannot stat file /proc/1688/fd/7: Permission denied
	Cannot stat file /proc/2781/fd/3: Permission denied
	Cannot stat file /proc/2802/fd/1: Permission denied
	Cannot stat file /proc/2802/fd/3: Permission denied
	Cannot stat file /proc/2802/fd/4: Permission denied
	Cannot stat file /proc/2878/fd/6: Permission denied
	Cannot stat file /proc/2878/fd/7: Permission denied

    You can see it is not complaining about all the fd's of a task,
    but just some.

    I might be confused in what patches I'm running, but I believe that
    I am getting these permission denied errors with just the patches:

drat - I was off by one in my reporting.

I'll try to get my act together before saying more.

So the function that will be giving you trouble is proc_check_dentry_visible.

The patch should be called something like: 
proc-Properly-filter-out-files-that-are-not-visible-to-a-process

It was the 8th patch on my stack when I submitted it.

Largely what is happening is that I fixed the permission checks that
have been in the kernel since 2.2 so that they work.  I'm not saying
that what I am doing right now is correct but it is something we need
to consider.

The logic is can I access this file in some other way besides through
/proc.

When applied to /proc/<pid>/exe
When applied to /proc/<pid>/root
When applied to /proc/<pid>/cwd

I have some concerns about it's correctness but when applied to
/proc/<pid>/fd/<#>
my only concern is if the checks are complete, or if we even want them.

There may be a capability I need to check that says anything goes.

There are 2 sets out file descriptors that will now be unaccessible.
- Files on internal filesystems like pipefs.
- Files on outside of your filesystem root or filesystem namespace.

If you share the struct file with the process everything should be visible.

We may want different checks for readlink and follow link.

If you want to kill the permission checks to stop the noise for a while
it should be straight forward.

I can't make sense of the above.  Could you elaborate?

And explain how any of these permission checks fail for
a root shell?

Sorry.  What I ment was when applied to the above files the
permission checks are not quite correct because I should check
to see if you share a fs_struct with them, checking for a shared
files_struct for exe,root,cwd is nonsense.

The permission check is not quite in the right place yet
in /proc.

The logical check which I have implemented imperfectly is:
Without going through /proc/fd can I see this file.

Part of the reason this happens now is the old check
unchanged since 2.2 was it only checked to see if the two
processes were in the same chroot.  I made the check test
the actual files that were returned.  Which is much more
correct, and much more likely to prevent information leaks.

> And explain how any of these permission checks fail for

Because I probably need a check something like
if (capable(CAP_DAC_OVERRIDE))
	return 0;
To allow an appropriately privileged root user to do anything.

The short answer is that I bug fixed the permission checks into working
but that is not sufficient for the permission checks to be correct. :(

These checks were previously done so badly they were mistaken for
generic permission checks that all files in /proc should have.  Which
resulted in tons of useless cruft.

At this point the code is working as designed but it is clearly not
working as it needs to.

I am also beginning to think that readlink and followlink
should have different permissions.  Especially to keep fuser
and his friends happy.

I am glad I found this issue with permissions on /proc/<pid>/fd,
but it is clear there is still more todo.

Ok. Now back to hunting bugs that crash the kernel.

I guess you don't need me to test 2.6.16-rc5-mm1.2 since 
2.6.16-rc5-mm1.1 is OK.

Useful, thanks.  So the second batch of /proc patches are indeed the problem.

If you have (even more) time you could test
http://www.zip.com.au/~akpm/linux/patches/stuff/2.6.16-rc5-mm2-pre1.gz. 
That's the latest of everything with the problematic sysfs patches reverted
and Eric's recent /proc fixes.

Ashok, x86_64 and i386 share a lot of code.  Please always perform good

Sorry,

here is one to make it non-static for i386 as well.

Seems to work OK here, with debug settings as in Paul Jackson's report.
No java crash, no fuser -n tcp NNNN crash.  Only thing I see so far is
the proc symbolic link to nirvana permissions thingie.  Box is P4 HT.

This doesn;t look quite corect to me.  First set DCACHE_REFERENCED in
the d_flags and then clear every bit in d_flags except
DCACHE_INOTIFY_PARENT_WATCHED?  Should this be 
"~DCACHE_INOTIFY_PARENT_WATCHED"?

    Thanx...

I'm thinking about it. Implementing it is easy.  Figuring out what the
check for the /proc/<pid>/fd/<#> files should be is trickier.

What disturbs me is that by my current reading of the code all of the
cool file descriptor passing of unix domain sockets is unnecessary.
You can just walk up to any process and open any file it has open.

This includes sockets and pipes and the like, as well as files.

We don't bypass individual file permission checks as far as I can
tell but we do bypass all directory permission checks.

This seems to defeat the concept of using file descriptors as
capabilities.  Heck even plan9 makes you bind your file descriptor
to your filesystem namespace before it was exported.

In the presence of chroot jails and multiple namespaces this is also
possible.

Now maybe this is all fine, and since this is what we have been doing
for years maybe it isn't a security bug, and I can just kill the
check altogether.

My gut says this is an ancient permission checking bug, and I have
started closing the hole.

So if anyone can help me wrap my head around what is expected and why.
I would greatly appreciate it.

The fuser and lsof cases seem to one aspect of it, that I had
not looked at.

Sorry, I forgot about that. With that patch, d_instantiate can still get some
warnings. The following one should fix that and also makes the watch creation
deletion loop-over-all-dentrys ignore negative dentrys too.

I'm not sure what the cleanest way to do this is. I'm fairly sure the vfs
guys do not want a DENTRY_INOTIFY_ flag in fs/dcache.c, so I've added a
comment there.

I also don't know whether or not the inotify guys want parent events on
negative entries. They don't appear to now, so I'll take that as a no.

After the DENTRY_INOTIFY_PARENT_WATCHED debugging stuff is taken out, that
flag will basically be undefined for negative dentrys rather than always
clear (after this patch). I'm not sure whether the vfs people consider that
to be unclean.

[PATCH] proc: Use sane permission checks on the /proc/<pid>/fd/ symlinks.

[Eric W. Biederman]

Since 2.2 we have been doing a chroot check to see if it is appropriate
to return a read or follow one of these magic symlinks.  The chroot
check was asking a question about the visibility of files to the
calling process and it was actually checking the destination process,
and not the files themselves.  That test was clearly bogus.

In my first pass through I simply fixed the test to check the visibility
of the files themselves.  That naive approach to fixing the permissions
was too strict and resulted in cases where a task could not even see
all of it's file descriptors.

What has disturbed me about relaxing this check is that file descriptors are
per-process private things, and they are occasionaly used a user space
capability tokens.  Looking a little farther into the symlink path on
/proc I did find userid checks and a check for capability (CAP_DAC_OVERRIDE)
so there were permissions checking this.

But I was still concerned about privacy.  Besides /proc there is only one
other way to find out this kind of information, and that is ptrace.  ptrace
has been around for a long time and it has a well established security
model.

So after thinking about it I finally realized that the permission checks
that make sense are the permission checks applied to ptrace_attach.
The checks are simple per process, and won't cause nasty surprises for
people coming from less capable unices.

Unfortunately there is one case that the current ptrace_attach test
does not cover: Zombies and kernel threads.  Single stepping those
kinds of processes is impossible.  Being able to see which file
descriptors are open on these tasks is important to lsof, fuser and
friends.  So for these special processes I made the rule you can't
find out unless you have CAP_SYS_PTRACE.

These proc permission checks should now conform to the principle of
least surprise.  As well as using much less code to implement :)

Reverting just this patch prevents the above.

This is with basically unaltered FC5 as of a few days ago.  The audit
patches weren't applied.

What is happening is that both `current' and get_proc_task(inode) are the
same task_struct: `restorecon' is trying to read its own proc files.  But
ptrace_may_attach()->security_ptrace() is returning -EACCES.

So I bodged it in the obvious manner:

And the messages went away.

But I have a bad feeling about these /proc permission changes, Eric.  I
suspect we'll be chasing a gradually decreasing frequency of weird problems
for a long time.


That task_lock() you have in proc_fd_access_allowed() looks very fishy,
btw.  As soon as the lock is dropped, local `alive' becomes meaningless. 
Either that, or the lock wasn't needed.


btw, it's surprising (to me) that security_ptrace(t1, t2) fails when
t1==t2?

Ugh.  Unless I am misreading the code we have the exact same problem
with /proc/self/mem.  Which uses a stricter form of the same test.

Same here.  ptrace_attach explicitly denies that case but that happens
outside of ptrace_may_attach to allow for the /proc usage.

Agreed.  Examining your self should always be valid.

I suspect this check get put in ptrace_may_attach, so we can always
read /proc/self/mem.

You may be right, but even if that is the case I think it is worth it.
The old checks were bizarre if not outright wrong.  And cause their
own share of weird cases when you start using things like namespaces.

The checks unify the two cases where we allow violating a tasks
privacy.  Which is an important case to get right, and unification
of permissions means it is easier to administer if you don't want
someone doing that.

/proc and ptrace have had a connection since at least 2.0 so this
is nothing new.  So if by using this on more than just /proc/<pid>/mem
I increase the frequency of usage and thus increase the frequency
of problem detection I think it is a good thing.

I think it is actually surprising no one noticed how bogus the
permissions on /proc/<pid>/fd/<fd#> have been, especially the people
concerned with security.

Agreed.  That does look a fishy. 

I also spotted an outright bug. put_task_struct does not work on a
NULL pointer. Duh.

Sorry I obviously didn't switch levels very well when auditing that
code.

I will send in a patch to clean up those bits.

I just tried rc5-mm1 and this. With this I can run java apps/applets again

Anyway, I think things are pretty much sorted out now so I'll try to do mm2
today (approx 12 hours hence).

I tested both the fuser command that had been crashing the earlier
kernels with Eric's /proc patches, and my "SGI internal software
management" application, on which I first saw these kernels fail.

With this 2.6.16-rc5-mm2-pre1 kernel, they both work - no more crash.

Good.

Well, I should have check my logs... There is a bunch of BUGs  
when I launch Gnome:

yup, that's a known-about warning for something which is harmless.  We're
still working out what to do about that.  The short-term solution is to
remove it.

I've tested this one and I can't crash it with eclipse like I could
plain old 2.6.16-rc5-mm1

I just tested this kernel and it builds and runs just fine. Can't
crash it with my eclipse test case.

With all the recent patches and proposed patches and discussions about
various approaches to fix this I've lost track.

What kernel with what patches applied and/or reverted would it make
the most sense for me to test now, in order to provide the most useful
testing?

So it looks like we have this tracked and fixed.  Andrew included my
fix in:
http://www.zip.com.au/~akpm/linux/patches/stuff/2.6.16-rc5-mm2-pre1.gz

So just confirming that the fixed actually worked would probably be
the biggest help.

The problem should be fixed unless there is something else that
triggers the horrible and mysterious kernel death.  So you are
getting the same results as everyone else.

2.6.16-rc5-mm2 works fine for me. Can't crash it with eclipse.

In a shell, do

Yeah, I did (in a plain text console) :

export DISPLAY=:0.0 ; sleep 3 ; eclipse

then switched to tty0 and got the following - written down by hand so
I left out some bits, hope I got the important bits - a few things may
have scrolled off the top of the screen though..
If needed this is completely repproducible, so in a pinch I could
reboot with a higher fb resolution + write down every little bit by
hand, but I hope the following is enough :

With this kernel something that causes the appended trace to appear happens on
my box (Asus L5D, 1 CPU, x86-64) 100% of the time during boot.

I'd be suspecting the /proc patches.   Can you send the .config please?

Yes this does feel like something got the reference counting of task structures
incorrect.  And I touched a lot of reference counting.  I will look into this
and see if I can find a culprit.

Thanks.

In the meantime it turned out the kernel booted with "init=/bin/bash" and
seemed to work.  Still when booted to eg. runlevel 2, it crashes while starting
services.

The config is attached.  If you need any more info/debugging for my part,
please let me know.

Greetings,
Rafael

For what it's worth, this is a NULL pointer dereference in the RCU
code.

Seems that the human-readible parts are printed at a differnet printk level
(well, _at_ a level), so they fell off. Not good.

Andrew and/or Paulus, see patch below.


Thanks,

Olof


---

It seems that the die() output is printk'd without any prink level,
so some distros will log the register dumps and the human readible
format differently.

(I.e. see http://test.kernel.org/24165/debug/console.log, which lacks
the KERN_ALERT parts)

Changing the die() output to include a level will likely confuse users
that currently rely on getting the output where they're getting it,
so instead remove it from the bad_page_fault() output.

And in an area where it is tougher than usual to blame the problem
on a broken use of RCU, as well.  ;-)

The "rcp" argument to __rcu_process_callbacks() is C00000076F303F08
and "rdp" is C00000076F303F08, or am I mis-remembering the POWER ABI?

My understanding was that printk lines without a level are considered
to be at KERN_ERR or so.  Is that wrong?

> Andrew and/or Paulus, see patch below.

It really seems strange to be *removing* printk level tags.  I'd like
to nack this until I understand why it will improve things.  At the
very least it needs a big fat comment so some janitor doesn't come
along and put the tags back in.

He's removing KERN_ALERT ... I guess it could get switched from 
KERN_ALERT to KERN_ERR, but ...

Either way, KERN_ALERT seems way too low to me. I object to getting
half the oops, and not the other half ;-)

Right. The new printk's were added recently, and I took the KERN_ALERT
level from the x86 code then without double-checking what die() uses. I
guess I could move the die() output over instead, or move them both to
KERN_ERR.

I just noticed x86 can now pass the log level around via
show_trace_log_lvl and show_stack_log_lvl. Something we might want to
add so we can KERN_EMERG the whole oops.

KERN_ALERT is two steps higher in priority (lower number) than
KERN_ERR.  Why on earth would we see KERN_ERR messages but not
KERN_ALERT messages?

In fact die() should probably be using KERN_EMERG.

Messages without a loglevel are by default logged at KERN_WARNING
level, one step lower in priority than KERN_ERR.

This all sounds to me like there is something wacky going on
somewhere, and we need to get to the bottom of it rather than just
remove printk tags.

Re: 2.6.16-rc5-mm1 -- strange load balancing problems

[Peter Williams]

I'm seeing some strange load balancing problems with this kernel.  I 
don't think that they're due to the smpnice patches as I've applied them 
on a standard 2.6.15-rc5 kernel and the problem doesn't happen there.

The problem is (as I say) quite strange and (for me) very reproducible. 
  I have two programs (aspin and gsmiley) which I use to produce CPU 
hard spinners for testing purposes.  What I'm finding is that when I 
start several copies of aspin load balancing goes as expected but when I 
launch several copies of gsmiley they all go to the one CPU and stick 
there like glue.  (The most obvious difference between the two programs 
is that aspin is just a command line tool while gsmiley is an X windows 
program that spins a simley face and reports its own assessment of the 
percentage of CPU it's getting.)  The machine that I've seen this 
problem is a hyper threading Pentium 4 and I suspect that it may be due 
to the SCHED_MC changes which overlap SCHED_SMT a bit.

I'm trying to test this on a non hyper threading machine but the machine 
has crashed (different kernel) while doing the build.  I'll resume this 
effort tomorrow but I thought that I should report the problem so that 
others could comment.

Peter
PS SCHED_MC was configured in but I'll try it without tomorrow and 
report the results.

Configuring SCHED_MC to "no" causes this problem to go away.

This problem does not appear to be present in 2.6.16-rc6-mm1.
