kernel oops log

How to reproduce:
$ mkdir {lower,upper,work,overlay}
$ uname > lower/uname
# mount overlay -t overlay -o lowerdir=lower,upperdir=upper,workdir=work overlay
$ # edit overlay/uname

Results:
Kernel oops, screen freezes.

I've debugged this a bit, the failure occurs on an atomic_inc on root,

Commit 4bacc9c9234c7c8eec44f5ed4e960d9f96fa0f01 ("overlayfs: Make f_path
always point to the overlay and f_inode to the underlay") resulted in an
issue when using a combination of btrfs and overlayfs.  This is
noticeable when doing a fsync() on a file in a chroot with overlayfs on
top of btrfs; we hit a kernel oops in btrfs_sync_file() on
atomic_inc(>log_batch) because root is NULL.

I've debugged this further and found that in btrfs_sync_file():

struct inode *inode = d_inode(dentry);

does not return the inode I expected when using the stacked overlay fs,
where as:

struct inode *inode = file_inode(file);

does.

However, I'm not well at all well versed in btrfs, so I am not confident
this is a actually correct.  Any comments?

Given that this is stuck waiting for upstream to figure out a way
forward, which looks unlikely at the moment, plus we have a suitable
workaround, I'm going to mark this as Won't Fix.

[Kernel-packages] [Bug 1532145] Re: Kernel Panic wrt btrfs while sbuild/schroot

2016-02-16 Thread Colin Ian King
I suggest a workaround for the moment, using aufs as the overlay to see
if this helps.

Modify the chroot config and set the union-type to aufs:

union-type=aufs

you may see an error like:

"aufs au_xino_create:778:mount[3600]: xino doesn't support
/tmp/.aufs.xino(btrfs)"

this is caused by the fact that btrfs cannot store aufs xino files.
aufs tries to store these files alongside the rw layer. If that fails,
it tries to store them in /tmp/.aufs.xino, however, if this is btrfs it
will fail. So the workaround for that is to mount /tmp as something
other than btrfs,  e.g. tmpfs

2016-02-15 Thread Colin Ian King
bisected: 4bacc9c9234c7c8eec44f5ed4e960d9f96fa0f01 is the first bad
commit


commit 4bacc9c9234c7c8eec44f5ed4e960d9f96fa0f01
Author: David Howells 
Date:   Thu Jun 18 14:32:31 2015 +0100

overlayfs: Make f_path always point to the overlay and f_inode to the 
underlay

Make file->f_path always point to the overlay dentry so that the path in
/proc/pid/fd is correct and to ensure that label-based LSMs have access to 
the
overlay as well as the underlay (path-based LSMs probably don't need it).

Using my union testsuite to set things up, before the patch I see:

[root@andromeda union-testsuite]# bash 5 /a/foo107
[root@andromeda union-testsuite]# stat /mnt/a/foo107
...
Device: 23h/35d Inode: 13381   Links: 1
...
[root@andromeda union-testsuite]# stat -L /proc/$$/fd/5
...
Device: 23h/35d Inode: 13381   Links: 1
...

After the patch:

[root@andromeda union-testsuite]# bash 5 /mnt/a/foo107
[root@andromeda union-testsuite]# stat /mnt/a/foo107
...
Device: 23h/35d Inode: 40346   Links: 1
...
[root@andromeda union-testsuite]# stat -L /proc/$$/fd/5
...
Device: 23h/35d Inode: 40346   Links: 1
...

Note the change in where /proc/$$/fd/5 points to in the ls command.  It was
pointing to /a/foo107 (which doesn't exist) and now points to /mnt/a/foo107
(which is correct).

The inode accessed, however, is the lower layer.  The union layer is on 
device
25h/37d and the upper layer on 24h/36d.

3.17 + a forward port of ubuntu utopic overlay fs - works fine, 3.18
with overlayfs has the problem, so now I've got a bisectable range to
work on.

[Kernel-packages] [Bug 1532145] Re: Kernel Panic wrt btrfs while sbuild/schroot

2016-02-10 Thread Colin Ian King
OK, bisectable, 3.13 good, 3.19 bad. Test is simple, build the following
and run in a chroot on a btrfs system and it will trip the same bug.

#define _GNU_SOURCE
#include 
#include 
#include 
#include 

int main(void)
{
char buffer[1024] = { 0 };
int fd;

fd = open("test", O_CREAT | O_RDWR, 0777);
if (fd < 0)
return 1;

(void)write(fd, buffer, sizeof(buffer));
fsync(fd);
(void)close(fd);

return 0;
}

Bug description:
  I'm running ubuntu Wily amd64 on a MSI Ghost Pro laptop.

  I'm running btrfs on top of a bcached dmraid setup(intel software
  raid0).

  I can't use sbuild, cause it crashes.

  I tried to use  a schroot env, and when updating it I got it to crash
  also.

  All the keyboard/mouse/X11 are stalled, but I could ssh to it.
  Trying to restart lightdm service didn't help.

  I've got a kernel trace in the dmesg:

2016-01-19 Thread Kick In
Same bug that I already had with another laptop, it seems to be related
to overlay and btrfs:

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1496438

Happens also on coreos:
https://github.com/coreos/rkt/issues/1498

Title:
  Kernel Panic wrt btrfs while sbuild/schroot

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I'm running ubuntu Wily amd64 on a MSI Ghost Pro laptop.

  I'm running btrfs on top of a bcached dmraid setup(intel software
  raid0).

  I can't use sbuild, cause it crashes.

  I tried to use  a schroot env, and when updating it I got it to crash
  also.

  All the keyboard/mouse/X11 are stalled, but I could ssh to it.
  Trying to restart lightdm service didn't help.

  I've got a kernel trace in the dmesg:

[Kernel-packages] [Bug 1532145] Re: Kernel Panic wrt btrfs while sbuild/schroot

2016-01-19 Thread Joseph Salisbury
Did this issue start happening after an update/upgrade? Was there a
kernel version where you were not having this particular problem? This
will help determine if the problem you are seeing is the result of a
regression, and when this regression was introduced.   If this is a
regression, we can perform a kernel bisect to identify the commit that
introduced the problem.

Title:
  Kernel Panic wrt btrfs while sbuild/schroot

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I'm running ubuntu Wily amd64 on a MSI Ghost Pro laptop.

  I'm running btrfs on top of a bcached dmraid setup(intel software
  raid0).

  I can't use sbuild, cause it crashes.

  I tried to use  a schroot env, and when updating it I got it to crash
  also.

  All the keyboard/mouse/X11 are stalled, but I could ssh to it.
  Trying to restart lightdm service didn't help.

  I've got a kernel trace in the dmesg:

2016-01-11 Thread Kick In
I tried with the upstream v4.4-wily kernel.

kick@kick-gs60:~/work/merges/freeipmi$ uname -a
Linux kick-gs60 4.4.0-040400-generic #201601101930 SMP Mon Jan 11 00:32:41 UTC

I couldn't re-use my previous schroot (couldn't mount with overlayfs).
I've created a new one with --type=btrfs-snapshot.

My latop didn't freeze, but I still got traces in the syslog:

[Kernel-packages] [Bug 1532145] Re: Kernel Panic wrt btrfs while sbuild/schroot

2016-01-08 Thread Joseph Salisbury
Did this issue start happening after an update/upgrade?  Was there a
prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.4 kernel[0].

If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as
"Confirmed".


Thanks in advance.
