[Kernel-packages] [Bug 1265841] Re: kernel BUG at /build/buildd/linux-3.11.0/fs/buffer.c:1268!; RIP: 0010:[ffffffff816e3efd] [ffffffff816e3efd] check_irqs_on.part.11+0x4/0x6
I don't know, the cause is apparently that IRQs are disabled, but I
don't know whether that's considered an error. The aesni_intel module is
needed to trigger the bug, but that doesn't imply that it contains the
bug. It's possible that ecryptfs is using it wrong, or that the fallback
code (which is used when aesni_intel is not available) happens to
contain something that avoids the bug. Since ecryptfs is the module that
binds all these other modules together, I thought that was the right
place to ask.
The ecryptfs mailing list doesn't seem very active though, is it normal
that this takes so long? Should I send it directly to one of the
maintainers?

Bug description:
This only happens when aesni_intel is loaded.
In my attempts to find an easy way to reproduce this bug:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1265684
I actually found a very simple way to trigger a bug that is similar but not
identical. I suspect that both bugs have the same cause: something in the
kernel is disabling IRQs and the ext4 code will crash when this happens. The
stack trace for this bug is different from the other one. This one appears to
be less severe, the system is still usable after the crash, only the process
that caused the crash will hang (uninterruptible sleep). This bug is 100%
reproducible on both Ubuntu 13.10 with kernel 3.11.0 and Arch Linux with kernel
3.12.6.
The steps to reproduce the bug are based on this:
http://www.spinics.net/lists/linux-ext4/msg38949.html
* Set up an ecryptfs 'Private' folder in your home directory.
* In that directory, create a file called 'crashme.c' with the following code
in it:
#include assert.h
int main() { assert(0); }
* Compile the program:
gcc -Wall crashme.c -o crashme
* Change the core dump pattern so core dumps are saved in the current
directory:
echo coredump-%p | sudo tee /proc/sys/kernel/core_pattern
* Enable core dumps:
ulimit -c unlimited
* Make sure that you have a second terminal open to run dmesg, because you
may not be able to do so later.
* Run 'crashme' - this will hang and trigger the bug:
./crashme

I can do it if you really want, but I think I already know the result.
According to this:
http://www.phoronix.com/scan.php?page=news_itempx=MTM2OTg
... ecryptfs AES-NI support was only added in kernel 3.10. Both quantal and
raring use older kernels, so they will not load the aesni_intel module and
won't be affected, just like 12.04.
I will try to install some older kernels on saucy, I should be able to
find out if the issue started with kernel 3.10 or later.

The tests I did confirmed what I suspected:

* kernel 3.11 is affected (if aesni_intel is loaded)
* kernel 3.10 is affected (if aesni_intel is loaded)

matter whether it's loaded)

[Kernel-packages] [Bug 1265841] [NEW] Kernel crash in ext4/ecryptfs after core dump in encrypted folder
Public bug reported:
In my attempts to find an easy way to reproduce this bug:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1265684
... I actually found a very simple way to trigger a bug that is similar but not
identical. I suspect that both bugs have the same cause: something in the

The stack trace for this bug is different from the other one. This one
appears to be less severe, the system is still usable after the crash,
only the process that caused the crash will hang (uninterruptible
sleep).
This bug is 100% reproducible on both Ubuntu 13.10 with kernel 3.11.0

The steps to reproduce the bug are based on this:

* Set up an ecryptfs 'Private' folder in your home directory.
* In that directory, create a file called 'crashme.c' with the following

* Compile the program:

* Change the core dump pattern so core dumps are saved in the current

* Enable core dumps:
ulimit -c unlimited
* Make sure that you have a second terminal open to run dmesg, because
you may not be able to do so later.
* Run 'crashme' - this will hang and trigger the bug:

Kernel crash in ext4/ecryptfs after core dump in encrypted folder
Status in “linux” package in Ubuntu:
New
Bug description:
In my attempts to find an easy way to reproduce this bug:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1265684
... I actually found a very simple way to trigger a bug that is similar but
not identical. I suspect that both bugs have the same cause: something in the
kernel is disabling IRQs and the ext4 code will crash when this happens.
The stack trace for this bug is different from the other one. This one
appears to be less severe, the system is still usable after the crash,
only the process that caused the crash will hang (uninterruptible
sleep).
This bug is 100% reproducible on both Ubuntu 13.10 with kernel 3.11.0
and Arch Linux with kernel 3.12.6.
STEPS TO REPRODUCE
--
The steps to reproduce the bug are based on this:
http://www.spinics.net/lists/linux-ext4/msg38949.html
* Set up an ecryptfs 'Private' folder in your home directory.
* In that directory, create a file called 'crashme.c' with the
following code in it:
#include assert.h
int main() { assert(0); }
* Compile the program:
gcc -Wall crashme.c
[Kernel-packages] [Bug 1265841] Re: Kernel crash in ext4/ecryptfs after core dump in encrypted folder
Blacklisting the aesni_intel module appears to fix this crash (but maybe
not the other one, I don't know). I will try to get the latest kernel
and do more testing.

* Make sure that you have a second terminal open to run dmesg, because you
may not be able to do so later.

My attempts to reproduce the bug on purpose have failed so far, bug I did find a very simple way to reproduce a similar bug that may have the same cause: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1265841 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1265684 Title: [Gigabyte Z87X-D3H] Kernel crash, appears related to ext4 and ecryptfs Status in “linux” package in Ubuntu: Incomplete Bug description: This problem is very similar, but happened with a different kernel (I was using Arch Linux): I am using firefox, I have encrypted my firefox profile folder with ecryptfs, and the underlying file system is ext4. While I was using firefox, the program became frozen and could not be killed. The 'htop' utility indicated that firefox and some other processes had status 'D', i.e. 'uninterruptible sleep'. My graphical session was still functional, and I could open a terminal and run 'dmesg', but any attempt to save it to the hard disk would freeze bash (uninterruptible sleep, just like firefox). I was able to save the output on a different physical hard disk (i.e. not the one that was used by firefox and ecrypt). After that I tried to reboot, but this caused the kernel to lock up and required a hard reset. So far I have not been able to reproduce this issue, so I can only give a stack trace for Linux 3.12.6 (from Arch Linux): [42210.127535] [ cut here ] [42210.127540] kernel BUG at fs/buffer.c:1278!

Oh, and for what it's worth, I have run memtest86+ and mprime to
eliminate the most obvious hardware problems, and both tests didn't find

In my attempts to find an easy way to reproduce this bug:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1265684
I actually found a very simple way to trigger a bug that is similar but not
identical. I suspect that both bugs have the same cause: something in the
kernel is disabling IRQs and the ext4 code will crash when this happens. The
stack trace for this bug is different from the other one. This one appears to
be less severe, the system is still usable after the crash, only the process
that caused the crash will hang (uninterruptible sleep). This bug is 100%
reproducible on both Ubuntu 13.10 with kernel 3.11.0 and Arch Linux with kernel
3.12.6.
The steps to reproduce the bug are based on this:
http://www.spinics.net/lists/linux-ext4/msg38949.html
* Set up an ecryptfs 'Private' folder in your home directory.
* In that directory, create a file called 'crashme.c' with the following code
in it:
#include assert.h
int main() { assert(0); }
* Compile the program:
gcc -Wall crashme.c -o crashme
* Change the core dump pattern so core dumps are saved in the current
directory:
echo coredump-%p | sudo tee /proc/sys/kernel/core_pattern
* Enable core dumps:
ulimit -c unlimited
* Make sure that you have a second terminal open to run dmesg, because you
may not be able to do so later.
* Run 'crashme' - this will hang and trigger the bug:
./crashme

I don't know, this is a new computer. But on my older computer I had an
identical setup that I have used for months with kernels 3.9 up to 3.12
with no issues at all. On the new computer it happened twice in just one
week. So I suspect it is hardware-related somehow.

I tried to install 12.04 but I ran into some issues. The installer seems
buggy, it used the wrong EFI partition and failed to install grub, but I
was still able to boot it by re-using the 13.10 grub install, and I
think the install is okay. Unfortunately 12.04 doesn't seem to have
drivers for my ethernet controller, so I couldn't connect to the
internet and update (this was already the case with the live as well). I
did the test anyway based on the packages that came with the CD (that
was the very first 12.04 I believe, not 12.04.2).
It turns out ecryptfs on 12.04 does not load the aesni_intel module (I
suppose it didn't support it yet). Because of that it does not crash. I
tried loading the aesni_intel module manually, but this does not seem to
make a difference (ecryptfs probably doesn't use it).
So technically this is a regression from 12.04, but only because 12.04
didn't use aesni_intel yet.
My previous installation *did* use aesni_intel without problems (but
with different hardware).

[Kernel-packages] [Bug 1265684] [NEW] Kernel crash, appears related to ext4 and ecryptfs
Public bug reported: As requested by Christopher M. Penalver, I'm submitting a new bug report for the problem I mentioned here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1258313 This problem is very similar, but happened with a different kernel (I was using Arch Linux): I am using firefox, I have encrypted my firefox profile folder with ecryptfs, and the underlying file system is ext4. While I was using firefox, the program became frozen and could not be killed. The 'htop' utility indicated that firefox and some other processes had status 'D', i.e. 'uninterruptible sleep'. My graphical session was still functional, and I could open a terminal and run 'dmesg', but any attempt to save it to the hard disk would freeze bash (uninterruptible sleep, just like firefox). I was able to save the output on a different physical hard disk (i.e. not the one that was used by firefox and ecrypt). After that I tried to reboot, but this caused the kernel to lock up and required a hard reset. So far I have not been able to reproduce this issue, so I can only give a stack trace for Linux 3.12.6 (from Arch Linux): [42210.127535] [ cut here ] [42210.127540] kernel BUG at fs/buffer.c:1278!

[Kernel-packages] [Bug 1265684] Re: Kernel crash, appears related to ext4 and ecryptfs
No, I meant I have no idea how to reproduce it at all, either on Arch or Ubuntu. It happened for the first time a few days ago, and again 5 minutes ago (also on Arch, because my Ubuntu install isn't using ecryptfs at the moment). I will try to set up ecryptfs on my Ubuntu install and try to trigger the bug. I've also moved my firefox profile outside ecryptfs on my Arch install to see if this is really related to ecryptfs or just firefox. Here's the stack trace from the new crash. It's nearly identical: firefox, ecryptfs and ext4. The symptoms were exactly the same except that this time firefox was killed instead of frozen (but other applications would still freeze when writing to the disk).

[Kernel-packages] [Bug 1258313] Re: Kernel crashes with error in fs/buffer.c:1268
I had a crash with a stack trace that looks VERY similar, but this was on Arch Linux with kernel 3.12.6, with very different hardware. I am running firefox with the .mozilla folder in ecryptfs on an ext4 hard disk, and the crash happened while I was using firefox. Is that what you are doing as well? The strange thing is, I have been doing the same for months on a different computer with no issues (also with kernel 3.11). ** Attachment added: Trace for very similar bug with kernel 3.12.6 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1258313/+attachment/3938039/+files/crash-ecryptfs-ext4-firefox.txt -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1258313 Title: Kernel crashes with error in fs/buffer.c:1268 Status in “linux” package in Ubuntu: Incomplete Bug description: After the upgrade to 3.11.0-15, the kernel crashes with the following message: Dec 5 22:05:02 excelsior kernel: [22046.717322] kernel BUG at /build/buildd/linux-3.11.0/fs/buffer.c:1268!
