[1.] One line summary of the problem:
Core dump in ecryptfs directory on ext4 crashes kernel if aesni_intel is
used.
[2.] Full description of the problem/report:
This bug happens when a process tries to do a core dump in a directory
that is encrypted with ecryptfs on top of a ext4 file system. It only
happens when the aesni_intel module is loaded, and only with versions of
ecryptfs that can make use of aesni_intel (requires kernel 3.10 or
later). The cause of the crash seems to be that something in the kernel
is disabling IRQs and the ext4 code will crash when this happens.
It seems that a similar bug has been reported before:
http://www.spinics.net/lists/linux-ext4/msg38949.html
Steps to reproduce:
* 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

Launchpad bug report:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1265841
The ext4 partition is mounted as:
/dev/sdb2 on / type ext4 (rw,errors=remount-ro)
Ecryptfs is mounted as:
/home/maarten/.Private on /home/maarten/Private type ecryptfs
(ecryptfs_check_dev_ruid,ecryptfs_cipher=aes,ecryptfs_key_bytes=16,ecryptfs_unlink_sigs,ecryptfs_sig=*****,ecryptfs_fnek_sig=*****)
Possibly related bug:
http://www.spinics.net/lists/linux-ext4/msg38949.html
Temporary workaround: blacklist the aesni_intel module.
Core dump in ecryptfs directory on ext4 crashes kernel if aesni_intel is
used.
[2.] Full description of the problem/report:
This bug happens when a process tries to do a core dump in a directory
that is encrypted with ecryptfs on top of a ext4 file system. It only
happens when the aesni_intel module is loaded, and only with versions of
ecryptfs that can make use of aesni_intel (requires kernel 3.10 or
later). The cause of the crash seems to be that something in the kernel
is disabling IRQs and the ext4 code will crash when this happens.
It seems that a similar bug has been reported before:
http://www.spinics.net/lists/linux-ext4/msg38949.html
Steps to reproduce:
* 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
