[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 [3.] Keywords (i.e., modules, networking, kernel): [4.] Kernel version (from /proc/version): Kernel 3.10.0, 3.11.0, 3.12.6, 3.13.0-rc6 are all affected. Kernel 3.9.0 is NOT affected.
