When you run the program in attachment, *even as an ordinary user*, the kernel
panic. Tested kernel is a 2.6.11.7 vanilla with alleged .config. Tested with
similar configuration on both a qemu machine and a real one (only fs changes).
The code is taken by a program of mine, and slightly simplified, but don't
trust comments.
Keywords: ptrace, (p)thread
Kernel version: 2.6.11.7 vanilla
Output:
When the program is run, the kernel triggers a BUG(), and the following one is
repeated quite a lot of times, with increasing Call Trace:
