Package: hurd
Version: 20000803
If you perform the following steps, the Hurd will either crash
or reboot:
root@orson:~# touch test
root@orson:~# ls -l
total 0
-rw-r--r-- 1 root root 0 Sep 23 20:48 test
root@orson:~# chmod a+rx test
root@orson:~# ls -l
total 0
-rwxr-xr-x 1 root root 0 Sep 23 20:48 test
root@orson:~# ./test
[ ... hang ... ] (Or sometimes reboot).
Under Linux, the behavior is more benign:
bfulgham@hopper:~# touch test
bfulgham@hopper:~# ls -l test
-rw-r--r-- 1 bfulgham bfulgham 0 Sep 23 21:56 test
bfulgham@hopper:~# chmod a+rx test
bfulgham@hopper:~# ls -l test
-rwxr-xr-x 1 bfulgham bfulgham 0 Sep 23 21:56 test
bfulgham@hopper:~# ./test
bfulgham@hopper:~#
Hurd behavior should be modified to safely handle this condition.
Thanks!
