As far as I can tell, close-exec is not working correctly in 2.6.9
or 2.6.10-1.741_FC3smp.

The attached program generates a file /tmp/cl_foo.output
which has this data:


[greear@grok ~]$ more /tmp/cl_foo.output
total 5
lrwx------  1 greear greear 64 Jan 30 23:49 0 -> /dev/pts/3
l-wx------  1 greear greear 64 Jan 30 23:49 1 -> /tmp/cl_foo.output
l-wx------  1 greear greear 64 Jan 30 23:49 2 -> /tmp/cl_foo.output
lr-x------  1 greear greear 64 Jan 30 23:49 3 -> /etc/passwd
lr-x------  1 greear greear 64 Jan 30 23:49 4 -> /proc/7020/fd


I would not expect to see the /etc/passwd entry since I marked
it close-exec in the parent process before forking and running
the system() command.

Am I confused about things, or is this a real bug?

Thanks,
Ben
