Yes, you are right. It was my fault. I should have send my mail to both kernel and glibc list.
I just want to intercept open call. That's all. I don't care much if I must do a kernel module or I use PRELOAD. Probably is better to use LD_PRELOAD.
Thank you all for your kindly help! You are great! All of you! Thanks!
