HI,
1. ¿What's the real value (in terms of security) of the random PIDs feature?
According to this book
http://books.google.es/books?id=gqKwaHmXp4YC&pg=PA50&lpg=PA50&dq=random+pids+security&source=bl&ots=jimAeOQK2Q&sig=WrsBiMAxU-lUCM3pdCjtIYfmiIo&hl=es&ei=OwVoS4nwGMeOjAek5ZCvCQ&sa=X&oi=book_result&ct=result&resnum=9&ved=0CCsQ6AEwCA#v=onepage&q=random%20pids%20security&f=false
I understand that the random PIDs wil be a good security measure against
some exploits (books says "race conditions"). OpenBSD folks (focused on
security) have the random PIDs by defaul, so
¿why Freebsd don't use it by default?
2. ¿What will be a real secure value for sysctl parameter? I mean
'kern.randompid' isn't a boolean, but a large number which determines
the numeric range to generate de random PIDs. ¿1000, 10000, 100000?
Thanks in advance for aclarations.
PD. I've real this old post
http://marc.info/?l=freebsd-security&m=99495048923300&w=2. Interesting.

I must not fear. Fear is the mind-killer. Fear is the little-death that
brings total obliteration. I will face my fear. I will permit it to pass
over me and through me. And when it has gone past I will turn the inner
eye to see its path. Where the fear has gone there will be nothing. Only
I will remain.
