As someone who has gone through the ipfwadm -> ipchains -> iptables history, I would generally be pretty meh about another firewalling change. But, I have high hopes that it'll give me the ability to do reasonable traffic shaping in Linux.<p>I once set up a FreeBSD box to do shaping for an ISP's entire DSL customer base, and it was a couple commands and worked brilliantly! By contrast, I've dabbled with Linux shaping for ~2 decades, and the best I've gotten is one recipe that works well for one limited use case. Maybe it's just me, but I've never been able to make it do my bidding, despite several occasions sitting down and giving it the old college try.<p>For other kernel paths, I'm really interested in using it to monitor for file modifications in the way that inotify is not very good. And I often resort to strace to figure out low level what is going on, it might be really good for that too.<p>Looks like an interesting book!
I've been a fan of dtrace for a long time and so I've been meaning to learn BPF to get similar functionality native to the linux kernel. I may pick this book up.
It's an advertisement for a book. Cilium is on there and that's a name I associate with blogverts.<p>There are eleven exclamation marks on that page.<p>BPF is the new paradigm for synergistic application of strategic opportunities in the use of acronyms.
Thanks for sharing Jessie! I am definitely going to order this book :-)<p>EDIT:
Why did I get down voted? I am not affiliated with this book, the authors of the book, or the OP in anyway. It just so happens that I will find this book very useful, so I thanked the OP for sharing.<p>It is sad we live in a world where there is so much manipulation that we are suspicious of each other's sincerity. I guess I understand where the downvoter was coming from :-(
