Uh, not sure what's up with lkml.org -- I see some G+ +1 buttons but no actual text, in both Firefox and Chrome. Presumably the article is this: https://lwn.net/Articles/637658/ in which case it sounds awesome!

Thanks, we updated the link.

This is excellent.

Anyone who's ever faced the daunting task of bolting TCP on top of custom datagram protocol can certainly confirm how useful a library like this is.

It will be interesting to see how this evolves; hopefully it will make it easier to build a userland TCP/IP stack, and maybe even to make it easier to ship a new transport protocol (this might make it easier to push for HTTP over SCTP instead of TCP, which makes far more sense, really). Also this will be nice if it allows userland applications to utilize ICMP (traceroute/nmap would no longer be nerfed without root access). NUSE alone should be incredibly handy.

Lennart Poettering would do well to pay attention to people like this, continuing to honor the POSIX way.

As someone who's currently facing that daunting task myself, may I ask what you ended up doing? Did you have to roll your own reliable stream-oriented protocol?

I have to credit this blog for much of the material I've absorbed over the years, it's been fantastic how much I've learned here.

I've always managed to learn something new from articles, all this to say that today is different... I really do not understand this library at all.

Could someone explain me different possible uses for this library? What would be the uses of this out of the box?
