Linux Kernel Developers' Netconf

The first rule of Netconf is: You do not talk about Netconf. The second rule of Netconf is: You do not talk about Netconf.

Netconf is a Linux community conference, by-invitation-only, running since 2004. The agenda has a clear focus on kernel level networking. Attendees are the main maintainers and developers of the Linux networking subsystem.

Due to the distributed nature of the Network subsystem development, contributors to the stack are located in different corners of the globe and coordinate security and bug fixes as well as maintanance and new features via email.

Netconf is intended to be a face to face working meetup to compliment those email exchanges. Problematic unresolved issues are hashed out and bold new ideas are discussed.
