Hi, We are pleased to announce a new round in the Netfilter workshop series. This year this event will take place from October 20 to October 21, 2022. The event will be held at Zevenet [1] facilities in Mairena del Aljarafe, Seville, Spain. The Netfilter Workshop (NFWS) is the premier event organized by and for the Netfilter community. During the workshop days, Linux network and Netfilter developers meet and discuss the status of ongoing developments related to Netfilter and plans for the future. Attendance requires an invitation. Linux network developers with significant contributions to any of the Netfilter subsystems and users with interesting use cases and open problems are also welcome. We have traditionally held a space for sister projects that build on the Netfilter infrastructure such as the Linux Virtual Server project. You can send us a proposal to coreteam@xxxxxxxxxxxxx in a very light format: title and quick abstract (no more than 500 words!), as well as the estimated time. Not later than September 30. We are also looking for sponsors to cover expenses, if you think you can help us raise funds to hold the workshop, please contact us at coreteam@xxxxxxxxxxxxx and we will be glad to send you our sponsorship policy. Join us. [1] https://www.zevenet.com P.S: This edition will celebrate 24 years since this project began in the fall of 1998.
