0x12: Nuts-and-bolts Talk: Using eBPF for RDS filtering
by Jamal Hadi Salim 03 May '18

03 May '18

Tushar Dave will share his experiences in implementing Reliable Datagram Socket (RDS) filtering and firewalling. RDS sits on top of both TCP and IB, which presents a challenge: while TCP deals with skbs, IB/RDMA deals with scatterlists. Traditional firewalling with netfilter deals only with skbs. Tushar is looking for a unified solution for both TCP and IB. To this end he is adding/extending eBPF helpers to process messages that are in the form of struct scatterlist. https://www.netdevconf.org/0x12/session.html?using-ebpf-for-rds-filtering Reminder: Early bird registration expires on June 1st. cheers, jamal

0x12: Moonshot Talk: BBRx: Extending BBR for Customized TCP Performance
by Jamal Hadi Salim 30 Apr '18

30 Apr '18

The future of optimal TCP involves robots! Jae Won Chung et al will discuss an extension to BBR they call BBRx which is loosely coupled to machine learning. They will describe how they study TCP path attributes in user space at runtime to find an optimal throughput-delay operating point. The results are then fed back to the kernel to tweak it. Performance of BBRx is evaluated in both LTE mobile as well as telco wireline environments and compared with classical CUBIC and BBR. cheers, jamal

0x12: First Hands-on! IPsec/IKE tutorial/lab
by Jamal Hadi Salim 26 Apr '18

26 Apr '18

If you have ever been intimated by IPsec or always wondered what IPsec is and/or how IPsec datapath works in the kernel or how IPsec control path works in user space then this tutorial is for you. Sowmini Varadhan and Paul Wouters will guide you through the theory then the operations for two hours! You will be walked through the steps for setting up IKE/IPsec on VMs on your laptops. A number of other VMs will be made available as targets to connect-to for the different IKE scenarios via Libreswan. These scenarios include some commonly encountered roadblocks that will be used to teach IPsec trouble-shooting issues. More details: https://www.netdevconf.org/0x12/session.html?ipsecike-tutoriallab cheers, jamal

0x12: Location Selected!
by Jamal Hadi Salim 24 Apr '18

24 Apr '18

We are pleased to announce that we have selected our conference location. Netdev 0x12 conference will be held at the Hyatt Regency, Montreal. The Hyatt is located at the Complexe Desjardins. Address: 1255 Jeanne-Mance St, Montreal, QC H5B 1E5 url: https://montreal.regency.hyatt.com/en/hotel/home.html Montreal is a fantastic place to visit in the summer; so many things to see and do. So come before the conference or stay after the conference ;-> We are going to be putting a lot more info, but here is a starting point: https://www.netdevconf.org/0x12/montreal.html This time we are not going to block a bunch of rooms at the conference hotel. There are so many options in that neighborhood for hotels and short term rentals. We will be providing a big list of options and will assist folks who need our help. If you have any questions that you feel other people may be interested in regarding this topic, please post on this list (people(a)netdevconf.org) if you want to only reach the organizers post to info(a)netdevconf.org cheers, jamal

0x12: First Nuts-n-bolts talk! Subscriber Billing System Over Commodity Hardware
by Jamal Hadi Salim 23 Apr '18

23 Apr '18

Do you know how your data plan gets billed by them telcos? Yes, them. What about a shared (family) plan? How can one use existing kernel features to build a robust billing and service platform? Vikram Siwach will describe the challenges faced in getting Linux on commodity hardware[1] and kernel changes made to make all this work. https://www.netdevconf.org/0x12/session.html?subscriber-billing-system-over… cheers, jamal [1] it is called commodity because telcos like to buy these boxes from big vendors. The box was so commodity it had a Mellanox connectx3 on it!

0x12: First Moonshot talk! Kernel TLS handshakes for HTTPS DDoS mitigation
by Jamal Hadi Salim 21 Apr '18

21 Apr '18

Our first accepted talk! KTLS focuses mostly on zero-copy data transfers and only offloads encryption and decryption and ignores TLS handshakes. However, TLS handshakes are susceptible to DDos attacks which are very effective at depleting resources. Alexander Krizhanosky will describe Offloading Kernel TLS handshakes to counter HTTPS DDoS mitigation https://www.netdevconf.org/0x12/news.html?talk-alexander-krizhanosky-kernel… The session submission is still open! Don't procrastinate! cheers, jamal
