You’ve probably heard by now of the big launch of Cisco’s new 802.11ax (neé Wi-Fi 6) portfolio of devices. Cisco did a special roundtable with a group of influencers from the community called Just The Tech. Here’s a video from that event covering the APs that were released, the 9120:
Fred always does a great job of explaining the technical bits behind the APs. But one thing that caught my eye here is the name of the AP – Catalyst. Cisco has been using Aironet for their AP line since they purchased Aironet Wireless Communications back in 1999. The name was practically synonymous with wireless technologies for many people in the industry that worked exclusively with Cisco technologies.
So, is the name change something we should be concerned about?
Cisco moving toward a unified naming convention for their edge solutions makes a lot of sense. Ten years ago, wireless was still primarily 802.11g-based with 802.11n still a few months away from being proposed and ratified. Connectivity hadn’t quite yet reached the ubiquitous levels of wireless that we see today. The iPhone was only about to be on its third Continue reading

List of technical features that matter

It is unlikely we can tell you anything new about the extended Berkeley Packet Filter, eBPF for short, if you've read all the great man pages, docs, guides, and some of our blogs out there.
But we can tell you a war story, and who doesn't like those? This one is about how eBPF lost its ability to count for a while1.
They say in our Austin, Texas office that all good stories start with "y'all ain't gonna believe this… tale." This one though, starts with a post to Linux netdev mailing list from Marek Majkowski after what I heard was a long night:
Marek's findings were quite shocking - if you subtract two 64-bit timestamps in eBPF, the result is garbage. But only when running as an unprivileged user. From root all works fine. Huh.
If you've seen Marek's presentation from the Netdev 0x13 conference, you know that we are using BPF socket filters as one of the defenses against simple, volumetric DoS attacks. So potentially getting your packet count wrong could be a Bad Thing™, and affect legitimate traffic.
Let's try to reproduce this bug with Continue reading
