Kernel Programming 101 – Creating your own Linux Kernel Module
Have you ever wanted to write your own kernel module? This multi-part blog post will talk about creating your first kernel module, using the proc file system, gathering and updating statistics and will cover topics such as your kernel as a menu items to menuconfig, setting defaults in the kernel config, registering network callbacks for specific types of packets taking Cisco CDP as an example and some tips-tricks in writing and debugging kernel code. A lot of my own learning has been through blogs and experiments. One source that is really great and does summarize a lot of what my blog will talk about and more is TLDP (The Linux Documentation Project).
When there's need to perform operations without cpu cycles wastage and/or reduce user space copy overheads, kernel programming suits the bill. Taking networking and linux networking stack as Continue reading
The Simple Leads to the Spectacular
Steve Kerr, head coach of the record setting Golden State Warriors (my local Bay Area NBA basketball team), has this to say about what the team needs to do to get back on track (paraphrased):
What we have to get back to is simple, simple, simple. That's good enough. The simple leads to the spectacular. You can't try the spectacular without doing the simple first. Make the simple pass. Our guys are trying to make the spectacular plays when we just have to make the easy ones. If we don't get that cleaned up we're in big trouble.
If you play the software game, doesn't this resonate somewhere deep down in your git repository?
If you don't like basketball or despise sports metaphors this is a good place to stop reading. The idea that "The simple leads to the spectacular" is probably the best TLDR of Keep it Simple Stupid I've ever heard.
Software development is fundamentally a team sport. It usually takes a while for this lesson to pound itself into the typical lone wolf developer brain. After experiencing a stack of failed projects I know it took an embarrassingly long time for me to Continue reading

ASERT was initially alerted about an emerging threat called AlphaLeon by Deep & Dark Web intelligence provider Flashpoint in August 2015. It caught and kept our interest because it sounded like it could be a new “banker” malware family.

How often do you find yourself scratching your head, trying to remember a command that you knew by heart but just can’t remember when you need it most? It happens for me quite often. Probably because I am aging or may be there is too much stuff in my brain attic. But I found a solution […]Don’t Touch My Mustache, Aruba!
It’s been a year since Aruba Networks became Aruba, a Hewlett-Packard Enterprise Company. It’s been an interesting ride for everyone involved so far. There’s been some integration between the HPE Networking division and the Aruba teams. There’s been presentations and messaging and lots of other fun stuff. But it all really comes down to the policy of non-interference.
Don’t Tread On Me
HPE has done an admirable job of keeping their hands off of Aruba. It sounds almost comical. How many companies have acquired a new piece and then done everything possible to integrate it into their existing core business? How many products have had their identity obliterated to fit in with the existing model number structure?
Aruba isn’t just a survivor. It’s come out of the other side of this acquisition healthy and happy and with a bigger piece of the pie. Dominick Orr didn’t just get to keep his company. Instead, he got all of HPE’s networking division in the deal! That works out very well for them. It allows Aruba to help integrate the HPE networking portfolio into their existing product lines.
Aruba had a switching portfolio before the acquisition. But that was just an afterthought. It Continue reading
