Solo BumbleBee helps make Linux eBPF programming less difficult

In 1992, the Berkeley Packet Filter (BPF) was launched in Unix circles as a new, enhanced community packet filter. Pleasant, but not that huge a deal. Then, in 2014, it was altered and brought into the Linux kernel as extended BPF (eBPF). Once again, that was alright. Just alright. Quickly thereafter however, builders started off applying it to run consumer-place code within a virtual device (VM) on the Linux kernel.  And, then it was a enormous offer. As Netflix computer system efficiency pro Brendan Gregg mentioned, with eBPF, “superpowers have ultimately appear to Linux.”

What superpowers? eBPF presents you the electricity to run applications in the Linux kernel without having altering the kernel resource code or introducing added modules. In influence, it acts as a light-weight (VM) inside the Linux kernel space. There, applications that can run in eBPF run significantly speedier, even though having gain of kernel features unavailable to other higher-amount Linux packages.

Of class, running applications that near to the kernel even with eBPF isn’t really uncomplicated. That is wherever, an application networking company, comes in with its new open up-supply challenge, BumbleBee. BumbleBee simplifies building, packaging, and distributing eBPF tools by instantly generating boilerplate user-place code for creating eBPF resources. 

If that seems a little bit like Docker, you’re right it does. That is by design. BumbleBee’s code also enables you to plug its plans into other Open up Container Initiative (OCI) graphic workflows for publishing and distribution. Does this mean you could incorporate eBPF courses into a Steady Integration/Continual Advancement (CI/CD) workflow? Certainly, it does. 

Typically eBPF is applied as a safe way to greatly enhance the kernel with observability, networking, and protection systems. These courses run in response to activities this kind of as community packets arriving. Ordinarily, eBPF plans are written in a higher-degree language, these types of as C, and then Just in Time (JIT) compiled into x86 assembly for maximum overall performance and safety. 

The eBPF architecture expects eBPF courses to be loaded as bytecode, and the kernel has info constructions and formats that

Facebook Promised Poor Countries Free Internet. People Got Charged Anyway.

Facebook says it’s helping millions of the world’s poorest people get online through apps and services that allow them to use internet data free. Internal company documents show that many of these people end up being charged in amounts that collectively add up to an estimated millions of dollars a month.

To attract new users, Facebook made deals with cellular carriers in countries including Pakistan, Indonesia and the Philippines to let low-income people use a limited version of Facebook and browse some other websites without data charges. Many of the users have inexpensive cellphone plans that cost just a few dollars a month, often prepaid, for phone service and a small amount of internet data.

Because of software problems at Facebook, which it has known about and failed to correct for months, people using the apps in free mode are getting unexpectedly charged by local cellular carriers for using data. In many cases they only discover this when their prepaid plans are drained of funds.

In internal documents, employees of Facebook parent

acknowledge this is a problem. Charging people for services Facebook says are free “breaches our transparency principle,” an employee wrote in an October memo.

In the year ended July 2021, charges made by the cellular carriers to users of Facebook’s free-data products grew to an estimated total of $7.8 million a month, when purchasing power adjustments were made, from about $1.3 million a year earlier, according to a Facebook document.

The documents reviewed by The Wall Street Journal were written in the fall of 2021 and are not part of the information made public by whistleblower Frances Haugen, a former Facebook product manager.

Facebook calls the problem “leakage,” since paid services are leaking into the free apps and services. It defines leakage in internal documents as, “When users are in Free Mode and believe that the data they are using is being covered by their carrier networks, even
