Maintaining DAMON (https://damonitor.github.io). All opinions are my own.

Because my airplane was delayed, I played with kernel CVE data, and summarized[1] the buggy and error-full results.

TL; DR: About 95% of CVEs that affect the mainline tree has fixed before those are reported by linux_kernel_cves project. The number was 76%, 69%, 73%, 78%, 83% and 82% for 6.4.y, 6.1.y, 5.15.y, 5.10.y, 5.4.y, 4.19.y, and 4.14.y, respectively.

The worst case time between linux_kernel_cves report and fix commit being fixed was [16, 32) weeks for the mainline. For the stable trees, the number was [4, 8) weeks (6.4.y), [16, 32) weeks (6.1.y and 5.15.y), [32, 64) weeks (5.10.y), [64, 128) weeks for 5.4.y, [32, 64) weeks (4.19.y and 4.14.y).

We started running DAMON functionality tests suite[1] for a few kernels including all DAMON-available stable kernels from the early stage of DAMON project. Recently, we further started testing stable-rc kernels and sending[2] the results to stable@. I now feel this is making DAMON healthier. After all, this makes my name listed on the stable kernel version update commit[3] ;) So I would recommend more people to have some fun with stable-rc kernels and take their credit if they want.

One of my unofficial and personal goals for 2023 was to create 100 GitHub stars with the DAMON user space tool (damo)[1], and while I hoped it would be realized at least by the end of 2023, we achieved it much sooner than expected - just one day after our 100th release!

DAMON user-space tool (damo) has released[1] its 100th version. A mail[2] for the news, release stats, and appreciation to the DAMON community has also posted. From the mail:

"Looking forward to 200th, and 1,000th release of damo :D We, the community,
will make it together."

Hocus wrote a great article[1] that made some comments[2] on hackernews. It introduces DAMON as a kernel feature that could be useful for memory efficient VM, with its limitations. Definitely DAMON needs more improvement, and we’re working[3] for that.

DAMON talk for OSSummit EU 2023 has accepted and scheduled[1]. The talk will focus on its user-space tool, damo. It's mainly for helping more audiences to digest the content easier, and also for accelerating the development of damo. By the time, hopefully the version of damo would reach to, or exceed 2.0.0, and newer interface and features will be introduced together. Looking forward to the conference!

It's been a great week at LSFMMBPF and OSSummit NA. Best of all, I don't think I'll be wasting any time shopping for t-shirts for a while.

Linus Torvalds

Pet peeve of the day: all the people talking about how ChatGPT is not “conscious” and how it does not “understand” what it is saying, but just putting likely-sounding words together into likely-sounding sentences.

Extra bonus points for using an example of a math problem as a way to show how these AI chat-bots talk about things they don’t really understand.

The irony. The lack of self-awareness. It burns.
