@kernellogger @kees @gregkh I also considered using the repo, especially the nice json files under cve/published/. However, the README[1] under cve/ made me hesitate. Quoting the part that made me unsure if it can be used.

For now, ignore this as we are getting things working properly…

Yet another academic paper[1] exploring DAMON for tiered memory management will be presented at EuroSys 2024[2].

The CVE team released their first two CVEs:

* CVE-2023-52433: netfilter: nft_set_rbtree: skip sync GC for new elements in this transaction
https://lore.kernel.org/linux-cve-announce/2024022058-outsell-equator-e1c5@gregkh/

* CVE-2024-26581: netfilter: nft_set_rbtree: skip end interval element from gc
https://lore.kernel.org/linux-cve-announce/2024022024-uniquely-recluse-d893@gregkh/

For more details on the new CVE process, see https://docs.kernel.org/process/cve.html (recently added by https://git.kernel.org/torvalds/c/5928d411557ec5d53832cdd39fc443704a3e5b77 )

DAMO v2.2.2 is released. The important change in this release is the introduction of 'replay' command[1]. It receives 'damo record' output and replay the recorded access pattern. Hopefully it will help reproducing the real-world's memory access pattern for analysis and benchmarks. The command is in an experimental level and not formally documented at the moment, though.

I just marked my linux kernel mails management tool as v1 (https://sjp38.github.io/post/hackermail_v1/). I hope it answers the questions on my mails management workflow, better than I did in the past.

@alexmurray @gregkh Maybe this document explains some of the reasons? https://docs.kernel.org/process/security-bugs.html#disclosure-and-embargoed-information

DAMON talk for OSSummit NA 2024 has been accepted and scheduled[1]. The talk will present DAMOS auto-tuning and hopefully, more new DAMO features. The features are still under development, but hopefully, the power of presentation-driven development will make it. ;) Looking forward to meeting you there!

@amit @paulmckrcu Pretty much. I was able to start RCX[1] research project all owing to the experience from the translation of the book and some trivial contributions for Paul's artifacts. And RCU is only a small part of the things that I learned from Paul. :)

Linux is now a CNA: http://www.kroah.com/log/blog/2024/02/13/linux-is-a-cna/

This has taken a long time, I'd like to thank all the groups that helped, and especially the CVE group themselves. Our application was a bit different than other groups, but they understood that this is important for security overall.

After about 8 years of progress on my little hobby project[1], the Korean translation of @paulmckrcu 's book, I'm marking it as completed a humble milestone[2]. It was a very fun and informative journey.

Yesterday, I received a newsletter saying Google Bard now supports image creation. So I asked Bard to create some DAMON logo candidates. Bard is not perfect, but draws definitely better than I :)
