[$] No hardware memory isolation for BPF programs
On February 12, Yeoreum Yun posted a suggestion for an improvement to the security of the kernel's BPF implementation: use memory protection keys to prevent unauthorized access to memory by BPF programs. Yun wanted to put the topic on the list for discussion at the Linux Storage, Filesystem, Memory Management, and BPF Summit in May, but the lack of engagement makes that unlikely. They also have a patch set implementing some of the proposed changes, but has not yet shared that with the mailing list. Yun's proposal does not seem likely to be accepted in its current form, but the kernel has added hardware-based hardening options in the past, sometimes after substantial discussion.
[$] An effort to secure the Network Time Protocol
The Network Time Protocol (NTP) debuted in 1985; it is a universally used, open specification that is deeply important for all sorts of activities we take for granted. It also, despite a number of efforts, remains stubbornly unsecured. Ruben Nijveld presented work at FOSDEM 2026 to speed adoption of the thus-far largely ignored standard for securing NTP traffic: IETF's RFC-8915 that specifies Network Time Security (NTS) for NTP.

Restarting LibreOffice Online
We plan to reopen the repository for LibreOffice Online at The Document Foundation for contributions, but provide warnings about the state of the repository until TDF's team agrees that it's safe and usable – while at the same time encourage the community to join in with code, technologies and other contributions that can be used to move forward.
Meanwhile, this post from Michael Meeks suggests that the tension around online versions of LibreOffice has not abated.
