Over on the OpenMandriva forum, the Linux distribution has reported sabotage of its repositories by a disgruntled contributor with administrative credentials. According to "AngryPenguin", an abusive incident in a distribution Matrix chat led to a user being kicked out of the chat; that "triggered a cascade of events", which led to people resigning from the distribution. Eventually, one of those people used their administrative privileges to delete part of the distribution's GitHub repository and to "publish an empty package in the cooker repository, which obsoleted all gnome and cosmic packages, which could have damaged the systems of people using gnome or cosmic".

We are currently working to restore the deleted repositories and restore the functionality of the obsolete packages.

[...] We performed a full system audit and, aside from the removed packages, we found no other violations.

A number of problems related to negative directory entries (dentries) were the topic of a filesystem-track session at the 2026 Linux Storage, Filesystem, Memory Management, and BPF Summit. Negative dentries are used to indicate that a file of a given name does not exist in a directory; it is an optimization that short-circuits the lookup of the file name when the answer is already known. Miklos Szeredi led a session that discussed some problems that come from having too many negative dentries for a directory.
