The GNU C Library (glibc) is the core C library for most Linux distributions, so it is a crucial part of the open-source ecosystem—and an attractive target for any attackers looking to carry out supply-chain attacks. With that being the case, securing the project's...
Mahé Tardy led two sessions about some of the challenges that he, Kornilios Kourtis, and John Fastabend have run into in their work on Tetragon (Apache-licensed BPF-based security monitoring software) at the Linux Storage, Filesystem, Memory Management, and BPF Summit. The ...
Canonical's Launchpad software-collaboration platform that is used for Ubuntu development will be shutting down its hosted mailing lists at the end of October. The announcement recommends Discourse or Launchpad Answers as alternatives. Ubuntu's mailing lists are unaffected...
The increasing sophistication of attackers has organizations realizing that perimeter-based security models are inadequate. Many are planning to transition their internal networks to a zero-trust architecture. This requires every communication on the network to be encrypted, ...

Srinivas Narayana led a remote session about extending Agni to prove the correctness of the BPF verifier's handling of different execution paths as part of the Linux Storage, Filesystem, Memory Management, and BPF Summit. The problem of ensuring the correctness of path...
Cory Doctorow wears many hats: digital activist, science-fiction author, journalist, and more. He has also written many books, both fiction and non-fiction, runs the Pluralistic blog, is a visiting professor, and is an advisor to the Electronic Frontier Foundation (EFF); his ...

The BPF verifier is an increasingly complex and security-critical piece of code. When the kinds of people who are apt to work on BPF see a situation like that, they naturally question whether it's possible to use formal verification to ensure that the implementation of the...
