  • [$] Python security transparency, par jake, 6 septembre 2017

    mercredi 6 septembre 2017 :: LWN.net :: RSS
    As Steve Dower noted in his lightning talk at the 2017 Python Language Summit, Python itself can be considered a security vulnerability—because of its power, its presence on a target system is a boon to attackers. Now, Dower is trying to address parts of that problem with a Python Enhancement Proposal (PEP) that would enable system administrators and others to detect when Python is being used for a nefarious purpose by increasing the "security transparency" of the language. It is not a solution that truly thwarts an attacker's ability to use Python in an unauthorized way, but will make it easier for administrators to detect, and eventually disable, those kinds of attacks.

  • [$] A last-minute MMU notifier change, par corbet, 6 septembre 2017

    mercredi 6 septembre 2017 :: LWN.net :: RSS
    One does not normally expect to see significant changes to an important internal memory-management mechanism in the time between the ‑rc7 prepatch and the final release for a development cycle, but that is exactly what happened just before 4.13 was released. A regression involving the memory-management unit (MMU) notifier mechanism briefly threatened to delay this release, but a last-minute scramble kept 4.13 on schedule and also resulted in a cleanup of that mechanism. This seems like a good time to look at a mechanism that Linus Torvalds called "a badly designed mistake" and how it was made to be a bit less mistaken. Lire la suite corbet
