    [$] Filesystems for zoned block devices

    Damien Le Moal and Naohiro Aota led a combined storage and filesystem session at the 2019 Linux Storage, Filesystem, and Memory-Management Summit (LSFMM) on filesystem work that has been done for zoned block devices. These devices have multiple zones with different characteristics; usually there are zones that can only be written in sequential order as well as conventional zones that can be written in random order. The genesis of zoned block devices is shingled magnetic recording (SMR) devices, which were created to increase the capacity of hard disks, but at the cost of some flexibility.

    Security updates for Tuesday
    Security updates have been issued by Debian (drupal7 and jackson-databind), Fedora (checkstyle and gradle), openSUSE (qemu and xen), SUSE (ffmpeg, kvm, and ucode-intel), and Ubuntu (libraw and python-urllib3).

    [$] openSUSE considers governance options
    The relationship between SUSE and the openSUSE community is currently under
    discussion as the community considers different options for how it wants
    to be organized and governed in the future. Among the options under
    consideration is the
    possibility of openSUSE setting up an entirely independent foundation, as
    it seeks greater autonomy and control over its own future and operations.

    Mourning Martin Schwidefsky
    The kernel mailing lists carry the sad news
    that longtime kernel contributor and subsystem maintainer Martin
    Schwidefsky has been killed in an accident. "Martin was the most significant contributor to the initial s390 port
    of the Linux Kernel and later the maintainer of the s390 architecture
    backend. His technical expertise as well as his mentoring skills were
    outstanding. Martin was well known for his positive mindset and his
    willingness to help.

    He will be greatly missed.

    [$] Filesystems and crash resistance

    The "guarantees" that existing filesystems make with regard to persistence in the face of a system crash was the subject of a session led by Amir Goldstein at the 2019 Linux Storage, Filesystem, and Memory-Management Summit (LSFMM). The problem is that filesystem developers are not willing to make much in the way of guarantees unless applications call fsync()—something that is not popular with application developers, who want a cheaper option.

    Firefox 67 released
    The Mozilla blog takes
    a look
    at the Firefox 67 release. "Today’s new Firefox release
    continues to bring fast and private together right at the crossroads of
    performance and security. It includes improvements that continue to keep
    Firefox fast while giving you more control and assurance through new
    features that your personal information is safe while you’re online with
    us.
    " See the release
    notes
    for more information.

    [$] Asynchronous fsync()

    The cost of fsync() is well known to filesystem developers, which is why there are efforts to provide cheaper alternatives. Ric Wheeler wanted to discuss the longstanding idea of adding an asynchronous version of fsync() in a filesystem session at the 2019 Linux Storage, Filesystem, and Memory-Management Summit (LSFMM). It turns out that what he wants may already be available via the new io_uring interface.
