[$] Development statistics for the 6.5 kernel

Post Syndicated from corbet original https://lwn.net/Articles/941675/

The 6.5 kernel was released
on August 27 after a nine-week development cycle. By that time, some
13,561 non-merge changesets had found their way into the mainline
repository, the lowest number seen since the 5.15 release (12,377
changesets) in late 2021. Nonetheless, quite a bit of significant work was
done in this cycle; read on for a look at where that work came from.

Bugzilla Celebrates 25 Years With Special Announcements (Bugzilla blog)

Post Syndicated from jake original https://lwn.net/Articles/942937/

August 26 was the 25th anniversary of the release of the Bugzilla bug tracker as open-source software under the Mozilla Public License (MPL). A blog post for the occasion has some announcements, including several upcoming releases, help wanted, and a new legal entity to house the project:

Which now brings us to today, when I’m happy to announce the formation of Zarro Boogs Corporation, which will now be overseeing the Bugzilla Project. This is a taxable non-profit non-charitable corporation – we have filed with the IRS our intent to operate under US Tax Code §501(c)(4) (still pending approval from the IRS) meaning the IRS would require us to spend money raised on project expenses and not make a profit, but money donated to us will not earn you a tax deduction because we aren’t a charity (software development is not considered a charitable cause in the US). Unlike Thunderbird, which is a subsidiary of the Mozilla Foundation, we are an independent entity not owned by or associated with the Mozilla Foundation, although they have licensed the use of the Bugzilla trademark to us.

Remotely Stopping Polish Trains

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2023/08/remotely-stopping-polish-trains.html

Turns out that it’s easy to broadcast radio commands that force Polish trains to stop:

…the saboteurs appear to have sent simple so-called “radio-stop” commands via radio frequency to the trains they targeted. Because the trains use a radio system that lacks encryption or authentication for those commands, Olejnik says, anyone with as little as $30 of off-the-shelf radio equipment can broadcast the command to a Polish train­—sending a series of three acoustic tones at a 150.100 megahertz frequency­—and trigger their emergency stop function.

“It is three tonal messages sent consecutively. Once the radio equipment receives it, the locomotive goes to a halt,” Olejnik says, pointing to a document outlining trains’ different technical standards in the European Union that describes the “radio-stop” command used in the Polish system. In fact, Olejnik says that the ability to send the command has been described in Polish radio and train forums and on YouTube for years. “Everybody could do this. Even teenagers trolling. The frequencies are known. The tones are known. The equipment is cheap.”

Even so, this is being described as a cyberattack.

The 6.5 kernel has been released

Post Syndicated from corbet original https://lwn.net/Articles/942876/

Linus has, as expected, released the 6.5
kernel
.

I still have this nagging feeling that a lot of people are on
vacation and that things have been quiet partly due to that. But
this release has been going smoothly, so that’s probably just me
being paranoid. The biggest patches this last week were literally
just to our selftests.

Headline features in 6.5 include
faster booting on large x86 systems,
Arm Permission Indirection Extension
support,
Rust 1.68.2 support,
unaccepted memory handling,
“mount beneath” support for filesystems,
the cachestat() system call,
the ability to pass a pidfd via a SCM_CREDENTIALS control message,
scope-based resource management for
internal kernel code,
the deprecation of the SLAB allocator,
and more. See the LWN merge-window summaries
(part 1,
part 2) and the (in-progress)
KernelNewbies 6.5 page
for details.
