The Linux Foundation's Core Infrastructure Initiative Renews Funding for Reproducible Builds Project
The Core Infrastructure Initiative (CII) has announcedcontinued financial support for the Reproducible Builds Project."The grant extends the contribution to include Debian developersChris Lamb, Mattia Rizzolo, Ximin Luo and Vagrant Cascadian, as well asextending funding for Holger Levsen. Furthermore, this contribution addssupport for Ed Maste, working with FreeBSD." (Thanks to Paul Wise)
[$] Topics in live kernel patching
Getting live-patching capabilities into the mainline kernel has been amulti-year process. Basic patching support was merged for the 4.0 release,but further work has been stalled overdisagreements on how the consistency model — the code ensuring that a patchis safe to apply to a running kernel — should work. The addition of kernel stack validation has addressed thebiggest of the objections, so, arguably, it is time to move forward. Atthe 2016 Linux PlumbersConference, developers working on live patching got together to discusscurrent challenges and future directions.Click below (subscribers only) for the full report from LPC 2016.

Kernel prepatch 4.9-rc5
The 4.9-rc5 kernel prepatch is out. Linussays: "Things have definitely gotten smaller, so a normal releaseschedule (with rc7 being the last one) is still looking possible despitethe large size of 4.9. But let's see how things work out over the nextcouple of weeks. In the meantime, there's a lot of normal fixes in here,and we just need more testing."
Security Exercises (Linux Journal)
Over at Linux Journal, Susan Sons has a lengthy article on security exercises, which are a way to test the readiness of a project or organization for some kind of security problem. "Scheduling exercises at a predictable time and reminding others when it will happen prevents confusion among staff. It is wise to begin with low-impact exercises (more on this below) that don't leverage production systems, and move on to higher-potential-impact exercises only when the organization's infrastructure and personnel have had most of the bugs shaken out. If something as small as a runaway process on a single server can seriously impact your business, it's better to find out at a planned time with all hands on deck than at 4am on a holiday when no one who knows what to do can be reached. The whole point of security exercises is to increase resilience: raise the threshold of what is normal for your team to deal with, what your systems can shrug off." She followed that article up with some example security exercises.

Fedora 25 to have MP3 playback
Christian Schaller writesthat, after all these years, a stock Fedora system will be able to play MP3files. "I know this has been a big wishlist item for a long time fora lot of people so I am really happy that we are finally in a position tofulfill that wish. You should be able to download the mp3 plugin on day 1through GNOME Software or through the missing codec installer in variousGStreamer applications. For Fedora Workstation 26 I would not be surprisedif we decide to ship it on the install media."

[$] Making WiFi fast
Dave Täht has been working to save the Internet for the last six years (atleast). Recently, his focus has been on improving the performance ofnetworking over WiFi — performance that has been disappointing for as longas anybody can remember. The good news, as related in his 2016 Linux PlumbersConference talk, is that WiFi can be fixed, and thefixes aren't even all that hard to do. Users with the right hardware and awillingness to run experimental software can have fast WiFi now, and itshould be available for the rest of us before too long.
digiKam 5.3.0 is published
The digiKam Software Collection 5.3.0 has been released. This version isavailable as an AppImage bundle. "AppImage is an open-source project dedicated to provide a simple way to distribute portable software as compressed binary file, that standard user can run as well, without to install special dependencies. All is included into the bundle, as last Qt5 and KF5 frameworks. AppImage use Fuse file-system, which is de-compressed into a temporary directory to start the application. You don't need to install digiKam on your system to be able to use it. Better, you can use the official digiKam from your Linux distribution in parallel, and test the new version without any conflict with one used in production. This permit to quickly test a new release without to wait an official package dedicated for your Linux box. Another AppImage advantage is to be able to provide quickly a pre-release bundle to test last patches applied to source code, outside the releases plan."

Project for porting C to Rust gains Mozilla's backing (InfoWorld)
InfoWorld takesa look at a C-to-Rust translation project called Corrode. "What Corrode does not do (yet) is take constructs specific to C and rewrite them in memory-safe Rust equivalents. In other words, it performs the initial grunt work involved in porting a project from C to Rust, but it leaves the heavier lifting -- for example, using Rust's idioms and language features -- to the developer."

Kernel prepatch 4.9-rc3
The 4.9-rc3 prepatch is out. "Itturns out that the bug that we thought was due to the new virtually mappedstacks during the rc2 release wasn't due to that at all, but a blockrequest queuing race condition. So people who turned off the new featureweren't actually avoiding it at all." The new feature appears to besolid, but more testing is always welcome.
What comes after ‘iptables’? Its successor, of course: `nftables` (RH blog)
The Red Hat Developers Blog is running anintroduction to the nftables packet filtering system."nftables implements a set of instructions, called expressions, whichcan exchange data by storing or loading it in a number of registers. Inother words, the nftables core can be seen as a virtualmachine. Applications like the nftables front end-tool nft can use theexpressions offered by the kernel to mimic the old iptables matches whilegaining more flexibility."
Formatted kernel documentation at kernel.org

[$] Defending against Rowhammer in the kernel
The Rowhammervulnerability affects hardware at the deepest levels. It has proved to besurprisingly exploitable on a number of different systems, leavingsecurity-oriented developers at a loss. Since it is a hardwarevulnerability, it would appear that solutions, too, must be placed in thehardware. Now, though, an interesting software-based mitigation mechanismis under discussion on the linux-kernel mailing list. The ultimateeffectiveness of this defense is unproven, but it does show that there maybe hope for a solution that doesn't require buying new computers.

Gregg: DTrace for Linux 2016
Brendan Gregg celebratesthe capabilities of Linux kernel tracing with BPF. "With thefinal major capability for BPF tracing (timed sampling) merging in Linux4.9-rc1, the Linux kernel now has raw capabilities similar to thoseprovided by DTrace, the advanced tracer from Solaris. As a long time DTraceuser and expert, this is an exciting milestone! On Linux, you can nowanalyze the performance of applications and the kernel usingproduction-safe low-overhead custom tracing, with latency histograms,frequency counts, and more."

The initial bus1 patch posting
The bus1 message-passing mechanism is the successor to the "kdbus" project;it was covered here in August. The patches have now been posted for review."While bus1 emerged out of the kdbus project, bus1 was started fromscratch and the concepts have little in common. In a nutshell, bus1provides a capability-based IPC system, similar in nature to AndroidBinder, Cap'n Proto, and seL4."
