Security updates for Thursday
Security updates have been issued by CentOS (freeradius, kernel, libvirt, and qemu-kvm), Debian (intel-microcode, linux-4.9, and samba), Fedora (kernel, kernel-headers, memcached, microcode_ctl, php-pecl-imagick, and samba), Mageia (kernel, kernel-linus, kernel-tmb, and microcode), openSUSE (389-ds, bzip2, jakarta-commons-fileupload, kernel, and pacemaker), Red Hat (flash-plugin and ruby), Scientific Linux (kernel, libvirt, qemu-kvm, and ruby), Slackware (rdesktop), and Ubuntu (libvirt). | | 3:48p |
Last 3.18.x stable release: 3.18.140 Greg Kroah-Hartman has announced the release of the 3.18.140 stable kernel. " Note, this is the LAST 3.18.y release that I will be doing on
kernel.org. I know it has been marked as End-of-Life for quite some
time, but I have kept it alive due to a few million phones out there in
the wild that depend on it, and can not move to a new kernel base due to
them being stuck with a SoC vendor that does not work upstream.
But, this does not mean the tree is dead, oh no, if only it were that
easy..." He and others will be updating the kernel in the Android Open Source Project (AOSP) tree. | | 4:26p |
[$] Telling the scheduler about thermal pressure Even with radiators and fans, a system's CPUs can overheat. When that happens, the kernel's thermal governor will cap the maximum frequency of that CPU to allow it to cool. The scheduler, however, is not aware that the CPU's capacity has changed; it may schedule more work than optimal in the current conditions, leading to a performance degradation. Recently, Thara Gopinath did some research and posted a patch set to address this problem. The solution adds an interface to inform the scheduler about thermal events so that it can assign tasks better and thus improve the overall system performance. | | 4:53p |
Coverage from the Python Language Summit Over the past four years, LWN has covered the Python
Language Summit, but this year the Python Software Foundation (PSF) elected to go in a different direction, with coverage by A. Jesse Jiryu Davis on the PSF blog. Those reports are being gathered on a summit
page; as of this writing there are two reports up with plenty more to come. " The Python Language Summit is a small gathering of Python
language implementers, both the core developers of CPython and alternative
Pythons, held on the first day of PyCon. The summit features short
presentations from Python developers and community members, followed by
longer discussions. The 2019 summit is the first held since Guido van
Rossum stepped down as Benevolent Dictator for Life, replaced by a
five-member Steering Council." |
