HN discussionI've described how we (the kernel security team) handles this type of things many times, and even summarized it in the past here: http://www.kroah.com/log/blog/2018/02/05/linux-kernel-releas... Scroll down to the section entitled "Security" for the details. If you wish to disagree with how we handle all of this, wonderful, we will be glad to discuss it on the mailing lists. Just don't try to rehash all the same old…

HN discussion> Windows is noticeably slower than Linux or Mac on the same hardware. Isn't that a problem? Windows isn't slower at running Windows apps, fitting into a Windows infrastructure (Active Directory, management tools, Exchange etc), using Windows device drivers, working with NTFS volumes and their features, backwards compatibility, printers etc. It all comes down to what the goals of the users (or purchasers) are, and I…

HN discussion> It's in integrating the fickle whims of myriad hardware devices with amazingly high expectations of reliability and performance consistency under diverse workloads. So much this; Linux Plumbers conference years ago was bitching about how every gorram vendor wanted to be a special snowflake, so even though the architecture was ARM, you basically had to port the kernel all over again to every new phone. I haven't ke…

HN discussionseverity on cve is a crapshoot most of the time, but especially with linux cna. i would not advise relying on them for decision making. "We can not assign severity [...] So any group that attempts to give a “severity score” to a Linux CVE is lying to you, UNLESS they know exactly your use case. ALWAYS ignore any attempt that groups such as NIST/NVD that purport to assign things like CVSS scores to a vulnerability. T…

HN discussionmy understanding is that while Google is following the letter of the GPL and giving back their changes to the GPL'd code, they are not putting fourth the effort to get those changes integrated with the rest of the linux kernel, so practically speaking, you aren't going to be seeing much of the android changes outside of android. http://www.kroah.com/log/linux/android-kernel-problems.html

HN discussionThe Linux developer community promised almost 20 years ago [1] that no release of the stable kernel will ever break something that worked in a stable kernel before. AFAICT, this promise holds. If you upstream your driver, the community will take care (cf. AMD), if you don't your users experience occasional pain (cf. NVidia).

HN discussion> I don't think I'm explaining myself well. Can't the kernel be modified so that manufacturer-specific code can stay in-house? The kernel is under the GPLv2 so redistributing kernel binaries also requires making source available (that is all part of the "freedom"). The kernel internals constantly change. For example the USB stack was rewritten 4 times. Each time all the drivers etc were converted over. By contrast M…
