From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Luis Chamberlain sent out the modules changes today for the Linux 6.6 merge window. Most notable with the modules update is a change that better builds up the defenses against NVIDIA's proprietary kernel driver from using GPL-only symbols. Or in other words, bits that only true open-source drivers should be utilizing and not proprietary kernel drivers like NVIDIA's default Linux driver in respecting the original kernel code author's intent.

Back in 2020 when the original defense was added, NVIDIA recommended avoiding the Linux 5.9 for the time being. They ended up having a supported driver several weeks later. It will be interesting to see this time how long Linux 6.6+ thwarts their kernel driver.

Oh wow the comments on Phoronix for this one are bonkers.

From what I understand (because it wasn't clear to me from either of the TLDRs posted here) Nvidia's proprietary graphics driver has been calling parts of the kernel that they shouldn't be, because their driver is closed source.

These seem to be parts of the kernel that another company may own patents to, but has only licensed it to the kernel for free use with GPL open source code only, i.e. closed source/proprietary code is not allowed to use it.

Nvidia seems to have open sourced a tiny communication shim to try and bypass this restriction, so their closed source driver talks to the shim, and the shim talks to the restricted code in the kernel, that Nvidia does not have a license to use. This is a DMCA violation, hence why the Kernel devs are putting in preventions to block the shim, as far as I can see.

I don't understand the small minority of commenters there defending a la soulless corp Nvidia, who is blatantly in the wrong here. Some commenters have gone as far as to call the Linux kernel maintainers "zealots", would not be surprised if they are alts for Nvidia devs...

Phoronix comments are always wild

Remind me of those who supports Red Hat for blocking sources and telling those who downstreams "code thief with no contribution to open source" lol.

I did not “support” Red Hat but I was pretty vocally in opposition to most of the reaction to it. I found the willful inaccuracy and even flagrant dishonestly from the “community” close to disgusting at times. So, you may be including people like me in your comment.

In this case, it seems very straight-forward that NVIDIA is in the wrong. Not just ethically but legally as well.

My own read is that some of the people slamming Red Hat are defending NVIDIA now. Coming away from that experience, I the over-arching principle that many adhere to most is simply whatever is best for them. Red Hat was wrong because people felt entitled to something. The kernel devs are wrong ( and NVIDIA right ) because people feel entitled to something.
