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.

a) Good for them

b) How long before NVIDIA throws up their hands at the whole thing and does their own Linux distro + pushes all their cloud AI customers to use it? (it doesn't seem like they're ever going to be shamed / coerced into actually open-sourcing their driver)

Would having their own distro even help? It seems like working around this would require forking from Linux at a lower level, and even that would only circumvent technical (rather than copyright) barriers.

B) can't happen because of gpl. Even if it could, not many customers will move to an nvidia distro. ML people need good distros and good drivers.

If a hypothetical nvidia distro would speed up training by 10% but cause drop of productivity of humans of as small as 5%, no many will "buy" it. We can throw more hardware, people are the bottleneck nowadays

That's just such a great image!

Yeah they'd do that with a card that looks like it's from 2003 with those classic dual DVI ports. Stole it right out of some kid's Quake 3 box. Try that with a 4090.

Just installed the nvidia-driver for my 2080 SUPER and my system isn't starting now. I'm using Debian 12.1 and after installing the driver, it crashes after entering in my password for my encrypted drive.

I will load up a Live USB and see if I can fix the issue. Any help would be appreciated!

This is the best summary I could come up with:


The Linux 6.6 modules infrastructure is changing to better protect against the illicit behavior of NVIDIA's proprietary kernel driver.

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.

Given that symbol_get was only ever intended for tightly cooperating modules using very internal symbols it is logical to restrict it to being used on EXPORY_SYMBOL_GPL and prevent nvidia from costly DMCA circumvention of access controls lawsuits.

Luis Chamberlain further added in today's pull request: "Christoph Hellwig's symbol_get() fix to Nvidia's efforts to circumvent the protection he put in place in year 2020 to prevent proprietary modules from using GPL only symbols, and also ensuring proprietary modules which export symbols grandfather their taint.

The circumvention tactic used by Nvidia was to use symbol_get() to purposely swift through proprietary module symbols and completley bypass our traditional EXPORT_SYMBOL*() annotations and community agreed upon restrictions."

Back in 2020 when the original defense was added, NVIDIA recommended avoiding the Linux 5.9 for the time being.
