[SOLVED] kernel: platform regulatory.0: Direct firmware load for regulatory.db failed with error -2

I've been getting

Quote:

kernel: platform regulatory.0: Direct firmware load for regulatory.db failed with error -2

since I upgraded to kernel 4.15. I don't see that this causes a problem.

Does the file exist in /lib/firmware?

How did you get the 4.15 kernel? Did you compile on your own (there might be a missing config option) or you installed from your distribution?

I build my own. What config option would I be missing?

Documentation/networking/regulatory.txt reads

Quote:

When the regulatory domain is first set up, the kernel will request a database file (regulatory.db) containing all the regulatory rules.

It points to a source for making one's regulatory.db (which, unfortunately errors for me; I'll have to dig into it.)

This started for me Jan 29 16:21:04, after I upgraded to kernel 4.15 ; /usr/src/linux/net/wireless/reg.c has the code that reports it.

Anyone know much about this?

I compiled many of the 4.15x kernels in Slackware and I see the same thing.

I'm trying to figure out if I'm missing a system package, or compile option, or if this is a bug?

Thanks

It's in the CRDA package.

Of course it's CRDA and I have it installed...

That's not what I was asking, I'm asking why the regulatory.db failed in the logs and how to fix?

kernel: cfg80211: failed to load regulatory.db
kernel: platform regulatory.0: Direct firmware load for regulatory.db failed with error -2

Then you have a different problem than the one I started this thread with.

Do /lib/firmware/regulatory.db and /lib/firmware/regulatory.db.p7s exist?

Hmm you started the post with the same thing as me;

kernel: platform regulatory.0: Direct firmware load for regulatory.db failed with error -2

Not sure where this is a different problem?

I don't have either files in /lib/firmware...

I'm not running WiFi at the moment, would this be the reason there is no regulatory.db and regulatory.db.p7s?

I solved my problem by upgrading to the most-recent CRDA package.

It's because you haven't installed the most-recent CRDA package.

I run the Stable Tree which is 14.2, and that only has crda-3.18-x86_64-3, that is the only version if you run 14.2.

So I'm assuming you're talking about the version crda-3.18-x86_64-5 from 'Current'?

Yes.

You can download the current package, extract those 2 files (which don't exist in previous versions), put them in /lib/firmware.

I think that current is stable. You may want to ask in the Slackware forum. I update to current daily, rarely had a problem, then only minor.

I upgraded with crda-3.18-x86_64-6, which is now the 'current' version and it works!

WoOT
